Will COVID evolve to cause less severe disease? Why we can’t assume the answer is yes – San Francisco Chronicle

Posted: June 26, 2022 at 10:23 pm

When scientists find a new disease-causing virus in humans, the first question they want answered is: Can this thing spread easily from person to person? And if not, will it someday?

Avian influenza can infect humans, but its not very good at passing from one person to another. Same with the coronavirus that causes MERS, another severe respiratory illness. Though hundreds of cases of both have been reported over the past two decades, neither virus seems inclined to evolve toward efficient person-to-person transmission.

In less than three years, the coronavirus that causes COVID-19 has mastered it.

SARS-CoV-2 has accumulated a suite of mutations over an astonishingly short period of time that have made it now one of the most infectious human pathogens on the planet. And for the first time ever, scientists have the tools and the knowledge to closely track that evolution in near-real time, studying the small but mighty genomic mutations that have transformed the virus to the point where it hardly resembles the strain that began infecting humans in China in late 2019.

Mapping the evolution of this virus has fed academically curious minds in every nation, and its had real world implications too. Identifying and describing new variants has helped guide public health responses and is now informing the next generation of vaccines and drug therapies.

The coronavirus rapid evolution also is helping scientists anticipate the future of the pandemic, and what mutations may make it a less or more formidable foe in years to come.

This is the first time in human history that weve been able to witness a global pandemic at the genomic, evolutionary level, said Joe DeRisi, president of San Franciscos Chan Zuckerberg Biohub, which has done genomic sequencing on the virus since the start of the pandemic.

Whats been especially fascinating, and at times alarming, is the speed of this virus evolution. That SARS-CoV-2 would mutate to better adapt to humans was always anticipated, but the pace of that adaptation has been breathtaking.

Scientists say thats in large part due to the scale of the pandemic more than half a billion infections worldwide have afforded the virus near-boundless opportunity to mutate. But its a matter of timing, too. As a human virus, SARS-CoV-2 is still in its infancy, developing rapidly to flourish in its new environment. Meanwhile, human immunity to the virus due to infection and vaccination has become increasingly complex, applying constant pressure to further evolve.

Its normal to see this kind of evolution this constant battle between human and pathogen, said Fenyong Liu, an infectious disease expert at UC Berkeleys School of Public Health. Each of us is focused on survival. We develop a better system to beat them, and theyre going to mutate and try to escape. It happens with all infectious diseases, but for COVID, the whole process really sped up because of the scale of it.

Predicting how evolution will shape the next iterations of this virus is tricky, and scientists lack the technology to do it with any precision. How the virus has mutated over the past two and a half years provides some clues: Scientists have identified dozens of specific mutations mostly associated with increasing infectiousness that have recurred in multiple variants. Those mutations likely will keep showing up, re-sorting themselves in different combinations that give the virus further survival advantages. Some of the mutations could become permanently embedded in the virus genetic code. A few already have.

Recently, the virus has mutated to evade hard-won human immunity, and most experts in virology believe it will continue down that evolutionary path. It could also acquire new mutations that make it more infectious, though its already become so efficient at spreading among humans that its hard to imagine how much more gains it can make there, some scientists say.

The most critical question and possibly the toughest to answer is whether the virus will evolve to cause more or less severe disease in humans. Many experts believe that viruses tend to become more benign over time one of the current coronaviruses that now causes the common cold may have been the source of a deadly pandemic in the late 1800s but thats not a sure thing, and no one can say how long such evolution may take. Omicron and its subvariants are causing milder disease than their predecessors, but it would be nave to assume a future variant couldnt arrive with mutations that make it fiercer once again, experts say.

Social distancing circles at Dolores Park on Saturday, May 23, 2020, in San Francisco. The 10-foot circles, which were eight feet apart from each other, were an effort to curb coronavirus spread.

Hopefully it will adapt and become a very mild seasonal disease, and our immune systems will adapt, too, Liu said. But in reality, the virus has unlimited capability to adapt and mutate.

Scientists began tracking the evolution of SARS-CoV-2 almost immediately after the virus was isolated and identified in early January 2020. Once the first genomic sequence was complete and had been shared on a public database, infectious disease experts around the world started hunting for mutations, largely to keep tabs on how the virus was spreading.

Most people by now are familiar with the role mutations play in giving the virus certain advantages. But most mutations dont actually have an obvious effect on the virus, theyre simply glitches in the code. Those mutations can serve as evolutionary breadcrumbs, though, allowing scientists to follow the virus trail as it travels widely around the globe. And throughout the pandemic, public health experts have used mutations to identify and control clusters of infections.

Still, scientists are most invested in tracking consequential mutations that may alter the public health response. For example, arrival of the incredibly infectious omicron led many officials to recommend people start wearing higher quality masks, and eventually triggered another universal mask mandate in California to help curb the spread.

The most influential mutations mostly have been identified in the spike protein, the section of the virus that projects out of the surface and latches onto the ACE2 receptor, a protein on the exterior of human cells through which SARS-CoV-2 gains entry.

The first significant mutation known as D614G and nicknamed Doug arrived sometime in spring 2020; it basically made the ACE2 receptor more accessible. It was like putting a wedge in the door to keep it open, said Shannon Bennett, chief of science at the California Academy of Sciences.

Shannon Bennett, chief of science for the California Academy of Sciences, studies infectious diseases that can be transmitted from animals to humans. Here, she plays her piano at her home on March 20, 2020, in Mill Valley, Calif.

That mutation granted the virus an early boost in infectiousness, and it has stuck around in every important variant since. Identifying a mutation of that significance was surprising, and exciting, Bennett said. It was the kind of early evolutionary shift that scientists have never been able to capture before. With earlier viruses HIV, for example by the time scientists identified and were able to study them closely enough to look for mutations, they were already well established in humans and had likely gone through years of vigorous adaptations.

After D614G, the virus quickly accumulated mutations that mostly improved its ability to transmit and infect. Scientists havent yet determined exactly what all those changes are doing, at the biological level, to increase infectiousness. Some may allow the virus to replicate faster in the nose or bind more tightly to the ACE2 receptor, making it harder for the immune system to shake off an early infection. Mutations could also make the virus more durable, for instance able to survive for longer periods in the air.

By the end of 2020, it was becoming apparent that the virus was evolving quickly in an environment of widespread transmission. Troubling new variants were emerging at regular intervals, each causing new waves of infection in the country in which they emerged and sometimes on a global scale. And each new variant seemed to be at least somewhat more infectious than the one preceding it. Alpha, which dominated in the U.S. in early 2021, was perhaps 50% more infectious than the original virus, and delta, which fueled the summer 2021 surge, was perhaps 90% more infectious than alpha.

Nurse practitioner Paige Yang mixes a dose of Evusheld, a preventative monoclonal injection, at Total Infusion in Oakland, Calif. on March 16, 2022. The medication is used to prevent COVID-19 among immunocompromised patients.

Omicron, which carried dozens of new mutations, was again more infectious up to fivefold over delta. And each of its subvariants has been more infectious still. The currently circulating strains, all offspring of omicron, are nearly as infectious as measles, which is the most contagious of all known human infections.

Scientists say the virus may have hit peak infectiousness, or close to it. Now, its evolving to get around the immune response, and that trend likely will continue. Early studies show that the two up-and-coming variants in the U.S. BA.4 and BA.5, which currently make up roughly a third of cases are the most immune evasive so far; people who are vaccinated or have already been infected, or both, may still be vulnerable.

I think theres a max in terms of how transmissible it can be, said Nadia Roan, an investigator at the Gladstone Institutes in San Francisco who studies immunology. Now almost the entire world has some form of immunity, whether from infection or vaccination or both, and thats the big pressure. A virus that is able to take off right now has to be immune evasive.

Scientist Xiaoyu Luo, postdoctoral scholar Julie Frouard, lead scientist Nadia Roan, PhD, and research assistant Matthew McGregor wear masks and lab coats while walking through the lab at Gladstone Institutes in San Francisco on Thursday, August 13, 2020.

Immune evasion is such a concern that many experts believe the world needs to focus resources on developing next-generation vaccines that will target parts of the virus less prone to mutations. Manufacturers of the two main U.S. vaccines Pfizer and Moderna are working to update their products to better match the currently circulating variants, but thats difficult to do when the dominant variant changes every few months.

Ideally, scientists would develop a vaccine that neutralizes the virus preventing it from ever taking hold and stopping transmission entirely and doesnt fade over time. The latter may not be possible, though. It doesnt seem that this coronavirus will be inducing the same immunity that polio and measles induces that lasts for your entire life, said Raul Andino, a UCSF virologist.

Eventually, the pace of evolution in SARS-CoV-2 may slow down, or at least produce fewer consequential mutations that cause fresh surges several times a year. But its tough to guess when that will happen.

Virus evolution is relentless. The virus never takes a rest, never takes a break, and it never stops mutating, DeRisi said. The truce may come when we figure out what kind of yearly boosters we need, or what vaccination works.

We want to get the virus to where it just doesnt matter anymore, he said. Were not there yet. But theres reason to be optimistic, and also reason to be cautious and not let our guard down.

Queen Mary’s longtime caretaker Evolution Hospitality will enter 5-year agreement to manage ship – Signal Tribune

Posted: at 10:23 pm

Evolution Hospitality, the Queen Marys caretaker for the past year, will enter into a five-year management agreement with the City to get the ship reopened to the public.

I know many of the residents here are excited to see more activity and events come back to life in our Queen Mary, Councilmember Suely Saro said during a Tuesday council meeting. I know that we went through a very hard time with the Queen Mary.

The ship has a long history of failed operators, one of which defaulted on their loan and two of which filed for bankruptcythe most recent being Urban Commons via Eagle Hospitality in 2021.

Before, in the past 40 years, weve really tried to manage this asset by shifting all the requirements, all the responsibilities, but also all the benefits to a private company, City Manager Tom Modica said, noting that operators were often saddled with debt to obtain the lease in the first place. That proved really not to be a model that was successful.

Instead of continuing with the failed model, the City is sparking up a management agreement with Evolution Hospitality to manage the ship in exchange for a portion of the areas revenues.

The City retains significantly more responsibility for this asset [the Queen Mary], such as major capital improvements. But the City also is entitled to a majority of net profits generated at the site, said Johnny Vallejo, acting director of the Economic Development Department.

That means that the City is required to pay for larger capital improvements for restoration and preservation, of which there are plenty. A 2017 marine survey estimated a $289 million price tag for long-term repairs and maintenance of the historic ship.

Evolution will be responsible for maintaining the ship and will retain a historic resource advisor to assist them.

For the past decade, Evolution Hospitality has been the caretaker of core maintenance and security of the ship and surrounding area. The company is a subsidiary of Aimbridge Hospitality, one of the worlds largest hotel operators.

This is what almost anyone does who owns a hotel property. They then bring on someone whos a hotel expert and these are one of the best experts in the nation, Modica said. So they do it for a percent of the gross revenue [] If history is any indication, this property all made money for the hotel itself.

Under the five-year agreement, Evolution Hospitality will be responsible for the Queen Mary leasehold area, including the ship and adjacent parking. The company will operate the Queen Mary Hotel, attractions, retail, food and beverage, parking and ship-based special events.

The management agreement includes buffers for past misfortunes: additional auditing mechanisms, such as mandatory monthly financial reports, annual audited financial reports and proposed budgets for capital projects and expenditures.

During an investigation into the operation of the Queen Mary, former operator Urban Commons refused to hand over certain financial records, despite the Citys right to audit the financials of the company.

It is incredibly important that we have access to the operation fund to help manage that operation fund, to audit, we have access to that, Vice Mayor Rex Richarson said. The performance standards, I think are good, there is an incentive to do well.

The City will pay an estimated $2.87 million for pre-opening and reopening costs for the ship, paid by the Tidelands Area Fund Group and year-end budget savings.

The rest is here:

Kayzo Fosters the Next Evolution of Electronic-Rock Music With Third Album, "New Breed" – EDM.com

Posted: at 10:23 pm

The release of NEW BREEDmarks the decisive beginning of a new chapter for Kayzo, one of the biggest electronic dance music producer success stories of the 2010s.

With his latest album,Kayzo explores the intersection of rock and electronic music more thoroughlymore thoughtfullythan ever before.

Longtime fans will fondly remember records such as his remix of "Last Resort" alongside Papa Roach as breakthrough moments in his meteoric career. But while such tracks combining dubstep production with rock sonics were fresh at the time, a new spark was needed to illuminate this creative pathway ahead.

And with NEW BREED,Kayzo handily delivers.If there's one central accomplishment Kayzo can claim on the album, it's blending the many diverse rock influences with biting electronic production to create a cohesive experience.

Kayzo.

Listeners got a taste of this with his recent single "POSER" (withconner)a pop-punk-inspired anthem wherein the electronic influence feels strategically augmentative, oftentimes subtle and overall seamlessly engrained in the DNA of the production. Kayzo's creative approach here continues with "BOTTLE OF RAIN," a gloomy rock offering with a lo-fi flare; and the energizing "WASTE AWAY," with yearning vocals from Kala.

For fans of Kayzo's earlier works, he's by no means forgotten how to blow the doors off. The album's titular track is a rollercoaster ride traversing multiple bass music genres before ending with a stampeding mix of hardstyle and dubstep at its coda. Meanwhile, PhaseOne and Aaron Pauley join Kayzo for "MEET YOU IN THE SOUND," taking no prisoners in a cathartic melodic dubstep concoction.

For a risk-taking blend of Kayzo old and new, "LOVE ME HATE ME" finds a seemingly perfect balance. The track additionally stands as a highlight since he's joined by long-time partner CRAY in what marks their first collaborative offering together.

Ancient Egyptian Weapons: The Evolution of Warfare – Ancient Origins

Posted: at 10:23 pm

Anyone interested in the history of warfare or weaponry should make sure to look at ancient Egyptian weapons and how the Egyptian armies utilized their technological superiority. Whilst most famous for its architectural wonders, ancient Egypt once wielded the most terrifying fighting force the world had ever seen. The history of the rise and eventual fall of Egypts military is ultimately all about ancient Egyptian weapons!

The Egyptian weapons of the Early Dynastic Period (3150 BC-2613 BC) were as simple as one might expect. Military weapons consisted of basic daggers, spears, and maces for melee combat along with primitive bows for long-range combat.

The spears were rudimentary and very similar to those used by predynastic Egyptian hunters . The only real advancement was the introduction of copper spearheads, which offered better penetration than the traditional flint tip. However, metallurgy in this early period was expensive and it is unclear how widespread the use of copper spear tips was among the average foot soldiers.

Troops carried a dagger as a secondary weapon. The dagger normally had a copper blade and was used at either very close range or to finish off wounded enemies. The blades were too brittle to be reliable in one-to-one combat. The second they hit bone or another blade they were likely to chip or even snap, which was less than ideal.

The mace was another secondary weapon issued to some foot soldiers. The heads were either made of hardwood or pear-shaped stone. The mace could be used to smash through enemy shields or dispatch wounded enemies with one quick blow to the skull.

For longer ranges, the Egyptians began to use archers during this period. However, these rudimentary single-arched bows werent much use. They were difficult to draw, had an embarrassingly short range, and were inaccurate to boot. These problems were compounded by the fact that archers were drawn from low-class peasantry who mostly had no experience in bow hunting.

The early foot soldiers of Egypt, in the Middle Kingdom, had simple ancient Egyptian weapons: a shield, a spear and probably a dagger but not much more! Wooden figures of the Egyptian army of the 11th Dynasty found in the tomb of Mesehti. (Udimu / CC BY-SA 3.0 )

Things begin to change for the Egyptian army with the rise of Mentuhotep II of Thebes. In early Egypt, the empire was made up of different regions all led by individual nomarchs (regional leaders with their own armies) who answered to the central government. If the central government called, you and your army came running.

These small armies mostly consisted of poorly trained and poorly equipped peasant conscripts. The thinking of the time was why waste expensive equipment and training on peasant cannon fodder?

Mentuhotep was not a fan of this system though. In 2050 BC he defeated the central government's ruling party at Herakleopolis and in doing so united the country. Egypt was now solely under the control of the Thebans.

With one united army the Egyptians could focus on military development. Previously the smaller militias had been made up of disposable peasants. As such the approach to weapons had been cheap and not very cheerful. But a proper military needed proper soldiers wielding proper weaponry.

Soldiers were now commonly armed with a dagger, sword, spear, and shield. The dagger and sword hadnt evolved much. They were both crude copper blades riveted to a handle. These rivets were a major structural weak point. The longer-bladed swords were especially prone to snapping when attempting to block an incoming blow.

Archers still carried the same single arched bows as before. These came with all the same weaknesses. However, the Egyptian army became much better at utilizing these less-than-ideal weapons. Archers were now better trained and organized.

If troops were lucky they were equipped with the all-new slicing ax. This was a long wooden shaft with a crescent copper blade attached at the end via a notch. The slicing ax was a two-handed weapon with excellent range. As the name implies the ax was swung in a slicing motion (much like a scythe).

The weapon was brutally effective. Its heavyweight and momentum meant that it was next to impossible to guard against an incoming swing. A sword simply wasnt strong enough and would snap while the ax could also brute force its way through the rudimentary wooden shields of the time.

Finally, as foot soldiers were now an investment and less disposable, protective gear became more popular and troops were given simple leather armor. The protection offered was minimal but offered some protection from glancing blows or an errant long-range arrow. When it comes to armor, something is better than nothing.

Towards the end of the Middle Kingdom, the central government became increasingly complacent and weak. They took their eyes off the ball and allowed the Hyksos, a dangerous military culture who spoke a Western Semitic language and were likely Canaanites, to infiltrate their lands.

While the central Egyptian government was distracted by petty infighting, the Hyksos managed to take over lower Egypt around the city of Avaris. The Hyksos quickly established themselves and began inflicting their will on the area both politically and militarily.

The Hyksos originated from western Asia , and they were way more technologically advanced than the Egyptians. They had horse-drawn war chariots , composite bows, and more advanced weapon designs. And their melee weapons werent so prone to snapping. For every weapon the Egyptians could field, the Hyksos already had a better version.

The Hyksos became the bogeyman of the Second Intermediate Period of Egypt (1782-1570 BC). This period is often described as the Hyksos Invasion. Propaganda from The New Kingdom Of Egypt and Manethos Josephus makes the Hyksos sound like blood-thirsty monsters who swept across Egypt, destroying everything in their path. However, there is no archaeological evidence for this level of destruction.

During the Intermediate Period, the Hyksos held Egypts lower (north) ports and the Nubians had much of upper (south) Egypt. Only Thebes was still ruled by Egyptians at this point. It was time to fight back.

Under Ahmose I of Thebes the Egyptians took what they learned from the Hyksos and used it against them. Ahmose I defeated the Hyksos and ejected them from lower Egypt. He then went south and did the same to the Nubians. Once again Egypt was unified, and the age of the New Kingdom had begun.

The New Kingdom was an age of unparalleled military expansion for Egypt. Never again would they be the victims of foreign invasion. As Egypt's borders expanded and it met new enemies the Egyptians continued the rapid technological advancement of their forces.

Their armies would soon become virtually unbeatable.

The spear remained largely unchanged. It was still essentially a long stick with a sharp point at the end, but the sharp point was now made from bronze which was much better at holding an edge. The spear was still inexpensive but effective and remained the primary weapon of most Egyptian troops.

The key change was the introduction of spear and shield tactics. Spearmen were equipped with shields made of wooden boards bound with animal glue and hides. The shields were basic but effective. Spearmen could hold up behind their shields and block enemy attacks before striking back with devastating medium-range spear blows.

The javelin was an evolution of the simple spear. Soldiers would carry a quiver full of javelins. These weapons were dual purpose. They could either be used as short-range spears or launched at enemy chariots and troops. Importantly javelins were equipped with diamond-shaped metal blades that were armor-piercing.

The javelin was light, well-balanced, and easy to throw accurately. Unlike arrows, it was also reusable. As Egyptian troops advanced they could reclaim thrown javelins.

Up until this period, Egypt had been using the aforementioned slicing ax. Against unarmored foes, this was still the go-to weapon, and hard to improve upon. But what if your enemy was armored?

The Egyptians soon encountered the Hittite and Syrian armies. These army's troops wore reinforced leather jerkins which were adept at repelling slicing weapons. The Egyptians once again adapted, and the new battle-ax was born. It had a narrow, straight-edged blade designed to punch through armor with minimal resistance.

Around this time the Egyptians also discovered that utility in a weapon could be invaluable. During one pitched battle against a Canaanite city half the Egyptian army used their axes to dig beneath the city's defenses whilst the other half used their axes to level the citys surrounding forests.

In the new and improved battle ax, the Egyptians had invented an early form of entrenching tool that is still widely used by armies today.

Before the Hyksos invasion, Egyptian swords had been brittle and easy to break. The Hyksos introduced critical advances in bronze casting technology. Now the Egyptians could cast swords as one solid piece: blade and hilt all in one. With no rivets serving as weak points the swords had greatly increased durability.

This increased durability meant that swords became much more widely used. There were two common designs: a short, dagger-shaped blade for close-range stabbing, and a longer blade designed for slashing at slightly longer ranges.

What happens when you combine an ax with a short sword? You get the brutal-looking Khopesh. A moon-curved blade with the sharp edge on the outside, the Khopesh was simply terrifying to behold.

The Khopesh is another design that the Egyptians pilfered from the Hyksos. It was predominantly used as a secondary weapon used to dispatch wounded enemy soldiers with one gruesome strike. Due to its vicious-looking curve, the Khopesh became a weapon of terror. Pharaohs were often depicted in paintings wielding the Khopesh to put down entire enemy armies.

Though this is not an ancient Egyptian composite bow it is identical to what King Tutankhamens military wielded and a huge improvement in range over the earlier simple hunting bows. The bow depicted here is Turkish, from 171920 AD, and made from horn, wood, pigment, sinew, lacquer, gold, silver, ivory, iron, feather, silk. (TheMet / Public domain )

Whilst all the weapons so far had seen major improvements, none of them was as much of a gamer changer as the composite bow. Another gift of the Hyksos invasion, the composite bow completely changed how the Egyptian army approached combat.

The composite bow was long with a recurved shape. The bow was made by combining layers of Birchwood, animal horn, cattle tendons, and sinews that were all glued together. This layered construction method, combined with the shape meant the bow was much more powerful than previous designs.

A skilled archer could easily reach 250-300 meters (820-984 feet) and could fire each arrow in less than two seconds. This gave the composite bow a rate of fire and effective range comparable to some modern firearms. Unsurprisingly, it was devastatingly effective on the battlefield.

A platoon of 50 archers outfitted with these bows could inflict heavy losses on an enemy long before they had a chance to fight back, destroying morale. The only downside? The bows were incredibly expensive to make and maintain. Rather than ask for gold Egyptian armies would often ask for new composite bows as a tribute. It is said that after defeating the Libyans Ramses III demanded over six hundred composite bows in tribute.

Egyptian war chariots were also adapted from Hyksos designs, but the Egyptian improvements were significant. This stone panel was found at the Great Temple of Ramses II in Abu Simbel, south Egypt. (Warren LeMay / CC0)

The most impressive and deadly new weapon of the New Kingdom was the chariot. The Hyksos had introduced the Egyptians to the idea of a lightweight chariot used in battle, but the Egyptians perfected it.

A war chariot was manned by two warriors. One would drive the horses and focus on short-range defense while an archer in the back focused on long-range attack. The chariot was lightweight but laden with weapons- quivers of arrows and javelins were attached to the sides along with khopeshes and battle axes.

One chariot on its own was terrifying but the Egyptian army would use formations of more than 100 chariots to cut through enemy lines and decimate their flank. The chariot was essentially a mobile weapons platform zipping around the battlefield at crazy speeds.

The war chariot was no glass cannon though. The charioteers and their horses were encased in scale armor. They wore coats of bronze scales which protected them from long-range attacks whilst cranking up the intimidation factor even higher.

The combination of these heavily armored and armed war chariots and the fielding of the composite bow made the Egyptian army one of the most advanced and unbeatable in the world. They also made it one of the most expensive.

If the Egyptian army had become so impressive theres only one question left. What went wrong?

Just like every empire that came before and every empire that has come since the New Kingdom eventually entered a decline and began to crumble under its own weight. A grand army needs grand leadership and that became increasingly rare. Egypt soon found itself without the resources or leadership required to wield such an impressive army.

Looking at the ancient Egyptian army and its weapons provides an important lesson in humility. Without effective leadership, a large army is little more than a weight around a country's neck. It doesnt matter how massive or technologically advanced your army is, no one stays top dog forever.

R2AK: Will monohulls sweep the podium? – Scuttlebutt Sailing News

After the race was cancelled in 2020 and 2021, the 6th edition of the 750 mile Race to Alaska (R2AK) began June 13 with a 40-mile proving stage from Port Townsend, WA to Victoria, BC. For those that survived, they started the remaining 710 miles on June 16 to Ketchikan, AK. Heres the day six report:

The bookies over at the Ketchikan Chamber of Commerce are divvying up the cash stakes everyone laid on the off chance they would be the ones to precisely predict the arrival time of first place. The total winnings are undisclosed, but were betting its not paid in candy corn, and it will make at least 1.5 dreams come true.

Also, true to form, 10,000 dollars of highly suspect bills were nailed to the wall of the Alaska Fish House last night, with the simple dare to the crew of Team Pure and Wild. If you sailed here to get it, then get it.

This is also the exact moment Tracker Acolytes global-wide take a quick beat and proclaim another R2AK decided and done. However, if you spent more than a thumb-scrolling minute with us, youre reaching for the third bag of Jiffy Pop, checking the anchor or mood lighting or poorly fluffed pillow, and waiting for the stories to play out.

R2AK is like an Ayn Rand novel written by a lesser Bronte, and its not until page 300 of this 1400-page tome that youll even get to understand what the hell its about because maybe what is most noble about this activity isnt the play-by-play of who does what; its what lives in the heart, and its a long beat.

At time of writing, a crew of three have claimed $10,000; quickly subtracted the cost of removing a perfectly functioning engine from their boat, shipping said engine, and reinserting it two weeks later; donating a grand of the winnings to SeaShare; then calculated time taken off from work, food, supplies, costs of returning the boat, Ketchikan expenses (lets see carry the one, move the decimal left a couple times); and have seen prize money go from black to a deep crimson red.Heart wins over math every time.

Over 359 Canada-goose-flying miles, 24 teams remain in play, taking part in astounding and distinctly different activities. The race for runner-up remains on, and the monohulls are best positioned to sweep the podium. This happened only in 2018, so not without precedent but with a lot of past multihull winners shaking their collective heads.

Teams Elsewhere (Soverel 33) and Fashionably Late (Dash 34) find themselves in a drag race arguably more exciting than the Melges showdown and knockdown fest that happened in the very same waters in 2019. In fact, the thrum on tightly tuned Spectra and stainless steel is echoing throughout the whole of the Canadian North Coast.

The spoiler could be Vegemite Vigilantes (Corsair 760 Sport trimaran), particularly as Fashionably Late has opted for an inside route around Duke Island that is looking a bit dookie. Hold your nose and hold on.

On June 23, the steak knife winners could be declared (or not) along with a gash of Pacific weather strong enough to hunker down in or double your wager. Either way, 24 teams row, sail, pedal, or paddle to a challenge two years in the making and one day closer to achieving it.

Race to Alaska, now in its 6th year, follows the same general rules which launched this madness in 2015. No motor, no support, through wild frontier, navigating by sail or peddle/paddle (but at some point both) the 750 cold water miles from Port Townsend, Washington to Ketchikan, Alaska.

To save people from themselves, and possibly fulfill event insurance coverage requirements, the distance is divided into two stages. Anyone that completes the 40-mile crossing from Port Townsend to Victoria, BC can pass Go and proceed. Those that fail Stage 1 go to R2AK Jail. Their race is done. Here is the 2022 plan:

Stage 1 Race start: June 13 Port Townsend, WashingtonStage 2 Race start: June 16 Victoria, BC

There is $10,000 if you finish first, a set of steak knives if youre second. Cathartic elation if you can simply complete the course. R2AK is a self-supported race with no supply drops and no safety net. Any boat without an engine can enter.

In 2019, there were 48 starters for Stage 1 and 37 finishers. Of those finishers, 35 took on Stage 2 of which 10 were tagged as DNF. There were no races in 2020 and 2021 due to the pandemic.

Bill Maher Addressed an Eventful Political Week on Real Time – InsideHook

Posted: at 10:22 pm

Fridays Real Time With Bill Maher was the last episode to air before the show takes a month-long break. (Itll return on July 29.) Given the weeks Supreme Court decisions, Maher and his guests had no shortage of topics to choose from but the overall effect was more understated than one might expect.

Maher addressed the way that the aforementioned legal rulings represented a break from the status quo many Americans had thought would never change. From there, he spoke about considering returning to his running I know why youre happy gag, but commented that it wasnt the week for it. If youre keeping score at home, its Guns 1, Women 0, he said. And from there, Maher talked about Trumps influence lingering after he left office. Hes like a fart with bad hair, said Maher.

Maher went on to discuss Clarence Thomass concurring opinion and the continuing revelations from the January 6 hearings. Perhaps the most charged moment happened when Maher alluded to the testimony Rusty Bowers gave in the hearings, and found that his name elicited little to no reaction. No one watches the news at my show? Maher asked in disbelief then quickly summarized the Trump presidency in a handful of words.

Christine Emba, author of Rethinking Sex: A Provocation, was Mahers first guest. Youre here on an interesting day, Maher said. Emba described herself as completely shocked at the ruling, and noted that the ruling in question was counter to public opinion. The countrys moving in two very different directions, Maher replied.

Maher then asked Emba about her book and, more broadly, about the role of technology in modern relationships. Emba spoke about the complexity inherent to using apps for relationships including the way that dating apps can reduce some of the confusion regarding interactions potentially leading to romance and/or sex.

Emba went on to speak about the legacy of the #MeToo movement; Maher, for his part, was more critical of the internets role in both dating and the spread of porn. (Maher was highly critical about the role of the internet in spreading porn.) Emba shared several of the conversations shed had while researching her book, and the conceptual grey areas that emerged. And from there, Maher spoke about evolving attitudes towards sex.

We cant both be sluts, Maher said. And before long, it was time to segue to the panel discussion, featuring Andrew Sullivan and Katie Herzog. Maher spoke of the Republican Party playing the long game when it came to Supreme Court appointments, while Sullivan was more skeptical, noting that a Clinton victory in 2016 would have dramatically changed the Court.

Maher brought up the subject of an increasingly divided United States and brought up a few comparisons, including to Israel and Palestine, Belgium and the former Czechoslovakia. Sullivan was more skeptical of this, arguing that things had been this way for a while, and that this made sense due to federalism.

Sullivan went on to talk about the case that had caused Roe to be overturned and that the 15-week limit for abortions was higher than what youll find in Germany. Though Herzog was quick to point out that due to the difference in healthcare systems between the two countries someone would likely find out about a pregnancy much sooner in Germany than they would in the United States.

Sullivan went on to argue that Republicans would likely face a po;itical price for the Supreme Courts recent ruling. He went on to make the case for more centrism and expressed his frustration at the Biden presidency. This, in turn, led to a discussion of trans kids, gender roles, and the governments position on both.

Were going to get killed just for having this discussion, Maher said at one point, addressing the fact that all three have been criticized in the past for their comments on trans people. While Mahers show at its best can bring together people with differing beliefs, there was a general sense of agreement among the three speakers. And, again there was also the frustrating element of a heated discussion of trans rights without any trans people taking part.

In the second half of the segment, Maher mentioned that hed been unaware of drag queen story hours before a few weeks earlier. The Right is all about parents rights until the parents do something they dont like, Sullivan said and went on to make a long and impassioned defense of drag queens. For his part, Maher offered a compromise between right and left: a drag queen story hour where the works of Ayn Rand were read.

Emba joined the panelists for Overtime, where the first question addressed the FDAs ban of Juul. Herzog spoke about her frustration with this position, and argued that Juul had helped smokers wean themselves from cigarettes. This segued into a larger description of smoking and the devices one could use to smoke, whether it be tobacco or weed.

Somehow, this ended up turning into a heated discussion of menthol cigarettes and whether younger generations are having fewer children and, in terms of the latter, whether thats a good thing from an environmental perspective.

And then came New Rules, where Maher expressed horror at the idea of ketchup-flavored popsicles. (Which, to be honest, is understandable.) Also up for discussion? Monkeypox and the goblin sharks Tinder photo. The bulk of the segment focused on Democrats losing demographic groups who have historically voted for them with Mahers argument being, essentially, an extended metaphor about good lawyers and bad lawyers.

At least, thats how it began with Maher returning to some of the subjects that irk him the most (such as the term Latinx), before making a grander point about policy stances that could potentially stand in the way of bipartisan actions. The Democrats need to be like the lawyers you see on billboards, Maher said. Though the conclusion he reached that Democrats should keep Trump from attempting to interfere in another election didnt necessarily seem to contradict any of the policy stances he had critiqued earlier in the segment. It was an odd note on which to close the episode; lets see where Maher and the nation are in a months time.

The state reported nine new COVID-19 cases in Harvard for the week ending June 11, seven more than reported the previous week, bringing the towns cumulative number of state-reported cases since the pandemic began to 696. Testing at the schools is over for the year.

The Board of Health told the Press that the Food and Drug Administration has just authorized a three-month shelf-life extension for all iHealth COVID-19 tests with expiration dates on or before Sept. 29, 2022. Other test brands may also be extending expiration dates; check the manufacturers website for further information.

Between June 14 and June 20, the state reported 8,834 new confirmed COVID-19 cases, down from 11,189 new cases the previous week. On June 20, there were 469 hospitalizations reported, 53 fewer than a week earlier; the number of ICU patients increased from 36 to 53 during the week ending June 20. The state reported 43 deaths during that same week, 32 fewer than the previous week.

The percentage of the 5,373 Harvard residents eligible for the vaccine (5 and older) and fully vaccinated remained at 86.9% over the week ending June 14; the partially vaccinated percentage increased from 9.1% to 9.2% that same week. For the week ending June 14, the total number of residents with at least one booster increased by 21 and is currently 3,257. Vaccination numbers in the state report for Harvard do not include Devens residents or inmates at its Federal Medical Center.

On June 21 the Federal Bureau of Prisons website reported no new COVID-19 cases among inmates at the Federal Medical Center in Devens for the eighth week in a row. There was one case among staff, one more than last week. Since the pandemic began, 372 of the current inmates and 202 staff have recovered from COVID-19; 13 inmates died of the virus.

Note that case numbers reported by the state do not include people who tested positive only with an at-home test.

Hospitals bound to patient safety rules that aren’t all backed by evidence – EurekAlert

Posted: at 10:21 pm

CHICAGO --- If health care facilities such as hospitals and nursing homes dont follow patient safety rules set by The Joint Commission (TJC) the independent organization responsible for accrediting health care facilities they may lose their accreditation, and consequently, lose patients and millions of dollars every year in funding.

But what if those rules arent supported by evidence?

A new Northwestern Medicine study found of the new rules issued during a one-year period by the TJC, many did not appear to be supported by published evidence. The study showed only six of 20 rules were directly supported by references cited by TJC, six were partly supported and eight were not supported at all.

This paper is among the first to show that TJC may issue rules or standards for hospitals, nursing homes and other health care facilities that are not backed by evidence showing these are necessary or important for patient safety or health.

While this study only reviewed new rules during a one-year period, the implication is that many rules issued in the past may similarly not be supported by published evidence, the study authors said.

The study will be published June 23 in the British Medical Journal.

Why does it matter?

Following the rules or standards set by TJC can be expensive and use hospital resources and staff time, said lead study author Dr. Murad Alam, vice chair and professor of dermatology at Northwestern University Feinberg School of Medicine and a Northwestern Medicine physician. "In fact, we started this study because we were approached by colleagues frustrated by TJC rules. As an example, TJC requires hospitals to discard drugs past their printed expiration dates, which results in billions wasted every year, even though the FDA's own Self Life Extension Program has shown that most of the drugs tested were perfectly safe and effective for many years longer.

Because TJC rules are so influential and impactful, it is important that these rules really improve patient care and safety. Our finding is concerning because unhelpful rules can waste money in the health care system and take attention from more important activities.

A common way to justify a rule is to show that evidence, including previous medical studies, improve the quality or safety of care. TJC, when issuing new standards and rules, often lists citations, or the names of medical articles it believes show the value of these rules, Alam said.

However, when the study authors went back to read these articles listed in support of the new rules, they found, in many cases, the articles provided little to no convincing information that the particular standards or rules being recommended by TJC would improve safety or quality of care.

Hundreds of millions of patients, hospital employees, staff affected by TJC rules

Potentially hundreds of millions of patients and millions of hospital employees and staff are affected by TJC rules and standards since the vast majority of U.S. hospitals are accredited by the Joint Commission.

We all pay the cost, in terms of insurance premiums and out-of-pocket health expenses, to ensure that hospitals are safe and high quality, with some of this going to make sure that TJC standards are followed, Alam said.

Given that money for health care is limited, we want to make sure that our dollars are being used to truly ensure safety and quality and not just to do busy work that sounds important but doesnt really make a difference in how patients fare, Alam said.

When TJC standards are not supported by evidence, if TJC still believes these are important, they should provide patients, doctors and administrators with other reasons why these standards should be implemented, he said.

In medicine, evidence is often the basis of what we do or dont do, and doctors, researchers and regulators are expected to be transparent in sharing the evidence that influences their behavior, Alam said.

Alam stressed the paper is not critical of TJC's mission, motives or importance.

TJC standards are important and often extremely helpful in making health care very safe and in reducing medical errors, Alam said. We must give a great deal of credit to TJC for being at the forefront of protecting patients in the U.S. We also admire TJC for constantly striving to improve health care safety and quality by considering new standards that may further reduce medical errors. This is an outstanding organization, which we are fortunate to have.
