CASCADE LOCKS, Ore., Dec. 20, 2021 /PRNewswire/ -- This year's report includes new data on the carbon reduction that results from renewing products as compared to making new ones.

TRW Leading Circular 2021 - The Climate Crisis, Carbon and Circular

Brands can achieve an average reduction of 51.5% in carbon emissions by renewing an existing product instead of producing a new one.

Renewal is the process TRW created to restore apparel, bags and home goods to standardized conditions enabling more uses over longer periods of time with a lower carbon impact than new ones.

Equally important, this year's Leading Circular highlights the voices of activists who are cutting through the noise on what the industry should be paying attention to when it comes to carbon and circularity.

Dominique Drakeford's essay states how the current approach to circular continues "the colonial control of power dynamics while keeping the veil of 'Doing good for people and planet' as a facade of noble action."

Liz Ricketts essay, She Can No Longer Carry Us, is a first person account of the impact in Ghana of US over production. Her concluding words must be heard. "Just because you do not see and feel the weight of fashion's excess does not mean it is not there closing in on us and destroying the industry we love."

re/make authors Ayesha Barenblat, Elizabeth Cline and Chelsey Grasso address the myth that we can recycle our way out of the climate crisis. "In general, brands have to stop taking the low-hanging fruit of recycling and work towards the reuse and product life extension aspects of circularity."

"Climate change is the largest existential crisis facing humanity. It is this urgency that frames the Leading Circular 2021 report on Carbon and Circularity." Says Co Founders Nicole Bassett and Jeff Denby. "We are calling on every apparel and textile brand to commit to displacing 10% of new production over the next 5 years and invest those resources into renewal."

For Some, Manchin’s Sign Off Is A Matter Of Life And Breath – Above the Law

Posted: at 1:34 am

Technology has carried coal miners far from needing to rely on canaries. Unfortunately, black lung is still a reality they work with as they do the dirty work that keeps our lights on. Bidens Build Back Better infrastructure looked like a light at the end of the tunnel. But unfortunately Sen. Joe Manchins sooty. You know what? Ill stop with the coal-mining puns, but I want you to appreciate that an effort was made. The takeaway is that this thing is damned important.

The labor union noted that the bill includes an extension of a fund that provides benefits to coal miners suffering from black lung disease, which expires at the end of the year. The [United Mine Workers of America] also touted tax incentives that encourage manufacturers to build facilities in coalfields that would employ thousands of miners who lost their jobs.

This is a spit in the face, considering that Mr. Manchin owns stock in a coal brokerage firm, pushed for provisions in the bill that would land coal workers clean energy gigs, and was named an honorary member of the UMWA last year. For whatever reason, it looks like Manchin is flip-flopping on his support of the bill. This wouldnt usually be that big of a deal politicians flip flop like flapjacks but Manchins vote is likely the one that would end a 50/50 deadlock, so he matters.

My hope is that Manchin falls back into the vein UMWA is familiar with him in supporting workers. Christmas is coming up, and while there are a few kids who deserve to be on the naughty list, no kid deserves a Christmas without mom or dad because they caught the black lung.

Extension Specialist Silliman on 20 Years Serving NC Cooperative Extension | Agricultural and Human Sciences | NC State University – NC State CALS

Posted: at 1:34 am

Ben Silliman, professor and youth development extension specialist, is an expert in family life, youth development, and program evaluation. Prior to serving in his current position at NC State, Silliman taught undergraduate and graduate courses in human development and family life at Louisiana Tech University for six years and was an associate professor and family life specialist for eight years through University of Wyoming Extension. At the University of Wyoming, he contributed to the launch of The Wyoming Children, Youth, and Families At-Risk program.

Silliman joined the Wolfpack in 2001 and has worked on diverse, interdisciplinary projects in the realm of youth development and program evaluation over the last two decades. One of his first projects was helping coordinate afterschool programs statewide, providing training to afterschool staff and support to county programs to promote positive youth development in afterschool settings. Soon after, Silliman became involved in extension evaluation efforts at the county, state and national levels, including managing the North Carolina component of the National Study of Positive Youth Development a national study that illustrated how 4-H promoted positive youth development from elementary to middle school and into high school. This was just one of a long list of projects focused on evaluating extension youth development programs that Silliman contributed to. He also contributed to the first study on the impacts of 4-H public speaking programs and a study on 4-H camping programs that used experiential learning as a tool for evaluation.

In addition to evaluating youth programs themselves, Silliman has also been dedicated to studying the ways in which extension professionals can better implement evaluation for those programs.

For one project, Silliman helped demonstrate how 4-H agents could learn-by-doing evaluation in their programs. And as part of the eXtension Evaluation Team, says Silliman, I led a study of extension professionals in four states that documented how they became engaged and enthusiastic about program evaluation in their diverse program areasand reported on their perceived needs for training and support. The results of that study, which focused on those evaluation champions, was published in the Journal of Human Sciences and Extension in 2016.

Growing demand for evidence of extension program value and effectiveness in recent years was the catalyst for another one of Sillimans key projects: serving as editor for a special edition of the Journal of Human Sciences and Extension in 2019 titled Credible and Actionable Evidence in Extension Practice: Framing Issues, Contexts and Principles.

My co-editor, Dr. Scott Cummings at Texas A&M, and I were privileged to work with some of the best minds in extension to highlight how extension makes its case for making a difference that is both scientifically sound and publicly credible, notes Silliman. We hope that our talented authors provided both key insights on how to work smarter in evaluation as well as profound challenges to the status quo in thinking about the public value of extension.

One of Sillimans key projects in recent years has been conducting evaluation research for Project YES, a college student internship program for youth from military families led by Harriett Edwards and J.C. Johnson. In addition to publishing a literature review and program rationale in Marriage and Family Review, the program model and initial outcomes in the Journal of Youth Development, and a follow-up study of long-term program impact in Child and Youth Care Review, Silliman was also involved in an in-depth interview study with program participants to assess program impact. Interviews for that study revealed how Project YES alumni from the programs first cohort were applying program development, problem solving, communication, and teamwork skills learned in the program in their personal and professional lives, and that the program supported alumni in their transition into careers via cultivating a professional identity, familiarity with work conditions and responsibilities, specialized training such as working with military youth and virtual learning, as well as 2-3 years of repeated practice in diverse team and leadership roles. In both cases, Project YES alumni credited the programs training, mentorship, and leadership opportunities as key to their growth and application of life skills in early career. I feel extremely privileged to hear and interpret their stories for the extension and youth development communities,notes Silliman.

I feel extremely grateful for the opportunity to serve the College of Agriculture and Life Sciences over the past 20 years, says Silliman. Theres still more to be done, so Ill continue to look for opportunities to teach, encourage and grow, and wish those who follow me similar rewarding experiences along that way.

His advice for students entering the field: Think about the people who plant or pick the crops that end up on your kitchen table; those who depend on you to show them how to make ends meet when the ends are pretty short; those who share their precious children with you, eager to learn and serve and grow. Think about how their hard-earned tax dollars or program fees support your comfortable lifestyle. Respect them and give them the time of day when you meet them and work as hard and creatively for them as they do for their families and employers. And God will bless you in your work.

Silliman says that his family has been blessed to be part of 4-H and getting to know some of his colleagues in their roles as youth professionals. As I retire, I look forward to perhaps using a few of the insights and lessons from my extraordinary experience to bless others who work with childrenand adults, says Silliman.

My dad worked briefly for extension and always dreamed of getting an Ag degree and going into farming but could not afford college. I am humbled to have had an experience of learning and serving in an Ag-related field and hope I have made himand CALS proud.

About Targeted Radionuclide TherapyTargeted Radionuclide Therapy is an emerging class of cancer therapeutics, which seeks to deliver radiation directly to the tumor while minimizing radiation exposure to normal tissue. Targeted radiopharmaceuticals are created by linking a therapeutic radioisotope to a targeting molecule (e.g., peptide, antibody, small molecule) that can precisely recognize tumor cells and bind to tumor-specific characteristics, like receptors on the tumor cell surface. As a result, the radioisotope accumulates at the tumor site and decays, releasing a small amount of ionizing radiation, thereby destroying the tumor. The highly precise localization enables targeted treatment with minimal impact to healthy surrounding tissue.

About n.c.a. Lutetium-177 / EndolucinBetaNo carrier-added Lutetium-177 (n.c.a. 177Lu) chloride, is a radiopharmaceutical precursor used in Targeted Radionuclide Therapy for the treatment of various diseases, like cancer. When labeled with a tumor-specific targeting molecule (e. g. peptide or antibody), the targeted radiopharmaceutical binds to a tumor-specific receptor, according to the lock and key principle. N.c.a. 177Lu has a half-life of 6.647 days and provides the highest specific activity of more than 3,000 GBq/mg at Activity Reference Time (ART). Optimal preconditions for efficient radiolabeling of biomolecules over its entire shelf-life of 9 days after production are ensured. N.c.a. 177Lu exhibits an extraordinary level of radionuclidic purity and does not contain metastable Lutetium-177m circumventing cost intensive clinical disposal management.

Beneath Canyons on Mars, Astronomers Find Potentially ‘Water-Rich Area the Size of the Netherlands’ – Smithsonian

Posted: at 1:33 am

A region within Mars's Valles Marineris (pictured) called the Candor Chaoshad a large amount of hydrogen about a meter below the surface. European Space Agency

Located below the Red Planet's equator, the Valles Marineris isone of the largest known series of canyonsin the solar system. About a meter beneath the valley's surface, astronomers have now detected a large amount of hydrogen, reports Michelle Starr forScience Alert. The discovery, published in the journalIcarus,may allow future astronauts to access water on Mars easily.

While water has been previously known to exist on Mars, most of it is found as ice caps near the poles.Water and ice havenever been found at the surface near the equator, however,because temperatures are not cold enough for it to be stable, per astatement. Other missions have looked for surface water hidden as ice on dust particles or locked within minerals.

Researchers at the European Space Agency and the Russian Space Research Institute found evidence of water underneath the cosmic tectonic fracture using the ESA-Roscosmos ExoMars Trace Gas Orbiter (TGO) probe, reports Alex Wilkins forNew Scientist.

Launched in 2016, TGO detected and mapped hydrogen in the top meter of Martian soil using an instrument dubbed Fine Resolution Epithermal Neutron Detector (FREND), reports Meghan Bartels forSpace.com. By detecting neutrons instead of light, the instrument peers through the Red Planet's dust to search for water reservoirs not picked up by other equipment. FREND can measure the hydrogen content of Mars'soil up to a meter below the surface,Science Alertreports.

"Neutrons are produced when highly energetic particles known as 'galactic cosmic rays' strike Mars; drier soils emit more neutrons than wetter ones, and so we can deduce how much water is in a soil by looking at the neutrons it emits," saysco-author Alexey Malakhov, a sceintist at the Space Research Institute of the Russian Academy of Sciences, in a statement.

Using TGO's datafrom May 2018 toFebruary 2021, the team found a large amount of hydrogen beneath the surface ofMars'version of the Grand Canyon, called Candor Chaos. If all of that hydrogen is bound into water molecules, a subsurface regionabout the size of the Netherlandscould beabout 40 percent water, explains the study's lead author Igor Mitrofanov of the Space Research Institute of the Russian Academy of Sciences, who is principal investigator of FREND, in a statement.

"We found a central part of Valles Marineris to be packed full of water far more water than we expected," Malakhov said in a statement. "This is very much like Earth's permafrost regions, where water ice permanently persists under dry soil because of the constant low temperatures."

The water, however, does not appear as abundant liquid lakes found on Earth. Instead, scientists suspectthe Martian dustis riddled with ice or water bonded to minerals,CNN'sAshley Strickland reports. Minerals in this region, however, are not know to contain much water. While ice may seem more likely based on what researchers know about other potential sources of hydrogen on Mars, the temperatures and pressure conditions in the Valles Marineris, situated just below the Martian equator, prohibit the formation of these types of water preserves,Science Alertreports.

There may be special geologic conditions that allow the water to be replenished and remain in this region, CNN reports. Researchers plan on deciphering what type of water lies within the canyon's grooves and how it remains by planning future missions that will focus on lower latitudes in this region.

"Knowing more about how and where water exists on present-day Mars is essential to understand what happened to Mars's once-abundant water, and helps our search for habitable environments, possible signs of past life, and organic materials from Mars's earliest days," saysESA physicistColin Wilsonin a statement.

UK scientist to pilot the European Space Agency’s Mars rover – E&T Magazine

Posted: at 1:33 am

A scientist from the University of Stirling in Scotland will be one of the first to pilot the European Space Agencys Mars rover when it launches next year.

The Rosalind Franklin rover will be on a mission to find life on the Red Planet when it arrives in June 2023.

It is the first to carry a drill long enough to explore molecules up to two metres below the surface, where they would be protected from the harsh radiation on the planets surface.

Dr Christian Schrder is one of five Guest Investigators who will join a panel of scientists from of different disciplines from Europe, Russia and Canada.

They will play a leading role in commanding the rover once it lands at the selected site of Oxia Planum on Mars.

The rover will spend a minimum of 211 sols (Martian days), equivalent to 230 Earth days, searching for organic carbon molecules that could tell us whether there was ever life on Mars.

Schrder was previously part of the team operating Nasas twin Mars exploration rovers, Spirit and Opportunity, from 2003 to 2019.

The mission established the past presence of liquid water on the Martian surface the most important prerequisite for life.

Over the last two decades we have learned that there was plenty of liquid water on Mars more than 3.5 billion years ago at that time, Earth and Mars were very similar and life was already well established on Earth, Schrder said.

So its conceivable that there was life on Mars, too. But even if we find the right signs, was that life independent of life on Earth? Or was it the result of meteorite exchange between Earth and Mars?

If it was independent and life originated twice within our solar system - then the universe could be swarming with life. If not, that would be less likely.

He added that he is specifically interested in the interaction between iron minerals and carbon molecules, which can give an indication of the kind of life there might have been.

He said: Radiation destroys the organic molecules on and near the surface so its important that, for the first time on a rover, ExoMars 2022 has a drill that can go two metres underground.

Once the Rosalind Franklin has landed, the rovers pilots will be based at the Rover Operation Control Centre in Turin, Italy, where the team will guide the rover over the surface of Mars.

It carries nine scientific instruments to locate the best sites for drilling and analyse the retrieved samples.

TESS discovers a planet the size of Mars but with the makeup of Mercury – Big Think

Posted: at 1:33 am

Ultra-short-period planets are small, compact worlds that whip around their stars at close range, completing an orbit and a single, scorching year in less than 24 hours. How these planets came to be in such extreme configurations is one of the continuing mysteries of exoplanetary science.

Now, astronomers have discovered an ultra-short-period planet (USP) that is also super light, reports MIT News. The planet is named GJ 367 b, and it orbits its star in just eight hours. The planet is about the size of Mars, and half as massive as the Earth, making it one of the lightest planets discovered to date.

Orbiting a nearby star that is 31 light years from our own sun, GJ 367 b is close enough that researchers could pin down properties of the planet that were not possible with previously detected USPs. For instance, the team determined that GJ 376 b is a rocky planet and likely contains a solid core of iron and nickel, similar to Mercurys interior.

Due to its extreme proximity to its star, the astronomers estimate GJ 376 b is blasted with 500 times more radiation than what the Earth receives from the sun. As a result, the planets dayside boils at up to 1,500 degrees Celsius. Under such extreme temperatures, any substantial atmosphere would have long vaporized away, along with any signs of life, at least as we know it.

But there is a chance that the planet has habitable partners. Its star is a red dwarf, or M dwarf a type of star that typically hosts multiple planets. The discovery of GJ 367 b around such a star points to the possibility for more planets in this system, which could help scientists understand the origins of GJ 376 b and other ultra-short-period planets.

For this class of star, the habitable zone would be somewhere near a month-long orbit, says team member George Ricker, senior research scientist in MITs Kavli Institute for Astrophysics and Space Research. Since this star is so close by, and so bright, we have a good chance of seeing other planets in this system. Its like theres a sign saying, Look here for extra planets!

The teams results appear today in the journalScience. The study was led by researchers from the Institute of Planetary Research at the German Aerospace Center, in collaboration with an international group of researchers, including MIT co-authors Ricker, Roland Vanderspek, and Sara Seager.

Transit tests

The new planet was discovered by NASAs Transiting Exoplanet Survey Satellite (TESS), an MIT-led mission, of which Ricker is principal investigator. TESS monitors the sky for changes in brightness of the nearest stars. Scientists look through TESS data for transits, or periodic dips in starlight that indicate a planet is crossing and briefly blocking a stars light.

For about a month in 2019, TESS recorded a patch of the southern sky that included the star GJ 376. Scientists at MIT and elsewhere analyzed the data, and detected a transiting object with an ultra-short, eight-hour orbit. They ran several tests to make sure the signal was not from a false positive source such as a foreground or background eclipsing binary star.

After confirming the object was indeed an ultra-short-period planet, they then observed the planets star more closely, using the High Accuracy Radial Velocity Planet Searcher (HARPS), an instrument installed on the European Southern Observatorys telescope in Chile.

From these measurements, they determined the planet to be among the lightest planets discovered to date, with a radius that is 72 percent, and a mass that is 55 percent, that of Earths. Such dimensions indicate that the planet likely has an iron-rich core.

The researchers then whittled down various possibilities for the planets interior composition and found the scenario that best fit the data showed that an iron core likely makes up 86 percent of the planets interior, similar to the makeup of Mercury.

Were finding a Mars-sized planet that has the composition of Mercury, says Vanderspek, principal research scientist at MIT. Its among the smallest planets detected to date, and its spinning around an M dwarf on a very tight orbit.

As scientists continue to study GJ 367 b and its star, they hope to detect signals of other planets in the system. The properties of these planets such as their spacing and orbital orientation could provide clues to how GJ 367 b and other ultra-short-period planets came to be.

Understanding how these planets get so close to their host stars is a bit of a detective story, says TESS team member Natalia Guerrero. Why is this planet missing its outer atmosphere? How did it move close in? Was this process peaceful or violent? Hopefully this system will give us a little more insight.

This research was supported in part by NASA.

Teachers, educators, and community members throughout the U.S. can nominate their favorite students in Grades 6 to 8 who have demonstrated that they have the right stuff to move past obstacles and reach their academic goals to NASAs Youve Got Perseverance awards opportunity.

The program, NASA says, will reward students whove shown that dedication with recognition all the way from Mars, courtesy of the space agencys Perseverance Rover.

The JPL Mars Rover team will honor these students by sending them personal messages beamed by the Rover from the Red Planets Jezero Crater, which it has been exploring since landing in February 2021.

Getting NASAs heaviest, most sophisticated Rover yet onto the surface of a planet hundreds of millions of miles away is a remarkable feat unto itself, Thomas Zurbuchen, associate administrator of the agencys Science Mission Directorate, said. But to do so in spite of the safety restrictions during the early days of the COVID-19 pandemic required extraordinary perseverance. And so does forging ahead as a student when the pandemic dramatically altered so much of your day-to-day life.

Teachers and community members have four opportunities to nominate students for the Youve Got Perseverance program.

Perseverance is the most complex robotic system weve ever sent to another planet, Perseverance Project Manager Jennifer Trosper of NASAs Jet Propulsion Laboratory in Pasadena said.

It has to autonomously drive five times faster than any other Mars Rover and use its science instruments to carefully select and then collect over 30 samples for pickup by a future mission, Trosper continued.

When sending instructions to Perseverance, engineers can command the Rover to echo a message back to Earth. NASAs Curiosity Rover, which has been on Mars since 2012, used the method to welcome Perseverance when it landed.

We also wanted to give some young students the opportunity to talk to our team and ask questions, said Trosper.

When the personalized messages are transmitted from Mars, the students will have a chance to share the experience with family and their classrooms via a live video chat with Perseverance Rover team members in mission control at JPL. Trosper hopes that connecting students with her team will help them see how the scientists and engineers also face challenging situations and succeed through perseverance.

The Rover brought up to seven new science instruments to Mars, including a technology demonstration to generate oxygen from the Martian atmosphere, plus the Ingenuity Mars Helicopter.

After all the planning, designing, and most of the spacecraft building, we had to dramatically change how we worked because of the COVID-19 pandemic, Trosper said. To stay safe, most team members, including Trosper herself, teleworked.

We had to finish the development and testing, as well as operate this complex Rover, with much of the team working remotely. It was almost to the point where you wondered, Is this really doable? But we just kept moving forward, faced head-on whatever issue came up, and overcame each challenge, one by one, she said.

Now the team wants to encourage the next generation to persevere in the same way to embrace the idea of overcoming seemingly impossible challenges.

Nomination windows for the Youve Got Perseverance award are planned throughout the 2021-2022 school year. Selection will be made through a lottery, with entries screened to ensure they meet the criteria. All nominated students can receive a certificate to acknowledge their perseverance.

Local News: Breaking ground on the PlyWood Trail (12/21/21) – Le Mars Daily Sentinel

Posted: at 1:33 am

(Sentinel Photo by Allen Hamil)Ground was broken in Merrill at the site of the trailhead for the portion of the PlyWood Trail heading north towards Le Mars. Donors, civic leaders and other supporters of the trail were on hand for the ceremony on Tuesday afternoon.

MERRILL The PlyWood Trail Foundation held a groundbreaking ceremony on Tuesday in Merrill.

Ryan Meyer, the Executive Director of the PlyWood Trail Foundation, said the day marks the end of the beginning part of the project.

We are very excited to be here this afternoon for our official groundbreaking ceremony, Meyer told a crowd of people gathered for the event. For those of you who have been with us since the beginning of this journey, this goes back to even pre-2015 so were seven years into this. This moment, we just want to pause and reflect. It marks a culmination of an extreme amount of work.

The groundbreaking took place at the spot which is to be turned into a trailhead for the portion of the trail which leaves Merrill to the north toward Le Mars.

Phase 1A of the project goes from the north side of Merrill over the Floyd River and ends just north of the river. The Phase 1A portion includes a pedestrian bridge over the river with the total length of Phase 1A being just under half a mile.

Work is expected to begin in the coming weeks as dirt will be moved to build up the banks on both sides of the Floyd River in preparation for a bridge that will be installed in the spring. After the bridge is in place, work to install storm sewers along with the grading and installation of the concrete trail and trailhead will occur.

On July 6, the Le Mars City Council awarded the bid for the 1A phase of the project to Godbersen-Smith at a cost of $1,513,754.24. No tax dollars are being spent as it will be funded by the PlyWood Trail Foundation and the funding sources that have donated to it.

The foundation has raised over $4 million to support the project from a combination of public and private sources. They have also sought out grants to help fund the trail.

Meyer thanked several donors including Mike Wells, whom he asked to say a few words.

Ive looked forward to this day for a long, long time, Wells told the crowd. As many of you know, Im a triathlete, Im an avid biker and Im super excited to be able to have the opportunity to have access to safe trails and continue to do the things that I love to do.

Phase 1B of the project is then expected to extend from that point to the intersection of C-38 and Key Avenue where the Le Mars Recreation Trail ends.

On Aug. 3, the Le Mars City Council approved an agreement for engineering services for Phases 1A and 1B with McClure Engineering at a cost of $231,800. The city of Le Mars was expected to pay the invoices to McClure, with the PlyWood Trail Executive Committee then reimbursing the city.

The full PlyWood Trail project is intended to connect Le Mars, Merrill, Hinton and Sioux City along an approximately 16-mile long stretch.
