Electric eel zaps do more than just stun they can alter the DNA of their victims, study suggests – Salon

Posted: December 14, 2023 at 3:37 am

When scientists attempt to transfer genetic material into an organism, they often use an electric field, a technique called "electroporation," that makes cell walls more permeable. This sophisticated form of genetic engineering is thought to be something restricted to laboratory equipment, not nature. Yet a recent study published in the journal PeerJ reveals that electric eels which produce an electric organ discharge (EOD) that can reach up to 860 volts may be able to transfer genetic material through their infamous jolts.

Researchers fromNagoya University and Kyoto University in Japan learned this by placing zebrafish larvae in the same tank as electric eels, then dousing the tank inDNA that codes for a green fluorescent protein. Afterward the scientists fed a goldfish to an electric eel, prompting it to emit pulses of up to 185 volts in the tank. (Don't worry, the fish were given anesthesia.) Within a day, some of the zebrafish larvae began to glow, indicating that the electric eel's pulses had indeed caused the fluorescent gene to be transferred into the zebrafish larvae. The fluorescence lingered for three days to a week.

While this study raises tantalizing questions, it leaves many of them unanswered. The implication of this experiment is that electric eels could directly cause gene transfers that increase biodiversity or create new species. Yet as the authors admit in the study, "this investigation represents the initial exploration of the uncharted impact of electric eel EOD, but it does not directly establish its significance within the natural environment." The researchers add that further research will be required, with corresponding author Atsuo Iida from Nagoya University telling New Scientist that he plans follow-up studies on EOD and gene transfer with smaller organisms like plankton and bacteria.

Blueface Says He Took a DNA Test That Proves He’s Not the Father of Chrisean Rock’s Son: ‘Thank You Jesus’ – Complex

Posted: at 3:37 am

Tell me why I snook an swab this babydna test results came in.iam not the father smh its a bitter sweat feeling cus I was coming around to it but definitely in my best interest thank you Jesus , he wrote on X Saturday morning. I cant even pretend like im not happy as hell.

Despite previously refuting the possibility of being Chrisean Jr.'s father, Blueface had previously referred to the child in question as his son, per messages he wrote on X following an incident where Rock was seen improperly cradling the childs head at a Walmart store.

On Monday morning, the 26-year-old rapper went live via Instagram after an incident where Rock had reportedly left the child behind with a friend named Marsh so that she could allegedly meet up with another man. When Blue caught wind of the situation, he appeared to have taken the infant from the woman and recounted the story to his followers, according to TMZ.

Rock gave birth to the baby boy on Sept. 3. Blueface shares two other children with rapper Jaidyn Alexis.

In the Shadow of Rome: Ancient DNA Recasts Balkan History – SciTechDaily

Posted: at 3:37 am

A comprehensive DNA analysis of the Balkan population from 1 to 1000 CE challenges the assumed Roman influence, revealing no Italian genetic traits. Instead, the study uncovers significant ancestry from Western Anatolia, Europe, and the Pontic-Kazakh Steppe, with a notable Slavic migration shaping modern Balkan genetics. Credit: SciTechDaily.com

Despite the Roman Empires extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a study published December 7 in the journal Cell revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empires reign.

From the 7th century CE onwards (coincident with the fall of the Western Roman Empire), large numbers of people emigrated from Eastern Europe, likely related to the arrival of Slavic-speaking populations, which resulted in present-day Balkan residents having 30%60% Slavic ancestry seen in present-day Balkan peoples.

We found this genetic signal of Slavic migration all across the Balkans, says senior author and paleogenomicist Carles Lalueza-Fox of the Institute of Evolutionary Biology (IBE:CSIC-Universitat Pompeu Fabra) and Museu de Cincies Naturals de Barcelona. This could have important social and political implications given that the Balkans has had a long history of conflict associated with their perceived identities.

Most ancient DNA studies focus on pre-historybefore the written recordbut ancient DNA methods can also provide insight into more recent historical periods, especially when used in combination with historical and archeological information.

Ancient DNA can give a lot of insight into historical periods, especially for regions where historical sources are scarce or when we dont know whether sources are biased or not, says first author and population geneticist Iigo Olalde of the University of the Basque Country (UPV/EHU). For example, most historical sources from the Balkans are written from the side of the Romans because the Slavic people didnt write at that time.

Previous studies have investigated the ancestry of people who lived in Italy and England during and after the fall of the Roman Empire, but little is known about demography and ancestry of the Balkans during this time. This region was one of the distant frontiers of the Roman Empire, which makes it interesting to study because this is clearly a place where you would expect people to come in contact with people from outside the Empire, so you can test things such as globalization, says Olalde.

To explore the population history of the Balkans and examine the influence of the rise and fall of the Roman empire, the researchers extracted DNA from 136 ancient individuals excavated from 20 different sites across the Balkansdefined as the region bounded by the Adriatic, Central Mediterranean, and Aegean Seas and the Middle and Lower Danube and Sava Rivers. These sites included large Roman cities, military fortresses, and small rural towns. The team focused on three periods: during the expansion and height of the Roman Empire (1250 CE), during the late Imperial period (circa 250550 CE), and following the Western Empires collapse (5501000 CE).

To provide cultural and historical context for the genetic data, the team collaborated with local archeologists and historians. For each grave, they documented burial type, as well as any objects buried alongside the individuals, such as coins, jewelry, pottery, tools, and weapons. The researchers also used radiocarbon dating to verify the age of 38 of the ancient individuals, which generated isotopic data that provide a window into those individuals diets.

The researchers were surprised to find no evidence of Italian Iron Age ancestry in the Balkan populations during the height of the Roman Empire. Instead, they showed that there was an influx of people from Western Anatolia, another part of the Roman Empire, during that period. They also found evidence of individual migrations into the Balkans from both within and outside the Roman Empire. Notably, a 16-year-old male who was excavated from a necropolis in a large Roman city was of 100% East African ancestry. The individual was buried with an oil lamp depicting Jupiter-related eagle iconography, but isotopic analysis of his teeth indicated that he had consumed marine protein sources during his childhood and therefore had likely grown up in a distant location.

This was the only full Eastern African individual that we analyzed, and he was also a clear outlier with respect to the diet compared to the rest of the individuals buried in the same necropolis, which tells us that this individual clearly grew up outside the borders of the Roman Empire, says Lalueza-Fox.

During the late Imperial period, between 250 and 550 CE, the researchers detected migrants with mixed ancestry from Northern Europe and the Pontic-Kazakh steppe. We found that those two ancestriescentral/northern European and Sarmatian-Scythian tended to come together, which suggests that these are likely to have been multi-ethnic confederations of moving people, says senior author and population geneticist David Reich of Harvard University.

However, these sources of ancestry disappeared after 700 CE. From 600 CE, shortly after the fall of the Western Roman Empire, there was a major influx of individuals from Eastern Europe. After 700 CE, individuals in the Balkans had very similar ancestral composition to present-day groups in the region, suggesting that these migrations resulted in the last large demographic shift in the area. These migrations coincide with recorded Slavic migrations, but the DNA analysis provides insight into the scale of these migrations that is impossible to glean from historical resources.

There have been debates about how impactful these migrations were and to what extent the spread of Slavic language was largely through cultural influences or movements of people, but our study shows that these migrations had a profound demographic effect, says Reich. More than half of the ancestry of most peoples in the Balkans today comes from the Slavic migrations, with around a third Slavic ancestry even in countries like Greece where no Slavic languages are spoken today.

The team are already planning what they call version two of the study, which will take advantage of improvements in ancient DNA technologies. We are now able to sequence hundreds of individuals from the same site, so we can go to another level of resolution and start to understand more about the social interactions and kinship between the different individuals, says Olalde.

Even microbes felt the impact of ancient climate transitions, McMaster DNA researchers find – Brighter World

Posted: at 3:37 am

Researchers at McMaster have traced the impacts of ancient ecological transitions right down to the microbial level, finding even bacteria and single-celled organisms changed as the climate around them shifted at the end of the last ice age.

Scientists in McMasters Ancient DNA Centre made the discovery while examining data from previous research that helped construct an advanced picture of environments that existed during thePleistocene-Holocene transition about 11,000 years ago.

When examining soil samples for the ancient DNA of microbial species, the researchers observed that a clear change in the mix of bacteria-like organisms called prokaryotes had occurred more than 13,000 years ago when the Mammoth-Steppe, a monolithic and fertile grassland-tundra ecosystem, collapsed in what is present-day Yukon, Canada.

There was a complete community shift, with many organisms decreasing or increasing in abundance, some disappearing completely and new ones arriving, says Tyler Murchie, lead author of a new paper based on the findings.

Murchie completed the work while a postdoctoral researcher in McMasters Department of Anthropology and isnow a scientist at BCs Hakai Institute, a non-profit research institute specializing in long-term ecological science.

This shows that the Pleistocene-Holocene transition affected everything in the ecosystem, down to microbes in the soil. It wasnt an ecological change that just affected large animals, like woolly mammoths, and grasses and trees, he says.

The studys co-authors include McMaster Ancient DNA Lab director Hendrik Poinar. It was published in the latest issue of the journal Environmental DNA.

Murchie says some types of microbes linked to the droppings of large megafauna such as woolly mammoths vanished during the Holocene transition.

Some microbes essentially disappeared from the region because they were tightly associated with the presence of mammoths, horses and bison, he says. In the data we see that organisms called archaea associated with breaking down megafaunal waste, shifted to other species that are more associated with woody plants and wetter soils.

While the study looks at the transition from a climate epoch that ended many thousands of years ago, researchers hope the findings can also inform how we discuss climate change today.

These environmental transitions have happened throughout time in different ecosystems, and its easy to think of these shifts as having primarily impacted big animals and plants, the things we typically find in fossil records. But by looking at the microbial scale, we can see the massively interconnected and reverberating effects that occur as ecosystems find new balance, says Murchie.

How Construction Companies Can Make Diversity Part of Their DNA – For Construction Pros

Posted: at 3:37 am

@Chalermphon - adobe.stock.com

During the past five years, Diversity, Equity, and Inclusion (DE&I) programs have become crucial for fostering non-discriminatory corporate cultures that welcome all individuals. While many construction companies have adopted DE&I policies and strategies, true progress comes from integrating these principles into daily operations. Beyond mere statements, DE&I must be ingrained in how businesses function and turning theory into action.

Creating a supportive culture beyond hiring involves implementing other various initiatives. One of the best ways a team can build an inclusive environment is by encouraging DE&I training up and down the organization. This shows that the company, leadership, and managers promote an inclusive and varied workplace. One that not only meets the criteria of the short-term goals of diversity but supports future growth by also focusing on retention and opportunities for career development.

Construction firms also must take proactive steps to create an equitable environment by prioritizing open communication and active employee listening to ensure varied perspectives are valued and heard. By providing platforms for dialogue, such as town halls and anonymous suggestion boxes, individuals feel empowered to express their opinions freely.

Encouraging cross-functional collaboration and team-building activities enables interactions among staff from multifaceted backgrounds, fostering mutual understanding and appreciation. Employee training programs emphasize empathy and cultural competence, promoting an open-minded atmosphere. These practices cultivate an environment where all employees feel respected, supported, and confident in expressing their unique perspectives and contributions.

Creating a fair workplace requires proactive efforts to address equity gaps and support career progression opportunities for underrepresented employees. To achieve this, forward-thinking organizations must adopt equity-conscious framework structures that recognize and address the disparities that people from underrepresented backgrounds face. One crucial step is acknowledging the uneven playing field that many individuals in underrepresented categories start with and actively working to level it.

Construction companies can implement additional support systems to promote equity, such as mentorship programs and targeted training initiatives. Mentorship can provide invaluable guidance and support to employees from underrepresented groups, helping them navigate their career paths and overcome potential obstacles. Targeted training programs can equip employees with the skills and knowledge necessary for career advancement, ensuring they have equal opportunities for growth and development.

Organizations in the building sector can establish clear pathways for career progression and ensure transparency in the promotion process. Providing employees with a clear understanding of the skills and qualifications needed for advancement can help mitigate subjective decision-making and ensure that promotions are based on merit and talent rather than bias.

Creating a truly inclusive and diverse place to work in the construction industry requires more than surface-level efforts; it demands the integration of DE&I principles into the very fabric of the company culture. DE&I panels and Employee Resource Groups (ERGs) are powerful tools to empower underrepresented employees and provide a platform to influence corporate policies. By including not only members of minority communities but also senior executives in these panels, organizations send a resounding message that diversity is not just a checkbox but rather a fundamental value embraced at the highest echelons of the business.

Recognizing and celebrating individuals who have felt marginalized or invisible is another essential aspect of fostering an empathetic environment. Through events celebrating the LGBTQ+ community, educational discussions about neurodiversity, and vibrant heritage month celebrations, organizations demonstrate their commitment to making everyone feel heard and acknowledged within their teams. These small yet impactful initiatives create an atmosphere of acceptance and belonging that resonates throughout the organization.

Companies must be committed to continuous learning and improvement. By challenging biases, providing impartial opportunities for career advancement, and actively listening to differing perspectives, leaders can build an environment where everyone feels valued, respected, and empowered to contribute their unique talents and ideas.

The rewards of embracing diversity, equity, and inclusion extend beyond fulfilling corporate social responsibility. A truly inclusive culture drives innovation, fosters creativity, and fuels business success. Construction workplaces embracing DE&I not as an isolated initiative but as an integral part of their identity pave the way for a more fair and prosperous future for their employees and their organization.

Astronauts Aboard ISS Find Lost Tomato Missing for 8 Months – PEOPLE

Posted: December 12, 2023 at 12:46 am

The mystery of the lost space tomato has been solved.

Astronauts aboard theInternational Space Station(ISS) revealed in alivestreamWednesday celebrating the space stations 25th anniversary that they finally found the missing fruit after initially blaming fellow astronautFrank Rubiofor its disappearance.

NASA's Associate Administrator Bob Cabana asked the crew near the end of the broadcast if they hid anything or lost anything that they were still looking for, to which several of the astronauts laughed.

"Well, we might have found something that someone had been looking for quite a while, NASA astronaut Jasmin Moghbeli said with a smile on her face.

She continued, "Our good friend Frank Rubio, who headed home, has been blamed for quite a while for eating the tomato. But we can exonerate him. We found the tomato."

According to Space.com, the mystery of the lost tomato had been a months-long inside joke between astronauts on the ISS, which started after Rubio harvested Red Robin dwarf tomatoes for the space stations Veg-05 experiment.

Following thetomato harvest in March, each astronaut received samples of the tomato harvest in a Ziploc bag. However, before Rubio could eat his portion, it reportedly floated away, per the outlet. The other ISS astronauts humorously didnt believe it.

The NASA astronaut reportedly first discussed the missing tomato during a livestream call on NASA Television, where he noted that he spent so many hours looking for that thing, but ultimately came up empty-handed.

"I'm sure the desiccated tomato will show up at some point and vindicate me, years in the future, Rubio said, per Space.com.

He again mentioned the lost tomato in a news conference held after returning to earth after more than a year in space. He said, per the outlet, that he had spent "1820 hours of my own time looking for the missing tomato, but it was never discovered.

"The reality of the problem, you know the humidity up there is like 17%. It's probably desiccated to the point where you couldn't tell what it was, and somebody just threw away the bag," Rubio said with a laugh. "Hopefully somebody will find it someday: a little, shriveled thing."

During the ISS crews 25th anniversary stream, they noted that they all have on multiple occasions lost items in the space station.

Luckily most of them we found again near an air vent, maybe a couple minutes, maybe a couple hours later. But it is certainly one of the challenges that you really get to learn to cope with until you get here, one of the astronauts said.

NASA astronaut will celebrate Hanukkah in space with felt menorah – Space.com

Posted: at 12:46 am

A NASA astronaut will "light" felt candles to celebrate Hanukkah in space.

NASA astronaut Jasmin Moghbeli plans to conduct the traditional lighting of the menorah in felt, given that the agency and International Space Station (ISS) wisely have restrictions against using fire aboard a spacecraft. The lighting will be done during Hanukkah, the Jewish festival which begins at sundown local time on Thursday (Dec. 7).

"My husband and little girls helped make a felt menorah, with lights for each night, that I can pin on to celebrate with them. So I'm excited to do that," Moghbeli said during a press conference in July, adding that her family celebrates both Hanukkah and Christmas.

Astronauts have found creative ways to celebrate holidays aboard the ISS over the years. Back in 2019 during Hanukkah, for example, Jewish astronaut Jessica Meirposted a photo of her feet in festive blue, neon green and purple socks, adorned with menorahs and representations of the Star of David.

Hanukkah is the Jewish festival that starts on the 25th of Kislev, a month on the Hebrew calendar that follows the cycles of the new moon. In the Gregorian calendar that much of the world uses, Hanukkah tends to fall in November or December, depending on the year.

"Hanukkah reaffirms the ideals of Judaism and commemorates in particular the rededication of the Second Temple of Jerusalem by the lighting of candles on each day of the festival," Britannica writes of the festival.

The Second Temple, a central feature of Judaism, replaced an earlier temple destroyed by the Babylonians. The newer temple stood between either 516 BCE or 350 BCE (depending on the source) and 70 CE, when it was destroyed by the Romans, according to Harvard University. While the temple was never reconstructed, the western wall persists and remains a sacred site in Judaism.

In 2023, antisemitic incidents have been rising throughout the world following an intensification of the Israel-Hamas war; you can learn more about the war and its history at the Poynter Institute. The White House released a national strategy to combat antisemitism in May, and the United Nations has guidelines for educators and online environments.

"This will be a chance for two scientists, who have received their Nobel Prize medals the day before for the discoveries of attoseconds and quantum dots, to have a conversation with astronauts," the Nobel Prize Museum wrote of the event.

"Join us to hear their perspectives on the importance of basic science, how we are constantly expanding our knowledge about the universe, and the challenges of conducting experiments in space."

Mysterious "red sprite" captured by space station astronaut – Earth.com

Posted: at 12:45 am

Red sprites, also known as red fairies are a type of transient luminous event (TLE), primarily appearing as red flashes of light occurring above thunderstorms. They are part of a larger family of upper-atmospheric phenomena linked to thunderstorm activity, alongside blue jets and elves.

Discovered only in the late 20th century, red sprites have since captivated scientists and sky-watchers alike with their elusive and spectacular nature.

ESA astronaut Andreas Mogensen captured this image of a red fairy hovering above a thundercloud as a part of the Thor-Davis experiment at Danish Technical University. Red sprites, as they are called in scientific circles, are rare Transient Luminous Events (TLEs) that form above thunderclouds. They typically emerge between 40 to 80 kilometers above Earth.

As demonstrated in the Davis camera video, thunder precedes the appearance of red fairies higher in the sky. The Davis cameras uniqueness lies in its operation. It functions more like our eyes retinas, sensitive to light changes, allowing it to capture up to the equivalent of 100,000 frames per second, unlike a standard camera.

The existence of red sprites eluded scientific documentation until 1989, largely due to their brief duration and high altitude.

Pilots had reported sightings of unusual aerial phenomena for years. However, these accounts remained anecdotal until researchers, using high-speed cameras, captured the first images of red sprites. This breakthrough paved the way for a new field of atmospheric research.

Red sprites manifest as reddish-orange flashes, often accompanied by tendrils extending both upward and downward. They typically occur in clusters and can stretch 50 to 90 kilometers above the Earths surface, into the ionosphere. The coloration is a result of nitrogen molecules in the atmosphere getting excited by the electrical discharge.

Red sprites develop in conjunction with large-scale thunderstorm activity, specifically above the intense electrical discharges of positive cloud-to-ground lightning. They are believed to arise from the imbalance in electrical charge between the upper atmosphere and the thunderclouds below.

The study of red sprites offers valuable insights into atmospheric electricity and upper-atmosphere conditions. They play a role in the Earths electrical balance and can impact various atmospheric chemical processes.

Advancements in high-speed photography and observational techniques have significantly enhanced our understanding of red sprites. Satellites, airborne observations, and ground-based photometric arrays are now instrumental in studying these transient events.

Despite advancements, observing and studying red sprites remain challenging due to their unpredictability and brief lifespan. Future research aims to better understand the impact of sprites on the atmosphere and their relation to other meteorological phenomena.

In summary, red sprites, while still shrouded in mystery, offer a fascinating glimpse into the complex interplay of Earths weather systems and atmospheric electricity. Continued research and observation promise to uncover more secrets of these ephemeral lights, deepening our understanding of our planets atmospheric dynamics.

As discussed above, red sprites are a form of upper atmospheric lightning, a spectacular and somewhat mysterious phenomenon that captures the curiosity of scientists and sky-watchers alike. Unlike the more familiar lightning that occurs within clouds or between clouds and the ground, red sprites are transient luminous events that appear high above thunderstorms, reaching into the Earths ionosphere.

The story of red sprites begins with their discovery. Although pilots had reported seeing unusual red lights above thunderstorms for decades, the scientific community largely dismissed these reports until 1989. That year, scientists at the University of Minnesota accidentally captured images of red sprites while filming a thunderstorm. This serendipitous discovery marked the beginning of focused scientific research into these elusive phenomena.

Red sprites are named for their distinct coloration. Typically, they appear as red at higher altitudes and fade to blue at lower altitudes. This coloration is due to the interaction of electrical discharges with nitrogen in the Earths atmosphere. Sprites can take various shapes, including jellyfish-like forms with tendrils extending downward and columnar shapes known as carrot sprites.

Forming at altitudes between 50 to 90 kilometers (31 to 56 miles), red sprites occur directly above large thunderstorm systems. They are fleeting, lasting only milliseconds, and are best observed at night. Their formation is thought to be linked to the intense electrical activity in thunderstorms. When a powerful positive lightning strike occurs within the cloud, it can create an imbalance in the electric field above the storm, triggering the appearance of sprites.

The study of red sprites is not just for aesthetic appreciation. It also holds significant scientific importance. Understanding sprites can provide insights into the electrical and chemical processes in the upper atmosphere. They are also thought to play a role in the Earths global electric circuit, a complex system that involves the entire planets electromagnetic environment.

Research into red sprites is challenging due to their brief and unpredictable nature. Scientists use specialized high-speed cameras and sensitive telescopes to capture and study these elusive events. Additionally, research aircraft and satellites are employed to gain a better vantage point for observing and analyzing sprites.

In recent years, public interest in red sprites has grown, thanks in part to the spread of information on social media and the increasing accessibility of high-quality cameras. Amateur astronomers, astronauts and photographers have captured stunning images of red sprites, contributing to both the publics awareness and the scientific communitys understanding of these fascinating natural phenomena.

In summary, red sprites are a mesmerizing and complex element of our planets atmospheric behavior. They represent a beautiful intersection of earth science and atmospheric physics, offering both aesthetic wonder and scientific intrigue. As research continues, we can expect to learn more about how these fleeting flashes of light fit into the broader puzzle of Earths atmospheric processes.
