CORVALLIS, Ore. – Firsthand observations of a wolf hunting and killing a harbor seal and a group of wolves hunting and consuming a sea otter on Alaska’s Katmai coast have led scientists to reconsider assumptions about wolf hunting behavior. Wolves have previously been observed consuming sea otter carcasses, but how they obtain these and the frequency of scavenging versus hunting marine prey is largely unknown. Scientists at Oregon State University, the National Park Service and Alaska Department of Fish and Game are beginning to change that with a paper just published ...

If anesthesiologists had a rigorous means to manage dosing, they could deliver less medicine, maintaining exactly the right depth of unconsciousness while reducing postoperative cognitive side effects in vulnerable groups like the elderly. But with myriad responsibilities for keeping anesthetized patients alive and stable, as well as maintaining their profoundly unconscious state, anesthesiologists don’t have the time without the technology. To solve the problem, researchers at The Picower Institute for Learning and Memory ...

  Social media can incubate communities that are so resilient that even banning them from the platform cannot destroy them. Michele Starnini and colleagues studied two online communities on the social media site Reddit: the far-right conspiracy theory subreddit GreatAwakening, which was banned in 2018, and the hate-speech subreddit FatPeopleHate, banned in 2015. Both communities decided amongst themselves to move to Voat, an unmoderated Reddit clone designed to serve those banned by Reddit. The authors estimate that less than 20% of FatPeopleHate users migrated to Voat, while more than 70% of GreatAwakening users migrated to the new platform. This result suggests that members ...

A pioneering study at Umeå University, Sweden, has unveiled that the 3D organization of DNA can influence the progression of the aggressive brain tumour known as glioblastoma. Having identified the factors that glioblastoma uses to respond to neurons by growing and spreading, this discovery paves the way for further research into new treatments for brain tumours. "We have now identified the most important factors behind how the tumour responds to nerve cells, thus becoming more dangerous. These findings offer hope in our long-term battle against this difficult-to-treat ...

The planet’s demand for salt comes at a cost to the environment and human health, according to a new scientific review led by University of Maryland Geology Professor Sujay Kaushal. Published in the journal Nature Reviews Earth & Environment, the paper revealed that human activities are making Earth’s air, soil and freshwater saltier, which could pose an “existential threat” if current trends continue. Geologic and hydrologic processes bring salts to Earth’s surface over time, but human activities such as mining and land development are rapidly accelerating the natural “salt ...

Getting readers of a news story interested in numbers can be a challenge. But the benefits of engaging readers in data can lead to a better understanding, preventing misinformation and misrepresentation in the news. New research by Haiyan Jia, assistant professor in the Department of Journalism and Communication and the Data X Initiative at Lehigh University, and S. Shyam Sundar, the James P. Jimirro Professor of Media Effects at Penn State University, explored different ways journalists present data and recommend a method using an interactive visualization.   Inspired by exemplification theory, Jia wanted to see the persuasive effect data could have and whether ...

A new artificial intelligence (AI) model, developed by the University of Surrey, could help the UK's telecommunications network save up to 76% in network resources compared to the market's most robust Open Radio Access Network (O-RAN) system – and improve the environmental sustainability of mobile networks by using less energy.   In a study published in the journal IEEE Transactions on Network Service Management, Surrey researchers detail how it is possible to save bandwidth by mathematically modelling the network and using AI to find the best ...

Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets out of orbit and wreak havoc on their climates. Jupiter, by far the biggest planet in our solar system, plays an important protective role. Its enormous gravitational field deflects comets and asteroids that might otherwise hit Earth, helping create a stable environment for life. However, giant planets elsewhere in the universe do not necessarily protect life on their smaller, rocky planet neighbors.  A new Astronomical Journal paper details how the pull of massive ...

Toronto, ON — New research published earlier this month in the International Journal of Aging and Human Development has highlighted the significant health disparities among older adults with a General Education Development (GED) certificate compared to their peers with a high school diploma. Researchers from the University of Toronto examined health outcomes among approximately 400,000 older adults from the American Community Survey, a representative sample of community-dwelling and institutionalized older Americans. They found that ...

Drugs to treat common infections in children and babies are no longer effective in large parts of the world, due to high rates of antibiotic resistance. The University of Sydney led study found many antibiotics recommended by the World Health Organization (WHO) had less than 50 percent effectiveness in treating childhood infections such as pneumonia, sepsis (bloodstream infections) and meningitis. The findings show global guidelines on antibiotic use are outdated and need updates. The most seriously ...

Approximately 80% of Apple's latest iPhone 15 pre-orders in Korea fall within the age group of 20s and 30s.

Australasia has likely overlooked a pollination crisis, according to new research published today in the journal Ecology and Evolution. The research, led by Macquarie University, also underscores a pressing need for intervention to avoid biodiversity loss and long-term food insecurity in the region. The authors analysed thousands of research papers on human-induced pollinator decline globally, and found despite only a tiny portion mentioning Australasia, the causes of pollinator decline in the northern hemisphere were mirrored in this region. Research in Europe and North America finds threats that include ...

New research from a consortium of quantum physicists, led by Trinity College Dublin’s Dr Mark Mitchison, shows that imperfect timekeeping places a fundamental limit to quantum computers and their applications. The team claims that even tiny timing errors add up to place a significant impact on any large-scale algorithm, posing another problem that must eventually be solved if quantum computers are to fulfil the lofty aspirations that society has for them.  It is difficult to imagine modern life without clocks to help organise our daily schedules; with a digital clock in every person’s smartphone or watch, we ...

ITHACA, N.Y. –Micron-size microplastic debris can be carried by the jet stream across oceans and continents, and their shape plays a crucial role in how far they travel. A Cornell University collaboration has developed a model to simulate the atmospheric transport of microplastic fibers and shows that flat fibers travel farther in the lower atmosphere, and are more prevalent, than spherical fibers. Previous studies assumed these fibers to be spherical. The modeling has the potential to help scientists determine the sources of the pervasive waste – which could inform policy efforts to reduce it. The ...

Colorectal cancer screening is widely recommended for adults ages 45 to 75 with an average risk of developing the disease. However, many people don’t realize that the benefits of screening for this type of cancer aren’t always the same for older adults. “While many clinicians simply follow guideline recommendations for colon cancer screening in adults within this age range, this isn’t always the best approach,” said Sameer Saini, M.D., M.S., who is a gastroenterologist at both Michigan Medicine and the Lieutenant Colonel Charles S. Kettles VA Medical Center and is as a health ...

NASA’s James Webb Space Telescope has gazed at the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus.
