Petaluma, CA--Newly published research by Petaluma-based non-profit, Point Blue Conservation Science, shows how Adélie penguins within the Ross Sea, Antarctica use sea ice in their annual migrations. The results were published in the journal Ecology, a publication of the Ecological Society of America.  Adélie penguins, though flightless, can undertake extraordinary migrations like their flying relatives, traveling thousands of kilometers out to sea from their on-land breeding colonies in Antarctica, tracking daylight and food during the long Antarctic winter. Many other species are known to use wind ...

For the first time, researchers have analysed the impact of antibiotic use on the rise of treatment-resistant bacteria over the last 20 years in the UK and Norway. They show that while the increase in drug use has amplified the spread of superbugs, it is not the only driver. Researchers from the Wellcome Sanger Institute, the University of Oslo, the University of Cambridge, and collaborators, conducted a high-resolution genetic comparison of bacteria. They compared over 700 new blood samples with nearly 5,000 ...

(MEMPHIS, Tenn. – January 11, 2024) Data from the St. Jude lifetime cohort study (St. Jude LIFE) revealed that two common biomarkers of cardiac function and damage could better predict cardiomyopathy within five years than routine clinical evaluations in high-risk, asymptomatic childhood cancer survivors. Early detection through screening using these two biomarkers may lead to earlier treatment to prevent and protect against further heart damage. The findings were published today in the Journal of Clinical Oncology.    Cardiomyopathy is often asymptomatic at onset and thus “invisible” to routine clinical evaluations. St. Jude ...

New UC Davis research shows that men with an FMR1 premutation who experienced reduced executive function were at higher likelihood of developing fragile X-associated tremor/ataxia syndrome (FXTAS). FXTAS is a progressive genetic condition that causes movement issues and cognitive decline. These findings, published in the journal Movement Disorders, could help clinicians determine which premutation carriers will eventually develop FXTAS. “There's converging evidence that the premutation is affecting certain circuits in the brain ...

Human activity, from burning fossil fuels and fireplaces to the contaminated dust produced by mining, alters Earth’s atmosphere in countless ways. Records of these impacts over time are preserved in everlasting polar ice that serves as a sort of time capsule, allowing scientists and historians to link Earth’s history with that of human societies. In a new study, ice cores from Antartica show that lead and other toxic heavy metals linked to mining activities polluted the Southern Hemisphere as early as the 13th century.  “Seeing evidence that early Andean ...

    Images     An insight into preventing perovskite semiconductors from degrading quickly, discovered at the University of Michigan, could help enable solar cells estimated to be two to four times cheaper than today's thin-film solar panels.    Perovskites may also be combined with the silicon-based semiconductors that are prevalent in today's solar panels to create "tandem" solar cells that could surpass the maximum theoretical efficiency of silicon solar cells.   "Silicon solar cells are great because they are very efficient and can last for a very long time, but the high efficiency comes with a high cost," ...

Sharks have persisted as powerful ocean predators for more than 400 million years. They survived five mass extinctions, diversifying into an amazing variety of forms and lifestyles. But this ancient lineage is now among the world's most threatened species groups due to overexploitation in poorly regulated fisheries and the proliferation of wasteful finning practices. Governments around the world have introduced a host of regulations aimed at reducing shark catch and finning, the latter of which typically sees valuable shark fins retained for sale while carcasses are discarded at sea. But until ...

A dense system of pre-Hispanic urban centers, characterized by constructed platforms and plazas and connected by large, straight roads, has been discovered in the upper Amazon, according to a new study. The research, based on more than 20 years of interdisciplinary research, suggests that this original 2500-year-old society constitutes the earliest and largest low-density agrarian urbanism documented in the Amazon thus far. Such extensive early development in the Upper Amazon resembles similar Maya urban systems in Central America. ...

Clinical prediction models for schizophrenia treatment outcomes that work well within the trials from which they were developed fail to generalize to future trials, according to a new study. “The findings not only highlight the necessity for more stringent methodological standards for machine learning approaches but also require reexamination of the practical challenges that precision medicine is facing,” writes Frederike Petzschner in a related Perspective. Despite receiving the same treatments for the same afflictions, some patients get better while others show no improvement. Precision medicine approaches seek to address this problem by providing tailored treatments for individual ...

Despite widespread legislation and fishing regulations aimed at reducing wasteful shark finning practices, global shark fishing mortality is still on the rise, researchers report. The findings suggest that improved regulations are needed to reverse the continued overexploitation of these species. Over the last several decades, sharks have been increasingly recognized as some of the planet’s most threatened wildlife. Increasing shark mortality has been driven in part by overfishing – large numbers of sharks are often captured as bycatch in tuna ...

A comprehensive analysis of tree species’ conservation statuses across Atlantic Forest trees reveals high extinction risks. According to the report, roughly two-thirds of the 4950 tree species living in this biodiversity hotspot are threatened with extinction. This includes 82% of endemic species, which have quite limited geographic ranges. Based on these findings, the authors suggest that the conservation status of tropical forests worldwide may be worse than previously believed. Conservation efforts and decisions often ...

With human retinas grown in a petri dish, researchers discovered how an offshoot of vitamin A generates the specialized cells that enable people to see millions of colors, an ability that dogs, cats, and other mammals do not possess. “These retinal organoids allowed us for the first time to study this very human-specific trait,” said author Robert Johnston, an associate professor of biology. “It’s a huge question about what makes us human, what makes us different.” The findings, published in PLOS Biology, increase understanding of color ...
