North American bird populations are shrinking most rapidly in the very areas where they are still most abundant, according to a new study leveraging citizen science data for nearly 500 bird species. The findings reveal both urgent threats and potential opportunities for targeted conservation and recovery. Bird populations are experiencing steep declines globally, with North America losing more than 25% of all breeding birds since 1970. While long-term monitoring has revealed these troubling trends, effective conservation requires knowing where populations are declining most. However, this goal has been limited by the ...

In many countries, males are more likely than females to get sick and die from three common conditions, and less likely to get medical care, according to a new study by Angela Chang of the University of Southern Denmark, and colleagues, published May 1st in the open-access journal PLOS Medicine. Many health policies are the same for males and females, even though there is strong evidence that sex and gender can substantially influence a person’s health outcomes. In the new study, researchers gathered ...

Roses, long admired for their beauty and symbolic richness, owe their iconic petal shape to a mechanical process that has remained largely mysterious—until now. According to a new study, the pointed cusps that gradually form at the edge of rose petals as they grow are shaped not by the well-known mechanics behind wavy leaves, but by a distinct geometric frustration called Mainardi-Codazzi-Peterson (MCP) incompatibility. According to the findings, this stress-focusing phenomenon not only sculpts the rose’s form but also feeds back to influence how the petal grows, offering new insights into the mechanics of nature, and potential inspiration for the design of bio-inspired ...

New findings challenge assumptions about species’ ability to persist under climate change. Following a nine-year study of over 100,000 individual Drummond's rockcress plants – a common plant found in mountains across North America – researchers reveal that climate change is outpacing natural gene flow, threatening population survival even within a broadly distributed plant species’ native range. The findings highlight the potential role of assisted gene flow in plant conservation. Climate change is rapidly altering where ...

Researchers have found a new ally in the fight against a serious liver disease: a symbiotic gut-dwelling fungus that produces a molecule shown to be capable of reversing disease progression in mice. The findings may inform future therapeutic approaches to treat metabolic dysfunction-associated steatohepatitis (MASH), a highly prevalent disease. Metabolic dysfunction–associated fatty liver disease (MAFLD) now affects roughly one in four adults worldwide, making it the most prevalent chronic liver condition and a pressing global health issue. The more severe ...

ITHACA, N.Y. —A groundbreaking study published today in Science reveals that North American bird populations are declining most severely in areas where they should be thriving.  Researchers from the Cornell Lab of Ornithology analyzed 36 million bird observations shared by birdwatchers to the Cornell Lab’s eBird program alongside multiple environmental variables derived from high-resolution satellite imagery for 495 bird species across North America from 2007 to 2021.  The team set out to develop reliable ...

The ‘cell of origin’ of the second most common lung cancer and the way that it becomes dominant in the lung have been discovered, in a new study in mice and humans from researchers at UCL, the Wellcome Sanger Institute and the University of Cambridge. The study, published in Science, found that a population of basal cells1 found in the trachea (windpipe) outcompetes other cell types and becomes dominant, eventually invading and occupying large areas of the lung. It is from these cells, ...

DETROIT – The number of people suffering from osteoarthritis is expected to top 1 billion by 2050. The biggest risk factor for the prevalent, often painful, chronic joint disease is aging. And like aging, there is currently no way to stop it. A discovery by scientists at Henry Ford Health + Michigan State University Health Sciences could pave the way for new breakthroughs in detecting and treating the disease. Their findings were recently published in Nature Communications. “Our hope is that this discovery will one day allow doctors to catch ...

Some public transit shelter designs can actually do more harm than good when it comes to shielding from summer temperatures, according to a study led by UTHealth Houston. The research was published in Transportation Research Part D: Transport and Environment. Public transit can be more affordable, healthy, and safe than commuting by car. Research supports that public transportation is also better for the environment by limiting emissions and air pollution. According to the American Public Transportation Association, more than two-thirds of transit users in the U.S. walk to the transit stop or station. However, during ...

Washington, D.C. – May 1, 2025 – New findings from multiple studies demonstrate that glucagon-like peptide-1 receptor agonists (GLP-1RAs), a class of medications used to treat type 2 diabetes, play a significant role in improving cardiovascular outcomes like heart failure (HF), acute myocardial infarction (AMI), peripheral artery disease (PAD), and ST-elevation myocardial infarction (STEMI). The data were presented today at the Society for Cardiovascular Angiography & Interventions ...

Washington, D.C. – May 1, 2025 – New data highlights juxtaposing trends in serious obesity-related cardiovascular events. A recent study details the obesity paradox in patients with critical limb ischemia (CLI), demonstrating lower mortality in patients with obesity by 50% compared to non-obese patients. Whereas separate data suggests there is a rising mortality rate of almost four-fold in premature cardiac arrest and acute myocardial infarction (AMI) patients with obesity, specifically in racial minorities and rural communities. The data were presented today at the Society for Cardiovascular Angiography & Interventions (SCAI) 2025 ...

Santa Cruz, Calif.—Animal research on biomusicality, which looks at whether different species are capable of  behaving in ways that show they recognize aspects of music, including rhythm and beat, remains a tantalizing field at the intersection of biology and psychology. Now, the highly trained California sea lion at UC Santa Cruz who achieved global fame for her ability to bob her head to a beat is finally back: starring in a new study that shows her rhythm is just as precise—if not better—than humans. Ronan first shimmied onto the world stage in 2013, when researchers at the university’s Long Marine Laboratory reported that, not only ...

CAMBRIDGE, MA -- The composition of bacterial populations living on our faces plays a significant role in the development of acne and other skin conditions such as eczema. Two species of bacteria predominate in most people, but how they interact with each other, and how those interactions may contribute to disease, has been difficult to study. MIT researchers have now revealed the dynamics of those interactions in more detail than previously possible, shedding light on when and how new bacterial strains emerge on the skin of the face. Their findings could help guide the development of new treatments for ...
