New research led by a Florida State University professor shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production. Warmer temperatures cause lower hatchling success and a greater percentage of female turtles, both of which can disrupt the viability of a species. Sand temperatures at sea turtle nesting sites globally are projected to increase by about 0.6 degrees Celsius to ...

Suicide and mental health distress disproportionately affect veterans in the United States. According to a report from the Substance Abuse and Mental Health Services Administration, more than 5 million veterans suffered from these adverse behavioral health issues in 2020. That same year, after adjusting for age and sex differences in the population, the U.S. Department of Veterans Affairs (VA) estimated that veterans were 57.3 percent more likely to commit suicide than non-veterans. While the Veterans ...

The incidence of thyroid cancer in São Paulo State, part of Brazil’s relatively developed Southeast region, varies considerably according to socioeconomic status (education, poverty, wealth, income, segregation, mobility, and access to resources and services) and access to screening, but is highest in higher-income areas and the state capital. Mortality rates are similar across regions and income groups, however. These are the main findings of a study reported in the journal Endocrine Practice by researchers ...

Researchers at the University of Wisconsin–Madison and Academia Sinica of Taiwan have harnessed a combination of lab-grown cells to regenerate damaged heart muscle. The study, published in Circulation — which addresses major challenges of using heart muscle cells, called cardiomyocytes, grown from stem cells — takes a crucial step toward future clinical applications. Previous research has shown that transplanting cardiomyocytes made from induced pluripotent stem cells (iPSC) can replace muscle in the hearts of mammals. Researchers have struggled to bring the treatment to the clinic, in part because the implanted cells haven’t developed enough ...

A sunflower’s ability to track the sun east to west during the day, and to face east again before the next sunrise, relies on multiple types of photoresponses, according to a new study publishing October 31st in the open access journal PLOS Biology by Stacey Harmer and colleagues at the University of California Davis, US. The results deepen the understanding of this well-known plant behavior, and upend previous assumptions about its dependence on a canonical light-dependent response pathway. Because plants are ...

Order wine at a fancy restaurant, and the sommelier might describe its aroma as having notes of citrus, tropical fruit, or flowers. Yet, when you take a whiff, it might just smell like … wine. How can wine connoisseurs pick out such similar scents? Cold Spring Harbor Laboratory (CSHL) Associate Professor Saket Navlakha and Salk Institute researcher Shyam Srinivasan may have the answer. They have found that certain neurons allow fruit flies and mice to tell apart distinct smells. The team ...

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers “see” the sun to follow it? New work from plant biologists at the University of California, Davis, published Oct. 31 in PLOS Biology, shows that they use a different, novel mechanism from that previously thought.  “This was a total surprise for us,” said Stacey Harmer, professor of plant biology at UC Davis and senior author on the paper.  Most plants show phototropism – the ability to grow toward a ...

URBANA, Ill. — A team of animal scientists from the University of Illinois Urbana-Champaign is set to deliver a potential game changer for subsistence farmers in Tanzania: cows that produce up to 20 times the milk of indigenous breeds.      The effort, published in Animal Frontiers, marries the milk-producing prowess of Holsteins and Jerseys with the heat, drought, and disease-resistance of Gyrs, an indigenous cattle breed common in tropical countries. Five generations of crosses result in cattle capable of ...

CHAPEL HILL, N.C. – The lungs were once at the forefront of SARS-Cov-2 research, but as reports of organ failure and other serious complications poured in, scientists set out to discover how and why the respiratory virus was causing serious damage to the body's major organs, including the lungs. An interdisciplinary COVID-19 International Research Team (COV-IRT), which includes UNC School of Medicine’s Jonathan C. Schisler, PhD, found that SARS-CoV-2 alters mitochondria on a genetic ...

Children and young people with attention deficit hyperactivity disorder (ADHD) use healthcare services twice as often in the two years before their diagnosis, a study by researchers at the University of Nottingham and King’s College London has found. The research, published today in the journal Archives of Disease in Childhood shows that children with the neurodevelopmental disorder are twice as likely to see their GP, go to hospital for an admission, and even have operations, compared to children without ADHD. The researchers say the results support the need for healthcare professionals to consider a potential diagnosis of ADHD in children who ...

In the late 1970s, the relationship between the c-Src gene and cancer was discovered. The first oncogene was identified. Since then, c-Src has been found to be overactivated in half of colon, liver, lung, breast, prostate and pancreatic tumors, but its function is not yet fully understood. CNIO researchers have now discovered that this oncogene is capable of 'self-activation', by means of a previously undescribed molecular mechanism. This finding has implications for the development of new drugs.   In ...

Philadelphia, October 31, 2023 – Heart attacks, or acute myocardial infarction (MI), are one of the leading causes of death worldwide. The newly released Canadian Cardiovascular Society Classification of Acute Myocardial Infarction (CCS-AMI) appearing in the Canadian Journal of Cardiology, published by Elsevier, presents a four-stage classification of heart attack based on heart muscle damage. This work by a group of noted experts has the potential to stratify risk more accurately in heart attack patients and lays the groundwork for development of new, injury-stage-specific and tissue ...

UNIVERSITY PARK, Pa. — Voice speed and interaction style may determine whether a user sees a digital assistant like Alexa or Siri as a helpful partner or something to control, according to a team led by Penn State researchers. The findings reveal insights into the parasocial, or one-sided, relationships that people can form with digital assistants, according to the researchers. They reported their findings in the Journal of Business Research. “We endow these digital assistants with personalities and human characteristics, and it impacts how we interact with the devices,” said Brett Christenson, assistant clinical professor of marketing at Penn State and first author ...

WASHINGTON, Oct. 31, 2023 – When COVID-19 began to spread across the globe, its effects were significantly pronounced on cruise ships. Indeed, compared to other population segments, cruise ship passengers became disproportionately infected and often, ironically, stranded on board to quarantine. That’s why focus has been directed at addressing the need for improved ventilation on cruise ships –  since dispersing fresh air in cabins and other enclosed spaces is critical for mitigating viral spread. In Physics of Fluids, by AIP Publishing, a group of researchers from Cyprus examined how ventilation can affect ...
