LHS 3844b is an exoplanet slightly larger than Earth orbiting the red dwarf star LHS 3884, 48.5 light-years from our solar system. Unlike Earth, it has fixed tidal forces and rotates around its axis in exactly the same amount of time it takes to orbit a star. As a result, one hemisphere is constantly exposed to scorching sunlight, while the other remains in eternal darkness, cold enough to approach absolute zero (zero Kelvin). At first glance, these extreme environments seem completely inhospitable. Daytime temperatures can reach around 1,000 to 2,000 Kelvin, but the night side is so cold that particle…
Mayo Clinic is being sued over allegations that a former research director was retaliated against and ultimately fired for raising concerns about the Rochester, Minn.-based health system’s artificial intelligence practices. The lawsuit was filed Monday in U.S. District Court for the District of Minnesota by Tracy Tamiko Eto, represented by HKM employment attorneys Artur Davis and Rebecca Rojas. The lawsuit alleges that Mayo Clinic violated the retaliation provisions of the False Claims Act, the Americans with Disabilities Act (ADA), and the Family and Medical Leave Act. According to the complaint, Eto joined Mayo Clinic in December 2023 as director of…
How the body’s stress system functions before a traumatic event may help determine who develops persistent post-traumatic stress symptoms afterward, according to a study published in the journal Translational Psychiatry. Researchers have found that childhood adversity, pre-traumatic stress hormone levels, and changes in a small area of the brain called the hypothalamus work together to influence how people respond to trauma. Although many people experience traumatic events during their lifetime, not everyone develops post-traumatic stress disorder (PTSD). Previous research has shown that adverse childhood experiences, such as abuse, neglect, and family dysfunction, increase the risk of PTSD later in life.…
The success of mRNA vaccines against SARS-CoV-2 during the COVID-19 pandemic has transformed vaccine science. Today, the same Nobel Prize-winning technology is being applied in the fight against cancer, with experimental mRNA vaccines already being tested against melanoma, small cell lung cancer, bladder cancer, and several other cancers. Researchers hope that these vaccines could eventually provide powerful new ways to prevent and treat the disease. A new study from Washington University School of Medicine in St. Louis reveals an unexpected feature of how these cancer vaccines work. Scientists have discovered in experiments on mice that mRNA cancer vaccines remain highly…
Over the past two weeks, British Columbians have revisited the deadly heat wave that blanketed the province and much of western North America in 2021. Announcements, events, and more from Tyee and select partners Indigenous brilliance shines in the Knowledge Network The B.C.-based public broadcaster is celebrating Indigenous History Month with 12 powerful films and original series. Now that a “Super El Niño” weather pattern has developed in the Pacific Ocean, heralding the end of a hotter and drier-than-usual summer in the region, the question is whether we are prepared for similar extreme temperatures. The answer is no, according to…
Recent research published in journals psychiatric services Our findings suggest that simple suicide prevention programs are being successfully implemented for at-risk veterans across the Veterans Health Administration. This study provides evidence that patients at high risk for suicide are more likely to complete these safety plans, especially if hospital policy requires them. These findings provide insights that can help health systems improve suicide prevention strategies and ensure more equitable care for all patients. Suicide rates in the United States have increased by approximately 30% over the past 20 years. This growing public health crisis has led medical professionals to seek…
An innovative new study from UCSF’s Neuroscape Research Center and consumer electronics giant Samsung aims to understand decade-to-decade changes in brain health. The Neuroscape Technology for Aging Health – Digital Approaches (TAH-DA) longitudinal study aims to use Samsung’s wearable technology to identify biometric predictors of cognitive decline over a one-year period. Samsung collaborates with leading institutions to foster innovation and innovative health research, exploring new health technologies and new norms of health. The TAH-DA study is another example of Samsung’s commitment to understanding the unique relationship between the brain and health. This research is part of Samsung’s Open Innovation Initiative,…
Researchers at the University of Texas MD Anderson Cancer Center have identified six genetic signatures in microscopic colorectal cancer (CRC) liver metastases that may help predict recurrence after treatment. This finding suggests that these small, often undetectable tumor deposits may serve as tissue-based markers of residual cancer cells, recurrence risk, and chemotherapy resistance. Published today is cancer cellsa comprehensive spatial analysis of CRC metastases used advanced genomic techniques to uncover insights into how micrometastases evolve, evade the immune system, and persist after treatment. The study was co-led by Dipen Mal, MD, professor of anatomic pathology. Scott Kopetz, MD, Professor of…
Researchers at the University of Gothenburg have identified a key protein that allows the virus that causes genital herpes to enter the nervous system. The findings, made in experiments on mice, could pave the way for future vaccines against the disease. Genital herpes is primarily transmitted through sexual contact and is one of the most common viral infections in the world. The HSV-2 virus establishes a lifelong infection by entering nerve cells, where it remains dormant for long periods and later reactivates. Many people who carry the virus do not experience any noticeable symptoms, but some people experience recurring symptoms…
Anxiety disorders affect more than 300 million people worldwide. Several brain regions are thought to be associated with anxiety, but little is known about how these regions are related. By investigating these connections, scientists at St. Jude Children’s Research Hospital revealed that epinephrine-producing C1 neurons are regulators of fear and anxiety in mice. They found that although the activity of these neurons typically increases briefly during times of stress, prolonged activity increases anxiety, which can last for days. Inhibiting C1 neurons reduced anxiety-like behavior, suggesting that these neurons may be worth investigating as therapeutic targets for anxiety disorders. The survey…
