The maintenance of the physiological function of the eye as a highly differentiated sensory organ relies on tight metabolic regulation. The intramitochondrial tricarboxylic acid (TCA) cycle serves as a core pathway for ocular energy metabolism, providing essential metabolic substrates and reducing equivalents for corneal homeostasis and retinal phototransmission. However, significant scientific questions remain. The question is, are there significant heterogeneities in energy utilization between different anatomical tissues of the eye? Furthermore, how does biological sex modulate the ocular metabolic profile through different biological pathways? Previous studies have mainly employed relative quantification to analyze metabolite abundance, and while reflecting trends, have…
Protein language models are artificial intelligence tools that help us design proteins with useful properties, including entirely new structures never before seen in nature. This technology has great potential to address global challenges, such as synthesizing enzymes that can absorb carbon dioxide from the atmosphere and building catalysts that can significantly reduce energy use and harmful waste byproducts in industrial processes. Even though many of these models are beginning to shape real-world decision-making in biotechnology, major challenges remain. Protein language models (pLMs) operate primarily as black boxes, making it difficult to understand their decision-making processes and determine whether their predictions…
Neurons and white blood cells differ greatly in shape, function, and location in the body. However, researchers at the University of São Paulo (USP) in Brazil found that certain genes were similarly dysregulated in both cell types in patients with depression. The findings not only confirm the systemic nature of depression, which has implications beyond mental health, but also pave the way for future blood tests that can identify the type and severity of depression. The study was published in the journal scientific report. This research was supported by FAPESP through four projects (18/18886-9, 24/21635-9, 23/07806-2, and 23/06086-6). We…
74,000 years ago, Earth experienced one of the most powerful volcanic disasters in the past 2.5 million years. The current Toba super-eruption centered in Indonesia caused devastating damage on an astonishing scale. The eruption was so huge that scientists believe it affected nearly every corner of the planet. For archaeologists studying ancient volcanic phenomena, one question stands out above all others. That is, how did humans survive? The Toba eruption was more than 10,000 times larger than the 1980 Mount St. Helens eruption, but our species held out. Toba super eruption changed the earth The eruption blew 672 cubic miles…
New Ontario data shows that pregnant doctors often take on more work during the first trimester and then take more variable and short parental leave, raising urgent questions about medical culture, workforce planning and gender equity in health care. Research: Physician work patterns during pregnancy, parental leave, and return to work. Image credit: Gorodenkoff / Shutterstock In a recent study published in JAMA network openresearchers examined physicians’ work patterns before, during, and after pregnancy. Background of workload and vacation for pregnant doctors Despite predictions that women will make up approximately 50 per cent of Canada’s physician workforce by 2030, pregnancy…
The new framework suggests that physical activity acts as an external tool that helps harmonize the way the brain processes negative experiences and aversive information. This study outlines how both single training and long-term exercise habits can shape specific cognitive pathways that support better emotional regulation. The study was published in the journal Mental Health and Physical Activity. When a person encounters upsetting information, the brain initiates a series of cognitive processes. This emotion production sequence typically includes four distinct stages: situation, attention, evaluation, and reaction. The initial situation provides the input and the brain’s attention system determines which elements…
WASHINGTON — The Supreme Court will leave women’s access to the widely used abortion pill until at least Thursday, while the justices consider whether to allow restrictions on the drug mifepristone. Justice Samuel Alito’s Monday order allows women seeking abortions to continue obtaining the pill at pharmacies or through the mail without having to visit a doctor in person. This prevents restrictions on mifepristone imposed by a federal appeals court from taking effect for the time being. The court is grappling with the latest abortion debate four years after a conservative majority overturned Roe v. Wade, effectively banning abortion altogether…
The EPA proposed Monday to allow data centers, power plants and other industrial facilities to begin certain construction work before obtaining the necessary federal aviation permits. The proposal is the latest development in the Trump administration’s efforts to jump-start new manufacturing and other industries, particularly artificial intelligence. EPA Administrator Lee Zeldin said the changes will speed up projects by eliminating red tape. “Today’s proposals are designed to provide solutions to problems that have underpinned America’s critical infrastructure and advance the frontiers of the next great technology,” he said in a statement. Any new facility that is identified as a major…
Recent research published in Aviation psychology and applied human factors suggest that flight instructor personality and school safety culture are strong predictors of on-duty safety behavior. The findings provide evidence that highly organized and responsible instructors are more likely to strictly follow safety protocols, especially when flight schools prioritize safety. These insights provide new ways for flight schools to hire and train instructors to reduce aviation accidents. Researchers Vivek Sharma and Meredith Carroll conducted this study to understand the human factors that influence safety during flight training. The National Transportation Safety Board recorded more than 1,600 accidents related to flight…
SALISBURY, Md. – A series of new court filings in the ongoing Salisbury PFAS contamination lawsuit against Perdue Farms sheds more light on where the company says the contamination comes from and who it believes is ultimately responsible.In a filing Friday, May 8, in U.S. District Court in Maryland and obtained by WBOC, Perdue asked a federal judge to allow third-party charges against companies associated with longtime fire technology specialists 3M and Johnson Controls. Perdue alleges that a fire extinguishing agent used at the Salisbury soybean processing agribusiness facility, made by 3M and delivered through a Johnson Controls system, contributed…
