As Earth continues to warm, sea levels have risen at an accelerating rate – from 1.4 millimeters a year to 3.6 millimeters a year between 2000 and 2015. Flooding will inevitably worsen, particularly in low-lying coastal regions, where more than a billion people are estimated to live. Solutions are needed to protect homes, property and groundwater from flooding and the intrusion of saltwater. Seawalls and similar infrastructure are obvious options to protect against flooding. In fact, cities such as New York and San Franciso have already thrashed out potential plans with the Army Corps of Engineers that will heavily rely ...

Stroke is the No. 5 cause of death and a leading cause of disability in the U.S. A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. When that happens, part of the brain cannot get the blood and oxygen it needs, so ...

The 2024 Summer Olympics are in full swing. One of the marquee events is of course the marathon, a grueling test of fitness and athleticism.  When it comes to endurance running, humans are among the very top mammals in their athletic prowess. While we may not be the best sprinters in the animal kingdom, we can run steadily for long distances, even in hot weather. Our locomotor muscles are dominated by slow-twitch, fatigue-resistant fibers and our unique ability to sweat allows our bodies to effectively dissipate heat. Humans are so good at endurance running, it seems we were born to do it. But why? A theory of endurance In ...

Many people enrolled in Medicaid who require psychiatric care have difficulty accessing clinicians in a timely manner despite the higher need in this population, according to a study by researchers at Weill Cornell Medicine.

Nearly half of the nation’s National Cancer Institute (NCI)-designated cancer centers required universal masking in key clinical areas during the winter 2023-2024 COVID-19 surge, according to a study by Tulane University researchers. Overall, 41.8% of these 67 centers required some universal masking, according to the study, which published in JAMA Network Open. Further, 12 NCI-designated centers (18%) required universal masking in all areas. Masking policies were even more common in northeastern states and in centers with longer NCI designation, more funding and higher care rankings. Those with cancer face higher risks from COVID-19 ...

Proteins are constantly performing a kind of dance. They move and contort their bodies to fulfill specific functions inside our bodies. The NMDAR protein executes an especially hard dance routine in our brains. One wrong step can lead to a range of neurological disorders. NMDAR binds to the neurotransmitter, glutamate, and another compound, glycine. These bindings control NMDAR’s dance steps. When their routine is over, the NMDAR opens. This open ion channel generates electrical signals critical for cognitive functions like memory. The problem is that scientists couldn’t figure out the last step in NMDAR’s routine—until ...

At any given time, over 10 trillion microbes call our guts their home. From breaking down nutrients in our food to strengthening our immunity against pathogens, these microbes play an essential role in how we interact with the world. This includes – as shown in a new study by EMBL researchers and collaborators at the University of Split, Croatia – the way the body responds to carcinogens and develops cancer.  Carcinogens are chemicals that can cause ordinary cells to transform into cancer ...

BOSTON– A cross-representative survey of adults in the United States showed decreasing levels of trust in physicians and hospitals during the COVID-19 pandemic—and the lower the trust, the less likely an individual was to get vaccinated against SARS-CoV-2 or influenza. The findings come from a survey study of more than 400,000 U.S. adults published in JAMA Network Open by a team co-led by investigators at Massachusetts General Hospital (MGH), a founding member of the Mass General Brigham healthcare system. “Trust in ...

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ability to walk, while cows can walk mere minutes after birth and run not long after. University of California San Diego researchers, using powerful new visualization technologies, now have a clear picture of why these two scenarios develop so differently. The results offer new insight into understanding muscle contraction in humans that may help in developing future treatments for muscular diseases. “In this study we set out to understand ...
