BOSTON - Automated emails and letters that provide personalized feedback related to cafeteria purchases at work may help employees make healthier food choices. That's the conclusion of a new study that was led by investigators at Massachusetts General Hospital (MGH) and is published in JAMA Network Open.
RUDN University chemists and their colleagues from Novosibirsk State University, Novosibirsk Institute of Organic Chemistry and The State Research Center of Virology and Biotechnology VECTOR have obtained a new class of compounds that inhibit the replication of the deadly Hantaan virus that affects blood vessels and internal organs of humans. The resulting substances were 5 times more effective than existing antiviral drugs. The results have been published Bioorganic & Medicinal Chemistry Letters.
Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their missions.
A new study from researchers at Johns Hopkins Bloomberg School of Public Health and colleagues suggests a slowdown in the use of convalescent plasma to treat hospitalized COVID-19 patients led to a higher COVID-19 mortality during a critical period during this past winter's surge.
LA JOLLA--(June 7, 2021) Type 1 diabetes, which arises when the pancreas doesn't create enough insulin to control levels of glucose in the blood, is a disease that currently has no cure and is difficult for most patients to manage. Scientists at the Salk Institute are developing a promising approach for treating it: using stem cells to create insulin-producing cells (called beta cells) that could replace nonfunctional pancreatic cells.

Youth brain activation data from the largest longitudinal neuroimaging study to date provides valuable new information on the cognitive processes and brain systems that underlie adolescent development and might contribute to mental and physical health challenges in adulthood. The study published today online in Nature Neuroscience.
To investigate factors that can jeopardize pregnancy success in cattle, researchers at the University of São Paulo (USP) in Brazil used a kind of chip to mimic the environment of the endometrium, the tissue that lines the inside of the uterus.
The emerald ash borer, an invasive beetle native to Southeast Asia, threatens the entire ash tree population in North America and has already changed forested landscapes and caused tens of billions of dollars in lost revenue to the ash sawtimber industry since it arrived in the United States in the 1990s. Despite the devastating impact the beetle has had on forests in the eastern and midwestern parts of the U.S., climate change will have a much larger and widespread impact on these landscapes through the end of the century, according to researchers.
An experimental, lab-made antibody can completely prevent nonhuman primates from being infected with the monkey form of HIV, new research published in Nature Communications shows.
The results will inform a future human clinical trial evaluating leronlimab as a potential pre-exposure prophylaxis, or PrEP, therapy to prevent human infection from the virus that causes AIDS.
Heart attacks and strokes -- the leading causes of death in human beings -- are fundamentally blood clots of the heart and brain. Better understanding how the blood-clotting process works and how to accelerate or slow down clotting, depending on the medical need, could save lives.
New research by the Georgia Institute of Technology and Emory University published in the journal Biomaterials sheds new light on the mechanics and physics of blood clotting through modeling the dynamics at play during a still poorly understood phase of blood clotting called clot contraction.
The concrete world that surrounds us owes its shape and durability to chemical reactions that start when ordinary Portland cement is mixed with water. Now, MIT scientists have demonstrated a way to watch these reactions under real-world conditions, an advance that may help researchers find ways to make concrete more sustainable.
A new technology could dramatically improve the safety of lithium-ion batteries that operate with gas electrolytes at ultra-low temperatures. Nanoengineers at the University of California San Diego developed a separator—the part of the battery that serves as a barrier between the anode and cathode—that keeps the gas-based electrolytes in these batteries from vaporizing. This new separator could, in turn, help prevent the buildup of pressure inside the battery that leads to swelling and explosions.
Citizen opposition to COVID-19 vaccination has emerged across the globe, prompting pushes for mandatory vaccination policies. But a new study based on evidence from Germany and on a model of the dynamic nature of people's resistance to COVID-19 vaccination sounds an alarm: mandating vaccination could have a substantial negative impact on voluntary compliance.
Brazilian researchers have simultaneously demonstrated the mechanism linking high blood pressure to elevated intracranial pressure, validated a non-invasive intracranial pressure monitoring method, and proposed a treatment for high blood pressure that does not affect intracranial hypertension.
