BOSTON - Current guidelines recommend stopping cervical cancer screening at age 65, but women over age 65 make up over one in five new cervical cancer diagnoses, and are twice as likely to die after a cervical cancer diagnosis compared to younger women. New research from Boston Medical Center found that fewer than one in three women aged 64 to 66 met the criteria to discontinue cervical cancer screening while looking at patients with both private insurance and from a safety-net hospital setting.
GAINESVILLE, Fla. --- A more reliable way of estimating the size of megalodon shows the extinct shark may have been bigger than previously thought, measuring up to 65 feet, nearly the length of two school buses. Earlier studies had ball-parked the massive predator at about 50 to 60 feet long.
The revised estimate is the result of new equations based on the width of megalodon's teeth - and began with a high school lesson that went awry.
In the quest for healthy aging and longer lifespan, Danish researchers at the University of Southern Denmark have collaborated with Swedish researchers at Karolinska Institutet to explore the anti-aging effects of football and team handball training in women.
Climate change and social inequality are two pressing issues that often overlap. A new study led by Princeton researchers offers a roadmap for cities to address inequalities in energy use by providing fine-grained methods for measuring both income and racial disparities in energy use intensity. Energy use intensity, the amount of energy used per unit floor area, is often used as a proxy for assessing the efficiency of buildings and the upgrades they receive over time.
High blood pressure, or hypertension, is the leading modifiable risk factor for cardiovascular diseases and premature death worldwide. And key to treating patients with conditions ranging from chest pain to stroke is understanding the intricacies of how the cells around arteries and other blood vessels work to control blood pressure. While the importance of metals like potassium and calcium in this process are known, a new discovery about a critical and underappreciated role of another metal - zinc - offers a potential new pathway for therapies to treat hypertension.
A study conducted by a group of Brazilian researchers contributes to a deeper understanding of the molecular basis for schizophrenia, and potentially to the development of more specific and effective treatments for the disease. The medications currently available on the market act generically on the brain and can have severe adverse side effects.
In those with fatty liver disease, a person’s fat goes to their liver instead of their fat tissue, either because of an absence of fat depots, which is seen in the rare genetic disease lipodystrophy, or because the depots are too full, which is seen in people with obesity.
One third of these people will go on to develop nonalcoholic steatohepatitis, or NASH - an advanced form of fatty liver disease brought on by progressive inflammation and scarring in the organ.
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.
