Scientists discover a hunger ‘switchboard’ in the brain – and may soon be able to turn your appetite ‘on’ or ‘off’ Researchers at the University of Arizona discovered a complex network of brain regions that communicate to tell us when we are hungry or sated They found that they could use chemicals to turn ‘off’

Efforts to support older people during extreme heat should focus on those who lack independence or have pre-existing health issues, according to an expert from the University of Warwick. New research shows that having locations where older people can keep cool plays a key role in reducing their vulnerability to extreme heat, but that older

Long-term exposure to air pollution has been previously associated with a higher risk of hypertension in high-income countries, where air pollution levels are generally lower than in low- and middle-income countries. A team led by the Barcelona Institute for Global Health (ISGlobal), an institution supported by “la Caixa,” set out to study this association in

Women exposed to a ‘gender-bending’ chemical found in some anti-bacterial soaps and toothpastes ‘are more likely to break their bones’ Triclosan is used in products such as toothpaste, mouthwash and cosmetics A study found women with higher levels in the urine had weaker bones Researchers said triclosan could be a risk for the bone disease

The strongest genetic risk factor for Alzheimer’s disease is the apolipoprotein E type 4 allele (ApoE ε4). Research presented by Manish Paranjpe at the 2019 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging (SNMMI) used positron emission tomography (PET) to show that women who are ApoE ε4 carriers and already experiencing mild

A new study has found that variability in night-to-night sleep time and reduced sleep quality adversely affect the ability of older adults to recall information about past events. The study also found unexpected racial differences in the type of sleep patterns tied to lower memory performance across both younger and older African American research participants.

Japanese scientists at Tokyo University of Agriculture and Technology (TUAT), Teikyo University of Science, and Juntendo University have found—in animal studies—a close relationship between vortex flow and pressure differences in the ventricles, or lower chambers, of the heart. The new information could inform the development of new markers for cardiovascular dysfunction that can lead to

Starting this summer, physicians at UC Davis Health will be able to use a powerful new scanner that can render detailed, 3-D images of the inner workings of the entire human body in as little as one minute, the creators of the device announced recently. UCD researchers Ramsey Badawi and Simon Cherry said the sophisticated

When it comes to keeping track of prescribed medications between clinic visits, many patients rely on printed medication lists automatically generated from electronic health records (EHRs). An examination of the EHRs of a cohort of ophthalmology patients revealed that one-third had at least one discrepancy between the medications discussed in the clinician’s notes and those

Researchers at Indiana University School of Medicine have discovered how a dangerous parasite maintains a steady supply of nutrients while replicating inside of its host cell: it calls for delivery. Toxoplasma gondii is a single-celled parasite capable of infecting any animal, including humans. Up to one-third of infections in people happen through contact with cat

“Girl” singer Maren Morris is showing the world she’s all woman in her new photoshoot in Playboy magazine. The country star posed topless for a June 2019 feature for the iconic magazine. In a series of nearly nude photos, Morris strikes powerful, sexy and playful looks while wearing country standards like cowboy boots and hats.

Earlier research has shown that growing up on a farm with animals may as much as half the risk of asthma and allergies. The protective effect is thought to be attributable to the diverse microbial exposures encountered on farms. “We discovered that the presence of farm-like microbiota in an early-life home seemed to protect from

University Medical Center hosts first-ever honor walk for teen organ donor Raw video: University Medical Center of Southern Nevada hosted its first-ever honor walk for Michael Sigler, an 18-year-old organ donor who was killed in a motorcycle crash. Hundreds lined the halls of a Nevada hospital as an 18-year-old boy who died in a motorcycle accident

Infectious proteins called prions cause a group of related, fatal and incurable neurodegenerative disorders, including bovine spongiform encephalopathy or Mad Cow disease and Creutzfeldt-Jakob disease, both of which affect humans. Chronic wasting disease or CWD, also caused by prions, has reached the point of a global epidemic among deer, elk and members of the deer

If you’ve ever come out of a bad relationship and decided you need to date someone different from your usual “type,” you’re not alone. However, new research by social psychologists at the University of Toronto (U of T) suggests that might be easier said than done. A study published today in Proceedings of the National

Most neurons have many branching extensions called dendrites that receive input from thousands of other neurons. Dendrites aren’t just passive information-carriers, however. According to a new study from MIT, they appear to play a surprisingly large role in neurons’ ability to translate incoming signals into electrical activity. Neuroscientists had previously suspected that dendrites might be

Midway through the morning session of Mental Health First Aid, a course at the Mental Health Center of Denver, my instructor asks me to turn to one of my tablemates, look them in the eye, and ask a simple question: “Are you thinking about killing yourself?” Not “hurting yourself,” because the semantics will work against

Even though most of us get a baseline education in nutrition — or at least an outdated version of the food pyramid — in school, it’s easy to go through life without a clear understanding of what is and isn’t healthy. It doesn’t help that the clever marketing of food corporations looking to make more

(HealthDay)—Older adults with impaired vision are at increased risk for perceived discrimination, which in turn is associated with poorer emotional well-being, according to a study published online May 30 in JAMA Ophthalmology. Sarah E. Jackson, Ph.D., from University College London, and colleagues analyzed data from 7,677 participants (mean age, 66.7 years; 52.4 percent female) in

(HealthDay)—The U.S. pathologist workforce decreased in both absolute and population-adjusted numbers from 2007 to 2017, according to a study published online May 31 in JAMA Network Open. David M. Metter, M.D., from the University of Texas Southwestern Medical Center in Dallas, and colleagues used data from the American Association of Medical Colleges Center for Workforce
