A new study provides fresh evidence that the decline in the capacity of brain cells to change, called “plasticity,” rather than a decline in total cell number may underlie some of the sensory and cognitive declines associated with normal brain aging. Scientists at MIT’s Picower Institute for Learning and memory show that inhibitory interneurons in

(HealthDay)—Systematic screening for anxiety, disability, and pain can increase psychological referral rates among pediatric patients with abdominal pain, according to a study published in the August issue of Pediatrics. Natoshia R. Cunningham, Ph.D., from the Cincinnati Children’s Hospital Medical Center, and colleagues implemented a screening process for patient-reported anxiety, functional disability, and pain levels in

(HealthDay)—From 2014 to 2017 there was an increase in tianeptine exposure calls reported by poison control centers to the National Poison Data System, and they mainly occurred among those aged 21 to 40 years, according to research published in the Aug. 3 issue of the U.S. Centers for Disease Control and Prevention’s Morbidity and Mortality

(HealthDay)—Serum 25-hydroxyvitamin D [25(OH)D] is independently and inversely associated with total cholesterol, low-density lipoprotein (LDL) cholesterol, and high-density lipoprotein (HDL) cholesterol in children, according to a study published in the July issue of the Journal of Clinical Endocrinology & Metabolism. Sonja Soininen, M.D., from the University of Eastern Finland in Kuopio, and colleagues examined the

Excessive body fat is associated with negative effects on female fertility and pregnancy. In mice, maternal obesity impairs proper development of egg precursor cells called oocytes. In a recent paper published in Molecular & Cellular Proteomics, Qiang Wang and colleagues at the State Key Laboratory of Reproductive Medicine in China describe the link between poor

Being the parent to a newborn is no joke, and Chip Gaines knows that firsthand. He and Joanna Gaines, his business partner and wife, now have five kids, including little Crew, who is just about 7 weeks old. So when he posted a silly picture on his Instagram about car seats, it was bound to

“Unsafe levels of a weed killer chemical in oat products,” cries a headline from CNN published earlier this week. The accompanying article cites a new report from the Environmental Working Group (EWG), a nonprofit advocacy organization, that revealed traces of glyphosate—the main ingredient in the pesticide Roundup—in several types of oat cereal, oatmeal, granola, and

While people with autism may avoid eye contact in one-on-one conversations, they may not avoid looking at people in photos, according to Penn State researchers. Krista Wilkinson, professor of communication sciences and disorders, said previously it was thought that people with autism had a hard time focusing on humans in photos, which could make it

Guided by glowing bacteria, researchers have devised an imaging technique that can diagnose live tuberculosis in an hour and help monitor the efficacy of treatments. That’s particularly critical because many TB strains have evolved defenses against standard treatments. Jianghong Rao, PhD, a professor of radiology at Stanford who led the work, says that speedy TB

(HealthDay)—For patients with newly diagnosed head and neck cancer (HNC), quality of life may improve with marijuana use, according to a study published online Aug. 2 in JAMA Otolaryngology-Head & Neck Surgery. Han Zhang, M.D., from McMaster University in Hamilton, Canada, and colleagues conducted a prospective cohort study involving patients enrolled at the time of

Scientists from the University of Jyväskylä, Finland, and from University of Cambridge, United Kingdom, have found new functions and structural details of muscle attachment structures. The research is important for the basic understanding of regulation of muscle function, for instance, in muscular dystrophy patients and for muscle adaptation in physical activity and sports. In multicellular

(HealthDay)—Teenagers’ use of any tobacco products, including electronic cigarettes (e-cigarettes), is associated with subsequent marijuana use, according to a study published in the August issue of Pediatrics. Janet Audrain-McGovern, Ph.D., from the University of Pennsylvania in Philadelphia, and colleagues examined whether adolescent e-cigarette, hookah, or combustible cigarette use is associated with initiating and currently using

As a kid, waiting to see if there would be any new Girl Scout cookie flavors was always one of the most exciting parts of the year. There were hits (I would sell my husband for one more box of Praline Royales) and flops (cinnamon-oatmeal raisin bars aren’t cookies for the love of God), but

More than two-thirds of women with ovarian cancer have high-grade serous carcinoma (HGSC). Up to 90 percent of HGSCs are not detected until they are beyond the ovaries or fallopian tubes, at which point it may not be possible to fully remove the tumor. Many of these cancers are now known to originate in the

An outbreak of cholera has killed 13 people in Niger’s southern Maradi region, which is home to the country’s economic capital, officials and the UN said on Saturday. Nearly 1,000 people, most of them children, have been affected by the outbreak which was first detected just over a month ago, the UN’s Office for the

In the world of online dating, men and women look to find someone a little out of their league, according to a new study. Scientists who analyzed user data from a popular dating site have found that heterosexual men and women reach out to potential dating partners who are on average about 25 percent more

The dentate gyrus of the hippocampus is part of the brain that helps form memories. It is also one of just two areas in the adult brain where new neurons are continuously formed. The dentate gyrus is part of a circuit that receives electrical signals from an area of the brain cortex that processes sensory

A new study from the University of North Carolina at Chapel Hill found that substandard and falsified medicines, including medicines to treat malaria, are a serious problem in much of the world. In low- and middle-income countries, more than 13 percent of the essential medicines that satisfy the priority health care needs of the population

The brain is a precision instrument. Its function depends on finely calibrated electrical activity triggering the release of chemical messages between neurons. But sometimes the brain’s careful balance is knocked out of control, as in epilepsy. Electroencephalography, or EEG, visualizes a brain’s electrical activity and can reveal how an epileptic seizure diverges from the predictable

A study led by researchers at Center for Infection and Immunity (CII) at Columbia University’s Mailman School of Public Health and the Department of Medicine at the Columbia University Irving Medical Center reports on the use of a genetic sequencing method to identify viral pathogens behind unexplained respiratory illnesses in Uganda over a five-year period.
