Untangling mixed (neural) signals: New research shows how ‘polyglot’ neurons encode and decode sensorimotor ‘chatter’
During sensorimotor processing in the brain, neurons are constantly bombarded with information from other neurons. When we use our eyes to interact with our environment, thousands of neurons communicate with each other to make sense of all the information coming in and react to it: If someone throws you a ball, your eyes track the […]
Air pollution exposure during pregnancy may boost babies’ obesity risk
Women exposed to higher levels of air pollution during pregnancy have babies who grow unusually fast in the first months after birth, putting on excess fat that puts them at risk of obesity and related diseases later in life, new CU Boulder research shows. The study of Hispanic mother-child pairs, published this week in the […]
Advanced analysis of Apollo sample illuminates Moon’s evolution
Sophisticated analysis of a rock sample taken from the Moon during the Apollo 17 mission revealed new information about the complex cooling and evolutionary history of the Moon. The findings, from University of Hawai’i (UH) at Manoa researchers, were published today in Nature Communications. Apollo 17 astronauts collected the rock sample troctolite 76535 from the […]
Chemicals from hair and beauty products impact hormones, especially during pregnancy
Use of certain personal care products during pregnancy may impact maternal hormone levels, according to a new Rutgers study. Personal care and beauty products contain several ingredients that often include a wide range of endocrine-disrupting chemicals like phthalates, parabens, phenols, parabens and toxic metals. These chemicals interact with hormone systems, influencing synthesis, regulation, transport, metabolism […]
Several Factors Contribute to GI Bleeding Mortality Risk
Patients who developed upper gastrointestinal (GI) bleeding during a hospital stay experienced worse adverse outcomes than those admitted for upper GI bleeding alone, French researchers found in a prospective study. Currently hospitalized patients (dubbed “inpatients”) with upper GI bleeding showed a significantly higher mortality rate at 6 weeks than patients hospitalized for GI bleeding alone […]
New findings on the link between CRISPR gene-editing and mutated cancer cells
A protein that protects cells from DNA damage, p53, is activated during gene editing using the CRISPR technique. Consequently, cells with mutated p53 have a survival advantage, which can cause cancer. Researchers at Karolinska Institutet in Sweden have found new links between CRISPR, p53 and other cancer genes that could prevent the accumulation of mutated […]
Scientists discover how oxygen loss saps a lithium-ion battery’s voltage: Measuring the process in unprecedented detail gives them clues to how to minimize the problem and protect battery performance
When lithium ions flow in and out of a battery electrode during charging and discharging, a tiny bit of oxygen seeps out and the battery’s voltage — a measure of how much energy it delivers — fades an equally tiny bit. The losses mount over time, and can eventually sap the battery’s energy storage capacity […]
‘Concerning’ Opioid Prescribing in Patients With Cirrhosis
Nearly one in five patients with cirrhosis were prescribed opioids during outpatient visits, more often than not by a primary care physician (PCP), according to a national analysis of over 10 million ambulatory visits. From 2006 to 2016, 17% of all outpatient visits for patients with cirrhosis resulted in an opioid prescription, usually a refill, […]
Moderate amounts of caffeine not linked to maternal health risks: In a prospective study of 2,529 pregnant women, drinking caffeinated beverages was associated with a reduced risk of developing gestational diabetes
Good news for pregnant coffee lovers: Consuming a low amount of caffeine during pregnancy could help to reduce gestational diabetes risk, according to researchers in the Perelman School of Medicine at the University of Pennsylvania and the National Institutes of Health. The findings were published Monday in JAMA Network Open. “While we were not able […]
