How Early Should Young Women Should Start Thinking About Their Fertility?
Dr. Kutluk Oktay, Dr. Marjorie Dixon and Sybil Azur explain how early young women should start thinking about their fertility.
Positive parenting can reduce the risk that children develop obesity
New research from Penn State found that children with positive, early interactions with their care givers — characterized by warmth, responsiveness, and a sitmulating home environment — were at reduced risk of childhood obesity. “A lot of the discussion around childhood obesity and other health risks focuses on identifying and studying the exposure to risk,” […]
Scientists unveil promising new approach to diabetes prevention: Experimental compound protects obese mice from diabetes-like metabolic changes
A team of scientists from Scripps Research has conducted promising early tests of a new strategy that might one day be used to prevent or treat type 2 diabetes. The scientists, whose results are reported in Nature Communications, tested an experimental compound called IXA4 in obese mice. They showed that the compound activates a natural […]
What can 35-year-old stool samples tell scientists about HIV/AIDS?
Men who contracted HIV in the early days of the HIV/AIDS pandemic harbored a greater relative abundance of pro-inflammatory vs. anti-inflammatory gut microbes before they became HIV-positive compared to their counterparts who remained HIV-negative, according to new research published today in the journal Microbiome. In addition, the men who progressed to AIDS the quickest had […]
ALMA scientists detect signs of water in a galaxy far, far away: New study marks most distant detection of required element for life as we know it in a regular star-forming galaxy
Water has been detected in the most massive galaxy in the early Universe, according to new observations from the Atacama Large Millimeter/submillimeter Array (ALMA). Scientists studying SPT0311-58 found H20, along with carbon monoxide in the galaxy, which is located nearly 12.88 billion light years from Earth. Detection of these two molecules in abundance suggests that […]
Zeroing in on the origins of Earth’s ‘single most important evolutionary innovation’: A new study shows oxygenic photosynthesis likely evolved between 3.4 and 2.9 billion years ago.
Some time in Earth’s early history, the planet took a turn toward habitability when a group of enterprising microbes known as cyanobacteria evolved oxygenic photosynthesis — the ability to turn light and water into energy, releasing oxygen in the process. This evolutionary moment made it possible for oxygen to eventually accumulate in the atmosphere and […]
Ancient DNA rewrites early Japanese history — modern day populations have tripartite genetic origin
Ancient DNA extracted from human bones has rewritten early Japanese history by underlining that modern day populations in Japan have a tripartite genetic origin — a finding that refines previously accepted views of a dual genomic ancestry. Twelve newly sequenced ancient Japanese genomes show that modern day populations do indeed show the genetic signatures of […]
How Long Exactly Is Long COVID?
Almost half of patients hospitalized with COVID-19 early in the pandemic had at least one lingering symptom a year after symptom onset, researchers in Wuhan, China found. A total of 49% of patients had at least one post-COVID symptom 1 year later, which included sleep difficulties, palpitations, joint pain, or chest pain, though that was […]
Start Rhythm Control Early for Afib With Heart Failure
Tackling rhythm control early, with ablation or antiarrhythmic medication in the first year after atrial fibrillation (Afib) diagnosis, helped outcomes in people with heart failure (HF), a prespecified subanalysis of the EAST-AFNET 4 trial showed. The early strategy cut the composite of cardiovascular death, stroke, or hospitalization for worsening HF or for acute coronary syndrome […]
Phone Calls Spot Early Alzheimer’s
Speech patterns in phone conversations can spot people with early to moderate Alzheimer’s dementia, a Japanese study suggested. A machine-learning predictive model correctly identified people with Alzheimer’s dementia with about 90% accuracy using audio files of phone conversations of 24 people with confirmed Alzheimer’s and 99 healthy controls, reported Akihiro Shimoda, MPH, of McCann Health […]
