Predictive program projected to save lives and reduce unnecessary surgeries Combining a wealth of information derived from previous studies with data from more than 500 patients, an international team led by researchers from Johns Hopkins has developed a computer-based set of rules that more accurately predicts when patients with a rare heart condition might benefit—or
Mouse Study Suggests Gut Sensors Monitor the Hydration Potential of Each Drink You Take Water bottles are everywhere these days, along with all kinds of advice about exactly how much water you should be drinking. But how does your brain actually know when you’ve had enough and can stop feeling thirsty? A new UC San
With modern, guideline-directed therapy,1 which includes angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), β-receptor blockers, mineralocorticoid receptor blockers, and angiotensin receptor neprilysin inhibitors, up to 40% of patients with dilated cardiomyopathy (heart failure with reduced ejection fraction) may experience a return of left ventricular ejection fraction (LVEF) and ventricular geometry to normal.2 This encouraging result
An important achievement in stem cell research was recognized in 2012, when the Nobel Prize in Physiology or Medicine was awarded to two scientists who transformed the field: Shinya Yamanaka and John Gurdon. Together, they received the award for “the discovery that mature cells can be reprogrammed to become pluripotent.” The impact of this breakthrough
As artificial intelligence continues to evolve, diagnosing disease faster and potentially with greater accuracy than physicians, some have suggested that technology may soon replace tasks that physicians currently perform. But a new study from the Google AI research group shows that physicians and algorithms working together are more effective than either alone. It’s one of
https://www.nature.com/articles/s41591-019-0375-9 Reports of old brains’ decrepitude have been greatly exaggerated, scientists reported on Monday, unveiling results that contradict a much-discussed 2018 study and instead support the idea that human gray matter is capable of generating new neurons up to the ninth decade of life. The research, published in Nature Medicine, also found that old brains from
Statistical significance has become an infallible doctrine of scientific research. However, many scientists and statisticians argue that long-held beliefs about statistical significance have, in fact, harmed the scientific community. In hypothesis testing, the p-value gives the probability or likelihood that the null hypothesis is true and is frequently used as a measure of “statistical significance.”
A mouse study finds that when blood platelets are activated during exercise, they release factors that increase the number of newborn neurons in the hippocampus. It’s well established that exercise is good for the mammalian brain. As early as 1999, researchers discovered considerably more newborn neurons in the hippocampi of mice that had access to
Fibrodysplasia ossificans progressiva (FOP) is a rare, genetic disease in which damaged muscle and soft tissue turn into bone It affects just 800 people worldwide and there is currently no known cure Three drugs have entered clinical trials as potential treatments for the condition They target the genes and proteins responsible for the hyperactive bone growth
Question Is consuming dietary cholesterol or eggs associated with incident cardiovascular disease (CVD) and all-cause mortality? Findings Among 29 615 adults pooled from 6 prospective cohort studies in the United States with a median follow-up of 17.5 years, each additional 300 mg of dietary cholesterol consumed per day was significantly associated with higher risk of incident CVD (adjusted
