Vision researchers have disproved a long-standing theory of how the human vision system processes images, using computational models and human experiments. The findings could have implications for the understanding of human vision and diagnosis of vision anomalies.
Read morePeople who carry around unhealthy amounts of weight don't just have heart disease and diabetes to worry about. Obesity is implicated in two thirds of the leading causes of death from non-communicable diseases worldwide and the risk of certain diseases differs for men and women.
Read moreA multicenter randomized clinical trial evaluating a new artificial pancreas system — which automatically monitors and regulates blood glucose levels — has found that the new system was more effective than existing treatments at controlling blood glucose levels in people with type 1 diabetes.
Read moreResearchers have identified several chemical signatures, detectable in blood and urine, that can accurately measure dietary intake, potentially offering a new tool for physicians, dieticians and researchers to assess eating habits, measure the value of fad diets and develop health policies.
Read moreResearchers have identified 57 genetic variations of a gene strongly associated with declines in blood oxygen levels during sleep. Low oxygen levels during sleep are a clinical indicator of the severity of sleep apnea, a disorder that increases the risk of heart disease, dementia, and death.
Read moreA new Global Health Security Index released today, the first comprehensive assessment and benchmarking of health security and related capabilities across 195 countries, suggests that not a single country in the world is fully prepared to handle an epidemic or pandemic.
Read moreHepatic insulin resistance, caused by diets high in sugar and fat, can lead to type 2 diabetes. Researchers found that the Elovl6 gene plays a key role in hepatic insulin resistance. Deleting Elov6 in liver cells causes a rise in a specific ceramide lipid that protects mice from hepatic insulin resistance due to excessive dietary sugar. The findings could help efforts to find a targeted treatment for the condition.
Read moreLarge-scale study to identify human adenovirus genotypes in Singapore leads to discovery of four new adenovirus strains and increase in strains linked to severe diseases. Researchers suggest use of antiviral therapies and adenovirus vaccines, and routine monitoring of adenovirus strains.
Read moreA breakthrough has been made in understanding a rare genetic skin disease that causes progressively enlarging skin tumors over the scalp, face and body.
Read moreRare diseases represent a global problem. Until now, the lack of data made it difficult to estimate their prevalence. The Orphanet database, which contains the largest amount of epidemiological data on these diseases taken from the scientific literature, has made it possible to obtain a global estimate.
