A see-through zebrafish and enhanced imaging provide the first direct glimpse of how blood stem cells take root in the body to generate blood.
Scientists are unraveling a mystery behind a fairly common disease that leads to heart failure: Why do some people with a key mutated gene fall ill while others stay healthy? Researchers tested more than 5,200 people to tease apart when mutations really are harmful or are just bystanders.
Researchers have found a possible predictor for little understood -- but often disabling or even fatal -- stroke complications.
Scientists have found that a transcription factor protein may be critical for normal respiratory function.
The fructose-glucose mixture found in high-fructose corn syrup was more toxic to mice than sucrose or table sugar.
Studies consistently show that people born weighing 6 pounds or less face an increased risk for type 2 diabetes as adults.
Researchers have developed an entirely new type of pill that tricks the body into thinking it has consumed calories, causing it to burn fat.
Investigators working to unravel the impact of genetics versus environment on traits such as obesity may also need to consider a new factor: when individuals were born.
The Cleveland Clinic recently unveiled their annual Top 10 Medical Innovations for 2015– a list that casts an optimistic light on up-and-coming healthcare advances that may reach consumers next year.
Like human patients, mice with a form of Duchenne muscular dystrophy undergo progressive muscle degeneration and accumulate connective tissue as they age. Now, researchers at the Stanford University School of Medicine have found that the fault may lie at least partly in the stem cells that surround the muscle fibers.
Researchers at NYU Langone Medical Center have developed the first large animal model of an inherited arrhythmic syndrome – an advance that will lead to a better understanding of the biologic mechanisms important in normal heart conduction and rhythm.
A hard hit to the chest can cause an irregular heartbeat that may lead to death even days after the impact.
In a new study, researchers demonstrated an association between smoking and loss of the Y chromosome in blood cells. The researchers have previously shown that loss of the Y chromosome is linked to cancer.
The Mediterranean diet consistently has been linked with an array of health benefits, including decreased risk of chronic disease and cancer. Until now, however, no studies had associated the diet with longer telomeres, one of the biomarkers of aging. Read more...
These days, with the abundance of artificial light, TV, tablets and smartphones, adults and children alike are burning the midnight oil. What they are not burning is calories: with later bedtimes comes the tendency to eat. Read more...
Anyone who has experienced Los Angeles gridlock likely can attest that traffic may cause one's blood pressure to rise. But researchers have found that, beyond the aggravation caused by fellow drivers, traffic-related air pollution presents serious heart health risks.
Researchers had never shown exactly how cells in the brain stem detect carbon dioxide and regulate breathing in humans. After taking a mutation from a two-month-old baby and expressing it in human astrocytes, they did exactly that, and the research may lead to an early warning system to save premature infants.
Harvard Stem Cell Institute scientists at Brigham and Women’s Hospital say they have found the cellular origin of the tissue scarring caused by organ damage associated with diabetes, lung disease, high blood pressure, kidney disease, and other conditions. Read more...
Using an ultrasensitive blood test to detect the presence of a protein that heralds heart muscle injury, researchers from Johns Hopkins and elsewhere have found that obese people without overt heart disease experience silent cardiac damage that fuels their risk for heart failure down the road. Read more...
An experimental 3-dimensional printed model of the heart may help surgeons treat patients born with complicated heart disorders, according to new research.
Research shows that taking a cholesterol-lowering drug for five years in middle age can lower heart and death risks for decades afterward. The benefits seem to grow over time and may last for life.
People with mental health problems are “significantly” more likely to have stroke or heart disease, according to a study unveiled at a recent Canadian Cardiovascular Congress.
UCLA scientists have discovered that statins, a popular class of cholesterol drugs, reverse the learning disabilities caused by a genetic disorder called Noonan syndrome. Read more..
The new Healthy Heart Score developed by researchers at the Harvard T.H. Chan School of Public Health (HSPH) gives individuals an easy way to estimate their 20-year risk of developing cardiovascular disease (CVD) based on simple lifestyle habits. Read more...
A team of researchers have used a laser beam trap to examine how drug particles from asthma inhalers behave as they are projected through the air. Their findings could improve the effectiveness of inhalers for the over five million people in the UK suffering from asthma.
