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.

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.
Scientists have discovered gene mutations that give people naturally lower cholesterol levels and cut their risk of heart disease in half. That discovery may have a big implication for a blockbuster heart drug.
For years, a multidisciplinary research team has tracked an elusive creature, a complex of proteins thought to be at fault in some cases of sudden cardiac death. Now, they have finally captured images of the complex.
Scientists have identified chemicals found in some everyday fruit that could protect vital organs from long-term damage following a heart attack or stroke, according to new research.
Asthma may be more harmful than was previously thought, according to researchers who found that genetic damage is present in circulating, or peripheral, blood.
Engineers have determined for the first time the impact of a ring-shaped vortex on transporting blood flow in normal and abnormal ventricles within the human heart. In order to make the study possible, researchers have developed a novel ultrasound technology that makes screening cheaper and much easier.
The first embryonic stem (ES) cell trial for severe heart failure is launching now in Paris. The long-awaited trial comes after much preclinical cell work on more than 350 rats, 50 immunodeficient mice and 32 non-human primates.
When tissues are deprived of blood, as happens during a stroke or heart attack, the lack of oxygen can cause serious damage. A new study shows that surprisingly, a DNA-repair enzyme called Aag actually makes this damage worse.
A new study points to a convenient, free way to manage acute asthmatic episodes— catching some rays outside. The research showed that asthmatics with vitamin D deficiency were 25 percent more likely to experience acute attacks.
The seemingly miraculous power of babies’ hearts to repair themselves after being injured has spurred a research team to investigate if this ability can be harnessed for new heart attack treatments.
Researchers have discovered that some scar-forming cells in the heart, known as fibroblasts, have the ability to become endothelial cells— the cells that form blood vessels. The finding could point the way toward a new strategy for treating people who have suffered a heart attack
Short-term modest weight gains in healthy, normal weight young adults was associated with more bad cholesterol levels in those who ate muffins cooked using saturated oil. However, individuals in the same study who ate muffins made with polyunsaturated oils had improved blood cholesterol profiles, according to a new study.
In acute asthma, various triggers, including viral illnesses and aeroallergens, can cause acute narrowing of the airways leading to a life-threatening respiratory crisis and sometimes death. Researchers have identified a novel factor that puts the brakes on airway smooth-muscle contraction relevant to asthma.
Lethal fibrosis in lungs of mice with idiopathic pulmonary fibrosis (IPF) can be reversed, say researchers. No drug on the market can do this. But the crew pulled it off, in mice, by temporarily restoring (a mimic of) one of the body’s own anti-fibrosis agents, sharply reduced in IPF: microRNA-29.
A new study shows that physical activity can improve memory performance in older people through increasing volume and blood flow in an area of the brain called hippocampus.
Researchers have known for decades that stress contributes to heart disease. But a new analysis shows mental stress may tax women’s hearts more than men’s.
New research shows that the lungs become more inflammatory with age and that ibuprofen can lower that inflammation. In fact, immune cells from old mouse lungs fought tuberculosis bacteria as effectively as cells from young mice after lung inflammation was reduced by ibuprofen.
