A history of gallstone disease may increase the risk of coronary heart disease, according to a new study by Tulane University researchers published in the American Heart Association’s journal Arteriosclerosis, Thrombosis and Vascular Biology. Researchers analyzed the...

A new Goldilocks for habitable planets

The search for habitable, alien worlds needs to make room for a second “Goldilocks,” according to a Yale University researcher. For decades, it has been thought that the key factor in determining whether a planet can support life was its distance from its sun. In our...

Vaping may lead to fewer respiratory infections for ex-smokers

The majority of smokers who successfully switch to vaping say they have fewer respiratory infections, according to a study led by Queen Mary University of London (QMUL). The on-line survey of 941 respondents assessed subjective changes in respiratory symptoms in...

Maternal language shapes infants’ cry melodies

Tonal languages sound rather strange to European ears: in contrast to German, French or English, their meaning is also determined by the pitch at which syllables or words are pronounced. A seemingly identical sound can mean completely different things –...

Recording analog memories in human cells

MIT biological engineers have devised a way to record complex histories in the DNA of human cells, allowing them to retrieve “memories” of past events, such as inflammation, by sequencing the DNA. This analog memory storage system — the first that can record the...

America’s wars take uneven toll

In today’s wars, Americans who die or are wounded in battle are disproportionately coming from poorer parts of the country, according to a new study released this week. By analyzing over 500,000 American combat casualties from World War II through Iraq and...

Insights into the dawn of the universe

What did the universe look like just after the Big Bang? How did the first stars and galaxies evolve? Seeking answers to these questions, researchers at Bielefeld University are looking way back into the past. With the digital radio telescope LOFAR, they are picking...

Venus-like exoplanet might have oxygen atmosphere, but not life

The distant planet GJ 1132b intrigued astronomers when it was discovered last year. Located just 39 light-years from Earth, it might have an atmosphere despite being baked to a temperature of around 450 degrees Fahrenheit. But would that atmosphere be thick and soupy...

Female forensic scientists more stressed than males

Women may be at the forefront of the fast-growing forensic science field, but they’re also more stressed than their male counterparts, indicates new research led by a Michigan State University criminologist. Females working in forensic science labs were almost two...

Yale study identifies how Zika virus infects the placenta

In a new study, Yale researchers demonstrate Zika virus infection of cells derived from human placentas. The research provides insight into how Zika virus may be transmitted from expectant mother to fetus, resulting in infection of the fetal brain. The study was...

Researchers Develop Safer Opioid Painkiller From Scratch

An international team of researchers — led by scientists at UC San Francisco, Stanford University, the University of North Carolina (UNC), and the Friedrich-Alexander University Erlangen-Nürnberg in Germany — has developed a new opioid drug candidate that blocks pain...

New mechanism discovered for Alzheimer’s risk gene

For decades, scientists have known that people with two copies of a gene called apolipoprotein E4 (ApoE4) are much more likely to have Alzheimer’s disease at age 65 than the rest of the population. Now, researchers at the Salk Institute have identified a new...
