Mars Gullies Likely Not Formed by Liquid Water

New findings using data from NASA’s Mars Reconnaissance Orbiter show that gullies on modern Mars are likely not being formed by flowing liquid water. This new evidence will allow researchers to further narrow theories about how Martian gullies form, and reveal...

Five Years Post-Launch, Juno Is at a Turning Point

Five years after departing Earth, and a month after slipping into orbit around Jupiter, NASA’s Juno spacecraft is nearing a turning point. On July 31 at 12:41 p.m. PDT (3:41 p.m. EDT), Juno will reach the farthest point in its orbit of Jupiter for the first...

Frequent nut consumption associated with less inflammation

In a study of more than 5,000 people, investigators from Brigham and Women’s Hospital have found that greater intake of nuts was associated with lower levels of biomarkers of inflammation, a finding that may help explain the health benefits of nuts. The results...

Cognitive ability varies, but prejudice is universal

When it comes to prejudice, it does not matter if you are smart or not, or conservative or liberal, each group has their own specific biases. In a recent study, psychologists show that low cognitive ability (i.e., intelligence, verbal ability) was not a consistent...

Breastfed preemies turn out smarter

A new study, which followed 180 pre-term infants from birth to age seven, found that babies who were fed more breast milk within the first 28 days of life had had larger volumes of certain regions of the brain at term equivalent and had better IQs, academic...

Portable device produces biopharmaceuticals on demand

For medics on the battlefield and doctors in remote or developing parts of the world, getting rapid access to the drugs needed to treat patients can be challenging. Biopharmaceutical drugs, which are used in a wide range of therapies including vaccines and treatments...

Marrow cells’ role in pulmonary hypertension explored

Cells from the bone marrow participate in the development of pulmonary arterial hypertension (PAH), and they can also protect against it, according to new findings from a team of Vanderbilt University Medical Center investigators. It was known that bone marrow-derived...

Chorus of black holes radiates X-rays

Supermassive black holes do not give off any of their own light, hence the word “black” in their name. However, many black holes pull in, or accrete, surrounding material, and emit powerful bursts of X-rays. Collectively, these active black holes...

The Problem with Food Subsidy in the U.S. Farm Bill

There’s something new to worry about in your food. It’s linked to obesity, higher levels of unhealthy fat and inflammation, and although few other countries have to deal with it, it’s almost impossible to remove from our diet because it’s baked into the way we eat in...

New material could advance superconductivity

Scientists have looked for different ways to force hydrogen into a metallic state for decades. A metallic state of hydrogen is a holy grail for materials science because it could be used for superconductors, materials that have no resistance to the flow of electrons,...
