Though some see snowstorms and believe global warming has been exaggerated, a new study using predictions of Greenland ice loss and its impact on rising sea levels instead finds that other models may be greatly underestimating it.  

The new estimate simulates future distribution of lakes that form on the ice sheet surface from melted snow and ice, called supraglacial lakes. Previously, the impact of supraglacial lakes on Greenland ice loss had been assumed to be small, but the new research has shown that they will migrate farther inland over the next half century, potentially altering the ice sheet flow in dramatic ways.

A new study says that delaying the cutting of the umbilical cord in newborns by two minutes leads to a better development of the baby during the first days of life - by influencing the resistance to oxidative stress in newborns.

How much science is in pop music? Can pop culture enhance science communication?

A sociology duo recently explored the occurrence of science in the lyrics of Taiwanese pop music. Their results revealed that expressions from the field of astronomy and space research are notably prominent in the lyrics. Most texts address emotional states, while the latest scientific topics are only rarely mentioned.

“In many countries, and that includes Austria in particular, there is a distinct gap between the sciences and the population, which must be bridged. Popular culture and the entertainment media, amongst others, could play a valuable part as intermediaries,” says co-author Joachim Allgaier.

Some people eat when they are hungry and stop when they are not. Others eat until they are full. For that second group, science may soon have a way to help keep them slimmer.

Inulin-propionate ester (IPE) contains propionate, which stimulates the gut to release hormones that act on the brain to reduce hunger. Propionate is produced naturally when dietary fiber is fermented by microbes in the gut and in its first tests in humans, researchers found that the ingredient is effective at preventing weight gain in overweight volunteers.

You may not have been born a criminal, but experiences influence how genetic variants affect the brain and therefore behavior, according to a new paper. 

The study used a survey of 1,337 students aged 17 or 18 in Västmanland, a Swedish county, who anonymously completed questionnaires reporting on delinquency, family conflict, experiences of sexual abuse, and the quality of their relationship with their parents. They also provided a sample of saliva from which the researchers extracted DNA to examine it. The Monoamine oxidase A (MAOA) gene is a key enzyme in the catabolism of brain neurotransmitters, monoamines, especially serotonin. Catabolism is the breaking down of complex materials and the releasing of energy within an organism.

Imagine that Brian promises to drive you to the airport but never shows up, and you miss your flight. When you confront Brian, he tells you that he remembered his promise but decided to watch a movie instead. Would you be angry? You betcha!

All complex life, including plants, animals and fungi, consists if of eukaryotic cells, cells with a nucleus, transport mechanisms and often organelles like mitochondria that perform the functions an organism needs to stay alive and healthy. Humans have 220 different kinds of eukaryotic cells which control everything from thinking and locomotion to reproduction and immune defense.

Because of that commonality, the evolution of the eukaryotic cell is considered one of the most critical events in the history of life on Earth. Without it, earth populated entirely by prokaryotes, single-celled organisms such as bacteria and archaea, with no chance at all of filming "Guardians of the Galaxy" or celebrating Christmas.

A new analysis to be presented next week at the American Geophysical Union's Fall Meeting in San Francisco says that extreme climate and weather events such as record high temperatures, intense downpours and severe storm surges are more common in many parts of the world.

It's hard to be sure. High quality weather records only go back about 30 years and even suspect quality records only go back 100, so there is inference between modern record-keeping and the data trapped in tree rings and ice cores from ancient times.
