The energy and climate benefits of cool roofs have been well established: By reflecting rather than absorbing the sun’s energy, light-colored roofs keep buildings, cities, and even the entire planet cooler. Now a new study by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has found that cool roofs can also save water by reducing how much is needed for urban irrigation.

Thirty years after NASA and NOAA launched a groundbreaking airborne campaign to study the Antarctic ozone hole, the two federal science agencies have once again joined forces over the world’s highest, driest and coldest continent to sniff out the secrets of the atmosphere.

On Oct. 14, NASA’s heavily instrumented DC-8 flew over Antarctica as part of the Atmospheric Tomography Mission or ATom, an unprecedented effort to sample the remote atmosphere to understand the distribution of man-made pollutants and short-lived greenhouse gases.

When it comes to behaviour, researchers have moved beyond the “nature versus nurture” debate. It’s understood that genes and environment both play a role. However, how they interact at a molecular level to shape behaviour is still unclear.

A new study led by scientists at the University of Toronto sheds valuable light on this relationship. The paper, published in  Proceedings of the National Academy of Sciences of the United States of America, reveals how epigenetics – changes in gene expression that do not change DNA – interact with genes to shape different feeding behaviours in fruit flies. This research unlocks the molecular mechanism that leads “rover” flies to forage for food more than “sitter” flies.

It’s perhaps one of the most common emotions to feel in a relationship, but one that’s virtually untouched when it comes to studying relationships in monogamous primate species. What scientists have recently discovered about jealousy in pair-bonded titi monkeys at the California National Primate Research Center (CNPRC) offers insight into human emotions and their consequences.

What appears to be a unique selfie opportunity was actually a critical photo for the cryogenic testing of NASA’s James Webb Space Telescope in Chamber A at NASA’s Johnson Space Center in Houston. The photo was used to verify the line of sight (or path light will travel) for the testing configuration.

WhatsApp use by ambulance doctors in Argentina was associated with faster treatment of heart attack and lower mortality in an observational study presented today at the Argentine Congress of Cardiology (SAC 2017). The free messaging application was used to send diagnostic electrocardiograms (ECGs) directly to hospital catheterisation (cath) laboratories, enabling patients to bypass the emergency department.

The environmental impact of hydropower generation in the Amazon may be greater than predicted, according to new University of Stirling research.

Where people will go in the cosmos, plants will go. That’s the message of a paper entitled “Gardening for Therapeutic People-Plant Interactions during Long-Duration Space Missions” written by Raymond Odeh, and Charles L. Guy of the University of Florida (Gainesville) and published in the De Gruyter journal, Open Agriculture.

Snakes and spiders evoke fear and disgust in many people. Even in developed countries lots of people are frightened of these animals although hardly anybody comes into contact with them. Until now, there has been debate about whether this aversion is innate or learnt. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig and the Uppsala University have recently discovered that it is hereditary: Babies as young as six months old feel stressed when seeing these creatures—long before they could have learnt this reaction.

Rechargeable batteries based on magnesium, rather than lithium, have the potential to extend electric vehicle range by packing more energy into smaller batteries. But unforeseen chemical roadblocks have slowed scientific progress.
