Device creates negative mass and and a novel way to generate lasers
Most objects react in predictable ways when force is applied to them—unless they have "negative mass." And then they react exactly opposite from what...
Dual migration created genetic ‘melting pot’ of the first Scandinavians
New genomic data suggest that the first human settlers on the Scandinavian peninsula followed two distinct migration routes. The study publishing January 9 in...
Mass extinctions remove species but not ecological variety
Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered...
Life on land and tropical overheating 250 million years ago
One of the key effects of the end-Permian mass extinction, 252 million years ago, was rapid heating of tropical waters and atmospheres.
How this affected...
Climate change drives collapse in marine food webs
A new study has found that levels of commercial fish stocks could be harmed as rising sea temperatures affect their source of food.

Black hole research could aid understanding of how small galaxies evolve
Scientists have solved a cosmic mystery by finding evidence that supermassive black holes prevent stars forming in some smaller galaxies.
These giant black holes are...
Slow-release weekly pill developed to deliver HIV therapeutics
Researchers at MIT and Brigham and Women's Hospital have developed a capsule that can deliver a week's worth of HIV drugs in a single...
Planets around other stars are like peas in a pod
An international research team led by Université de Montréal astrophysicist Lauren Weiss has discovered that exoplanets orbiting the same star tend to have similar...
Engineers grow functioning human muscle from skin cells
Biomedical engineers have grown the first functioning human skeletal muscle from induced pluripotent stem cells.
The advance builds on work published in 2015 when researchers...
Noise pollution causes chronic stress in birds, with health consequences for young
Birds exposed to the persistent noise of natural gas compressors show symptoms remarkably similar to those in humans suffering from post-traumatic stress disorder, new...
Alzheimer’s drug turns back clock in powerhouse of cell
The experimental drug J147 is something of a modern elixir of life; it's been shown to treat Alzheimer's disease and reverse aging in mice...
