Starting schools before 8:30 a.m. shows a tragic disregard for both the mental health of children and for science.

New research from USC has uncovered a previously unknown genetic risk factor for Alzheimer’s disease and related dementias. The study provides insights on how these conditions, and other diseases of aging, might one day be treated and prevented. The research from the Cohen Lab at the USC Leonard Davis School of Gerontology sheds new light on the protective role of a naturally occurring mitochondrial peptide, known as humanin.

Ten years ago, it was too-easy credit that brought financial markets to their knees. Today, it could be a global debt of $247 trillion that causes the next crash. After a decade of escalating US household debt brought on by low wages and the national debt more than doubling over the same time frame, to $21 trillion, debt could soon put the brakes on this economic recovery, analysts warn.

Ahmet Hergune was killed during the conflict between Greek Cypriots and Turkish Cypriots in 1974

Although depression is one of the leading psychiatric disorders in Germany, its cause remains unclear. A recent study at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig, Germany, and the Department of Psychiatry and Psychotherapy of the University Clinic in Leipzig found that those affected by depressive disorder have a larger hypothalamus compared to their healthy counterparts.

A new type of battery developed by researchers at MIT could be made partly from carbon dioxide captured from power plants. Rather than attempting to convert carbon dioxide to specialized chemicals using metal catalysts, which is currently highly challenging, this battery could continuously convert carbon dioxide into a solid mineral carbonate as it discharges.

Japan's space agency (JAXA) has made history by successfully landing two robotic explorers on the surface of an asteroid. The two small "rovers", which were despatched from the Hayabusa-2 spacecraft on Friday, will move around the 1km-wide space rock known as Ryugu. The asteroid's low gravity means they can hop across it, capturing temperatures and images of the surface.

The seafloor is one of the last unexplored regions of our watery planet. On a recent expedition dubbed Deep Search 2018, a group of ocean researchers discovered 85 miles of deep-sea coral reef off the coast of the southeastern US. "Good news is too rare these days, and this is a victory that we can all share. We have found a pristine coral reef in our own backyard," Erik Cordes, the chief scientist on the expedition and a deep-sea ecologist at Temple University, wrote in a mission summary.

'There haven’t been any new drugs last 15 years, so it’s very promising to have uncovered a reason why some of that research may have failed'

Scientists say they have taken a potentially important — and possibly controversial — step toward creating human eggs in a lab dish. A team of Japanese scientists turned human blood cells into stem cells, which they then transformed into very immature human eggs. The eggs are far too immature to be fertilized or make a baby. And much more research would be needed to create eggs that could be useful — and safe — for human reproduction.

A Silicon Valley startup called New Age Meats offered us a taste of the world's first pork sausage made in a lab without killing any animals. Here's how the cultured meat cooked, smelled, and tasted.

It’s the first step toward being able to mass produce human eggs using other people’s body tissues or blood.

On the British Columbia coast, the Heiltsuk First Nation asserts its rights to manage its resources, and who has access to them, through the seasonal herring harvest. By Ian Gill.

Sufficient sleep has been proven to help keep the body healthy and the mind sharp. But it’s not just an issue of logging at least seven hours of Z’s. A new study on sleep patterns suggests that a regular bedtime and wake time are just as important for heart and metabolic health among older adults. In a study of 1,978 older adults published online Sept. 21 by the journal Scientific Reports, researchers at Duke Health and the Duke Clinical Research Institute found people with...

Talk to your grandparents about marijuana - before somebody else does. The latest release of a massive federal drug use survey shows monthly marijuana use has skyrocketed among older Americans. The past decade, in fact, has seen a sea change in the demographics of marijuana use: As recently as the early 2000s, teens were more than four times more likely to use marijuana than 50 and 60 somethings.

Southern California went 87 days without a clean air day, the longest stretch of consecutive ozone pollution violations in at least 20 years. Regulators blame the persistence in pollution on hot, stagnant weather and are studying whether climate change is driving it.

Decades spent studying peer review, publication bias, and more have challenged the status quo, but journalologists say they have a long way to go

An enormous future particle detector is now within closer reach. The first data from a prototype experiment hint that scientists may have what it takes to build the planned neutrino detector. Known as the Deep Underground Neutrino Experiment, or DUNE, the experiment will use 70,000 metric tons of liquefied argon to study the secrets of these neutrinos — bizarre, nearly massless particles that may help reveal why matter is common in the universe but antimatter is rare. DUNE will eventually detect the tracks of charged particles, including electrons and their heavier cousins, muons, that are produced when neutrinos interact.

A pear seedling selection named Bradford was cloned by the gazillion to become the ubiquitous street tree of America’s postwar suburban expansion. Then it turned invasive. By Adrian Higgins.
