A comprehensive map of how Alzheimer's affects the brain: Analysis of genes altered by the disease could provide targets for new treatments

This analysis could offer many potential new drug targets for Alzheimer's, which afflicts more than 5 million people in the United States.

Human influence on global droughts goes back 100 years, NASA study finds

The study, published in the journal Nature, compared predicted and real-world soil moisture data to look for human influences on global drought patterns in the 20th century.

Radical desalination approach may disrupt the water industry

If hypersaline brines are improperly managed, they can pollute both surface and groundwater resources.

Magnets can help AI get closer to the efficiency of the human brain: New brain-like networks could help robots approach human-like efficiency at object recognition tasks

Purdue University researchers and experts in brain-inspired computing think part of the answer may be found in magnets..

Nature's dangerous decline 'unprecedented,' species extinction rates 'accelerating'

"The overwhelming evidence of the IPBES Global Assessment, from a wide range of different fields of knowledge, presents an ominous picture," said IPBES Chair, Sir Robert Watson.

Plastic gets a do-over: Breakthrough discovery recycles plastic from the inside out: Scientists have made a next-generation plastic that can be recycled again and again into new materials of any color, shape, or form

Now a team of researchers at the U.S.

Why you love coffee and beer

Scientist Marilyn Cornelis searched for variations in our taste genes that could explain our beverage preferences, because understanding those preferences could indicate ways to intervene in people's diets. To Cornelis' surprise, her new Northwestern Medicine study showed taste preferences for bitter or sweet beverages aren't based on variations in our

Stickier than expected: Hydrogen binds to graphene in 10 femtoseconds: Bound for only ten quadrillionths of a second

The international research team bombarded graphene with hydrogen atoms.

Despite health warnings, Americans still sit too much: Survey of 50,000 people across multiple ages, racial, ethnic groups documents troubling trends

The research team analyzed surveys of 51,000 people from 2001 to 2016 to track sitting trends in front of TVs and computers and the total amount of time spent sitting on a daily basis.

Deadly box jellyfish antidote discovered using CRISPR genome editing: Pain researchers uncover secrets to box jellyfish venom

The Australian box jellyfish (Chironex fleckeri) has about 60 tentacles that can grow up to three metres long.Each tentacle has millions of microscopic hooks filled with venom.

Arctic warming will accelerate climate change and impact global economy

A new paper in Nature Communications reveals a combination of these factors has the potential to increase the long-term economic impact of climate change by just under $70 trillion, under mitigation levels consistent with current national pledges to cut carbon emissions (5% of the estimated total cost of climate change

Running may have made dinosaurs' wings flap before they evolved to fly: New evidence suggests that passive wing flapping may have arisen earlier than gliding flight

The findings, published in PLOS Computational Biology, provide new insights into the origin of avian flight, which has been a point of debate since the 1861 discovery of Archaeopteryx.

Experimental device generates electricity from the coldness of the universe

An international team of scientists has demonstrated for the first time that it is possible to generate a measurable amount of electricity in a diode directly from the coldness of the universe..

Knit 1, purl 2: Assembly instructions for a robot? Researchers make soft, actuated objects using commercial knitting machines

Software developed by researchers from CMU's Morphing Matter Lab and Dev Lab in the Human-Computer Interaction Institute makes it possible for the objects to emerge from the knitting machines in their desired shapes and with tendons already embedded. They can then be stuffed and the tendons attached to motors, as

Water found in samples from asteroid Itokawa: Up to half of Earth's ocean water may have come from impacts by asteroids

The team's findings suggest that impacts early in Earth's history by similar asteroids could have delivered as much as half of our planet's ocean water.
