Caltech scientists have developed a new way to produce optical frequency combs—important tools in devices that keep time and measure distances very precisely—at the chip scale, an advance that should make it easier to incorporate ...

Earth's magnetic field acts as a vital shield against radiation arriving from space, but it is not constant. A new international study has examined how a reduction of the magnetic field similar to the Laschamps excursion ...

When you reach into a bucket of ice, open your front door on a snowy day, or feel the tingle of menthol toothpaste, a protein in your nerve cells called TRPM8 springs into action, opening like a tiny gate to send a "cold" ...

New research from the University of St Andrews has revealed that human readiness for intergroup violence is not a single or unified mindset. Published in the Proceedings of the National Academy of Sciences, the new study, ...

For decades, it has been widely believed that electrons move most efficiently in materials that are clean and highly ordered. Much like water flowing more easily through a smooth pipe, conventional wisdom has held that electrical ...

As bees and hummingbirds flit from flower to flower, greedily sipping nectar in exchange for pollination, the animals often get another treat: alcohol. In the first broad analysis of the alcohol content of flower nectars, ...

A team of scientists led by the U.S. Department of Energy's (DOE) Argonne National Laboratory has identified a rare, switchable quantum property in a new type of nickel sulfide material. The discovery could have applications ...

More than half a century after the groundbreaking Apollo program's last crewed flight to the moon, three men and one woman are preparing for a lunar journey set to turn a new page in American space exploration.

A research team led by Purdue University's W. Andy Tao has discovered a new type of protein modification related to cellular mutation that impairs a crucial enzyme's ability to help drive energy processes. Their discovery, ...

This past winter, the Rocky Mountains experienced an historic snow drought, a worrying development for the tens of millions of people in the arid American West who depend on snowmelt for water. Now, a new study in the journal ...

The economic damage yet to come from carbon dioxide emitted decades ago far exceeds the harm it has wrought so far, according to a new Stanford University study. The research, published in Nature, puts a dollar value on the ...

Large-scale quantum computers are waiting in the wings. One of the main reasons we don't have them yet is because quantum hardware is so noisy. This isn't the type of noise you'd want to shush in a crowded theater. When it ...
