How do humans perceive color? An NIH experiment finds a way to measure what happens after light hits the eye—using brain scans.
A clever technique allows scientists to scan a heart and reconstruct it in a soup of gelatin. It's like making jello, only way more useful for surgeons.
Two vaccines are nearly here—but their unusual storage requirements could deprive the rural areas that need them most. A tech fix might be coming.
The newly measured rate of a key nuclear fusion process that forged the first atomic nuclei matches the picture of the universe 380,000 years later.
As glaciers retreat and permafrost thaws, massive landslides threaten coastal communities. Those, in turn, could trigger giant sea waves.

The idea for solar thermal propulsion has been around for decades, but researchers tapped by NASA just conducted a first test.
Until Monday, the governor urged Iowans to “do the right thing” but kept businesses open and masks optional. Now cases are surging and hospitals are filling up.
Pfizer's new vaccine has to be stored at extremely low temperatures. Here's how things work when it gets that cold.
If they collide, it could cause big problems for breeding penguins and seals by cutting off their access to the open sea.
In a small study, the drug kept patients with mild symptoms from worsening. If it holds up in a larger test, it could help keep more people out of hospitals.
As usual, a lack of good data makes evaluating the risk of getting the virus on a flight hard to calculate. It’s probably low. It’s definitely not zero.
The epidemiologist calls it "the best of times and the worst of times," as good news on vaccines and testing coincides with a terrifying rise in cases.
With a surge in cases, there is no safe way to travel or gather for Thanksgiving or Christmas. But if you must, here are some ways to lower your risk.
Conflict forced scientists to abandon a gene bank, but not before duplicating their last remnants of essential crops in the Svalbard vault on a remote Arctic island.
Just how much material did OSIRIS-REx collect from Bennu? The method relies on something called the moment of inertia, and you can replicate it with a fan and a penny.
Genetic material from prehistoric dogs shows how early humans may have migrated with, bred, and cared for their canine companions.
For years, a master tool called indistinguishability obfuscation seemed too good to be true. Three researchers have figured out that it can work.
The popularity of outdoor recreation has skyrocketed during the pandemic. But now snow is on the way—and recovery missions are on the rise.
