To ancient astronomers, Theta Eridani was brighter for 1,000 years—now we know why
To ancient astronomers, Theta Eridani was brighter for 1,000 years—now we know why
There's a bit of a historical mystery surrounding the star Theta Eridani. Ptolemy in the second century A.D. and al-Sufi in A.D. 964 both recorded Theta Eridani as one of the 13 brightest stars in the sky. Hipparchus may have said the same. But there's a problem. For it to be one

Dark energy flips its sign, but the Hubble tension refuses to budge
For nearly a century, astronomers have known that the universe is expanding. In the late 1990s, two independent teams, the Supernova Cosmology Project, led by Saul Perlmutter, and the High-Z Supernova Search Team, led by Brian Schmidt and Adam Riess, discovered something strange:

Grasses provide most of the world's calories—but we're only now starting to learn how they
If we want to dismiss something as irrelevant, we'd say that it's "as boring as watching the grass grow." And yet grasses—including corn, wheat and rice—make up most of the plant-based calories humans eat, as well as most of the calories fed to livestock. Perhaps we should have b

X-ray tracking reveals uneven expansion in young supernova remnant G292.0+1.8
X-ray tracking reveals uneven expansion in young supernova remnant G292.0+1.8
By analyzing data from NASA's Chandra X-ray Observatory, Dutch astronomers have investigated a young, oxygen-rich supernova remnant known as G292.0+1.8. Results of the new study, published June 29 on the arXiv preprint server, yield important insights into the expansion of this r

Secure glass containers for storing chemical waste through laser welding
As the adoption of electric vehicles continues to grow, so does the need for the safe and permanent storage of battery materials and industrial chemical waste. Certain waste streams require disposal in what are known as Category IV landfills, which impose particularly stringent r

In my years of spearfishing, I’ve never encountered more sharks than now. But I know where
Below the surface is one of the only places I can switch my brain off. Coming face to face with a shark comes with the territory – and we all have to adapt to this new normalThe first time I came face to face with a great white shark I felt something shift inside me. One look int

Columbia scientists discover surprising link between serotonin and heart valve disease
Columbia scientists discover surprising link between serotonin and heart valve disease
Scientists have uncovered evidence that serotonin, the chemical best known for regulating mood, may also speed the progression of a common heart valve disease in some people. The research suggests that patients with degenerative mitral regurgitation who take SSRI antidepressants

Self‑building molecular rings bring next‑generation drug delivery and smart materials clos
Rotaxanes are dumbbell-shaped mechanically interlocked molecules in which one or more ring-shaped molecules are threaded through a linear segment, known as the axle. To keep the ring from sliding off, two bulky groups, sometimes called stoppers, are added to the ends of the axle.

Spider-like creatures help uncover the surprising origins of fatherhood
Citizen scientists have helped researchers solve a long-standing mystery about how parental care evolved in harvestmen. Using photos and observations from iNaturalist, scientists more than doubled the known cases of egg-guarding behavior and discovered that maternal and paternal

Quantum-gravitational mechanism could explain the universe's homogeneity
Quantum-gravitational mechanism could explain the universe's homogeneity
Our universe is known to be remarkably homogeneous and isotropic. This essentially means that matter is distributed evenly throughout the universe and that it looks almost the same in all directions.

Scientists strike invisible gold in the deep sea—locked inside fool's gold
Pyrite, an iron sulfide ore, is often known as fool's gold because its shiny metallic luster and pale brass-yellow color can easily fool the untrained eye into mistaking it for real gold. This time, however, 360 kilometers (220 miles) south of Tokyo, scientists have uncovered inv

A 200-year-old physics experiment could help build future computers
Scientists at Nanyang Technological University in Singapore have discovered a surprisingly simple way to create exotic light structures called optical skyrmions using a 200-year-old optical effect known as the Poisson spot. Instead of relying on expensive, highly engineered mater
