Why the intrinsic quantum effects of axion dark matter are completely undetectable

Dark matter is an elusive form of matter that almost never emits, absorbs or reflects light, while only weakly interacting with regular matter. These properties make it very difficult to detect using conventional experimental ...

AI makes a major breakthrough in a math problem that had stumped experts for decades

For nearly 80 years, mathematicians have struggled to solve a classic geometry puzzle first posed by Paul Erdős in 1946: the planar unit distance problem. The question posed by the legendary Hungarian mathematician was, on ...

Second ribosome binding site helps explain how tetracyclines work

For decades, doctors have widely used tetracyclines for conditions ranging from acne to tick-borne illnesses. Using high-resolution imaging technology, researchers in the laboratory of Christopher Bunick, MD, Ph.D., associate ...

Rediscovering science: New knowledge hidden in old data

What if the knowledge that could fuel the next scientific breakthrough has simply been forgotten in an old graph or table? Valuable scientific insights may already exist across decades of published experiments, yet remain ...

How countries can build effective DNA barcoding networks

Aligning with the International Day for Biological Diversity's theme of "Acting locally for global impact," researchers have released a comprehensive blueprint for building a robust, globally adaptable network of DNA barcoding ...

Hubble captures galaxy cluster MACS J1141.6-1905

Look closely at this image from NASA's Hubble Space Telescope and you'll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily ...

Custom device maps carbon capture reactions in real time

Removing carbon dioxide (CO2) directly from the air, a process called direct air capture (or DAC), is one of several approaches being developed to help reduce the concentration of this greenhouse gas in the atmosphere. Among ...

Brutal field trip provides new insights into Arctic winter

It was the hardest field trip they had ever been on, but the result was both surprising and exciting. After hiking 9 kilometers with a 400-meter elevation gain and carrying heavy backpacks through very rocky terrain, the ...

Saturn's icy rings likely formed from lost moon Chrysalis

You're a long-necked Titanosaur grazing the plains and chomping away on tree leaves about 100 million years ago in the Early Cretaceous in what would eventually become a future Starbucks location. You look up at the night ...

The material science behind a spacecraft's impact armor

Aerospace engineers have to consider numerous factors when designing a spacecraft, but one that comes up more and more often is the need to design against micrometeoroids and orbital debris (MMOD). While most designers understand ...
