Every year, billions of dollars' worth of crops worldwide perish due to pre-harvest sprouting (PHS), a phenomenon in which grain or seeds germinate on the plant before harvest. The process is triggered by a variety of factors, ...

For the first time, a quantum computer has successfully measured pairing correlations (quantum signals that show electrons teaming up in pairs), which is essential to helping scientists find one of the holy grails of physics—superconductors ...

For obvious reasons, we do not know what the inside of a black hole looks like. But thanks to theoretical physics, we can ask what the inside should look like if Einstein's theory of gravity and the rules of quantum mechanics ...

Researchers may have discovered the world's biggest spider web, a massive subterranean structure spanning over 100 square meters in a sulfur cave on the Albania–Greece border. The multilayered web along a wall near the cave ...

Paleontologists have long wrestled with the challenge of identifying the genders of dinosaurs from the fossils they leave behind. Once the soft tissues like reproductive organs have decayed away, distinguishing a male from ...

After years of trying, the electronic nose is finally making major progress in sensing smells, almost as well as its human counterpart. That is the conclusion of a scientific review into the development of neuromorphic olfactory ...

For years, astronomers have been on the hunt for the first generation of stars, primordial relics of the early universe. And now they may have just found them. Ari Visbal from the University of Toledo, Ohio and colleagues ...

Scientists have taken an unprecedented look at marine fish species living in the world's oceans by studying traces of genetic material in seawater. One of the most surprising results was discovering species in places where ...

Kevlar has met its match. For decades, it has been the gold standard for impact protection, from bulletproof vests to armored vehicles, and is still widely used. But scientists have now developed a new composite material ...

Every year, around 600 million people are struck down by foodborne illnesses. The culprits are often common yet dangerous bacteria, such as E. coli and Salmonella, that thrive in undercooked or improperly handled food. These ...

An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening dramatically and rapidly as it did so. The reason for the sudden extreme activity is currently puzzling ...

Idiopathic hypersomnia (IH) is a rare, chronic neurological disorder that causes people to feel excessively sleepy during the day, even after getting a full night's rest. Other symptoms include severe difficulty waking up ...

Ochre is an iron-rich mineral pigment that was used by many ancient civilizations for color, decoration and practical tasks such as preserving animal hides and tanning clothing. Recent analysis of fragments of ochre at several ...

As anyone who uses the internet will know, the way we find information has fundamentally changed. For the last three decades, search engines have delivered ranked lists of links in response to our queries, and it was our ...

The microscopic flatworm (Stenostomum brevipharyngium) is one of nature's weirder creatures. Chop off its head, and it'll grow one back. Cut it in half, and it'll become two separate healthy worms. And now scientists have ...
