Researchers discover why fructose doesn't satisfy hunger like glucose

A new study found that fructose and glucose may look the same on a nutrition label, but the brain treats them very differently. In mice, glucose strongly reduced activity in hunger-promoting brain cells, while fructose had a much weaker effect. High-fructose corn syrup triggered

Climate sceptics cheering as they melt in record temperatures? This heatwave is where sati

Delegates at an ‘anti-woke’ conference disparaged Ed Miliband’s net zero policies. But even they could not ignore the sweat on their foreheadsIt was hardly a perfect film, but I keep thinking of Don’t Look Up. In its depiction of a world that stubbornly refuses to heed the warnin

How NASA taught four astronauts to read the moon

How do you teach someone to look at the moon? Not glance at it, the way we all have on a clear night, but truly read it, the way a geologist reads a hillside. That was the challenge NASA set itself before Artemis II, because when Reid Wiseman, Victor Glover, Christina Koch and Je

Why Ho Chi Minh City's pollution sources may have been misread for years

Biomass burning, including the combustion of wood, charcoal and agricultural residues, is a major source of PM2.5, a fine particulate matter that degrades air quality and poses risks to human health. Much of this pollution is tracked by looking at levels of levoglucosan, a chemic

Lamprey brain atlas reveals 450-million-year blueprint of vertebrate brains

What did the very first complex vertebrate brain look like? To find out, scientists turned to an unlikely time traveler: the lamprey, a jawless, eel-like fish whose body plan has barely changed in roughly 360 million years.

Testing the orbital mechanics of giant mirrors

Giant mirrors in space have been a staple of science fiction for decades. But so far, there's been very little work looking at the actual physics behind the concept—possibly because we're still so far from making them ourselves. Still, they could potentially serve as a passive te

Why scientists fear we're missing evidence of extraterrestrial life

Scientists are raising concerns that we may be overlooking evidence of extraterrestrial life even when it is present. Hidden biosignatures, limitations in detection technology, and assumptions about what life should look like can all create dangerous false negatives. The research

Nearby 'Super Earth' may be a better candidate for life than previously thought

Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf. Just 25 light-years
