Drinking water in developed countries is pretty clean, but hidden nasties can still lurk. One mysterious “phantom chemical” has haunted drinking water for decades, and now researchers have identified it – and found it’s completely new to science.

Researchers have developed a non-addictive painkiller that remains inactive until it reaches sites of chronic pain. Instead of dulling the nerves that send the pain signals like other analgesics, this new pain pill directly addresses the underlying cause.

Scientists have discovered the largest known protein in biology. Given the fun name of PKZILLA-1, the protein was found in algae cells and helps them make toxins that are responsible for mass killings of fish.

Scientists in Japan have developed a new method for breaking down toxic “forever chemicals” quickly and at room temperature. The technique broke down 100% of certain types of these pollutants overnight, recovering some useful components for reuse.

Tycho Brahe is best known as a Danish Renaissance astronomer. But he was also a bit of an alchemist, and a first-ever analysis on shards found at his former home from the 1500s has shed some light on just what he was up to in his basement lab.

Scientists have discovered the potential existence of a bizarre new molecule related to water. Dubbed “aquodiium,” this ion could form under extreme conditions and may explain some of the weirdness of our solar system’s ice giant planets.

The popular pain-killing drug paracetamol, also known as acetaminophen, has always been made from chemicals derived from environmentally damaging coal tar or crude oil. Now researchers have devised a greener way of producing the drug using wood.

Venus may be a hellscape, but there’s a chance some forms of life could evolve there. A new MIT study has now found that the building blocks of life are surprisingly stable in highly concentrated sulfuric acid – which Venus’ clouds are made of.

It’s a fundamental principle of physics that particles with opposite charges attract each other, while those with the same charge repel. Scientists have now discovered that under certain conditions, particles can attract those of the same charge.

We’ve all accidentally tied knots that we can’t untangle – but we don’t expect to win any world records. Now scientists have done exactly that, accidentally tying the world’s smallest and tightest knot in a tiny structure made of just 54 atoms.

Saturn’s moon Enceladus continues to climb the list of best places to look for life beyond Earth. New NASA data has detected a molecule thought to be key to the origin of life, and suggests there’s more chemical energy for life to chow down on.

A team of scientists from China's Northeast Normal University has developed an electrochemical method for extracting uranium from ordinary seawater that has the potential to supply humanity with an effectively unlimited energy source.
