After years of research, scientists have worked out how some bacteria are able to survive inside amoebae – by stabbing them with microscopic daggers to prevent digestion. This miniature game of biological swordplay was discovered through a new method where amoebae are frozen to minus 180°C (minus 292°F) and then gradually chiselled with a focussed

Scientists have developed a packaging-free, instantly dissolvable milk capsule that you can drop straight into your hot beverage, making them easier to use than the conventional little cartons we’re all used to, and reducing waste along the way. They’re essentially like sugar cubes but for milk, and the team behind them says they’re produced along

One manufacturing company just made history by successfully using a special 3D printer in extreme, space-like conditions. The team printed polymer alloy parts in a super-high vacuum, and hope their new tech will allow the design and manufacture of much more ambitious spacecraft and space-based telescopes. “This is an important milestone, because it means that

For the first time, researchers have amazingly captured the offshore calls of Gentoo penguins as they forage in the freezing waters of the Antarctic Ocean. Using miniature GoPro-style ‘penguincams’ fastened to the backs of the seabirds, the team found that vocal communication amongst these penguins is linked to group formation rather than food gathering. The

A baby dolphin died last week after hundreds of beachgoers in southern Spain surrounded the animal to touch and take pictures with it, sparking condemnation from a local animal rescue group. The incident took place last Friday in Mojácar, on the country’s southeastern coast, according to Equinac, a Spanish nonprofit organisation that advocates for marine

The historic 1987 treaty to fight the hole in the ozone layer wasn’t just an international success story – it was a stunning environmental victory that’s still saving the planet in unexpected ways some 30 years later. The Montreal Protocol successfully outlawed harmful chemicals that deplete ozone in the atmosphere, but new research shows the

The word ‘nice’ has an unusual history in the English language. Originally a term for ‘foolish’, its meaning over the centuries has morphed from ‘wanton’ to ‘reserved’ to ‘fastidious’. These days, it has become a somewhat bland and opaque description of personality: “she’s really nice.” But its common usage hints at the characteristics that matter

Scientists have used complex computer simulations to figure out what lies beneath Neptune’s icy surface, finding a rare compound that gives us a greater understanding of how gas giants are evolving. The simulations suggest a little-known compound called ammonia hemihydrate is lurking inside Neptune, a compound created when frozen water and ammonia mix together. The
