A laboratory experiment in Hungary has spotted an anomaly in radioactive decay that could be the signature of a previously unknown fifth fundamental force of nature, physicists say – if the finding holds up.
At a distant star called Kepler-223, four gas giant planets orbit close in to their sun. It couldn’t be more different from our own solar system today, where all the big planets hang out far away. But could Kepler-223 be how our solar system was long ago?
Finding more’invisible’ dwarf galaxies could help astronomers solve one of the biggest questions: what is the Universe made of?
Knowing whether these dwarf galaxies exist – and if so, how many there are – is crucial for solving one of the biggest cosmic conundrums around: what is the stuff that makes up the Universe?
An EPFL team is working on a smart visor that, combined with a thermal imaging camera, will help firefighters see what’s around them in real time, even at night and in smoke.
It’s time to shell-ebrate!
A tortoise that lost most of its shell in a forest fire got a 3D-printed prosthetic replacement, thanks to a team of specialists in Brazil, according to a press release translated by The Huffington Post.
A 195-year-old discovery is behind a new system that will save vehicles hundreds of litres of fuel and reduce their carbon emissions by as much as 1,000 tonnes per year.
A drone start-up is going to counter industrial scale deforestation using industrial scale reforestation.
BioCarbon Engineering wants to use drones for good, using the technology to seed up to one billion trees a year, all without having to set foot on the ground.
EPFL spin-off Gamaya has just raised 3.2 million francs for its agricultural drone system. The system combines a miniature hyperspectral camera and artificial intelligence to give farmers very precise information on the health of their crops. It can also be used to ensure fertilizer, pesticides and other treatments are used sparingly.
Overuse of antibiotics in livestock can spread drug-resistant microbes — via farm workers or even breezy weather. But there’s more than one reason stay upwind of drugged cattle.
In hunting down delicious fish, Flipper may have a secret weapon: snot.
Dolphins emit a series of quick, high-frequency sounds — probably by forcing air over tissues in the nasal passage — to find and track potential prey.

A surprising 60-year boom in global octopus, squid and cuttlefish numbers points to long-term changes taking place in the world’s oceans, scientists say.
Research published in Current Biology today shows a steady increase in the world cephalopod population — the class of molluscs comprising octopus, squid and cuttlefish — since the 1950s, at a time of increased fishing, growing pollution and ocean warming.
A relationship that has lasted for 100 million years is at serious risk of ending, due to the effects of environmental and climate change. A species of spiny crayfish native to Australia and the tiny flatworms that depend on them are both at risk of extinction, according to researchers from the UK and Australia.
Recently discovered evidence of carbonates beneath the surface of Mars points to a warmer and wetter environment in that planet’s past. The presence of liquid water could have fostered the emergence of life.
The hunt for signs of alien life in the solar system may be much tougher than researchers had thought, thanks to the damaging effects of radiation.
Two separate studies suggest that galactic radiation would quickly degrade biological material on the surface of Mars and Jupiter’s ocean-harboring moon Europa, two of the prime targets in the search for past or present extraterrestrial life.
Mysterious high-rise clouds seen appearing suddenly in the martian atmosphere on a handful of occasions may be linked to space weather, say Mars Express scientists.
Amateur astronomers using telescopes on Earth were the first to report an unusual cloud-like plume in 2012 that topped-out high above the surface of Mars at an altitude around 250 km. The feature developed in less than 10 hours, covered an area of up to 1000 x 500 km, and remained visible for around 10 days.
When a powerful “superflare” from the sun scoured the solar system more than 1,200 years ago, it apparently had little effect on Earth’s inhabitants — but today’s astronauts wouldn’t be so lucky, scientists said. New research suggests that an event of that magnitude would greatly endanger current plans for space travel, with astronauts standing a good chance of receiving lethal doses of radiation.
Giant flare-ups from the young sun might have kept early Earth warm – and any life nicely fertilised. By splitting inert nitrogen molecules in the atmosphere, charged particles from the sun could have sparked chemical reactions that heated the planet and could be the precursor for life.
