The forests of the Maya Biosphere Reserve are growing rather than shrinking, because of a community-led conservation programme

Deadly stellar radiation blasts 'habitable' exoplanets every few days

Hace 15 horas 22 mins
Planets orbiting M-class red dwarf stars have been suggested as some of the most promising places to look for alien life, but now it seems powerful outbursts from the stars could render them uninhabitable

Spoofing cyberattack can make cameras see things that aren’t there

Hace 19 horas 7 mins
A targeted transmission of radio waves can disrupt what a camera detects – and the technology has the potential to fool object-detection systems into seeing things that aren’t there

Scientists are slathering reefs with antibiotics to stop coral disease

Vie, 23/09/2022 - 15:37
Researchers have resorted to applying antibiotics on corals to save Caribbean reefs from deadly disease, but there are concerns this could create antibiotic resistance in other marine animals

Robot navigates indoors by tracking anomalies in magnetic fields

Vie, 23/09/2022 - 10:05
Metal pipes beneath the floor provide enough local disturbance of Earth’s magnetic field for an autonomous robot to work out where it is and navigate around a lab

Chronic fatigue syndrome linked to almost 200 genetic variants

Vie, 23/09/2022 - 09:37
In a study of more than 2300 people with chronic fatigue syndrome, 91 per cent had these genetic variants, in a discovery that could improve diagnosis and treatment

Bowhead whales live longer thanks to mutation that also shrinks testes

Vie, 23/09/2022 - 08:59
We may have discovered one of the key reasons for the extraordinary lifespans of bowhead whales, which can live for more than 200 years

Physicists found the shortest measurement to collapse a quantum state

Jue, 22/09/2022 - 17:14
Measuring a quantum object makes it lose its odd quantum properties, and it only takes between 0.1 billionth of a second to 0.1 sextillionth of a second

Decarbonising the shipping industry will cost more than $1 trillion

Jue, 22/09/2022 - 16:30
Powering all shipping vessels with zero-emission fuels by 2050 would slash the industry's emissions, but it would require between $1 trillion and $1.4 trillion of investment

Web of blood vessels helps protect whales’ brains while swimming

Jue, 22/09/2022 - 14:00
When a whale pumps its tail up and down to swim, a wave of increased blood pressure moves from the tail to the head – but a network of vessels redirects the animal’s blood to protect the brain

These male hummingbirds evolved to be tiny so they can do cool dives

Jue, 22/09/2022 - 13:09
Male bee hummingbirds evolved to be much smaller than females, possibly because their diminutive size allows them to make faster and more elaborate courtship flights

Too many electric cars charging at night may overload electrical grid

Jue, 22/09/2022 - 11:00
As electric car ownership rises, we will need new infrastructure to avoid overwhelming electricity grids – including public charging stations and more daytime charging

Scientists who discovered cause of narcolepsy win Breakthrough Prize
