Early humans may have wiped out many turtles millions of years ago

New Scientist - Ve, 05/08/2022 - 13:41
Our hominin ancestors wiped out many land-living turtle and tortoise species starting around 5 million years ago, an analysis of the fossil record suggests

Transfusing blood from an old mouse to a younger mouse causes ageing

New Scientist - Ve, 05/08/2022 - 13:30
The transfusion led an increased number of senescent cells – which accumulate as we get older - in the young mice, suggesting that cellular ageing isn't just a case of wear and tear

How weevils have become weapons in UK's fight against invasive plants

New Scientist - Ve, 05/08/2022 - 11:00
A weevil designed to kill a problem aquatic weed is the fourth of a new wave of biological agents selected by the Centre for Agriculture and Bioscience International to tackle the economic and biodiversity scourge of invasive species

Quantum computers would be better at Wordle than classical ones

New Scientist - Ve, 05/08/2022 - 09:00
A player using a quantum algorithm will win the codebreaking game Mastermind, which has the same underlying principles as Wordle, more often and in fewer moves than someone using a classical algorithm

Can we build a quantum clock that is entirely quantum?

New Scientist - Ve, 05/08/2022 - 09:00
Quantum clocks are normally controlled by a classical control system, but to build things like tiny quantum drones that fly around delivering molecules we'll need a fully quantum approach

One in 8 people got long covid after infection early in the pandemic

New Scientist - Ve, 05/08/2022 - 01:30
Researchers estimated the prevalence of long covid using survey data from the Netherlands in the early stages of the pandemic

Vaccinating less than half of high-risk men may stop monkeypox spread

New Scientist - Gi, 04/08/2022 - 19:10
A modelling study suggests that between 5 and 47 per cent of high-risk men who have sex with men would need to be vaccinated to stop the ongoing monkeypox outbreak

European wildfires have released a record amount of carbon

New Scientist - Gi, 04/08/2022 - 18:05
The climate-warming pollution from wildfires in the first half of 2022 in the EU and UK has been on a par with the annual emissions of Cyprus

Mice produce rat sperm with technique that could help conservation

New Scientist - Gi, 04/08/2022 - 18:00
Mice containing rat cells have produced rat sperm thanks to a modification technique that could be useful for conserving endangered species or creating hybrids

Quantum computer can simulate infinitely many chaotic particles

New Scientist - Gi, 04/08/2022 - 18:00
Using just a handful of quantum bits, researchers have used a quantum computer to simulate an infinite line of electron-like particles. The technique could be used to better understand the behaviour of molecules in materials

Home screening test for oral or throat cancer has 90 per cent accuracy

New Scientist - Gi, 04/08/2022 - 16:30
To identify oral and throat cancer, lesions have to be big enough for doctors to see. A saliva test available in the US could enable much earlier diagnosis

Correction: Expanding syphilis test uptake using rapid dual self-testing for syphilis and HIV among men who have sex with men in China: A multiarm randomized controlled trial

Start-up plans 2500 artificial coral reefs to fight climate change

New Scientist - Gi, 04/08/2022 - 14:00
The Reef Company, backed by IBM and Microsoft, hopes to offset carbon emissions and support coastal economies by restoring coral reef ecosystems

E. coli that is recoded to be virus resistant may aid drug production

New Scientist - Gi, 04/08/2022 - 13:35
Changing Escherichia coli's genetic code may enable the recoded bacterium to be grown in large vats for drug production, without the risk of a viral infection upending the process

Experimental earphone can ‘hear’ commands user is silently mouthing

New Scientist - Me, 03/08/2022 - 23:53
An earbud uses artificial intelligence to interpret commands someone mouths without speaking by tracking changes in the shape of their ear canal

Mild exercise halts cognitive decline in people at risk of Alzheimer's

New Scientist - Me, 03/08/2022 - 23:14
For people with mild cognitive impairment, stretching or other light exercise for just 2 hours a week can prevent further cognitive decline

Pitcher plants use raindrop impacts to fling insects into their trap

New Scientist - Me, 03/08/2022 - 22:03
Raindrops trigger a predatory diving board that cannonballs insects into a pool of digestive fluids

Using hand gestures can improve your experience of video calls

New Scientist - Me, 03/08/2022 - 21:00
Signals, such as putting your hand over your heart to signify empathy or thumbs up to show you agree, seem to improve people’s experience of video calls more than typing words or using emojis

JWST has caught two galaxies smashing together and sparking starbursts

New Scientist - Me, 03/08/2022 - 20:16
Two glittering galaxies 275 million light years away smash together and spur star formation in an amazing new image from the James Webb Space Telescope

Untangling life's molecular mysteries using AI is a welcome advance

New Scientist - Me, 03/08/2022 - 20:00
Artificial intelligence has turned its power on deciphering the complex structures of proteins, the substances behind many vital processes in cells. It is a great boost for biology and, ultimately, wider society
