Simulations of Australopithecus hominins’ anatomy suggest that when they gave birth, they may have exerted tremendous pressure on their pelvic floors, putting them at risk of tearing
There are a few simple things you can do to make your digital life much more secure, says cybersecurity expert Jake Moore - follow these tips to tighten up your passwords
A trumpet-shaped, single-celled organism seems able to predict one thing will follow another, hinting that such associative learning emerged long before multicellular nervous systems
A growing body of research shows that we tend to discount a person’s good deeds if they stand to benefit from them. Columnist David Robson explores where this instinct comes from – and whether we should resist it
The errors that quantum computers make are holding the technology back. But recent progress in quantum error correction has excited many researchers
Toys powered by AI show a worrying lack of emotional understanding. But we need to understand the risks and benefits of the technology so the industry can be regulated, not outright banned
Body mass index (BMI) is used as a global standard for measuring health, but does it actually tell you anything about how healthy you are on an individual level? Carissa Wong explains the problems with this flawed tool
The story of a wildflower that adapted to a severe drought in California raises hopes that evolution will come to the rescue of species hit by climate change, but there are limits
Two popular quantum computing algorithms for problems in chemistry may have very limited use even as quantum hardware improves

Samantha King and Gavin Weedon's new book Protein digs deep into the nutrient's role in our health. But can it tell you how much you should be eating? Alexandra Thompson explores
Deep canyons in the Andes are the perfect location to catch the most energetic particles in the universe. Carlos Argüelles-Delgado reveals how these intergalactic envoys could help prove the quantum nature of gravity
The reliable internet connections provided by Starlink offer a huge advantage on the battlefield. But as access is dependent on the whims of controversial billionaire Elon Musk, militaries are looking to build their own version
The "world smells different" for people with Parkinson's disease, a discovery that could help doctors spot the condition sooner
Two mass strandings involving hundreds of dolphins in Argentina probably happened because the pods were being hunted by orcas, highlighting the role of predators in these mysterious events
When New Scientist reporter James Woodford was assigned to a story about a virus designed to kill rabbits, he never expected to be accused of spreading it
Most of us don’t worry about our health in old age until we get there, but research is increasingly showing that how you live in your mid-50s can have a real impact in your 90s
Statistics that quantify a person’s predisposition to diseases such as diabetes and cancer can be reverse-engineered to reveal the underlying genetic data, prompting privacy concerns
Cortical Labs is building two data centres that will house its neuron-filled chips. The technology is still in the very early stages of development

Mushrooms have been used by ancient humans for millennia, but archaeologists have only just uncovered their pivotal role in shaping civilisation
A rapidly brightening burst of light called AT 2024wpp, or "the Whippet", is baffling astronomers. One explanation is that it is the result of an exotic star falling into a black hole
Ryan Gosling stars in the latest adaptation of an Andy Weir novel, another tale of a lone genius battling to survive in space. Bethan Ackerley thoroughly approves
Figuring out what really counts as a galaxy could give us insights into dark matter and potentially shake up astrophysics, cosmology and particle physics, says columnist Chanda Prescod-Weinstein
The speed at which artificial intelligence is gaining in mathematical ability has taken many by surprise. It is rewriting what it means to be a mathematician
An analysis of ancient and modern DNA suggests the extent of convergent evolution in different peoples around the world is even greater than we thought
US-Israeli strikes on oil facilities have caused black rain to fall on Tehran, but the black smoke filling the air is likely to be a bigger health risk
Their species name is well known, but until recently we’ve understood very little for certain about Homo habilis. Columnist Michael Marshall reveals what new fossils are telling us about the hominins that have been considered the first humans
We’re learning that frailty can quietly arrive decades before old age, with some people in their 30s or 40s unknowingly in a pre-frail state. There are surprising ways to stay strong – and it’s not all about weight training
Taking a multivitamin every day might slightly slow the rate of ageing, but the extent to which this is relevant to our health is unclear
