Cables underneath New York City are teeming with entangled quantum particles of light thanks to Qunnect, a company that has spent a decade working on building an unhackable quantum internet
Models show that as the Atlantic Meridional Overturning Circulation gets weaker, the Gulf Stream will drift northwards. There are signs that this is already happening, and a more abrupt shift could warn of more severe climate impacts
NASA’s DART mission slammed into the small asteroid Dimorphos in 2022, and the impact slowed its orbit around the larger Didymos – and also the pair’s path around the sun
The science writer delves into the vast subject of consciousness in his new book A World Appears – and draws some surprising conclusions, finds Grace Wade
Looking for molecular evidence of life on other worlds is tricky, but a test based on the reactivity of carbon compounds could be a useful indicator
The Alzheimer’s field is being turned on its head as mounting evidence points to the disease beginning outside the brain many years before symptoms start. This may mean we have to totally rethink how we approach preventing and treating the condition
Persistent inflammation in the gut, lungs and skin might lead to Alzheimer's disease, but lifestyle choices - from getting vaccinated to eating well - can keep inflammation under control
Horses use their larynx to make two sounds simultaneously, so they are effectively singing and whistling at the same time
What do a 20th-century physicist, an 18th-century statistician and an ancient Greek philosopher have in common? They all knew how to extrapolate with incredible accuracy. Columnist Jacob Aron explains how to combine their methods to improve your ability to guess
The latest in Adrian Tchaikovsky’s Children of Time series is out this month, along with a speculative retelling of Moby-Dick and a forgotten classic from 1936
A new book from Rebecca Solnit, promising to bring us hope in these “difficult times”, is among our pick of popular science titles out this month – along with a guide on how to talk to AI, and a look at modern warfare
Since 2014, the planet has been warming by about 0.36°C per decade, according to an analysis of five temperature datasets, raising fears that climate tipping points could be crossed earlier than expected
Secret-keeping evolved to maintain social harmony, but it can weigh heavily on us when we can’t stop thinking about them. So, what is the best way to deal with things that we don't want anyone else to know?
Microplastics have been found accumulating everywhere from our water to our body tissues, but many of the claims have come under fresh scrutiny. Chelsea Whyte cuts through the research to tell you whether you really need to worry
Physicists are scrambling to understand why dark energy is weakening. In a surprising twist, we must now reconsider the possibility that our reality contains extra dimensions.
Black holes that turn matter into energy could explain dark energy and answer two other cosmic questions. Now, the challenge is to find them
My latest maths column is about how you can get better at guessing - and why that's an important skill to have in the modern world www.newscientist.com/article/2518...
Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the universe in a completely different way than we do. Physicist Daniel Whiteson explores what that could tell us about physics and ourselves
Global warming has accelerated by 2x.
As a result, we could breach the Paris 1.5°C limit as early as this year, raising the threat of crossing tipping points like ice sheet collapse & Amazon dieback www.newscientist.com/article/2518...
Everyone knows Yuri Gagarin as the first person to go to space. But was he? Physicist Vladimir Brljak tells the tale of the intrepid balloonists who first flew beyond the blue terrestrial sky, challenging the definition of where our world begins to end
The books, TV, games and more that New Scientist staff have enjoyed this week
If up to 20 per cent of us really do score highly on traits related to psychopathy, we are going to need all the help offered by a compelling new book. Start by admitting your own dark traits, finds Sally Adee
The drug rapamycin has been held up for its life-extending properties, but whether this treatment – or fasting – actually adds years to your life isn't guaranteed
The discovery of bright yet stable pigments is vanishingly rare, making them hugely valuable. Now chemist Mas Subramanian is unpicking the atomic code of colour and homing in on our most-wanted hue
Superconducting computing circuits were briefly heralded as the future of computing in the 1980s. Columnist Karmela Padavic-Callaghan visits a quantum chip foundry where one company is betting this technology’s second act will revolutionise quantum computers
Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story
From the cost of childcare to the housing crisis, there’s no shortage of explanations for the dramatic global fall in the number of babies being born. These analyses, though, are all missing something, says cognitive and evolutionary anthropologist Paula Sheppard
The microbes that live in our mouth and gut may influence whether an allergic reaction to peanuts is mild or life-threatening, and could be harnessed to ward off a severe attack
