In the early 1800s, Denmark’s government, medical community, church leaders and school teachers all united to promote the new smallpox vaccine, which led to a remarkably quick elimination of the disease in the capital
Members of the New Scientist Book Club give their take on Sierra Greer's award-winning science-fiction novel Annie Bot, our read for February – and the needle swings wildly from positive to negative
In this extract from the February read for the New Scientist Book Club, we meet the protagonist of Tim Winton’s Juice, driving across a scorched landscape in a future version of Australia
The New Scientist Book Club's February read is Tim Winton's novel Juice, set in a future Australia that is so hot it is almost unliveable. Here, the author lays out his reasons for writing it – and why he doesn't see it as dystopian
Elizabeth Hohmann is very interested in faeces, and spends her days sifting through stools to find those that could make the biggest difference to other people's health
Interval cancers are aggressive tumours that grow during the interval after someone has been screened for cancer and before they are screened again, and AI seems to be able to identify them at an early stage
A reanalysis of twin data from Denmark and Sweden suggests that how long we live now depends roughly equally on the genes we inherit, and on where we live and what we do
Shrinking sea ice has made life harder for polar bears in many parts of the Arctic, but the population in Svalbard seems to be thriving
Adults with kidney cancer who received faecal microbiota transplants on top of their existing drugs did better than those who had placebo transplants as their add-on intervention
Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct
Feedback has been informed about a "global telepathy study" which is currently taking place, but isn't entirely convinced about its merits
While snakes and ladders is purely a game of chance, there is a way to add some strategy, says mathematician Peter Rowlett
From health tech developers to influencers, our health is being monetised – and we need to be aware of what's going on, says Deborah Cohen
The books, TV, games and more that New Scientist staff have enjoyed this week
Susan Wise Bauer's The Great Shadow investigates the effects of illness on individual lives and collective beliefs. It's a mixed bag, says Peter Hoskin
How much do you know about friction? Jennifer R. Vail's charming, if sometimes technical, "biography" of the force showcases its amazing and largely overlooked role in everything from climate change to dark matter, says Karmela Padavic-Callaghan
Many countries are debating whether to follow Australia and ban social media for younger teenagers. But with more robust evidence on its harms coming, we shouldn't be too hasty
Where is physics headed? No one knows for sure, but Beyond the Quantum by Antony Valentini is a striking new book that reminds us what a big idea really looks like, finds Jon Cartwright
The ubiquitous Epstein-Barr virus is increasingly being linked to conditions like multiple sclerosis and lupus. But why do only some people who catch it develop these complications? The answer may lie in our genetics
Thousands of years before the invention of compasses or sails, prehistoric peoples crossed oceans to reach remote lands like Malta and Australia. Doing so meant striking out in unknowable conditions. What do such crossings tell us about ancient minds?
A treasure trove of Cambrian fossils has been discovered in southern China, providing a window on marine life shortly after Earth’s first mass extinction event
Clumps of cells known as organoids are helping us to understand the brain, and the latest version comes equipped with realistic blood vessels to help the organoids live longer
Using a superconducting quantum computer, physicists created a large and complex version of an odd quantum material that has a repeating structure in time
The amount of rainfall in the southern Amazon basin has declined by 8 to 11 per cent since 1980, largely due to the impact of deforestation
The measles vaccine has prevented 60 million deaths since 2000. So why are so many children around the world missing out on it?
A newly discovered collection of neurons suggests the brain and heart communicate to trigger a neuroimmune response after a heart attack, which may pave the way for new therapies
Chemist Omar Yaghi invented materials called MOFs, a few grams of which have the surface area of a football field. He explains why he thinks these super-sponges will define the next century
An evolution-inspired framework for how quantum fuzziness gives rise to our classical world shows that even imperfect observers can eventually agree on an objective reality
Excavations at an opencast mine in Greece have uncovered two wooden objects more than 400,000 years old that appear to have been fashioned as tools by an unknown species of ancient human
A woman's fertility can be partly gauged by levels of a hormone that reflects how many eggs she has. Now, scientists have built a strip that changes colour according to levels of this hormone, which is present in period blood, into a menstrual pad
JWST has created a map of dark matter that is twice as good as anything we have had before, and it may help unravel some of the deepest mysteries of the universe
The way time ticks forward in our universe has long stumped physicists. Now, a new set of tools from entangled atoms to black holes promises to reveal time’s true nature
Solar geoengineering could halve the economic cost of climate change, but stopping it would cause temperatures to rebound sharply, leading to greater damage than unabated global warming
Columnist Helen Thomson investigates the neurological benefits of saunas, and how heat therapy can have anti-inflammatory effects throughout the body
Despite its small size, Mars seems to have a huge impact on the orbital cycles that govern Earth’s climate, especially those that cause ice ages
A drug that kills cancer cells by puncturing them comes with an additional benefit: tests in mice suggest it reduces the growth of pain-sensing nerves around tumours
An “epigenetic” adaptation could prevent large numbers of loggerhead turtles from hatching as female due to climate change – a threat that was feared to lead to population collapse
Whether it be singing, dancing or crafting, engaging in the arts is good for our health, and we're beginning to understand how this behaviour affects our biology
Two extremely damaging crop pests have interbred to create hybrids resistant to more than one pesticide that could cause serious problems in many countries
The company’s mega-constellation is having to perform a huge number of manoeuvres to prevent a collision in Earth orbit
Your chronological age can’t always tell you the state of your health, which is why biological clocks have been developed to show our risk of developing diseases or dying – but they’re not all they are cracked up to be, says columnist Graham Lawton
Many species of fungus across the world produce psilocybin, a chemical with psychedelic effects in humans, but its evolutionary purpose may be to deter mushroom-munching insects
A 5500-year-old genome recovered from human skeletal remains in Colombia may give insights into the early evolution of syphilis and its relatives
A distinct set of microbes has been identified in people with obesity, which might help spot and treat the condition early – but whether it is a cause or effect of the condition isn’t known
Long thought to have walked bipedally, like us, Australia’s extinct giant kangaroos have features that indicate they could also have bounced
A trial will finally reveal whether limiting the time teens spend on social media really does affect their mental health
Donated placentas can be processed into thin, sterilised sheets that are packed with natural healing substances and reduce scarring when applied to wounds
A striking shot of biting flies on the head of a crocodile is among the winning entries in the British Ecological Society’s annual Capturing Ecology photography competition
Women using frozen embryos as part of their IVF treatment can either choose to use a medicated cycle or their natural one to prepare their uterus for a pregnancy. Now, scientists have found that the latter option seems to carry fewer risks
Photographer Frédéric Noy's shots give an insight into life around the rainforests of Udzungwa Mountains National Park – and efforts to protect it
