From Cain and Abel and the Brothers Karamazov to Cinderella, the warmth and support provided by siblings has hardly been taken for granted. Now, researchers have found that children who moan about their brothers and sisters may have good reason to complain: the more siblings teenagers have, the more it hits their happiness, they claim. A study of secondary schoolchildren in the US and China found that those from larger families had slightly poorer mental health than those from smaller families. The greatest impact was seen in families with multiple…

Giganto, largest ever primate, died out due to diet change, say scientists
It was the largest primate ever to have roamed the Earth, but just why – and when – our distant cousin “giganto” ended up extinct has been something of a mystery. Now researchers say the enormous ape was victim of an unfortunate choice of food when its preferred snacks became scarce. Gigantopithecus blacki roamed mainland south-east Asia 2 million years ago, with estimates suggesting it was three metres tall and weighed 200-300kg – roughly three to four times a human’s weight. Previous studies have shown giganto’s range decreased considerably by…
Moon’s resources could be ‘destroyed by thoughtless exploitation’, Nasa warned
Science and business are heading for an astronomical clash – over the future exploration of the moon and the exploitation of its resources. The celestial skirmish threatens to break out over companies’ plans to launch dozens of probes to survey the lunar landscape over the next few years. An early pioneer – Peregrine mission one – is set for launch this week. The aim of this extraterrestrial armada – largely funded through Nasa’s $2.6bn Commercial Lunar Payload Services (CLPS) initiative – is to survey the moon so that minerals, water…
Academic paper based on Uyghur genetic data retracted over ethical concerns
Concerns have been raised that academic publishers may not be doing enough to vet the ethical standards of research they publish, after a paper based on genetic data from China’s Uyghur population was retracted and questions were raised about several others including one that is currently published by Oxford University Press. In June, Elsevier, a Dutch academic publisher, retracted an article entitled “Analysis of Uyghur and Kazakh populations using the Precision ID Ancestry Panel” that had been published in 2019. The study by Chinese and Danish researchers used blood and…
WHO requests details about respiratory illness clusters in parts of China
The World Health Organization has asked China for details about a rise in respiratory illnesses that has been reported in northern parts of the country, particularly among children. Epidemiologists have warned that as China heads into its first winter since the lifting of zero-Covid restrictions, natural levels of immunity to respiratory viruses may be lower than normal, leading to an increase in infections. Several countries, including the US and the UK, experienced large waves of respiratory viral infections in the first winter after Covid restrictions were lifted as people had…
China fuels global surge in mpox cases as LGBTQ+ stigma hampers response
China is fuelling a global surge in mpox cases, accounting for the majority of new cases reported in September, according to the World Health Organization. The number of weekly cases reported globally increased by 328% in the week to 10 September, data shows. Most of that rise came from China, where more than 500 new cases were reported in August. The WHO said China was experiencing “sustained community transmission” of the virus, which was first detected as an imported case in September last year. Mpox was previously known as Monkeypox…
US seeks to extend longstanding scientific research agreement with China
The US is seeking a six-month extension to a decades-old science and technology agreement with China so that it can undergo negotiations with Beijing to “strengthen” the pact, the state department has said. The landmark deal, signed when Beijing and Washington established diplomatic ties in 1979 and renewed about every five years since, has led to the geopolitical rivals cooperating across a range of scientific and technical fields. But concerns about China’s growing military prowess and theft of US scientific and commercial achievements have prompted questions in Washington about whether…
Warnings of scientific ‘suicide’ as US-China research collaboration hangs in balance
In 1991, about 25 babies in every 100,000 in the United States were born with spina bifida, a birth defect that can cause paralysis and brain damage. Fifteen years later, the likelihood had fallen by nearly one-third. That so many babies could be spared such a fate was thanks to the simple discovery that folic acid supplements could dramatically reduce the chances of neural tube defects, which cause spina bifida and anencephalus, a rarer condition. It was “one of the great successes of public health,” according to Tom Frieden, a…
Nerves build as India moon mission prepares to make first successful south pole landing
As it was announced that Russia’s first lunar mission in 47 years had crashed on to the moon, India’s own mission, the Chandrayaan-3 lander, moved into prelanding orbit. News on Sunday of the Russian failure was met with excitement and nervousness in India: excitement that India was now poised to win the race to become the first country to land a craft on the moon’s south pole; nervousness that its mission could also go horribly wrong at the last moment. Indian space officials have been at pains to downplay any…
‘Not always king’: fossil shows mammal sinking teeth into dinosaur
Whether they had sharp teeth, vicious claws or were simply enormous, dinosaurs were creatures to be feared. But a newly identified fossil shows that, at least sometimes, the underdog bit back. Experts revealed the 125m-year-old fossil that froze in time after being taken on by a small mammal a third of its size. They are tangled together, the mammal’s teeth sunk into the beaked dinosaur’s ribs, its left paw clasping the beast’s lower jaw. Researchers said the discovery challenged a long-held view of early mammals as “fodder” for dinosaurs. Dr…
