TikTok and Chinese parent ByteDance were told in April they had until January next year to divest TikTok in the US or face the prospect of the app being banned ...

Drugs used to treat HIV are to be trialled in people with incurable multiple brain tumours. Scientists think ritonavir and lopinavir could shrink tumours in patients with neurofibromatosis 2 (NF2), a genetic condition where tumours grow along nerves. The tumours are normally non-cancerous but can cause symptoms such as balance problems, hearing loss and ringing in the ears. If they ...

Name any major tech brand – from Google to Amazon to Tesla to ChatGPT – and the chances are Nvidia is involved in some way.

Autonomous vehicles are involved in fewer accidents than cars driven by humans, researchers from the University of Central Florida have found. However, although the research generally showed self-driving cars to be safer, it did discover ...

With help from artificial intelligence, researchers have identified a biological signature of Parkinson’s disease they hope could lead to a simple blood test for the condition at least seven years before symptoms appear. A predictive test for Parkinson’s could be game changing. The progressive condition affects more than 150,000 people in the UK and is currently the world’s fastest-growing neurodegenerative ...

Microsoft has been dramatically toppled as the world’s most valuable public company. Nvidia, which had only overtaken Apple for the number two spot earlier this month, dethroned Microsoft during trading on Tuesday as its shares rose by more than 3%.

Microplastics have been found in penises for the first time, with scientists raising questions about their impact on sexual health. A study, published in science journal Nature, assessed the tissue from six men who had undergone surgery treating erectile dysfunction. In 80% of the samples, seven types of microplastics were identified, with some as small as two micrometres – or ...

Tesla Cybertruck buyers have been reporting delivery delays due to an issue with the vehicle’s windscreen wipers. Tesla’s Cybertruck is a stainless steel electric vehicle that costs between $57,390 (£45,170) and $96,390 (£75,870). Owners pre-order it directly from Tesla and then wait for it to be delivered. Over the weekend, however, buyers waiting for their delivery were told the trucks ...

A new genetic therapy has been developed that could reverse giant, debilitating moles that accompany a rare skin condition. Congenital melanocytic naevus syndrome, or CMN for short, sees children born with up to 80% of their body covered in big, painful or itchy moles. They are caused by genetic mutations acquired in the womb – and in some cases, these ...
