Leonardo da Vinci may have been prevented from finishing the Mona Lisa after a severe fainting episode left him with nerve damage and a ‘claw’ hand. A new study claims the Renaissance master was unable to hold a paintbrush because of the injury. A portrait of the artist shows his right arm bundled in clothing

Vegetables sold by California-based startup Iron Ox might be organic, but the farmer cultivating them is far from it. The company behind the robotic and hydroponic farming system is now taking the first step towards going to market in California. According to a report from The Verge, Iron Ox is partnering with Bay Area produce purveyors Bianchini’s

Older bees pass on immunity-boosting molecules to younger bees in their hives via the royal jelly they share. The bees can make them resistant to diseases in this jelly which larvae feed on, to give the hive a collective immune system. It means that the honeybees nourish the young, essentially meaning that the hive has

A flexible, snakelike robot could serve as a vital lifeline for bringing the northern white rhino back from the brink of extinction. Scientists at the University of California San Diego (UCSD) have partnered with the San Diego Zoo to develop the unique device, which they believe could assist with the artificial reproduction process for rhinos. The northern white rhino

Adaptation is an integral part of any species survival, but rarely does that evolution involve becoming impervious to man-made pollution. In a new report, researchers chronicle how the Gulf killifish developed an unlikely resistance to massive levels of pollution found in the natural habitat, the Houston Ship Channel. ‘Most species don’t survive radically altered environments,’

The genetic diversity of narwhals is strikingly low compared to other Arctic creatures and many less successful species, scientists have revealed. Researchers who sequenced their genome are surprised the trait appears to be having for no impact on their survival, as they continue to thrive. It’s contrary to what is usually the case in biology,

Cooking pork to 63°C is best for juiciness, tenderness and flavour, according to scientists. Average consumers consistently rated pork cooked to 63°C (145°F) as superior to joints cooked to 71 °C (160°F), and 82°C (180°F) in a new study. This was irrespective of the ‘quality’ of the meat or its pH, long thought to be

The UK will need around 7,500 offshore wind turbines to meet a carbon emissions target of zero by 2050, the Committee on Climate Change said. This compares with the current 1,900, including those at the Robin Rigg wind farm in the Solway Firth, pictured. It would mean wind turbines being built on up to 2 per cent

Fears raised about miscarriages of justice and unsolved crimes A crisis in forensic science has brought some of the country’s largest private laboratories to the brink of collapse, risking miscarriages of justice, an inquiry has warned. The House of Lords science and technology committee has called for urgent reforms to forensic science provision, warning that declining standards

Scientists extract proteins from a molar to uncover details of mysterious species’ origins A human jawbone found in a cave on the Tibetan plateau has revealed new details about the appearance and lifestyle of a mysterious ancient species called Denisovans. The 160,000-year-old fossil, comprising a powerful jaw and unusually large teeth, suggests these early relatives would
