Humans were apex predators for two million years

Credit: Dr. Miki Ben Dor Researchers at Tel Aviv University were able to reconstruct the nutrition of stone age humans. In a paper published in the Yearbook of the American Physical Anthropology Association, Dr. Miki Ben-Dor and Prof. Ran Barkai of the Jacob M. Alkov Department of Archaeology at Tel Aviv University, together with Raphael Sirtoli of Portugal, show that humans were an apex predator for about two million years. Only the extinction of larger animals (megafauna) in various parts of the world, and the decline of animal food sources toward the end of the stone age, led humans to gradually increase the vegetable element in their nutrition, until finally they had no choice but to domesticate both plants and animals - and became farmers.

Smartphone users more likely to grind their teeth or have poor sleep

People who can t handle any time without social media apps on their smartphone are more likely to grind their teeth and struggle to fall asleep, according to a new study. Researchers at Tel Aviv University compared the behaviour of people using normal smartphones to those with kosher phones which are stripped of most apps. Kosher phones are used by Israel s ultra-orthodox communities, with almost all apps, including social media, removed so the user can have internet access and make phone calls without falling foul of strict religious practices. This gave researchers a good opportunity, as it allowed them to study and compare the sleeping habits and patterns of those with both types of device.

Using a new X-ray technique, scientists in The Netherlands managed to digitally unfold a 17 th century ‘locked letter’ – a letter which had been folded into its own envelope – and read its contents without damaging the paper. They were probably relieved when they got to the salutation and it didn’t begin with “Dear John,”. To stop the annual destruction of 4 billion male chicks – useless to farmers because they can’t lay eggs, the Israeli ag-tech startup eggXYt has found a way to use CRISPR gene editing to make chickens lay sex-detectable eggs so those destined to be males can be removed and sent to groceries instead. If your breakfast eggs seem to be crowing as they run, blame these scientists.
