Bits of food stuck between the teeth of a two-million-year-old South African hominid show that, unlike almost all other known human ancestors, it ate tree bark and other hard foods. Australopithecus sediba’s diet was dramatically different to that of its African cousins, which tended to eat grasses and sedges. “It is an important finding, because…
Scientists at the Brookhaven National Laboratory have carried out an experiment that has recreated a form of matter that pervaded the entire universe a fraction of a second after the Big Bang – the cosmic explosion that marked the origin of the universe. The experiment produced fundamental insights into laws pertaining to all visible matter….
The discovery of life beyond Earth would shake up our view of humanity’s place in the universe, but it probably wouldn’t seriously threaten organized religion, experts say. The Bible, Koran and other sacred texts of the world’s major religions stress God’s special concern for humanity and for Earth. So the discovery of aliens — microbes…
It’s not just man’s closer primate relatives that exhibit brain power. Dolphins, dogs and elephants are teaching us a few lessons, too. Dolphin brains involve completely different wiring from primates, especially in the neocortex, which is central to higher functions such as reasoning and conscious thought. Dolphins are so distantly related to humans that it’s…
Farmers, used to betting on the weather, are changing their tactics to cope with changes in the rules of the game
Our universe could have popped into existence 13.7 billion years ago without any divine help whatsoever, researchers say. That may run counter to our instincts, which recoil at the thought of something coming from nothing, but scientists say, we should trust the laws of physics. In the very weird world of quantum mechanics, which describes…
Researchers have come up with a way to glimpse the infant Universe by decoding the earliest ripples in its light. They say this can be achieved by capturing the specific radio wavelength of 21cm from the heavens. The trick is to tell the difference between 21cm waves from our galaxy and those from distant, ancient…
It’s 20 million years ago in the forests of Argentina, and Homunculus patagonicus is on the move. The monkey travels quickly, swinging between tree branches as it goes. Scientists have a good idea of how Homunculus got around thanks to a new fossil analysis of its ear canals and those of 15 other ancient primates….
Ethiopians’s long-ago genetic mixing with populations from Israel and Egypt is a legacy of the Queen of Sheba and her companions, say researchers.
The amount of water in places of the Martian mantle is vastly larger than previous estimates and is similar to that of Earth’s, scientists have found. The finding is based on the analysis of the water content of two Martian meteorites originating from inside the Red Planet. The results not only affect what we know…
