The severity of drought conditions during the demise of the Maya civilisation about one thousand years ago has been quantified, representing another piece of evidence that could be used to solve the longstanding mystery of what caused the downfall of one of the ancient world’s great civilisations.
The creation of artificial embryos has moved a step forward after an international team of researchers used mouse stem cells to produce artificial embryo-like structures capable of ‘gastrulation’, a key step in the life of any embryo.
The arrival of Europeans to the Americas, beginning in the 15th century, all but wiped out the dogs that had lived alongside native people on the continent for thousands of years, according to new research published today in Science.
Regularly drinking more than the recommended UK guidelines for alcohol could take years off your life, according to new research from the University of Cambridge. Part-funded by the British Heart Foundation, the study shows that drinking more alcohol is associated with a higher risk of stroke, fatal aneurysm, heart failure and death.
A simple potassium solution could boost the efficiency of next-generation solar cells, by enabling them to convert more sunlight into electricity.
A growing network of lakes on the Greenland ice sheet has been found to drain in a chain reaction that speeds up the flow of the ice sheet, threatening its stability.
Children as young as seven apply basic laws of physics to problem-solving, rather than learning from what has previously been rewarded, suggests new research from the University of Cambridge.
Scientists have shown in mice that skin cells re-programmed into brain stem cells, transplanted into the central nervous system, help reduce inflammation and may be able to help repair damage caused by multiple sclerosis (MS).
Astronomers have looked back to a time soon after the Big Bang, and have discovered swirling gas in some of the earliest galaxies to have formed in the Universe. These ‘newborns’ – observed as they appeared nearly 13 billion years ago – spun like a whirlpool, similar to our own Milky Way. This is the first time that it has been possible to detect movement in galaxies at such an early point in the Universe’s history.
