The drug rapamycin seems to have more or less the same life-extending effect as restricting calories, according to the largest study yet of longevity in different vertebrate species. Scientists are investigating whether interventions like dietary tweaks and exercise could help us live longer while reducing the health impacts of ageing.

Even memories that we have forgotten seem to guide our actions, which could tell us more about how they are stored in the brain. “People intuitively think of memory as something we can recall and wax poetic about,” says Nick Turk-Browne at Yale University, who wasn’t involved in the work. “But we don’t spend most of our days sitting around remembering the past. We’re working, and being parents and having fun, and our memory has this ever-present influence on our behaviour.

Stark new satellite data reveal that the Colorado River basin has lost huge amounts of groundwater over the last few decades, with some research suggesting that this groundwater could run out by the end of the century. But is that really the case? And if so, what could be done to prevent that happening? While groundwater is being depleted, it's unlikely the water will ever run out completely.

Scientists have identified a never-before-seen species of dinosaur called the dragon prince — a prehistoric predator that set tyrannosaurs on the path to ruling Earth. This newly discovered relative of Tyrannosaurus rex came to light after researchers re-examined fossils found in Mongolia. Its existence sheds light on the story of tyrannosaur dinosaurs and how they evolved and spread.

Onderzoekers hebben ontdekt dat zeekatten, een soort inktvissen, communiceren met een dansmove van het befaamde discoliedje Stayin’ Alive van de Bee Gees. Maar dat is niet het enige danspasje van de tienarmige discoliefhebbers. Zeekatten zwaaien met hun expressieve armen en versturen zo vier verschillende, dansachtige signalen. Daarmee zouden ze visueel en via vibraties kunnen communiceren.

Cockatoos in Sydney, Australia, have learned to use public water fountains by twisting a handle, despite how difficult they are for birds to operate. It seems to be a behaviour they copy from each other. Sulphur-crested cockatoos (Cacatua galerita) have already learned how to open waste bins in eastern Sydney, leading to a battle of wits as humans come up with ways to keep their bins closed and the cockatoos again work out how to open them.

Long before the Great Wall of China was constructed, other monumental walls were built across the Eurasian steppes – but they weren’t designed to defend against Mongol armies. Recent excavations reveal that they were erected to control movement of people or demonstrate power, much like border walls today. The Great Wall of China spans many thousands of kilometres, the longest stretch running some 8850 kilometres.

Onderzoekers hebben mogelijk een nieuwe dwergplaneet ontdekt aan de rand van ons zonnestelsel. Deze ontdekking trekt het bestaan van een verborgen negende planeet, Planeet X, in twijfel. De nieuwe potentiële dwergplaneet bevindt zich in de buitenste regionen van ons zonnestelsel, in een baan voorbij Neptunus. De aanwezigheid van dit object zet vraagtekens bij het bestaan van een hypothetisch hemellichaam dat bekendstaat als Planeet 9 of Planeet X.

Your sex, ethnicity and level of education may influence how long you live, but also the pace at which your body ages. There has been growing recognition over recent years that ageing doesn’t progress at the same rate in different people, and factors such as stress, poor diet and smoking can accelerate it.

There has been growing recognition over recent years that ageing doesn’t progress at the same rate in different people, and factors such as stress, poor diet and smoking can accelerate it. To find out more, Dan Belsky at the Columbia University Mailman School of Public Health in New York and his colleagues analysed data…
