When stars like our Sun die, they tend to go out with a whimper and not a bang — unless they happen to be part of a binary (two) star system that could give rise to a supernova explosion. Now, for the first time, astronomers have spotted the radio signature of just such an event ...
Bees are among the most important insects on Earth — vital pollinators of our crops and significant contributors to human societies for thousands of years. While visiting various plants, bees need to figure out the best flowers so they can be the most efficient foragers possible, and communicate this to their hive. But there’s much ...
How did we get here? Where are we going? And how long will it take? These questions are as old as humanity itself, and, if they’ve already been asked by other species elsewhere in the Universe, potentially very much older than that. They are also some of the fundamental questions we are trying to answer ...
How old are butterflies, and where did they evolve? And perhaps more importantly, how and when did they reach the isolated continent of Australia? Answers to these simple questions have baffled scientists for decades. Until recently, we had very little idea when butterflies evolved, and hypotheses concerning their place of origin were largely educated guesses. ...
Physicists believe most of the matter in the universe is made up of dark matter, an invisible substance that we only know about by its indirect effects on the stars and galaxies we can see. We’re not crazy! Without this “dark matter,” the universe as we see it would make no sense. But the nature ...
An international team of researchers has recovered DNA from the owner of a deer-tooth pendant jewelry that was buried inside a remote Siberian cave for tens of thousands of years. In research published in Nature, Elena Essel of the Max Planck Institute for Evolutionary Anthropology in Germany and colleagues detail how they developed a new ...
Many visitors to Arnhem Land in the Northern Territory are struck by the magnificent cliffs, stunning bird life, and extraordinary rock art. Some may know this landscape includes the earliest evidence of human occupation in what is now Australia, at Madjedbebe, where signs of habitation have been dated to 65,000 years ago. Most people, however, ...
Humans make decisions using statistical information every day. Imagine you’re selecting a packet of jellybeans. If you prefer red jellybeans, you will probably try to find a packet that shows the most red (and less of the dreaded black ones) through the small window. But what about animals like giraffes? Since you can’t see all ...
The technology to decode our thoughts is drawing ever closer. Neuroscientists at the University of Texas have, for the first time, decoded data from non-invasive brain scans and used them to reconstruct language and meaning from stories that people hear, see, or even imagine. In a new study published in Nature Neuroscience, Alexander Huth and ...
Hunter-gatherers took shelter from the ice age in Southwestern Europe, but were replaced on the Italian Peninsula according to two new studies, published in Nature and Nature Ecology & Evolution. Modern humans first began to spread across Eurasia approximately 45,000 years ago, arriving from the near east. Previous research claimed these people disappeared when massive ...
