For decades, planetary geologists have speculated that glaciers might once have crept through Valles Marineris, the 2000-mile-long chasm that constitutes the Grand Canyon of Mars. Using satellite images, researchers have identified features that might have been carved by past glaciers as they flowed through the canyons; however, these observations have remained highly controversial and contested.
Astronomers tend to assume that the timing of Earth-striking meteors are completely random, but a recent analysis suggests that meteor impacts are more likely to occur at certain times of the year and at certain locations.
Geological evidence tells us that ancient Earth probably looked and felt very different from the planet we all recognize today. Billions of years ago, our world was a comparatively harsh place. Earth likely had a hotter climate, acidic oceans and an atmosphere loaded with carbon dioxide. The fact that manmade climate change, through carbon dioxide pollution, is re-introducing such hotter, acidified conditions demonstrates their intertwinement.
An ancient Egyptian mummy is sparking new questions among archaeologists, because it has one very rare feature: The blood vessels surrounding the mummy's brain left imprints on the inside of the skull.
What can DNA from the skeleton of a man who lived 2,330 years ago in the southernmost tip of Africa tell us about ourselves as humans? A great deal when his DNA profile is one of the 'earliest diverged' – oldest in genetic terms – found to-date in a region where modern humans are believed to have originated roughly 200,000 years ago.
About 210 million years ago when the supercontinent of Pangea was starting to break up and dog-sized dinosaurs were hiding from nearly everything, entirely different kinds of reptiles called phytosaurs and rauisuchids were at the top of the food chain.
Sophisticated oceangoing canoes and favorable winds may have helped early human settlers colonize New Zealand, a pair of new studies shows.
Archaeologists working at the site of Issos in the province of Hatay, Turkey, a thriving city beginning in about 545 B.C. and lasting several millennia down to the Ottoman period, have discovered an ancient music chamber according to the Hurriyet Daily News.
Whether your favorite song is Bach’s "Toccata And Fugue In D Minor" or Lil Wayne’s "Let It Rock," your brain reacts to it in the same way.
Each of us, at times, can be a procrastinator, putting off something that is hard to do or that we don’t want to do. But three researchers at Pennsylvania State University think we humans may also be precrastinators—hurrying to get something done so we can cross it off our mental to-do list, even if the rush ends up being wasteful. The researchers also claim to have coined the term “precrastination.”.
In research published on 09/28/2014 in the journal Nature Neuroscience, scientists show that neural recordings can be used to forecast when spontaneous decisions will take place. "Experiments like this have been used to argue that free will is an illusion," says Zachary Mainen, a neuroscientist at the Champalimaud Centre for the Unknown, in Lisbon, Portugal, who led the study, "but we think that interpretation is mistaken.".
Dolphins are indeed sensitive to magnetic stimuli, as they behave differently when swimming near magnetized objects. So says Dorothee Kremers and her colleagues at Ethos unit of the Université de Rennes in France, in a study in Springer's journal Naturwissenschaften – The Science of Nature. Their research, conducted in the delphinarium of Planète Sauvage in France, provides experimental behavioral proof that these marine animals are magnetoreceptive.
Until now, no one knew for sure how many lakes exist on Earth.
It looks like the heaving waves of an angry sea, and it's making its way towards an official classification - meet undulatus asperates, tipped to be the world's newest type of cloud.
