Ripples in space-time known as gravitational waves could help reveal the secrets at the dawn of time, just moments after the Big Bang, new research suggests. And physicists say they can learn more about these primeval gravitational waves using nuclear fusion reactors here on Earth. In a new study, physicists used equations that govern how … Read more
Archaeologists in Italy are uncovering a 1,600-year-old burial ground containing the remains of infants, children and sacrificed puppies. Some of the burials have unusual features — such as a child buried with a block in their mouth, which suggests that people were afraid that they could become “revenants” — corpses revived after death, archaeologists said. … Read more
Using a new machine-learning algorithm, scientists have picked up eight extraterrestrial signals that seem to bear the hallmarks of technology. The research, published Jan. 30 in the journal Nature Astronomy, doesn’t claim to have really found proof of intelligent aliens; a brief follow-up search for the signals detected in the study turned up only silence. … Read more
Miniature, lab-grown models of the human brain’s wrinkled surface can be used to patch injuries in the brains of living rats and thus repair broken connections in the rodents’ sensory processing systems, a new study shows. Someday, such minibrains — known as brain organoids — could potentially be used to mend the brains of human … Read more
Scientists have made one of the most precise maps of the universe’s matter, and it shows that something may be missing in our best model of the cosmos. Created by pooling data from two telescopes that observe different types of light, the new map revealed that the universe is less “clumpy” than previous models predicted … Read more
As climate change transforms our world, the impacts will be felt unequally, with some animals struggling to survive and others finding ways to overcome the resulting challenges. This phenomenon is increasingly described as the “winners and losers under climate change,” said Giovanni Strona (opens in new tab), an ecologist and former associate professor at the … Read more
The Teutonic Knights were one of the great chivalric orders that emerged from the Crusades, alongside the Hospitallers and Templars, but while those other knights made their names in the Holy Land, the Teutonic Knights fought their greatest battles in Europe. In the latest issue of All About History (opens in new tab), on sale … Read more
The world’s most notorious pirates terrorized the seven seas and amassed huge riches between the 16th and 19th centuries. Many of these ship plunderers remain famous to this day, but they were very different from the often-friendly pirates seen in the “Pirates of the Caribbean” movie franchise. Many of history’s most famous pirates began as … Read more
A “replica” sword that has been part of the collection at the Field Museum in Chicago for nearly a century is actually a 3,000-year-old artifact from the Bronze Age. Curators made the shocking discovery while preparing for an upcoming exhibition called “First Kings of Europe.” The 3-foot-long (91 centimeters) bronze sword had been in storage … Read more
Young stars are surrounded by chaos: Clouds of gas, dust and ice swirl about in a so-called protoplanetary disk. And when gravity binds this material together, planets are born. Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers developed a new technique to measure and date infant exoplanets forming in these protoplanetary disks. By … Read more
