As early as the Stone Age, mankind started to develop a complex culture. This was triggered by interactions between different groups of hunters and gatherers, as a UZH study confirms. The researchers mapped the social network of modern hunters and gatherers in the Philippines, thereby simulating the invention of a cure. Around 300,000 years ago, ...
University of British Columbia astronomy student Michelle Kunimoto has discovered 17 new planets, including a potentially habitable, Earth-sized world, by combing through data gathered by NASA’s Kepler mission. Over its original 4-year mission, the Kepler satellite looked for planets, especially those that lie in the “Habitable Zones” of their stars, where liquid water could exist ...
A little over a year after landing, China’s spacecraft Chang’e-4 is continuing to unveil secrets from the far side of the Moon. The latest study, published on Feb. 26 in Science Advances, reveals what lurks below the surface. Chang’e-4 (CE-4) landed on the eastern floor of the Van Kármán crater, near the Moon’s south pole, ...
Astronomers have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its type. It means that a single year for this hot Jupiter — a gas giant similar in size and composition to Jupiter in our own solar system — passes in less ...
For three years, anthropologist Alan Rogers has attempted to solve an evolutionary puzzle, which seems to be the result of interbreeding. His research untangles millions of years of human evolution by analyzing DNA strands from ancient human species known as hominins. Like many evolutionary geneticists, Rogers compares hominin genomes looking for genetic patterns such as ...
The precursor of our planet, the proto-Earth, formed within a time span of approximately 5 million years, shows a new study from the Centre for Star and Planet Formation (StarPlan) at the Globe Institute at the University of Copenhagen. On an astronomical scale, this is extremely fast, the researchers explain. If you compare the solar system’s ...
Archaeologists from the Oriental Institute have discovered a lost ancient kingdom dating from 1400 B.C. to 600 B.C., which may have defeated Phrygia, the kingdom ruled by King Midas, in battle. University of Chicago scholars and students were surveying a site with Turkish and British colleagues last summer in southern Turkey called Türkmen-Karahöyük, when a ...
The Breakthrough Listen Initiative released data from the most comprehensive survey yet of radio emissions from the plane of the Milky Way Galaxy and the region around its central black hole, and it is inviting the public to search the data for signals from intelligent civilizations. At a media briefing in Seattle as part of ...
Using ESO’s Very Large Telescope (VLT), astronomers have captured the unprecedented dimming of Betelgeuse, a red supergiant star in the constellation of Orion. The stunning new images of the star’s surface show not only the fading red supergiant, but also how its apparent shape is changing. Betelgeuse has been a beacon in the night sky ...
A new study led by the University of Hawai‘i (UH) at Mānoa has helped refine our understanding of the amount of hydrogen, helium, and other elements present in violent outbursts from the Sun and other types of solar “wind,” a stream of ionized atoms ejected from the Sun. Coronal mass ejections (CME) are giant plasma bursts that ...
