From John Brockman at Edge.org: Over the years I’ve had the privilege to work with some of the more interesting thinkers of our time, individuals who, through their research in biology, physics, psychology, computer science, provide us with the evidence-based results that are the basis of the most reliable method of our knowledge about who…
Much has been made of our ancestors “coming down out of the trees,” and many researchers view terrestrial bipedalism as the hallmark of “humanness.” After all, most of our living primate relatives—the great apes, specifically—still spend their time in the trees. Humans are the only member of the family devoted to the ground, living terrestrial…
Radiation in space might harm the brains of astronauts in deep space by accelerating the development of Alzheimer’s disease, a new study on mice suggests. The research reveals another risk that manned deep-space missions to places such as Mars or the asteroids could pose, scientists added. “This study shows for the first time that exposure…
NASA’s battle cry behind the small armada of orbiters, landers and rovers dispatched to Mars is “follow the water!” Where there’s water, there could be life, which needs a solvent like water to assemble the complex macromolecules needed for living systems. Mars is covered with geological evidence that it was once a soggy planet. But…
Advocates of manned space flight have long argued that propelling people into orbits has a public appeal unmatched by robotic missions. That was true when astronauts were racing to the moon, but since the Apollo program ended 40 years ago unmanned exploration has provided almost all of our extraterrestrial excitement – at a far lower…
An ambitious British plan to search for minute forms of life in an ancient lake beneath Antarctica’s ice has been suspended because of technical problems, the scientist leading the project said. In a move that clears the way for U.S. and Russian teams to take the lead, Professor Martin Siegert said technical problems and a…
The first truly Earth-like alien planet is likely to be spotted next year, an epic discovery that would cause humanity to reassess its place in the universe. While astronomers have found a number of exoplanets over the last few years that share one or two key traits with our own world — such as size…
Just outside of Jerusalem, archaeologists have discovered a cache of vessels and figurines inside a 2,750-year-old temple that could provide a rare window into religious rituals of the period, the Israeli Antiquities Authority announced. The finds were uncovered at Tel Motza, an archaeological site being excavated ahead of the expansion of Highway 1, the main…
Lack of rain has left many rivers at low levels unseen for decades, and while this creates problems for river commerce, it also offers an occasional treasure trove of history. For example, a rock containing what is believed to be an ancient map has emerged in the Mississippi River in southeast Missouri, with etchings that may be 1,200 years old.
This year has been a spectacular one for exoplanets. New discoveries and new insights have truly pushed the gateway to other worlds even further open. In the past 12 months we’ve gained increasingly good statistics on the incredible abundance of planets around other stars and their multiplicity. We also finally seem to have evidence that…
