You know we’ve found something new and interesting when scientists don’t really know how to classify it. Using the Subaru Telescope an international team of astronomers has discovered a “super-Jupiter” so massive that it seems they’re not quite sure whether to call it a planet or a low-mass brown dwarf (in other words, a star…
A team of NASA scientists and their colleagues have found evidence from meteorites that Mars and Earth had a similar origin, but then the two planets evolved quite differently. Based on their analyses of two Martian meteorites, researchers have concluded that water in the Martian interior originated from planetary building blocks similar to those that…
China, India, South Africa and Brazil said a climate deal planned for 2020 won’t be a “new regime,” threatening confrontation with the U.S. which wants to eliminate a firewall between developed and developing nations. The four nations reined in expectations for the Durban Platform, a mandate agreed last December at United Nations treaty talks in…
Are there dark doings near the center of the Milky Way? That may be so when it comes to the collision of dark matter particles. Although such particles are invisible, we could still theoretically see the mess they make when they collide. It’s this idea that leads physicists to scour the galaxy for some glimmer…
The first farmers who swept into Europe 6000 to 7000 years ago may have grown too big for their britches—or animal skins—too fast. A new study of archaeological sites across Western Europe highlights a strikingly consistent pattern in Neolithic farmers’ communities: Their populations grew too big, too quickly, and crashed right after they peaked. “We…
As many as two thirds of the species living in our oceans may still be unknown to science, say researchers, despite the fact that their calculations indicate that there are many fewer species than previously thought. The University of Auckland researchers reckon there are actually fewer than a million marine species, of which around 226,000…
A new celestial wonder has stolen the title of most distant object ever seen in the universe, astronomers report. The new record holder is the galaxy MACS0647-JD, which is about 13.3 billion light-years away. The universe itself is only 13.7 billion years old, so this galaxy’s light has been traveling toward us for almost the…
Initial readings of cosmic ray radiation on Mars suggest it’s about the same as on the International Space Station. Now we just need a spaceship.
An international team of researchers led by Scottish scientists has discovered a brain gene that helps explains how humans pushed past apes. The gene is highly active in two areas of the brain, controlling decision-making and language abilities, with the study suggesting it could have a role in the advanced brain functions that make us human.
Neanderthals, or even older Homo erectus (“Upright Man”) might have sailed around the Mediterranean, stopping at islands such as Crete and Cyprus, new evidence suggests. The evidence suggests that these hominid species had considerable seafaring and cognitive skills. “They had to have had boats of some sort; unlikely they swam,” said Alan Simmons, lead author…
