When people interact in an Internet community, they experience higher levels of trust initially. But as time passes and more information comes to light about other users, they are more wary, according to new Stanford research.

The proverbial broken heart threatens anyone brave enough to put his love and trust into someone else’s hands. It’s that emotional phenomenon your mother warned you about during infamous teen angst years. But what happens when a broken heart is more than just a flood of feelings and actually enters into a physical, sometimes life-threatening state?
Asthma attacks can be scary and painful—yet some of them may be avoidable if asthma sufferers can alter their expectations. Evidence is mounting that believing an odor or activity will trigger an asthma attack is sometimes all it takes to induce real physical symptoms.
Where did the thief go? You might get a more accurate answer if you ask the question in German. How did she get away? Now you might want to switch to English. Speakers of the two languages put different emphasis on actions and their consequences, influencing the way they think about the world, according to a new study. The work also finds that bilinguals may get the best of both worldviews, as their thinking can be more flexible.
Lolloping on their pectoral fins to forage for food over ground, mudskippers have adapted to life in and out of water. Now, slow-motion X-ray video shows how these amphibious fish use a mouthful of water like a tongue to capture and swallow food on land – a finding that may offer a glimpse into how fleshy-tongued terrestrial tetrapods evolved from fish 400-350 million years ago.

Spiders can customise their webs to make sure they get the diet they need, new research suggests.

When Charles Darwin visited South America on HMS Beagle in the 1830s, he discovered fossils of several hefty mammals that defied classification, such as Macrauchenia, which looked like a humpless camel with a long snout; or Toxodon, with a rhino’s body, hippo’s head and rodent-like teeth — which he described as “perhaps one of the strangest animals ever discovered”.
Today's rich variety of beetles may be due to an historically low extinction rate rather than a high rate of new species emerging, according to a new study. These findings were revealed by combing through the fossil record.
A newly discovered crocodilian ancestor may have filled one of North America's top predator roles before dinosaurs arrived on the continent. Carnufex carolinensis, or the "Carolina Butcher," was a 9-foot long, land-dwelling crocodylomorph that walked on its hind legs and likely preyed upon smaller inhabitants of North Carolina ecosystems such as armored reptiles and early mammal relatives.
A 17-million-year-old beaked whale fossil is helping researchers solve a puzzle about the likely birthplace of humanity in East Africa, a new study finds.

Scientists have raised concerns about a large, rapidly thinning glacier in Antarctica, warning it could contribute significantly to rising sea levels.
What little ice remains on Mercury and Mars is mostly confined to the planets’ poles, as one would expect, because the sun shines the least in those regions. Not so on the moon. Much of the moon’s ice, which lurks beneath the surface, is found in an area 5.5° away from the north pole and in a matching region 5.5° from the south pole, scientists announced here this week at the Lunar and Planetary Science Conference. The data suggest that in the past, the moon’s axis of rotation—and hence its poles—shifted.
Natural tunnels known as lava tubes could safely house permanent bases on the Moon, scientists have said.
Could water have carved channels on Mars as recently as 500,000 years ago? If that’s the case, it would boost the case for relatively recent life on the Red Planet.
A Nasa spacecraft orbiting the Red Planet has detected a mysterious aurora that reaches deep into the Martian atmosphere.

With recent news headlines proclaiming that dozens of people have been selected as finalists for a Martian astronaut corps, it might seem like a trip to this alien world might finally be close at hand.

Dressed in loincloths and speaking an unknown language, the Mashco-Piro, one of the last isolated peoples on Earth, are increasingly venturing out of their forests in Peru — to the government’s distress.
