AT&T apparently has an editorial section on their website. Here's an article I found particularly interesting:

Things we know now that we didn't know this time last year.

Here's a sample:

1. Domestic pigs can quickly learn how mirrors work and use them to find food.

2. Grumpy people think more clearly because negative moods trigger more attentive, careful thinking.

3. High cholesterol levels in midlife are associated with an increased risk of Alzheimer's disease and other forms of dementia later in life.

4. Analysis of Greenland ice samples shows Europe froze solid in less than 12 months 12,800 years ago, partly due to a slowdown of the Gulf Stream. Once triggered, the cold persisted for 1,300 years.

5. One mutated gene is the reason humans have language, and chimpanzees, our closest relative, do not.

6. Obesity in teenage girls may increase their risk of later developing multiple sclerosis.

7. A fossil skeleton of an Aardonyx celestae dinosaur discovered in South Africa appears to be the missing link between the earliest dinosaurs that walked on two legs and the large plant-eating sauropods that walked on all four.

8. Women who have undergone successful breast cancer treatment are more likely to experience a recurrence if they have dense breast tissue.

9. Babies pick up their parents' accents from the womb, and infants are born crying in their native dialect. Researchers found that French newborns cry in a rising French accent, and German babies cry with a characteristic falling inflection.

10. Surfing the Internet may help delay dementia because it creates stimulation that exercises portions of the brain.

34. Nearly all animals emit the same stench when they die, and have done so for more than 400 million years.

35. Previously unknown molecules called hydroxyl radicals are produced by nature and are believed to act as cleaning agents that scrub away toxic air pollution in Earth's atmosphere.

36. A new species of giant rat was discovered in a remote rainforest in Papua New Guinea. At 32.2 inches from nose to tail and 3.3 pounds, it's thought to be one of the largest rats ever found.

37. Differences in body odors produced by people who are more prone to insect bites show they have lower levels of fruity-smelling compounds in their sweat than those who are resistant to mosquitoes.

38. A chemical component in broccoli can protect the lining of arteries from blockage that leads to angina, heart attack and stroke.

39. The length, curl and texture of a dog's fur are controlled by only three genes.

40. The speed of U.S Internet broadband lags far behind other industrial nations, including Japan, Finland, South Korea, France and Canada.

41. Polar bear skulls have shrunk 2 percent to 9 percent since the early 20th century. It's the result, scientists theorize, of stress from pollution and melting habitat.

42. A mysterious disease that killed off more than a third of American honeybees in 2007-08 may have been caused in part by a virus.
