19. For small- and large-stature adults, automobile airbags may do more harm than good, new research indicates. A detailed look at crash data spanning 11 years for more than 65,000 front-seat passengers found that while airbags are "modestly" protective for people of medium stature (5-foot-3 to 5-foot-11), they appear to increase the risk of injury to people smaller than 4-foot-11 and taller than 6-foot-3.

20. U.S. military troops rarely consume all the components in MRE provisions, particularly when they are preparing for missions where reducing the amount of weight and bulk in their packs is essential. Instead, they "field strip" the rations, choosing their favorite items and tossing out the rest.

23. A race of 36 million-year-old, extinct giant penguins (over 5 feet tall) marched to equatorial South America during a time when the world was much warmer than it is now. Remains of the penguins found on the southern coast of Peru challenge previous conceptions about penguin evolution and expansion.

24. Icebergs hold trapped terrestrial material, which may be released far out at sea as they melt. This process produces a "halo effect" with significantly increased nutrients, chlorophyll and krill out to a radius of more than two miles. Scientists also have begun to suspect that icebergs may play a role in global climate regulation by removing carbon from the atmosphere.

25. Fish use the threat of punishment to maintain stability in their social order. Small goby fish at Lizard Island on Australia's Great Barrier Reef use the threat of expulsion from the school as a powerful deterrent to keep subordinate fish from challenging those more dominant.

26. Ape-men ancestors began walking on two legs 6 million years ago because it used far less energy than clambering on all fours.
* * * * *
27. Some office printers emit a dangerous amount of toner in the air, possibly causing health concerns ranging from respiratory irritation to cardiovascular problems. Some of these floating microscopic particles may be carcinogens.

46. About two-thirds of students play video and computer games - 82 percent of male students and 59 percent of female students. Only about one quarter said they play games often with someone of the opposite sex.

49. The parasitic jewel wasp uses a venom injected directly into a cockroach's brain to inhibit its victim's free will and its motivation to walk. Unble to fight back, the "zombie" cockroach can be pulled into the wasp's underground lair, where an egg is laid in its abdomen. The larva later hatches and eats the still living but incapacitated cockroach from the inside out.
