Social Skills in Infants?

Babies as young as six months develop “social judging skills before they [can] talk,” say researchers at Yale University, U.S.A. Babies aged six months to ten months watched a large-eyed toy try to climb hills, while other toys either helped it or pushed it backward. The children were then “presented with the toys to see which they would play with,” explains the Houston Chronicle.

Doomsday Clock Advances

Doomsday, Clock Advances
The doomsday clock, conceived by the Bulletin of Atomic Scientists (BAS) to illustrate how close mankind is to nuclear disaster, has been advanced two minutes, to read five minutes before midnight—the “figurative end of civilization.” The clock has only been reset 18 times in its 60-year history.

Prescription for Danger

Prescription for Danger, danger drugs, health drugs
“Medicines claimed more lives in Germany last year than traffic accidents did,” reported the newspaper Stuttgarter Nachrichten. Reportedly, some 25,000 people died in 1998 from wrongly prescribed drugs. This is three times as many as were killed in traffic accidents during the same period. Self-medication is said to play only a secondary role. The main problem seems to be a lack of information and training among doctors about the medicines and their effects. Pharmacologist Ingolf Cascorbi said that according to one estimate, “in Germany each year, 10,000 deaths and 250,000 cases of persons suffering from serious side effects could be avoided if research and training were optimized,” states the report.

An Explosion of Technology

In Albania it is not unusual to see an older person riding a donkey while talking on a cell phone. In India a beggar might pause in his solicitations to make or take a call on his phone. Yes, from cell phones to computers to television, technology has found its way into every corner of the world—even crossing the divide between rich and poor—and has become a part of life for many.

The pervasiveness of technology is perhaps most apparent in the proliferation of cell phones, many of which are no longer just phones. Advanced models enable users to access the Internet, send and receive e-mail and text messages, watch TV, listen to music, take photos, navigate by the Global Positioning System (GPS), and—oh, yes—phone someone!

Studying The Squid’s Beak

The beak of the squid baffles scientists. They wonder: ‘How can something that is so hard be attached to a body that has no bones? Should not the combination of materials cause abrasion and hurt the squid?’

The tip of the squid’s beak is hard, whereas the base of the beak is soft. The composition of the beak—which is made up of chitin, water, and protein—changes in density so gradually from soft to hard that the squid can use its beak without causing any harmful abrasion.

Glass spells danger for birds

Glass spells danger for birds, birds crash, birds crash glass

When windows are clean and clear, birds often see only what is on the other side, which may include greenery and sky. As a result, unsuspecting birds sometimes fly straight into the glass at full speed. Also, they may see decorative plants inside glass lobbies or homes and try to land on them.

Coated reflective glass can also be a problem. Under certain conditions, birds may see, not the glass, but a reflection of the surrounding area or sky and, here again, come to grief. Birds have even been killed by glass at visitors’ centers and on observation towers at bird sanctuaries and wildlife refuges! Ornithologist and biology professor Dr. Daniel Klem, Jr., believes that more birds are killed by flying into windows than by any other cause related to human activity, except perhaps habitat destruction.
