The Roots of Upright Walking

By Posted on 4.24.2008 8 Comments
Scientists have long been trying to figure out why early humans became bipedal, and one popular explanation has now been crossed off the list of possibilities. There was a popular notion that we started walking upright to free up our arms so we could carry objects, and babies—apes don't need to worry about this because their offspring can cling to them using their hands and feet. It's like a built-in Baby Bjorn. But now University of Manchester researchers say the baby-carrying theory doesn't hold, mainly because supporting an infant on your hip or in your arms is too tiring to have been a legitimate factor in the transition to bipedalism.

Turning an Ant Into a Berry

By Posted on 4.24.2008 8 Comments
Parasites are well known to have evolved an exceptional array of strategies for perpetuating themselves. A microscopic tropical nematode worm which lives in the gasters of ants in Panama is one of the more impressive. Researchers at the University of Arkansas have recently illuminated its method, which manages to make the ant appear to be a fruit so that it will be eaten by birds.

Genetic Testing: Cheaper, Easier

By Posted on 4.24.2008 6 Comments
Just as CD players, personal computers, and HDTVs were prohibitively expensive when they were first released, so too was the cost of sequencing the entire genome of an individual. In 2003 that feat was accomplished for the staggering amount of $437,000,000 after 13 years of work. Today, CD players are ubiquitous and cheap; HDTVs are steadily entering the realm of affordability; and so, too, has the cost of sequencing a genome fallen precipitously. It will still set you back $1,000,000 and two months of time, but that is a tremendous savings over just five years ago.
