Evolution may make men ignorant and gullible.
Gentlemen: ignorance is bliss and gullibility is the best policy. A new mathematical analysis suggests that evolution favours babies who don’t much resemble their fathers, and males who believe their partner when she says a child looks just like him.
Anonymous-looking newborns make for uncertain fathers. But they also allow men to father children through undetected adultery, Paola Bressan of the University of Padova calculates
Researchers have discovered the mechanism by which the genetic defect underlying cystic fibrosis (CF) leads to fatal bacterial colonization of the lungs. The new findings, published today in the early online edition of the Proceedings of the National Academy of Sciences, suggest that an aerosol treatment aimed at balancing pH in lung cells could be developed to stave off or delay such infections.
The most common inherited lethal disorder in Caucasians, CF stems from mutations in a gene that
Bacteria caught mating with mammalian cells.
Cross-species coupling is generally frowned upon. But in the liberal labs of California it is actively being encouraged. Bugs that are persuaded to get down and dirty with hamster cells are rewriting sex manuals in the act.
Like humans, bacteria mate using a timely protruding phallus. It suckers a nearby bacterium and drags it close enough to shoot in DNA – a process called conjugation.
Although bacteria have been persuad
Mount Vesuvius, the volcano most famous for blanketing the towns of Pompei and Herculaneum with lava and debris in 79 A.D., may be sitting atop a reservoir of magma that covers more than 400 square kilometers, a new study suggests. The finding, reported in the current issue of the journal Science by a group of Italian and French scientists, may lead to more accurate monitoring of the area surrounding the volcano.
Building on previous work that suggested the presence of a magma zone underne
Scientists have detected a molecule they’ve been looking for since the 1920s.
Scientists in Italy have discovered a new form of oxygen 1 . In addition to the two well-known forms – ozone and the oxygen molecules in air – there is a third, they say, in which oxygen atoms are grouped in fours.
The oxygen molecules that we breathe (denoted O 2 ) consist of two oxygen atoms. This, the most stable form of oxygen, makes up about one-fifth of air. Ozone is
One gene controls whether a persistent pest serves one or many queens.
A protein that spots smell controls the power structure of fire ant colonies, Michael Krieger and Kenneth Ross of the University of Georgia, Athens, have discovered 1 . One form of the protein leads to nests with several queens living in harmony. The other leaves only one ruler.
Fire ants social life is of more than academic interest. The species (Solenopsis invicta) has spread from
