It is now generally accepted that the bowhead whale is the longest lived mammal on the planet, with a lifespan of over 200 years. But that it can sing with “more than one voice” and that it changes its repertoire from year to year is news. This behavior is unique among baleen whales and is [...]

An analysis of rare genetic disorders in which children lack some genes from one parent suggests that maternal and paternal genes engage in a subtle tug-of-war well into childhood, and possibly as late as the onset of puberty.

In their most recent experiments with Geobacter, the sediment-loving microbe whose hairlike filaments help it to produce electric current from mud and wastewater, scientists supervised the evolution of a new strain that dramatically increases power output per cell and overall bulk power. It also works with a thinner biofilm than earlier strains, cutting the time [...]

A new study shows that the stress signaling protein, AMPK, facilitates infection by harmful bacteria. AMPK is chronically elevated in some types of diseases, suggesting that this protein may cause patients with these diseases to be more susceptible to noxious infection.
Ever since graphene was discovered in 2004, this one-atom thick, super strong, carbon-based electrical conductor has been billed as a “wonder material” that some physicists think could one day replace silicon in computer chips. But graphene, which consists of carbon atoms arranged in a honeycomb lattice, has a major drawback when it comes to applications [...]

Researchers have identified factors that may increase overweight adolescents’ risk of engaging in extreme weight control behaviors such as self-induced vomiting, the use of diet pills, laxatives and diuretics, as well as binge eating.
Using different state-of-the-art techniques on ESO’s Very Large Telescope, two independent teams of astronomers have obtained the sharpest ever views of the supergiant star Betelgeuse. They show that the star has a vast plume of gas almost as large as our Solar System and a gigantic bubble boiling on its surface. These discoveries provide important [...]

With a novel therapeutic delivery system, scientists have successfully targeted a protein that is over-expressed in ovarian cancer cells. Using the EphA2 protein as a molecular homing mechanism, chemotherapy was delivered in a highly selective manner in preclinical models of ovarian cancer.

Results of a long-awaited study of 3,070 American adults show that treatment with either of the two standard antiviral drug therapies is safe, and offers the best way for people infected with hepatitis C to prevent liver scarring, organ failure and death.
