New Hearing Mechanism Discovered:
MIT researchers have discovered a hearing mechanism that fundamentally changes the current understanding of inner ear function. This new mechanism could help explain the ear's remarkable ability to sense and discriminate sounds. Its discovery could eventually lead to improved systems for restoring hearing.
People Are Programmed To Love Chocolate, Study Finds:
For the first time, scientists have linked the all-too-human preference for a food -- chocolate -- to a specific, chemical signature that may be programmed into the metabolic system and is detectable by laboratory tests. The signature reads 'chocolate lover' in some people and indifference to the popular sweet in others, the researchers say.
Green Algae: The Nexus Of Plant-Animal Ancestry:
Genes of a tiny, single-celled green alga called Chlamydomonas reinhardtii may contain scores more data about the common ancestry of plants and animals than the richest paleontological dig. This work is described in an article in Science.
Frozen Sperm Worked For White Rhino:
Scientists from the Leibniz Institute for Zoo and Wildlife Research in Berlin successfully inseminated a rhino with formerly frozen sperm. This world-first artificial insemination of a white rhino with frozen rhino sperm took place in Budapest Zoo.
Spread Of Endogenous Retrovirus K Is Similar In The DNA Of Humans And Rhesus Monkeys:
According to paleontologic and molecular studies, the chimpanzee (Pan troglodytes) is the closer relative to the humans (Homo sapiens) and that both lineages had a common ancestor at 5 to 7 million years ago.
Benefits Of 80 Million Years Without Sex:
Scientists have discovered how a microscopic organism has benefited from nearly 80 million years without sex. Bdelloid rotifers are asexual organisms, meaning that they reproduce without males. Without sex, these animals lack many of the ways in which sexual animals adapt over generations to survive in their natural environment.
