Infanticide Intrigue in the Eclectus Parrot

in biology

The mysterious behaviour of female Eclectus parrots killing their sons immediately after they hatch has been unravelled by a team of researchers from the Australian National University. Such sex-specific infanticide occurs in some human societies (where baby girls are killed) but is rare in other species.

in biology, omics

Two groups of scientists now report that they have discovered how plants sense low oxygen levels to survive flooding – a finding that could lead eventually to the production of high-yielding, flood-tolerant crops, benefiting farmers, markets and consumers everywhere.

CK1 protein possible cancer therapeutic target

in medicine

Researchers from the NYU Cancer Institute, an NCI-designated cancer center at NYU Langone Medical Center, have identified a cell cycle-regulated mechanism behind the transformation of normal cells into cancerous cells. The study shows the significant role that protein networks can play in a cell leading to the development of cancer.

West Nile Virus Transmission - New Insights

in medicine, biology

West Nile virus can infect a wide range of animals, but only a few key species of bird "hosts" and mosquito "vectors" are important in transmission of the virus, according to an article published in Science.  West Nile virus spread across the United States in just a few years after its initial appearance in New York in 1999.  The virus is now well established throu
