On the origin of nematodes: Phylogenetic tree of world's most numerous
Scientists have published the largest nematode phylogenetic tree up until now. It contains over 1,200 species and is entirely based on the analysis of DNA sequence data. Many Choose More Aggressive Breast Cancer Surgery Despite Breast-spari
When women, not their surgeons, have control over the type of surgery they receive, they are more likely to choose a more aggressive surgery that removes the entire breast, even though survival rates are the same for surgery that removes only the tumor. The Hive and the Honeybee: Selections from the E. F. Phillips Beekeepi
This collection represents "one of the largest and most complete apiculture libraries in the world."Search and browse the full text of ten rare books, including "Mysteries of Bee-keeping Explained"(1853) and "New Observations on the Natural History of Bees"(1806). From the Albert R. Mann Library at Cornell University. Face Value: Hidden Smiles Influence Consumption And Judgment
In studies led by Piotr Winkielman, of the University of California, San Diego, people altered their consumption behaviors after exposure to subliminal facial expressions. Hidden smiles persuaded thirsty subjects to pour more and drink more of an unidentified beverage than did neutral expressions. Frowns had the opposite effect. Human Y Chromosome Stays Intact While Chimp Y Loses Genes
The human and the chimpanzee Y chromosomes went their separate ways approximately 6 million years ago. But ever since this evolutionary parting, these two chromosomes have experienced different fates. While the human Y has maintained its count of 27 genes and gene families, some of these same genes on the chimp Y have mutated and gradually become inactive. The authors speculate that one likely reason for such disparity is due to chimpanzee mating habits. Retina Adapts To Seek The Unexpected, Ignore The Commonplace
Researchers at Harvard University have found evidence that the retina actively seeks novel features in the visual environment, dynamically adjusting its processing in order to seek the unusual while ignoring the commonplace. The scientists report in this week's issue of the journal Nature on their finding that this principle of novelty-detection operates in many visual environments. New NASA Office Will Study Strange Cosmic Phenomena
NASA's Goddard Space Flight Center will house the agency's new Einstein Probes Office, created to study the universe's exotic phenomena: dark energy, black holes and cosmic microwave background radiation. New Targets For Treatment Of Invasive Breast Cancer Discovered
Scientists have shown for the first time that a tiny piece of RNA appears to play a major role in the development of invasive breast cancer and identified a gene that appears to inhibit invasive breast cancer. Antarctic Ozone Hole Is A Double Record Breaker
NASA and National Oceanic and Atmospheric Administration scientists report this year's ozone hole in the polar region of the Southern Hemisphere has broken records for area and depth. Discovering Distant Galaxies: HAWK-I Takes Off
Europe's flagship ground-based astronomical facility, the ESO VLT, has been equipped with a new 'eye'to study the Universe. Working in the near-infrared, the new instrument -- dubbed HAWK-I -- covers about 1/10th the area of the full moon in a single exposure. It is uniquely suited to the discovery and study of faint objects, such as distant galaxies or small stars and planets.
