Honeydew Honeys Are Better Antioxidants Than Nectar Honeys
A study of 36 Spanish honeys from different floral origins revealed that honeys generated by bees feeding on honeydew have greater antioxidant properties than those produced by bees feeding on nectar. The study is published in this month's edition of the Journal of the Science of Food and Agriculture. Wisconsin Scientists Find Portal To Show Animals Evolve
Just as flashy plumage or imposing antlers work to an animal's reproductive advantage, so, too, do the colored spots that decorate the wings of a particular male fruit fly. To a team of Wisconsin scientists, however, the origin of these decorative spots has proven to be a critical portal to unraveling a long-standing genetic mystery: What is it, exactly, that governs the development and evolution of form? To Avoid Soccer Head Injuries, Soft Protective Headgear Is Only Effect
From small scrapes to hospital emergencies, playing soccer can be painful, and even dangerous. To avoid head injuries and concussions the only effective solution is wearing a soft protective headgear, as shown by Dr. Scott Delaney, research director of Emergency Medicine at the MUHC, in a new study published in the July issue of the British Journal of Sports Medicine. Discovery Offers Promising Lead In Prostate Cancer Diagnosis
Researchers led by Dr. Shiv Srivastava from the Center for Prostate Disease Research (CPDR), Uniformed Services University of the Health Sciences (USU), report the groundbreaking discovery of the ETS-Related Gene (ERG) as one of the frequent proto-oncogene overexpressions in prostate cancer cells. This discovery provides a very promising addition to a select group of genes, whose expression is frequently altered in prostate cancer cells and could provide novel molecular targets for diagnosis, prognosis or therapy of prostate cancer in the future. Proteins May Predict Lung Transplant Rejection
Researchers have identified three proteins that appear to be highly predictive of chronic lung rejection up to 20 months before the rejection occurred. Lung transplants are a common therapy for many end-stage lung diseases such as chronic obstructive pulmonary disease, cystic fibrosis and pulmonary hypertension. If doctors can predict which patients are beginning to reject the transplanted organ, they could try to head it off. Future Career Path Of Gifted Youth Can Be Predicted By Age 13 By SAT
The future career path and creative direction of gifted youth can be predicted well by their performance on the SAT at age 13, a new study from Vanderbilt University finds. The study offers insights into how best to identify the nation's most talented youth. Overall, the creative potential of the participants was extraordinary. The findings contradict recent reports that the SAT has no predictive value. Gear Gallery: Tank-Like Point-and-Shoot, Tablet PC for Students and Mo
Browse this week's Wired News gadget reviews for a camera that's nearly as tough as nails, a tablet PC that's great for students, and more of the latest tech. In-group Altruism And Hostility Toward Outsiders Evolved Together
Altruistic and warlike aspects of human nature may have a common origin. Altruism--benefiting fellow group members at a cost to oneself--and parochialism--hostility toward individuals not of one's own ethnic, racial, or other group--are common to human nature, but we don't immediately think of them as working together hand in hand. In fact the unexpected combination of these two behaviors may have enabled the survival of each trait according to new research. Voices From the Wall: Personal Stories About the Fall of the Berlin Wa
This site from 2006 celebrates the 16th anniversary of the reunification of Germany (October 3, 1990) and how the Berlin Wall came down starting on November 9, 1989. Features a timeline with video clips about the Berlin Wall, personal accounts, and material about how the wall has been "dismantled, destroyed, and commemorated."Includes links to related sites. From the German Embassy, Washington, D.C. Rockefeller Scientists Show That MicroRNAs Play An Essential Role In T
The beauty of fruit flies as a scientific model system is that they are easy to manipulate and they give results fast. New research from Ulrike Gaul, Ph.D., at Rockefeller University, takes advantage of these characteristics to show that microRNAs are powerful regulators of fundamental processes including cell survival and nerve and muscle development. Certain microRNAs are conserved between flies and humans, so that these findings may shed light on how different human genes are controlled.
