Bumblebees copy one another when contending with unfamiliar flowers

Researchers have reported findings that offer a surprising new twist to our understanding of how bumblebees, a vital floral pollinator, select the flowers from which they collect nectar. When faced with unfamiliar plants, foraging bees do not choose flowers entirely alone but instead copy the choices of other bees. The new findings suggest that bees adjust their behavior when dealing with flowers...

Recreating 'Flowers for Algernon' with a happy ending

In a surprise twist that recalls the film classic "Flowers for Algernon," but adds a happy ending, UCLA scientists used statins, a popular class of cholesterol drugs, to reverse the attention deficits linked to the leading genetic cause of learning disabilities. The Nov. 8 issue of Current Biology reports the findings, which were studied in mice bred to develop the disease, called neurofibromato...

AIDS drug from sunflowers

Sunflowers can produce a substance which prevents the AIDS pathogen HIV from reproducing, at least in cell cultures. This is the result of research carried out by scientists at the University of Bonn in cooperation with the caesar research centre. For several years now the hopes for a completely new group of AIDS drugs have been pinned to what is known as 'DCQA'. However, the substance is only av...

Wild bees and the flowers they pollinate are disappearing together

The diversity of bees and of the flowers they pollinate, has declined significantly in Britain and the Netherlands over the last 25 years according to research led by the University of Leeds and published in Science this Friday (21 July 2006). The paper is the first evidence of a widespread decline in bee diversity. Concerns have been raised for years about the loss of pollination service...

Genetic snooze button governs timing of spring flowers

In the long, dark days of winter, gardeners are known to count the days until spring. Now, scientists have learned, some plants do exactly the same thing. Addressing scientists here today (Aug. 9) at a meeting of the American Society of Plant Biologists, University of Wisconsin-Madison researcher Richard Amasino described studies that have begun to peel back some of the mystery of how pla...

Sunflowers Could Hold the Key to New Class of AIDS Drugs

Scientists at the University of Bonn in Germany have come up with what could be a potential AIDS drug. They have found that a substance present in sunflowers prevents // the AIDS virus from replicating in cell cultures. It is not yet known if this would also apply to the actual disease. The substance called as 'DCQA' has been the sole hope of producing a new class of AIDS drugs. But thi...

Oleic-acid-rich Sunflowers Give Trans-fat Alternative - Study

Oil from genetically modified sunflowers has increased stability against oxidation, giving them a longer shelf life, as well as having// an improved health profile, suggests new research. However, while the news of another potential trans-fat replacement oil will be readily accepted in the US, public concerns over genetically modified food sources seem certain to present a barrier to...

April Showers Bring May Flowers – And Plenty of Pollen, To

With allergy season in full bloom, the American Academy of Otolaryngology – Head and Neck Surgery is offering a reminder of what you can do to cope with the pollen in the air, and how an ear, nose, and throat specialist can help. // This spring, pollen from blooming trees and plants will join other allergens in affecting over 45 million Americans, causing itching eyes, sneezing, nasal...

Male Wallflowers-Watch Your Heart

Latest research shows that timid and withdrawn men increase their chances of dying from heart attacks by up to fifty percent, as against their more gregarious peers . The scientists led by Jarett Berry and Philip Greenland of Northwestern University of Chicago, who published their findings in The Annals of Epidemiology, drew their conclusions from a study of 2100 middle-aged me...
