Research identifies protein that signals flowering in squash plants

...short (and days are long), and typically flower in late spring or early summer. SD crops include rice and maize, and LD crops include wheat, barley, oats and peas. Day-neutral plants will flower under either long or short days. In addition to its fundamental importance in basic plant biology, understandin...

Old memory traces in brain may trigger chronic pain

...se. In Apkarian’s previous study, published in late 2006, he revealed that chronic back pain appears in a different part of the brain than the discomfort of burning your finger, for example. With a functional MRI, he found that chronic back pain shows up in the prefrontal cortex. By contrast, the acut...

Research team identifies new Alzheimer's gene

...nificant gene found to predispose an individual to late onset Alzheimer’s (LOAD) has been APOE4. In this latest study, researchers from seven organizations contributed to the genome-wide scan using Affymetrix microarray technology. The team screened the DNA from 1,400 individuals who had been clinically a...

During complementary reconnaissance surveys in late May, Elkan, WCS pilot Falk Grossman and Jamus Joseph, assistant director of the WCS Southern Sudan Country Program, did finally sight a group of three zebra moving with the white-eared kob migration in Boma National Park. The team also identified a k...

Potato wart eyed as risk to potato production

While many may be familiar with potato late blight, the plant disease responsible for widespread potato shortages, the lesser known potato wart has the potential to be as devastating to economies that depend on potato production, say plant pathologists with The American Phytopathological Socie...

NASA-funded robotic sub finds bottom of world's deepest sinkhole

The quest for an effective HIV vaccine presents new possibilities, challenges

...igh levels of virus--namely those in the early and late stages of infection--are most likely to infect their sexual partners. A preventive vaccine given before exposure to HIV might stifle the initial burst of virus, better control virus levels and potentially reduce that person’s ability to infect other ...

Study warns deep-sea mining may pose serious threat to fragile marine ecosystems

...rmed through undersea volcanic activity. Until the late 1970s, scientists had assumed that life required sunlight, but the discovery of these vent communities showed that life could exist on thermal and chemical energy. Since oceans have existed, more or less, since the beginning of Earth's history, these...

Hives ferment a yeasty brew, attract beetle pest

...rst seen infesting U.S. beehives in Florida in the late 1990s. The researchers tested the response of both the small hive beetles and honeybees to isopentyl acetate (IPA), the major chemical in the bee's alarm pheromones. The first tests showed that when worker bees become alarmed, they produce from 1,...
