Tomato stands firm in face of fungus

Scientists at the University of Amsterdam have discovered how to keep one's tomatoes from wilting -- the answer lies at the molecular level. The story of how the plant beat the pathogen, and what it means for combating other plant diseases, is published May 9 in the open-access journal PLoS Pathogens.

TU Delft demonstrates for the first time how light squeezes through small holes

How does light pass through a tiny hole? For the first time, Dr. Aurele Adam and Professor Paul Planken of Delft University of Technology have succeeded in mapping this process properly. Their research also promises a significant improvement in Terahertz microscopy in the long term, a potentially interesting new imaging technique, and Terahertz microspectroscopy, a technique for identifying tiny...

Warming up for magnetic resonance imaging

A new method of magnetic resonance imaging, much faster, more selective -- able to distinguish even among different target molecular species -- and many thousands of times more sensitive, has been developed by researchers at the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at Berkeley. The new technique has the capacity to choose among targets by...

What's bugging locusts?

Since ancient times, locust plagues have been viewed as one of the most spectacular events in nature. In seemingly spontaneous fashion, as many as 10 billion critters can suddenly swarm the air and carpet the ground, blazing destructive paths that bring starvation and economic ruin.What makes them do it?In a word, cannibalism.

When statins aren't enough: New trial drug points to better management of coronary heart disease

Despite widespread use of cholesterol-lowering drugs, a significant number of cardiac patients continue to suffer heart attacks and stroke. Researchers theorize that high levels of an enzyme found in coronary plaques may be to blame, by making plaques more likely to rupture and block blood flow. The drug darapladib may offer a way to fight that risk, according to new research led by the University...

Young people are intentionally taking drink and drugs for better sex

Teenagers and young adults across Europe drink and take drugs as part of deliberate sexual strategies. Findings published today in BioMed Central's open access journal, BMC Public Health, reveal that a third of 16-35 year old males and a quarter of females surveyed are drinking alcohol to increase their chances of sex, while cocaine, ecstasy and cannabis are intentionally used to enhance sexual...

System uses sound to find whales, avoid ship strikes (AP)

AP - A spotter bangs three times on the boat's cabin roof, signaling the captain to cut the throttle — now. In the foggy gray of Cape Cod Bay, the reason for the abrupt stop soon becomes apparent: The research vessel is surrounded by rare North Atlantic right whales, their glossy black heads bobbing just above the surface as they feed on plankton...

Researchers find neuroblastoma genes (Reuters)

Reuters - An international team of researchers said they have pinpointed three variants of the genetic code that appear to set the stage for aggressive neuroblastoma, the deadliest solid tumor in early childhood.

Broadband service over power lines in Texas to shut down

(AP) -- Goodbye, broadband over power lines. We hardly knew you. Once touted as a possible third option for home broadband that could compete with phone and cable companies, the idea of providing Internet service over power lines now looks like it has died in infancy.

EU delays ruling on GM products

The European Commission on Wednesday ordered more tests on whether several genetically modified products should be allowed in Europe, putting back a decision on whether to give approval.
