Well-traveled Wasps Provide Hope For Vanishing Species
- ScienceDaily
- 10/1/11 07:05
They may only be 1.5mm in size, but the tiny wasps that pollinate fig trees can travel over 160km in less than 48 hours, according to new research. The fig wasps are transporting pollen ten times further than previously recorded for any insect. The fig wasps travel these distances in search of trees to lay their eggs, which offers hope that trees pollinated by similar creatures have a good chance...

Liver stiffness measurements identify patients with rapid or slow fibrosis
- ScienceDaily
- 10/1/11 07:05
A recent study finds that repeated liver stiffness measurements in the first year following liver transplant could discriminate between slow and rapid "fibrosers." Determining those at risk for a recurrence of hepatitis C virus allows for early-stage administration of therapies that could prevent LT or graft...
Single atom controls motility required for bacterial infection
- ScienceDaily
- 10/1/11 07:05
Researchers have discovered that a single atom -- a calcium, in fact -- can control how bacteria walk. The finding identifies a key step in the process by which bacteria infect their hosts, and could one day lead to new drug targets to prevent infection.
Brain activity levels affect self-perception: 'Rose-colored glasses' correlate with less frontal lobe use
- ScienceDaily
- 10/1/11 07:05
The less you use your brain's frontal lobes, the more you see yourself through rose-colored glasses, researchers have found.
Nanoscience goes 'big': Discovery could lead to enhanced electronics
- ScienceDaily
- 10/1/11 07:05
Nanoscience has the potential to play an enormous role in enhancing a range of products, including sensors, photovoltaics and consumer electronics. Scientists in this field have created a multitude of nano scale materials, such as metal nanocrystals, carbon nanotubes and semiconducting...
New method of measuring ocean carbon dioxide uptake could lead to climate change 'early warning system'
- ScienceDaily
- 10/1/11 07:05
Scientists have developed a new method of measuring the absorption of carbon dioxide by the oceans and mapped for the first time carbon dioxide uptake for the entire North Atlantic.
Melting tundra creating vast river of waste into Arctic Ocean
- ScienceDaily
- 10/1/11 06:00
The increase in temperature in the Arctic has already caused the sea-ice there to melt. According to new research from Sweden, if the Arctic tundra also melts, vast amounts of organic material will be carried by the rivers straight into the Arctic Ocean, resulting in additional emissions of carbon...
Neuroimaging may shed light on how Alzheimer's disease develops
- ScienceDaily
- 10/1/11 06:00
Current Alzheimer's disease research indicates that accumulation of amyloid-beta (AB) protein plaques in the brain is central to the development of AD. While previously presence of these plaques could only be confirmed at autopsy. Positron emission tomography provides researchers with an opportunity to test the amyloid hypothesis as it occurs in living patients. A new study summarizes the results...
New spider species is largest of its type in Middle East
- ScienceDaily
- 10/1/11 06:00
A new and previously unknown species of spider has been discovered in the dune of the Sands of Samar in the southern Arava region of Israel. Unfortunately, however, its habitat is endangered.
New ways to pressure HIV
- ScienceDaily
- 10/1/11 06:00
Two new studies show that protein bits produced by unusual "reading" of the HIV genome can induce immune responses. The information provided by these findings may prove useful during future HIV vaccine design efforts.

Molecule repairs alcohol metabolism enzyme
- ScienceDaily
- 10/1/10 06:00
About 1 billion people worldwide carry a genetic mutation that produces an inactive form of ALDH2, an important alcohol metabolism enzyme. When individuals with the ALDH2 mutation drink alcohol, the toxic compound acetaldehyde accumulates in the body. The inactive form of ALDH2 is linked to increased risk for cancer. Researchers found that an experimental compound restores the structure and...
