- Sea Salt Worsens Coastal Air Pollution
Air pollution in the world's busiest ports and shipping regions may be markedly worse than previously suspected, according to a new study showing that industrial and shipping pollution is exacerbated when it combines with sunshine and salty sea air.
Mon, 14 Apr 2008 11:00:00 EDT - Stem Cells Offer Cartilage Repair Hope For Arthritis Sufferers
New research could offer hope that bone stem cells may be harnessed to repair the damaged cartilage that is one of the main symptoms of osteoarthritis. Scientists have successfully identified stem cells within articular cartilage of adults, which although it cannot become any cell in the body like full stem cells, has the ability to derive into chondrocytes - the cells that make up the body's cartilage -- in high enough numbers to make treatment a realistic possibility.
Mon, 14 Apr 2008 11:00:00 EDT - Fly Is At Home On A Crab, With New Evolutionary Neighbors
Scientists have rediscovered a fly living in the mouth of land crabs. One of the more bizarre choices of breeding substrates comes from Drosophila endobranchia. This species is one out of three known fruit flies that have found a home on (and inside) land-crabs. Although frequently mentioned in biology textbooks, the crab flies have somewhat surprisingly been neglected in active research since their description. The fly has actually not even been seen since its initial discovery in 1966.
Mon, 14 Apr 2008 11:00:00 EDT - The Good And Bad Side Of Anti-cancer Compounds
Two recent studies provide a potential mechanism by which investigational anti-cancer compounds known as HDAC inhibitors specifically damage cancer cells as well as clues about possible adverse effects of these compounds -- findings with important implications for their clinical use as cancer therapies.
Mon, 14 Apr 2008 11:00:00 EDT - Nervous System For Airplanes, Bridges And Other Structures Should Improve Safety
Technical structures may soon have their own nervous system. Developers and users expect this to bring greater safety, maintenance activities only when required, and a more efficient use of material and energy. Sophisticated systems of sensors, actuators and signal processing devices detect cracks, rust and other defects at an early stage in order to prevent damage – especially in critical places that are difficult to reach.

Boys benefit a great deal from having girls in the classroom. And there are benefits for both genders. A higher percentage of girls in a classroom lowers the amount of classroom disruption and fosters a better relationship between pupils and their teacher, a study of the data suggests. Teachers are less tired in classrooms with more girls, and pupils overall seem to be more satisfied when a high female-to-male ratio persists.
Mon, 14 Apr 2008 11:00:00 EDT - Unusual Earthquake Swarm Off Oregon Coast Puzzles Scientists
Scientists have recorded more than 600 earthquakes in the last 10 days off the central Oregon coast in an area not typically known for a high degree of seismic activity. This earthquake "swarm" is unique, according to marine geologists, because it is occurring within the middle of the Juan de Fuca plate -- away from the major, regional tectonic boundaries.
Mon, 14 Apr 2008 08:00:00 EDT - T-cell Multiplication Unexpectedly Delayed After Infection
In a surprising outcome that overturns the conventional wisdom on the body's immune response to infection, scientists have shown that T-cells do not begin proliferation until up to three days after infection. Lag may provide protection against a possible autoimmune reaction.

Even large amounts of manufactured nanoparticles, also known as Buckyballs, don't faze microscopic organisms that are charged with cleaning up the environment, according to new research.
Mon, 14 Apr 2008 08:00:00 EDT - Stem Cells And Cancer: Cancer Pathways That Also Control The Adult Stem Cell Population
Researchers in the United Kingdom are investigating a mechanism that normally drives adult stem cells to repair the intestine. They have found that if things go wrong and a crucial gene called Apc is lost or damaged, then this normal function of controlling the adult stem cell population breaks down and ultimately leads to a tumour.
Mon, 14 Apr 2008 08:00:00 EDT - More Safety For Cell Phone Batteries
Researchers have created a novel safer lithium-ion battery. It is based on a polymer electrolyte, which is -- unlike the liquid electrolyte in conventional lithium-ion batteries -- not inflammable. Lithium-ion batteries supply the power for cell phones and PDAs, and larger devices such as laptops, cordless screwdrivers and lawnmowers are becoming increasingly dependent on this power source.
Mon, 14 Apr 2008 08:00:00 EDT - Does The Internet Really Influence Suicidal Behavior?
People searching the Internet for information about suicide methods are most likely to come across sites that encourage suicide rather than sites offering help and support, finds a new study.
Mon, 14 Apr 2008 08:00:00 EDT - Supercomputers Simulating As Close As Possible To Reality
Supercomputers simulate products and manufacturing processes within minutes. In the Computer Aided Robust Design CAROD project, researchers are developing new methods and software that significantly improve the quality of the virtual components.
Mon, 14 Apr 2008 05:00:00 EDT - Developing Cancer Treatments Directed At Critical Developmental Pathway
Researchers discovered that the Notch signaling pathway, which determines the development of many cell types, and is also implicated in some cancers, is not universally essential for the maintenance of stem cells. This indicates that inhibitors of Notch may not affect bone marrow stem cells.
Mon, 14 Apr 2008 05:00:00 EDT - Extracts From Reishi Mushroom And Green Tea Shows Synergistic Effect To Slow Sarcoma
Reishi mushroom and green tea scientific studies have found that combining the active ingredients in the mushroom and the tea creates synergetic effects that inhibited the growth of tumors and delayed the time of death in mice with sarcomas.
