Quantum effects writ large
02-15-2007 · EurekAlert!A team of physicists from Rice University, Rutgers University, and the Max Planck Institute for Chemical Physics of Solids in Dresden, Germany, reports this week in the journal Science the discovery of surprising quantum effects in a member of a broad class of materials that include high-temperature superconductors and quantum magnets. The effects were observed at a "quantum critical point," a tipping point at which the quantum properties of the material undergo a radical change.

- Study finds oysters can take heat and heavy metals, but not both
12-13-2006 · EurekAlert!
Could low-level heavy metal pollution be combining with warm water temperatures to fatally weaken sea life? A study examining the joint effects of cadmium and temperature on mitochondrial metabolism in oysters finds a combined effect that is potentially lethal and could be a significant contributor to recent oyster declines. The research has broad implications for cold-blooded marine organisms.

- It's never too late to get it back! Aging interrupted
04-01-2007 · EurekAlert!
Scientists have discovered that reducing calorie intake later in life can still induce many of the health and longevity benefits of life-long calorie reduction. Importantly, this also includes anti-cancer effects. They are using this knowledge to establish a novel screening technique to find drugs which mimic this longevity effect.

- Toll charges reduce travel time
09-25-2007 · EurekAlert!
A smart introduction of a variable toll charge, with different rates at different departure times, reduces traffic jams. Even small toll charges can exert a large effect on the total travel time, concludes Dutch researcher Dusica Joksimovic.

- Progress toward an alternative for EPO: Gas6 offers remedy where EPO fails today
01-31-2008 · EurekAlert!
Many patients with a chronic disease or cancer have to contend with anemia. At present, the hormone EPO is administered to a large number of these patients to alleviate the anemia. But unfortunately, treatment with EPO is not always effective. VIB scientists have been researching the role of the Gas6 protein. This substance has proven successful in the treatment of mice with anemia. In addition, Gas6 contributes to a reinforcement of EPO's effect.

- Study finds school environment can moderate student aggression
04-23-2007 · EurekAlert!
The culture of a school can dampen -- or exacerbate -- the violent or disruptive tendencies of aggressive young teens, new research indicates. A large-scale study from the University of Illinois found that while personal traits and peer interactions have the most direct effect on the aggressive behavior of middle school students, the school environment also influences student aggression.

- Study: Re-engineered Gleevec reduces heart risks
12-03-2007 · EurekAlert!
Using a new bottom-up approach for rational drug design, researchers at Rice University and the University of Texas M. D. Anderson Cancer Center have reengineered the powerful anticancer drug imatinib -- best known by its brand name Gleevec -- to more specifically target one type of cancer while potentially curbing a rare life-threatening cardiotoxic side effect. The re-design strategy employed in the study is broadly applicable to reducing side effects in other drugs.

11-15-2006 · EurekAlert!
A study published in the October journal of Clinical and Applied Thrombosis/Hemostasis shows Pycnogenol (pic-noj-en-all), an antioxidant plant extract from the bark of the French maritime pine tree reduced edema, a typical side effect of antihypertensive medications, by 36 percent in patients taking these medications.

- Modifying an anti-cancer drug makes it more specific
12-03-2007 · EurekAlert!
Imatinib is used to treat chronic myeloid leukemia and gastrointestinal stromal tumors because they are caused by related proteins. However, this lack of specificity means imatinib also affects normal bodily functions and it has been reported to have a toxic effect on the heart in some patients. Now, researchers have modified imatinib so it inhibits the protein behind GISTs but neither inhibits the protein behind CML nor has toxic effects on the mouse heart.

- Imaging quantum entanglement
09-21-2007 · EurekAlert!
An international team including scientists from the London Center for Nanotechnology today publishes findings in the journal Proceedings of the National Academy of Sciences demonstrating the dramatic effects of quantum mechanics in a simple magnet. The importance of the work lies in establishing how a conventional tool of material science -- neutron beams produced at particle accelerators and nuclear reactors -- can be used to produce images of the ghostly entangled states of the quantum world.
