Natural Compounds, Chemotherapeutic Drugs May Become Partners In Cancer Therapy Posted: 07 Sep 2009 08:00 AM PDT Research suggests that some natural food compounds, which previously have been studied for their ability to prevent cancer, may be able to play a more significant role in treating it -- working side-by-side with the conventional drugs that are now used in chemotherapy.

Chemotherapy For Breast Cancer Is Associated With Disruption Of Sleep-wake Rhythm In Women Posted: 07 Sep 2009 08:00 AM PDT A new study shows that the sleep-wake activity rhythms of breast cancer patients are impaired during the administration of chemotherapy. Results indicate that the first cycle of chemotherapy is associated with a temporary disruption of these rhythms, while repeated administration of chemotherapy results in progressively worse and more enduring impairments.

Cheat-Resistant 3D IPhone Game Relies On Score-Checking Replays Posted: 07 Sep 2009 08:00 AM PDT Aliens are stealing your beloved sheep and you've got to stop them. That's the premise for TowerMadness, a new 3D iPhone game that is one of the most cheat-resistant iPhone games available, according to its three developers, all with ties to the University of California, San Diego.

Targeted Investments In Climate Science Could Present Enormous Economic Savings Across The Globe Posted: 07 Sep 2009 08:00 AM PDT Targeted investments in climate science could lead to major benefits in reducing the costs of adapting to a changing climate, according to new research. The study shows that investments made now, can lead to as much as 10-20 percent improvement in climate predictions for the UK and Europe in the coming decades, and up to 20 percent across the rest of the globe.

Humans Causing Erosion Comparable To World’s Largest Rivers And Glaciers, Study Finds Posted: 07 Sep 2009 05:00 AM PDT A new study finds that large-scale farming projects can erode the Earth's surface at rates comparable to those of the world's largest rivers and glaciers. The research offers stark evidence of how humans are reshaping the planet. It also finds that -- contrary to previous scholarship -- rivers are as powerful as glaciers at eroding landscapes.

More Genetic Risk Factors For Alzheimer's Disease Found Posted: 07 Sep 2009 05:00 AM PDT An international team of scientists has identified two more genetic risk factors for Alzheimer's disease. The group completed the largest genome-wide association study ever involving patients with Alzheimer's disease. The study pooled DNA samples from more than 19,000 older European and US residents.

Promising New Target Emerges For Autoimmune Diseases Posted: 07 Sep 2009 05:00 AM PDT Scientists have uncovered an important way that aggressive immune cells normally are held in check so they don't attack the body's own cells. The findings open a new avenue of research for future therapies for autoimmune diseases, organ transplants and cancer. Regulatory T cells influence aggressive immune cells by regulating the chemical environment between cells, the scientists report in Nature Chemical Biology.

New Asthma Predictors Needed To Determine Future Risk In Certain Patients Posted: 07 Sep 2009 05:00 AM PDT Screening tests used to predict asthma activity in patients may have little tracking success when applied to people with persistent disease who are adhering to their health care regimens, physicians report.

Climate Change Influences The Size Of Marine Organisms: Big Advantage For The Small Posted: 07 Sep 2009 05:00 AM PDT The ice is melting, the sea level is rising and species are conquering new habitats. The warming of the world climate has many consequences. Researchers now report that climate change influences the size of aquatic organisms.

Access To Motorbikes Without Taking Prior Exam Increases Number Of Accidents, Study Finds Posted: 07 Sep 2009 05:00 AM PDT Pedestrians and motorcyclists continue to be those most vulnerable in traffic accidents. Researchers in Spain have demonstrated an increase in the number of injuries among users of lightweight motorcycles after a law was passed in 2004 allowing the riding of motorbikes with a class B licence (for cars). In contrast, the study, focusing on Barcelona, confirms that the risk of having an accident has remained unchanged.

That Late-night Snack: Worse Than You Think Posted: 07 Sep 2009 02:00 AM PDT Eat less, exercise more. Now there is new evidence to support adding another "must" to the weight-loss mantra: eat at the right time of day. A study has found that eating at irregular times -- the equivalent of the middle of the night for humans, when the body wants to sleep -- influences weight gain. This is the first causal evidence linking meal timing and increased weight gain.

Key Protein Controlling Brain Formation Identified Posted: 07 Sep 2009 02:00 AM PDT Researchers have identified a protein which plays a key role in the development of neurons, which could enhance our understanding of how the brain works, and how diseases such as Alzheimer's occur.

Satellites And Submarines Give The Skinny On Sea Ice Thickness Posted: 07 Sep 2009 02:00 AM PDT This summer, a group of scientists and students -- as well as a Canadian senator, a writer, and a filmmaker -- set out from Resolute Bay, Canada, on the icebreaker Louis S. St-Laurent. They were headed through the Northwest Passage, but instead of opening shipping lanes in the ice, they had gathered to open up new lines of thinking on Arctic science.

Racial Disparity Studied In Patients Undergoing Liver Transplantation For Hepatitis B Posted: 07 Sep 2009 02:00 AM PDT According to the Centers for Disease Control and Prevention, 1.5 to 2 million Americans are infected with the hepatitis B virus. Prior studies have shown there to be significant racial differences in access to and outcomes of liver transplantation. Recently, doctors from across the US conducted a multicenter retrospective-prospective study of the waitlist status and outcomes of liver transplant patients with HBV infection.
