Ecologist Brings Century-old Eggs To Life To Study Evolution Posted: 19 Jul 2009 02:00 PM PDT Suspending a life in time is a theme that normally finds itself in the pages of science fiction, but now such ideas have become a reality in the annals of science.

Chemicals Found In Fruit And Vegetables Offer Dementia Hope Posted: 19 Jul 2009 02:00 PM PDT A group of chemicals found in many fruits and vegetables, as well as tea, cocoa and red wine, could protect the brain from Alzheimer's disease, a dementia expert reports.

Toxin Detection As Close As An Inkjet Printer Posted: 19 Jul 2009 02:00 PM PDT A method for printing a toxin-detecting biosensor on paper has been developed. The process involves formulating an ink like the one found in computer printer cartridges but with special additives to make the ink biocompatible.

Increase In Thyroid Cancer Not Explained By Screening Alone Posted: 19 Jul 2009 02:00 PM PDT Studies have reported an increasing incidence of thyroid cancer since 1980. One possible explanation for this trend is increased detection through more widespread and aggressive use of screening tests. Researchers found incidence rates increased for all sizes of tumors, suggesting that screening is not the only explanation for the rise.

Single Molecules As Electric Conductors Posted: 19 Jul 2009 02:00 PM PDT Researchers report an important advance in the understanding of electrical conduction through single molecules.

The Fancier The Cortex, The Smarter The Brain? Posted: 19 Jul 2009 02:00 PM PDT Why are some people smarter than others? A new article describes how certain aspects of brain structure and function help determine how easily we learn new things, and how learning capacity contributes to individual differences in intelligence.

Why Winning Athletes Are Getting Bigger Posted: 19 Jul 2009 08:00 AM PDT A new theory by engineers has showed that not only have Olympic swimmers and sprinters gotten bigger and faster over the past 100 years, but they have grown at a much faster rate than the normal population.

Stealthy Gene Network Makes Brain Tumors Flourish Posted: 19 Jul 2009 08:00 AM PDT The brain tumor afflicting Sen. Edward Kennedy -- a glioblastoma -- is the most aggressive form of brain cancer. But scientists have discovered the tumor's vulnerability. They have identified a network of genes that create the perfect environment to allow the tumor to mushroom to the size of an apple in a just a few months. Researchers also identified a new gene whose level in the tumor predicts how long a glioblastoma patient will survive. The discoveries offer new targets for therapies.

King Crabs Go Deep To Avoid Hot Water Posted: 19 Jul 2009 08:00 AM PDT Researchers have drawn together 200 years' worth of oceanographic knowledge to investigate the distribution of a notorious deep-sea giant - the king crab. The results reveal temperature as a driving force behind the divergence of a major seafloor predator; globally, and over tens of millions of years of Earth's history.

Case For Preventive Prostate Cancer Treatment Bolstered Posted: 19 Jul 2009 08:00 AM PDT For the last six years, doctors have faced a dilemma about whether to treat men at risk of prostate cancer with the drug finasteride. Now new research appears to show that the drug did not cause those more aggressive forms of prostate cancer but simply made them easier to diagnose. The findings suggest that doctors can be less cautious in use of finasteride.

Marine Microorganisms: Surviving Mass Extinction By Leading A Double Life Posted: 19 Jul 2009 08:00 AM PDT Drifting across the world's oceans are a group of unicellular marine microorganisms that are not only a crucial source of food for other marine life -- but their fossils, which are found in abundance, provide scientists with an extraordinary record of climatic change and other major events in the history of the Earth.

A Bridge Too Far? Stark Warning From History Over Plans For 'Inhabited' London Bridge Posted: 19 Jul 2009 08:00 AM PDT On July 11, public celebrations will mark the 800th anniversary of the completion of London Bridge. Now, a new study has uncovered a tale of corruption, mismanagement, financial crisis and a property crash that resulted in the downfall of the Old London Bridge -- the capital's last 'living bridge'.

Learning Is Both Social And Computational, Supported By Neural Systems Linking People Posted: 19 Jul 2009 02:00 AM PDT Education is on the cusp of a transformation because of recent scientific findings in neuroscience, psychology, and machine learning that are converging to create foundations for a new science of learning.

Researchers Uncover Genetic Variants Linked To Blood Pressure In African-Americans Posted: 19 Jul 2009 02:00 AM PDT Researchers have discovered five genetic variants related to blood pressure in African-Americans -- findings that may provide new clues to treating and preventing hypertension. The effort marks the first time that a relatively new research approach, called a genome-wide association study, has focused on blood pressure and hypertension in an African-American population.

Moles And Melanoma: Genetic Links To Skin Cancer Found Posted: 19 Jul 2009 02:00 AM PDT Research shows the genetic connection between moles and melanoma -- and why the more moles a person has, the more susceptible they are to the disease. Researchers found a clear link between some genes on chromosomes 9 and 22 and increased risk of melanoma.

Genetic Factors That Hold Promise For Treatment Of Vascular Diseases Posted: 19 Jul 2009 02:00 AM PDT Researchers have discovered a key switch that makes stem cells turn into the type of muscle cells that reside in the wall of blood vessels. The same switch might be used in the future to limit growth of vascular muscle cells that cause narrowing of arteries leading to heart attacks and strokes, limit formation of blood vessels that feed cancers or make new blood vessels for organs that are not getting enough blood flow.

Mathematics Taking Guesswork Out Of Plastic Surgery Tissue Transfer Posted: 19 Jul 2009 02:00 AM PDT Plastic surgeons are turning to mathematics to take the guesswork out of efforts to ensure that live tissue segments that are selected to restore damaged body parts will have enough blood and oxygen to survive the surgical transfer. Mathematicians have shown that they can use differential equations to determine which tissue segments selected for transfer from one part of the body to another location on the same body will receive the level of oxygen required to sustain the tissue.

Popular Culture May Depict Car Surfing As Cool -- Journal Article Uncovers The Truth About This Potentially Deadly Activity Posted: 19 Jul 2009 02:00 AM PDT Why do people engage in stupid and potentially deadly activities, and why do teens in particular have a propensity for this behavior? An intriguing article answers these questions in the context of the reckless "sport" known as car surfing. The article not only analyzes the neurosurgical injuries associated with car surfing, but delves into the cultural and regional trends behind this dangerous recreational activity.
