Major flooding risk could span decades after Chinese earthquake
Up to 20 million people, thousands of whom are already displaced from their homes following the devastating Chinese earthquake, are at increased risk from flooding and major power shortages in the massive Sichuan Basin over the next few decades and possibly centuries.

Low-birth-weight children should have their blood pressure checked, researchers find
Blood pressure in low-birth-weight children younger than 3 years of age not only can be measured but should be, researchers at UT Southwestern Medical Center have found.

Gene enhancer in evolution of human opposable thumb
Scientists have discovered a gene enhancer, known as HACNS1, that may have contributed to the evolution of the uniquely opposable human thumb, and possibly also modifications in the ankle or foot that allow humans to walk on two legs.

TAU Researchers Create New Stem Cell Screening Tool
Stem cell research is the next great leap in medicine. In the future, new tissue grown in a laboratory could replace a failing heart, or new cells take the place of damaged cells in the brain.

University of Virginia Study Reveals Promising Method for Reducing MRSA Infections in Hospital Intensive Care Units
Doctors at the University of Virginia Health System have significantly reduced MRSA infections among surgical intensive care patients by using antibiotic cycling, a method of rotating drugs at regular intervals.

Bisphenol A linked to metabolic syndrome in human tissue
New research from the University of Cincinnati (UC) implicates the primary chemical used to produce hard plastics-bisphenol A (BPA)-as a risk factor for metabolic syndrome and its consequences.

Study: Delaying evolution of drug resistance in malaria parasite possible
There's no magic bullet for wiping out malaria, but a new study offers strong support for a method that effectively delays the evolution of drug resistance in malaria parasites, a University of Florida researcher says.

African-Americans have unique lung cancer risks from chronic obstructive pulmonary disease
Scientists at the M.D. Anderson Cancer Center have developed a risk prediction assessment for lung cancer specifically for African Americans that suggests a greater risk from chronic obstructive pulmonary disease (COPD).

NIST studies how new helium ion microscope measures up
Just as test pilots push planes to explore their limits, researchers at the National Institute of Standards and Technology (NIST) are probing the newest microscope technology to further improve measurement accuracy at the nanoscale.

Thumbs up -- a tiny ancestral remnant lends developmental edge to humans
Subtle genetic changes that confer an evolutionary advantage upon a species, such as the dexterity characteristic of the human hand, while difficult to detect and even harder to reproduce in a model system, have nevertheless generated keen interest amongst evolutionary biologists.

Atomic structure of the mammalian 'fatty acid factory' determined
Mammalian fatty acid synthase is one of the most complex molecular synthetic machines in human cells. It is also a promising target for the development of anti-cancer and anti-obesity drugs and the treatment of metabolic disorders.

Rhode Island Hospital study finds link between obesity, type 2 diabetes and neurodegeneration
New research from Rhode Island Hospital found that obesity and Type 2 Diabetes Mellitus (T2DM) can contribute to mild neurodegeneration with features common with Alzheimer's disease (AD) - the first study to show that obesity can cause neurodegeneration.

Study firmly shows no connection between measles, mumps, rubella (MMR) vaccine and autism
In a case-control study, the presence of measles virus RNA was no more likely in children with autism and GI disturbances than in children with only GI disturbances.

ISU researchers help map first plant-parasitic nematode genome sequence
There are numerous plant-parasitic nematodes in the world, but only a handful are responsible for the largest part of an estimated $157 billion in agricultural damage globally every year. Nematodes are small worms that burrow into plant roots and feed off living cells.
