Obese youth have significantly higher risk of gallstones Posted: 24 Aug 2012 05:57 PM PDT Children who are overweight or obese face an increased risk for gallstones, according to a new study.

Research shows children at risk from rural water supplies Posted: 24 Aug 2012 05:57 PM PDT Children drinking from around half the UK's private water supplies are almost five times more likely to pick up stomach infections – according to new research.

Ancestral link places Mexican-Americans at greater risk for metabolic disease Posted: 24 Aug 2012 02:09 PM PDT Mexican-Americans with an ancestral link to Amerindian tribes were found to have higher insulin resistance levels, which is an indication of several chronic conditions such as Type 2 diabetes, according to new research.

Good diet, proper exercise help protect astronauts’ bones Posted: 24 Aug 2012 10:19 AM PDT Eating right and exercising hard in space helps protect International Space Station astronauts' bones, a finding that may help solve one of the key problems facing future explorers heading beyond low Earth orbit.

New non-invasive method for diagnosing epilepsy Posted: 24 Aug 2012 10:03 AM PDT Biomedical engineers have outlined how a new type of non-invasive brain scan taken immediately after a seizure gives additional insight into possible causes and treatments for epilepsy patients. The new findings could specifically benefit millions of people who are unable to control their epilepsy with medication.

Boston subway system to be used to test new sensors for biological agents Posted: 24 Aug 2012 10:02 AM PDT The Department of Homeland Security's Science and Technology Directorate has scheduled a series of tests in the Boston subways to measure the real-world performance of new sensors recently developed to detect biological agents within minutes.

New strain of hand, foot and mouth virus worries parents, pediatricians Posted: 24 Aug 2012 08:14 AM PDT Your child goes to bed in perfect health. The next morning she wakes up with high fever, malaise and bright red blisters erupting all over her body. Dermatologists say the disturbing scenario has become quite common in the last few months, sending scared parents to their pediatrician's office or straight to the emergency room.

Most mutations come from dad: New insights into age, height and sex reshape views of human evolution Posted: 24 Aug 2012 07:30 AM PDT Humans inherit more than three times as many mutations from their fathers as from their mothers, and mutation rates increase with the father's age but not the mother's, researchers have found in the largest study of human genetic mutations to date.

Survival statistics show hard fight when malignant brain tumors appear at multiple sites Posted: 24 Aug 2012 07:29 AM PDT When aggressive, malignant tumors appear in more than one location in the brain, patient survival tends to be significantly shorter than when the disease starts as a single tumor, even though patients in both groups undergo virtually identical treatments, according to new research.

Newly discovered genetic markers could signal colon cancer development Posted: 24 Aug 2012 06:35 AM PDT Researchers have discovered how some proteins may cause the development of some forms of colon cancers.

Modeling metastasis Posted: 24 Aug 2012 06:34 AM PDT A technique used by animators helps scientists model how cancer cells enter the bloodstream.

Medical researchers identify PHF20, a regulator of gene P53 Posted: 24 Aug 2012 05:25 AM PDT Researchers have identified PHF20, a novel transcriptional factor, and clarified its role in maintaining the stability and transcription of p53, a gene that allows for both normal cell growth and tumor suppression. PHF20, the researchers found, plays a previously unknown and unique role in regulating p53.

Women with Alzheimer’s deteriorate faster than men Posted: 24 Aug 2012 05:25 AM PDT Women with Alzheimer's show worse mental deterioration than men with the disease, even when at the same stage of the condition, according to new research.

New insights to the function of molecular chaperones Posted: 24 Aug 2012 05:25 AM PDT Molecular biologists have gained new insights into the function of so-called molecular chaperones in protein synthesis. Scientists were able to demonstrate how a molecular chaperone in bacterial cells can influence the formation of the three-dimensional structure of new proteins.

Cup of herbal tea could help fight breast cancer Posted: 24 Aug 2012 05:25 AM PDT Scientists have discovered that an extract from a common plant in Pakistan may help treat breast cancer.

New molecular interactions behind the inhibition of TGF beta-signaling described Posted: 24 Aug 2012 05:24 AM PDT Researchers describe new molecular interactions behind the inhibition of TGF beta-signaling.

Astrocytes control the generation of new neurons from neural stem cells Posted: 24 Aug 2012 05:24 AM PDT Researchers from the Laboratory of astrocyte biology and CNS regeneration headed by Prof. Milos Pekny just published a research article in a prestigious journal Stem Cells on the molecular mechanism that controls generation of new neurons in the brain.

Wind concentrates pollutants with unexpected order in an urban environment Posted: 24 Aug 2012 05:19 AM PDT When blown by chaotic winds in an urban environment, pollutants tend to accumulate in specific neighborhoods.
