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.

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.

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.

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.

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.

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.
