Coffee and tea may contribute to a healthy liver Posted: 16 Aug 2013 12:30 PM PDT Scientists suggest that increased caffeine intake may reduce fatty liver in people with non-alcoholic fatty liver disease.

Aggressive lymphoma: Low doses of approved drug switches on pathway that allows chemotherapy to kill cancer Posted: 16 Aug 2013 10:04 AM PDT Patients with an aggressive lymphoma that often relapses and kills within two years experienced a remission of their cancer and stayed disease-free as long as 28 months after taking a commercially-available drug that made chemotherapy more effective.

Nanosensors could aid drug manufacturing Posted: 16 Aug 2013 10:03 AM PDT Chemical engineers have discovered that arrays of billions of nanoscale sensors have unique properties that could help pharmaceutical companies produce drugs -- especially those based on antibodies -- more safely and efficiently.

How DNA repair helps prevent cancer Posted: 16 Aug 2013 10:03 AM PDT DNA damage is a natural biological occurrence that happens every time cells divide and multiply; thus, DNA repair is important for preserving the composition of the genome. Researchers are using supercomputers to study the molecular-level dynamics involved in this process.

Autistic kids who best peers at math show different brain organization Posted: 16 Aug 2013 10:03 AM PDT Children with autism and average IQs consistently demonstrated superior math skills compared with nonautistic children in the same IQ range, according to a new study.

Drug dosing for older heart patients should differ Posted: 16 Aug 2013 09:53 AM PDT Older heart patients present unique challenges for determining the optimal dosages of medications, so a new study offers some rare clarity about the use of drugs that are used to treat patients with heart attacks.

Tumors form advance teams to ready lungs for spread of cancer Posted: 16 Aug 2013 09:53 AM PDT An advance team of molecules produced by the primary tumor sets off a series of events that create a network of nurturing blood vessels for arriving primary tumor cells to set up shop.

Preferred play for children with autism Posted: 16 Aug 2013 09:53 AM PDT Play preferences of children with autism spectrum disorder were observed in a community-based museum designed to enable children to choose their preferred play activity. In this naturalistic setting, children with ASD preferred play options with a strong sensory component.

Middle-aged men, women not equal in heart attack risk Posted: 16 Aug 2013 06:48 AM PDT High cholesterol levels are much more risky for middle-aged men than middle-aged women when it comes to having a first heart attack, a new study of more than 40,000 Norwegian men and women has shown.

Molecular explanation for degenerative disease proposed Posted: 16 Aug 2013 06:46 AM PDT Scientists have shed new light on the origins and molecular causes of age related degenerative conditions including motor neuron disease. The new perspective provided by this work may lead the way to new treatments and early diagnoses.

Soft drinks linked to behavioral problems in young children Posted: 16 Aug 2013 06:46 AM PDT Americans buy more soft drinks per capita than people in any other country. These drinks are consumed by individuals of all ages, including very young children. Although soft drink consumption is associated with aggression, depression, and suicidal thoughts in adolescents, the relationship had not been evaluated in younger children. A new study finds that aggression, attention problems, and withdrawal behavior are all associated with soft drink consumption in young children.

Lymph nodes with location memory Posted: 14 Aug 2013 09:47 AM PDT Regulatory T cells (or "Tregs" for short) play a central role in the human immune system: They guide all of the other immune cells and make sure they are tolerant of the body's own cells and harmless foreign substances. How Tregs become Tregs in the first place has been only incompletely understood -- until now. Scientists have recently gleaned important new insights into the workings of these cells.

Bacteria commonly found in drinking water creates conditions which enable other -- potentially harmful -- bacteria to thrive Posted: 14 Aug 2013 09:43 AM PDT Bacteria commonly found in drinking water creates conditions which enable other -- potentially harmful -- bacteria to thrive.
