Some stress is good for you as it enhances neurogenesis

Posted: 18 Apr 2013 07:52 AM PDT

Overworked and stressed out? Look on the bright side. Some stress is good for you.
acute stress versus chronic stress

While too little stress can lead to boredom and depression, too much can cause anxiety and poor health. The right amount of acute stress, however, tunes up the brain and improves performance and health.

Astronomers discover that behind the most productive star systems more hide

Using the telescope network ALMA, astronomers have been able to determine the positions of more than 100 of the most prolific galaxies with unprecedented accuracy. The exact positions could help to solve the mystery of the supposedly extremely high star formation rates: Accordingly the amount of radiation released is not from one but from several galaxies - each of which have more moderate star formation rate and in accordance with theoretical models.

Liver disease: understanding it will enable the provision of better treatment

Posted: 18 Apr 2013 07:31 AM PDT

A certain number of patients hospitalised for cirrhosis complications soon develop a syndrome characterised by acute liver failure and/or the failure of other vital organs (ACLF)[1]. This syndrome had no specific diagnostic criteria hitherto.

Study to Treat Deadly Form of Thyroid Cancer Shows Promise, Mayo Clinic Says

Posted: 18 Apr 2013 07:19 AM PDT

A combination of therapies may prove to be a promising advance for the treatment of anaplastic thyroid cancer based on results of a phase I clinical trial, say researchers at Mayo Clinic in Florida.

New Computational Model Can Predict Breast Cancer Survival

Posted: 18 Apr 2013 07:14 AM PDT

Columbia Engineering researchers, led by Dimitris Anastassiou, Charles Batchelor Professor in Electrical Engineering and member of the Columbia Initiative in Systems Biology, have developed a new computational model that is highly predictive of breast cancer survival. The team, which won the Sage Bionetworks / DREAM Breast Cancer Prognosis Challenge for this work, published its results—"Development of a Prognostic Model for Breast Cancer Survival in an Open Challenge Environment"—in the April 17 issue of Science Translational Medicine.

High glucose levels could impair ferroelectricity in body’s connective tissues

Posted: 17 Apr 2013 11:17 AM PDT

High sugar levels in the body come at a cost to health. New research suggests that more sugar in the body could damage the elastic proteins that help us breathe and pump blood. The findings could have health implications for diabetics, who have high blood-glucose levels.

Researchers identify gene that regenerates heart tissue – critical finding for heart failure prevention

Posted: 17 Apr 2013 10:45 AM PDT

Researchers at UT Southwestern Medical Center have identified a specific gene that regulates the heart’s ability to regenerate after injuries.

The function of the gene, called Meis1, in the heart was not known previously. The findings of the UTSW investigation are available online in Nature.

Molecule treats leukemia by preventing cancer cell repair, Jackson Laboratory scientists report

Posted: 17 Apr 2013 08:08 AM PDT

Researchers at The Jackson Laboratory have identified a molecule that prevents repair of some cancer cells, providing a potential new "genetic chemotherapy" approach to cancer treatment that could significantly reduce side effects and the development of treatment resistance compared with traditional chemotherapy.

New keyboard for touchscreens

Posted: 17 Apr 2013 08:01 AM PDT

The research team of Antti Oulasvirta at the Max Planck Institute for Informatics has created a new keyboard called KALQ that enables faster thumb-typing on touchscreen devices. They used computational optimization techniques in conjunction with a model of thumb movement to search among millions of potential layouts before identifying one that yields superior performance. A user study confirmed that, after a short amount of practice, users could type 34% faster than they could with a QWERTY layout.

Lower education linked to premature death from malignant skin melanoma

Posted: 17 Apr 2013 07:42 AM PDT

There are socioeconomic differences in Sweden in survival amongst people with malignant skin melanoma, according to a new study published in the European Journal of Cancer. Melanoma patients with a lower educational background are much more likely to die of the disease.
