Hubble spots a colorful lenticular galaxy Posted: 09 Nov 2012 04:02 PM PST The NASA/ESA Hubble Space Telescope has captured a beautiful galaxy that, with its reddish and yellow central area, looks rather like an explosion from a Hollywood movie. The galaxy, called NGC 5010, is in a period of transition. The aging galaxy is moving on from life as a spiral galaxy, like our Milky Way, to an older, less defined type called an elliptical galaxy. In this in-between phase, astronomers refer to NGC 5010 as a lenticular galaxy, which has features of both spirals and ellipticals.

Hunting neuron killers in Alzheimer's and traumatic brain injury Posted: 09 Nov 2012 08:15 AM PST Levels of the protein appoptosin in the brain skyrocket in Alzheimer's disease and traumatic brain injury. Appoptosin is known for helping the body make heme, the molecule that carries iron in the blood. Researchers discovered that excess heme leads to the overproduction of reactive oxygen species and triggers apoptosis, causing neurons to die.

New mechanism of action for PARP inhibitors discovered Posted: 09 Nov 2012 08:12 AM PST New understanding of how drugs called PARP inhibitors, which have already shown promise for the treatment of women with familial breast and ovarian cancers linked to BRCA mutations, exert their anticancer effects has led to the identification of ways in which the patient population that might benefit from PARP inhibitors could be expanded.

Link found between child prodigies and autism Posted: 09 Nov 2012 08:12 AM PST A new study of eight child prodigies suggests a possible link between these children's special skills and autism.

Tracking post-Sandy sewage Posted: 09 Nov 2012 08:12 AM PST With millions of gallons of raw sewage dumping into New Jersey waterways following Hurricane Sandy, scientists are using satellites to help predict the sludge's track into the ocean.

Extra chromosome 21 removed from Down syndrome cell line Posted: 09 Nov 2012 06:12 AM PST Scientists succeeded in removing the extra copy of chromosome 21 in cell cultures derived from a person with Down syndrome. Persons with this condition have three copies of this chromosome. The method would not lead to a treatment for Down syndrome, but could lead to treatments for some conditions associated with it, such as leukemia. Comparing tissue development from cell cultures from the same individual, with and without the extra chromosome, could provide clues to developmental delays and early aging problems in Down syndrome.

Gannets could be affected by offshore energy developments Posted: 09 Nov 2012 06:12 AM PST Scientists have discovered that proposed offshore renewable energy developments in the English Channel have the potential to affect the foraging behavior of northern gannets from Alderney in the Channel Islands.

High-quality personal relationships improve survival in women with breast cancer Posted: 09 Nov 2012 06:11 AM PST The quality of a woman's social networks -- the personal relationships that surround an individual -- appears to be just as important as the size of her networks in predicting breast cancer survival.

Drinking green tea with starchy food may help lower blood sugar spikes Posted: 09 Nov 2012 05:42 AM PST An ingredient in green tea that helps reduce blood sugar spikes in mice may lead to new diet strategies for people, according to food scientists.

Minimally invasive lymph node dissection in breast cancer has advantages over conventional surgery Posted: 09 Nov 2012 05:42 AM PST Axillary lymph node dissection is done in conjunction with lumpectomy or mastectomy to determine if breast cancer has spread to the adjoining lymph nodes. The conventional surgical approach leaves a surgical scar that is unattractive and can restrict range of motion in the shoulder joint. Also, squeezing and pulling the tumor during the breast operation can stimulate tumor cell metastases. A new study reports that an endoscopic technique, mastoscopic axillary lymph node dissection, can reduce these complications.

When identity is tied to former employer, unemployed report higher well-being Posted: 09 Nov 2012 05:41 AM PST Unemployed workers who continue to identify with their former employer report higher well-being even after being fired or laid off from the company, according to a new study.
