Nerve sparing helps most prostate cancer patients to have same orgasms as before surgery

Posted: 13 Feb 2012 07:02 AM PST

The vast majority of men who have a prostate cancer operation can retain their ability to orgasm if the surgery is carried out without removing the nerves that surround the prostate gland like a hammock, according to a study in the February issue of the urology journal BJUI.

Pharmaceuticals from Crab Shells

Usually, mould fungi are nothing to cheer about – but now they can be used as “chemical factories”. Scientists at the Vienna University of Technology have succeeded in introducing bacterial genes into the fungus Trichoderma, so that the fungus can now produce important chemicals for the pharmaceutical industry. The raw material used by the fungus is abundant - it is chitin, which makes up the shells of crustaceans.

Cognitive Impairment in Older Adults Often Unrecognized in the Primary Care Setting

A new study published in the Journal of the American Geriatrics Society reveals that brief cognitive screenings combined with offering further evaluation increased new diagnoses of cognitive impairment in older veterans two to three fold.

Rehabilitation of maculopathy patients: A simple, non-invasive treatment method

Posted: 13 Feb 2012 05:59 AM PST

A new study reports a simple and non-invasive treatment method in the rehabilitation of maculopthy patients. Maculopathy is a pathological condition of a small area at the center of the retina called macula, that is associated with highly sensitive and accurate vision.

Many Lung Cancer Patients Get Radiation Therapy That May Not Prolong Their Lives

A new study has found that many older lung cancer patients get treatments that may not help them live longer. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings suggest that physicians should not routinely use radiation after surgery to treat lung cancer that is advanced but has not widely spread, at least in older patients.

Cancer Rate Four Times Higher in Children with Juvenile Arthritis

New research reports that incident malignancy among children with juvenile idiopathic arthritis (JIA) is four times higher than in those without the disease.

Ordered planar polymers created for the first time

Scientists under the direction of ETH Zurich have created a minor sensation in synthetic chemistry. They succeeded for the first time in producing regularly ordered planar polymers that form a kind of “molecular carpet” on a nanometre scale.

Adoptees at higher suicide risk if both biological and adoptive parents have psychiatric problems

Posted: 13 Feb 2012 04:24 AM PST

A new study from Karolinska Institutet and Johns Hopkins University in Baltimore, USA, shows that adopted children from a biological family with experience of suicide were more likely to themselves attempt suicide if their adoptive mother had also been treated for a psychiatric disorder. The results, which are presented in the scientific periodical The American Journal of Psychiatry, suggest that the genes can be affected by environmental factors, according to the researchers.

A new technique identifies corpses by comparing the skull with a picture of the subject alive

Posted: 13 Feb 2012 04:14 AM PST

University of Granada researchers have developed a new forensic identification technique that compares the skull with one or several pictures of the subject while still alive. This system is based on the forensic identification technique known as craniofacial superimposition; this technique involves analysing the morphology of the face by locating a set of reference points either on the skull (craniometric points) and on a picture (somatometric points) of the subject alive.

A Mitosis Mystery Solved: How Chromosomes Align Perfectly in a Dividing Cell

Posted: 12 Feb 2012 08:52 PM PST

To solve a mystery, sometimes a great detective need only study the clues in front of him. Like Agatha Christie’s Hercule Poirot and Arthur Conan Doyle’s Sherlock Holmes, Tomomi Kiyomitsu used his keen powers of observation to solve a puzzle that had mystified researchers for years: in a cell undergoing mitotic cell division, what internal signals cause its chromosomes to align on a center axis?

Researchers Develop Method to Examine Batteries—From the Inside

Posted: 12 Feb 2012 06:05 PM PST

There is an ever-increasing need for advanced batteries for portable electronics, such as phones, cameras, and music players, but also to power electric vehicles and to facilitate the distribution and storage of energy derived from renewable energy sources. But, once a battery fails, there are no corrective measures—how do you look inside a battery without destroying it?
