Anesthetic could be alternative to hormones and other medications for hot flashes

The technique could give women who cannot or prefer not to take hormones or other medications an effective treatment alternative.
Women may perceive men with wider faces as more dominant and more attractive for short-term relationships
Date: Feb-07-2014New study in Psychological Science, a journal of the Association for Psychological Science."Our study shows that within three minutes of meeting in real life, women find more dominant, wider-faced men attractive for short-term relationships, and want to go on another date with them," says psychological scientist and lead researcher Katherine Valentine of Singapore Management University.According to Valentine, there's considerable academic debate about whether physical dominance is advantageous in mating - that is, actually attractive to women.

Enabling the blind to 'see' colors and shapes with EyeMusic Sensory Substitution Device
Date: Feb-07-2014Using auditory or tactile stimulation, Sensory Substitution Devices (SSDs) provide representations of visual information and can help the blind "see" colors and shapes. SSDs scan images and transform the information into audio or touch signals that users are trained to understand, enabling them to recognize the image without seeing it.Currently SSDs are not widely used within the blind community because they can be cumbersome and unpleasant to use.
3D mapping biopsy found pockets of prostate cancer previous technique had missed
Date: Feb-07-2014Ultrasound-guided biopsies miss prostate cancers that are detected by the slightly more expensive and slightly more invasive 3D mapping biopsies. For example, in a 2006 study of 180 men diagnosed with early stage prostate cancer via ultrasound-guided biopsy, nearly a quarter were upgraded to a more clinically significant stage of disease after 3D mapping biopsy found pockets of cancer the first technique had missed. Now, a University of Colorado Cancer Center study reports the locations of these most-missed pockets of prostate cancer.
Clues to the mystery of the need for sleep
Date: Feb-07-2014All creatures great and small, including fruitflies, need sleep. Researchers have surmised that sleep - in any species - is necessary for repairing proteins, consolidating memories, and removing wastes from cells. But, really, sleep is still a great mystery.The timing of when we sleep versus are awake is controlled by cells in tune with circadian rhythms of light and dark. Most of the molecular components of that internal clock have been worked out.

Long-term survival no different among those severely injured by violence vs. accident
Date: Feb-07-2014People seriously injured by violence are no more likely to die in the years after they are shot, stabbed or beaten than those who are seriously injured in accidents, Johns Hopkins researchers have found.In a report on research published online in the Annals of Surgery, the Johns Hopkins scientists say that lifesaving trauma care is succeeding in extending the lives of many of the most severely injured, regardless of cause.

Male obesity could dictate future colon screenings
Date: Feb-07-2014Obesity is a known risk factor for many cancers including colon cancer, yet the reasons behind the colon cancer link have often remained unclear.A Michigan State University study is shedding more light on the topic and has shown that elevated leptin - a fat hormone - higher body mass index and a larger waistline in men is associated with a greater likelihood of having colorectal polyps, precancerous growths linked to colon cancer.
