Birth and migration mysteries of cortex's powerful inhibitors, 'chandelier' cells solved Posted: 22 Nov 2012 12:29 PM PST Scientist have revealed the birth timing and embryonic origin of a critical class of inhibitory brain cells called chandelier cells, tracing the specific paths they take during early development into the cerebral cortex of the mouse brain. The work sheds light on the genetically programed, or "nature" part of the nature/nurture question of human development.

Scientists describe elusive replication machinery of flu viruses Posted: 22 Nov 2012 12:29 PM PST Scientists have made a major advance in understanding how flu viruses replicate within infected cells. The researchers used cutting-edge molecular biology and electron-microscopy techniques to "see" one of influenza's essential protein complexes in unprecedented detail. The images generated in the study show flu virus proteins in the act of self-replication, highlighting the virus's vulnerabilities that are sure to be of interest to drug developers.

Protein folding: Look back on scientific advances made as result of 50-year old puzzle Posted: 22 Nov 2012 12:29 PM PST Fifty years after scientists first posed a question about protein folding, the search for answers has led to the creation of a full-fledged field of research that led to major advances in supercomputers, new materials and drug discovery, and shaped our understanding of the basic processes of life, including so-called "protein-folding diseases" such as Alzheimer's, Parkinson's and type II diabetes.

Menopause: Relaxation good therapy for hot flushes Posted: 22 Nov 2012 08:28 AM PST Women who have undergone group therapy and learned to relax have reduced their menopausal troubles by half, according to new results.

Novel therapeutic advancement in search for heart muscle progenitor cells: New hope for heart attack patients Posted: 22 Nov 2012 08:28 AM PST Breakthrough in heart research: Medical researchers have discovered cell surface markers that enable the identification and isolation of living functional cardiovascular progenitor cells (CPCs). For the first time, therapeutically relevant CPCs can be derived from induced-pluripotent stem cells (iPS) cells. CPCs, which are typically only found in fetal development, can become all of the different cell types of the heart and can integrate into heart muscle tissue after injection.

Blind patient reads words stimulated directly onto retina: Neuroprosthetic device uses implant to project visual braille Posted: 22 Nov 2012 06:54 AM PST For the very first time researchers have streamed braille patterns directly into a blind patient's retina, allowing him to read four-letter words accurately and quickly with an ocular neuroprosthetic device.

Why older people struggle to read fine print: It's not what you think Posted: 22 Nov 2012 06:53 AM PST Unique research into eye-movements of young and old people while reading discovers that word recognition patterns change as we grow older.

Potential new treatment to prevent stroke Posted: 22 Nov 2012 06:51 AM PST Scientists may have discovered a new way to prevent strokes in high risk patients, according to research from the University of Warwick and University Hospitals Coventry and Warwickshire (UHCW).

First patients in US receive non-surgical device of sunken chest syndrome Posted: 21 Nov 2012 06:03 PM PST Surgeons have fitted a patient with a device that might eliminate the need for surgery in some patients with one of the world's most common chest deformities, pectus excavatum, often called sunken chest syndrome. Known as the vacuum bell, it works much like devices in body shops that use sustained vacuum to pop out a dent.

New drug overcomes resistance in patients with rare sarcoma, study suggests Posted: 21 Nov 2012 06:03 PM PST A new targeted drug demonstrated its ability to control metastatic gastrointestinal stromal tumor, an uncommon and life-threatening form of sarcoma, after the disease had become resistant to all existing therapies.

Just ten minutes in a car with a smoker boosts harmful pollutants by up to thirty percent Posted: 21 Nov 2012 06:03 PM PST Just ten minutes spent in the back seat of a car with a smoker in the front, boosts a child's daily exposure to harmful pollutants by up to 30 percent, reveals new research.
