Fungus may provide clue about human response to changes in circadian rhythm

Humans are not the only species ruled by a circadian rhythm. Even simple organisms like moulds are governed by an inner clock. Studying red bread mould may teach us how our own internal clock works. This is exactly what the Centre for Organelle Research at the University of Stavanger, Norway is doing.

Five-stage reverse osmosis best for removal of hexavalent chromium from drinking water

The only way to learn if your water source has hexavalent chromium is to check with your public water supplier and request a water quality report, said NJIT Professor Taha Marhaba, a civil/environmental engineer. Most municipal or city engineers should be able to provide such a report upon request. Additional information specifically about hexavalent chromium levels may also be available.

Researchers discover recycling mechanism of signaling receptors

An international team of researchers led by Carnegie Mellon University's Manojkumar Puthenveedu has discovered the mechanism by which signaling receptors recycle, a critical piece in understanding signaling receptor function. Writing in the journal Cell, the team for the first time describes how a signaling receptor travels back to the cell membrane after it has been activated and internalized.

Researchers discover new way to prevent spread of cancer

Scientists now know that some cancer cells spread, or metastasize, throughout the body the old-fashioned way -- by using their feet. But researchers at Duke Cancer Institute have discovered a way to short-circuit their travels by preventing the development of these feet, called invadopodia. This discovery is even more important because preventing the development of these "feet" also eliminates the action of proteins present in the feet that burn through intact tissue and let cancer cells enter new cells.

RPCI forms Photolitec to develop photosensitizing compounds used in photodynamic therapy

Roswell Park Cancer Institute (RPCI) on December 13, 2010, announced the formation of Photolitec, LLC, a new life-sciences company at RPCI that will develop photosensitizing compounds used in photodynamic therapy (PDT). PDT is an innovative cancer treatment pioneered at RPCI by scientist Thomas J. Dougherty, Chief Emeritus of the Institute's Photodynamic Therapy Center.

DBS targets same class of neuronal cells that respond to physical exercise and drug Prozac

Shooting steady pulses of electricity through slender electrodes into a brain area that controls complex behaviors has proven to be effective against several therapeutically stubborn neurological and neuropsychiatric disorders. Now, a new study has found that this technique, called deep brain stimulation (DBS), targets the same class of neuronal cells that are known to respond to physical exercise and drugs such as Prozac.

Tru-D UV-C device effective in reducing pathogens on all environmental surfaces in hospital patient rooms

Results of an eight-month hospital study, "Room Decontamination with UV Radiation," were published in the October 2010 issue of "Infection Control and Hospital Epidemiology." The study evaluated the ability of an automated UV device, Tru-D, to decontaminate patient rooms contaminated with MRSA, VRE, C. difficile and a MDR strain of Acinetobacter baumannii.

New findings provide insight into brain development

St. Jude Children's Research Hospital investigators have identified key components of a signaling pathway that controls the departure of neurons from the brain niche where they form and allows these cells to start migrating to their final destination. Defects in this system affect the architecture of the brain and are associated with epilepsy, mental retardation and perhaps malignant brain tumors.

New simple diagnostic tool to detect dangerous viruses

Boston University researchers have developed a simple diagnostic tool that can quickly identify dangerous viruses like Ebola and Marburg. The biosensor, which is the size of a quarter and can detect viruses in a blood sample, could be used in developing nations, airports and other places where natural or man-made outbreaks could erupt.
