Vitamin A pushes breast cancer to form blood vessel cells
Researchers at Georgetown University Medical Center have discovered that vitamin A, when applied to breast cancer cells, turns on genes that can push stem cells embedded in a tumor to morph into endothelial cells. These cells can then build blood vessels to link up to the body's blood supply,... view more (2008-07-16)

Nature's process for nitrogen fixation caught in action
Nitrogen gas is converted to ammonia fertilizer by a chemical process that involves high temperature and high pressure. Nature does the same thing at ambient temperature and pressure. The process, called nitrogen fixation, is essential to life as it provides nutrients to plant life.   view more (2006-11-10)

Engineers create gecko-inspired, high-friction micro-fibers
Inspired by the remarkable hairs that allow geckos to hang single-toed from sheer walls and scamper along ceilings, a team of researchers led by engineers at the University of California, Berkeley, has created an array of synthetic micro-fibers that uses very high friction to support loads on... view more (2006-08-23)

Nanoparticle Assembly Enters the Fast Lane
The speed of nanoparticle assembly can be accelerated with the assistance of the molecule that carries life's genetic instructions, DNA, a team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory recently found.   view more (2006-10-12)

UT Southwestern researchers identify new targets for RNAs that regulate genes
Tiny strands of genetic material called RNA - a chemical cousin of DNA - are emerging as major players in gene regulation, the process inside cells that drives all biology and that scientists seek to control in order to fight disease.   view more (2008-07-07)

Hope Diamond's phosphorescence key to fingerprinting
Shine a white light on the Hope Diamond and it will dazzle you with the brilliance of an amazing blue diamond. Shine an ultraviolet light on the Hope Diamond and the gem will glow red-orange for about five minutes.   view more (2008-01-08)

Interferons For Treatment Of SARS? (p 293)
Authors of a research letter in this week's issue of THE LANCET suggest that recombinant interferons - synthetic versions of naturally occurring compounds of the immune system - could be a an effective treatment for Severe Acute Respiratory Syndrome (SARS). Although antivirals are probably... view more (2003-07-23)

Pycnogenol delays glucose absorption 190 times more potently than prescription medication
A new study to be published in an upcoming edition of the journal of Diabetes Research and Clinical Practice reveals that French maritime pine tree extract known as Pycnogenol® (pic-noj-en-all) delays the uptake of glucose from a meal 190 times more than prescription medications, preventing the... view more (2007-02-08)

Gold bowties may shed light on molecules and other nano-sized objects
One of the great challenges in the field of nanotechnology is optical imaging-specifically, how to design a microscope that produces high-resolution images of the nano-sized objects that researchers are trying to study.   view more (2005-08-31)

Vitamin D signals to prevent bone loss during osteoporosis
The risk of bone fracture resulting from falls increases as we age due to bone loss and osteoporosis. Physicians have routinely prescribed vitamin D and vitamin D-related drugs to retard bone loss, but until now, little was known about the specific targets of vitamin D in bone.   view more (2006-01-20)

Wood to replace oil in building polymers
A new type of polymers can be produced in a more environmentally friendly way, using wood instead of oil as a raw material, according to research at the Royal Institute of Technology (KTH) in Stockholm, Sweden. The next step is to replace the wood with the process water from the pulp industry. This... view more (2003-06-12)

Erectile dysfunction in diabetes is due to selective defect in the brain
A new study sheds additional light on how erectile dysfunction (ED) interacts with diabetes. The study is another step in uncovering the link between the two disorders, and may lead to improved efficacy in treatments.   view more (2007-03-16)
