Stillbirths, infant deaths lead to anxiety, guilt and stress among obstetricians
Nearly one in 10 obstetricians in a new study has considered giving up obstetric practice because of the emotional toll of stillbirths and infant deaths. view more (2008-06-30)
Nanoscopic probes can track down and attack cancer cells
A researcher has developed probes that can help pinpoint the location of tumors and might one day be able to directly attack cancer cells. view more (2009-03-16)
New technique yields more detailed picture of chromatin structure
University of Illinois researchers have developed a technique for imaging cells under an electron microscope that yields a sharper image of the structure of chromatin, the tightly wound bundle of genetic material and proteins that makes up the chromosomes. view more (2008-04-17)
Gold nanoparticles, radiation combo may slow Alzheimer's
Chemists in Chile and Spain have identified a new approach for the possible treatment of Alzheimer's disease that they say has the potential to destroy beta-amyloid fibrils and plaque - hypothesized to contribute to the mental decline of Alzheimer's patients. view more (2006-01-05)
Club drugs inflict damage similar to traumatic brain injury
What do suffering a traumatic brain injury and using club drugs have in common"? University of Florida researchers say both may trigger a similar chemical chain reaction in the brain, leading to cell death, memory loss and potentially irreversible brain damage. view more (2007-11-30)
UCF technique promises to aid doctor's ability to identify, treat bacterial infections
A new technique developed by a University of Central Florida chemist will help physicians more quickly identify the bacterial infections patients have so they can be treated in hours instead of days. view more (2008-02-20)
UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the remote operation of micromachines a possibility. view more (2007-06-01)
Archaeologists rescue clues to ancient kingdom from the rising Nile
Archaeologists from the University of Chicago have discovered a gold processing center along the middle Nile, an installation that produced the precious metal sometime between 2000 and 1500 B.C. The center, along with a cemetery they discovered, documents extensive control by the first sub-Saharan kingdom, the kingdom of Kush. view more (2007-06-19)
The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes
Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential. view more (2009-01-05)
Humble shoelace tag carried more currency than gold on Columbus's travels
The humble device that prevents shoelaces from fraying was deemed to be worth more than gold by the indigenous Cubans who traded with Columbus's fleet. view more (2006-10-04)
Swishing once a day with mouthrinse poses no harm to dental work
People have been paying more attention to the effects certain liquids like coffee, citrus-containing drinks, and even toothbrushes have on teeth. Mouthrinses are no exception. view more (2007-01-12)
Turning green gunk to gold, anti-cancer gold
Combining synthetic chemistry techniques with a knowledge of the properties and actions of enzymes, scientists have been able to produce an exciting class of anti-cancer drugs originally isolated from blue-green algae. view more (2007-01-10)
Tightly packed molecules lend unexpected strength to nanothin sheet of material
Scientists at the University of Chicago and Argonne National Laboratory have discovered the surprising strength of a sheet of nanoparticles that measures just 50 atoms in thickness. view more (2007-07-23)
Using Life's Building Blocks to Control Nanoparticle Assembly
Using DNA, the molecule that carries life's genetic instructions, researchers at the U.S. Department of Energy's Brookhaven National Laboratory are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters. view more (2007-08-23)
Proteomics on a chip
'Golden approach' human proteine classification Proteomics on a chip Knowledge of the human proteome may provide us with even more insight than knowledge of DNA. This 'protein blueprint' of a human contains valuable information about cell properties and disease causes. A single cell, however, already consists of several thousands of proteines. To... view more... (2002-06-18)
Multi-laboratory study sizes up nanoparticle sizing
As a result of a major inter-laboratory study, the standards body ASTM International has been able to update its guidelines for a commonly used technique for measuring the size of nanoparticles in solutions. view more (2009-08-12)
CU-Boulder physics professors help create hottest temperature in universe
Two University of Colorado at Boulder physicists are part of a collaborative team working with the U.S. Department of Energy's Brookhaven National Laboratory in New York that have created the hottest temperature matter ever measured in the universe -- 7.2 trillion degrees Fahrenheit. view more (2010-02-18)
Treating drug-addicted doctors is good medicine
Doctors who become addicted to alcohol and other drugs can be treated successfully and returned to medical practice with the help of special programs that couple referral to treatment and monitoring with rapid responses to noncompliance, University of Florida researchers report. view more (2009-02-25)
New fuel cell catalyst uses 2 metals
Material scientists at Washington University in St. Louis have developed a technique for a bimetallic fuel cell catalyst that is efficient, robust and two to five times more effective than commercial catalysts. view more (2009-05-15)
The end of the line for existing stem cell research?
Time is short for scientists to respond to the call for comments on the National Institutes of Health (NIH) proposed guidelines for the use of human embryonic stem (ES) cell lines and their eligibility for federal funds. view more (2009-05-15)
