Researchers find cause of severe allergic reaction to cancer drug
Clinicians have been perplexed by the fact that some patients given the drug cetuximab-an immune-based therapy commonly used to treat persons diagnosed with head and neck cancer, or colon cancer-have a severe and rapid adverse reaction to the drug.   view more (2008-03-13)

MIT: engine on a chip promises to best the battery
MIT researchers are putting a tiny gas-turbine engine inside a silicon chip about the size of a quarter. The resulting device could run 10 times longer than a battery of the same weight can, powering laptops, cell phones, radios and other electronic devices.   view more (2006-09-26)

Scientists offer new view of photosynthesis
During the remarkable cascade of events of photosynthesis, plants approach the pinnacle of stinginess by scavenging nearly every photon of available light energy to produce food. Yet after many years of careful research into its exact mechanisms, some key questions remain about this fundamental biological process that supports all life on earth.   view more (2007-05-04)

Venerable ultraviolet satellite returns to operations
NASA's Far Ultraviolet Spectroscopic Explorer astronomy satellite is back in full operation, its aging onboard software control system rejuvenated and its mission extended by enterprising scientists and engineers after a near-death experience in December 2004.   view more (2006-02-24)

Mixing without side effects
The range of micromixers offered by IMM is also suitable for processes susceptible to fouling, especially in fine chemistry and pharmaceutics. The new „Interdigital-separation-layer-mixers" are replacing the present generation of „Separation-layer-mixers". The new mixer system has been adapted especially to industrial... view more...

New molecular force probe stretches molecules, atom by atom
Chemists at the University of Illinois have created a simple and inexpensive molecular technique that replaces an expensive atomic force microscope for studying what happens to small molecules when they are stretched or compressed.   view more (2009-03-30)

Targeting key proteins of carcinogenesis
Misfolded and disused proteins are eliminated by a cellular shredder called the proteasome. The cell labels the proteins it wants to dispose with Ubiquitin (Ub) in order to avoid the unwanted degradation of still needed proteins.   view more (2007-06-25)

New nanoscale engineering breakthrough points to hydrogen-powered vehicles
Researchers at the U.S. Department of Energy's Argonne National Laboratory have developed an advanced concept in nanoscale catalyst engineering - a combination of experiments and simulations that will bring polymer electrolyte membrane fuel cells for hydrogen-powered vehicles closer to massive commercialization.   view more (2007-03-06)

Nicotine exposure during development leads to hearing problems
Scientists know that children of women who smoke during pregnancy can develop hearing-related cognitive deficits. For the first time, researchers believe they have evidence that not only implicates nicotine as the culprit, but also shows what the substance does to the brain to cause these deficits.   view more (2006-07-19)

EARLY PROMISE OF SIMPLE TEST FOR DIAGNOSING MALIGNANT HYPERTHERMIA (p 1579)
German authors of a research letter in this week’s issue of THE LANCET describe the potential of a straightforward test for identifying people at risk of the often fatal reaction to general anaesthetics, a syndrome known as malignant hyperthermia. Malignant hyperthermia (MH) is a chain-reaction event triggered in susceptible individuals by... view more... (2002-05-01)

Diamonds Are Forever Revealing New Insights into Earth's Development
Diamonds will take center stage this month in countless wedding ceremonies and other celebrations. In addition to their usual role as symbols of enduring love and fidelity, diamonds are now also helping geologists unravel clues about how the earth's precious metal mineralization was formed and why diamonds and some of these metals are found in... view more...

When gold becomes a catalyst
Gold has always been perceived as a precious material: you win a gold medal when you prove to be the best in a competition; you only get a Gold credit card when you are a preferential customer, and the jewelry made of this material is amongst the most valuable.   view more (2006-06-23)

First direct evidence that environmental oestrogens affect sperm fertility
Researchers have found the first evidence that oestrogens from the environment, and also ones that occur naturally in our bodies, significantly affect the fertilising ability of sperm. Prof Lynn Fraser told the annual conference of the European Society of Human Reproduction and Embryology in Vienna today (Tuesday 2 July) that environmental... view more... (2002-06-30)

Scientists Uncover Critical Step in DNA Mutation
Scientists at the Georgia Institute of Technology have made an important step toward solving a critical puzzle relating to a chemical reaction that leads to DNA mutation, which underlies many forms of cancer.   view more (2006-08-24)

Careless talk costs lives in food allergy
A team of scientists, led by the Institute of Food Research (IFR) in the UK, has discovered an immune system malfunction that is likely to play a profound role in food allergy. Food allergy can be life threatening, but understanding the cause has remained a challenge for science. The international team has found that two types of cells stop... view more... (2004-05-05)

Caffeine limits blood flow to heart muscle during exercise
In healthy volunteers, the equivalent of two cups of coffee reduced the body's ability to boost blood flow to the heart muscle in response to exercise, and the effect was stronger when the participants were in a chamber simulating high altitude.   view more (2006-01-16)

Clouds: Lighter than air but laden with lead
By sampling clouds -- and making their own -- researchers have shown for the first time a direct relation between lead in the sky and the formation of ice crystals that foster clouds.   view more (2009-04-20)

LSUHSC study finds high-dose HBO2 therapy extends survival window after cardiopulmonary arrest
A ground-breaking study by researchers at the School of Medicine at LSU Health Sciences Center New Orleans published in the August 2008 issue of Resuscitation has major implications for the #1 cause of death of Americans -- sudden cardiac arrest.   view more (2008-07-16)

Older patients with 1 type of heart failure may receive little or no benefit from drugs
People over 80 years of age suffering from a certain type of heart failure do not appear to benefit from most commonly prescribed heart medications, according to a study conducted at the Cedars-Sinai Heart Institute and published in the March 15 issue of The American Journal of Cardiology.   view more (2009-03-12)

MIT biologists solve vitamin puzzle
Solving a mystery that has puzzled scientists for decades, MIT and Harvard researchers have discovered the final piece of the synthesis pathway of vitamin B12—the only vitamin synthesized exclusively by microorganisms.   view more (2007-03-23)
