Pitt, NETL researchers report molecular chain reaction thought to be impossible
People said it couldn't be done, but researchers from the University of Pittsburgh and the U.S. Department of Energy National Energy Technology Laboratory (NETL) in Pittsburgh demonstrated a molecular chain reaction on a metal surface, a nanoscale process with sizable potential in areas from nanotechnology to developing information storage... view more...

Scientists uncover how hormones achieve their effects
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory [EMBL]. view more (2007-10-23)
Historians help compile record of 50,000 lives
Scholars at the University of Essex have contributed 75 biographies to the new Oxford Dictionary of National Biography, a 60-volume publication charting more than 50,000 lives. Researchers from six departments and centres at the University were among more than 12,500 contributors to the British Academy-funded project. view more (2005-02-01)
Old-fashioned friendliness trumps incentives among supply chain partners
Cordiality and mutually beneficial arrangements can be more important than hard-negotiated deals when it comes to cementing strong working relationships among supply chain partners. view more (2008-11-24)
A molecular ripcord for chemical reactions
Researchers at Eindhoven University of Technology (TU/e) have developed an entirely new method for starting chemical reactions. view more (2009-04-07)
Controlling for size may also prevent cancer
Scientists at Johns Hopkins recently discovered that a chemical chain reaction that controls organ size in animals ranging from insects to humans could mean the difference between normal growth and cancer. view more (2007-09-21)
Anticancer drugs might be of benefit to sickle-cell patients
Sickle cell disease (SCD) is an inherited blood disorder caused by a genetic mutation that leads to the generation of a mutant form of the beta-globin chain of hemoglobin (Hb). view more (2007-12-07)
Focus on opticians shows chain store pricing policies can save independents
Big chain stores setting their prices on a national rather than local basis can help independent retailers survive, according to new research funded by the Economic and Social Research Council (ESRC). view more (2006-11-08)
For fats, longer may not be better
Researchers have uncovered why some dietary fats, specifically long-chain fats, such as oleic acid (found in olive oil), are more prone to induce inflammation. view more (2009-01-09)
Snails snack on poison metals
SOILS tainted with heavy metals from industrial pollution and sewage sludge may poison organisms that live in the soil far more readily than thought. The finding raises fears that unexpectedly high levels of toxins are getting into the food chain. Contaminated soils are given hazard ratings that are based on the key assumption that organisms can... view more... (2002-12-18)
Ultrafast laser spectrometer measures heat flow through molecules
Global warming isn't the only heat scientists are feeling. Another area in which heat flow is becoming crucial is the field of molecular electronics, where long-chain molecules attached to tiny electrodes are used to transport and switch electrons. view more (2007-08-10)
Antibiotic resistant bacteria found in fertilizer
Vancomycin resistant enterococci (VRE) have been found in sewage sludge, a by-product of waste-water treatment frequently used as a fertilizer. view more (2009-05-29)
NIST scientists use electron beam to unravel the secrets of an 'atomic switch'
Scientists at the Commerce Department's National Institute of Standards and Technology (NIST) have used a beam of electrons to move a single atom in a small molecule back and forth between two positions on a crystal surface, a significant step toward learning how to build an "atomic switch" that turns electrical signals on and off in... view more...

BIOTECHNICA 2003: At the Pulse of the Chip Lab
The clinical and industrial analytics as well as diagnostics show an increasing demand for more sensitive and more rapid detection methods using smallest sample volumes. Within the BMBF joint project "MODULAB" a „chip-based-lab" construction kit is developed in which all the necessary working steps can be performed in separate... view more... (2003-10-07)
Grains and lamb offer new sources of omega-3
CSIRO research on grains and lamb aimed at developing new dietary sources of long-chain omega-3 oils will be presented at the World Congress on Oils and Fats in Sydney this week. view more (2009-10-01)
Folding Proteins on a Computer
Proteins only function when properly folded In order for enzymatic reactions to proceed correctly, the enzyme and substrate must fit together as precisely as a lock and key. The function of the enzyme and protein is determined by the structure of the latter. The chain of amino acids that makes up the protein thus has to fold in a very precise... view more... (2001-01-19)
Research measures movement of nanomaterials in simple model food chain
New research shows that while engineered nanomaterials can be transferred up the lowest levels of the food chain from single celled organisms to higher multicelled ones, the amount transferred was relatively low and there was no evidence of the nanomaterials concentrating in the higher level organisms. view more (2008-06-02)
Carbon turns over much faster through basal food-chain levels in aquatic than in terrestrial ecosystems
Global temperatures have increased dramatically over the past century, which is causing major impacts on climate patterns, ocean circulation and wildlife preservation. The increase in temperature is largely due to a rise of anthropogenic emissions of greenhouse gases, of which CO2 is one of the most important. To understand the capacity of... view more...

Shield against assassin`s poison
Just a trace of ricin on the sharpened tip of an umbrella was enough to kill the Bulgarian dissident Georgi Markov, after an infamous attack on London`s Waterloo Bridge in 1978. Now a vaccine against this lethal toxin could soon be available - and it may be needed. "A big stash of ricin was found in the caves of Afghanistan," says Ellen Vitetta of... view more...

Tiny molecule controls stress-induced heart disease
A tiny snippet of RNA, a chemical cousin of DNA, controls damage to the heart under several types of stress, researchers at UT Southwestern Medical Center have found. view more (2007-03-23)
