A filter that enhances the power of communications satellites
Researchers at the Public University of Navarre are designing and developing a filter that enhances the power of communications satellites for the European Space Agency. The filter enables the reduction, by a factor of a million, interference produced by what is known as the "Field Emission Effect". view more (2005-02-03)
New brain-chemistry differences found in depressed women
A new brain study finds major differences between women with serious depression and healthy women in a brain-chemical system that's crucial to stress and emotions. view more (2006-11-07)
HERA GETS GOING WITH ELECTRONS
The Hadron Electron Ring Accelerator (HERA) at the DESY laboratory in Hamburg is about to begin operations for 1998 with a return to electrons. Since 1993, the machine has been producing head-on collisions between high-energy protons and positrons - the antimatter equivalent of electrons. Now it is ready to get going with electrons again. view more (1998-08-11)
Quantum dot lasers — 1 dot makes all the difference
Physicists at the National Institute of Standards and Technology (NIST) and Stanford and Northwestern Universities have built micrometer-sized solid-state lasers in which a single quantum dot can play a dominant role in the device's performance. view more (2007-04-13)
Women At Greater Risk Of Brain-Cell Damage From Long-Term Ecstasy Use
Authors of a Dutch study in this week's issue of THE LANCET conclude that long-term ecstasy use-especially among women-could have serious negative effects on specific cells in the brain. The study also suggests that the adverse effects of ecstasy use can sometimes be reversed among people who stop using the drug. Ecstasy is a popular recreational... view more... (2001-11-28)
Targeted nanospheres find, penetrate, then fuel burning of melanoma
Hollow gold nanospheres equipped with a targeting peptide find melanoma cells, penetrate them deeply, and then cook the tumor when bathed with near-infrared light, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reported in the Feb. 1 issue of Clinical Cancer Research. view more (2009-02-02)
Chinese acupuncture affects brain's ability to regulate pain, UM study shows
Acupuncture has been used in East-Asian medicine for thousands of years to treat pain, possibly by activating the body's natural painkillers. But how it works at the cellular level is largely unknown. view more (2009-08-10)
Early results from Alzheimer's neuroimaging studies could speed research
Alzheimer's disease researchers may be able to reduce the time and expense associated with clinical trials. view more (2007-06-13)
PET and Bioluminescent Imaging Aid Evaluation of Stem Cells' Potential for New Ways to Treat Disease
Using positron emission tomography (PET) imaging with bioluminescence-the light produced by a chemical reaction within an organism-researchers are starting to understand the behavior of transplanted or implanted stem cells that may one day be used to develop new treatments for disease. view more (2007-12-07)
Serotonin receptor: A rheostat in brain for emotion that may be linked to depression
Although drugs that target the brain's serotonin system are widely used to treat depression, the basic biological mechanism by which they help to alleviate symptoms is poorly understood. view more (2006-10-02)
Key neural system at risk from fetal alcohol exposure
In a study of adult monkeys who were exposed to moderate amounts of alcohol in utero, scientists have found that prenatal exposure to alcohol-even in small doses-has pronounced effects on the development and function later in life of the brain's dopamine system, a critical component of the central nervous system that regulates many regions of the... view more...

U.S. Air Force Technology Helps Scientists Understand Plant Root Function
The McClellan Nuclear Radiation Center (MNRC) in Sacramento, CA was developed by the U.S. Air Force to detect corrosion and defects in aircraft structure using an imaging technique called neutron radiography. This technique is currently helping soil scientists understand the function of plant roots and their uptake of water and nutrients. view more (2008-09-09)
New materials for high efficiency organic solid state lighting
A new organic molecule developed by Pacific Northwest National Laboratory scientists may significantly improve the efficiency of organic solid state lighting. Direct conversion of electricity to light in "solid state" thin films of organic molecules occurs in organic light emitting devices which can be far more efficient than... view more... (2006-03-30)
Cultural stimulation changes the organization of the human brain
The development of a neurosciences project on the influence of culture on the organization of the functions of the brain, by Alexandre Castro-Caldas, brings us a perspective of life-long evolution and adaptation, demonstrating the importance of knowledge acquired at school age. The analysis of the acquisition and performance in the areas of... view more... (2002-11-18)
Scripps research scientists find new link between insulin and core body temperature
A team led by scientists at The Scripps Research Institute have discovered a direct link between insulin-a hormone long associated with metabolism and metabolic disorders such as diabetes-and core body temperature. view more (2009-11-20)
An invisible threat could change Britain's landscapes
People and farm animals are helping an invisible pollutant to change the types of plants that grow in Britain, particularly in remote and rural regions such as the Lake District. view more (2005-02-11)
Study reveals biochemical signature of cocaine craving in humans
Using sophisticated brain-imaging techniques at the U.S. Department of Energy's Brookhaven National Laboratory, scientists from the National Institute on Drug Abuse (NIDA), Brookhaven Lab, and the University of Pennsylvania have uncovered the brain chemistry that underlies such "cue-induced" craving in cocaine addicts. view more (2006-06-14)
Another first for Europe: an electric car with extended range and no pollution
The international symposium takes place in Brussels from 29 September to 3 October and has been organised by the Commission on the topic "A future for the city". Some 1 500 specialists in electric and hybrid vehicles are expected to attend to see the latest technological developments designed to improve this mode of transport during the coming... view more...

Thinking the pain away? Study shows the brain's painkillers may cause 'placebo effect'
Just thinking that a medicine will relieve pain is enough to prompt the brain to release its own natural painkillers, and soothe painful sensations, a new University of Michigan study finds. view more (2005-08-24)
Prepare CO2 capture and storage now for greater environmental benefit later
CO2 capture and storage can make a major contribution to CO2 reduction in the Netherlands. By the mid-21st century 80 to 110 million tonnes of CO2 per year could be avoided in the sectors energy, industry and transport. This is half of the current CO2 emission. Moreover, this can be realised against acceptable costs concludes Dutch researcher Kay... view more... (2007-04-16)
