Washington Getting a Summertime Air Quality Exam
Summer in the city can often mean sweltering "bad air days" that threaten the health of the elderly, children and those with respiratory problems. This summer the nation's capitol has been no stranger to such severe air-quality alerts.   view more (2006-08-07)

Cluster - new insights into the electric circuits of polar lights
Giant electrical circuits power the magical open-air light show of the auroras, forming arcs in high-latitude regions like Scandinavia. New results obtained thanks to ESA's Cluster satellites provide a new insight into the source of the difference between the two types of electrical circuits... view more (2007-02-12)

Patterns on tropical marine mollusk shell mirror gene expression patterns
Scientists have identified a group of genes that control the formation of shapes and colour patterns on the shell of the tropical marine mollusc referred to as 'abalone'.   view more (2006-11-22)

The inside dope
Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce materials for modern electronics, small amounts of impurities are introduced into silicon - a process called doping.   view more (2007-07-27)

NIST team proves bridge from conventional to molecular electronics possible
Researchers at the National Institute of Standards and Technology (NIST) have set the stage for building the "evolutionary link" between the microelectronics of today built from semiconductor compounds and future generations of devices made largely from complex organic molecules.   view more (2008-03-19)

NC State Engineers Discover Nanoparticles Can Break On Through
In a finding that could speed the use of sensors or barcodes at the nanoscale, North Carolina State University engineers have shown that certain types of tiny organic particles, when heated to the proper temperature, bob to the surface of a layer of a thin polymer film and then can reversibly... view more (2008-09-17)

Getting closer to the Lord of the Rings
This time next year, ESA's Huygens spaceprobe will be descending through the atmosphere of Saturn's largest moon, becoming the first spacecraft to land on a body in the outer Solar System. Earlier this month, the giant ringed planet Saturn was closer to Earth than it will be for the next thirty... view more (2004-01-16)

Allergy battle could be won in five years, says scientist
Researchers, working with colleagues at St George's, University of London, are developing drugs designed to stop allergens from entering the body, so rendering them harmless.   view more (2006-07-13)

Neurons find their place in the developing nervous system with the help of a sticky molecule
The brain, that exquisite network of billions of communicating cells, starts to take form with the genesis of nerve cells. Most newborn nerve cells, also called neurons, must travel from their birthplace to the position they will occupy in the adult brain.   view more (2006-04-26)

Phase II study shows combination improves survival of metastatic melanoma patients
Two chemotherapy drugs combined with an agent that prevents the growth of blood vessels significantly delayed the spread of tumors in patients with metastatic melanoma.   view more (2007-06-04)

Basque Country University researchers publish two articles in Nature on latest discoveries on Venus
Nature journal has published a series of articles devoted to the new discoveries by the European Space Agency's (ESA) Venus Express space probe made on our neighbouring planet.   view more (2007-12-03)

Blood vessel cells are instructed to form tube-like structures
How do blood vessel cells understand that they should organise themselves in tubes and not in layers? A research group from Uppsala University shows for the first time that a special type of "instructor" molecule is needed to accomplish this. These findings, published in the scientific... view more (2008-08-29)

Researchers discover method for mass production of nanomaterial graphene
Graphene is a perfect example of the wonders of nanotechnology, in which common substances are scaled down to an atomic level to uncover new and exciting possibilities.   view more (2008-11-11)

Lipid plays big role in embryonic development
A little-known lipid plays a big role in helping us grow from a hollow sphere of stem cells into human beings, researchers have found.   view more (2007-02-05)

500,000 years of climate history stored year by year
The bottom of Turkey's Lake Van is covered by a layer of mud several hundreds of metres deep. For climatologists this unprepossessing slime is worth its weight in gold: summer by summer pollen has been deposited from times long past.   view more (2007-03-15)

Magnetic field uses sound waves to ignite sun's ring of fire
Sound waves escaping the sun's interior create fountains of hot gas that shape and power a thin region of the sun's atmosphere which appears as a ruby red "ring of fire" around the moon during a total solar eclipse, according to research funded by the National Science Foundation (NSF) and... view more (2007-05-30)

Television just got brighter: UCLA engineers are obsessed with the next generation of LEDs
Two researchers at the UCLA Henry Samueli School of Engineering and Applied Science want to make sure future generations of plasma TV watchers will see games like the upcoming NBA Finals in the brightest, most beautiful color possible - for a lot less money.   view more (2007-05-17)

Adult stem cells activated in mammalian brain
Adult stem cells originate in a different part of the brain than is commonly believed, and with proper stimulation they can produce new brain cells to replace those lost to disease or injury, a study by UC Irvine scientists has shown.   view more (2008-07-25)

Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia.   view more (2005-12-20)

Alternatives to the use of nitrate as a fertiliser
In order to develop sustainable agricultural production, what is required is a study of nitrogenated sources as alternatives to the nitrates that predominate in agricultural soils and that have a greater contaminant capacity.   view more (2006-04-19)

The light and dark of Venus
Venus Express has revealed a planet of extraordinarily changeable and extremely large-scale weather. Bright hazes appear in a matter of days, reaching from the south pole to the low southern latitudes and disappearing just as quickly.   view more (2008-02-22)

100 million years AD
Jan Zalasiewicz, a lecturer in geology at the University of Leicester, has published a new study looking at the lasting impression made by mankind -100 million years hence.   view more (2008-09-26)

NASA's Advanced Technology Peers Deep Inside Hurricanes
Determined to understand why some storms grow into hurricanes while others fizzle, NASA scientists recently looked deep into thunderstorms off the African coast using satellites and airplanes.   view more (2007-03-07)

Invisible for Electrons
As thin as it gets: the carbon membranes recently created by Max Planck scientists are only one atom thick. For electrons, such membranes are almost completely transparent-using an electron microscope, scientists may thus be able to examine absorbed individual molecules on the membranes, and image... view more (2007-03-07)

Findings a step toward making new optical materials
Chemical engineers have developed a "self-assembling" method that could lead to an inexpensive way of making diamondlike crystals to improve optical communications and other technologies.   view more (2008-04-23)
