Researchers using Arecibo Telescope discover never-before-seen pulsar blasts in Crab Nebula
Astronomers and physicists using the Cornell-managed Arecibo Telescope in Puerto Rico have discovered radio interpulses from the Crab Nebula pulsar that feature never-before-seen radio emission spectra. This leads scientists to speculate this could be the first cosmic object with a third magnetic pole. view more (2007-01-09)
Reversing and accelerating the speed of light
Physicist Costas Soukoulis and his research group at the U.S. Department of Energy's Ames Laboratory on the Iowa State University campus are having the time of their lives making light travel backwards at negative speeds that appear faster than the speed of light. view more (2006-07-24)
Tiny holes offer surprising insights
Researchers from Berlin and Seoul store light in plasmonic crystals view more (2005-03-04)
Forced evolution: Can we mutate viruses to death?
It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence. The killer disease? Still a fiction. The drug? It could become a reality thanks to a new study by Rice University bioengineers. view more (2008-11-11)
Camera flash turns an insulating material into a conductor
An insulator can now be transformed to conduct electricity by an ordinary camera flash. view more (2009-08-13)
Subterfuge, counter-surveillance and assassination: The body's fight with cervical cancer
The virus responsible for most cases of cervical cancer has a serious weakness which may provide hope for new treatments for the disease. view more (2008-03-24)
Marsupial genome reveals insights into mammalian evolution
The genetic code of marsupials has now been documented for the first time. An international team led by Kathy Belov from the University of Sydney's Faculty of Veterinary Science published an analysis of the marsupial genome in the open access journal PLoS Biology. view more (2006-01-31)
LANL/NIST team sends quantum encryption 'keys' over record distances
Using an innovative sensor for detecting single photons, the smallest particles of light, scientists from Los Alamos National Laboratory (LANL), the National Institute of Standards and Technology (NIST) and Albion College (Albion, Mich.) have set two significant distance records for distributing "keys" (or codes) for quantum encryption,... view more...

New insights into how lasers cut flesh
Lasers are at the cutting edge of surgery. From cosmetic to brain surgery, intense beams of coherent light are gradually replacing the steel scalpel for many procedures. view more (2007-10-26)
Genomics-based vaccine could prevent deadly cattle disease
Every year, East Coast fever destroys the small farmer's dream of escaping poverty in Africa. Killing more than a million cattle and costing some $200 million annually, this tick-borne disease rages across a dozen countries in eastern and central Africa. view more (2006-02-14)
Master gene that switches on disease-fighting cells identified by scientists
The master gene that causes blood stem cells to turn into disease-fighting 'Natural Killer' (NK) immune cells has been identified by scientists, in a study published in Nature Immunology today. view more (2009-09-14)
From zero to a billion electron volts in 3.3 centimeters
In a precedent-shattering demonstration of the potential of laser-wakefield acceleration, scientists at the Department of Energy's Lawrence Berkeley National Laboratory, working with colleagues at the University of Oxford, have accelerated electron beams to energies exceeding a billion electron volts (1 GeV) in a distance of just 3.3 centimeters. view more (2006-09-25)
Researchers use chemical from medicinal plants to fight HIV
Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division. As a result, the cell changes in many ways, and its disease fighting ability is compromised. view more (2008-11-10)
First demonstration of new laser-driven accelerator technology
A team of UK scientists has used, for the first time, an extremely short-pulse laser to accelerate high-energy electrons over an incredibly short distance. Current accelerators can be hundreds of metres long, this is just a millimetre long. view more (2004-09-28)
New research contributes to defense of Earth's technologies
University of Leicester researchers have taken a step forward in helping to create a defence for earth's technologies -from the constant threat of space weather. view more (2009-06-03)
Beetles could prove a hit with the aircraft industry
A species of beetle, that squirts its predators with a high-pressure spray of boiling liquid, could provide the key to significant improvements in aircraft engine design. The bombardier beetle's unique natural combustion technique is being studied to see if it can be copied for use in the aircraft industry. Scientists studying the bombardier... view more...

Researchers discover new battleground for viruses and immune cells
Vaccines have led to many of the world's greatest public health triumphs, but many deadly viruses, such as HIV, still elude the best efforts of scientists to develop effective vaccines against them. view more (2008-02-07)
Research identifies first method for testing, assessing drug treatments for Chagas' disease
Chagas' disease is a tropical parasitic sickness that currently affects more than 16 million people, with a staggering 100 million at risk, largely in the tropical areas of South and Central America. And yet the main drug used to treat the disease is highly toxic and causes serious side effects. view more (2008-04-21)
ESA takes steps toward quantum communications
A team of European scientists has proved within an ESA study that the weird quantum effect called 'entanglement' remains intact over a distance of 144 kilometres. view more (2007-06-13)
Light turns liquid
LIGHT can be turned into a glowing stream of liquid that splits into droplets and splatters off surfaces just like water. The researchers who`ve worked out how to do this say "liquid light" would be the ideal lifeblood for optical computing, where chips send light around optical "circuits" to process data. Liquid light sounds like a... view more... (2002-07-03)
