'Invisible' bacteria dupe the human immune system
Scientists at the University of York have characterised an important new step in the mechanism used by bacteria to evade our immune system. view more (2008-02-20)
Sound nutrition for children is an unmet human right
The three largest nutrition crises in the world today are in West Africa, Niger and Ethiopia and, contrary to popular perception, they are not the result of conflict or natural disaster. view more (2006-02-10)
Where Have All the Butterflies Gone?
Cold, wet conditions early in the year mean that 2006 is shaping up as the worst year for California's butterflies in almost four decades. view more (2006-05-09)
Scientists step closer to realising invisible technology
A unique computer model designed by a mathematician at the University of Liverpool has shown that it is possible to make objects, such as aeroplanes and submarines, appear invisible at close range. view more (2007-05-04)
'Conversation stoppers' fight deadly bacterial infections
Bacterial infections are becoming more deadly worldwide due to increased resistance to antibiotics. Now, chemists at the University of Wisconsin-Madison have developed a powerful strategy to fight these deadly infections: Instead of killing the bacteria directly, the scientists designed a group of compounds that can block the chemical signals that... view more...

Universe's oldest objects emerge from the background
The deepest reaches of space are permeated by a cloak of infrared radiation, an uneven energy swath generated by long-dead objects from the early universe. view more (2006-12-20)
Theoretical blueprint for invisibility cloak reported
Using a new design theory, researchers at Duke University's Pratt School of Engineering and Imperial College London have developed the blueprint for an invisibility cloak. view more (2006-05-26)
Mars and Venus are surprisingly similar
Using two ESA spacecraft, planetary scientists are watching the atmospheres of Mars and Venus being stripped away into space. The simultaneous observations by Mars Express and Venus Express give scientists the data they need to investigate the evolution of the two planets' atmospheres. view more (2008-03-06)
Next generation cloaking device demonstrated
A device that can bestow invisibility to an object by "cloaking" it from visual light is closer to reality. After being the first to demonstrate the feasibility of such a device by constructing a prototype in 2006, a team of Duke University engineers has produced a new type of cloaking device, which is significantly more sophisticated at... view more...

Metamaterials four to work for visible light
For the first time ever, researchers at the U.S. Department of Energy's Ames Laboratory have developed a material with a negative refractive index for visible light. view more (2007-01-05)
The Mathematics of Cloaking
The theorists who first created the mathematics that describe the behavior of the recently announced "invisibility cloak" have revealed a new analysis that may extend the current cloak's powers, enabling it to hide even actively radiating objects like a flashlight or cell phone. view more (2006-12-27)
'Electromagnetic Wormhole' Possible with Invisibility Technology
The team of mathematicians that first created the mathematics behind the "invisibility cloak" announced by physicists last October has now shown that the same technology could be used to generate an "electromagnetic wormhole." view more (2007-10-15)
Scientists use nanomaterials to localize and control drug delivery
Using nanotechnology, scientists from UCLA and Northwestern University have developed a localized and controlled drug delivery method that is invisible to the immune system, a discovery that could provide newer and more effective treatments for cancer and other diseases. view more (2008-01-23)
Engineers create 'optical cloaking' design for invisibility
Researchers using nanotechnology have taken a step toward creating an "optical cloaking" device that could render objects invisible by guiding light around anything placed inside this "cloak." view more (2007-04-03)
Tumor wizardry wards off attacks from the immune system
Like the fictional wizard Harry Potter, some cancerous tumors seem capable of wrapping themselves in an invisibility cloak. Researchers at Washington University School of Medicine in St. Louis have found that pancreatic tumors hide from the body's immune surveillance by surrounding themselves with cells that make it hard for the immune system to... view more...

'Invisibility cloaks' could break sound barriers
Contrary to earlier predictions, Duke University engineers have found that a three-dimensional sound cloak is possible, at least in theory. view more (2008-01-10)
UV light improving chances of fighting cancer
Scientists at Newcastle University have developed a cancer fighting technology which uses UV light to activate antibodies which very specifically attack tumours. view more (2007-10-30)
The Pied Piper of Fish
Fishy noises could be the answer for improved reef fisheries management according to an international team of researchers. Some juvenile coral reef fish are attracted by sounds they would have heard while they were in the egg. By using these sounds, the fish can be led to artificial reefs where they will start new colonies. It may be possible in... view more... (2003-06-03)
Genetic differences in clover make one type toxic
That clover necklace you make for your child could well be a ring of poison. That's because some clovers have evolved genes that help the plant produce cyanide - to protect itself against little herbivores, such as snails, slugs and voles, that eat clover. view more (2007-10-02)
Steps towards warship invisibility
Naval warships might look like all-powerful vessels but they are also highly vulnerable to being spotted by the enemy. view more (2008-03-03)
