UCLA physicists create world's smallest incandescent lamp
In an effort to explore the boundary between thermodynamics and quantum mechanics - two fundamental yet seemingly incompatible theories of physics - a team from the UCLA Department of Physics and Astronomy has created the world's smallest incandescent lamp. view more (2009-05-07)
Lifesaving lampposts
Plastic lamp-posts that cause less damage on collision could save hundreds of lives across Europe. In the UK alone, over 500 motorists are killed each year hitting roadside objects such as lampposts. The collapsing posts developed in this EUREKA project E! 2534 THERMOPOLE are able to absorb much of the force in a collision, saving the car driver... view more... (2003-11-05)
Lunar Reconnaissance Orbiter's LAMP shedding light on permanently shadowed regions of the Moon
NASA's Lunar Reconnaissance Orbiter (LRO), launched on June 18 of this year, has begun its extensive exploration of the lunar environment and will return more data about the Moon than any previous mission. view more (2009-09-18)
Are we trading energy conservation for toxic air emissions?
A team of Yale scientists has found that certain countries and some U.S. states stand to benefit from the use of compact fluorescent lighting more than others in the fight against global warming. Some places may even produce more mercury emissions by switching from incandescent light bulbs to compact fluorescent lighting. view more (2008-10-01)
Paint used by Dutch masters turns into rat poison
The painters Willem Kalf, Jan Davidsz. de Heem and Balthasar van der Ast are particularly famed for their bright yellow orpiment ("royal yellow"). The researchers have shown that light causes a chemical reaction in this yellow which separates the sulphur and the arsenic. The sulphur is released from the canvas as sulphur dioxide and hydrogen... view more... (1999-05-17)
Standards set for energy-conserving LED lighting
Scientists at the National Institute of Standards and Technology (NIST), in cooperation with national standards organizations, have taken the lead in developing the first two standards for solid-state lighting in the United States. view more (2008-06-30)
Voice-controlled electronics
Not only older and disabled people have trouble coping with the blessings of modern information technology. A lot of users have at some point ultimately faced exasperation in trying to understand printed user instructions for computers or answering machines, although the situation has meanwhile somewhat improved: Integrated electronic handbooks -... view more...

Transparent sinter alumina
The efficiency of halogen lamps could be increased by using pure sinter alumina instead of quartz glass. But the presently available types of this ceramic material diffuse the light. New and transparent ceramics for parts in almost any shape are highly pressure-resistant. Halogen plasma lamps emit a clearer and brighter light than conventional... view more... (2002-03-05)
Science in the making receives major Heritage Lottery funding
The Royal Institution of Great Britain (Ri), the home of science communication and scientific discovery, has been awarded a Stage One Pass for almost £5m from the Heritage Lottery Fund. The support will ensure that the Ri is able to exhibit the work of great scientists such as Sir Humphry Davy, Michael Faraday, James Dewar, William Bragg and... view more... (2004-03-11)
Engineers ride 'rogue' laser waves to build better light sources
A freak wave at sea is a terrifying sight. Seven stories tall, wildly unpredictable, and incredibly destructive, such waves have been known to emerge from calm waters and swallow ships whole. view more (2009-03-06)
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)
High efficiency flat light source invented
Scientists studying organic light-emitting devices (OLEDs) have made a critical leap from single-color displays to a highly efficient and long-lived natural light source. view more (2006-04-13)
WIRELESS EUROPE DIGEST: OCTOBER 2000 EDITION
Safety issues threaten the health of the mobile telephone industry Mixed messages abound regarding the potential health risks of mobile phones and masts, but one thing is clear – the mobile phone industry must address these issues if its own health is not to suffer. Much of the confusion has arisen because of the varying working methods for... view more... (2000-10-11)
Size of brain structure could signal vulnerability to anxiety disorders
The size of a particular structure in the brain may be associated with the ability to recover emotionally from traumatic events. A new study by researchers from Massachusetts General Hospital (MGH) finds that an area called the ventromedial prefrontal cortex is thicker in volunteers who appear better able to modify their anxious response to... view more...

Freeing light shines promise on energy-efficient lighting
The latest bright idea in energy-efficient lighting for homes and offices uses big science in nano-small packages to dim the future Edison's light bulb. view more (2008-07-16)
New coating is virtual black hole for reflections
Researchers have created an anti-reflective coating that allows light to travel through it, but lets almost none bounce off its surface. At least 10 times more effective than the coating on sunglasses or computer monitors, the material, which is made of silica nanorods, may be used to channel light into solar cells or allow more photons to surge... view more...

It's not all the parent's fault -- Delinquency in children now linked to biology
A unique study appearing in the June issue of Psychological Science, a journal of the Association for Psychological Science, shows that, in children, a highly reactive autonomic nervous system, which regulates our cardiovascular, digestive and respiratory functions, paired with a stressful family environment leads to increased instances of... view more...

Soft body fossils of extinct 'lamp shell' digitally reconstructed
A team of American and British scientists have identified and digitally reconstructed the first example of a fossilized brachiopod complete with its pedicle, the stalk attaching it to the sea floor, and its lophophore or feeding organ. view more (2005-08-18)
Sand dunes tell tale of volcanic devastation
University of Leicester scientists have made a unique discovery at an Atlantic island popular with British holidaymakers. They have uncovered giant sand dunes on Tenerife that tell a tale of terrifying destruction in ancient times, when fiery clouds swept right across the island, leaving very little in their wake. Volcanic islands - volcanoes... view more... (2004-05-06)
The biggest bug in gut discomfort
In spite of our long and painful relationship with Campylobacter jejuni, we are just starting to answer basic questions about the bug that is the leading cause of bacterial food-borne illness in the United States, and one of the most common causes of diarrhea worldwide. view more (2006-12-13)
