Cornell researchers develop virus-size 'nanolamps' that could aid use of flexible electronic devices as sensors
To help light up the nanoworld, a Cornell interdisciplinary team of researchers has produced microscopic "nanolamps" — light-emitting nanofibers about the size of a virus or the tiniest of bacteria.   view more (2007-04-12)

NASA predicts nongreen plants on other planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems.   view more (2007-04-11)

Structural basis for photoswitching in fluorescent proteins brought into focus
University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.   view more (2007-04-11)

Networking around the clock
A Brandeis University study published in Cell this week shows for the first time experimentally that the circadian cells in fruit flies function as a network that enables the insects to adapt their behavior according to seasonal changes.   view more (2007-04-09)

Secondhand smoke proves to be no 'joke' on oral health
A study published in this month's issue of the Journal of Periodontology found that subjects with periodontitis who were exposed to secondhand smoke were more likely to develop bone loss, the number one cause of tooth loss.   view more (2007-04-04)

Laser Goes Tubing for Faster Body-Fluid Tests
University of Rochester researchers announce in the current issue of Applied Optics a technique that in 60 seconds or less measures multiple chemicals in body fluids, using a laser, white light, and a reflective tube.   view more (2007-04-03)

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)

Examination of radiation left from birth of universe could alter theories
Using relic radiation from the birth of the universe, astrophysicists at the University of Illinois have proposed a new way of measuring the fine-structure constant in the past, and comparing it with today.   view more (2007-04-03)

Titanium dioxide — It slices, it dices ...
Chemists from the National Institute of Standards and Technology (NIST) and Arizona State University have proposed an elegantly simple technique for cleaving proteins into convenient pieces for analysis.   view more (2007-04-02)

Making mice with enhanced color vision
Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated.   view more (2007-03-23)

Smoking associated with aging of nonfacial skin
A history of smoking may be associated with a higher degree of aging in skin not regularly exposed to light, such as that of the upper inner arm.   view more (2007-03-20)

Robotic telescope unravels mystery of cosmic blasts
Scientists have used the world's largest robotic telescope to make the earliest-ever measurement of the optical polarisation* of a Gamma Ray Burst (GRB) just 203 seconds after the start of the cosmic explosion. This finding, which provides new insight into GRB physics, is published in Science today... view more (2007-03-19)

Star Family Seen Through Dusty Fog
Images made with ESO's New Technology Telescope at La Silla by a team of German astronomers reveal a rich circular cluster of stars in the inner parts of our Galaxy. Located 30,000 light-years away, this previously unknown closely-packed group of about 100,000 stars is most likely a new globular... view more (2007-03-14)

A short walk helps smokers quit
Smokers should do short bouts of exercise to help them resist the temptation to light up, say experts at the University of Exeter.   view more (2007-03-14)

A Single-Photon Server with Just One Atom
Every time you switch on a light bulb, 10 to the power of 15 (a million times a billion) visible photons, the elementary particles of light, are illuminating the room in every second. If that is too many for you, light a candle.   view more (2007-03-13)

New report: Explosive growth changes salmon industry
A new report, the first to take a comprehensive look at market competition between wild and farmed salmon, sheds new light on the contentious and complex issues surrounding farmed and wild salmon.   view more (2007-03-08)

Photodynamic therapy as alternative therapy for periodontal diseases may be beneficial
Photodynamic therapy (PDT) may be an effective way to treat the bacteria associated with periodontal diseases, and could provide a better option than antibiotics or other mechanical methods for treating periodontal diseases, according to a new study published in the March issue of the Journal of... view more (2007-03-07)

Light-activated compound silences nerves, may one day help epileptics
Brain activity has been compared to a light bulb turning on in the head. Scientists at Washington University School of Medicine in St. Louis have reversed this notion, creating a drug that stops brain activity when a light shines on it.   view more (2007-03-07)

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... view more (2007-03-05)

First direct electric link between neurons and light-sensitive nanoparticle films created
The world's first direct electrical link between nerve cells and photovoltaic nanoparticle films has been achieved by researchers at the University of Texas Medical Branch at Galveston (UTMB) and the University of Michigan.   view more (2007-02-28)

NASA Scientists Detect Spectrum of Planets Orbiting Other Stars
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth.   view more (2007-02-23)

LSU professor resolves Einstein's twin paradox
Subhash Kak, Delaune Distinguished Professor of Electrical and Computer Engineering at LSU, recently resolved the twin paradox, known as one of the most enduring puzzles of modern-day physics.   view more (2007-02-15)

Researchers create new super-thin laser mirror
Engineers at the University of California, Berkeley, have created a new high-performance mirror that could dramatically improve the design and efficiency of the next generation of devices relying upon laser optics, including high-definition DVD players, computer circuits and laser printers.   view more (2007-02-14)

Supernovae-Cosmic Lighthouses
Supernovae stand out in the sky like cosmic lighthouses. Scientists at the Max Planck Institute for Astrophysics and at the National Astronomical Institute of Italy have now found a way to use these cosmic beacons to measure distances in space more accurately.   view more (2007-02-12)

In tiny supercooled clouds, physicists exchange light and matter
Physicists have for the first time stopped and extinguished a light pulse in one part of space and then revived it in a completely separate location.   view more (2007-02-08)
