Brown Engineers Build a Better Battery - With Plastic
Brown University engineers have created a new battery that uses plastic, not metal, to conduct electrical current. The hybrid device marries the power of a capacitor with the storage capacity of a battery.   view more (2006-09-14)

Sell-by date "arbitrary" on some food packaging
New research on untreated green olives has found that products with a stated shelf-life of 2-3 years can be 'unacceptable' long before their sell-by date. The study, published in the Journal of the Science of Food and Agriculture, looked at the growing trend towards using polyethylene pouches which... view more (2004-04-06)

Mass flowering crops enhance pollinator densities at a landscape scale
The EU response to recent declines in pollinators and consequent loss of pollination services has been the inclusion of pollinator-friendly management in agri-environment schemes. These comprise the promotion of semi-natural habitats, such as set-aside and field margin strips. Yet, mass flowering... view more (2003-10-08)

New mouthwash helps with pain linked to head and neck cancer
Doctors in Italy are studying whether a new type of mouthwash will help alleviate pain for patients suffering from head and neck cancer who were treated with radiation therapy.   view more (2006-02-02)

WFU study finds that moths mimic sounds to survive
In a night sky filled with hungry bats, good-tasting moths increase their chances of survival by mimicking the sounds of their bad-tasting cousins, according to a new Wake Forest University study.   view more (2007-05-31)

Cancer could return unless stored ovarian tissue undergoes adequate testing before re-implantation
Cancer patients who have been successfully treated for their disease face the prospect of its return if stored ovarian (or testicular) tissue is transplanted back into their bodies without adequate checks, according to researchers at two university hospitals in Israel.   view more (2008-04-22)

Simple guide for suncreams will help users
Studies have shown that consumers apply much less sunscreen than is required to achieve the sun protection factor (SPF) stated on the product. In this week’s BMJ, researchers suggest a simple guide to ensure that people are protected according to their expectations.   view more (2002-06-19)

The ink is mightier than the pen - against forgery
Inks which cannot be photocopied - to confound bank-note forgers - are exciting printers of most of the world`s major currencies. A team from colour chemistry, led by Professor David Lewis and Dr Long Lin, has created an ink which changes colour when copied or scanned, to prevent forgers colour... view more (2002-06-07)

Compound removes radioactive material from power plant waste
Strontium 90 is a common radioactive by-product of fission in nuclear power plants. When extracted from the reactor along with other isotopes, a mixture is created made up of the radioactive material and inert ions like sodium and calcium.   view more (2008-03-13)

Hind wings help butterflies make swift turns to evade predators, study finds
New tires allow race cars to take tight turns at high speeds. Hind wings give moths and butterflies similar advantages: They are not necessary for basic flight but help these creatures take tight turns to evade predators.   view more (2009-01-09)

Successes in frozen ovarian tissue technology may offer hope to women being treated for cancer
Berlin, Germany: Doctors in Denmark have succeeded in producing a two-cell embryo after ovarian tissue was removed, frozen, and then thawed and replaced two years later. It is believed that this is the first time a European group has succeeded in creating an embryo in this way. Dr Claus Yding... view more (2004-06-29)

Threatened bumble bee populations studied in Southampton

Licorice extract provides new treatment option for canker sores
What common oral condition appears as shallow ulcers of different sizes, affects one in five Americans, can be caused by food allergies and hormonal changes, and also can cause severe mouth pain?   view more (2008-05-23)

Prompting men to have syphilis tests
An innovative social marketing campaign called "Healthy Penis," which used humorous cartoon strips to encourage gay and bisexual men in San Francisco to get checked for syphilis, was associated with an increase in syphilis tests, according to evaluations published in PLoS Medicine.   view more (2006-12-26)

Black tea soothes away stress
Daily cups of tea can help you recover more quickly from the stresses of everyday life, according to a new study by UCL (University College London) researchers. New scientific evidence shows that black tea has an effect on stress hormone levels in the body.   view more (2006-10-05)

Reach out and touch an oscillator: Cornell researchers find a new way to read nanoscale vibrations
Nanomechanical oscillators — tiny strips of vibrating silicon only a few hundred atoms thick — are the subject of extensive study by nanotechnology researchers. They could someday replace bulky quartz crystals in electronic circuits or be used to detect and identify bacteria and viruses.   view more (2007-03-27)

Brown Chemists Explain the Origin of Soil-Scented Geosmin
Brown University chemists have found the origins of an odor - the sweet smell of fresh dirt. In Nature Chemical Biology, the Brown team shows that the protein that makes geosmin - source of the good earth scent - has two similar but distinct halves, each playing a critical role in making this... view more (2007-09-17)

K-State professor's research suggests that cigarettes' power may not be in nicotine itself
There may be a very good reason why coffee and cigarettes often seem to go hand in hand.   view more (2008-09-04)

Size matters in language research
How do you measure your knowledge of a language? Understanding grammar was seen in the past as the vital factor. Now, whether it is your mother tongue or a second language, the words you use are seen as the most important aspect in making a language come alive. But how easy is it to measure the... view more (2004-01-27)

Forming super-Earths by ultraviolet stripping
A new explanation for forming "super-Earths" suggests that they are more likely to be found orbiting red dwarf stars—the most abundant type of star—than gas giant planets like Jupiter and Saturn.   view more (2006-06-08)

BEER AS A REMEDY FOR DYSBACTERIOSIS
A scientist from Novosibirsk, Vladimir Baibakov has developed a recipe of the so-called bifidobeer - the beer which contains bifidobacteria similarly to bifidokefir. But why should beer contain bifidobacteria? Is not it too much of a good thing? Not at all. It appears that bifidobacteria contained... view more (2002-08-09)

'Nanonet' circuits closer to making flexible electronics reality
Researchers have overcome a major obstacle in producing transistors from networks of carbon nanotubes, a technology that could make it possible to print circuits on plastic sheets for applications including flexible displays and an electronic skin to cover an entire aircraft to monitor crack... view more (2008-07-24)

Silicon Thin-Film Solar Cells Gaining In Efficiency
An important goal of modern energy research is to directly convert sunlight into electricity at low cost. Silicon thin-film solar cells promise comparatively lower costs than conventional solar cells. However, to become a mass product of the future, the efficiencies of large-area modules must climb... view more (2002-08-08)
