Sandia weighs in on new definition for kilogram
The kilogram is losing weight and many international scientists, including some at Sandia National Laboratories, agree that it's time to redefine it.   view more (2008-02-29)

UK scientists working towards a redefinition of the kilogram
Scientists at the National Physical Laboratory (NPL) have released new research results that could affect how we measure a kilogram - the last SI unit based on a manufactured object.   view more (2007-11-02)

A better definition for the kilogram? Scientists propose a precise number of carbon atoms
How much is a kilogram? It turns out that nobody can say for sure, at least not in a way that won't change ever so slightly over time.   view more (2007-09-24)

DNA reveals hooded seals have wanderlust
Researchers have discovered a new fact about hooded seals, a mysterious 200 to 400 kilogram mammal that spends all but a few days each year in the ocean.   view more (2007-05-10)

New standard mass made with ISTC help
This program began three years ago and it involves scientists from eight countries. The task is immense. A new standard mass will be created with maximum possible precision on a modern level of development for world science and technology.   view more (2005-03-03)

Detergents, eye rinses and other products with an on/off switch
Researchers in Australia have developed a "switchable" detergent with a wide range of potential applications - from a laundry detergent that hardly needs a rinse cycle to a non-irritating eye rinse to increasing the amount of oil that companies can extract from a well.   view more (2007-08-22)

Human reproductive rates follow biological scaling rules
In nations with high per capita energy consumption, women have fewer children. This phenomenon is an unexpected consequence of the biological scaling relationship between metabolism and reproductive rate: larger species of mammals have higher metabolism but lower birth rates. In the April 2003... view more (2003-04-08)

Thermochemical process converts poultry litter into bio-oil
Foster Agblevor, associate professor of biological systems engineering, is leading the team of researchers in the College of Agriculture and Life Sciences at Virginia Tech developing transportable pyrolysis units that will convert poultry litter into bio-oil, providing an economical disposal system... view more (2007-08-20)

Sprats With Polonium
There are many radioactive elements in the world. For example, natural element polonium has 33 radioactive isotopes. Fortunately, only one isotope, 210Po, has a relatively long (138.4 days) half-life period. This isotope appears in the atmosphere as a result of radon decay, sinks to oceans and... view more (2002-07-19)

Dinosaurs Did Not Hatch Their Eggs
Dinosaurs laid eggs, but as dinosaurs were much heavier than birds, dinosaurs were unable to hatch the eggs. They would have simply broken them. The eggs at that time were alive, fragile, not fossilized and could not stand heavy pressure. Anyway, dinosaurs were reptiles and the reptiles do not sit... view more (2001-12-25)

'Bigger the baby, the better' axiom is incorrect
Dr Rachel Huxley, lead author of the paper and Acting Director of Nutrition and Lifestyle at The George Institute said, "Although there was support for a small association between birth weight and an individual's future risk of heart disease, the relationship is not as strong as earlier... view more (2007-05-18)

Canadian astronomers on hunt for meteor
Astronomers from The University of Western Ontario in London, Ontario, have captured rare video of a meteor falling to Earth.   view more (2008-03-10)

Maritime Fishery In Chukotka
Research by scientists from Kirov and Anadyr have found that the population of Chukotka revert to traditional ways of procuring food. Since the late 1990s, people have started to catch maritime animals more actively and go fishing, mushroom and berry-picking. For two or three thousand years,... view more (2003-09-05)

Baby satellites
ESA's second microsatellite, Proba-2, is under development for a launch early in 2006. Like Proba-1, in orbit since October 2001, Proba-2 will be no larger than a domestic washing machine and will weigh only 100 kilograms. The name Proba comes from the Project for On-board Autonomy. It blazes a... view more (2003-09-24)

People with type 2 diabetes can put fatty livers on a diet with moderate exercise
Weekly bouts of moderate aerobic exercise on a bike or treadmill, or a brisk walk, combined with some weightlifting, may cut down levels of fat in the liver by up to 40 percent in people with type 2 diabetes, a study by physical fitness experts at Johns Hopkins shows.   view more (2008-09-22)

Researchers note differences between people and animals on calorie restriction
Calorie restriction, a diet that is low in calories and high in nutrition, may not be as effective at extending life in people as it is in rodents, according to scientists at Washington University School of Medicine in St. Louis.   view more (2008-09-25)

Mercury contamination found in stranded Victorian dolphins
Monash University research into heavy metal contaminant levels in dolphins from Port Phillip Bay and the Gippsland Lakes has revealed high mercury levels may be a contributing factor to dolphin deaths.   view more (2008-06-10)

The Institite of Physics Celebrates 125th Anniversary
The campaign will demonstrate that physics is central and integral to modern life. The posters placed on 'Megarears' (the back of buses) and on bus interiors will depict bright images about physics topics which will be familiar to passengers. The accompanying strapline will read 'Thanks to Physics'.   view more (1999-02-10)

Liquid ventilation
The main problem that premature babies have is that their lungs are not well formed. In order to alleviate this situation, the Nautical School at the University of the Basque Country has developed a liquid respiration respirator.   view more (2006-03-29)

Crystal bells stay silent as physicists look for dark matter
Scientists of the Cryogenic Dark Matter Search experiment today announced that they have regained the lead in the worldwide race to find the particles that make up dark matter. The CDMS experiment, conducted a half-mile underground in a mine in Soudan, Minn., again sets the world's best constraints... view more (2008-02-26)

Harvesting Arctic algae
Microorganisms living in the depths of the oceans under conditions unbearable for humans utilize hot springs to produce their energy and substances. Some bacteria and algae feel right at home in the boiling waters of a geyser and others in acid ponds or salt waters. Still others populate glaciers... view more (2002-09-20)

The lung of the fuel cell
However environment-friendly fuel cells may be, like any other energy source their success on the market depends not only on their area of application but also, more particularly, on their price. A number of technological hurdles will have to be overcome before the various systems can be... view more (2003-04-04)

Bugs in the gut could play key role in understanding human disease and drug toxicity
Understanding how microbes in the gut interact with the body could lead scientists and doctors to new a understanding and novel treatments for diseases say scientists from Imperial College London and Astra Zeneca.   view more (2004-10-05)

Shield against assassin`s poison
Just a trace of ricin on the sharpened tip of an umbrella was enough to kill the Bulgarian dissident Georgi Markov, after an infamous attack on London`s Waterloo Bridge in 1978. Now a vaccine against this lethal toxin could soon be available - and it may be needed. "A big stash of ricin was found... view more (2002-09-11)
