Measurement of stellar age from uranium decay
For the first time, an international team (led by Roger Cayrel, from Paris Observatory), could measure one uranium line in absorption in a star. This observation has several important implications. It is a great discovery, obtained thanks to the high resolution spectrograph UVES, assembled on one of the 8m-diameter telescopes of the Very Large... view more... (2001-02-05)

Sunflowers that love heavy metal
Sunflowers take up uranium twice or even three times better than their maize and soybean counterparts, making them a top 'clean crop' for removing toxic metals from the environment. Scientists at the Centre for Pesticides and Environmental Research, Yugoslavia, studied growth and uranium uptake in sunflower, soybean and maize crops. Sunflowers... view more... (2001-04-01)

Solitons Seen in a Solid
Isolated vibrations within a three-dimensional solid have been observed for the first time by researchers in the U.S. and Germany. The work could help explain how metals such as uranium behave when bent, compressed or heated.   view more (2006-04-07)

Ape-man skeleton is 2.2 million years old, say scientists
Scientists at the University of Liverpool have dated an ape-man skeleton at 2.2 million years old suggesting that it may not have been part of the ancestral tree leading to humankind as originally thought.   view more (2006-12-13)

How Old is the Universe?
Most astronomers would agree that the age of the Universe - the time elapsed since the "Big Bang" - is one of the "holy grails of cosmology". Despite great efforts during recent years, the various estimates of this basic number have resulted in rather diverse values. When derived from current cosmological models, it depends on a number of... view more... (2001-02-06)

Hydrogen protects nuclear fuel in final storage
When Sweden's spent nuclear fuel is to be permanently stored, it will be protected by three different barriers. Even if all three barriers are damaged, the nuclear fuel will not dissolve into the groundwater, according to a new doctoral dissertation from Chalmers University of Technology in Sweden.   view more (2009-04-27)

Scientist refines cosmic clock to determine age of Milky Way
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods.   view more (2005-06-30)

Measurements link magma melting rate to tectonic plate subduction rate
Determining the origin and rate of magma production in subduction zone volcanoes is essential to understanding the formation of continental crust and the recycling of subducted materials back into Earth's mantle.   view more (2007-11-09)

Nuclear cannibals
Nuclear energy production must increase by more than 10 percent each year from 2010 to 2050 to meet all future energy demands and replace fossil fuels, but this is an unsustainable prospect.   view more (2008-03-05)

Depleted uranium shells make a deadly playground
EMBARGOED UNTIL WEDNESDAY 24 JULY 2001 19:00 BST UK CONTACT - Claire Bowles, New Scientist Press Office, London: Tel: +44(0)20 7331 2751 or email claire.bowles@rbi.co.uk SOIL in the Gulf and the Balkans that`s contaminated with debris from spent depleted uranium weapons presents far too high a risk to local children, an Italian study confirms.... view more...

Purdue engineers create safer, more efficient nuclear fuel, model its performance
Purdue University nuclear engineers have developed an advanced nuclear fuel that could save millions of dollars annually by lasting longer and burning more efficiently than conventional fuels, and researchers also have created a mathematical model to further develop the technology.   view more (2005-09-29)

Turning a nuclear spotlight on illegal weapons material
Researchers at the National Institute of Standards and Technology (NIST) and Oak Ridge National Laboratory (ORNL) have demonstrated that they can cheaply, quickly and accurately identify even subnanogram amounts of weapon-grade plutonium and uranium.   view more (2006-10-30)

Hotspots of mercury contamination identified in eastern North America
A US and Canadian research team surveying mercury contamination in fish and birds in the northeastern United States and southeastern Canada has identified five "hotspots" where concentrations of the element exceed those established for human or wildlife health.   view more (2007-01-03)

Did Rats Spread SARS In Amoy Gardens? (p 570)
A hypothesis in this week's issue of THE LANCET proposes that roof rats could have been responsible for the spread of the severe acute respiratory syndrome (SARS) outbreak in Hong Kong's Amoy Gardens apartment block where over 300 people were infected with the SARS virus earlier this year. Stephen Ng from Columbia University School of Public... view more... (2003-08-13)

Food safety begins as vegetables grow
Monitoring vegetables while they are growing is crucial in the prevention of contamination of fresh produce with harmful bacteria such as E. coli and Salmonella, say plant pathologists who are members of The American Phytopathological Society (APS).   view more (2007-06-12)

Deadly dose: Rensselaer heparin expert helps uncover source of lethal contamination
The mysterious death of patients around the world following a routine dosage of the common blood thinner, heparin, sent researchers on a frantic search to uncover what could make the standard drug so toxic.   view more (2008-04-28)

The Azov Sea: Radiation Recedes
Radioactive contamination of the Azov Sea has reached the level which existed before 1986 when the wreck of the Chernobyl nuclear power plant occurred. However, scientists state that regular check-ups of radio-ecological situation in the sea should be continued as the sea can be contaminated for the second time and this can happen even without... view more...

Unpasteurized milk poses health risks without benefits
With disease outbreaks linked to unpasteurized milk rising in the United States, a review published in the January 1, 2009 issue of Clinical Infectious Diseases examines the dangers of drinking raw milk.   view more (2008-12-17)

Scientists observe solitary vibrations in uranium
Los Alamos scientists, working with collaborators from around the world, recently observed experimental evidence of solitary vibrations (solitons) in a solid.   view more (2006-03-31)

Sheffield scientists light up bacteria
Researchers from the University of Sheffield have received joint funding from the Engineering and Physical Science Research Council (EPSRC) and the Ministry of Defence (MoD) to develop an innovative sensor to detect bacteria.   view more (2007-03-13)
