Light activated anticancer drug targeted to DNA using cisplatin like sub-units
One of the most effective chemotherapy drugs against cancer is cisplatin because it attaches to cancer DNA and disrupts repair.   view more (2006-03-27)

The Role Of Phytochromes In Bacteria Revealed
A research team jointly involving the IRD, the CEA and the CNRS has very recently found phytochromes in a strain of nitrogen-fixing bacterium, Bradyrhizobium (1), symbiont on certain tropical leguminous plants (the Aeschynomene). Techniques of molecular biology, biophysics and biochemistry revealed... view more (2002-05-13)

Air pollution from ships - a serious threat
Emissions from ships may bring as much nitrogen oxide to the atmosphere as the total amount of emissions coming from the USA. International shipping along the Norwegian coast and in the Northern Atlantic Ocean contributes largely to the formation of ground-level ozone and acidification of the... view more (2004-03-30)

Numerical simulations of nutrient transport changes in Honghu Lake Basin
The research by Gui Feng & Yu Ge showed the relative role of natural, climate-induced changes versus human-related activities in nutrient transportation changed over time.   view more (2008-08-20)

Abertay researchers in clover to unearth destructive bug
Scots scientists are playing a key role in a major new research effort which could save Britain's farmers millions of pounds a year through reductions in fertiliser and pesticide use. Biotechnology experts at the University of Abertay Dundee, in partnership with two organisations in England, have... view more (2002-04-04)

Researchers put the bite on mosquitoes
Few things sting like a mosquito's bite--especially if that bite carries a disease such as malaria, yellow fever, Dengue fever or West Nile virus. But if researchers from The University of Arizona in Tucson have their way, one day mosquito bites may prove deadly to the mosquitoes as well.   view more (2008-01-17)

Isotope analysis reveals foraging area dichotomy for Atlantic leatherback turtles
The beaches of French Guiana constitute a major reproduction site for leatherback turtles. This sea turtle, although a protected species, is threatened by human activity: it ingests plastics, get accidentally caught in fishing nets, sees its egg-laying sites destroyed and its adults hunted... view more (2008-03-26)

Winds trigger increases in ozone destroying gases in upper stratosphere
A surprising new University of Colorado at Boulder study indicates winds circling high above the far Northern Hemisphere have a much greater impact on upper stratospheric ozone levels than scientists had thought.   view more (2006-09-29)

Insects take a bigger bite out of plants in a higher CO2 world
Atmospheric carbon dioxide levels are rising at an alarming rate, and new research indicates that soybean plant defenses go down as CO2 goes up. Elevated CO2 impairs a key component of the plant's defenses against leaf-eating insects, according to the report.   view more (2008-03-25)

First buoy to monitor ocean acidification launched
The first buoy to monitor ocean acidification has been launched in the Gulf of Alaska. Attached to the 10-foot-diameter buoy are sensors to measure climate indicators.   view more (2007-06-13)

Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity.   view more (2008-04-25)

Pesticides Persist in Ground Water
Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations.   view more (2008-07-02)

Economical and cleaner cars with lean-burn catalytic converter
Dutch researcher Karen Scholz has taken a careful look at the properties of a new type of catalytic converter found in cars.   view more (2007-07-13)

Setting stars reveal planetary secrets
Watching the stars set from the surface of the Earth may be a romantic pastime but when a spacecraft does it from orbit, it can reveal hidden details about a planet's atmosphere.   view more (2007-11-06)

Experiment Demonstrates 110 Years of Sustainable Agriculture
A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods.    view more (2008-09-30)

Atmospheric chemistry - air quality and climate
Air quality has improved dramatically over the past 50 years. Professor Mike Pilling, Head of Physical Chemistry at the University of Leeds, will reveal the latest about air quality research at the Festival of Science today.   view more (2004-09-06)

Chemists forge a new form of iron
An international team of chemists has discovered a new and unexpected form of iron, a finding that adds to the fundamental understanding of an element that is among the most abundant on Earth and that, in nature, is an essential catalyst for life.   view more (2006-06-02)

Eating cured meats frequently can lead to lower lung function and potential COPD
Frequent consumption of cured meats results in lower lung function test scores and increases the odds of developing chronic obstructive pulmonary disease (COPD), according to a large cross-sectional survey of adults in the U.S.   view more (2007-04-16)

Berkeley Lab's Ultraclean Combustion Technology For Electricity Generation Fires Up in Hydrogen Tests
An experimental gas turbine simulator equipped with an ultralow-emissions combustion technology called LSI has been tested successfully using pure hydrogen as a fuel - a milestone that indicates a potential to help eliminate millions of tons of carbon dioxide and thousands of tons of NOx from power... view more (2007-08-03)

Scientists levitate diamond, lead and platinum
Scientists at The University of Nottingham have successfully levitated diamond and some of the heaviest elements, including lead and platinum.   view more (2005-05-11)

Mandate for biofuels production requires science-based policy and global perspective
In his State of the Union Address on January 23, 2007, President Bush stated that, in order to substantially lower foreign oil imports, "We must increase the supply of alternative fuels, by setting a mandatory fuels standard to require 35 billion gallons of renewable and alternative fuels in... view more (2008-10-03)

Argonne breakthrough may revolutionize ethylene production
A new environmentally friendly technology created by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory may revolutionize the production of the world's most commonly produced organic compound, ethylene.   view more (2008-02-06)

UK Astronomers Survey Galactic Graveyard
An unprecedented source of planetary nebulae, the disk-like relics of elderly, dying stars, has been discovered in the southern part of our Milky Way galaxy. With about 1000 planetary nebulae found so far and many more still to be discovered, the number of aged stars in their death throes revealed... view more (2002-04-07)

Single spinning nuclei in diamond offer a stable quantum computing building block
Surmounting several distinct hurdles to quantum computing, physicists at Harvard University have found that individual carbon-13 atoms in a diamond lattice can be manipulated with extraordinary precision to create stable quantum mechanical memory and a small quantum processor, also known as a... view more (2007-06-01)

Nitrous Oxide Emissions Respond Differently to No-Till Depending on the Soil Type
The practice of no-till has increased considerably during the past 20 yr. The absence of tillage coupled with the accumulation of crop residues at the soil surface modifies several soil properties but also influence nitrogen dynamics.   view more (2008-10-23)
