Following the phase out of methyl bromide, scientists continue to explore effective, viable, and more sustainable options for vegetable crop production. Among nonchemical alternatives, anaerobic soil disinfestation (ASD) is considered to be one of the most promising methods. ASD has been determined to be effective with a range of crops and environments against several soilborne fungal and bacterial plant diseases, plant-parasitic nematodes, and weeds.

New electrical energy storage material shows its power
A powerful new material developed by Northwestern University chemist William Dichtel and his research team could one day speed up the charging process of electric cars and help increase their driving range.
An electric car currently relies on a complex interplay of both batteries and supercapacitors to provide the energy it needs to go places, but that could change.
"Our material combines the best of both worlds -- the ability to store large amounts of electrical energy or charge, like a battery, and the ability to charge and discharge rapidly, like a supercapacitor," said Dichtel, a pioneer in the young research field of covalent organic frameworks (COFs).
Smoke Waves Are the Next Climate Change Problem
In the hills near Los Angeles, the Blue Cut Fire just ripped through 36,000 acres, taking dozens of homes along with it, spurring a major evacuation, and even requiring temporary highway closures. But the merciless flames of the Blue Cut Fire almost pale in comparison with the flood of wildfires across the Golden State, and the West at large, in an era when the wildfire season is growing longer and more aggressive every year. Climate change is the reason why, and researchers are discovering that the cost of wildfires may be bigger than we imagined: They’re tracking deadly “smoke waves” that sweep the landscape, causing serious respiratory health problems.
How Elephant Seals Are Helping Scientists Study Climate Change
A group of southern elephant seals is helping scientists monitorhow climate change is impacting Antarctica by tracking water temperature, depth, and salinity as they swim and dive around the frozen continent.
El más antiguo habitante conocido de Europa
Un pino de los Balcanes (Pinus heldreichii) que crece en las tierras altas del norte de Grecia ha sido datado con más de 1075 años de antigüedad. Esto hace que sea actualmente el árbol vivo más antiguo conocido en Europa. El pino milenario fue descubierto por científicos de la Universidad de Estocolmo (Suecia), la Universidad de Mainz (Alemania) y la Universidad de Arizona (EE.UU.).
Selecting the right house plant could improve indoor air
Indoor air pollution is an important environmental threat to human health, leading to symptoms of "sick building syndrome." But researchers report that surrounding oneself with certain house plants could combat the potentially harmful effects of volatile organic compounds (VOCs), a main category of these pollutants. Interestingly, they found that certain plants are better at removing particular harmful compounds from the air, suggesting that, with the right plant, indoor air could become cleaner and safer.
The researchers are presenting their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world's largest scientific society, is holding the meeting here through Thursday. It features more than 9,000 presentations on a wide range of science topics. A brand-new animation on the research is available at http://bit.ly/ACSindoorairpollution.
"Buildings, whether new or old, can have high levels of VOCs in them, sometimes so high that you can smell them," says Vadoud Niri, Ph.D., leader of the study.
