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. 

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.).

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. 

A new class of fuel cells based on a newly discovered polymer-based material could bridge the gap between the operating temperature ranges of two existing types of polymer fuel cells, a breakthrough with the potential to accelerate the commercialization of low-cost fuel cells for automotive and stationary applications.

A Los Alamos National Laboratory team, in collaboration with Yoong-Kee Choe at the National Institute of Advanced Industrial Science and Technology in Japan and Cy Fujimoto of Sandia National Laboratories, has discovered that fuel cells made from phosphate-quaternary ammonium ion-pair can be operated between 80°C and 200°C with and without water, enhancing the fuel cells usability in a range of conditions. The research is published in the journal Nature Energy.

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.
