Most academics don't like competition but in the field of artificial intelligence, everyone wants to square off against the best in their discipline.

In June, the International Planning Competition held every two years will take place in  New Hampshire. It  is divided into four categories, the most significant of which is considered the “deterministic track”. This is for programs designed to eliminate any element of chance from automated planning in a wide range of fields, such as logistics, robot manipulation, satellite movement and transport. 

Mercury levels in excess of U.S. Environmental Protection Agency health thresholds for potential impacts to fish, birds, and humans have been detected in fish in some of the most remote national park lakes and streams in the western United States and Alaska.

 Mercury is harmful to human and wildlife health. It arises from natural sources, such as volcanic eruptions, and from human sources such as burning fossil fuels in power plants. Mercury is distributed at local or regional scales as a result of current and historic mining activities. Human activities have increased levels of atmospheric mercury at least three fold during the past 150 years.  

DURHAM, N.C. – Within each strand of DNA lies the blueprint for building an organism, along with the keys to its evolution and survival. These genetic instructions can give valuable insight into why pathogens like Cryptococcus neoformans -- a fungus responsible for a million cases of pneumonia and meningitis every year -- are so malleable and dangerous.

A groundbreaking study published in PLOS ONE by Prof. Iris Berent of Northeastern University and researchers at Harvard Medical School shows the brains of individual speakers are sensitive to language universals. Syllables that are frequent across languages are recognized more readily than infrequent syllables. Simply put, this study shows that language universals are hardwired in the human brain.

The tropical disease malaria is caused by the Plasmodium parasite. For its survival and propagation, Plasmodium requires a protein called actin. Scientists of the Helmholtz Centre for Infection Research (HZI) in Germany used high-resolution structural biology methods to investigate the different versions of this protein in the parasite in high detail. Their results may in the future contribute to the development of tailor-made drugs against malaria–a disease that causes more than half a million deaths per year.

Sulfur left over from refining fossil fuels can be transformed into cheap, lightweight, plastic lenses for infrared devices, including night-vision goggles, a University of Arizona-led international team has found.

The team successfully took thermal images of a person through a piece of the new plastic. By contrast, taking a picture taken through the plastic often used for ordinary lenses does not show a person's body heat.

"We have for the first time a polymer material that can be used for quality thermal imaging – and that's a big deal," said senior co-author Jeffrey Pyun, whose lab at the UA developed the plastic. "The industry has wanted this for decades."
