Untangling Brazil's controversial new forest code
Brazil's new Forest Code has few admirers. A study, co-authored by Woods Hole Research Center scientists Michael Coe, Marcia Macedo and Brazilian colleagues, published this week in Science, seeks to clarify the new law.

Oldest pterodactyloid species discovered, named by international team of researchers
An international research team, including a George Washington University professor, has discovered and named the earliest and most primitive pterodactyloid -- a group of flying reptiles that would go on to become the largest known flying creatures to have ever existed -- and established they flew above the earth some 163 million years ago, longer than previously known.

Researchers create comprehensive map of human B cell development
A Columbia and Stanford team describes a new method for mapping cellular development at the single cell level. By combining emerging technologies with a new, advanced computational algorithm, they created the most comprehensive map ever made of human B cell development. The approach will improve the ability to investigate development in cells of all types, help identify rare aberrations that lead to disease, and guide the next generation of research in regenerative medicine.

Economics = MC2 -- A portrait of the modern physics startup
In recent decades, many large high-tech companies have eliminated in-house research programs, turning instead to startup companies as their primary source of breakthrough innovations. AIP has released a new report on physics startups, based on interviews with 140 physicists and other professionals at some 91 startup companies in 14 states, companies which are engaged in making medical devices, manufacturing tools, nanotechnology, lasers and optical devices, renewable energy technologies and other products.

Scientists identify source of mysterious sound in the Southern Ocean
Scientists have conclusive evidence that the source of a unique rhythmic sound, recorded for decades in the Southern Ocean and called the 'bio-duck,' is the Antarctic minke whale (Balaenoptera bonaerensis). First described and named by submarine personnel in the 1960s who thought it sounded like a duck, the bio-duck sound has been recorded at various locations in the Southern Ocean, but its source has remained a mystery, until now.

Best practices in communication for the animal world
Effective communication is not just about the signaler, according to the study, the receiver also needs to assess the signaler efficiently. For instance, one of the most effective strategies from the perspective of female birds is assessing groups of males called leks, where females can assess multiple males in a short period of time.

Connecticut River watershed study will assess impacts of extreme rain events
A team of Yale researchers will lead a five-year, $3 million study to determine whether an increase in extreme rain events is affecting the transport of dissolved organic matter through the Connecticut River watershed, a phenomenon they say could alter the chemical composition and water quality of the watershed and Long Island Sound. The grant is funded by the National Science Foundation's MacroSystems Biology program.

Carnegie Mellon system lets iPad users explore data with their fingers
Spreadsheets may have been the original killer app for personal computers, but data tables don't play to the strengths of multi-touch devices such as tablets. So researchers at Carnegie Mellon University have developed a visualization approach that allows people to explore complex data with their fingers. Called Kinetica, the proof-of-concept system for the Apple iPad converts tabular data, such as Excel spreadsheets, into colored spheres that respond to touch.

Cougars' diverse diet helped them survive the Pleistocene mass extinction
Cougars may have survived the mass extinction that took place about 12,000 years ago because they were not particular about what they ate, unlike their more finicky cousins the saber-tooth cat and American lion who perished, according a new analysis of the microscopic wear marks on the teeth of fossil cougars, saber-tooth cats and American lions.

Scientists successfully use krypton to accurately date ancient Antarctic ice
A team of scientists has successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating -- a new technique that may allow them to locate and date ice that is more than a million years old. This will allow them to reconstruct the climate much farther back into Earth's history and potentially understand the mechanisms that have triggered the planet to shift into and out of ice ages.
