Studies affirm crabs killing Northeast saltmarshes
Two newly published studies by a team of Brown University researchers provide ample new evidence that the reason coastal saltmarshes are dying from Long Island to Cape Cod is that hungry crabs, left unchecked by a lack of predators, are eating the cordgrass.

Urbanization, higher temperatures can influence butterfly emergence patterns
An international team of researchers has found that a subset of common butterfly species are emerging later than usual in urban areas located in warmer regions, raising questions about how the insects respond to significant increases in temperature.

R.I. nitrogen cycle differs in bay and sound
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it's a major factor just a little farther out into Rhode Island Sound. Scientists traced that to differences between bay and sound sediments, but that raises new questions about what's going on in the Bay to account for those.

Brazilian agricultural policy could cut global greenhouse gas emissions
Brazil may be able to curb up to 26 percent of global greenhouse gas emissions from deforestation by encouraging the intensification of its cattle production, according to a new study from researchers at the International Institute for Applied Systems Analysis and international collaborators.

The scent of a man
Scientists' inability to replicate research findings using mice and rats has contributed to mounting concern over the reliability of such studies. Now, an international team of pain researchers led by scientists at McGill University in Montreal may have uncovered one important factor behind this vexing problem: the gender of the experimenters has a big impact on the stress levels of rodents.

Plants send out signals attracting harmful bacteria, MU study finds
When bacteria attack plants, they often inject harmful proteins into the host plants' cells to weaken and suppress natural defenses. Now, researchers at the University of Missouri have identified and replicated the process that allows the bacteria -- known mostly for attacking tomatoes -- to invade its host. This discovery could lead to natural anti-infective treatments that work with food-producing plants to enhance resistance to harmful bacteria in the field.

Study: Altruistic adolescents less likely to become depressed
It is better to give than to receive -- at least if you're an adolescent and you enjoy giving, a new study suggests. The study found that 15- and 16-year-olds who find pleasure in pro-social activities, such as giving their money to family members, are less likely to become depressed than those who get a bigger thrill from taking risks or keeping the money for themselves.

Animals with bigger brains, broader diets have better self control
A new study representing the largest study of animal intelligence to-date finds that animals with bigger brains and broader diets have better self-control. Published this week in Proceedings of the National Academy of Sciences, the results are part of a long history of research aimed at understanding why some species are able to do things like make and use tools, read social cues, or even understand basic math, and others aren't.

How a plant beckons the bacteria that will do it harm
A common plant puts out a welcome mat to bacteria seeking to invade, and scientists have discovered the mat's molecular mix. The team showed that the humble and oft-studied plant Arabidopsis puts out a molecular signal that invites an attack from a pathogen. The study reveals new targets during the battle between microbe, which often infects tomatoes, and host that researchers can exploit to protect plants.

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.

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.
