 Proceedings of the National Academy of Sciences{DISSERTATION} Loss of coastal seagrass habitat accelerating globally An international team of scientists warns that accelerating losses of seagrasses across the globe threaten the immediate health and long-term sustainability of coastal ecosystems. The team has compiled and analyzed the first comprehensive global assessment of seagrass observations and found that 58 percent of world's seagrass meadows are currently declining.

Neurosurgical Focus{DISSERTATION} Reading the brain without poking it Experimental devices that read brain signals have helped paralyzed people use computers and may let amputees control bionic limbs. But existing devices use tiny electrodes that poke into the brain. Now, a University of Utah study shows that brain signals controlling arm movements can be detected accurately using new microelectrodes that sit on the brain but don't penetrate it.

PLoS Biology{DISSERTATION} Plant protein 'doorkeepers' block invading microbes, study finds A group of plant proteins that "shut the door" on bacteria that would otherwise infect the plant's leaves has been identified for the first time by a team of researchers in Denmark, the University of California -- Davis and University of California -- Berkeley.

Journal of Experimental Biology{DISSERTATION} Dolphins get a lift from delta wing technology Dolphins are supremely agile swimmers, but it wasn't clear how their fins help them maneuver though water. Building scale models of whale and dolphins' fins, a team of US scientists has found that some dolphins' fins work just like delta wing aircraft.

{DISSERTATION} Computers aid in cracking deception in plants If the growing presence of computer 'geeks' on television crime shows is any indicator, computers are increasingly becoming essential tools for detecting and combating skullduggery. However, television detectives are not the only ones taking advantage of these tools. Researchers also are beginning to collaborate with computer scientists to help uncover biological forms of deception, known as molecular mimicry.

American Journal of Botany{DISSERTATION} Study finds DNA barcoding requires caution without closer examination DNA barcoding is advocated as a vast improvement in our ability to monitor and manage the world's biodiversity. Dr. David Spooner, a USDA researcher and expert on the potato and tomato family, examined the utility of DNA barcoding in a complex plant group, Solanum section Petota, using three of the most frequently suggested genome sections. His findings emphasize the importance of using multiple means of identifying species, and he cautions against using barcoding alone as a means of species identification.

Geophysical Research Letters{DISSERTATION} Space shuttle science shows how 1908 Tunguska explosion was caused by a comet The mysterious 1908 Tunguska explosion that leveled 830 square miles of Siberian forest was almost certainly caused by a comet entering the Earth's atmosphere, says new Cornell University research. The conclusion is supported by an unlikely source: the exhaust plume from the NASA space shuttle launched a century later.

Nature{DISSERTATION} On malaria struggle, baboons and humans have similar stories to tell Evolutionarily speaking, baboons may be our more distant cousins among primates. But when it comes to our experiences with malaria over the course of time, it seems the stories of our two species have followed very similar plots.

{DISSERTATION} 'Mixed reality' human helps medical students learn to do intimate exams "What brings you in to see me today?" "Part of my left breast has been painful for awhile." "Can you lie down so that I can examine you?" It sounds like a snippet of conversation between doctor and patient. But the doctor, in this recent exchange at the University of Florida campus, was actually an engineering doctoral student -- and the patient a "mixed reality human" composed of a life-sized computer avatar on a flat screen and a mannequin with a prosthetic breast.

Proceedings of the Royal Society B{DISSERTATION} Changes in brain architecture may be driven by different cognitive challenges Scientists trying to understand how the brains of animals evolve have found that evolutionary changes in brain structure reflect the types of social interactions and environmental stimuli different species face. The study is the first to compare multiple species of related animals, in this case social wasps.

{DISSERTATION} Midget plant gets makeover A tiny plant with a long name helps researchers design new crops to help meet increasing demands for food, biofuels, industrial materials and new medicines. The genes, proteins, and other traits of this plant reside in the Arabidopsis Information Resource (TAIR) database. TAIR just released a new version of the genome sequence, which includes an array of improvements and novel features that promise to accelerate this critical research.

Proceedings of the National Academy of Sciences{DISSERTATION} Carnegie Mellon algorithm charts evolution of genetic networks during fruit fly life cycle A new algorithm developed by Carnegie Mellon University computer scientists has revealed for the first time how genetic networks in the fruit fly, Drosophila melanogaster, evolve during the insect's life cycle. The new algorithm, called Tesla, incorporates machine learning techniques that enable researchers to figure out how the rewiring of those networks takes place as the insect develops.

Proceedings of the National Academy of Sciences{DISSERTATION} Fighting TB might be a matter of 'flipping a switch' in immune response Scientists are focusing on a new concept in fighting airborne pathogens by manipulating what is called the "switching time," the point at which a highly regulated immune response gives way to powerful cells that specialize in fighting a specific invading bug. In the case of tuberculosis, Ohio State University researchers are using mathematical modeling to determine whether a change to the natural switching time would result in a more effective immune response.
