{DISSERTATION} Vanderbilt researchers pioneer an advanced sepsis detection and management system An interdiscipinary team of clinicians and informatics experts from the Vanderbilt University Medical Center and computer scientists from Vanderbilt's Institute for Software Integrated Systems have developed and begun testing what they believe is the first real-time system for sepsis detection.

 Astrophysical Journal{DISSERTATION} Meteorite grains divulge Earth's cosmic roots The interstellar stuff that became incorporated into the planets and life on Earth has younger cosmic roots than theories predict, according to the University of Chicago postdoctoral scholar Philipp Heck and his international team of colleagues.

Physical Review Letters{DISSERTATION} Caltech scientists use high-pressure 'alchemy' to create nonexpanding metals By squeezing a typical metal alloy at pressures hundreds of thousands of times greater than normal atmospheric pressure, scientists at the California Institute of Technology have created a material that does not expand when heated, as does nearly every normal metal, and acts like a metal with an entirely different chemical composition.

Proceedings of the National Academy of Sciences{DISSERTATION} Stress puts double whammy on reproductive system, fertility Stress is known to decrease fertility and sexual behavior, but researchers thought this was because stress hormones lower levels of a brain hormone called gonadotropin releasing hormone, or GnRH. UC Berkeley biologists now show that stress hormones also boost levels of a hormone that suppresses GnRH -- a double whammy. The scientists hope it will be possible to block this hormone, called gonadotropin inhibiting hormone, or GnIH, and restore fertility.

Science Express{DISSERTATION} New exotic material could revolutionize electronics Move over, silicon -- it may be time to give the Valley a new name. Physicists at the US Department of Energy's SLAC National Accelerator Laboratory and Stanford University have confirmed the existence of a type of material that could one day provide dramatically faster, more efficient computer chips.

{DISSERTATION} D.C. Math for America awarded $1.5-million NSF grant In 2008, the Carnegie Institution's Carnegie Academy for Science Education launched a partnership with Math for America and American University. The program is to improve the mathematics education of Washington, D.C., public and public charter secondary school students by selecting and educating fellows to become skilled teachers. Using stimulus funds, the National Science Foundation has just awarded MfA DC a $1.498-million grant to cover costs for the first 14 fellows.

Nature Materials{DISSERTATION} NYU researchers create method to precisely glue particles together on the micro- and nano-scale Researchers at New York University have created a method to precisely bind nano- and micrometer-sized particles together into larger-scale structures with useful materials properties. Their work, which appears in the latest issue of the journal Nature Materials, overcomes the problem of uncontrollable sticking, which had been a barrier to the successful creation of stable microscopic and macroscopic structures with a sophisticated architecture.

Nature Cell Biology{DISSERTATION} Advance in understanding cellulose synthesis Cellulose makes up plant cell walls, gives plants shape and form and is a target of renewable, plant-based biofuels research. But how it forms, and thus how it can be modified to design energy-rich crops, is not well understood. Now a study led by researchers at the Carnegie Institution has discovered that the underlying protein network that provides the scaffolding for cell-wall structure is also the traffic cop for delivering critical growth-promoting molecules where needed.

Cell{DISSERTATION} Protein that triggers plant cell division revealed by researchers Stanford biologists have found a plant protein that appears to play a key role in asymmetric cell division. The presence of the protein, called BASL, is vital to such division. In plant cells where it was absent, the cells did not divide. "This is crucial information if we really want to understand plants' unique ways of making the different types of cells in their bodies," said Dominique Bergmann, an assistant professor of biology.

Science{DISSERTATION} Maple seeds and animals exploit the same trick to fly The twirling seeds of maple trees spin like miniature helicopters as they fall to the ground. Because the seeds descend slowly as they swirl, they're carried aloft by the wind and dispersed over great distances. Just how the seeds manage to fall so slowly, however, has mystified scientists. In research published in the June 12 Science, researchers from Wageningen University in the Netherlands and Caltech describe the aerodynamic secret of the enchanting swirling seeds.

Science{DISSERTATION} Abrupt global warming could shift monsoon patterns, hurt agriculture At times in the distant past, an abrupt change in climate has been associated with a shift of seasonal monsoons to the south, a new study concludes, causing more rain to fall over the oceans than in the Earth's tropical regions, and leading to a dramatic drop in global vegetation growth.

Geophysical Research Letters{DISSERTATION} Maybe it's raining less than we thought It's conventional wisdom in atmospheric science circles: Large raindrops fall faster than smaller drops because they're bigger and heavier. And no raindrop can fall faster than its "terminal speed." Now a team of physicists has determined that it ain't necessarily so.

American Naturalist{DISSERTATION} Evolution can occur in less than 10 years How fast can evolution take place? In just a few years, according to a new study on guppies led by Swanne Gordon, a graduate student in the Department of Biology at the University of California, Riverside. Gordon and her colleagues found that guppies introduced to a low-predation environment adapted to their new environment by producing larger and fewer offspring with each reproductive cycle. No such adaptation was seen in guppies that colonized a high-predation environment.

Proceedings of the National Academy of Sciences{DISSERTATION} Penn materials scientist finds plumber's wonderland on graphene Engineers from the University of Pennsylvania, Sandia National Laboratories and Rice University have demonstrated the formation of interconnected carbon nanostructures on graphene substrate in a simple assembly process that involves heating few-layer graphene sheets to sublimation using electric current that may eventually lead to a new paradigm for building integrated carbon-based devices.

Astronomical Journal{DISSERTATION} Peculiar, junior-sized supernova discovered by New York teen In November 2008, Caroline Moore, a 14-year-old student from upstate New York, discovered a supernova in a nearby galaxy, making her the youngest person ever to do so. Additional observations determined that the object, called SN 2008ha, is a new type of stellar explosion, 1000 times more powerful than a nova but 1000 times less powerful than a supernova. Astronomers say that it may be the weakest supernova ever seen.

Neuron{DISSERTATION} How young mice phone home: Study gives clue to how mothers' brains screen for baby calls Emory University researchers have identified a surprising mechanism in the brains of mother mice that focuses their awareness on the calls of baby mice. Their study found that the high-frequency sounds of mice pups stand out in a mother's auditory cortex by inhibiting the activity of neurons more attuned to lower frequency sounds.

American Astronomical Society Meeting Astrophysical Journal Letters{DISSERTATION} Red giant star Betelgeuse is mysteriously shrinking The red supergiant star Betelgeuse, which is so large it would extend to Jupiter's orbit in our solar system, has steadily shrunk over the past 15 years, according to UC Berkeley physicists. Since 1993, its radius has gone down by 15 percent, equivalent to the radius of Venus's orbit. This conclusion comes from unique laser interferometer observations by laser inventor and Nobel Laureate Charles Townes and his colleague, Edward Wishow.
