 BioScience{DISSERTATION} Developing policy on moving threatened species called 'a grand challenge for conservation' An expert group of researchers publishes its consensus on the multiple factors that should be considered when managed relocation of a threatened species or other biological grouping is being considered as a response to climate change. Developing a functional policy framework for this controversial practice is "a grand challenge for conservation," the group writes.

{DISSERTATION} Glacier break creates ice island 2 times the size of Manhattan An ice island twice the size of Manhattan has broken off from Greenland's Petermann Glacier, according to researchers at the University of Delaware and the Canadian Ice Service. This is the second massive break in two years.

Proceedings of the National Academy of Sciences{DISSERTATION} Force of nature: Defining the mechanical mechanisms in living cells A multidisciplinary team of researchers at Stanford measured mechanical tension at the nanoscale to explore how living cells produce and detect force. The research could lead to a better understanding of how tissues and tumors form and grow, and, ultimately, to how complex living organisms organize themselves.

Proceedings of the National Academy of Sciences{DISSERTATION} To clean up the mine, let fungus reproduce Harvard-led researchers have discovered that an Ascomycete fungus that is common in polluted water produces environmentally important minerals during asexual reproduction. The key chemical in the process, superoxide, is a byproduct of fungal growth when the organism produces spores. Once released into the environment, superoxide reacts with the element manganese, producing a highly reactive mineral that aids in the cleanup of toxic metals, degrades carbon substrates, and controls the bioavailability of nutrients.

Proceedings of the National Academy of Sciences{DISSERTATION} Rodent robbers good for tropical trees A groundbreaking yearlong study in Panama suggests that squirrel-like agoutis have taken on the seed-spreading role of extinct mastodons and other elephant-like creatures, helping the black palm tree survive in the rainforest.

Proceedings of the National Academy of Sciences{DISSERTATION} Have thieving rodents saved tropical trees? Big seeds produced by many tropical trees were probably once ingested and then defecated whole by huge mammals called gomphotheres that dispersed the seeds over large distances. But gomphotheres were probably hunted to extinction more than 10,000 years ago. So why aren't large-seeded plants also extinct? A new report suggests that rodents may have taken over the seed dispersal role of gomphotheres.

Nature Photonics{DISSERTATION} Unique properties of graphene lead to a new paradigm for low-power telecommunications Columbia engineers have demonstrated remarkable optical nonlinear behavior of graphene that may lead to broad applications in optical interconnects and low-power photonic integrated circuits. Tthe researchers used graphene to transform the originally passive device into an active one that generated microwave photonic signals and performed parametric wavelength conversion at telecommunication wavelengths. Showing the power-efficiency of the device, they say, is an important advance in building all-optical processing elements essential to faster, more efficient, modern telecommunications.

Chemical Science{DISSERTATION} UMD creates new tech for complex micro structures for use in sensors & other apps University of Maryland Chemistry Professor John Fourkas and his research group have developed new materials and nanofabrication techniques for building miniaturized versions of components needed for medical diagnostics, sensors and other applications. These miniaturized components -- many impossible to make with conventional techniques -- would allow for rapid analysis at lower cost and with small sample volumes.

Nature{DISSERTATION} Messy experiment cleans up physics mystery of cornstarch Most people buy cornstarch to make custard or gravy, but Scott Waitukaitis and Heinrich Jaeger have used it to solve a longstanding physics problem with a substance known to generations of Dr. Seuss readers as "Oobleck," and to scientists as a non-Newtonian liquid. This substance, a liquid that can instantaneously turn into a solid under the force of a sudden impact, behaves in surprising ways.

Now, researchers from the US and South Korea have developed a warning system capable of forecasting the radiation from these violent solar storms nearly three hours (166 minutes) in advance, giving astronauts, as well as air crews flying over Earth's polar regions, time to take protective action.

Science{DISSERTATION} Discovery opens door to attacking biofilms that cause chronic infections Using super-resolution microscopy and continuous fluorescent imaging, UC Berkeley's Veysel Berk has for the first time revealed the structure of bacterial biofilms, which are responsible for the tenacious nature of bacterial diseases such as cholera, chronic sinusitis and lung infections in CF patients. The picture of bacterial apartment buildings provides new targets for the development of drugs that can tear down these structures and expose them to antibiotics.

Science{DISSERTATION} Oregon's Paisley Caves as old as Clovis sites -- but not Clovis A new study of Oregon's Paisley Caves confirms that humans used the site as early as 12,450 radiocarbon years ago, and the projectile points they left behind were of the "Western Stemmed" tradition and not Clovis -- which suggests parallel technological development of early inhabitants to the Americas.

Nature{DISSERTATION} Smart Materials get SMARTer Few synthetic materials are able to mimic the human body's ability to regulate itself -- until now. In the July 12 issue of Nature, a team of engineers from the University of Pittsburgh and Harvard University has presented a strategy for building self-regulating microscopic materials, ultimately paving the way toward so-called smart buildings with more energy-saving features and smarter biomedical engineering applications.

Psychological Science{DISSERTATION} Want to get teens interested in math and science? Target their parents Increasing the number of students interested in science, technology, engineering, and math – the STEM disciplines – is vital to national competitiveness in the global economy and to the development of a strong workforce. But the pipeline leading toward STEM careers begins leaking in high school, when students choose not to take advanced STEM courses. Now a new study goes beyond the classroom to examine the unique role that parents can play in promoting students' STEM motivation.
