Genome of “extremophile” red alga offers insights
In the movie Alien, the title character is an extraterrestrial creature that can survive brutal heat and resist the effects of toxins.
In real life, organisms with similar traits exist, such as the “extremophile” red alga Galdieria sulphuraria.
In hot springs in Yellowstone National Park, Galdieria uses energy from the sun to produce sugars through photosynthesis. (more…)
Fat worms confirm that researchers from Michigan State University have successfully engineered a plant with oily leaves – a feat that could enhance biofuel production as well as lead to improved animal feeds.
The results, published in the current issue of The Plant Cell, the journal of the American Society of Plant Biologists, show that researchers could use an algae gene involved in oil production to engineer a plant that stores lipids or vegetable oil in its leaves – an uncommon occurrence for most plants.

If you could lick the surface of Jupiter’s icy moon Europa, you would actually be sampling a bit of the ocean beneath. A new paper by Mike Brown, an astronomer at the California Institute of Technology in Pasadena, Calif., and Kevin Hand from NASA’s Jet Propulsion Laboratory, also in Pasadena, details the strongest evidence yet that salty water from the vast liquid ocean beneath Europa’s frozen exterior actually makes its way to the surface.
The finding, based on some of the best data of its kind since NASA’s Galileo mission (1989 to 2003) to study Jupiter and its moons, suggests there is a chemical exchange between the ocean and surface, making the ocean a richer chemical environment. The work is described in a paper that has been accepted for publication in the Astronomical Journal. (more…)
Jaisi laboratory tracks chemicals in water, farmland throughout Mid-Atlantic
University of Delaware researcher Deb Jaisi is using his newly established stable isotope facility in the Environmental Biogeochemistry Laboratory (EBL) to find the fingerprints of isotopes in chemical elements — specifically phosphorus — in order to track sources of nutrients in the environmentally-sensitive Chesapeake Bay, other bodies of water and farmland throughout the Mid-Atlantic.
Jaisi, assistant professor in the Department of Plant and Soil Sciences in the College of Agriculture and Natural Resources, explained that he and his research team are currently working on many projects in the EBL, including two that are funded through seed grants, one focusing on terrestrial phosphorus sources and the other on marine phosphorus sources in the Chesapeake. One of those grants is from the UD Research Foundation (UDRF) and is titled “Role of Non-terrestrial Phosphorus Sources in Eutrophication in the Chesapeake Bay.” (more…)
The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now Yale School of Medicine researchers have reversed the process, recreating a youthful brain that facilitated both learning and healing in the adult mouse. (more…)
Antarctica’s topography began changing from flat to fjord-filled starting about 34 million years ago, according to a new report from a University of Arizona-led team of geoscientists.
Knowing when Antarctica’s topography started shifting from a flat landscape to one with glaciers, fjords and mountains is important for modeling how the Antarctic ice sheet affects global climate and sea-level rise. (more…)
Microsoft BizSpark startup improves communication and provides easy access to administrative resources combined with an educational social network.
REDMOND, Wash. — March 7, 2013 — During a trip to his home town in St. Petersburg, Russia, Gabriel Levi noticed that his local school system could modernize its services for educators and students by streamlining communication and reducing manual tasks. Using his entrepreneurial instincts, he saw a need and created a solution. Now Levi is CEO and founder of Classed In, where he has turned his mission into a thriving business with a comprehensive educational social network that connects teachers, students, administrators and parents at approximately 27,000 K–12 schools in Russia — more than half the country’s schools.
Levi attended college at Columbia University in New York and studied economics and computer science, while he dreamed of starting a business. When a work assignment took him back to St. Petersburg a few years later, he was struck by how Russian schools were still relying on completely manual processes for everything from registration and grade reporting to class assignments and homework. His point of reference was personal: Levi’s mother was a university instructor, and his younger brother was in middle school at the time. (more…)
Oculoplastic surgeons at the Yale Eye Center perform a range of procedures, from Botox injections to fix wrinkles, to lifesaving surgeries to help treat cancers near the eye.
(March 2013) Gail Chiasson’s “puffy eyelids” had gotten so heavy she felt as if they’d become permanently half-shut. Not only did she look sleepy, she felt sleepy. She couldn’t read a book for long and grew especially concerned when a doctor trying to perform an eye test had to tape her lids out of the way. (more…)
