UD alumna studies leatherback sea turtles in Costa Rica

It’s not every day that you get to see a creature that has been around for 110 million years emerge from the ocean and lay its eggs on the beach. Unless, of course, you’re like University of Delaware graduate Lauren Cruz, who spends her days in Costa Rica with the Leatherback Trust studying leatherback sea turtle nesting ecology.

Cruz, a 2013 graduate who studied wildlife conservation in UD’s College of Agriculture and Natural Resources, is tracking the demographics of the turtles that nest at Playa Grande and Parque Nacional de las baulas — which translates to the park of leatherback sea turtles — and spends her nights with a team patrolling the beach looking for nesting turtles.

UCLA’s undergraduate researchers: ‘We’re going to have an impact on the future’

Serena Lee aspires to increase our understanding of people living with “invisible disabilities.” Amy Stuyvesant wants to figure out how changes in hurricane activity are helping or hindering the forests of Puerto Rico.

Although their subjects of their research are unrelated, these two graduating seniors share a key distinction. Thanks to the Wasserman Undergraduate Scholars Program, they are pursuing high-level research that they expect to have an impact far beyond UCLA. (more…)

A tangle of talents untangles neurons

Brown’s growing programs in brain science and engineering come together in the lab of Diane Hoffman-Kim. In a recent paper, her group employed techniques ranging from semiconductor-style circuit patterning to rat cell culture to optimize the growth of nerve cells for applications such as reconstructive surgery.

PROVIDENCE, R.I. [Brown University] — Two wrongs don’t make a right, they say, but here’s how one tangle can straighten out another.

Diane Hoffman-Kim, associate professor of medicine in the Department of Molecular Pharmacology, Physiology, and Biotechnology, is an affiliate of both Brown’s Center for Biomedical Engineering and the Brown Institute for Brain Science. Every thread of expertise woven through those multidisciplinary titles mattered in the Hoffman-Kim lab’s most recent paper, led by graduate student Cristina Lopez-Fagundo. (more…)

Sea Turtles Benefiting From Protected Areas

Study Offers First Look at Green Sea Turtle Habitat Use in the Dry Tortugas

DRY TORTUGAS, Fla. – Nesting green sea turtles are benefiting from marine protected areas by using habitats found within their boundaries, according to a U.S. Geological Survey study that is the first to track the federally protected turtles in Dry Tortugas National Park.

Green turtles are listed as endangered in Florida and threatened throughout the rest of their range, and the habits of green sea turtles after their forays to nest on beaches in the Southeast U.S. have long remained a mystery. Until now, it was not clear whether the turtles made use of existing protected areas, and few details were available as to whether they were suited for supporting the green sea turtle’s survival.

CU Research Shows Warming Climate Threatens Ecology at Mountain Research Site West of Boulder

A series of papers published this month on ecological changes at 26 global research sites — including one administered by the University of Colorado Boulder in the high mountains west of the city — indicates that ecosystems dependent on seasonal snow and ice are the most sensitive to changes in climate.

The six papers appeared in the April issue of the journal BioScience. The papers were tied to data gathered at sites in North America, Puerto Rico, the island of Moorea near Tahiti, and Antarctica, which are known as Long-Term Ecological Research, or LTER, sites and are funded by the National Science Foundation. CU-Boulder’s Niwot Ridge site, one of the five original LTER sites designated by NSF in 1980, encompasses several thousand acres of subalpine forest, tundra, talus slopes, glacial lakes and wetlands stretching up to more than 13,000 feet on top of the Continental Divide.

It Takes a Community of Soil Microbes to Protect Plants From Disease

*Berkeley Lab scientists decipher immune system for plants beneath our feet*

Those vegetables you had for dinner may have once been protected by an immune system akin to the one that helps you fight disease. Scientists from the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the Netherland’s Wageningen University found that plants rely on a complex community of soil microbes to defend themselves against pathogens, much the way mammals harbor a raft of microbes to avoid infections.

The scientists deciphered, for the first time, the group of microbes that enables a patch of soil to suppress a plant-killing pathogen. Previous research on the phenomenon of disease-suppressive soil had identified one or two pathogen-fighting microbes at work. (more…)

Scary Chupacabras Monster is as Much Victim as Villain

ANN ARBOR, Mich.— As Halloween approaches, tales of monsters and creepy crawlies abound. Among the most fearsome is the legendary beast known as the chupacabras.

But the real fiend is not the hairless, fanged animal purported to attack and drink the blood of livestock; it’s a tiny, eight-legged creature that turns a healthy, wild animal into a chupacabras, says University of Michigan biologist Barry OConnor. (more…)
