Rosenstiel School Alumni Lecture focuses on pharmacologic and chemical uses of sponges


Mar
2
5:30 pm

Marine biotechnology researcher Shirley Pomponi will share her research on sponges and their uses beyond the marine ecosystem as the keynote speaker of the University of Miami Rosenstiel School of Marine and Atmospheric Science’s Seventh Annual Alumni Lecture.

Pomponi, executive director of ocean science, technology, and development at Harbor Branch Oceanographic Institute at Florida Atlantic University, will present her research on Tuesday, March 2 at 5:30 p.m. in the Rosenstiel School Auditorium.

Pomponi’s research focuses on marine biotechnology in general and on sponge cell culture in particular. Sponges have been around for more than 600 million years, and one reason that they’ve been so successful is because they have evolved a sophisticated chemical cache that enables them to compete for space, defend against predators, communicate with other sponges, reproduce, and even prevent infections. These same chemicals are being studied for their potential development as drugs to treat human disorders and diseases.

When it is not ecologically feasible to harvest sponges to obtain enough of beneficial chemicals for drug development or marketing, the most common option is synthesis of the chemical in the lab. Pomponi, who received her Ph.D. from the Rosenstiel School in 1978, and her team are exploring ways to grow sponge cells and stimulate them in order to produce these beneficial chemicals for pharmacological uses.

UM researcher: Dust from distant lands may affect climate in the Americas and Europe



Dust plumes emerging from glacial outwash deposits on the southeast coast of Iceland.

Residents of the southern United States and the Caribbean have seen it many times during the summer months—a whitish haze in the sky that seems to hang around for days. The resulting thin film of dust on their homes and cars actually is soil from the deserts of Africa, blown across the Atlantic Ocean.

Now there is new evidence that dust storms in the Arctic, possibly caused by receding glaciers, may be making similar deposits in northern Europe and North America, according to University of Miami researcher Joseph M. Prospero in a February 19 presentation to the American Association for the Advancement of Science.

“Our recent work in Iceland has shown that most of the dust events there are associated with dust emitted from glacial outwash deposits, which may be carried into the northern latitudes and into Europe by synoptic weather events,” says Prospero, professor of marine and atmospheric chemistry at UM’s Rosenstiel School of Marine and Atmospheric Science, in his talk “Intercontinental Dust Transport: The Linkage to Climate and Its Environmental Impact.”

Rosenstiel School geochemist Millero named AAAS fellow



Frank J. Millero

Frank J. Millero, professor of marine and atmospheric chemistry at the Rosenstiel School of Marine and Atmospheric Science, has been elected a fellow of the American Academy for the Advancement of Science (AAAS). A fellow is defined as “a member whose efforts on behalf of the advancement of science or its applications are scientifically or socially distinguished.”

A thought leader in the application of physical chemistry to natural waters, Millero has helped to define this field of endeavor for the last four decades. His scientific output is notable for its depth and quality. Millero’s earliest and most widely cited works include those that feature the measurement and parameterization of molar volumes and compressibility of electrolytes, and the equation of state for seawater. His research on the carbonate system in the world’s oceans has contributed to our understanding of changes in the global flux of CO2 across the air-sea interface and the oceanic uptake of this greenhouse gas.

His publications span the physical chemistry of natural systems work on molar volumes and compressibility to thermochemical measurements; physical and chemical properties of water and seawater; models of ionic interactions and physical properties of electrolytes; effects of pressure on ionic equilibria; kinetics; bacteria interactions with metals and surfaces; and particle-metal interactions. He has published more than 413 articles in refereed journals, 32 book chapters, five books, and numerous reports and abstracts. Particularly noteworthy publications include his three editions of Chemical Oceanography (1991, 1996, and 2006) and his book Physical Chemistry of Natural Waters (2000).

Millero has been recognized with numerous awards and honors, such as Sigma Xi Professor of the Year (1989), the ONR Ocean Educator Award (1990), University of Miami Distinguished Faculty Scholar Award (1996), University of Miami Provost Award for Scholarly Activity (1998-1999), and the American Chemistry Society Geochemistry Division Medal (2001).

Satellite observations reveal Haiti earthquake facts and future risk



The images were obtained using data from Japan’s ALOS satellite and made available to the scientific community through the efforts of the European Space Agency and GEO, the Group of Earth Observation.

Scientists at the University of Miami have analyzed images based on Synthetic Aperture Radar (SAR) observations taken before and just after Haiti’s earthquake on January 12. The images reveal surprising new details.

The images were obtained using data from Japan’s ALOS satellite and made available to the scientific community through the efforts of the European Space Agency and GEO, the Group of Earth Observation, an umbrella group of many countries that promotes the exchange of satellite data to efficiently observe our planet.

According to the new data, the earthquake rupture did not reach the surface—unusual for a quake this size. More importantly, the images confirm that only the western half of the fault segment that last ruptured in 1751 actually ruptured in the current earthquake. “We’re still waiting for the other shoe to drop,” says Tim Dixon, professor of geology and geophysics at UM’s Rosenstiel School of Marine and Atmospheric Science.

Stimulus response


With support from close to $90 million in stimulus-backed grant awardsand countingfrom various federal agencies, University of Miami investigators have embarked on research projects aimed at finding solutions to some of the world’s most pressing problems.

Stimulus-backed research is being conducted on UM's Coral Gables, Miller School, and Rosenstiel School campuses.

The bioreactor that will enable Weiyong Gu to analyze the growth characteristics of intervertebral tissue without having to remove samples from the device hasn’t even been invented yet. But the University of Miami biomedical engineer is in a race against time, working long hours in his lab to build the instrument that could help pave the way for advanced techniques in the engineering of human tissue to replace organs.

At UM’s Rosenstiel School of Marine and Atmospheric Science, the challenge that confronts geochemist Peter Swart lies not in building a new device, but in using existing tools to determine whether the technique of carbon capture can actually help solve the global-warming crisis.

Both investigators are conducting their research with the blessing and backing of Uncle Sam. They are beneficiaries of hefty grants that have been flowing from the federal government’s coffers ever since the American Recovery and Reinvestment Act (ARRA) pumped $10.4 billion into the National Institutes of Health, with $8.2 billion earmarked for scientific research priorities.

Practicing Prose


SwanOpportunities to acquire effective writing skills can be rare in science. Such an opportunity came to the Rosenstiel School of Marine and Atmospheric Science last month, when the school served as the site of a writing workshop led by Judith Swan. Swan, associate director of the Writing Program at Princeton University, is co-author the seminal paper “The Science of Science Writing.” Almost 180 people registered for the daylong workshop, which covered strategies for writing clearly and compellingly. The workshop was funded through a SEEDS (Scientists and Engineers Expanding Diversity and Success) You Choose Award to Paquita Zuidema, assistant professor of meteorology and physical oceanography. Above: Rosenstiel meteorology and physical oceanography researcher Gustavo Carvalho, right, consults with Swan during a break.

From left, professor of marine biology and fisheries Sharon Smith, Rosenstiel School Dean Roni Avissar, Miller and Rosenstiel researcher Lora Fleming, and Miller School Dean Pascal J. Goldschmidt at the BMAA and The Brain conference.

The University of Miami’s Rosenstiel School of Marine and Atmospheric Science and the Leonard M. Miller School of Medicine joined forces with the Institute of Ethnomedicine and the Center for Oceans and Human Health at UM for a dialogue on “BMAA and the Brain” held on November 4. The program, introduced jointly by Rosenstiel School Dean Roni Avissar and Miller School Dean Pascal J. Goldschmidt, highlighted the University’s unique interdisciplinary research in Oceans and Human Health and efforts now under way in ethnomedicine, neurosciences, toxicology, marine biology, and oceanography.

One noteworth project involves research into cyanobacteria (blue-green algae) found on land and in freshwater and the oceans that can produce BMAA, an environmental neurotoxin that affects humans and animals. BMAA has been linked to age-related neurodegenerative diseases such as Alzheimer’s, ALS, and Parkinson’s in humans.

Paul Cox of the Institute of Ethnomedicine discussed the genesis of his studies in Guam and the widespread neurological disease associated with the Chamorro people, which is now being linked to the ingestion of animals that eat cycads with cyanobacteria. Deborah Mash, director of UM’s Brain Endowment Bank who is currently testing for BMAA in postmortem human brain samples, spoke of the vital importance of the brain biorepository and the preliminary findings she and her team are making in their studies of neurodegenerative brains and control brains.

Larry Brand, a professor at the Rosenstiel School discussed BMAA as a toxin in the marine food web.

The discussion was followed by a reception hosted by the codirectors of the Center for Oceans and Human Health, Lora Fleming, who holds joint appointments at in epidemiology and public health at the Miller School and marine biology and fisheries at Rosenstiel, and Sharon Smith, professor of marine biology and fisheries.
