Materials science is a field that Jason Trelewicz has been interested in since he was a young child, when his father — an engineer — would bring him to work. In the materials lab at his father’s workplace, Trelewicz would use optical microscopes to zoom in on material surfaces, intrigued by all the distinct features he would see as light interacted with different samples. Trelewicz is now an assistant professor in the College of Engineering and Applied Sciences’ Department of Materials Science and Chemical Engineering with a joint appointment in the Institute for Advanced Computational Science at Stony Brook University…

The study of objects less than a billionth of a meter, also known as “nanometers,” is a special research discipline that Materials Science and Engineering Professor Alexander Orlov has been working on for years. A major breakthrough in this field has been the emergence of a new generation of consumer products containing nanoparticles, nano-enabled biomedical devices and many other exciting developments straight out of science fiction novels. However, like many scientific breakthroughs, there is hesitation in the implementation of nanotechnology. “It is a very difficult area to describe, as you cannot see nanoparticles with the naked eye,” Orlov explained. “People…

New York Sea Grant Director Bill Wise participated in a legislative briefing, “Using Science and Outreach to Assist State and Local Decision Makers in Disaster Preparedness and Public Safety,” on November 8 in Washington, DC, which was sponsored?by Congressmen Lee Zeldin (NY)?and Joe Courtney (CT). Wise and others on the panel conveyed the importance of the National Sea Grant College Program (Sea Grant) to Congressional leaders. Specifically, he discussed the Coastal Storm Awareness Program (CSAP), funded with $1.8 million from the National Oceanic and Atmospheric Administration. This program was initiated after Superstorm Sandy to help understand the factors that influenced…

Although filled with tropical life?today, the Caribbean islands?have?been a?hotspot?of mammal extinction?since the end of the last glaciation, some 12,000 years ago.?Since people also?arrived after that time, it has been?impossible to determine whether natural changes or human influence?are most responsible for these extinctions. A new study by an?international team of scientists, including Stony Brook University Professor?Liliana M. Dávalos,?reports an analysis of the incredibly diverse “lost world” of?Caribbean fossils?that includes giant rodents, vampire bats, enigmatic monkeys, ground sloths, shrews and dozens of other ancient mammals.?The study, published today in the?Annual Review of Ecology, Evolution, and Systematics, reveals that the arrival of humans…

A new study published in?PNAS?details a new “landscape portfolio” theory that uses insights from economics to predict animal population growth and the spread of disease. The paper, co-authored by Stony Brook’s Jessica Gurevitch, PhD, a Professor in the Department of?Ecology and Evolution?in the?College of Arts and Sciences, melds Harry Markowitz’s “portfolio theory” in economics with ecological landscape theory to predict population growth of living things. Population demography of plants, animals and microbes that cause diseases is central to understanding many problems in ecology, evolution and conservation biology. Scientists have had limited information on collections of living populations to understand and…

As representatives from around the world meet in Bonn, Germany this month to discuss a way forward on the Paris Agreement and decarbonization, a new book on energy transitions by?Kathleen Araújo, assistant professor in the Department of Technology and Society in the College of Engineering and Applied Sciences, sheds light on the experiences of countries managing the transition to low carbon technologies. Low Carbon Energy Transitions: Turning Points in National Policy and Innovation?(Oxford University Press)?draws on over 120 interviews with scientists, governmental employees, academics, and members of civil society. Araújo focuses on four unique cases: Brazilian biofuels, Danish wind power,…

For his work focusing on the risks involved in deploying fully autonomous computer systems, Romeil Sandhu has been awarded $450K from the Air Force Office of Scientific Research (AFOSR), through the Air Force’s Young Investigator Research Program. Sandhu is an assistant professor in the Department of Biomedical Informatics, jointly administered by Stony Brook’s?College of Engineering and Applied Sciences?and?School of Medicine. His research could impact autonomous systems for a variety of systems that rely on artificial Intelligence, including self-driving automobiles and drones. Professor Sandhu is one of only 43 scientists and engineers to receive the award, for his proposal addressing?3D Interactive…

A new study from world’s leading lemur expert paints a grim picture for future of dietary specialists like the?critically endangered Greater Bamboo Lemur. Human disturbance of tropical rainforests in Madagascar, including wildfires, burning and timber exploitation, have led to reduced rainfall and a longer dry season, further pushing the Greater Bamboo Lemur to the brink of extinction. Findings are published in a new study from primatologist and lemur expert, Patricia Chapple Wright of Stony Brook University, evolutionary biologist Jukka Jernvall of University of Helsinki in Finland, and colleagues. The study is entitled Feeding Ecology and Morphology Make a Bamboo Specialist…

Scientists from Stony Brook University’s School of Marine and Atmospheric Sciences (SoMAS) will be developing seasonal predictions of fish and marine mammal distributions in the Northeast United States with the goal to enhance protected species management. The research is supported by a $509,573 grant from the National Oceanic and Atmospheric Administration’s (NOAA) National Marine Fisheries Service Office of Science and Technology, in partnership withNOAA Research’s Modeling, Analysis, Predictions, and Projections (MAPP) Program. The Northeast U.S. large marine ecosystem is highly productive and supports important commercial and recreational fisheries. It has also experienced some of the highest warming rates in recent…

Scientists from Stony Brook University have used a novel technique at the?National Synchrotron Light Source II?(NSLS-II), a U.S. Department of Energy (DOE) Office of Science User Facility located at Brookhaven National Laboratory,?to answer longstanding questions in medical imaging. The research team used individual x-rays to characterize the physics of how light moves within scintillators—a component of x-ray detectors—for the very first time.?Their findings?could aid the development of more efficient x-ray detectors for improved medical diagnoses. X-ray imaging is a widespread technique for viewing the internal structures of matter. In the medical field, x-ray imaging is used to generate images of…
