Michael J. O'Reilly, of Chaumont, graduated from SUNY Cortland in 1958. His bequest is the second largest individual gift in the college's history. The school will receive the money when O'Reilly dies. It will be used to create the Michael J. O'Reilly '58 Scholarship in Science Teacher Education. The scholarship targets talented undergraduate and graduate students with financial need who want to enter a junior high or senior high school teaching career. O'Reilly's first job was as a junior high science teacher in the Fayetteville-Manlius School District. He has spent the last 28 years teaching science in the East Ramapo Central School District. A Watertown native, O'Reilly earned a bachelor's degree in elementary education in 1958, and a master's degree in education in 1963 at Cortland. He later received a fellowship to attend the University of Pennsylvania for a master's degree in education. Five Filters featured article: Chilcot Inquiry.

A growing wealth of evidence from fossil records, modern genetics, biochemistry, and field biology is clarifying the picture of how life evolved on Earth over the last three billion years and how it continues to change. Missing links are being filled in and evolution is being witnessed live in action. Now researchers are beginning to discover how to leverage the power of modern computing simulations to explore pressing questions in the field of evolutionary biology. Scientists at the University of Minnesota's Institute of Technology have just completed a study which uses hydrodynamic simulations of fish to help understand how their environment helped shape their evolution. Civil Engineering Professor Fotis Sotiropoulos and postdoctoral researcher Iman Borazjani began the project over five years ago, looking to simulate the model fish in a massive parallel computer cluster. The work was quite challenging. Describes Professor Sotiropoulos, "It was a challenge because we had never simulated anything living before." However, the pair were able to use their strong knowledge of hydrodynamics to develop a plan of attack. They created four swimming fish -- two computational mackerels (one that beat its tail like a mackerel and a second that wriggled like an eel) and two eels (one that wriggled and another that beat its tail like a mackerel). They then sent the digital fish out through a variety of water conditions, varying the fluid velocity-dependent viscosity. They then examined the fish traveling at various tail-beat speeds and looked at the efficiency of the motion. What they found was that fish with inappropriate tail motions or body shapes moved less efficiently, which in the real world would equate to tiring quicker. Tiring quicker could lead to losing the chance to catch prey or, worse yet, being eaten. In slow currents (such as a reef) the eel shape was preferred, while in fast currents (open sea) mackerel shape was preferred. Thus the research shows important evidence of how selective pressures may have given rise to fish in their modern shape. It also demonstrates how computer simulations can be used to better understand natural selection and the course of evolution. Professor Sotiropoulos is quite pleased with the results. He states, "From these experiments, we can deduce that real mackerel and eel's swimming styles are perfectly adapted to the hydrodynamic environments that they inhabit."

| Scientists measure viral energy - United Press International Posted: 08 Feb 2010 07:11 AM PST Message from fivefilters.org: If you can, please donate to the full-text RSS service so we can continue developing it. PITTSBURGH, Feb. 8 (UPI) -- A U.S. physicist says he has, for the first time, directly measured the energy associated with the expulsion of viral DNA into a cell. Carnegie Mellon University Associate Professor Alex Evilevitch said his team's accomplishment could lead to fully understanding viral infections, resulting in new drugs to interfere with the process. "We are studying the physics of viruses, not the biology of viruses," said Evilevitch. "By treating viruses as physical objects, we can identify physical properties and mechanisms of infection that are common to a variety of viruses, regardless of their biological makeup, which could lead to the development of broad spectrum antiviral drugs." Evilevitch said his current findings also have the potential to improve the development of gene therapy, which uses viruses to deliver functional genes directly to human cells to replace defective genes that are causing disease. Evilevitch and his colleagues from Lund University in Sweden and the University of Lyon in France said they used an experimental technique to directly measure the heat, and thus the thermal energy, released during viral genome ejection. Until now, only indirect measurements of this energy have been available. They describe their new method in the Feb. 5 issue of the Journal of Molecular Biology.

S. cerevisiae is a model organism commonly used in molecular biology to study basic cellular phenomena such as the regulation of gene expression, DNA replication or, as in the present case, DNA repair. DNA, which forms the genetic material of our cells, is continuously under stress challenging its integrity. On average, the DNA contained in each one of our cells suffers, on a daily basis, about 1 million damages. If not repaired, those genetic damages can lead to cancers. Hopefully, each cell has mechanisms that detect and then repair these injuries. It has long been known that some areas of the genome were more susceptible to be damaged than others. However, a complete list of those fragile areas had not been drafted until now. The researchers made an unexpected discovery as they analyzed the newly identified fragile sites. They found that many of those fragile sites were located in regions of the genome that contained inactive genes. "This observation was quite surprising, commented DNA damages tend to occur at these fragile sites and they play a key role in cancers. Since the methods that were used for this study can easily be adapted to human cells, this key phenomenon in cancer development could be better understood. "The research that Drs. Durocher and Robert and their teams have undertaken improves our ability to identify changes in DNA, and increases our understanding of how these changes influence the likelihood of developing cancer," said References for this article are available at: http://www.nature.com/nsmb/journal/vaop/ncurrent/index.html Dr. François Robert is Assistant Research Professor IRCM and Director of the Chromatin and Genomic Expression Research Unit at the IRCM. He is also Assistant Research Professor in the Department of Medicine at Université de Montréal, and Adjunct Professor in the Department of Biology at the Université de Sherbrooke. He is a recipient of the Maud Menten New Principal Investigator Prize-Biomedical Theme awarded by the Canadian Institutes of Health Research (CIHR) Institute of Genetics (IG). Established in 1967, the IRCM (www.ircm.qc.ca) now has 36 research units specialized in areas as diverse as immunity and viral infections, cardiovascular and metabolic diseases, cancer, neurobiology and development, systems biology and medicinal chemistry, clinical research and bioethics. It has a staff of more than 450 people. The IRCM is an independent institution, affiliated with the Université de Montréal and its clinic is associated to the Centre hospitalier de l'Université de Montréal (CHUM). The IRCM holds a close collaboration with McGill University.
