Supercomputer Simulations Show How DNA Prepares Itself for Repair

Researchers from Harvard University and the University of Texas Medical Branch at Galveston recently used the Comet supercomputer at the San Diego Supercomputer Center (SDSC) at the University of California San Diego to uncover the novel ways in which DNA prepares itself for repair.

Biohybrid Model Uses Organic Lungs, Synthetic Muscles to Re-Create Respiration Mechanics

Discussed in APL Bioengineering, researchers created a high-fidelity respiratory simulator that accurately represents the interplay between the abdomen, diaphragm, lungs and pleural space, the fluid-filled membrane surrounding the thorax and lungs. The model, using swine lungs, soft robotic materials and artificial muscles, allows precise tuning of pressure in each part of the system, so specific disease conditions can be tested. It also proved extremely useful for testing ventilator-only respiration by removing the elastomeric diaphragm.

Bone Researcher Provides Expert Commentary in Publication’s Controversial Reversal of Long-Held Theory

The latest issue of PLOS Genetics includes two publications that challenge the basic assumptions behind 24 years of bone and metabolism research, and given the magnitude of the potential paradigm shift, the editors turned to Stavros C. Manolagas, M.D., Ph.D., of the University of Arkansas for Medical Sciences (UAMS) to provide expert commentary and context.

Rutgers’ Greg Moore Elected to National Academy of Sciences

Rutgers Professor Gregory W. Moore, a renowned physicist who seeks a unified understanding of the basic forces and fundamental particles in the universe, has been elected to the prestigious National Academy of Sciences. Moore, Board of Governors Professor in the Department of Physics and Astronomy at Rutgers University–New Brunswick, joins 119 other new academy members and 26 international members this year who were recognized for their distinguished and ongoing achievements in original research.

Each Mediterranean island has its own genetic pattern

A Team around Anthropologist Ron Pinhasi from the University of Vienna – together with researchers from the University of Florence and Harvard University – found out that prehistoric migration from Africa, Asia and Europe to the Mediterranean islands took place long before the era of the Mediterranean seafaring civilizations.

Technique Can Label Many Specific DNAs, RNAs, or Proteins in a Single Tissue Sample

A new technique can label diverse molecules and amplify the signal to help researchers spot those that are especially rare. Called SABER (signal amplification by exchange reaction), Peng Yin’s lab at Harvard’s Wyss Institute first introduced this method last year and since have found ways to apply it to proteins, DNA and RNA.

Native Americans did not make large-scale changes to environment prior to European contact

Contrary to long-held beliefs, humans did not make major changes to the landscape prior to European colonization, according to new research conducted in New England featuring faculty at Binghamton University, State University of New York. These new insights into the past could help to inform how landscapes are managed in the future.

Studying Ice to Understand Astrophysical Bodies

Understanding the formation and evolution of ice in astrophysical environments can provide information about the physical conditions encountered in space and the chemical similarities and differences between planetary and stellar systems. At the AVS 66th International Symposium and Exhibition, Edith Fayolle, an astrochemist at NASA’s Jet Propulsion Laboratory, will talk about how scientists are trying to understand properties of ice on astrophysical bodies, such as its formation, composition and sublimation — the process by which ice transitions directly into gas, without being in its liquid phase in between.
