It is widely known that adipose tissue has the ability to rapidly expand or contract in accordance with nutritional constraints. Recently, using a cell-sorting method known as flow cytometry, the researchers at the University of Pittsburgh School of Medicine detected a broad spectrum of blood-forming, or hematopoietic, cells among the cultured cells at varying stages of [...]

Cynthia Lin, a senior in mechanical engineering, part of team that built a solar-powered bottle sorter for the 2.009 product engineering class, which had the theme “reduce, reuse, recycle.” (Credit: Photo / Donna Coveney) Seven teams of 18 students in this year’s 2.009 Product Engineering Processes class, taught by David Wallace, are challenged to design something [...]

Imagine of tackling subjects like physics, calculus and chemist topics without being able to see the graphs and figures used to teach blinds. They have to study with a narrow imagination. Besides, there will be so many constraints in the study, while you know, they need to explore the subjects to understand it. Visual disabilities make [...]

Researchers from Clemson University have developed a new process and equipment that will lead to a significant reduction in heat generated by silicon chips or microprocessors while speeding up the rate at which information is sent. Rajendra Singh, D. Houser Banks Professor and director for the Center for Silicon Nanoelectronics said that, hopefully, the next generation [...]

Malaria is a vector-borne infectious disease caused by protozoan parasites. It is one of the most common infectious diseases and an enormous public health problem. No vaccine is currently available for malaria; but now, a research team led by Dr. Paul Wiseman of the Departments of Physics and Chemistry at McGill University has developed a radically [...]

Atherosclerosis, diabetes, hypertension, and cancer occur more frequently with increasing age, researchers at Washington University School of Medicine in St. Louis explained. By making the skeletal muscles of mice use energy less efficiently, researchers report that they have delayed the animals’ deaths and their development of age-related diseases. Clay Semenkovich said, although it does not extend maximum [...]

Greenland ’s ice sheet contains at least 10 percent of the world’s freshwater AND it has been losing more than 24 cubic miles (100 cubic kilometers) of ice annually for the last five years and 2007 was a record year for glacial melting there. Recently, annual meeting of the American Geophysical Union in San Francisco reported [...]

In the journal Advanced Materials, Yadong Wang, assistant professor in the Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, developed a treatment for recovering human nerve function. The technique would use a biodegradable polymer containing a chemical group that mimics the neurotransmitter acetylcholine, because he and the researchers thought that regeneration in the [...]

In the face of global climate change, world leaders are in need of models that can reliably predict how land use and other human activities affect atmospheric carbon dioxide levels. Previous modeling studies show that due to warming, the soil releases more carbon dioxide through increased decomposition. But models of the carbon cycle have failed to [...]

DVI (Disaster victim identification ) interventions can be brought to a successful conclusion only if properly planned, involving well-trained key experts and selection of the appropriate forensic diagnostic tools. According to a study presented November 27 at the annual meeting of the Radiological Society of North America, a new, high-tech identification system has been developed in [...]
