PHILADELPHIA ?- Physicists, chemists and engineers at the University of Pennsylvania have demonstrated a novel method for the controlled formation of patchy particles, using charged, self-assembling molecules that may one day serve as drug-delivery vehicles to combat disease and perhaps be used in small batteries that store and release charge.
La Jolla, CA -- October 18, 2009 -- Fate Therapeutics, Inc. announced today the generation of human induced-pluripotent stem cells (iPSCs) using a combination of small molecules that significantly improves the speed and efficiency of reprogramming. The discoveries, which were made by Sheng Ding, Ph.D.
LA JOLLA, CA -- October 15, 2009 A team led by scientists from The Scripps Research Institute has developed a method that dramatically improves the efficiency of creating stem cells from human adult tissue, without the use of embryonic cells. The research makes great strides in addressing a major practical challenge in the development of stem-cell-based medicine.
Neuroscience researchers from the Yerkes National Primate Research Center, Emory University, will present a wide range of research topics at the Society for Neuroscience's 39th annual meeting in Chicago, Oct. 17-21, 2009. The information below is a representation of the neuroscience research Yerkes scientists will be discussing.
Direct communication between Earth and Mars can be strongly disturbed and even blocked by the Sun for weeks at a time, cutting off any future human mission to the Red Planet. An ESA engineer working with engineers in the UK may have found a solution using a new type of orbit combined with continuous-thrust ion propulsion.
What is reality?
You may say, ‘All that is real, is reality.’ And, by the word ‘real’, I understand, all that can be seen, felt or heard. So, for example, if I see a flower in front of me, then it is obviously real. No one can seriously doubt that fact! No one can seriously say that the flower is not ‘real’.
Really?
The perception that antibiotic resistance is primarily the undesirable consequence of antibiotic abuse or misuse is a view that is simplistic and inaccurate, according to a recent report by the American Academy of Microbiology.
The National Science Foundation (NSF) congratulates the 2009 Nobel laureates, particularly those who have received NSF funding over the years: Jack W. Szostak, who shared the prize in physiology or medicine; Thomas A. Steitz, who shared the prize in chemistry; and Elinor Ostrom and Oliver E.
When Professor Joel Levine's team genetically tweaked fruit flies so that they didn't produce certain pheromones, they triggered a sexual tsunami in their University of Toronto Mississauga laboratory.
LA JOLLA, CA -- Although the human genome sequence faithfully lists (almost) every single DNA base of the roughly 3 billion bases that make up a human genome, it doesn't tell biologists much about how its function is regulated.
Plants may not have eyes and ears, but they can recognize their siblings, and researchers at the University of Delaware have discovered how.
The ID system lies in the roots and the chemical cues they secrete.
The finding not only sheds light on the intriguing sensing system in plants, but also may have implications for agriculture and even home gardening.
Each of the 6.7 billion people on Earth has a signature body odor -- the chemical counterpart to fingerprints -- and scientists are tracking down those odiferous arches, loops, and whorls in the "human odorprint" for purposes ranging from disease diagnosis to crime prevention.
Oct. 13, 2009 -- Ever wonder how your eyes adjust during a blackout? When we go from light to near total darkness, cells in the retina must quickly adjust. Vision scientists at Washington University School of Medicine in St. Louis have identified an intricate process that allows the human eye to adapt to darkness very quickly.
MADISON, WI, OCTOBER 12, 2009 -- Areas of turf-forming species created and maintained by humans for aesthetic and recreational (not grazing) purposes, i.e. "urban grasslands" are an extremely common, but poorly studied ecosystem type. There are over 150,000 km2of urban grasslands in the U.S.
In an effort to make graphene more useful in electronics applications, Kansas State University engineers made a golden discovery -- gold "snowflakes" on graphene.
