Physical environment influences stem cell development
Sep 7, 2010 Science
A researcher at the Hebrew University of Jerusalem, together with Israeli and foreign collaborators, has revealed how physical qualities -- and not only chemical ones - may have an influence in determining how adult stem cells from the bone marrow develop into differentiated ones. This represents...Tags: Adult Stem Cells, Bone Marrow, Collaborators, Environment Influences, Hebrew University Of Jerusalem, Mechanisms, Physical Environment, Physical Qualities, Researcher, Specialization, Stem Cell, Undefined State
NASA’s Magnetospheric Mission Passes Major Milestone
Sep 6, 2010 Science
(PhysOrg.com) -- The universe is still an arcane place that scientists know very little about, but a new NASA Solar Terrestrial Probe mission is going to shed light on one especially mysterious event called magnetic reconnection. It occurs when magnetic lines of force cross, cancel, and reconnect...Tags: Kinetic Energy, Magnetic Energy, Magnetic Lines, Magnetospheric Mission, Milestone, Mysterious Event, Nasa, Particle, Probe Mission, Scientists, Universe

Variations in fine-structure constant suggest laws of physics not the same everywhere
Sep 5, 2010 Science
(PhysOrg.com) -- One of the most controversial questions in cosmology is why the fundamental constants of nature seem fine-tuned for life. One of these fundamental constants is the fine-structure constant, or alpha, which is the coupling constant for the electromagnetic force and equal to about 1...Tags: Billions Of Years, Controversial Questions, Cosmology, Directions, Electromagnetic Force, Fine Structure Constant, Fundamental Constants, Implication, Laws Of Physics, Nature, Neighborhood, Northern Hemisphere, Oxygen, Southern Hemisphere, Tiny Bit, Universe Billions, Variations
‘Slow light’ on a chip holds promise for optical communications
Sep 5, 2010 Science
A tiny optical device built into a silicon chip has achieved the slowest light propagation on a chip to date, reducing the speed of light by a factor of 1,200 in a study reported in Nature Photonics (published online September 5 and in the November print issue).Tags: Light Propagation, Nature Photonics, Optical Communications, Optical Device, Promise, Silicon Chip, Speed Of Light
New self-assembling photovoltaic technology that repairs itself
Sep 5, 2010 Science
Plants are good at doing what scientists and engineers have been struggling to do for decades: converting sunlight into stored energy, and doing so reliably day after day, year after year. Now some MIT scientists have succeeded in mimicking a key aspect of that process.Tags: Decades, New Technology, Plants, Scientists, Sunlight
