redOrbit Staff & Wire Reports - Your Universe Online A new study of stem cells derived from skin tissue has challenged the commonly held notion that a person's cells all share the same DNA sequence, arguing instead that genetic variation may occur to a greater extent than experts had previously believed. Researchers at the Yale School of Medicine set out to challenge the theory that human cells are comprised of identical genetic material, and that a body's functions are governed by...

Infants born prematurely and with hypoxia--inadequate oxygen to the blood--are able to recover some cells, volume and weight in the brain after oxygen supply is restored, Yale School of Medicine researchers report in Experimental Neurology. Working with mice reared in a low-oxygen environment from three to 11 days after birth, the researchers found that about 30 percent of the cortical neurons were lost from the injury. But this damage was transient. The lost cortical neuron number, volume...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
