Life's origins were easier than was thought

...imately 70 bases long. The discovery has greatly relaxed the conditions necessary for the first living organisms to develop. "This quantity of genes would be enough for a simple organism to have enough functional activity", according to the researchers. Recent analysis into the minimum number of DNA genes ...

Chernobyl: The true scale of the accident

...ting "zoning" definitions need to be revisited and relaxed in light of the new findings. * About 4,000 cases of thyroid cancer, mainly in children and adolescents at the time of the accident, have resulted from the accident's contamination and at least nine children died of thyroid cancer; however the s...

Brain regions do not communicate efficiently in adults with autism

...of 124 electrodes while the people were seated and relaxed with their eyes closed for two minutes. The researchers found patterns of higher than normal neural connectivity in the left hemisphere, particularly in the temporal lobe of the persons with autism within two different frequencies of brain waves...

Slow brain waves play key role in coordinating complex activity

... Brain waves - such as the slow alpha waves of the relaxed or idling brain or the fast, seemingly random pulses accompanying dream sleep - are generated by coordinated firing of neurons in the brain triggered by waves of excitability that wash over an area. Waves of excitability in the theta range of oscilla...
