Study: Living coral reefs provide better protection from tsunami waves
Healthy coral reefs provide their adjacent coasts with substantially more protection from destructive tsunami waves than do unhealthy or dead reefs, a Princeton University study suggests. Initially spurred by the tsunami that devastated the coastlines of the Indian Ocean two years ago, a team of scientists developed the first-ever computer model of a tsunami strike against a reef-bounded...Slow brain waves play key role in coordinating complex activity
While it is widely accepted that the output of nerve cells carries information between regions of the brain, it's a big mystery how widely separated regions of the cortex involving billions of cells are linked together to coordinate complex activity. A new study by neuroscientists at the University of California, Berkeley, and neurosurgeons and neurologists at UC San Francisco (UCSF) is be...T-waves to sweep over imaging technology
The 230th national meeting of the American Chemical Society in Washington will focus on T-rays that offer the potential to see biological agents through a sealed envelope and detect tumors without harmful radiation. T-rays are opening the door to a wide variety of // applications and are based on the terahertz (THz) region of the electromagnetic spectrum -- defined by frequencies from...Heat Avoidance Advice Insufficient During Heat Waves
The passive dissemination of advice on heat avoidance is insufficient for health protection during a heat wave, and vulnerable people need to be actively identified and cared// for, argues a public health expert in this week’s BMJ. This summer Europe has again been affected by a major heat wave, writes Sari Kovats of the London School of Hygiene and Tropical Medicine. The UK has recen...Slow brain waves integral in coordination of complex activity
Berkeley – It is well known that the output of nerve cells is the messenger of information between regions of the brain, //yet it is still unclear about how widely separated regions of the cortex involving billions of cells come together to assist a complex activity. A new study by neuroscientists at the University of California, Berkeley, and neurosurgeons and neurologists at UC San Fran...Global Warming Spurring Ocean Waves Speed
Global warming is speeding up ocean waves, a new study by Canadian researchers from the University of Victoria in British Columbia, has found. Geophysicists predict that as the ocean surface warms, these so-called planetary waves should speed up. To test this theory, John Fyfe and Oleg Saenko modelled the changes to ocean wave patterns over the 20th and 21st centuries...
