Researchers have recently developed a cognitive test battery, dubbed as Cognition, to measure the impact of typical spaceflight stressors like microgravity, radiation, confinement and isolation, exposure to elevated levels of CO2, and sleep loss) on cognitive performance of astronauts.
With the health and safety aspects of using mobile phones and the radiation from its towers being a cause of concern for many, experts feel that reducing the energy transmitted per bit and adopting some precautionary measures can help in the long run.
Cellular Operators Association of India, the apex body of mobile communications companies, today said the Electro Magnetic Field (EMF) emissions from antennae on cell towers and mobile handsets do not cause any health hazards.
A series of studies on the biological impact of the Fukushima disaster on non-human organisms has revealed that the radiation has affected the population, genetic makeup and the repair mechanisms of birds, monkeys, butterflies, and other insects to cope with the exposure.
Researchers have measured the minute gravitational distortions in polarized radiation from the early universe and discovered that these ancient microwaves can provide a cosmological test of Einstein`s theory of general relativity.
Scientists have claimed that rats exposed to high-energy particles, simulating conditions that astronauts would face on a long-term deep space mission, show lapses in attention and slower reaction times, even when the radiation exposure is extremely low.
