From next year, keep your mobile number when you change operatorSeptember 23rd, 2009 NEW DELHI - India's telecom regulator Wednesday issued guidelines on mobile number portability (MNP) that will allow subscribers to change operators while retaining the original number, but only within a particular circle. The new facility will become a reality from Dec 31 in metros and by March 20, 2010 in the rest of the country, said a statement from the Telecom Regulatory Authority of India.
Climate change will lead to less ultraviolet radiation over northern high latitudesSeptember 16th, 2009 TORONTO - A new study by University of Toronto (U of T) physicists has shown that climate change will lead to less ultraviolet radiation over northern high latitudes. They discovered that changes in the Earth's ozone layer due to climate change will reduce the amount of ultraviolet (UV) radiation in northern high latitude regions such as Siberia, Scandinavia and northern Canada.
Ozone layer changes may increase UV radiation in tropicsSeptember 16th, 2009 TORONTO - Ozone layer alterations, prompted by climate change, will enhance ultraviolet (UV) radiation in the tropics and Antarctica, according to a discovery by physicists. Climate change is an established fact, but scientists are only just beginning to understand its regional manifestations, said Michaela Hegglin, a physics researcher at the University of Toronto (U-T) and lead study author.
New transient radiation belt discovered at SaturnSeptember 14th, 2009 LONDON - Scientists, using the Cassini spacecraft's Magnetospheric Imaging instrument (MIMI), have detected a new, temporary radiation belt at Saturn, located around the orbit of its moon Dione at about 377,000 km from the centre of the planet. Radiation belts, like Earth's Van Allen belts, have been discovered at Jupiter, Saturn, Uranus and Neptune.
New clues may help solve Saturn's rotation mysterySeptember 10th, 2009 WASHINGTON - A team of scientists has found new clues that could help solve Saturn's rotation mystery. Scientists have known for some time that Saturn emits intense kilometer-wavelength radio emission, known as Saturn kilometric radiation (SKR), which rotates with a period of 10.8 hours.
Scientists propose new way to reproduce a black hole in the labAugust 22nd, 2009 WASHINGTON - In a new research, a team of scientists at Dartmouth university has proposed a new way of creating a reproduction black hole in the laboratory on a much-tinier scale than their celestial counterparts. The new method to create a tiny quantum sized black hole would allow researchers to better understand what physicist Stephen Hawking proposed more than 35 years ago: black holes are not totally void of activity; they emit photons, which is now known as Hawking radiation.
Plants under stress emit more methane, worsen global warmingAugust 18th, 2009 TORONTO - Methane emission by plants in dry or drought prone areas could aggravate global warming more than previously suspected, says a new study. A University of Calgary (U-C) study warns that plants exposed to environmental factors -- rising temperature, drought and ultraviolet-B radiation -- show enhanced methane emissions.
Stressed crops emit more methane emissions than previously thoughtAugust 18th, 2009 WASHINGTON - Scientists at the University of Calgary (U of C) in Canada have found that methane emission by stressed crops could be a bigger problem in global warming than previously thought. According to a U of C study, when crops are exposed to environmental factors that are part of climate change - increased temperature, drought and ultraviolet-B radiation - some plants show enhanced methane emissions.
Radiation from massive stars may trigger many more stars than previously thoughtAugust 13th, 2009 WASHINGTON - A new study from two of NASA's Great Observatories has shown that radiation from massive stars may trigger the formation of many more stars than previously thought. While astronomers have long understood that stars and planets form from the collapse of a cloud of gas, the question of the main causes of this process has remained open.
Martian dust storms can generate lightningAugust 9th, 2009 WASHINGTON - Scientists, using a new detector, have for the first time observed evidence that Martian dust storms can generate lightning. Dust storms on Earth build up an electric field as dust particles collide, and then emit lightning as the electric field discharges.
Solar radiation caused periodic ice ages to end 19,000 years agoAugust 7th, 2009 WASHINGTON - In a new research, scientists have concluded that slight shifts in solar radiation caused by predictable changes in Earth's rotation and axis made the periodic ice ages to finally come to an end about 19,000 years ago. The research, by scientists from Oregon State University and other institutions conclude that the known wobbles in Earth's rotation caused global ice levels to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.
Mobile addicts 'have slower minds, make more mistakes'August 5th, 2009 MELBOURNE - Heavy mobile phone users have poorer memory, slower reaction times and make more mistakes, a new study has found. The study by researchers from Monash University reviewed 300 students aged 12 to 14 from 20 Melbourne private and state schools.
Punjab Police embrace mobilesJuly 31st, 2009 CHANDIGARH - All field officials of the Punjab Police are to get mobile telephones to improve their connectivity and response time. The telephones will be given to all police officers and non-gazetted officers posted in the field, a police department spokesman said Friday.
Study: Tanning beds and UV radiation as deadly as arsenic, mustard gas, experts sayJuly 29th, 2009 Study: Tanning beds as deadly as arsenicLONDON — International cancer experts have moved tanning beds and other sources of ultraviolet radiation into the top cancer risk category, deeming them as deadly as arsenic and mustard gas. For years, scientists have described tanning beds and ultraviolet radiation as "probable carcinogens."
A new analysis of about 20 studies concludes the risk of skin cancer jumps by 75 percent when people start using tanning beds before age 30.
Study: Tanning beds and UV radiation definitely cause cancer experts sayJuly 29th, 2009 Study: Tanning beds definitely cause cancerLONDON — International cancer experts have moved tanning beds and ultraviolet radiation into the top cancer risk category deeming both to be definite causes of cancer. For years, scientists have described tanning beds and ultraviolet radiation as "probable carcinogens."
A new analysis of about 20 studies concludes the risk of skin cancer jumps by 75 percent when people start using tanning beds before age 30.
