DENGUE time bomb ticks with the onset of monsoon !

['Travel, urbanisation have led to 50-fold rise in DENGUE cases']


Constant travelling and rapid urbanisation of rural areas have contributed to a nearly 50-fold increase in dengue cases over the last 50 years, say experts.
Aedes aegypti was known to be the vector of urban areas and Aedes albopictus was responsible for the disease in rural and suburban areas. However, in recent times this division has blurred, because people move about a lot these days. This has led to a nearly 50-fold increase in dengue cases," study of  the School of Tropical Medicine in Kolkata  reveals.
According to the World Health Organisation (WHO), over 2.5 billion people - more than 40 percent of the world's population - are now at risk from dengue, which is a viral disease spread by mosquitoes of the genus Aedes, principally A. aegypti.
WHO currently estimates there may be 50-100 million dengue infections worldwide every year. In West Bengal such outbreaks occurred at intervals of 18 to 20 yea…

Now mobile phone jammers to minimise road accidents !

Mobile phones may have brought instant communication within the reach of all, but they are also fast turning into a global killer, accounting for 20 percent of fatal road accidents worldwide annually, half of which are on Indian highways alone.
Pioneering new technology, developed by Abdul Shabeer, doctoral scholar at Anna University of Technology, Coimbatore, and his colleagues R.S.D. Wahidabanu and H. Abdul Zubar, will jam mobile phones that truckers use on their long distance hauls and so prevent accidents.
"Lorry and heavy vehicle operators seldom keep their mobile phones switched off during such trips, but the distracting nature of the device, especially dialling a number, talking on the phone or just holding a phone while driving can be an immediate hazard on roads, Shabeer told.
The jamming system operates whenever the driver turns on the ignition. The jamming device receives radiation emitted by the phone. The device can tell whether the mobile phone is being used by the…
