Mobile tower radiation clips sparrows’ wings
Radiation from mobile towers is not only taking a toll on human health but is also blamed for sparrows vanishing into thin air.
An environmental science expert team attributes the disappearance of sparrows to the electromagnetic fields and radiation effects created by mobile towers and mobile phones.
Navigation skills of the birds and earth’s magnetic system are correlated. Natural electromagnetic radiation (EMR) and the earth-oriented magnetic vibration are directly proportional, whereas technology-induced EMR is inversely proportional.
All mobile phone towers emit microwave radiation, which is radio frequency radiation (RFR), part of the spectrum of electromagnetic waves. Long-term exposure to low level RFR has damaging effects on the nervous system and immune system of small animals. Studies indicate that short-term exposure of pulsed mobile phone radiation with carrier frequency 900 MHz reduced the reproductive capacity of insects by 60%.
The environmental science experts suggest regulation of mobile towers in thickly populated areas and restricting them to remote areas. If a tower is installed at a place, another tower should not be permitted within a radius of one kilometer, they say.
Birds are good ecological indicators for low-intensity electromagnetic radiation, they have thin skulls and their feathers can act as dielectric receptors of microwave radiation. Many species use magnetic navigation and microwaves can interfere with their sensors and misguide them while navigating and preying.
According to a survey in 2010, the number of house sparrows (Passerdomesticus) has declined in coastal areas, including Kerala, by 80% and by 2003 the sparrows had almost disappeared from the capital city, Trivandrum.
However, a survey by Travancore Natural History Society in 2012 in Trivandrum had identified about 300 sparrows, mostly around granary stores and market yards.
Various reasons are cited for the disappearance of house sparrows such as introduction of unleaded petrol -- combustion of which produces compounds such as methyl nitrite which is highly toxic for insects that form a major part of young sparrow’s diet --widespread use of garden pesticides, vanishing open grasslands, rising air temperature and modern bird-unfriendly architecture.

Indian Technology to prevent train collisions
Train travel is set to become a lot safer and faster with the railways planning to install an indigenous technology called Train Collision Avoidance System (TCAS) which will help prevent train accidents while enabling the state-run transporter to run more trains on the same track.
The new technology,which could facilitate driverless train operation in future,is the first of its kind in the world and will cost very little.
TCAS is economical and will cost only Rs 10-12 lakh per km to implement.
The system is cheaper and far more effective than the Train Protection Warning System (TPWS) and anticollision device (ACD) which were tried by the railways earlier.
Similar technology used by Delhi Metro costs around Rs 100 crore per km.
TCAS can read signals up to a distance of three km and intimate the driver about the location of signal,station and trains in the area.The information to the engine will be disseminated via radio communication system linking the train to the station and other trains in the vicinity.
The technology will help the driver view the signal from his cabin through a monitor,and also advise the loco pilot on increasing or decreasing train speed depending on location of another train on the same track.
One of its significant features is the availability of an emergency button which the driver can use in the event of a potential mishap,bringing all trains in its vicinity to a halt.In case of any failure on the part of the driver,such as jumping the signal,the station master can also stop the train.
Even if the communication systems installed at stations fail,loco drivers of trains in a 3-km radius will remain in contact.
