Energy from cellphone towers ups pain in amputees: Study
New York : Living near cellphone towers that produce radio-frequency electromagnetic fields can amplify pain in amputees, suggests new research.
 
"Our study provides evidence, for the first time, that subjects exposed to cellphone towers at low, regular levels can actually perceive pain," said senior study author Mario Romero-Ortega, associate professor of bioengineering at University of Texas at Dallas, US.
 
Until this study, published online in the journal PLOS ONE, there was no scientific evidence to back up the anecdotal stories of people, who reported aberrant sensations and neuropathic pain around cellphone towers, the researchers said.
 
"Our study also points to a specific nerve pathway that may contribute to our main finding," Romero-Ortega noted.
 
Most of the research into the possible effects of cellphone towers on humans has been conducted on individuals with no diagnosed, pre-existing conditions. 
 
This is one of the first studies to look at the effects of electromagnetic fields (EMFs) in a nerve-injury model, Romero-Ortega said.
 
The team hypothesised that the formation of neuromas -- inflamed peripheral nerve bundles that often form due to injury -- created an environment that may be sensitive to EMF-tissue interactions. 
 
To test this, the team randomly assigned 20 rats into two groups -- one receiving a nerve injury that simulated amputation, and the other group receiving a sham treatment.
 
Researchers then exposed the rats to a radiofrequency electromagnetic antenna for 10 minutes, once per week for eight weeks. 
 
The antenna delivered a power density equal to that measured at 39 meters from a local cellphone tower.
 
Researchers found that by the fourth week, 88 percent of rats in the nerve-injured group demonstrated a behavioural pain response, while only one rat in the other group exhibited pain at a single time point, and that was during the first week. 
 
"Our model found that electromagnetic fields evoked pain that is perceived before neuroma formation; subjects felt pain almost immediately," Romero-Ortega said. 
 
The researchers believe that the protein TRPV4, which is known to be a factor in heat sensitivity, could be a mediator in the pain response for these rats.

Nursery admissions: HC restores management quota
New Delhi : The Delhi High Court on Thursday restored the management quota in private unaided schools in the national capital for nursery admissions.
 
Justice Manmohan in an interim order stayed the January 6 circular of the Aam Aadmi Party government that scrapped 62 criteria, including the management quota.
 
The court said the Delhi government order was passed without any authority - without approval of Lieutenant Governor Najeeb Jung.

Cabinet note by month-end on scrapping old vehicles: Gadkari
Greater Noida : The central government will soon consider a policy to phase out old vehicles from public roads, Minister of Road Transport and Highways Nitin Gadkari said on Thursday.
 
"A note on scrapping of old vehicles is being put up for the Cabinet's consideration by the end of the month," Gadkari said in his address at the inauguration of Auto Expo 2016 here.
 
On scrapping of old polluting vehicles, the minister had earlier proposed that owners could be given an incentive of up to Rs.30,000 for discarding small vehicles like cars.
 
A ministry source here told IANS that in view of the union budget coming up later this month, Gadkari has written to Finance Minister Arun Jaitley that the budget should offer an excise rebate for new cars bought in exchange of a 15-year old car.
 
The source said an "end of life" policy may be announced in the budget that may include a rebate of 50 percent in excise duty on new vehicles for buyers who surrender their old ones.
 
The road ministry has also requested that accelerated depreciation of up to 50 per cent may be given to auto industry on additional investment for bringing environment-friendly vehicles.
 
In this regard, Gadkari said that after consulting the concerned ministries, the government has taken the decision to make mandatory the Euro 6 fuel emission norms for vehicles from April 1, 2020.
 
He said the availability of the required fuel would not be a problem, as assured by the union petroleum minister.
 
"Invest in electric vehicles and on R&D (research and development) in battery technology," Gadkari told auto industry representatives at the gathering, exhorting them to contribute their efforts towards pollution control.

Old vehicles aged more than 15 years should be faced out may be within next 2/3 years not only as a matter of environment protection against pollution but as a matter of safety on road with the present day speed & carrying capacity etc. No duty concession or any other rebates are necessary as these are luxury items and only those who can afford buy vehicles either for comfortable travel or business. Let the scraped vehicles be withdrawn & crushed beyond use & send for recycling. This should be applicable to 2 wheelers also.
