Unhealthy diet, sedentary lifestyle may trigger ageing
New York : Poor and unhealthy diet coupled with lack of exercise and a sedentary lifestyle may accelerate the ageing process in humans, warn US researchers.
 
A type of cells called senescent cells contribute to diseases and conditions associated with age. 
 
The researchers found that exercise prevents premature senescent cell accumulation and protects against the damaging effects of an unhealthy diet, including deficiencies in physical, heart and metabolic function.
 
"We think that at both biological and clinical level, poor nutrition choices and inactive lifestyles do accelerate ageing," said senior author Nathan LeBrasseur from Mayo Clinic in the US.
 
In the study, researchers introduced mice to either a normal, healthy diet or a diet that they termed a "fast food diet" -- one that was high in saturated fat and cholesterol along with a sugar-sweetened beverage. 
 
Mice on the fast food diet showed harmful changes in health parameters, including body weight and composition, increasing their fat mass by nearly 300 percent over the course of about four months. 
 
Half the mice, including mice on both the healthy and unhealthy diets, were given exercise wheels.
 
The findings showed mice that had been exposed to the fast food diet but exercised showed suppression in body weight gain and fat mass accumulation and were protected against the accumulation of senescent cells. 
 
"It doesn't mean that we need to be marathon runners but we need to find ways to increase our habitual activity levels to stay healthy and prevent processes that drive ageing and ageing-related diseases," LeBrasseur noted.

Donald Trump speaks like a sixth grader: Study
New York : Republican presidential hopeful Donald Trump may have mesmerised his fans with provocative speeches but researchers have found that in terms of use of words and grammar, he can be compared to a sixth grader.
 
Most presidential candidates in the US are using words and grammar typical of students in grades six to eight, though Donald Trump tends to lag behind the others, the study said.
 
For the study, the researchers at Carnegie Mellon University's Language Technologies Institute (LTI) did a readability analysis of presidential candidate speeches.
 
A historical review of their word and grammar use suggests that all five candidates in the analysis -- Republicans Trump, Ted Cruz and Marco Rubio (who has since suspended his campaign), and Democrats Hillary Clinton and Bernie Sanders -- have been using simpler language as the campaigns have progressed, the researchers said.
 
Again, Trump is an outlier, with his grammar use spiking in his Iowa Caucus concession speech and his word and grammar use plummeting again during his Nevada Caucus victory speech, according to the study.
 
A comparison of the candidates with previous presidents showed president Abraham Lincoln outpacing them all, boasting grammar at the 11th grade level, while president George W. Bush's fifth grade grammar was below even that of Trump.
 
"Assessing the readability of campaign speeches is a little tricky because most measures are geared to the written word, yet text is very different from the spoken word," said one of the researchers Maxine Eskenazi in an official statement.
 
"When we speak, we usually use less structured language with shorter sentences," Eskenazi noted.
 
The researchers used a readability model called REAP, which looks at how often words and grammatical constructs are used at each grade level.
 
Based on vocabulary, campaign trail speeches by past and present presidents -- Lincoln, Reagan, Bill Clinton, George W. Bush and Obama -- were at least on the eighth grade level, while the current candidates ranged from Trump's seventh grade level vocabulary to Sanders' 10th grade level. 
 
In terms of grammar, the current candidates generally had scores between sixth and seventh grades, with Trump just below sixth grade level, the study said.

Bharti Airtel to buy Videocon's spectrum in six circles
New Delhi : Bharti Airtel on Thursday said it will acquire Videocon Telecom's radio frequency spectrum in six circles for Rs.4,428 crore in yet another deal after the government liberalised the trading and sharing of scarce airwaves among operators.
 
"Bharti Airtel has entered into a definitive agreement with Videocon Telecommunications Limited to acquire, at an aggregate consideration of Rs.4,428 crore, the rights to use 2x5 MHz spectrum in the 1,800 MHz Band," the company said in a regulatory filing.
 
The six circles are Bihar, Haryana, Madhya Pradesh, Uttar Pradesh (East), Uttar Pradesh (West) and Gujarat. The spectrum allocation in these circles is valid till December 18, 2032.
 
This deal came a day after Idea Cellular terminated its spectrum trading agreement with Videocon Telecom for its Gujarat and Uttar Pradesh (West) circle. Bharti Airtel's stocks were trading at Rs.348.40 per share in the BSE, up 2.58 percent, at 12.40 p.m.
 
Earlier, Reliance Communications had announced that it has signed a deal for trading and sharing of airwaves with Jio in the 800 MHz band, covering virtually the entire country. A roaming deal was also on the cards.
