August 9, 2017: Researchers, led by one of the Indian-origin, have developed a new device that can non-invasively convert skin cells into elements of any organ with a single touch, a finding that may help repair injured tissues, blood vessels, and nerves.The device called Tissue Nanotransfection (TNT) does not require any laboratory-based procedures and may be implemented at the point of care.
It instantly delivers new DNA or RNA into living skin cells to change their function, with a small electrical charge that’s barely felt by the patient, thus aiding the speedy repair of injured tissue as well as restoring the function of ageing tissue, including organs.
“With this nano chip technology, we can convert skin cells into elements of any organ with just one touch. This process only takes less than a second and is non-invasive, and then you’re off. The chip does not stay with you, and the reprogramming of the cell starts,” said Chandan Sen, Director at The Ohio State University in the US.
For the study, published in the journal Nature Nanotechnology, the team conducted experiments on mice and pigs, where they reprogrammed skin cells to become vascular cells in badly injured legs that lacked blood flow. Within one week, active blood vessels appeared on the injured leg and by the second week, the leg was saved.
In lab tests, the technology was also shown to reprogram skin cells in the live body into nerve cells that were injected into brain-injured mice to help them recover from the stroke, the researchers said.
“This is difficult to imagine, but it is achievable, successfully working about 98 per cent of the time,” Sen said, adding the researchers plan to start clinical trials next year in humans. (IANS)
Washington, October 8, 2017 : Most Americans believe their jobs are safe from the spread of robots and automation, at least during their lifetimes, and only a handful says automation has cost them a job or loss of income.
Still, a survey by the Pew Research Center also found widespread anxiety about the general impact of technological change. Three-quarters of Americans say it is at least “somewhat realistic” that robots and computers will eventually perform most of the jobs currently done by people. Roughly the same proportion worry that such an outcome will have negative consequences, such as worsening inequality.
“The public expects a number of different jobs and occupations to be replaced by technology in the coming decades, but few think their own job is heading in that direction,” Aaron Smith, associate director at the Pew Research Center, said.
The Pew Research Center in Washington, D.C. on July 6, 2005, is the author of a 2017 study looking at the spread of automation and robotics in the workplace.
More than half of respondents expect that fast food workers, insurance claims processors and legal clerks will be mostly replaced by robots and computers during their lifetimes. Nearly two-thirds think that most retailers will be fully automated in 20 years, with little or no human interaction between customers and employers.
Americans’ relative optimism about their own jobs might be the more accurate assessment. Many recent expert analyses are finding less dramatic impacts from automation than studies from several years ago that suggested up to half of jobs could be automated.
Skills will need to be updated
A report issued by the education company Pearson, Oxford University, and the Nesta Foundation found that just one in five workers are in occupations that will shrink by 2030.
Many analysts increasingly focus on the impact of automation on specific tasks, rather than entire jobs. A report in January from the consulting firm McKinsey concluded that less than 5 percent of occupations were likely to be entirely automated. But it also found that in 60 percent of occupations, workers could see roughly one-third of their tasks automated.
That suggests workers will need to continually upgrade their skills as existing jobs evolve with new technologies.
Few have lost jobs to automation
Just 6 percent of the respondents to the Pew survey said that they themselves have either lost a job or seen their hours or incomes cut because of automation. Perhaps not surprisingly, they have a much more negative view of technology’s impact on work. Nearly half of those respondents say that technology has actually made it harder for them to advance in their careers.
Contrary to the stereotype of older workers unable to keep up with new technology, younger workers — aged 18 through 24 — were the most likely to say that the coming of robots and automation had cost them a job or income. Eleven percent of workers in that group said automation had cut their pay or work hours. That’s double the proportion of workers aged 50 through 64 who said the same.
The Pew survey also found widespread skepticism about the benefits of many emerging technologies, with most Americans saying they would not ride in a driverless car. A majority are also not interested in using robots as caregiver for elderly relatives.
Thirty percent of respondents said they think self-driving cars would actually cause traffic accidents to increase, and 31 percent said they would stay roughly the same. Just 39 percent said they thought accidents would decline.
More than 80 percent support the idea of requiring self-driving cars to stay in specific lanes.
The survey was conducted in May and had 4,135 respondents, Pew said. (VOA)
Legendary Indian film actor and Padma Shri awardee Aparna Sen will be in Chicago this week. She is synonymous with bringing Bengali cinema closer to the masses not just in India but globally too finds an artistic proximity to Chicago. She says that the architecture of the city reminds her of a studio set from a movie.
Currently in the US, Sen has been having a very hectic schedule as her latest directorial venture, Sonata, is all set to be screened at film festivals in the US.
Amidst her busy schedule Aparna Sen takes out some time to talk to
Hi India! about her creative pursuits, the scope of regional Indian cinema in the US and of course about her love for museums and eateries in Chicago
“I have been to Chicago twice before this, and I’ve enjoyed the city hugely both times. I particularly like the downtown area with its interesting art deco architecture, its museums and eateries.” – Aparna Sen
Sen who has also directed critically acclaimed films such as 36 Chowringee Lane, that won her Best Director Award at the Indian National Film Awards is looking forward to the screening of her recent directorial film Sonata in America
Aparna Sen will be in the city to attend the 8th edition of Chicago South Asian Film Festival and is appreciative of the interest alternate Indian films have been creating in the US.
New Delhi, Sep 22, 2017: India has progressed better than US and China in terms of its specialist doctors adopting digital modes to interact with patients and prescribe medicines, a study revealed on Friday.
According to the study, gap in US between the face-to-face medicines and medical representatives triggered mails narrowed down from 15 per cent in 2015 to 12 per cent in 2017. The study stated that digital channels are slowly but surely gaining ground over traditional ones. This year, the gap further narrowed to around 12 per cent.
“India witnessed the narrowing of the gap between face-to-face tablet and medical representatives triggered mail from 34 per cent in 2015 to 8 per cent in 2017,” said the study conducted by Indegene — a company offering research and development solutions to healthcare and pharmaceutical enterprises.
The highest number of specialist who have adopted digital platform to deal with patients are Cardiologists, General Surgeons, Pulmonologists, Endocrinologists, and Oncologists.
