New York, April 17 (IANS) Hospitalisation for heart attacks and strokes is less common among people living in areas that restrict trans fats in foods compared to residents in areas without restrictions, new research has found. "Our study highlights the power of public policy to impact the cardiovascular health of a population," said lead author Eric Brandt from Yale School of Medicine in New Haven, Connecticut, US. Trans fatty acids, or trans fats, are commonly found in fried foods, chips, crackers and baked goods. Eating even minimal amounts is linked to a greater risk of cardiovascular disease, the leading cause of death worldwide. Some communities in the US -- most notably New York City -- have eliminated the use of trans fats in restaurants and eateries in recent years. To study the impact of restricting trans fats, researchers compared outcomes for people living in New York counties with and without the restrictions. Using data from the state department of health and census estimates between 2002 and 2013, the researchers focused on hospital admissions for heart attack and stroke. They found that three or more years after the restrictions were implemented, people living in areas with the bans had significantly fewer hospitalizations for heart attack and stroke when compared to similar urban areas where no limits existed. The decline for the combined conditions was 6.2 per cent, said the study published in the journal JAMA Cardiology. "It is a pretty substantial decline," Brandt said. "The results are impressive, given that the study focused on trans fatty acid bans in restaurants, as opposed to complete bans that included food bought in stores," senior author Tamar S. Polonsky, Assistant Professor of Medicine at the University of Chicago, added. "If we enact a more complete restriction on trans fatty acids, it could mean even more widespread benefits for people," Polonsky said.

​Beijing, April 17 (IANS) China's economy got off to a strong start in the first quarter, with the GDP growing at 6.9 per cent year-on-year, according to data released by the National Bureau of Statistics on Monday.

​Tokyo, April 17 (IANS) People who possess a greater understanding of finance tend to accumulate more assets and income during their lifetime, and therefore they are less likely to fret about life in their twilight years, suggests new research.

Beijing, April 17 (IANS) Almost one million foreign nationals worked on the Chinese mainland in 2016, the media reported on Monday.

In the 1980s, less than 10,000 foreigners came to China for work each year, Zhang Jianguo, head of China's State Administration of Foreign Expert Affairs said on Sunday during

​New York, April 17 (IANS) Google is reportedly building an overhauled version of its Google Earth that will be unveiled during an Earth Day event in New York City on April 18, a media report said.

According to a report in Express.co.uk on Monday, Google has sent invitations for an Earth Day-themed event to be held at Whitney Museum of Art in New York City.

Google Earth is a virtual globe that allows users to trawl satellite images of the planet's surface. It uses image resolutions that range between 15m to 15cm. One can search any area on the earth through Google Earth. 

It is assumed that the new version of Google Earth would replace its Google Maps app.

In 2008, Google included its Street View feature that offers a panoramic view from eye-level of streets across the world, in Google Maps.

A dramatically revamped version of Google Earth could bring in more functionality from Google Maps, including traffic reports and local listings, the report said.

​New Delhi, April 16 (IANS) It's best to wear natural fabrics to beat the heat and to keep skin problems at bay, say experts. Vandana Anurag, Founder of The Parisian Boudoir and Salesh Grover, Business Head at OSL Luxury Collections, have shared ways in which you can deal with sweat: * Loose clothes don't touch your body and allow your body to breathe. Believe it or not, but loose fitting apparel like peplum tops, flowy tops or loose pants will always keep you cooler than a pair of skin tight tank and fit denims. * Keep yourself cool by switching to breathable and sweat absorbing fabrics. Always dress up in clothes with natural fabrics it will keep your temperature low. * Avoid wearing dresses with embellishments as they weigh down your clothes and leads the fabric to touch your skin, trapping the body heat. Embellishments also don't let air pass through the fabric, thus causing sweating. * Wearing a light coloured and relaxed fit T-shirt can save you from sweating. They can be played around in different styles. * Summer style is incomplete without chinos and denim shorts. When it comes to shorts, fit and length is the key. You can pair up denim shorts with cotton Polo T-shirt to get the comfort and style.

​New York, April 16 (IANS) Customers who need to replace their fourth generation iPad will now get a newer and more capable iPad Air 2 as a substitute from Apple Stores and authorised service providers, a media report said. Apple is doing this because the company has no stock left of the aging and now discontinued fourth generation iPad, 9to5Mac website reported on Saturday. Apple has also asked its staff to inform customers of the replacement unit's colour and capacity. The iPad Air 2 introduced a new gold colour option, and has 32GB and 128GB storage options while 16GB and 64GB models were discontinued. For that reason, the users may receive a slight upgrade in storage when getting a replacement in addition to the device's newer and more powerful internals overall.

​London, April 16 (IANS) Turning 25? This may be the best time of your life, as according to a study, 25 is the golden age when humans can outsmart computers.

The study showed that people's ability to make random choices or mimic a random process, such as coming up with hypothetical results for a series of coin flips, peaks around age 25.

At their peak, humans outcompete many computer algorithms in generating seemingly random patterns, an ability that arises from some of the most highly developed cognitive processes in humans and may be connected to abilities such as human creativity, the researchers said, in the paper published in the journal PLOS Computational Biology.

"This experiment is a kind of reverse Turing test for random behaviour, a test of strength between algorithms and humans," said Hector Zenil from the Algorithmic Nature Group in France.

"25 is, on average, the golden age when humans best outsmart computers," added Nicolas Gauvrit from the Algorithmic Nature Group.

Previous studies have shown that ageing diminishes a person's ability to behave randomly. However, it had been unclear how this ability evolves over a person's lifetime, nor had it been possible to assess the ways in which humans may behave randomly beyond simple statistical tests.

For the study, the team assessed more than 3,400 people aged four to 91 years old, who were asked to perform a series of online tasks that assessed their ability to behave randomly.

The scientists analysed the participants' choices according to their algorithmic randomness, which is based on the idea that patterns that are more random are harder to summarise mathematically.

After controlling for characteristics such as gender, language, and education, they found that age was the only factor that affected the ability to behave randomly. This ability peaked at age 25, on average, and declined from then on, the researchers noted.

​New York, April 16 (IANS) A team led by an Indian-origin engineer has built a camera prototype that can capture a detailed micron-resolution image from a distance and does that without using a long lens.

The prototype built and tested by engineers at US-based Rice and Northwestern universities uses a laser and techniques borrowed from holography, microscopy and "Matrix"-style bullet time.

It reads a spot illuminated by a laser and captures the "speckle" pattern with a camera sensor. 

Raw data from dozens of camera positions is fed to a computer programme that interprets it and constructs a high-resolution image.

The system known as SAVI -- "Synthetic Apertures for long-range, subdiffraction-limited Visible Imaging" -- only works with coherent illumination sources such as lasers.

"Today, the technology can be applied only to coherent (laser) light," said Ashok Veeraraghavan, a Rice University Assistant Professor of electrical and computer engineering, in a statement.

"That means you cannot apply these techniques to take pictures outdoors and improve resolution for sunlit images -- as yet. Our hope is that one day, maybe a decade from now, we will have that ability," he added.

The technology is the subject of an open-access paper in Science Advances.

Labs led by Veeraraghavan tested the device that compares interference patterns between multiple speckled images.

Veeraraghavan explained the speckles serve as reference beams and essentially replace one of the two beams used to create holograms. 

When a laser illuminates a rough surface, the viewer sees grain-like speckles in the dot. That's because some of the returning light scattered from points on the surface has farther to go and throws the collective wave out of phase. 

SAVI's "synthetic aperture" sidesteps the problem by replacing a long lens with a computer programme that resolves the speckle data into an image. 

"You can capture interference patterns from a fair distance. How far depends on how strong the laser is and how far away you can illuminate," Veeraraghavan added.
