​New York, March 9 (IANS) In a bid to make 360 degree photos and videos more immersive and easier to discover, Facebook has launched a new virtual reality app called "Facebook 360" for Samsung Gear VR headset which is powered by Oculus.

​New York, March 9 (IANS) US tech giant Google has confirmed the acquisition of Australia-born data science community Kaggle for an undisclosed sum.

The confirmation came at the Google's "Cloud Next" conference in San Francisco late on Wednesday.

​New York, March 9 (IANS) After The New York Times, The Guardian and some other leading media organisations, CNN has officially launched "CNNVR" -- a new immersive journalism unit and virtual reality platform.

Beijing, March 9 (IANS) China aims to create 11 million new jobs for urban residents this year, despite the slowdown of economic growth, a media report said on Thursday.

The confident move, according to analysts, is because the country has maintained a medium-to-high speed of economic growth, the People's Daily said in the report.

​New York, March 9 (IANS) San Francisco-based Pinterest has acquired Twitter co-founder Biz Stone's "human powered" search engine start-up Jelly.

"This is the best decision for the future of human powered search and discovery. Jelly plus Pinterest is an exceedingly powerful match. A new adventure begins!" Stone, Co-

San Francisco, March 9 (IANS) Google on Thursday announced a strategic partnership with European multinational software corporation SAP to develop and integrate Googles best cloud and machine learning solutions into SAP enterprise applications.

​San Francisco, March 9 (IANS) Global average internet connection speed has increased 12 per cent to 7.0 Mbps in the fourth quarter of 2016 -- a 26 per cent increase year-over-year, a new report said on Thursday.

​Canberra, March 9 (IANS) Neanderthals have been revealed to have had complex vegetarian diets, while some also used plant-based medicines to treat illnesses, an Australian research revealed on Thursday.

Often thought of by many as simple "cave men" with only weak links to modern humans, Laura Weyrich from the Australian Centre for Ancient DNA has said analysis of Neanderthal dental plaque has revealed a varied and "modern-looking" vegetarian diet, Xinhua news agency reported.

"It's a very, very different picture from the grunting, club-toting Neanderthal that we like to think about," Weyrich told the Australian Broadcasting Corporation (ABC) on Thursday.

"They were probably very intelligent, communicative and very in tune with what was going on around them."

Weyrich revealed that some families of Neanderthal, such as the El Sidron group from modern Spain, ate a diet comprised mostly of plants and vegetables available in the forest.

She said there was evidence of pine nuts, mushrooms, grass and moss in the plaque analysis from the El Sidron Neanderthals.

"So that's the true palaeo diet," Weyrich said. "That's what people would have been eating in palaeolithic times if they lived in a forest like the El Sidron Neanderthal did."

In addition, Weyrich said the research uncovered evidence that Neanderthals used specific plants to try and treat a variety of illnesses, including using poplar bark - which happens to contain an active ingredient in Penicillium and aspirin - to counter the effects of gastrointestinal issues such as diarrhoea.

"So it is likely he would have been trying to self-medicate," Weyrich added.

​Washington, March 9 (IANS) NASA's planet-hunting Kepler space telescope was hit by a cosmic ray event during a recent campaign to observe TRAPPIST-1, a star system that hosts at least seven Earth-sized planets only 40 light-years away.

"During Campaign 12, a cosmic ray event reset the spacecraft's onboard software causing a five-day break in science data collection," NASA said in a statement on Wednesday.

"The benign event is the fourth occurrence of cosmic ray susceptibility since launch in March 2009. The spacecraft remains healthy and is operating nominally," the US space agency added while announcing the release of the data Kepler gathered about TRAPPIST-1.

On February 22, astronomers announced that the ultra-cool dwarf star, TRAPPIST-1, hosts a total of seven Earth-size planets that are likely rocky, a discovery made by NASA's Spitzer Space Telescope in combination with ground-based telescopes. 

Kepler space telescope also has been observing this star since December 2016. 

During the period of December 15, 2016 to March 4, the Kepler spacecraft, operating as the K2 mission, collected data on the star's minuscule changes in brightness due to transiting planets. 

These additional observations are expected to allow astronomers to refine the previous measurements of six planets, pin down the orbital period and mass of the seventh and farthest planet, TRAPPIST-1h, and learn more about the magnetic activity of the host star.

"Scientists and enthusiasts around the world are invested in learning everything they can about these Earth-size worlds," said Geert Barentsen, K2 research scientist at NASA's Ames Research Center at Moffett Field, California. 

"Providing the K2 raw data as quickly as possible was a priority to give investigators an early look so they could best define their follow-up research plans. We're thrilled that this will also allow the public to witness the process of discovery," Barentsen said.

The release of the raw, uncalibrated data collected will aid astronomers in preparing proposals due this month to use telescopes on Earth next winter to further investigate TRAPPIST-1, NASA said.

New York, March 9 (IANS) The preliminary results of an experiment confirm what the 2015 Hollywood science fiction film "The Martian" showed: potatoes can grow on Mars.

The International Potato Centre (CIP) in Lima, Peru, launched a series of experiments to discover if potatoes can grow under Mars atmospheric conditions and thereby prove they are also able to grow in extreme climates on Earth. 

The new phase of CIP's experiment to grow potatoes in simulated Martian conditions began on February 14 last year.

Based upon designs and advice provided by the NASA's Ames Research Centre in California, a tuber was planted in a specially constructed CubeSat contained environment built by engineers from the University of Engineering and Technology (UTEC) in Lima.

"If the crops can tolerate the extreme conditions that we are exposing them to in our CubeSat, they have a good chance to grow on Mars. We will do several rounds of experiments to find out which potato varieties do best," said Julio Valdivia-Silva from UTEC. 

"We want to know what the minimum conditions are that a potato needs to survive," he said in a statement released by CIP.

The CubeSat houses a container holding soil and the tuber. Inside this hermetically sealed environment, the CubeSat delivers nutrient-rich water, controls the temperature for Mars day and night conditions, and mimics Mars air pressure, oxygen and carbon dioxide levels. 

Live streaming cameras recording the soil showed potato sprouting in the simulated Martian conditions.

The results so far have been positive, the researchers said.
