New York, March 29 (IANS) After much speculation over its built and specifications over past few months, South Korean giant Samsung on Wednesday launched its flagship device, Galaxy S8, that has a voice assistant. The device comes in two variants with different screen sizes -- the 5.8-inch Galaxy S8 and 6.2-inch Galaxy S8 Plus - and will be available from April 21. Registrations begin from March 30. The device might be priced from $720 (approximately Rs 47,000). Samsung will release these devices in India in the coming months. Samsung also revealed Bixby, a smart voice assistant to rival Apple's Siri and Google's Assistant. With a perfect amalgam of voice, vision and touch, Bixby can search restaurants, take screenshots and even book a cab for you. The technology giant has used the best hardware and provided the best features available to date in the device. The device has a bezel-less curved edge "infinity display" covered with pristine glass and a 12MP rear camera with multi-frame processing and optical image stabilisation. It has an 8MP auto-focus front shooter. The device is IP68 rated, meaning it is water and dust resistant. The company has also upped the security feature with iris scanner, face recognition and fingerprint scanner - moved to the back of the device - to unlock the device. The home button has been shifted beneath the "infinity display". Available in five different colours, the device has a Qualcomm Snapdragon 835 Octa core (2.35 GHz Quad + 1.7 GHZ Quad) processor. For models that will be available in countries other than the US, Samsung has used Exynos Octa core (2.35 GHz Quad + 1.9 GHZ Quad) processor. According to The Verge, while Galaxy S8 comes with a 3,000 mAh battery, the Galaxy S8 Plus is fitted with 3,500 mAh battery pack. The devices run on Android 7.0 Nougat and have USB-C and 3.5mm headphone jacks. The company also launched Samsung Connect app that would allow users to control a number of internet-connected home devices such as TVs or refrigerators. It also unveiled new Gear 360 camera. There's a lot riding on Samsung S8 devices due to the Galaxy Note 7 fiasco. Samsung ultimately killed that smartphone after two recalls, both related to issues with faulty batteries. Earlier this month, Samsung launched two new smartphones in 'Galaxy A' series -- 5.7-inch Galaxy A7 and 5.2-inch Galaxy A5 in India which were priced at Rs 33,490 and Rs 28,990, respectively. Samsung also joined the 'go digital' bandwagon, and last week unveiled Samsung Pay, the company's flagship mobile payments service, in India. At MWC in Barcelona this year, Samsung announced its innovative "I&G (Infill & Growth) Project" for Reliance Jio Infocomm Ltd that will help expand both the current network capacity as well as network coverage.

​New York, March 29 (IANS) Researchers have found why at around the age of four children suddenly do what three-year-olds are unable to do -- put themselves in someone else's shoes.

This enormous developmental step occurs as a critical fibre connection in the brain matures, according to a study published in the journal Nature Communications.

For the study, the research team from Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) in Leipzig, Germany and Leiden University in the Netherlands analysed MRI data and behavioural data of 43 normally developing 3- and 4-year-old children.

"Our findings show that the emergence of mental state representation is related to the maturation of core belief processing regions and their connection to the prefrontal cortex," said the researchers.

The study showed that maturation of fibres of a brain structure called the arcuate fascicle between the ages of three and four years establishes a connection between two critical brain regions.

One region is at the back of the temporal lobe that supports adult thinking about others and their thoughts, and the other is in the frontal lobe that is involved in keeping things at different levels of abstraction and, therefore, helps us to understand what the real world is and what the thoughts of others are. 

Only when these two brain regions are connected through the arcuate fascicle can children start to understand what other people think, the study said.

Interestingly, this new connection in the brain supports this ability independently of other cognitive abilities, such as intelligence, language ability or impulse control, according to the researcher.

​New York, March 29 (IANS) Parents who regularly play "Pokemon GO" with their children report a number of side benefits including increased exercise, more time spent outdoors and opportunities for family bonding, says a study.

Pokemon GO is a location-based augmented reality game in which players capture fictional creatures from the Japanese Pokemon franchise on smartphones and other mobile devices by "finding" them in real-world locations.

"Location-based augmented reality games are pretty different than sitting in front of a TV or playing a typical video game, so we were interested in the way kids and their parents were sharing those experiences together," said lead author Kiley Sobel from University of Washington.

"People still don't really know how to build tech that works well for families, so when this game came out of the blue and really caught on, we wanted to look at what its ingredients for success were," Sobel said.

The results, taken from a qualitative survey of 67 parents and interviews with 20 additional parents playing "Pokémon GO" with their families in the US, are detailed in a paper to be presented at the Association for Computing Machinery's CHI 2017 conference to be held at Denver, Colorado in May.

Some parents said the interactive and mobile nature of the game made them feel better about engaging in that type of gameplay, as opposed to more sedentary forms of "screen time", according to the study.

The study did not include perspectives of parents who do not allow their children to play Pokemon GO. 

Many parents -- particularly moms of boys, fathers of girls and parents of teenaged children -- reported spending more quality time with their children as a result of playing "Pokémon GO" together and talking more than usual, both about the game itself and about other things in their lives, the researchers said.

Parents also appreciated how the game motivated both them and their children to go outside and exercise in ways that were convenient and fit into their lives, as their children displayed newfound enthusiasm for walking the dog or walking rather than driving to dinner or playgrounds. 

For some participants, these "Poké-walks" led to walking thousands more steps per day, the study said.

Shanghai, March 27 (IANS) A China-made wearable robot, which can help disabled people walk, is expected to enter the market in one to two years, the developer has said. The Fourier X1, developed by Chinese technology start-up Fourier Intelligence, was unveiled in Shanghai earlier this month, Xinhua news agency reported. Gu Jie, CEO of Fourier, said the Fourier X1 weighed 20 kg and applied industrial design into the exoskeleton. It can assist with walking for people who have had a stroke or spinal cord injuries. He said the company aimed to make the robot more affordable than foreign models such as Israel-made ReWalk and Japanese-made Cyberdyne currently on the market. Prices of the Fourier X1 robots are expected to be a third cheaper than similar foreign models, which are sold between 600,000 yuan ($87,000) and 1 million yuan ($1,45000) each. Gu said the company was working to test and improve the robot's various functions such as sitting, standing, walking and climbing stairs. The Fourier X1 has four motors, two for the hips and two for the knees, as well as four batteries inside that enable it to work for seven hours. China has 80 million disabled people, many of them unable to walk. The global market for walk-assisting exoskeleton robots is estimated to exceed $1.8 billion by 2020.

Brisbane, March 27 (IANS) A team of palaeontologists has identified 150 tracks from 21 dinosaur species in Australia, the University of Queensland announced on Monday.

The discovery includes five different types of predatory dinosaur tracks, at least six types of tracks from long-necked herbivorous sauropods, four types of tracks from two-legged herbivorous ornithopods, and six types of tracks from armoured dinosaurs, the university said in a press release.

The diversity of the tracks is unparalleled, said Australian paleontologist Steve Salisbury, lead author of the study that was published in the 2016 Memoir of the Society of Vertebrate Paleontology, Efe news reported.

"Among the tracks is the only confirmed evidence for stegosaurus in Australia. There are also some of the largest dinosaur tracks ever recorded. Some of the sauropod tracks are around 1.7 metres long," he said in the statement.

Salisbury called the discovery "extremely significant" as it forms the primary record of non-avian dinosaurs in the western half of the continent and provides the only glimpse of Australia's dinosaur fauna during the first half of the Early Cretaceous Period.

The footprints were found in a rocky area, 127 to 140 million years old, in Walmadany, a region in western Australia containing thousands of dinosaur tracks, and which was listed as a National Heritage in 2011.

The newly-identified 150 tracks are older than most dinosaur fossils unearthed in the eastern part of Australia and which are thought to be between 90 and 115 million years old, added the release.

Members of the aboriginal group Goolarabooloo, traditional inhabitants of Walmadany, approached Salisbury and his team to research the tracks in the region after authorities chose the area to build a liquid natural gas processing plant.

These dinosaur tracks also form part of the Goolarabooloo's songs about Marella, also known as Emu Man, a creator being whose ancient footprints they believe appear and disappear along the coastline.
