Forget facial recognition technology or fingerprint computer identification as researchers have developed a computer security system using the dimensions of the heart as identifier. "No two people with identical hearts have ever been found," said the study's lead author Wenyao Xu, Assistant Professor at the University at Buffalo in New York. And people's hearts do not change shape, unless they suffer from serious heart disease, he said. The system, which may eventually be used for smartphones and at airport screening barricades, is a safe and potentially more effective alternative to passwords and other biometric identifiers, the researchers said. "We would like to use it for every computer because everyone needs privacy," Xu said. "Logging-in and logging-out are tedious," he said. To make sure no one else steps in to run your computer, the system uses low-level Doppler radar to measure your heart, and then continually monitors yo...

Researchers find that a fungal biomass does the job Removing hexavalent chromium from industrial effluents, particularly untreated tannery waste, will become easier and more efficient thanks to the work by a team of researchers from the Indian Institute of Chemical Biology (CSIR-IICB), Kolkata. Importantly, the heat-dried fungal biomass converts Cr(VI) — which is neurotoxic, genotoxic and a carcinogen — to a non-toxic trivalent form of chromium, thus eliminating the problems of disposing Cr(VI)-containing waste. Cr(VI) is found in very high concentration in tannery waste. The results were published in the journal,  Scientific Reports. A team led by Sucheta Tripathy from the Structural Biology and Bio-Informatics Division at IICB isolated a fungus,  Arthrinium malaysianum , and used the fungus biomass to remove Cr(VI). In experiments carried out in the lab using potassium dichromate solution, the adsorption capacity of the biomass was found to be as high as over 100 mg per...

Law and IT Minister Ravi Shankar Prasad today said that 95 mobile manufacturing companies have set up their plants under the new government. “Today 95 mobile manufacturing factories have come in India and India is becoming a big hub of electronics and mobile manufacturing. 32 have come in Noida and Greater Noida,” Mr. Prasad said at Capital Foundation Annual Lecture. He was speaking on ‘Emerging Digital World In India’. “In Silicon Valley 51% of new inventions are IT based and 14% of those are created by Indian minds there. That is how India is emerging,” Mr. Prasad said. He said that young entrepreneurs are growing their businesses and raising hundreds of millions from investors. “Every day we are adding 3-4 start-ups. They are IITians, they left their jobs in America and come back to India,” Mr. Prasad said. The minister complimented the Supreme Court for leveraging digital technology in expediting judicial processes. “We have created digital data grid. Today we h...

As more people (sometimes grudgingly) shift to watching content from small screens to even smaller ones — video producers and device manufacturers are pushing to create a more immersive on-the-go experience Watching a fellow commuter watch  World War Z  on his phone, (sounds like Joseph Heller looking at Rembrandt’s painting of Aristotle contemplating the bust of Homer) I thought I would never ever watch content on my phone. What is the fun of watching zombies bring a chopper down on a tiny little screen? When film editor Arindam Ghatak ( Rocket Singh, Go Goa Gone ) posted on Facebook that his mother was on a movie-watching spree as she recovered from a cerebral stroke, I was intrigued. “Now she spends most of her waking hours pouring over her phone watching classics on YouTube,” Arindam wrote. “Ray would have been horrified. So would a lot of us, at the very thought of watching entire films on a little smartphone. But she is so full of joy when she sits to watch her film...

Publisher: Capcom Price: ₹2499 on PlayStation 4, ₹3,999 on Xbox One It's going to be hard not to compare the latest Marvel vs. Capcom: Infinite game with DC's successful Injustice 2, which launched earlier this year. Both are fighting games, and both are based on successful comic books and comic book movies. While Injustice has been around for a few years, Marvel vs. Capcom has a pedigree, coming from a long line of games starting way back with X-Men vs Street Fighter and now culminating in the latest Marvel vs. Capcom: Infinite. It’s the crossover of our dreams where characters from Capcom's roster of games meet Marvel's superheroes and villains in an all out fireworks display of action. What's it about? Ultron, the villain from the last  Avengers movie is back and this time he's quite literally, joined forces with Sigma, the main bad guy from the Mega Man series. They’re fused into Ultron Sigma, a robotic super being that brings together two un...

Researchers in Mumbai have moved a step closer to treating surface tumours such as oral, breast and cervical cancer and other tumours such melanoma and colon cancer through photothermal ablation using gold-polymer nanoparticles and near infrared light. The researchers from Mumbai’s Indian Institute of Technology (IIT) Bombay and Tata Memorial Centre have synthesised hybrid polymer-gold nanoparticles as photothermal agent to ablate solid tumours. The near infrared light heats up the nanoparticles and the heated nanoparticles, in turn, can kill the cancer cells. Unlike other agents tried out by others, the hybrid nanoparticles used by the Mumbai team has no toxicity, is biodegradable and gets cleared from the body through urine. The team led by Prof. Rohit Srivastava from the Department of Biosciences and Bioengineering at IIT Bombay and Dr. Abhijit De from the Molecular Functional Imaging Lab at ACTREC, Tata Memorial Centre used a thermoresponsive polymer (poly(N-vinyl caprola...

Here is all you need to know about Google Tez, the latest entrant to the digital payment marketplace. Google made its foray into the burgeoning mobile payments sector in India on Monday by launching its mobile wallet app, Google Tez, at an event in New Delhi attended by Finance Minister Arun Jaitley. Here is all you need to know about the latest entrant to the digital payment marketplace. How does it work? Google Tez is a mobile wallet based on the Unified Payments Interface (UPI) platform built by the National Payments Corporation of India (NPCI). UPI-enabled wallets permit users to transfer money without requiring the bank account details of the recipient. The UPI ID of the recipient is used as a proxy for the account number and IFSC code, thereby simplifying the process of money transfer. How is it different from other digital wallets? Unlike most other wallets apps, it does not require money to be stored in the app to make digital payments. Tez works as an exte...

Hackers broke into British company Piriform's free software for optimizing computer performance last month and installed tools that could have allowed them to take control of tens of millions of devices, the company and independent researchers said on Monday. The malicious program was slipped into legitimate software called CCleaner, which is downloaded for personal computers and Android phones as often as 5 million times a week. It cleans up junk programmes and advertising cookies to speed up devices. CCleaner is the main product made by London's Piriform, which was bought in July by Prague-based Avast, one of the worlds largest computer security vendors. At the time of the acquisition, the company said 130 million people used CCleaner. A version of CCleaner downloaded in August included remote administration tools that tried to connect to several unregistered web pages, presumably to download additional unauthorized programs, security researchers at Cisco's Ta...

The birch bark scroll is known as the Bakhshali manuscript after the village, which is now in Pakistan, where it was found buried in 1881. A black dot on a third-century Indian manuscript has been identified by Oxford University as the first recorded use of the mathematical symbol for zero, 500 years earlier than previously thought. "Scientists from the University of Oxford's Bodleian Libraries, have used carbon dating to trace the figure's origins to the famous ancient Indian scroll," the university said in a statement. The birch bark scroll is known as the Bakhshali manuscript after the village, which is now in Pakistan, where it was found buried in 1881. It has been held at the Bodleian Libraries since 1902. "The creation of zero as a number in its own right, which evolved from the placeholder dot symbol found in the Bakhshali manuscript, was one of the greatest breakthroughs in the history of mathematics," said Marcus du Sautoy, a mathem...

Resilient ‘sheet’ being developed by Aerospace Corporation Scientists are developing an ultra-thin spacecraft that can remove space debris — which potentially threatens satellites or astronauts — by enveloping junk in the Earth’s orbit and dragging it through the atmosphere, causing it to burn up. The Brane Craft, being developed by U.S.-based Aerospace Corporation, is flexible and measures less than half the thickness of a human hair. “It has to be bullet-proof, because a five-micron diametre particle can penetrate the main structural sheet, which is only 10 microns thick,” said senior scientist Siegfried Janson . The spacecraft’s microprocessor and digital electronics are fabricated in such a way that if one component gets damaged, the others will continue to work.
