LiFi Internet might just be 100 times faster than WiFi, says report

The pilot testing of LiFi, an alternative technology to WiFi, has proved that it can send data at up to 1GBps, according to a report in The Telegraph UK. This is almost 100 times faster than the present WiFi technology. So what exactly is LiFi? It uses light to beam information via air. The technology was first discovered by Professor Harald ...

NASA to launch two sounding rockets to study Earth’s magnetic field

NASA is launching two sounding rockets over Norway to study how particles move in a region near the North Pole where the Earth’s magnetic field is directly connected to the solar wind. After the launch window opens on November 27, the CAPER and RENU 2 rockets will have to wait for low winds and a daytime aurora before they can ... Read More »

New touchscreen material to end daily smartphone charging

British scientists have invented a new type of touchscreen material that requires very little power to illuminate, with vivid colours and high visibility in direct sunlight. The team is already in talks with some big players in consumer electronics to see if their new material can replace current LCD touchscreens over the next few years. Developed by Bodie Technologies, a ... Read More »

Scientists discover transparent, high-performance LED displays

The finding opens the door to the practical application of monolayer materials, such as MoS2, in devices like LEDs and high-performance transistors. “One could develop high-performance LED displays that are transparent when powered off and flexible using the ‘perfect’ optoelectronic monolayers produced in this study,” the researchers said. Monolayer semiconductors have generated a great deal of buzz as they hold ... Read More »

Safety in numbers: Cracking the coefficient code

Decimal expansion of numbers was a common exercise in middle-school mathematics. Fractions like 1/5 and 1/4 were less taxing. Their decimal expansions terminated promptly at 0.2 and 0.25 respectively. But the fraction 1/3 was a little intriguing. Its decimal expansion did not terminate, but it soon became clear that a single digit, namely 3, started to repeat itself. For certain ... Read More »

New camera can measure greenhouse gases

Researchers have developed a new camera that can photograph and film methane in the air. It can be an important part of the efforts to measure and monitor greenhouse gases, according to researchers from Linkoping University and Stockholm University in Sweden. “The camera is very sensitive, which means that the methane is both visible and measurable close to ground level, ...

These are the best photos of Pluto you may see in decades: NASA

NASA’s New Horizons spacecraft has sent back the sharpest images of Pluto yet. According to NASA, these are the best close-up photos of Pluto that people may see for decades to come. The New Horizons spacecraft, no bigger than a piano, transmits data stored on its digital recorder each week from its flight through the Pluto System. These latest pictures ... Read More »

Researchers create new phase of Carbon, which is harder than diamonds

Q-carbon a new phase of solid carbon, created by researchers at the North Carolina State University, is harder than diamonds. Until now, diamonds have been considered the hardest naturally occurring material, but the discovery of the Q-Carbon heralds several new possibilities. “We’ve now created a third solid phase of carbon,” says Jay Narayan, the John C. Fan Distinguished Chair Professor of ... Read More »

NASA: Supply shipment takes off for International Space Station

A US shipment of much-needed groceries and other astronaut supplies rocketed toward the International Space Station for the first time in months Sunday, reigniting NASA’s commercial delivery service. If the Orbital ATK capsule arrives at the space station Wednesday as planned, it will represent the first US delivery since spring. “Santa is on his way!” Tory Bruno, president of rocket ...

Nano talk: liquid fuel gets an efficiency shot

Most of the engines today use liquid fuel to produce energy. Internal combustion engines in automobile industry, aero propulsion engines, and those used in the power generation industry, all of them use some sort of liquid fuel. The efficiency of liquid fuels cannot be increased by using the existing technologies. But given the ever-increasing demand for energy in the developing ... Read More »
