TRAI Gives a Boost to Net Neutrality

India’s telecom regulator has backed an open and free internet, saying internet service providers cannot discriminate on how people access web content. The Telecom Regulatory Authority of India (Trai) upheld the concept of so-called net neutrality and said no Internet Service Provider (ISP) can grant preferential data speeds or treatment to any web content.The global debate over net neutrality revolves around whether ISPs should be treated like public utilities to ensure the internet is open and free, or be allowed to prioritise access to content of their choosing for an extra fee from websites and services. India’s stand on net neutrality contrasts that of the US telecom.

Mitra- The Robot who Greeted Ivanka

Mitra, a humanoid robot developed by Bengaluru based Invento Robotics, greeted Ivanka Trump and PM Narendra Modi at the Hyderabad Convention Centre (HICC). The robot, named after the Vedic god of friendship, is a poster child for cooperation in artificial intelligence between India and China.

Mitra is designed to be an “indoor autonomous robot” or one that can be deployed in offices, hospitals and even multiplex cinemas. “The computer-aided designing has been done in India. Its plastic mould is being made in a factory in Dongguan and the printed circuit boards and motor controls are being manufactured in Shenzhen.

New Norms to Check Misuse of Stem Cells

In the backdrop of proliferation of indiscriminate use of stem cell-based therapies and misleading claims by private entities, the Central government has come up with a set of draft national guidelines for stem-cell research to curb malpractices in the field. The guidelines prepared jointly by ICMR and DBT seek to impose a ban on the commercial use of stem cells as part of the therapy

ISRO Plans a Rocket that can be Made in Three Days

In a development that will revolutionalise the satellite launch system in the country, Indian Space Research Organisation (Isro) is developing a small launch vehicle that can be assembled in just three days as compared to 30-40 days for a normal-sized PSLV and can be built at a cost which will be just one-tenth the original manufacturing cost of a PSLV. The manufacturing cost of a launch vehicle is generally in the range of Rs 150 crore to Rs 500 crore across the world. Isro has started working on the idea of building this small rocket keeping in mind the emerging market of nano satellites.Till now, satellites of foreign customers are accommodated in launch vehicles only as secondary passengers. With Isro eyeing to capture the market of nano satellites, the small vehicle can be a boon for foreign satellite customers as the rocket can be readied in just three days on demand.

IIT- Roorkee Develops High- Speed Memory Device

A team at IIT Roorkee has developed a memory device which can read and write memory at a high speed while consuming low energy. The development of such a chip suggests a new leap of technology as currently the key limitation of memory-related technology was the two-bit ability.The applications of this chip can be found across domains such as signal processing, artificial intelligence, machine learning, and virtual reality among others. It can impact the speed at which memory-intensive tasks such as video viewing or playing mobile games are undertaken.

Apart from the fact that the device consumes low energy, the key advantage of this device over existing technology is its non-volatility which means it is capable of retaining data even when power is off. Additionally, the chip utilizes voltage instead of large electric current to switch the magnetic bits and write data into the memory which not only makes the process faster but also reduces the cost per bit.
