Your monthly dose of the latest in science and technology

With the beginning of a new decade, we bring to you the latest breakthroughs in the field of internet connectivity, genetic engineering, defense tech and space exploration. With the ever-changing pace of discoveries and inventions, read on to know more about how these breakthroughs are going to take Human civilization forward!

5G — The new era of connectivity!

For nearly a decade, 5G has been in the making, and it is finally becoming a reality.

The fifth-generation wireless technology for digital cellular networks started rolling out in select cities a few years ago. You’ll be able to see the exponentially faster download and upload speeds with this new kind of network which uses cutting-edge network technology and the latest high-specced devices. It will also expand mobile networks to support a vast diversity of devices and services.

Unlike 4G LTE, 5G will be operating on three different spectrum bands. It adds huge amounts of spectrum in bands that haven’t been used for commercial broadband traffic. Carriers are running out of LTE capacity in many major cities where users are already experiencing slowdowns during busy times of the day.

5G can also help in the working of autonomous vehicles. Vehicles can communicate with other vehicles on the road, provide information to other cars about road conditions, and offer performance information to drivers and automakers. It will also help in domains such as public safety and infrastructure, remote device control and health care.

By 2035, 5G’s full economic effect will be realized across the globe and it can support a wide range of industries potentially producing up to $12 trillion worth of goods and services and support up to 22 million jobs, according to a landmark 5G Economy study.

5G network has already been launched in places like the US, UK and Australia. As for India, 5G is expected to become available for subscription in 2022, Swedish telecom gear maker Ericsson said in a report released on 25th November 2019.

New Tech Entering Defense

An impressive solution for alternate modes of aircraft propulsion has been proposed by a startup company known by the name Jetoptera. They have developed and patented new technology, a potential solution — Fluidic Propulsion.

Fluidic Propulsion is driven by pairing the simple architecture of a gas generator with an advanced augmentation system. The revolutionary technology gives significantly superior efficiency versus typical small turbojets. It also guarantees great ability to operate and low fuel burn at all stages of flight.

“Our low-risk solution is fuel-efficient, can utilize a variety of fuels such as JP-5, JP-8 or become fully electric, and is significantly quieter in forward flight operations,” said Todd Newton, Vice President of Business Development for Jetoptera.

Recently, aerospace giants like General Electric and Honeywell Aerospace have entered into joint ventures with Jetoptera to take this incredible technology into the defense sector and later, in the coming years, diving into less explored spaces like Air Taxis.

With 3 critical patents already in its name, Jetoptera’s pace seems to be very promising and with the backing of strong organizations like those above, they really seem to be taking off.

A new breakthrough in Genetic Engineering — Regeneration

The idea of growing back any lost limbs or organs, and regaining the feeling of wholesomeness has transcended all civilizations. It has been adapted into science fiction and even superhero comics as an invaluable mutation or superpower.

Unfortunately, this idea, like many others, remains a fantasy. Yet, researchers continue to pursue this medical miracle with the same zest as before. And now they have a breakthrough.

A group of researchers have studied a species of salamander, Axolotl, scientifically known as Ambystoma Mexicanum. It is a relative of the tiger Salamander and has regenerative powers that are unseen in more complex animal-systems.

Scientists are extremely excited about the possibility of isolating the regenerative genes that are present in the Axolotl’s genome. The heavy enthusiasm, however, is slightly dimmed by the size of the Axolotl’s genome that is 10 times the size of the human genome. A larger genome makes it difficult to accurately find the genes responsible for regeneration. However, the scientists are positive about the chances of identifying, isolating, extracting and implanting the genes. This could later prove highly effective and may evolve the human genome to include these genes. If not helping with the absorption of the gene, it could produce highly effective regenerative serums and drugs that may eliminate prosthetic and implants completely.

Never-seen-before image of the Sun!

The Daniel K. Inouye Solar Telescope in Hawaii has produced the highest resolution video of the Sun’s surface ever created, revealing what looks like exploding bits of caramelized popcorn covering the star at the heart of our Solar System.

The telescope, which is said to be the largest and most powerful solar telescope in the world, captured these images last month in its pursuit to probe the sun’s magnetic field. This was done for studying the activities that drive space weather in Earth’s neighborhood. It will also delve into one of the most counter intuitive solar mysteries: why the sun’s corona, or outer layer, is hotter than its visible surface.

To create the molten-looking video above, the telescope observed the Sun for a total of 10 minutes, focusing on a region just 18 miles across. The “popping” cells in the video are plasma rising up out of the Sun, cooling off, and then retreating back downward.
