Nelson Dellis is a four-time USA Memory Champion and Grandmaster of Memory. Some of his feats of recollection include memorizing 10,000 digits of pi, the order of more than nine shuffled decks of cards, and lists of hundreds of names after only hearing them once.

But with a little dedication, Dellis says that anyone can improve their memory. Here are five steps to follow that will get your filling your head with information.

1. Start With Strong Images

Team with NASA to send off the Perseverance rover to Mars — from the convenience of your own home. The mission launches from Cape Canaveral, Florida, this summer, and you’re invited to participate remotely — with a global, collective launch countdown where you can submit your own videos, take a photo on Mars or next to the rover, dive into an interactive launch packet, and sign up to send your name to Mars on a future space mission.

After a seven-month journey to the Red Planet, the rover will land in Jezero Crater, an ancient lakebed with intriguing geology. In its search for astrobiological evidence of ancient microbial life, Perseverance will gather rock and soil samples there for future return to Earth. It will also characterize the planet’s climate and geology and pave the way for human exploration of the Red Planet.

In addition, Perseverance carries the Ingenuity Mars Helicopter, a technology demonstration that marks the first attempt at powered, controlled flight on another planet.

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the MAGIC scientists could now confirm that the speed of light is constant in vacuum — and not dependent on energy. So, like many other tests, GRB data also corroborate Einstein’s theory of General Relativity. The study has now been published in Physical Review Letters.

Einstein’s general relativity (GR) is a beautiful theory that explains how mass and energy interact with space-time, creating a phenomenon commonly known as gravity. GR has been tested and retested in various physical situations and over many different scales, and, postulating that the speed of light is constant, it always turned out to outstandingly predict the experimental results. Nevertheless, physicists suspect that GR is not the most fundamental theory, and that there might exist an underlying quantum mechanical description of gravity, referred to as quantum gravity (QG).

Some QG theories consider that the speed of light might be energy dependent. This hypothetical phenomenon is called Lorentz invariance violation (LIV). Its effects are thought to be too tiny to be measured, unless they are accumulated over a very long time. So how to achieve that? One solution is using signals from astronomical sources of gamma rays. Gamma-ray bursts (GRBs) are powerful and far away cosmic explosions, which emit highly variable, extremely energetic signals. They are thus excellent laboratories for experimental tests of QG. The higher energy photons are expected to be more influenced by the QG effects, and there should be plenty of those; these travel billions of years before reaching Earth, which enhances the effect.

The current market is expected to balloon to $1.0-$1.5 trillion in the next 20 years. Not even the anti-aging industry is worth that much!


The next decade is going to be an important one, with declining costs & advanced technology propelling the space economy to new highs. We have never been closer to the final frontier.

We need one in Nigeria too.


Elon Musk has come to hint about his wish to set up Tesla’s second gigafactory in Asia. As he responded to queries on the Twitter handle, he indicated that the location of the second outlet won’t be necessarily inside China.

The soaring market

At present, the third gigafactory in China happens to be the electric carmaker’s only operational facility across the globe, producing Tesla Model 3 sedans and stands on a 9,300,000-square feet ground. On the other hand, the company aims to expand its lineup in the country with a locally built Model 3 sedan which is expected to offer a longer driving range. The next goal under the plan lies in producing a brand new Model Y.

Imagine a manufacturing plant in which all the production equipment is continually changing in response to market needs. Robots churning out widgets, for instance, would reconfigure themselves based on data coming in from all points of the widget supply chain, as well as sensors monitoring the factory itself. The result is a smart factory that’s more agile and autonomous than previous generations of automation.

Also known as Industry 4.0, the smart factory runs on data and artificial intelligence, but connectivity forms the backbone of operations. The new fifth generation of mobile networks (5G) is a catalyst for this new industrial revolution because it offers much greater speed and bandwidth than previous networks, as well as low latency, or time required for data to travel between two points. 5G will work with and in some cases replace existing fixed, wired connections, making manufacturing more flexible and ready to implement innovations.

5G could replace wired Ethernet as well as Wi-Fi and 4G LTE networks that connect devices in factories, but one 5G supplier is starting with the basics: powering mobile devices and robots. At a new factory in Lewisville, Texas, Swedish telecom Ericsson has been turning out 5G infrastructure equipment with the aid of a 5G network in the plant itself. Ericsson, which is supplying 5G equipment to telecoms in the U.S. such as AT&T, Verizon, Sprint and T-Mobile, has forecast 190 million 5G subscribers by the end of 2020 and 2.8 billion by the end of 2025.

In mammals, such as humans, DNA contains genetic instructions that are transcribed—or copied—into RNA. While DNA remains in the cell’s nucleus, RNA carries the copies of genetic information to the rest of the cell by way of various combinations of amino acids, which it delivers to ribosomes. The ribosomes link the amino acids together to form proteins that then carry out functions within the human body.

The viral RNA is sneaky: its features cause the protein synthesis machinery of our cells to mistake it for RNA produced by our own DNA.

COVID-19 enters the body through the nose, mouth, or eyes and attaches to our cells. Once the virus is inside our cells, it releases its RNA. Our hijacked cells serve as virus factories, reading the virus’s RNA and making long viral proteins to compromise the immune system. The virus assembles new copies of itself and spreads to more parts of the body and—by way of saliva, sweat, and other bodily fluids—to other humans.


RNA research at the University of Rochester provides a foundation for developing antiviral drugs, vaccines, and other therapeutics to disrupt coronavirus.
