Looking Back At 2020 — Tesla/SpaceX/Starlink/5G/mRNA + more
Are you fed up with all the negativity?
Between Tesla, SpaceX (Starship & Starlink), 5G, mRNA vaccines and more, 2020 has been an eventful year full of breakthroughs all set to make our lives better, and ushering in a sci-fi future quicker than ever…so I brought them all together in one video to celebrate the great people working tirelessly to make our future better.
If you want a feel good boost, why not drop by and spend a few mins revelling in the positive stories of 2020.
Have an awesome New Year!!
In Looking Back At 2020 I want to review the year to show that for all the bad, there was still some amazing good and positive stories that refused to take a back seat.
Researchers achieve sustained, high-fidelity quantum teleportation
A viable quantum internet—a network in which information stored in qubits is shared over long distances through entanglement—would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication.
This month, scientists at Fermi National Accelerator Laboratory—a U.S. Department of Energy national laboratory affiliated with the University of Chicago—along with partners at five institutions took a significant step in the direction of realizing a quantum internet.
In a paper published in PRX Quantum, the team presents for the first time a demonstration of a sustained, long-distance teleportation of qubits made of photons (particles of light) with fidelity greater than 90%.
The Rand Corp Has Just Published a Paper on Internet-Connected “Smart” Devices Which Track Body Functions
For those of us who don’t think that even our bowel movements will soon be inventoried, tracked and timestamped during every moment of existence, here is a just published white paper from the Rand Corporation, an influential think tank created in 1948 to offer research and analysis to the US military, which begs to differ.
The November 2020 whilte paper, published under the title “The Internet of Bodies,” focuses on the advantages and disadvantages, security and privacy risks, plus the ethical implications of what it calls a growing “Internet of Bodies (IoB).”
IoB tools are internet-connected “smart” devices increasingly available in the marketplace which promise to track and upload to the internet measurements related to individual heartbeat, blood pressure and other bodily functions in real time for purposes of health, exercise, security or other reasons.
Wait, What? New Research Says Internet Use Is Killing Your Memory
This doesn’t sound good. 😃
The scientists put hundreds of participants through memory and cognitive tasks as well as brain scans, according to the research, published last month in the journal World Psychiatry.
Joseph Firth, the Western Sydney University scientist who led the project, described in a press release how the internet’s design is changing both the structure and abilities of the human brain.
The “limitless stream of prompts and notifications from the Internet encourages us towards constantly holding a divided attention,” said Firth, “which then in turn may decrease our capacity for maintaining concentration on a single task.”
Exploring the potential of near-sensor and in-sensor computing systems
As the number of devices connected to the internet continues to increase, so does the amount of redundant data transfer between different sensory terminals and computing units. Computing approaches that intervene in the vicinity of or inside sensory networks could help to process this growing amount of data more efficiently, decreasing power consumption and potentially reducing the transfer of redundant data between sensing and processing units.
Researchers at Hong Kong Polytechnic University have recently carried out a study outlining the concept of near-sensor and in-sensor computing. These are two computing approaches that enable the partial transfer of computation tasks to sensory terminals, which could reduce power consumption and increase the performance of algorithms.
“The number of sensory nodes on the Internet of Things continues to increase rapidly,” Yang Chai, one of the researchers who carried out the study, told TechXplore. “By 2032, the number of sensors will be up to 45 trillion, and the generated information from sensory nodes is equivalent to 1020 bit/second. It is thus becoming necessary to shift part of the computation tasks from cloud computing centers to edge devices in order to reduce energy consumption and time delay, saving communication bandwidth and enhancing data security and privacy.”
AT&T outage: Internet, 911 disrupted, planes grounded after Nashville explosion. Get the latest updates
“Power is essential to restoring wireless and wireline communications, and we are working with law enforcement to get access to our equipment and make needed repair,” the statement said. “There are serious logistical challenges to working in a disaster area and we will make measurable progress in the hours and days ahead.
We’re grateful for the work of law enforcement as they investigate this event while enabling us to restore service for our customers.
The outages were reported several hours after an explosion in downtown Nashville that took place near an AT&T facility.
Scientists Invent a Flexible Device That Converts Wi-Fi Signals Into Electricity
We can probably all agree that charging cables are just the worst, and that we’d love to have fewer of them in our lives. Now, a new invention might give us just that: engineers have developed a flexible device that harvests energy from Wi-Fi signals.
And not just harvest. It can then convert it into electricity that could be used to power devices, wire-and battery-free.
The device is what is known as a rectenna — a portmanteau of ‘rectifying antenna’ — which is a type of antenna that converts electromagnetic energy into direct current (DC).
Soon We Can All Join Paul Rudd in Mastering Quantum Chess
Last week the Internet learned that “Anyone Can Quantum,” when actor Paul Rudd faced off against Stephen Hawking in a game of quantum chess. The 12-minute video has racked up more than 1.5 million views, with Fast Company declaring it one of the best ads of the week. And soon we’ll all be mastering the rules of the subatomic realm, with today’s launch of a Kickstarter campaign to create a commercial version of quantum chess.
Beam me up: long-distance quantum teleportation has happened for the first time ever
Raise your hand if you ever wanted to get beamed onto the transport deck of the USS Enterprise. Maybe we haven’t reached the point of teleporting entire human beings yet (sorry Scotty), but what we have achieved is a huge breakthrough towards quantum internet.
Led by Caltech, a collaborative team from Fermilab, NASA’s Jet Propulsion Lab, Harvard University, the University of Calgary and AT&T have now successfully teleported qubits (basic units of quantum info) across almost 14 miles of fiber optic cables with 90 percent precision. This is because of quantum entanglement, the phenomenon in which quantum particles which are mysteriously “entangled” behave exactly the same even when far away from each other.
