The wellness case for learning new skills

In the summer of 2016 I was very unhappy. I was coming up on my year anniversary of living in London, where we had moved from Brooklyn for my husband’s job, but I still felt pitifully lonely and poorly adjusted to the culture. I reentered therapy, tried to socialize often, started volunteering, and focused on doing things for pleasure rather than out of obligation.

But there was one thing that alleviated my sadness more than others: I learned to drive a stick shift.

In Europe, automatics were more expensive to rent, so it was in my best interest to try to overcome any manual driving anxiety head-on. My husband and I decided to spend two weeks in France, and I spent much of that vacation stalling out on country roads, navigating dreaded traffic circles, and ultimately speeding down the highways. When I returned to London I told people about the beaches and baguettes in France, but I mostly wanted to talk about how I could now officially drive stick.

I had discovered the beauty of “micromastery”: working to develop competence in a single, concrete skill. The term was coined by the writers Tahir Shah and Robert Twigger; Twigger later published his 2017 book, Micromastery: Learn Small, Learn Fast, and Unlock Your Potential to Achieve Anything, which contains instructions for laying a brick wall, making sushi, and brewing beer. In the introduction, Twigger writes that he was stymied by the idea that he had to work for years to acquire any truly valuable skill, but that he still wanted to learn and create, so he decided to focus on making the perfect omelet: his first micromastery.

An ‘EpiPen’ for spinal cord injuries

F32FA809-CCC1-4FF0-B49E-4486BDB2FC6F

ANN ARBOR—An injection of nanoparticles can prevent the body’s immune system from overreacting to trauma, potentially preventing some spinal cord injuries from resulting in paralysis.

The approach was demonstrated in mice at the University of Michigan, with the nanoparticles enhancing healing by reprogramming the aggressive immune cells—call it an “EpiPen” for trauma to the central nervous system, which includes the brain and spinal cord.

“In this work, we demonstrate that instead of overcoming an immune response, we can co-opt the immune response to work for us to promote the therapeutic response,” said Lonnie Shea, the Steven A. Goldstein Collegiate Professor of Biomedical Engineering.

Simple ‘smart’ glass reveals the future of artificial vision

D650F108-27FF-47E2-9A5D-721216EA59B6

From left to right, Zongfu Yu, Ang Chen and Efram Khoram developed the concept for a “smart” piece of glass that recognizes images without any external power or circuits.

The sophisticated technology that powers face recognition in many modern smartphones someday could receive a high-tech upgrade that sounds — and looks — surprisingly low-tech.

This window to the future is none other than a piece of glass. University of Wisconsin–Madison engineers have devised a method to create pieces of “smart” glass that can recognize images without requiring any sensors or circuits or power sources.

Physicists use light waves to accelerate supercurrents, enable ultrafast quantum computing

17648120-9B52-42E8-B1CC-EBE587765DF5

Scientists have discovered that terahertz light — light at trillions of cycles per second — can act as a control knob to accelerate supercurrents. That can help open up the quantum world of matter and energy at atomic and subatomic scales to practical applications such as ultrafast computing.

Jigang Wang patiently explained his latest discovery in quantum control that could lead to superfast computing based on quantum mechanics: He mentioned light-induced superconductivity without energy gap. He brought up forbidden supercurrent quantum beats. And he mentioned terahertz-speed symmetry breaking.

Then he backed up and clarified all that. After all, the quantum world of matter and energy at terahertz and nanometer scales — trillions of cycles per second and billionths of meters — is still a mystery to most of us.

Baldness breakthrough uses 3D-printed “hair farms” to grow new hair follicles

520E2D84-D515-4C9F-B665-496448B22190

The 3D-printed structure can for the first time grow human hair follicles entirely in a laboratory dish

An exciting breakthrough from Columbia University researchers demonstrates a new way to grow human hair follicles using 3D printed molds. This is the first time human hair follicle cells have been grown completely in lab conditions, opening up a potentially unlimited source of hair follicles for future hair restoration surgical procedures.

Over the last few decades hair transplantation surgery has rapidly evolved, becoming more sophisticated and successful, however the process has still fundamentally relied on hair follicles being redistributed from one part of the body to another. Growing human hair follicles in laboratory conditions has proved challenging for researchers, ultimately limiting the efficacy of hair restoration surgery, especially in patients without hair already present that can be grafted.

This new breakthrough brings together a couple of recent innovations. First, the researchers created a unique plastic mold using 3D printers. The moulds are designed to resemble a natural micro-environment stimulating hair follicle growth through tiny extensions just half a millimeter wide.

Construction companies are developing an AI system that predicts worksite injuries—an example of the growing use of workplace surveillance.

A construction site is a dangerous place to work, with a fatal accident rate five times higher than that of any other industry.

Now a number of big construction companies are testing technology that could save lives, and money, by predicting when accidents will happen.

This cool artificial reef was just deployed in Sydney Harbor

Earth’s oceans have seen better days. They’re inundated with plastic waste, both whole single-use plastics and tons of plastic microparticles that find their way back into our food and drinking water. Their water temperatures are rising due to climate change, causing coral bleaching and other harmful phenomena. Overfishing has depleted multiple marine species.

Organizations and individuals around the world have leaped to action to try to reverse some of the damage human activity has caused the oceans. The Ocean Cleanup is using a two-kilometer-long screen to collect plastic waste. Origin Materials aims to make a new type of plastic that’s sustainable and renewable. The 5 Gyres Institute’s mission is to end plastic pollution, which it calls a global health crisis

Last week another effort joined the ranks: a purpose-built artificial reef in Sydney Harbor. The result of a three-year partnership between the University of Technology Sydney (UTS), the Sydney Opera House, and the government of New South Wales, the reef was made by Reef Design Lab and consists of eight one-meter-tall pods, each containing three steel and concrete hexagonal structures. Half the units also have triangular tiles extending from the hexagons’ cores.

The road of the future is likely to become the brain and nerve center of an autonomous-driving revolution.

The road to China’s autonomous-driving future is paved with solar panels, mapping sensors and electric-battery rechargers as the nation tests an “intelligent highway” that could speed the transformation of the global transportation industry.

The technologies will be embedded underneath transparent concrete used to build a 1,080-meter-long (3,540-foot-long) stretch of road in the eastern city of Jinan. About 45,000 vehicles barrel over the section every day, and the solar panels inside generate enough electricity to power highway lights and 800 homes, according to builder Qilu Transportation Development Group Co.

This week, Denver, CO became the first city in the United States to decriminalize psilocybin, a compound with hallucinogenic properties that occurs in some mushrooms — a move that could signal new frontiers both in the country’s evolving relationship with mind-altering substances and in the medical community’s accelerating exploration of psychedelics.

“Because psilocybin has such tremendous medical potential, there’s no reason individuals should be criminalized for using something that grows naturally,” said Kevin Matthews, the director of the campaign to legalize psilocybin in Denver, in an interview with the New York Times.

The new law passed by a narrow margin, according to the Times, of less than 2,000 votes. It doesn’t entirely legalize psilocybin-containing mushrooms, but it makes the prosecution of possession and cultivation of them an extremely low-priority offense.

While the world watched in shock as part of Notre Dame cathedral burned, few realized the surprising roles machines played in the incident. Sadly, a possible computer glitch may have been responsible for the fire. But technology was also crucial to the recovery efforts. French firefighters used DJI drones to survey the blaze and assess their attack plan — something a Paris Fire Brigade spokesperson said was important in saving the historic building. And a water cannon-manned robot named Colossus also helped battle the raging fire.

When talking about dream future drone applications at a Techcrunch AI and robotics event held at UC Berkeley on Thursday, DJI head of U.S. research and development Arnaud Thiercelin shared his obsession with the idea of fighting fires with drones in what he refers to as an “aerial aqueduct.”
