Some interesting new information on how humans use energy and why exercise is not necessarily useful for losing weight (though it can help prevent gaining weight in the first place and of course is good for health).

I’m still curious why I accidentally lost about 30 pounds without intending to while I was eating probably twice as much as normal when I spent three months at the South Pole (2007−08). Did the cold increase my brown fat and my metabolism? Did it have something to do with unpolluted air and water? Was it a difference in the food, most of which was from New Zealand? Was it the high altitude (equivalent to about 10,500 feet at the equator)? Did the roughly 30 pounds of extra clothing I wore every day somehow trigger weight loss to “maintain” my previous weight? Something else?

As this example shows, there is still a great deal we can learn about these questions which are crucial to maintaining human health.

The robot takeover starts at the drive thru as fast food rapidly turns to automation.

Historically, the first program you write for a new computer language is “Hello World,” or, if you are in Texas, “Howdy World.” But with quantum computing on the horizon, you need something better. Like “Hello Many Worlds.” [IonQ] proposes what that looks like and then writes it in seven different quantum languages in a post you should check out.

Here’s the description of the simple program:

The basic quantum program we’ll write is simple. It creates a fully-entangled state between two qubits, and then measures this state. This state is sometimes called a Bell State, or Bell Pair, after physicist John Stewart Bell.

The omicron wave that assaulted the United States this winter also bolstered its defenses, leaving enough protection against the coronavirus that future spikes will likely require much less — if any — dramatic disruption to society.

Millions of individual Americans’ immune systems now recognize the virus and are primed to fight it off if they encounter omicron, or even another variant.

About half of eligible Americans have received booster shots, there have been nearly 80 million confirmed infections overall and many more infections have never been reported. One influential model uses those factors and others to estimate that 73% of Americans are, for now, immune to omicron, the dominant variant, and that could rise to 80% by mid-March.

Within the human brain, neurons perform complex calculations on information they receive. Researchers at MIT have now demonstrated how dendrites—branch-like extensions that protrude from neurons—help to perform those computations.

The researchers found that within a single neuron, different types of dendrites receive input from distinct parts of the brain, and process it in different ways. These differences may help neurons to integrate a variety of inputs and generate an appropriate response, the researchers say.

In the neurons that the researchers examined in this study, it appears that this dendritic processing helps cells to take in visual information and combine it with motor feedback, in a circuit that is involved in navigation and planning movement.

In a paper published by Science, DeepMind demonstrates how neural networks can improve approximation of the Density Functional (a method used to describe electron interactions in chemical systems). This illustrates deep learning’s promise in accurately simulating matter at the quantum mechanical.

In a paper published in the scientific journal Science, DeepMind demonstrates how neural networks can be used to describe electron interactions in chemical systems more accurately than existing methods.

Density Functional Theory, established in the 1960s, describes the mapping between electron density and interaction energy. For more than 50 years, the exact nature of mapping between electron density and interaction energy — the so-called density functional — has remained unknown. In a significant advancement for the field, DeepMind has shown that neural networks can be used to build a more accurate map of the density and interaction between electrons than was previously attainable.

While it’s difficult to put something as vast, conceptual, and, frankly still emerging as the metaverse in quantifiable terms, Jon Radoff breaks it down logically and thoroughly.

When it comes to describing the metaverse, definitions and opinions abound. And while it’s difficult to put something as vast, conceptual, and, frankly, still emerging as the metaverse into quantifiable terms, Jon Radoff, entrepreneur, author and game designer, breaks it down logically and thoroughly in Measuring the Metaverse. He moves up the value chain from infrastructure at the bottom to experience at the top, stopping at human interface, decentralization, spatial computing, creator economy, and discovery along the way.

A common framework is necessary in Radoff’s view of the metaverse. He writes, “And while there will be many proprietary (and very fun) theme parks in the metaverse, I’m even more excited by the opportunity in the Switzerlands: a metaverse powered by a robust creator-economy enabled through decentralization.”

Before the pandemic started (ah, those glorious days…) a collective panic was mounting over automation and robots gradually replacing workers in various fields, or “stealing our jobs,” as the common refrain went. These worries haven’t subsided two years later, but they’re being countered by severe and largely unexpected labor shortages across multiple sectors of the economy. One of the industries that’s struggling most is restaurants. While we may still encounter automation-related unemployment problems down the road, right now it seems robots are lending a much-needed hand in food service.

One of these robots is none other than Flippy, initially debuted in 2017 to flip burgers at a California fast food chain. Since then Miso Robotics, Flippy’s maker, has expanded the bot’s capabilities, creating a version that can cook chicken wings, fries, and other greasy delights. This week also brought a significant expansion to Flippy’s presence as White Castle announced plans to install the robot at more than 100 restaurants this year.
