Quantum actions have quantum consequences. In the context of measurements, this often means that the very act of measuring a quantum system disturbs it.

Edmonton researcher to lead study on CBD's role in athletic performance

A new research initiative led by Edmonton-based Aurora Cannabis will look at whether hemp-derived cannabidiol (CBD) products could help athletes with their performance and recovery.

"We're looking for hard and true evidence that this is going to be beneficial or not," said Jason Dyck, an independent director on the board of Aurora Cannabis.

Aurora Cannabis and the Ultimate Fighting Championship (UFC), the biggest mixed martial arts organization in the world, have partnered to do the research.

Dyck is also a professor in the department of pediatrics at the University of Alberta and a Canada Research Chair in molecular medicine.

"This is an Aurora led partnership," Dyck said. "It is not related to my affiliation with the University of Alberta. In my role as an independent director, I will provide general oversight to the research that's planned with the UFC."

Dyck said he has been told that many UFC athletes are already using CBD products, either orally or topically.

"[The UFC] felt they needed a strong research component to validate the efficacy of that," he said. "They wanted us to partner with them and investigate how hemp derived CBD helps athletes in a variety of areas."

Dyck and his team will first look at how CBD can reduce inflammation to improve performance and training for athletes.

Other clinical studies will include pain management, injury and exercise recovery and mental health.

Researchers will also look for any adverse effects of CBD use.

New computer model explains faltering jet stream

Scientists in Germany have applied machine learning to model the weakening of the jet stream that is partly responsible for extreme weather events, including the long cold winter of 2019 that held much of North America and Europe in an icy grip.

It's a strange irony that the warming of the Arctic has been bringing colder winters to regions farther south. This is partly due to a change in the jet stream, a river of air flowing at hundreds of km/h high up in the stratosphere that runs all the way around the northern hemisphere. It marks the boundary between the mass of cold Arctic air that caps the top of our planet and the warmer air around the middle.
Battleground between hot and cold air

The jet stream is the battleground between these two air masses as the warm air tries to move north and the colder pushes south. This boundary line is constantly moving, and like all rivers, the jet stream meanders, sometimes wandering south, allowing the cold air to drop down to the mid-latitudes, which happened last winter, or it can curve northwards, bringing warm air up from the tropics, producing hot, dry periods.

The jet stream can also do the opposite, depending on when the meandering happens. If it flows north in January, we get a warmer winter. And if it dips south in July, we have a cool, wet summer.

Storm systems also tend to follow the jet stream, so it has a strong effect on the weather patterns for the entire continent.

Any body on here have any recommendations on a microscope for a 9 year old book worm / wiz kid / budding scientist?

That comes with all the slides etc, should probably go that route. Was looking at a used one in local classifieds but wouldn't come with any of that.

Physicists can predict the jumps of Schrodinger's cat (and finally save it)



ale researchers have figured out how to catch and save Schrödinger's famous cat, the symbol of quantum superposition and unpredictability, by anticipating its jumps and acting in real time to save it from proverbial doom. In the process, they overturn years of cornerstone dogma in quantum physics.

The discovery enables researchers to set up an early warning system for imminent jumps of artificial atoms containing quantum information. A study announcing the discovery appears in the June 3 online edition of the journal Nature.

Schrödinger's cat is a well-known paradox used to illustrate the concept of superposition—the ability for two opposite states to exist simultaneously—and unpredictability in quantum physics. The idea is that a cat is placed in a sealed box with a radioactive source and a poison that will be triggered if an atom of the radioactive substance decays. The superposition theory of quantum physics suggests that until someone opens the box, the cat is both alive and dead, a superposition of states. Opening the box to observe the cat causes it to abruptly change its quantum state randomly, forcing it to be either dead or alive.

The quantum jump is the discrete (non-continuous) and random change in the state when it is observed.

The experiment, performed in the lab of Yale professor Michel Devoret and proposed by lead author Zlatko Minev, peers into the actual workings of a quantum jump for the first time. The results reveal a surprising finding that contradicts Danish physicist Niels Bohr's established view—the jumps are neither abrupt nor as random as previously thought.

For a tiny object such as an electron, molecule, or an artificial atom containing quantum information (known as a qubit), a quantum jump is the sudden transition from one of its discrete energy states to another. In developing quantum computers, researchers crucially must deal with the jumps of the qubits, which are the manifestations of errors in calculations.

The enigmatic quantum jumps were theorized by Bohr a century ago, but not observed until the 1980s, in atoms.

"These jumps occur every time we measure a qubit," said Devoret, the F.W. Beinecke Professor of Applied Physics and Physics at Yale and member of the Yale Quantum Institute. "Quantum jumps are known to be unpredictable in the long run."

"Despite that," added Minev, "We wanted to know if it would be possible to get an advance warning signal that a jump is about to occur imminently."
