Rooftop solar, Covid and more large scale renewables push Australia’s main grid to record low levels of demand and emissions intensity, and the lowest prices in years.

The combined impact of growing rooftop solar and the Covid-19 pandemic – along with the continued influx of large scale wind and solar – has create a suite of new records in Australia’s electricity grids in the September quarter, sending demand, emissions and prices to new lows.

The latest Quarterly Energy Dynamics for the September quarter, compiled by the Australian Energy Market Operator, also noted record highs for wind and solar output, which along with falling gas prices and cut-price bidding by coal generators trying to stay competitive led to the lowest wholesale prices in more than five years, and in some cases, record low prices.

MIT researchers reinvented the wheel, turning any basic bike into a hybrid booster.

So now, there are AI doctors.

Machine learning is taking medical diagnosis by storm. From eye disease, breast and other cancers, to more amorphous neurological disorders, AI is routinely matching physician performance, if not beating them outright.

Yet how much can we take those results at face value? When it comes to life and death decisions, when can we put our full trust in enigmatic algorithms—“black boxes” that even their creators cannot fully explain or understand? The problem gets more complex as medical AI crosses multiple disciplines and developers, including both academic and industry powerhouses such as Google, Amazon, or Apple, with disparate incentives.

Chinese spies are different from those of most other wealthy and developed countries where the majority of spies are highly trained, with some serving under diplomatic cover and others operating under what the US Intelligence Community calls Non Official Cover (NOC).

Chinese intelligence operations are the first in modern times to use, as a foundation, the whole of society. Because of this, China’s espionage tactics are sometimes artless, operating with little in the way of standard spy-fare, (encrypted communication, dead drops, etc.) instead relying on an overwhelming volume of espionage operations conducted by all manner of citizen and a sort of impunity inherent in the lack of substantive penalty for when a Chinese agent is discovered, a study I recently published analyzing 595 cases of intelligence collection efforts sanctioned and abetted by the Chinese Communist Party.

“The mobile gravity suit is a small, untethered, and flexible intravehicular activity (IVA) suit,” the researchers wrote in their paper published in the Frontiers in Physiology journal.

The idea is to give astronauts maximum flexibility while on board a spacecraft, without reducing crew time. “With the gravity suit, astronauts will be able to float freely around the space station while adhering to their every day tasks,” the paper reads.

“The negative pressure is generated by its own portable vacuum system, ensuring full mobility, and user-control,” the paper reads.

IBM’s concept of quantum volume tries to measure quantum computing progress in ways beyond counting qubits.
