Chilled panels use less energy than conventional A/C and work in open spaces.

Many people beat the summer heat by cranking the air conditioning. However, air conditioners guzzle power and spew out millions of tons of carbon dioxide daily. They’re also not always good for your health—constant exposure to central A/C can increase risks of recirculating germs and causing breathing problems.

There’s a better alternative, say a team of researchers from the University of British Columbia, Princeton University, the University of California, Berkeley and the Singapore-ETH Centre.

Min-Liang Tan, chief executive of gaming company Razer, said that the Covid-19 pandemic is driving the internet to the next stage of its evolution – something called the ‘Metaverse’ where cyberspace becomes more of an interactive 3D space with commerce and networking alongside content, much like the worlds in popular games such as Fortnite and Roblox.

The metaverse concept was brought to life by the 2018 sci-fi movie Ready Player One, directed by Steven Spielberg.

For a while, there has been speculation about to what degree Tesla was using GPS data versus actual detection of speed limit signs in order to detect speed limits for its Autopilot features.

Now this new udpate gives us some answers.

Today, Tesla started releasing its 2020.36 software update and it includes several new features including one called ‘Speed Assist Improvements’.

They’re in pigs already, and the company is planning for human testing.

Picture an airplane that can only climb to one or two altitudes after taking off. That limitation would be similar to the plight facing scientists who seek to avoid instabilities that restrict the path to clean, safe, and abundant fusion energy in doughnut-shaped tokamak facilities. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics (GA) have now published a breakthrough explanation of this tokamak restriction and how it may be overcome.

Toroidal, or doughnut-shaped, tokamaks are prone to intense bursts of heat and particles, called edge localized modes (ELMs). These ELMs can damage the reactor walls and must be controlled to develop reliable fusion power. Fortunately, scientists have learned to tame these ELMs by applying spiraling rippled magnetic fields to the surface of the plasma that fuels fusion reactions. However, the taming of ELMs requires very specific conditions that limit the operational flexibility of tokamak reactors.

The bug, now fixed, could be abused to steal sensitive and private data from other apps.

If a tree falls in a forest and no one is there to hear it, does it make a sound? Perhaps not, some say.

And if someone is there to hear it? If you think that means it obviously did make a sound, you might need to revise that opinion.

We have found a new paradox in quantum mechanics – one of our two most fundamental scientific theories, together with Einstein’s theory of relativity – that throws doubt on some common-sense ideas about physical reality.

Amazon’s Prime Air drone delivery plans scored a boost on Thursday. The Federal Aviation Administration approved an exemption allowing the company to move forward with operations while working towards formal certification of the MK27 UA aircraft and the airline operations. The approval comes with significant limits, but allows the company to continue development of the platform and supports progress towards the necessary certifications.

The relief provided in this 44807 exemption would enable the Amazon MK27 unmanned aircraft (MK27 UA) and associated aircraft systems (MK27 UAS) to operate in cargo delivery operations without an airworthiness certificate. The FAA concludes that Amazon’s compliance with the conditions and limitations of this exemption, along with the FAA’s safety evaluation of the MK27 UAS, will enable Amazon’s operations using the MK27 UAS without adversely affecting safety. Amazon is currently engaged in the process to receive a type certificate for the MK27 UAS utilized in its operations.

The embryos, which were not allowed to develop past 28 days of age, move researchers a small step closer to perhaps growing human organs for medical transplant.

Every hour, six people in the United States are added to the national waiting list for organ transplants—and each day, 22 people on the list die waiting. In the U.S. alone, more than a hundred thousand people need heart transplants each year, but only about 2,000 receive one.

In response, researchers are working to artificially expand the organ supply. Some are trying to 3D print organs in the lab. Others are working on artificial, mechanical organs. And some are making chimeras—hybrids of two different species—in the hopes of growing human organs in pigs or sheep.
