Elon Musk’s SpaceX plans to send civilians into low-Earth orbit this year. Virgin Galactic is training space travellers. Companies aim to open hotels in space, and offer space day trips, within a few years. We assess the state of play in the nascent space tourism industry.

Massive solar storms in space can be picked up by iOS and Android smartphones, meaning billions of people have a personal geomagnetic storm detector — but the signals threaten to interfere with future location-based applications.

Hoping to get the public more involved in science, study author Sten F. Odenwald, an astronomer at the NASA Goddard Spaceflight Center, published a paper on the topic April 2 in Space Weather. It indicates that even through the unavoidable interference caused by other smartphone components, the phone’s built-in magnetometers can detect geomagnetic storms.

“Smartphones — at least theoretically — should be able to detect some of the strongest storms, pretty easily in fact,” Odenwald told The Academic Times. “Especially if you happen to live up in the northern latitudes — in Minnesota or in Canada, or places like that where it really rocks and rolls.”

A global shortage of semiconductors — chips that power massive data-centers, modern autos and countless digital devices — has roiled global manufacturing and is not expected to end soon. It isn’t a blanket problem, however, as different sectors within the chip industry will continue to be affected by the shortage in different ways.

As the industry entered 2020, high demand was expected in the mobile chip area because of the rollout of 5G devices. That path was turned on its head when COVID-19 became a global pandemic, driving millions, if not billions, of people into the safety of their homes to work, go to school, be entertained and to socialize.

Oxygen diatomic molecules have lone-pair electrons and magnetic moments. A high-pressure phase called epsilon oxygen is considered stable in a wide pressure range. This material exhibits the transition to metal at ∼100 GPa (1000, 000× atmospheric pressure). The change in the electronic structure involved in the transition under pressure is difficult to measure using conventional methods. In this study, the electronic structures of oxygen have been successfully measured with oxygen K-edge X-ray Raman scattering spectroscopy. We found a change in the spectra related to the metallization of oxygen. Another change in the electronic structure was also observed at ∼40 GPa. This is likely related to the semimetallic transition.

Electronic structures of dense solid oxygen have been investigated up to 140 GPa with oxygen K-edge X-ray Raman scattering spectroscopy with the help of ab initio calculations based on density functional theory with semilocal metageneralized gradient approximation and nonlocal van der Waals density functionals. The present study demonstrates that the transition energies (Pi*, Sigma*, and the continuum) increase with compression, and the slopes of the pressure dependences then change at 94 GPa. The change in the slopes indicates that the electronic structure changes at the metallic transition. The change in the Pi* and Sigma* bands implies metallic characteristics of dense solid oxygen not only in the crystal a–b plane but also parallel to the c axis. The pressure evolution of the spectra also changes at ∼40 GPa.

Basically, we live in one giant algorithm.

In fascinating new research, cosmologists explain the history of the universe as one of self-teaching, autodidactic algorithms.

This year-old zdnet article notes that the company plans a photo-sensitivi ty range from ultraviolet through visible light to 2000nm infrared. The sensor itself retains almost 4x the light of ordinary CMOS sensors, while being 2000x more sensitive to light. This will put it on par with the best analogue image intensification tubes used for night vision. Up until now, there have not been any digital night vision systems that can match analogue systems. This will be better, with higher resolution and multichromatic. It also has a 100x greater dynamic range than ordinary CMOS sensors, according to the specifications from SeeDevice’s site linked below. (This means that it can image both bright and dark areas clearly and simultaneously, instead of having the bright areas washing out the image, or the dark areas being black. The included photo is from its website, demonstrating a wide dynamic range photo produced by the system. On a normal photo, either the sky would appear black, or the road would be so bright that it would look washed out.)

Hopefully coming soon to a cell phone camera near you…

Microsoft’s acquisition of Nuance signals the tech giant’s AI strategy in Azure, self-driving cars, and other products beyond health care AI.

TerraPower’s ability to achieve those goals will be in no small part due to the money and influence of the company’s founder.

“The most important factor is that Bill Gates is behind this,” principal research scientist at the Massachusetts Institute of Technology department of nuclear science and engineering Charles Forsberg tells CNBC Make It. “The most important factors in developing a new reactor are money and very competent people. Bill Gates brings both to the project.”

Here’s how TerraPower is building advanced nuclear power plants.

**Engineers, using artificial intelligence and wearable cameras, now aim to help robotic exoskeletons walk by themselves.**

Increasingly, researchers around the world are developing lower-body exoskeletons to help people walk. These are essentially walking robots users can strap to their legs to help them move.
