New paleomagnetic research suggests Earth’s solid inner core formed 550 million years ago and restored our planet’s magnetic field.

Swirling liquid iron in the Earth’s outer core, located approximately 1,800 miles beneath our feet, generates our planet’s protective magnetic field, called the magnetosphere. Although this magnetic field is invisible, it is vital for life on Earth’s surface. That’s because the magnetosphere shields the planet from solar wind—streams of radiation from the sun.

However, about 565 million years ago, the magnetic field’s strength dropped to 10 percent of its strength today. Then, mysteriously, the magnetic field bounced back, regaining its strength just before the Cambrian explosion of multicellular life on Earth.

Why do some individuals always seem to be healthy while other people often get viruses and bacteria? Despite sleeping close to their sick partner every night, how can a sick person’s spouse avoid contracting their illness? During the COVID-19.

First identified in 2019 in Wuhan, China, Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It has spread globally, resulting in the 2019–20 coronavirus pandemic.

Revised Apple patent claims emphasize watching VR users’ gestures, such as facial expressions and head movements.

WASHINGTON — The Defense Innovation Unit is funding space projects that the agency hopes will spur commercial investments in satellite refueling technologies and support services for geostationary satellites.

“Imagine a world where every 18 to 24 months, you could simply upgrade the processor on a satellite in GEO the way that you upgrade your smartphone to take advantage of new processing power and new functionality,” said Steve “Bucky” Butow, director of the space portfolio at the Defense Innovation Unit.

DIU, based in Silicon Valley, is a Defense Department agency established in 2015 to help bring privately funded innovation into military programs.

The European Commission has published its DESI 2022 report, which looks at how much digitalization progress member states are making. It highlighted that the deployment of 5G is going too slow.

DeepMind’s AlphaFold tool has determined the structures of around 200 million proteins, from almost every known organism on Earth.

“The final theory of nature must be octonionic,” observed Michael Atiyah, a British mathematician who united mathematics and physics during the 1960s in a way not seen since the days of Isaac Newton.

“Octonions are to physics what the Sirens were to Ulysses,” Pierre Ramond, a particle physicist and string theorist at the University of Florida, said to Natalie Walchover for Quanta.

Many physicists and mathematicians over the decades suspected that the peculiar panoply of forces and particles that comprise reality spring logically from the properties of eight-dimensional numbers called “octonions.” Proof surfaced in 1,898, writes Walchover in Quanta, that the reals, complex numbers, quaternions and octonions are the only kinds of numbers that can be added, subtracted, multiplied and divided.

A research team led by Rice University neuroengineers has created wireless technology to remotely activate specific brain circuits in fruit flies in under one second.

The team – an assemblage of experts in genetic engineering, nanotechnology, and electrical engineering – used magnetic signals to activate targeted neurons that controlled the body position of freely moving fruit flies in an enclosure.

MIT researchers created protonic programmable resistors — building blocks of analog deep learning systems — that can process data 1 million times faster than synapses in the human brain. These ultrafast, low-energy resistors could enable analog deep learning systems that can train new and more powerful neural networks rapidly, which could be used for areas like self-driving cars, fraud detection, and health care.
