As the amount of data stored in devices and shared over the internet continuously increases, computer scientists worldwide are trying to devise new approaches to secure communications and protect sensitive information. Some of the most well-established and valuable approaches are cryptographic techniques, which essentially encrypt (i.e., transform) data and texts exchanged between two or more parties, so that only senders and receivers can view it in its original form.

Physical unclonable functions (PUFs), devices that exploit “random imperfections” unavoidably introduced during the manufacturing of devices to give physical entities unique “fingerprints” (i.e., trust anchors). In recent years, these devices have proved to be particularly valuable for creating cryptographic keys, which are instantly erased as soon as they are used.

Researchers at Peking University and Jihua Laboratory have recently introduced a new system to generate cryptographic primitives, consisting of two identical PUFs based on aligned carbon nanotube (CNT) arrays. This system, introduced in a paper published in Nature Electronics, could help to secure communications more reliably, overcoming some of the vulnerabilities of previously proposed PUF devices.

Want to mix two fluids? Researchers have developed a path to optimize the stirrer shape and velocity to give the best outcome.

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 magn.

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.
