Move aside, electrons; it’s time to make way for the trion.

A research team led by physicists at the University of California, Riverside, has observed, characterized, and controlled dark trions in a semiconductor—ultraclean single-layer tungsten diselenide (WSe₂)—a feat that could increase the capacity and alter the form of information transmission.

In a semiconductor, such as WSe₂, a trion is a quantum bound state of three charged particles. A negative trion contains two electrons and one hole; a positive trion contains two holes and one electron. A hole is the vacancy of an electron in a semiconductor, which behaves like a positively charged particle. Because a trion contains three interacting particles, it can carry much more information than a single electron.

Physicists at the University of Innsbruck are proposing a new model that could demonstrate the supremacy of quantum computers over classical supercomputers in solving optimization problems. In a recent paper, they demonstrate that just a few quantum particles would be sufficient to solve the mathematically difficult N-queens problem in chess even for large chess boards.

A process called nucleation plays a critical role in many physical and biological phenomena that range from crystallization, melting and evaporation to the formation of clouds and the initiation of neurodegenerative diseases. However, nucleation is a challenging process to study experimentally, especially in its early stages, when several atoms or molecules start to form a new phase from a parent phase. Now, a team of physicists led by the University of California, Los Angeles has used a method called atomic electron tomography to study early-stage nucleation in four dimensions (that is, in three dimensions of space and across time) at atomic resolution.

As evidence grows that gut bacteria play roles in the development and persistence of food allergies, researchers begin to explore microbe-based interventions.

Malware researchers discovered a new malicious campaign for Android devices that replaces legitimate apps with tainted copies built to push advertisements or hijack valid ad events.

Around 25 million devices have already been infected with what researchers have dubbed “Agent Smith,” after users installed an app from an unofficial Android store.

Forms of Transhumanism

Transhumanism takes a variety of overlapping forms united around a common commitment to use science and technology to improve human intellect and/or physiology. Many, though not all, are committed to Posthumanism; others focus on artificial intelligence and its implications for human life. All of them raise important worldview questions, though not always the same ones.

Carbon dioxide is kind of painted as the villain of the 21st century, and it’s not enough to just reduce our emissions now – we need to remove some of what’s already in the atmosphere. Now, researchers at Karlsruhe Institute of Technology (KIT) have developed a simple way to turn the troublesome gas into a useful resource by converting it into the “wonder” material graphene.

Astaroth is, as demonologists will tell you, the Great Duke of Hell and part of the evil trinity. Microsoft, however, is warning that Astaroth malware is attacking Windows users with a fileless “invisible man” methodology. Here’s what you need to know.

Virgin Galactic is preparing to become the first publicly traded spaceflight company, and the venture is setting a course to be profitable by August 2021, which would put it lightyears ahead of the profitability projections of another transportation-based company that simply moves people around on Earth: Uber.

The Wall Street Journal reports that Virgin Galactic is merging with Social Capital Hedosophia Holdings (SCH), which will take a 49 percent stake and invest about $800 million into the space tourism endeavor.
