A team of physicists at the University of Edinburgh’s School of Physics and Astronomy has used mathematical calculations to show that quantum communications across interstellar space should be possible. In their paper published in the journal Physical Review D, the group describes their calculations and also the possibility of extraterrestrial beings attempting to communicate with us using such signaling.

Over the past several years, scientists have been investigating the possibility of using quantum communications as a highly secure form of message transmission. Prior research has shown that it would be nearly impossible to intercept such messages without detection. In this new effort, the researchers wondered if similar types of communications might be possible across interstellar space. To find out, they used math that describes that movement of X-rays across a medium, such as those that travel between the stars. More specifically, they looked to see if their calculations could show the degree of decoherence that might occur during such a journey.

With quantum communications, engineers are faced with quantum particles that lose some or all of their unique characteristics as they interact with obstructions in their path—they have been found to be quite delicate, in fact. Such events are known as decoherence, and engineers working to build quantum networks have been devising ways to overcome the problem. Prior research has shown that the space between the stars is pretty clean. But is it clean enough for quantum communications? The math shows that it is. Space is so clean, in fact, that X-ray photons could travel hundreds of thousands of light years without becoming subject to decoherence—and that includes gravitational interference from astrophysical bodies. They noted in their work that optical and microwave bands would work equally well.

Aging (Aging-US) and FOXO Technologies have teamed up to present a special collaboration on aging research with a new monthly video series: the Longevity & Aging Series. This series of video interviews invites Aging researchers to speak with researcher and host Dr. Brian Chen. Dr. Chen is an adjunct faculty member at the Herbert Wertheim School of Public Health and Human Longevity Science at the University of California San Diego. He is also the Chief Science Officer of FOXO Technologies.

The Large Hadron Collider detectors started recording high-energy collisions at the unprecedented energy of 13.6 TeV.

The Large Hadron Collider is once again delivering proton collisions to experiments, this time at an unprecedented energy of 13.6 TeV, marking the start of the accelerator’s third run of data taking for physics.

A burst of applause erupted in the CERN.

We’ve learned about a few techniques in biotechnology already, but the CRISPR-Cas9 system is one of the most exciting ones. Inspired by bacterial immune response to viruses, this site-specific gene editing technique won the Nobel prize in chemistry in 2020, going to Jennifer Doudna and Emmanuelle Charpentier. How did they develop this method? What can it be used for? Let’s get the full story!

A team of researchers at the European Council for Nuclear Research (CERN) has discovered three new composite particles from observations made through the Large Hadron Collider – the world’s most powerful particle accelerator located in Switzerland and France. The discovery included a pair of tetraquarks and a pentaquark – thereby showcasing an even wider range of ways in which fundamental particles of the universe can interact with each other.

A quark is a fundamental particle, which means that it has no further known subdivisions in particle physics, as of now. Quarks, along with electrons, form the building blocks of all matter in the universe. A combination of multiple quarks is known as a hadron, which include two type – the positively charged proton and the neutral neutron.

While quarks have commonly been observed to come in combinations of twos and threes, the newly discovered hadrons are being referred to as “exotic” by the scientists because they feature four and five quarks in them. These particles are called ‘composite particles’, since they are composed of smaller fundamental building blocks – the quarks themselves.

Understanding what’s inside of a planet is like trying to figure out what’s inside of a gift without unwrapping it. But because we can’t simply tear open a planet, instead, we must rely on secondary evidence, like the waves generated by geologic events.

Seismology — the study of quakes and seismic waves — lets us take “images” of the interiors of planets. NASA’s Viking landers brought the first seismometers to Mars in 1976, but they were plagued by noise, which rendered them largely ineffective. It took more than 40 years until Mars hosted another mission equipped with a quake-measuring instrument: NASA’s InSight lander.

And although InSight is expected to retire later this year, ever since the lander touched down in 2018, this stationary surveyor has been studying marsquakes, slowly unveiling the interior of the Red Planet.

A lot of heat gets lost during the conversion of energy. Estimates even put it at more than 70%. However, in thermoelectric materials, such as those being studied at the Institute of Solid State Physics at TU Wien, heat can be converted directly into electrical energy. This effect (the Seebeck effect) can be used in numerous applications in industry but also in everyday life.

Recently, Ernst Bauer’s research team made an exciting discovery in a thermoelectric material consisting of iron, vanadium and aluminum (Fe₂VAl). The researchers recently published their results in Nature Communications.

China is emerging as a pioneer in artificial intelligence as it makes strides in filing AI patents and experimenting with the latest AI technology to power industrial applications, industry experts said.

Their comments came after a Stanford University report that shows China filed more than half of all the world’s AI patent applications last year and Chinese researchers produced about one-third of AI journal papers and AI citations in 2021.

Wu Hequan, an academician at the Chinese Academy of Engineering, said China has been working to build a solid foundation to support its AI economy and is making significant contributions to AI globally.

Interpreting magnetic resonance images in the context of network control theory, researchers seek to explain the brain’s dynamics in terms of its structure, information content, and energetics.
