Can you imagine sound traveling in the same way as light does? A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: The airborne sound wave vibrates transversely and carries both spin and orbital angular momentum like light does. The findings shattered scientists’ previous beliefs about the sound wave, opening an avenue to the development of novel applications in acoustic communications, acoustic sensing and imaging.

The research was initiated and co-led by Dr. Shubo Wang, Assistant Professor in the Department of Physics at CityU, and conducted in collaboration with scientists from Hong Kong Baptist University (HKBU) and the Hong Kong University of Science and Technology (HKUST). It was published in Nature Communications, titled “Spin-orbit interactions of transverse sound.”

Warp drive pioneer Dr. Harold G “Sonny” White has reported the successful manifestation of an actual, real-world “Warp Bubble.”

Warp drive pioneer and former NASA warp drive specialist Dr. Harold G “Sonny” White has reported the successful manifestation of an actual, real-world “Warp Bubble.” And, according to White, this first of its kind breakthrough by his Limitless Space Institute (LSI) team sets a new starting point for those trying to manufacture a full-sized, warp-capable spacecraft.

“To be clear, our finding is not a warp bubble analog, it is a real, albeit humble and tiny, warp bubble,” White told The Debrief, quickly dispensing with the notion that this is anything other than the creation of an actual, real-world warp bubble. “Hence the significance.”

Theoretical physicist Sean Carroll joins us to discuss whether it make sense to think of consciousness as an emergent phenomenon, and whether contemporary physics points in this direction.

We discussed Sean’s essay responding to Philip’s book ‘Galileo’s Error,’ and Philip’s counter-response essay. Both are available here: https://conscienceandconsciousness.com/2021/08/01/19-essays-on-galileos-error/

A scientist who loves to write, can do it well, and can share the excitement of the scientific pursuit is incredibly rare. Kevin Peter Hand 0, Deputy Project Scientist, Europa and Director of the JPL Ocean Worlds Lab is that rare person who can do all these things. In his incredible book Alien Oceans: The Search for Life in the Depths of Space 0, he explains that “We know that the laws of physics, the principles of chemistry, and the principles of geology all work beyond Earth. We’ve explored other worlds and observed that these sciences are universal. When it comes to biology, however, we have yet to make that leap.”

If you want to learn about how the intersection of numerous areas of science are helping inform our understanding of the oceans, space, and ourselves, Alien Oceans is by far one of the most clearly written books on the topic. As Kevin notes, he wrote the book he wishes he could have read in college. Kevin will teach you and inspire you and explain complicated scientific topics in ways nearly anyone can understand. Not only is it a book about his areas of expertise, it is also a wonderful window into the way scientists and engineers think about solving real world problems and applying basic knowledge. For example, Kevin notes in this interview that “Making measurements is where the creativity of science meets the hard reality of engineering.” I read a lot of books on science written for a broad audience, and this book, by far is among the very best I have ever read. More than anything else what came through in Kevin’s writing is excitement about finding out what is true.

The involvement between electron transfer (ET) and catalytic reaction at electrocatalyst surface makes electrochemical process challenging to understand and control. How to experimentally determine ET process occurring at nanoscale is important to understand the overall electrochemical reaction process at active sites.

Recently, a research group led by Prof. LI Can and Prof. FAN Fengtao from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) captured the electron transfer imaging in electrocatalysis process.

This study was recently published in the journal Nano Letters.

Its exact hardness remained unknown — until now.

Growing Diamonds

Researchers from Washington State University’s Institute for Shock Physics have developed hexagonal diamonds large enough to study in a lab and test their stiffness and hardness.

A multi-institutional team of astrophysicists headquartered at Boston University, led by BU astrophysicist Merav Opher, has made a breakthrough discovery in our understanding of the cosmic forces that shape the protective bubble surrounding our solar system—a bubble that shelters life on Earth and is known by space researchers as the heliosphere.

Astrophysicists believe the heliosphere protects the planets within our solar system from powerful radiation emanating from supernovas, the final explosions of dying stars throughout the universe. They believe the heliosphere extends far beyond our solar system, but despite the massive buffer against cosmic radiation that the heliosphere provides Earth’s life-forms, no one really knows the shape of the heliosphere—or, for that matter, the size of it.

“How is this relevant for society? The bubble that surrounds us, produced by the sun, offers protection from galactic cosmic rays, and the shape of it can affect how those rays get into the heliosphere,” says James Drake, an astrophysicist at University of Maryland who collaborates with Opher. “There’s lots of theories but, of course, the way that galactic cosmic rays can get in can be impacted by the structure of the heliosphere—does it have wrinkles and folds and that sort of thing?”

Physicists propose an new exponential growth mechanism for dark matter creation.

SPARC is aiming to be the first experimental device to achieve an energy-positive fusion reaction. New research suggests that this goal may soon be within reach.

With construction slated to begin in spring 2021, the team predicts it could be built within 3 to 4 years from that. Their goal is to achieve a Q factor of at least 2, basically meaning SPARC will pump out twice the energy needed to power it.
