Sound waves, like an invisible pair of tweezers, can be used to levitate small objects in the air. Although DIY acoustic levitation kits are readily available online, the technology has important applications in both research and industry, including the manipulation of delicate materials like biological cells.

Researchers at the University of Technology Sydney (UTS) and the University of New South Wales (UNSW) have recently demonstrated that in order to precisely control a particle using ultrasonic waves, it is necessary to take into account both the shape of the particle and how this affects the acoustic field. Their findings were recently published in the journal Physical Review Letters.

Sound levitation happens when sound waves interact and form a standing wave with nodes that can ‘trap’ a particle. Gorkov’s core theory of acoustophoresis, the current mathematical foundation for acoustic levitation, makes the assumption that the particle being trapped is a sphere.

Summary: A new study links daily eating to mortality risk. Those over 40 who eat one meal a day have a higher mortality risk. Those who skip breakfast are at an increased risk of cardiovascular disease-associated death, and those who eat meals less than 4.5 hours apart have increased mortality risks.

Eating only one meal per day is associated with an increased risk of mortality in American adults 40 years old and older, according to a new study in the Journal of the Academy of Nutrition and Dietetics.

The information security landscape is rapidly changing in response to quantum computing technology, which is capable of cracking modern encryption techniques in minutes, but a promising US government encryption algorithm for the post-quantum world was just cracked in less than an hour thanks to a decades-old math theorem.

In July 2022, the US National Institute of Standards and Technology (NIST) chose a set of encryption algorithms that it hoped would stand up to the encryption-cracking power of quantum computers and tasked researchers with probing them for vulnerabilities, offering a $50,000 prize for anyone who was able to break the encryption.

The new AI art software brings “brand new possibilities for creative applications.”

London and San Francisco-based Stability AI, the company that developed Stable Diffusion, an image-generating open-source AI software, has just announced the release of Stable Diffusion 2.0, as per a press statement on the company’s website.

What is Stable Diffusion?

“Science is for everyone and space travel hopefully can be for everyone.”

The European Space Agency (ESA) named the first-ever “parastronaut” this week on Wednesday, Nov. 23, meaning the world may soon see the first disabled person go to space.

The agency, made up of 22 nations, chose former British Paralympic sprinter John McFall among 16 other new recruits for astronaut training.

We strongly believe that culture meat is an engine of change.

Have you ever tried cultivated meat before? If not, what you’re about to learn will make you want to. Let us introduce you to Believer Meats, formerly known as Future Meat Technologies.

Established in 2018, the company says, “the only difference is that it’s been grown in a lab from high-quality, non-GMO animal cells. The result is meat that doesn’t require compromising on taste, quality, or environmental impact. It’s time to enjoy meat that’s as good for you as it is for the world.”

Graphics Processing Units are not just resolution on a monitor.

The Graphics Processing Unit was first developed in the 1970s (think Pong)There are two types of GPUs, on a separate card and embedded in a CPU chip.

Today’s GPUs are so sophisticated they work in parallel to the CPU doing many tasks the CPU handles.

It is essential to understand how lightning works so that buildings, airplanes, skyscrapers, and people can be protected more effectively.

Ever wondered why lightning zig-zags? Or how it is connected to the thundercloud ago? You might have tried looking up the many textbooks on the lightning but failed to find a definite and convincing answer.

The finding could have implications on drug development beyond neuroscience.

A new study conducted by researchers at the University of Copenhagen has found that V-ATPase, an enzyme thought to be a key component of brain function, switches off randomly, even for hours at a time. This discovery has the potential to change our understanding of how our brain functions, according to a press release.

V-ATPase is an enzyme that can break down ATP molecules, the cell’s energy currency, as they pump protons across cellular membranes.
