In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles.

Because this behavior is hypothesized to be perpetual, the universe should have no beginning and no end—only eternal cycles of growing and shrinking that extend forever into the future, and forever into the past.

It’s an appealing concept in part because it removes the need for a state called a singularity that corresponds to “beginning of time” in other models.

A research team led by the Technical University of Munich (TUM) has succeeded for the first time in producing a molecular electric motor using the DNA origami method. The tiny machine made of genetic material self-assembles and converts electrical energy into kinetic energy. The new nanomotors can be switched on and off, and the researchers can control the rotation speed and rotational direction.

Be it in our cars, drills or automatic coffee grinders—motors help us perform work in our everyday lives to accomplish a wide variety of tasks. On a much smaller scale, natural molecular motors perform vital tasks in our bodies. For instance, a motor protein known as ATP synthase produces the molecule adenosine triphosphate (ATP), which our body uses for short-term storage and transfer of energy.

While natural molecular motors are essential, it has been quite difficult to recreate motors on this scale with mechanical properties roughly similar to those of natural molecular motors like ATP synthase. A research team has now constructed a working nanoscale molecular rotary motor using the DNA origami method and published their results in Nature. The team was led by Hendrik Dietz, Professor of Biomolecular Nanotechnology at TUM, Friedrich Simmel, Professor of Physics of Synthetic Biological Systems at TUM, and Ramin Golestanian, director at the Max Planck Institute for Dynamics and Self-Organization.

Holographic teleportation is when a hologram is transmitted to a different location instantaneously.

While it is something that was only seen in SciFi movies like Star Wars, on July 27 at the Western Institute for Space Exploration (Western Space), the world’s first-ever international holoport was demonstrated.

Summary: Zooming out to image larger areas of the brain while using fMRI technology allows researchers to capture additional relevant information, offering a better understanding of neural interplay.

Researchers have learned a lot about the human brain through functional magnetic resonance imaging (fMRI), a technique that can yield insight into brain function. But typical fMRI methods may be missing key information and providing only part of the picture, Yale researchers say.

Here are my thoughts on attending the 2022 Tesla Annual Shareholders Meeting.

Just as human counts are incomplete, so are animal counts. But the first worldwide compilation of animal cases is a start at understanding the extent of human-to-animal transmission, scientists say.

The researchers wanted to create robots that could pick up and sort molecules within a designated space. This makes it possible for DNA molecules to serve as the building blocks for 3D nanostructures that self-assemble in a predetermined shape. Tiny DNA-based robots and other nanodevices will deliver medicine inside our bodies, detect the presence of deadly pathogens, and help manufacture increasingly smaller electronics.

This enabled the researchers to design a nano-robot composed of three DNA origami structures. To help it maneuver within the designated space, the robot had a “leg” with a pair of feet. An “arm” with a “hand” allowed it to carry cargo, and a third component was added to tell the hand when a specific drop-off point had been reached so it would know to release the cargo. It allows researchers to carry out the entire design truly in 3D. Earlier design tools only allowed creation in 2D, forcing researchers to map their creations into 3D.

The software helps researchers design ways to take tiny strands of DNA and combine them into complex structures with parts like rotors and hinges that can move and complete a variety of tasks, including drug delivery. The robot will also enable researchers to more precisely determine important signaling pathways for a variety of biological and pathological processes that are stimulated at the cellular level during the application of force.

Holographic teleportation could solve the many issues that 2D virtual meetings have these days. Besides, you could simply beam into work while at home.

Researchers at the University of Western Ontario recently completed the world’s first-ever international holographic teleportation.

In the past, the city relied on complaints to identify people not following the rules, but new digital water meters installed city wide means the city doesn’t have to wait for someone to call.

The meters send water data back wirelessly. Customers can now monitor their daily and hourly water use through an app, alerting them to high usage rates or leaks.

The city though is also able to see high use rates at times when it doesn’t add up. Rates of 300-gallons per hour on a Monday, indicated someone probably had the sprinklers on, triggering a notice.
