The digital device you are using to view this article is no doubt using the bit, which can either be 0 or 1, as its basic unit of information. However, scientists around the world are racing to develop a new kind of computer based on the use of quantum bits, or qubits, which can simultaneously be 0 and 1 and could one day solve complex problems beyond any classical supercomputers.

A research team led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, in close collaboration with FAMU-FSU College of Engineering Associate Professor of Mechanical Engineering Wei Guo, has announced the creation of a new qubit platform that shows great promise to be developed into future quantum computers. Their work is published in the journal Nature.

“Quantum computers could be a revolutionary tool for performing calculations that are practically impossible for classical computers, but there is still work to do to make them reality,” said Guo, a paper co-author. “With this research, we think we have a breakthrough that goes a long way toward making qubits that help realize this technology’s potential.”

Researchers at Princeton University have built the world’s smallest mechanically interlocked biological structure, a deceptively simple two-ring chain made from tiny strands of amino acids called peptides.

In a paper published August 23 in Nature Chemistry, the team detailed a library of such structures made in their lab—two interlocked rings, a ring on a dumbbell, a daisy chain and an interlocked double lasso—each around one billionth of a meter in size. The study also demonstrates that some of these structures can toggle between at least two shapes, laying the groundwork for a biomolecular switch.

“We’ve been able to build a bunch of structures that no one’s been able to build before,” said A. James Link, professor of chemical and biological engineering, the study’s principal investigator. “These are the smallest threaded or interlocking structures you can make out of peptides.”

The complex aerodynamics around a moving car and its tires are hard to see, but not for some mechanical engineers.

Specialists in fluid dynamics at Rice University and Waseda University in Tokyo have developed their computer simulation methods to the point where it’s possible to accurately model moving cars, right down to the flow around rolling tires.

Russian scientists have synthesized a new ultra-hard material consisting of scandium containing carbon. It consists of polymerized fullerene molecules with scandium and carbon atoms inside. The work paves the way for future studies of fullerene-based ultra-hard materials, making them a potential candidate for photovoltaic and optical devices, elements of nanoelectronics and optoelectronics, and biomedical engineering as high-performance contrast agents. The study was published in Carbon.

The discovery of new, all-carbon molecules known as fullerenes almost 40 years ago was a revolutionary breakthrough that paved the way for fullerene nanotechnology. Fullerenes have a spherical shape made of pentagons and hexagons that resembles a soccer ball, and a cavity within the carbon frame of fullerene molecules can accommodate a variety of atoms.

The introduction of metal atoms into carbon cages leads to the formation of endohedral metallofullerenes (EMF), which are technologically and scientifically important owing to their unique structures and optoelectronic properties.

The cellular forms of natural materials are the inspiration behind a new lightweight, 3D printed smart architected material developed by an international team of engineers.

The team, led by engineers from the University of Glasgow, mixed a common form of industrial plastic with carbon nanotubes to create a material which is tougher, stronger and smarter than comparable conventional materials.

The nanotubes also allow the otherwise nonconductive plastic to carry an electric charge throughout its structure. When the structure is subjected to mechanical loads, its electrical resistance changes. This phenomenon, known as piezoresitivity, gives the material the ability to “sense” its structural health.

The results of the study could lead to new treatment options. In a groundbreaking new study published in the journal Nature on Thursday, researchers have compared the brain cells of patients who had died from either Parkinson’s disease or dementia to people unaffected by the disorders and found which brain cells are responsible for both conditions.

A team of researchers has created a bacteria that can produce a steady and consistent source of medicine inside a patient’s gut, suggesting the possibility for genetically edited bacteria to be an efficient Parkinson’s disease treatment.

Mangrove trees inspire thermal and membrane-based desalination system.

Four US students, taking part in a program aimed at high school girls interested in engineering, have designed a desalinating water bottle. The currently hypothetical device would be compact and portable so could offer increased accessibility over existing desalinating designs that mimic transpiration.

Laurel Hudson, Gracie Cornish, Kathleen Troy and Maia Vollen met at Virginia Tech’s C-Tech2 program where they were given an assignment to ‘reinvent the wheel’. Choosing to focus on the global water crisis and inspired by drinking straws used by hikers to purify water, they considered if it was possible to make a bottle that produced drinking water from seawater. They reached out to Jonathan Boreyko, an associate professor in the department of mechanical engineering, who was researching synthetic trees at the time. He agreed to help, and, during the height of the Covid-19 pandemic, the group met virtually at night to discuss their research. Along with Ndidi Eyegheleme, a graduate student in Boreyko’s lab, they planned and produced a model to evaluate the inner workings of their design.
