NVIDIA GPUs Enable Simulation of a Living Cell

Posted by in categories: chemistry, computing, genetics, particle physics

Researchers from the University of Illinois developed GPU-accelerated software to simulate a cell that metabolizes and grows like a living cell.


Every living cell contains its own bustling microcosm, with thousands of components responsible for energy production, protein building, gene transcription and more.

Scientists at the University of Illinois at Urbana-Champaign have built a 3D simulation that replicates these physical and chemical characteristics at a particle scale — creating a fully dynamic model that mimics the behavior of a living cell.

Revolutionary Carbon-Based Magnetic Material Finally Synthesized After 70 Years

Posted by in categories: chemistry, materials

Researchers from Osaka University and Osaka City University synthesize and crystallize a molecule that is otherwise too unstable to fully study in the laboratory, and is a model of a revolutionary class of magnets.

Since the first reported production in 2004, researchers have been hard at work using graphene and similar carbon-based materials to revolutionize electronics, sports, and many other disciplines. Now, researchers from Japan have made a discovery that will advance the long-elusive field of nanographene magnets.

In a study recently published in Journal of the American Chemical Society, researchers from Osaka University and collaborating partners have synthesized a crystalline nanographene with magnetic properties that have been predicted theoretically since the 1950s, but until now have been unconfirmed experimentally except at extremely low temperatures.

Quantum Computers Could Crack Bitcoin. Here’s What It Would Take

Posted by in categories: bitcoin, chemistry, cryptocurrencies, cybercrime/malcode, encryption, energy, mathematics, quantum physics, supercomputing

Quantum computers could cause unprecedented disruption in both good and bad ways, from cracking the encryption that secures our data to solving some of chemistry’s most intractable puzzles. New research has given us more clarity about when that might happen.

Modern encryption schemes rely on fiendishly difficult math problems that would take even the largest supercomputers centuries to crack. But the unique capabilities of a quantum computer mean that at sufficient size and power these problems become simple, rendering today’s encryption useless.

That’s a big problem for cybersecurity, and it also poses a major challenge for cryptocurrencies, which use cryptographic keys to secure transactions. If someone could crack the underlying encryption scheme used by Bitcoin, for instance, they would be able to falsify these keys and alter transactions to steal coins or carry out other fraudulent activity.

Novel artificial leaf captures 100 times more carbon than other systems

Posted by in categories: chemistry, energy, engineering

A team of engineers at the University of Illinois Chicago has built a cost-effective artificial leaf that can capture carbon dioxide at 100 times better than current technologies.

This novel artificial leaf works in the real world, unlike other carbon capture systems that could only work with carbon dioxide from pressurized tanks. It captures carbon dioxide from more dilutes sources, like air and flue gas produced by coal-fired power plants, and releases it for use as fuel and other materials.

“Our artificial leaf system can be deployed outside the lab, where it has the potential to play a significant role in reducing greenhouse gases in the atmosphere thanks to its high rate of carbon capture, relatively low cost, and moderate energy, even when compared to the best lab-based systems,” said Meenesh Singh, assistant professor of chemical engineering in the UIC College of Engineering and corresponding author on the paper.

2D Materials could be used to simulate brain synapses in computers

Posted by in categories: chemistry, robotics/AI

Researchers from KTH Royal Institute of Technology and Stanford University have fabricated a material for computer components that enables the commercial viability of computers that mimic the human brain.

Electrochemical random access (ECRAM) memory components made with 2D titanium carbide showed outstanding potential for complementing classical transistor technology, and contributing toward commercialization of powerful computers that are modeled after the brain’s neural network. Such neuromorphic computers can be thousands times more energy efficient than today’s computers.

These advances in computing are possible because of some fundamental differences from the classic computing architecture in use today, and the ECRAM, a component that acts as a sort of synaptic cell in an artificial neural network, says KTH Associate Professor Max Hamedi.

How Lecturers Without Borders Shares The Joy Of Science

Posted by in categories: alien life, chemistry, mathematics, nanotechnology, neuroscience, physics, robotics/AI, science, sustainability

If you are a scientist, willing to share your science with curious teens, consider joining Lecturers Without Borders!


Established by three scientists, Luibov Tupikina, Athanasia Nikolau, and Clara Delphin Zemp, and high school teacher Mikhail Khotyakov, Lecturers Without Borders (LeWiBo) is an international volunteer grassroots organization that brings together enthusiastic science researchers and science-minded teens. LeWiBo founders noticed that scientists tend to travel a lot – for fieldwork, conferences, or lecturing – and realized scientists could be a great source of knowledge and inspiration to local schools. To this end, they asked scientists to volunteer for talks and workshops. The first lecture, delivered in Nepal in 2017 by two researchers, a mathematician and a climatologist, was a great success. In the next couple of years, LeWiBo volunteers presented at schools in Russia and Belarus; Indonesia and Uganda; India and Nepal. Then, the pandemic forced everything into the digital realm, bringing together scientists and schools across the globe. I met with two of LeWiBo’s co-founders, physicist Athanasia Nikolaou and math teacher Mikhail Khotyakov, as well as their coordinator, Anastasia Mityagina, to talk about their offerings and future plans.

Julia Brodsky: So, how many people volunteer for LeWiBo at this time?

Upcycled adhesive is one of the toughest materials ever reported

Posted by in categories: chemistry, nanotechnology

The strong new adhesive is the handiwork of scientists at the US Department of Energy’s Oak Ridge National Laboratory (ORNL), who used polystyrene-b-poly(ethylene-co-butylene)-b-polystyrene, or SEBS, as their starting point. This rubbery polymer can be found in toothbrushes, handlebar grips and diapers, and the researchers were able to equip it with powerful new capabilities by making tweaks to its chemical structure.

This was achieved through a process known as dynamic crosslinking, which enables the bridging of typically incompatible materials. The scientists used the technique to couple silica nanoparticles and the polymer with the help of compounds called boronic esters, resulting in a novel crosslinked composite material they’ve called SiNP. The boronic esters are key to the reusability of the adhesive, as they enable the crosslinked bonds to be formed and broken repeatedly.
