‘Inspired by the human brain’: Intel debuts neuromorphic system that aims to mimic grey matter with a clear aim — making the machine exponentially faster and much more power efficient, just like us

Posted by in categories: computing, neuroscience

Neuromorphic computing is about mimicking the human brain’s structure to deliver more efficient data processing, including faster speeds and higher accuracy, and it’s a hot topic right now. A lot of universities and tech firms are working on it, including scientists at Intel who have built the world’s largest “brain-based” computing system for Sandia National Laboratories in New Mexico.

Intel’s creation, called Hala Point, is only the size of a microwave, but boasts 1.15 billion artificial neurons. That’s a massive step up from the 50 million neuron capacity of its predecessor, Pohoiki Springs, which debuted four years ago. There’s a theme with Intel’s naming in case you were wondering – they’re locations in Hawaii.

Scientists hail ‘exciting’ material that can store greenhouse gases

Posted by in category: materials

Scientists have hailed the “exciting” discovery of a type of porous material that can store carbon dioxide.

The research, published in the journal Nature Synthesis, saw a team led by scientists at Heriot-Watt University in Edinburgh create hollow, cage-like molecules with high storage capacities for greenhouse gases like carbon dioxide and sulphur hexafluoride. Sulphur hexafluoride is a more potent greenhouse gas than carbon dioxide and can last thousands of years in the atmosphere.

China Shows Off Monkey With Brain Chip Allowing It to Control Robotic Arm

Posted by in categories: Elon Musk, government, neuroscience, robotics/AI

A Chinese company says it’s successfully developed a brain chip and implanted it into a monkey — who can now remotely control a robot arm with the device.

That’s according to state-run news media outfit Xinhua, putting Elon Musk’s startup Neuralink on notice that there will be international as well as domestic competition for his brain-computer interface venture.

The company, Beijing Xinzhida Neurotechnology, which is backed by the Chinese government, unveiled its device, the NeuCyber Array BMI (brain-machine interface) System at a technology convention in Beijing on Thursday, according to Reuters.

Bolometer measures state of superconducting qubit

Posted by in categories: computing, quantum physics

For this technique to work at very high fidelity, a very fast and very sensitive bolometer is needed to measure the quantum state before it decays. In 2020, the Finnish researchers unveiled a bolometer that used graphene as its absorber – a fast and sensitive design that was intended for use in quantum computing. Unfortunately, this bolometer degraded over time and the team instead used an older bolometer design involving interfaces between superconductors and normal metals.

Möttönen says that the researchers had initially not expected the older design to be effective for reading out the states of individual qubits. He also expects that the read-out fidelity could be boosted using improved graphene bolometers. “I’m hoping to get the new graphene bolometers out of the oven soon,” he says.

David Pahl at the Massachusetts Institute of Technology believes that the work is very preliminary, but potentially very important. He says that the two most important performance metrics for a scheme to read out quantum states are the fidelity and the speed: “The state of the art speed that we’ve seen in the past year is 0.1 μs and 99.5% fidelity…[Möttönen and colleagues] showed 14 μs and 61.7%,” he says.

Researchers have developed tiny, flexible devices that can wrap around individual nerve fibers without damaging them.

The researchers, from the University of Cambridge, combined flexible electronics and soft robotics techniques to develop the devices, which could be used for the diagnosis and treatment of a range of disorders, including epilepsy and chronic pain, or the control of prosthetic limbs.

The first reverse microwave in the U.S.: you can have it at home to save energy while cooking

Posted by in categories: energy, food

Scientific and technical research in the United States has led to decades of progress in energy efficiency, as we have seen on previous occasions. However, we have just learned of a breakthrough that was only theorized until now, finally, it has been put into operation. This is the first-ever reverse microwave, which cools food instead of heating it. Could you simply imagine that?

A reverse microwave is an innovative appliance that rapidly cools food and drinks without using electricity. Unlike a traditional microwave oven which uses microwave radiation to heat items, a reverse microwave utilizes thermoelectric cooling.

This technology allows the reverse microwave to draw heat away from the contents inside, lowering their temperature in just minutes. The concept behind reverse microwaves has existed for decades, but the technology is only now becoming available for home use in the United States.

Here Are The Rarest Remaining Celestial Events Of Your Life

Posted by in category: futurism

What’s the rarest celestial event you have ever seen? With a total solar eclipse in very recent history for the U.S, is possible that you have already had a once in a lifetime experience where you live. However, the night sky has some spectacular sites, some of which will never happen again in your lifetime, but some that will—and some of them soon.

Here are some of the rarest events you can expect to see in the next four decades.

Scientists learn from caterpillars how to create self-assembling capsules for drug delivery

Posted by in categories: biotech/medical, nanotechnology

Self-assembling molecules that spontaneously organize themselves to form complex structures are common in nature. For example, the tough outer layer of insects, called the cuticle, is rich in proteins that can self-assemble.

Self-assembly is a cost-effective, environmentally sustainable and quick way of manufacturing nanostructures with critical applications in various industries, ranging from therapeutics to self-replicating machines.

Harnessing the self-assembling abilities of proteins from the cuticles of Asian corn borer moth caterpillars (Ostrinia furnacalis), Nanyang Technological University, Singapore (NTU Singapore) scientists have created nanosized capsules that could be used to deliver drugs and messenger RNA (mRNA). mRNA is a molecule that instructs cells to produce proteins and has been used in COVID-19 vaccines.

The Novel Material Revolutionizing Energy Storage

Posted by in categories: biotech/medical, computing, mobile phones

Washington University in St. Louis scientists have developed a novel material that supercharges innovation in electrostatic energy storage. The material is built from artificial heterostructures made of freestanding 2D and 3D membranes that have an energy density up to 19 times higher than commercially available capacitors.

Electrostatic capacitors play a crucial role in modern electronics. They enable ultrafast charging and discharging, providing energy storage and power for devices ranging from smartphones, laptops, and routers to medical devices, automotive electronics and industrial equipment. However, the ferroelectric materials used in capacitors have significant energy loss due to their material properties, making it difficult to provide high energy storage capability.
