Oxford spinoff demonstrates world-first hypersonic “projectile fusion”

Posted by in categories: nuclear energy, particle physics

Oxford spinoff First Light Fusion says its novel “projectile” approach offers “the fastest, simplest and cheapest route to commercial fusion power.” The company is now celebrating a significant breakthrough with its first confirmed fusion reaction.

The nuclear fusion space is heating up, if you’ll pardon the pun, as the world orients itself toward a clean energy future. Where current nuclear power plants release energy by splitting atoms in fission reactions, fusion reactors will release energy in the same way the Sun does – by smashing atoms together so hard and so fast that they fuse into higher elements.

Physicists Found a Way to Mimic Neutron Stars in the Lab

Posted by in categories: physics, space

Using a “laser pincer,” scientists can generate their own antimatter, simulations show.


An international team of physicists have come up with a way to generate antimatter in the lab, allowing them to recreate conditions that are similar to those near a neutron star.

This setup, at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) research laboratory in Germany, involves two high-intensity laser beams that can generate a jet of antimatter, as outlined in a paper published earlier this summer in the journal Communications Physics. That could make antimatter-based research far more accessible for scientists around the world.

The side effects of quantum error correction and how to cope with them

Posted by in categories: habitats, quantum physics

It is well established that quantum error correction can improve the performance of quantum sensors. But new theory work cautions that unexpectedly, the approach can also give rise to inaccurate and misleading results—and shows how to rectify these shortcomings.

Quantum systems can interact with one another and with their surroundings in ways that are fundamentally different from those of their classical counterparts. In a quantum sensor, the particularities of these interactions are exploited to obtain characteristic information about the environment of the quantum system—for instance, the strength of a magnetic and electric field in which it is immersed. Crucially, when such a device suitably harnesses the laws of quantum mechanics, then its sensitivity can surpass what is possible, even in principle, with conventional, classical technologies.

Unfortunately, quantum sensors are exquisitely sensitive not only to the physical quantities of interest, but also to noise. One way to suppress these unwanted contributions is to apply schemes collectively known as quantum error correction (QEC). This approach is attracting considerable and increasing attention, as it might enable practical high-precision quantum sensors in a wider range of applications than is possible today. But the benefits of error-corrected quantum sensing come with major potential side effects, as a team led by Florentin Reiter, an Ambizione fellow of the Swiss National Science Foundation working in the group of Jonathan Home at the Institute for Quantum Electronics, has now found. Writing in Physical Review Letters, they report theoretical work in which they show that in realistic settings QEC can distort the output of quantum sensors and might even lead to unphysical results.

Could a computer ever learn the same way people and animals do?

Posted by in categories: bioengineering, biotech/medical, robotics/AI

Whether a computer could ever pass for a living thing is one of the key challenges for researchers in the field of Artificial Intelligence. There have been vast advancements in AI since Alan Turing first created what is now called the Turing Test—whether a machine could exhibit intelligent behavior equivalent to, or indistinguishable from, that of a human. However, machines still struggle with one of the fundamental skills that is second nature for humans and other life forms: lifelong learning. That is, learning and adapting while we’re doing a task without forgetting previous tasks, or intuitively transferring knowledge gleaned from one task to a different area.

Now, with the support of the DARPA Lifelong Learning Machines (L2M) program, USC Viterbi researchers have collaborated with colleagues at institutions from around the U.S. and the world on a new resource for the future of AI learning, defining how artificial systems can successfully think, act and adapt in the real world, in the same way that living creatures do.

The paper, co-authored by Dean’s Professor of Electrical and Computer Engineering Alice Parker and Professor of Biomedical Engineering, and of Biokinesiology and Physical Therapy, Francisco Valero-Cuevas and their research teams, was published in Nature Machine Intelligence, in collaboration with Professor Dhireesha Kudithipudi at the University of Texas at San Antonio, along with 22 other universities.

Amazon Secures Up to 83 Launches from Arianespace, Blue Origin, and United Launch Alliance for Project Kuiper

Posted by in categories: internet, satellites

Amazon calls it “the largest commercial procurement of launch vehicles in history.” Amazon’s SpaceX-rivaling internet service Project Kuiper has made a major leap towards becoming operational and catching up with SpaceX’s Starlink, which is already populating our skies.


Amazon selects Arianespace, Blue Origin, and ULA as heavy-lift launch partners to deploy the majority of its Project Kuiper satellite constellation.

Taiwan’s New Solar Panel ‘Sun Rock’ Will Deliver 1 Million kWh Per Year

Posted by in categories: government, solar power, sustainability

Get in, we’re going to the threshold. Solar power is undoubtfully one of the most preferred renewable energy sources of the day. As the need for energy rises with the improving technology and the rising population, companies try to come up with the most efficient solutions that promise to meet the energy demand of the world.


Taiwan’s forthcoming Sun Rock could supply excess energy to the power grid

Taiwan’s government-owned power company, called Taipower, commissioned Sun Rock, with plans to use it as a visitor facility, in addition to a storage and maintenance center for renewable energy devices. But the most obvious and impressive feature of the forthcoming project is the facade, which will be almost totally smothered in solar panels (don’t worry, there will also be vents and windows to promote the natural exchange of light and air). But 1 million kWh is a lot — the U.S. government has found that an average household uses roughly 11,000 kWh annually, which will rise (because of course it will) before the Sun Rock is finished.
