In a new FLEET theoretical study published recently in Physical Review Letters, the so called ‘smoking gun’ in the search for the topological magnetic monopole — also known as the Berry curvature — has been found.

The discovery is a breakthrough in the search for topological effects in non-equilibrium systems.

The group, led by UNSW physicist and Associate Professor, Dimi Culcer, identified an unconventional Hall effect, driven by an in-plane magnetic field in semiconductor hole systems that can be traced exclusively to the Berry curvature.

China has tested a weapon that was previously thought impossible, according to a new report.

The hypersonic weapon test saw the country fire a missile from another spacecraft that was already flying at least five times the speed of sound, the report claimed. Such technology was previously thought impossible and US experts are unsure how China was able to actually conduct the test, it said.

Though the test happened in July, and was reported closer to the time, the nature of the breakthrough was first revealed in a new report from the Financial Times. The paper reported that experts have been poring through data in an attempt to understand how China was able to build the technology – as well as what exactly the missile was intended to do.

When it comes to carbon capture and storage, researchers have been getting creative by turning carbon dioxide into everything from carbon monoxide (CO) for the use in industrial processes to oxalic acid for processing rare earth elements. Now, it seems they are going back to its source, turning it into solid coal.

In a world-first breakthrough, a research team led by RMIT University in Melbourne, Australia developed a technique that can convert CO2 back into particles of carbon, decreasing pollution by removing greenhouse gases from our environment.

The solution offers a more viable approach than many of today’s carbon capture and storage systems that compress CO2 into a liquid form with the aim of injecting it underground. These approaches have many technical and safety issues and are also very costly.

The short-term effectiveness of a two-dose regimen of the BioNTech/Pfizer mRNA BNT162b2 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine was widely demonstrated. However, long term effectiveness is still unknown. Leveraging the centralized computerized database of Maccabi Healthcare Services (MHS), we assessed the correlation between time-from-vaccine and incidence of breakthrough infection between June 1 and July 27, the date of analysis. After controlling for potential confounders as age and comorbidities, we found a significant 1.51 fold (95% CI, 1.38−1.66) increased risk for infection for early vaccinees compared to those vaccinated later that was similar across all ages groups. The increased risk reached 2.26-fold (95% CI, 1.80−3.01) when comparing those who were vaccinated in January to those vaccinated in April. This preliminary finding of vaccine waning as a factor of time from vaccince should prompt further investigations into long-term protection against different strains.


The duration of effectiveness of SARS-CoV-2 vaccination is not yet known. Here, the authors present preliminary evidence of BNT162b2 vaccine waning across all age groups above 16, with a higher incidence of infection in people who received their second dose early in 2021 compared to later in the year.

What’s New: Today, Intel celebrates the 50th anniversary of the Intel® 4,004, the world’s first commercially available microprocessor. With its launch in November 1971, the 4,004 paved the path for modern microprocessor computing – the “brains” that make possible nearly every modern technology, from the cloud to the edge. Microprocessors enable the convergence of the technology superpowers – ubiquitous computing, pervasive connectivity, cloud-to-edge infrastructure and artificial intelligence – and create a pace of innovation that is moving faster today than ever.

“This year marks the 50th anniversary of the 4,004 chip. Think of how much we’ve accomplished in the past half-century. This is a sacred moment for technology. This is what made computing really take off!” –Pat Gelsinger, Intel CEO

Why It’s Important: The 4,004 is the pioneer microprocessor, and its success proved that it was possible to build complex integrated circuits and fit them on a chip the size of a fingernail. Its invention also established a new random logic design methodology, one that subsequent generations of microprocessors would be built upon, before evolving to create the chips found in today’s modern devices.

“If you want to measure something with very high precision, you almost always use an , because light makes for a very precise ruler,” says Jaime Cardenas, assistant professor of optics at the University of Rochester.

Now, the Cardenas Lab has created a way to make these optical workhorses even more useful and sensitive. Meiting Song, a Ph.D. student, has for the first time packaged an experimental way of amplifying interferometric signals—without a corresponding increase in extraneous, unwanted input, or “noise”—on a 1 mm by 1 mm integrated photonic . The breakthrough, described in Nature Communications, is based on a theory of weak value amplification with waveguides that was developed by Andrew Jordan, a professor of physics at Rochester, and students in his lab.
