Researchers apply the anti-de Sitter/conformal field theory to cosmology

The anti-de Sitter/conformal field theory (AdS/CFT) correspondence, also referred to as gauge/gravity duality, hypothesizes the existence of a relationship between two types of physics theories, namely gravity theories in AdS spacetimes and CFTs. Over the past few decades, gauge/gravity duality constructs have been applied in a wide range of scientific research fields. For instance, some researchers tried to use AdS/CFT to advance the development of a full quantum theory of gravity.

The spin state story: Observation of the quantum spin liquid state in novel material

Aside from the deep understanding of the natural world that quantum physics theory offers, scientists worldwide are striving to bring forth a technological revolution by leveraging this newfound knowledge in engineering applications. Spintronics is an emerging field that aims to surpass the limits of traditional electronics by using the spin of electrons, which can be roughly seen as their angular rotation, as a means to transmit information.

Novel 'dual-resonant method' in 2-D materials can spur advances in the field of photonics

Scientists at Daegu Gyeongbuk Institute of Science and Technology, Korea, have developed a new process that provides an ultrafast process of photon generation in two-dimensional materials. This process can potentially fuel the development of advanced optical devices in the field of photonics.

Calculating the true pressure required to propel penguin feces

A pair of researchers, one with Kochi University, the other Katsurahama Aquarium, both in Japan, has refined the estimate of the amount of pressure required by an Adélie penguin to shoot its feces a necessary distance. Hiroyuki Tajima and Fumiya Fujisawa have written a paper describing their new calculations and what it could mean for zookeepers.

T-ray camera speed boosted a hundred times over

Scientists are a step closer to developing a fast and cost effective camera that utilises terahertz radiation, potentially opening the opportunity for them to be used in non-invasive security and medical screening.

Scientists dive deep into hidden world of quantum states

A research team led by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a technique that could lead to new electronic materials that surpass the limitations imposed by Moore's Law, which predicted in 1975 that the number of transistors packed into a tiny silicon-based computer chip would double every two years. Their findings were reported in the journal Nature Communications.

Cosmic cataclysm allows precise test of general relativity

In 2019, the MAGIC telescopes detected the first Gamma Ray Burst at very high energies. This was the most intense gamma-radiation ever obtained from such a cosmic object. But the GRB data have more to offer: with further analyses, the MAGIC scientists could now confirm that the speed of light is constant in vacuum—and not dependent on energy. So, like many other tests, GRB data also corroborate Einstein's theory of General Relativity. The study has now been published in Physical Review Letters.

Cherned up to the maximum

In topological materials, electrons can display behavior that is fundamentally differentfrom that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional to an entity known as the Chern number. New experiments establish for the first time that the theoretically predicted maximum Chern number can be reached—and controlled—in a real material.

The darkness at the end of the tunnel

The Cage, as the elevator is called, leaves at exactly 7:30 a.m. Latecomers are out of luck.

CERN: physicists report the discovery of unique new particle

The LHCb collaboration at CERN has announced the discovery of a new exotic particle: a so-called "tetraquark". The paper by more than 800 authors is yet to be evaluated by other scientists in a process called "peer review", but has been presented at a seminar. It also meets the usual statistical threshold for claiming the discovery of a new particle.

Radio-over-fiber compression poised to advance 5G wireless networks

Although new 5G networks can offer much faster and more efficient wireless data transfer, the fiber optic networks currently used to connect wireless devices to the internet cannot easily support the increased load. A new study shows that a compression scheme for radio-over-fiber links could help solve this problem for a variety of 5G formats.

CERN: The first accelerators are back in action

The CERN Control Centre is back in shift work mode, with walls of screens showing the status of the beams, and coffee flowing freely day and night. On Friday, 3 July, the Long Shutdown 2 accelerator coordination team handed over the key of the PS Booster to the accelerator operators. Linac 4 and the PS Booster thus become the first two accelerators to be recommissioned, 18 months after the start of LS2.

Astronomy and Space news

VERITAS: exploring the deep truths of Venus

Imagine Earth. Now fill the skies with thick, sun-obscuring clouds of sulfuric acid; boil off the oceans by cranking up the temperature to 900 degrees Fahrenheit (nearly 500 degrees Celsius), and boost the air pressure high enough to flatten you like a pancake. What you now have is Venus, a rocky planet similar in size to Earth but different in almost every other way.

Making the case for slingshotting past Venus on the way to Mars

A team of researchers from the Johns Hopkins University Applied Physics Laboratory, North Carolina State University and NASA, has proposed, via whitepaper, that NASA should direct its Mars-bound spacecraft to fly by Venus first. In their paper, uploaded to the arXiv preprint server, the researchers outline their arguments for an opposition mission, as opposed to a conjunction mission.

Supermassive binary black hole hunter: SKA pulsar timing array

Recently, researchers from the National Astronomical Observatory of the Chinese Academy of Sciences quantified the potential of gravitational wave detection in the era of the Square Kilometer Array (SKA). The study was published in Physical Review D.

Of course, every technology has its abusers and our always-connected smartphones, tablets, and laptops are no different.

What if cell service were portable?

When Hurricane Maria, a deadly category 5 hurricane, hit Puerto Rico in September 2017, it caused catastrophic destruction that cost billions of dollars and thousands of lives.

Why stakeholders in the 'wind energy vs. biological conservation' conflict have low mutual trust

Wind energy is considered to be one of the most promising forms of renewable energy. Yet, each year, wind turbines are responsible for the death of hundreds of thousands of airborne animals such as bats which die from collisions with turbine blades. To find a constructive way out of this "green-green" dilemma, companies building and running wind turbines might have to work together with environmental experts and conservationists. Yet a lack of trust between them is likely to hinder effective and creative collaboration.
