Physicists engineer an optical mirror made of only a few hundred atoms

Physicists at the Max Planck Institute of Quantum Optics (MPQ) have engineered the lightest optical mirror imaginable. The novel metamaterial is made of a single structured layer that consists only of a few hundred identical atoms. The atoms are arranged in the two dimensional array of an optical lattice formed by interfering laser beams. The research results are the first experimental observations of their kind in an only recently emerging new field of subwavelength quantum optics with ordered atoms. So far, the mirror is the only one of its kind. The results are today published in Nature.

Researchers observe new, very short-lived neptunium isotope

In a recent study, researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences and their collaborators reported the first discovery of 222Np, a new very short-lived neptunium (Np) isotope, and validated the N = 126 shell effect in Np isotopes.

Streamlining quantum information transmission

The quantum realm holds the key to the next revolution in communication technology as we know it. With the promise of unprecedented performance and impenetrable security, quantum technology is taking its first steps towards the ultimate goal of applications such as highly encrypted yet nearly fast-as-light financial transactions. However, the ability for quantum computers to communicate with one another has been limited by the resources required for such exchanges, constraining the amount of information that can be traded, as well as the amount of time it can be stored.

Regular arrays of silicon nanoparticles key to improving light emissions in nanophotonic devices

Nanophotonics considers how light and matter at the nanoscale interact with each other, with findings in the field being important for nanofabrication techniques and in future photonic devices.

New transient X-ray source detected in the galaxy NGC 4945

Using the Suzaku satellite, Japanese astronomers have detected a transient X-ray source in a nearby galaxy known as NGC 4945. The newly discovered source, designated Suzaku J1305−4930, appears to be a black hole binary. The finding is detailed in a paper published July 8 on the arXiv pre-print repository.

Solar Orbiter gives scientists unprecedented look at Sun

Scientists said Thursday they had obtained the closest ever images taken of the Sun as part of a pan-European mission to study solar winds and flares that could have far-reaching impacts back on Earth.

Close-ups of the sun

Only a few months after its launch, ESA's Solar Orbiter has captured images of the sun from a previously unattainable distance. Among other things, these images reveal structures in the sun's atmosphere that could possibly be interpreted as so-called nanoflares, very small bursts of radiation. The images from the six remote sensing instruments published today were taken in the days before and after 15 June, when the spacecraft reached the point closest to the sun on its current orbit. Only 77 million kilometres separated the probe from our star. Although this early mission phase is primarily aimed at commissioning the instruments, the data already provide impressive evidence of Solar Orbiter's uniquely comprehensive view of the sun—from the magnetic fields at the surface to the particles streaming into space. The Max Planck Institute for Solar System Research (MPS) in Germany is an important partner of the mission and is significantly involved in four of the instruments.

How galaxies die: New insights into the quenching of star formation

Astronomers studying galaxy evolution have long struggled to understand what causes star formation to shut down in massive galaxies. Although many theories have been proposed to explain this process, known as "quenching," there is still no consensus on a satisfactory model.

In a first, astronomers watch a black hole's corona disappear, then reappear

New research of oldest light confirms age of the universe

Just how old is the universe? Astrophysicists have been debating this question for decades. In recent years, new scientific measurements have suggested the universe may be hundreds of millions of years younger than its previously estimated age of approximately 13.8 billions of years. Now new research published in a series of papers by an international team of astrophysicists, including Neelima Sehgal, Ph.D., from Stony Brook University, suggest the universe is about 13.8 billion years old. By using observations from the Atacama Cosmology Telescope (ACT) in Chile, their findings match the measurements of the Planck satellite data of the same ancient light.

New insights into the origins of our universe

New data released today by the Atacama Cosmology Telescope (ACT) in Chile indicate our universe is around 13.8 billion years old, matching the measurements made by the Planck satellite in 2015, and calling into question the 2019 findings of another research group that determined the age of the universe to be much younger than what the Planck satellite had predicted. That study had measured the movement of galaxies to come up with their number, while the ACT measured polarized light to reach its conclusions.

Recognising fake images using frequency analysis

They look deceptively real, but they are made by computers: so-called deep-fake images are generated by machine learning algorithms, and humans are pretty much unable to distinguish them from real photos. Researchers at the Horst Görtz Institute for IT Security at Ruhr-Universität Bochum and the Cluster of Excellence "Cyber Security in the Age of Large-Scale Adversaries" (Casa) have developed a new method for efficiently identifying deep-fake images. To this end, they analyse the objects in the frequency domain, an established signal processing technique.

Taxis drive smart city creation

As the world has advanced technologically, the word "smart" has been applied to everything from smartphones to smart homes. Everything is "smart" now, including cities. A smart city utilizes various Internet of Things (IoT) sensors to collect data around the city, which is analyzed to better run and manage the city's resources and services. Some applications include traffic congestion, noise, and pollution control, among others.

Engineer creates a battery-less remote image sensor, and teaches it time management

Imagine a small, inexpensive device that could look at a parking lot to see which spaces are filled and which are not. Or one that could find traffic jams and reroute others away from it. Maybe such a device could even keep an eye out for dangerous situations in public places. Brandon Lucia, assistant professor of electrical and computer engineering at Carnegie Mellon University, along with his Ph.D. student Harsh Desai and collaborators from the University of Trento in Italy, imagined a device like this, and they named it Camaroptera, after a tiny, industrious bird.
