British startup Urban-Air Port (UAP) has announced plans to open 200 flying taxi and cargo drone hubs in 65 cities globally over the next five years. The announcement comes following a significant investment from Supernal, a division of Hyundai Motor Group, to deliver on the company’s shared vision of integrating advanced air mobility (AAM) into existing transit networks and creating a seamless passenger journey.

UAP’s vertiport sites will provide essential infrastructure to help enable mass adoption of eVTOL aircraft – such as cargo drones and air taxis – as public acceptance grows and will transform the way goods and people are transported around urban areas. The world’s first fully operational hub for eVTOLs, Air-One, will open for public visitation in Coventry City Centre in April.

The demonstration will show how AAM can help unlock the potential of sustainable mobility and how the industry will work to help reduce congestion, cut air pollution and decarbonize transport.

China set a ground-breaking record with its “artificial sun,” which superheated plasma to temperatures five times hotter than the sun. The Experimental Advanced Superconducting Tokamak (EAST) nuclear fusion reactor reached 158 million degrees Fahrenheit for 1,056 seconds (17 minutes, 36 seconds). This latest breakthrough brings the country one step closer toward its goal for unlimited clean fusion energy.

China’s EAST surpassed France’s Tore Supra tokamak record, set in 2003 when it superheated plasma in its coiling loop to identical temperatures for 390 seconds. Also, in May 2021, EAST set another record by running at 216 million F for 101 seconds. The fusion reactor achieved a peak temperature of 288 million Fahrenheit for 20 seconds during this experiment. In comparison, the sun’s core reaches approximately 27 million Fahrenheit.

Giving low-income families more money changes a child’s brain activity, and the effect can be seen by a child’s first birthday.

“Neuroscientists have described links between a child’s socioeconomic background and the structure of the brain,” says Kimberly Noble at Columbia University in New York. “But all that work has been correlational to date.”

Instead, Noble and her team are looking at how exactly child poverty causes reduced grey matter volume in the hippocampus and frontal cortex, which is associated with the subsequent development of thinking and learning. These changes have been seen throughout childhood and adolescence.

The discovery, one of the only confirmed intermediate-mass black holes, lives in an equally rare object known as a low-mass, stripped nucleus.

Astronomers discovered a black hole unlike any other. At one hundred thousand solar masses, it is smaller than the black holes we have found at the centers of galaxies, but bigger than the black holes that are born when stars explode. This makes it one of the only confirmed intermediate-mass black holes, an object that has long been sought by astronomers.

“We have very good detections of the biggest, stellar-mass black holes up to 100 times the size of our sun, and supermassive black holes at the centers of galaxies that are millions of times the size of our sun, but there aren’t any measurements of black between these. That’s a large gap,” said senior author Anil Seth, associate professor of astronomy at the University of Utah and co-author of the study. “This discovery fills the gap.”

The first molecular electronics chip has been developed, realizing a 50-year-old goal of integrating single molecules into circuits to achieve the ultimate scaling limits of Moore’s Law. Developed by Roswell Biotechnologies and a multi-disciplinary team of leading academic scientists, the chip uses single molecules as universal sensor elements in a circuit to create a programmable biosensor with real-time, single-molecule sensitivity and unlimited scalability in sensor pixel density. This innovation, appearing this week in a peer-reviewed article in the Proceedings of the National Academy of Sciences (PNAS), will power advances in diverse fields that are fundamentally based on observing molecular interactions, including drug discovery, diagnostics, DNA sequencing, and proteomics.

“Biology works by talking to each other, but our existing measurement methods cannot detect this,” said co-author Jim Tour, Ph.D., a Rice University chemistry professor and a pioneer in the field of molecular electronics. “The demonstrated in this paper for the first time let us listen in on these molecular communications, enabling a new and powerful view of biological information.”

The molecular electronics platform consists of a programmable semiconductor chip with a scalable sensor array architecture. Each array element consists of an electrical current meter that monitors the current flowing through a precision-engineered molecular wire, assembled to span nanoelectrodes that couple it directly into the circuit. The sensor is programmed by attaching the desired probe molecule to the molecular wire, via a central, engineered conjugation site. The observed current provides a direct, electronic readout of molecular interactions of the probe. These picoamp-scale current-versus-time measurements are read out from the sensor array in digital form, at a rate of 1,000 frames per second, to capture molecular interactions data with high resolution, precision and throughput.

By using quantum key distribution (QKD), quantum cryptographers can share information via theoretic secure keys between remote peers through physics-based protocols. The laws of quantum physics dictate that photons carrying signals cannot be amplified or relayed through classical optical methods to maintain quantum security. The resulting transmission loss of the channel can limit its achievable distance to form a huge barrier to build large-scale quantum secure networks. In a new report now published in Nature Photonics, Shuang Wang and a research team in quantum information, cryptology and quantum physics in China developed an experimental QKD system to tolerate a channel loss beyond 140 dB across a secure distance of 833.8 km to set a new record for fiber-based quantum key distribution. Using the optimized four-phase twin-field protocol and high quality setup, they achieved secure key rates that were more than two orders of magnitude greater than previous records across similar distances. The results form a breakthrough to build reliable and terrestrial quantum networks across a scale of 1,000 km.

Quantum cryptography and twin-field quantum key distribution (QKD)

Quantum key distribution is based on fundamental laws of physics to distribute secret bits for information-theoretic secure communication, regardless of the unlimited computational power of a potential eavesdropper. The process has attracted widespread attention in the past three decades relative to the development of a global quantum internet, and matured to real-world deployment through optical-fiber networks. Despite this, wider applications of QKD are limited due to channel loss, limiting increase in the key rate and range of QKD. For example, photons are carriers of quantum keys in a QKD setup, and they can be prepared at the single-photon level to be scattered and absorbed by the transmission channel. The photons, however, cannot be amplified, and therefore the receiver can only detect them with very low probability. When transmitted via a direct fiber-based link from the transmitter to the receiver, the key rate can therefore decrease with transmission distance.
