NASA's Lucy spacecraft poised to launch Oct. 16
NASA's Lucy spacecraft is encapsulated in a protective fairing atop an Atlas V rocket, awaiting its 23-day launch window to open on October 16. All is go for the Southwest Research Institute-led mission to begin, as the spacecraft prepares to launch on a 12-year journey of almost 4 billion miles to visit a record-breaking eight asteroids—one main belt asteroid and seven Jupiter Trojan asteroids.

Wildfires affect cave diversity underneath scorched surfaces
The landscape at Lava Beds National Monument in northern California is typically home to sage and junipers, with unique lava caves twisting underneath the surface. But in the summers of 2020 and 2021, wildfires tore through the region, burning thousands of acres and leaving the surface charred.

Challenging the big bang puzzle of heavy elements
It has long been theorized that hydrogen, helium, and lithium were the only chemical elements in existence during the Big Bang when the universe formed, and that supernova explosions, stars exploding at the end of their lifetime, are responsible for transmuting these elements into heavier ones and distributing them throughout our universe.

No apparent shortage of prey for southern resident killer whales in Canadian waters during summer
A popular belief that there are fewer Chinook salmon during the summer in Canadian waters for southern resident killer whales, compared to an abundance of fish for northern resident killer whales, has been debunked by a study led by scientists at the University of British Columbia.
Tucked-away marble quarries discovered as source for archaic Apollo
The source of marble for a statue of Apollo on the Greek island of Delos has been a mystery to art historians and archaeologists for decades. The stone's chemistry pointed geochemists to the southern end of the nearby island of Naxos, but no one thought there were ancient marble quarries there. A geoarchaeologist believes he found the source.
Global ISA dynamics observed by Landsat satellites from 1972 to 2019
For half a century, human activities drastically altered the climate, environment, and ecosystem of the Earth, which restricted the sustainable development and affected human well-being. Impervious surface areas (ISA), i.e., artificial structures with impermeable characteristics, mainly including roofs, paved surfaces, roads, and hardened grounds, are the most affected regions. Using more than three million Landsat satellite images, this research developed the first global impervious surface area (GISA) dataset from 1972 to 2019. Based on 120,777 independent and random reference sites from 270 cities all over the world, the omission error, commission error, and F-score of GISA are 5.16%, 0.82%, and 0.954, respectively.
Researchers achieve universal route to family of penta-twinned gold nanocrystals
A research team led by Prof. Li Yue from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences (CAS), together with Prof. Li Cuncheng from University of Jinan, has recently developed a universal route with fine kinetic control to a family of penta-twinned gold nanocrystals.
Desert locusts remain a serious threat to Pakistan
In 2019 and 2020, desert locusts once again plagued parts of East Africa and huge areas as far as India and Pakistan through the Arabian Peninsula, in an infestation that was described as the worst in decades. A serious agricultural pest, the desert locust Schistocerca gregaria can feed on most types of crops, including grains, vegetables and fruit, causing significant damage to agricultural production and threatening food security in many countries.

New research directions in disordered carbon anodes for Na-ion batteries
Na-ion batteries (NIBs) are gradually attracting much attention as an alternative to lead-acid batteries and supplement to Li-ion batteries (LIBs) owing to the abundant Na resources and excellent cost-effectiveness. Since the most commonly used graphite as an anode material in LIBs cannot be inherently used in NIBs, tremendous efforts have been made to advance the fundamental understanding and design of suitable anode materials for NIBs, including the improvement of Na storage capacity and the study on Na storage mechanisms. According to all these studies, disordered carbons are now the most promising anode candidates for NIBs. Nevertheless, there are still many challenges need to be addressed, and the further exploration of disordered carbon anodes is very important in the future.

Discovery of universal adversarial attacks for quantum classifiers
Artificial intelligence has achieved dramatic success over the past decade, with the triumph in predicting protein structures marked as the latest milestone. At the same time, quantum computing has also made remarkable progress in recent years. A recent breakthrough in this field is the experimental demonstration of quantum supremacy. The fusion of artificial intelligence and quantum physics gives rise to a new interdisciplinary field—-quantum artificial intelligence.

'Caramel receptor' identified
Who doesn't like the smell of caramel? However, the olfactory receptor that contributes decisively to this sensory impression was unknown until now. Researchers at the Leibniz Institute for Food Systems Biology at the Technical University of Munich (LSB) have now solved the mystery of its existence and identified the "caramel receptor". The new knowledge contributes to a better understanding of the molecular coding of food flavors.
Destructive insects produce high-value products from biowaste
European researchers and industries are putting insects to work—from termites that destroy wooden buildings to insect larvae that are star "poop" composters. Packaging, cosmetics, pharmaceuticals and animal feed are just some of the products they are beetling away to make for us.

Researchers realize quantum teleportation onto mechanical motion of silicon beams
Quantum technology typically employs qubits (quantum bits) consisting of, for example, single electrons, photons or atoms. A group of TU Delft researchers has now demonstrated the ability to teleport an arbitrary qubit state from a single photon onto an optomechanical device—consisting of a mechanical structure comprising billions of atoms. Their breakthrough research, now published in Nature Photonics, enables real-world applications such as quantum internet repeater nodes while also allowing quantum mechanics itself to be studied in new ways.
