Atomic 'Swiss Army knife' precisely measures materials for quantum computers
Running in Tarahumara culture
It images single atoms. It maps atomic-scale hills and valleys on metal and insulating surfaces. And it records the flow of current across atom-thin materials subject to giant magnetic fields. Scientists at the National Institute of Standards and Technology (NIST) have developed a novel instrument that can make three kinds of atom-scale measurements simultaneously. Together, these measurements can...

New high proton conductors with inherently oxygen deficient layers open sustainable future
Currently, low-alloy aluminum is widely used in electrical engineering and machine building. At the same time, it should be noted that modern electrical engineering places very high and in some cases mutually exclusive requirements to aluminum alloys.
Study shows great specificity of action by enzymes to correct double-strand DNA breaks
Over the past few years, fuel cells have become a focal point of research in eco-friendly technology because of their superior abilities to store and produce renewable energy and clean fuel. A typical type of fuel cell gaining ground is the proton-conducting fuel cell, which is primarily made of materials through which hydrogen ions (protons: H+), can easily move. Proton-conducting materials...
Researchers develop novel approach to modeling yet-unconfirmed rare nuclear process
Our cells are constantly dividing, and as they do, the DNA molecule—our genetic code—sometimes gets broken. DNA has twin strands, and a break in both is considered especially dangerous. This kind of double-strand break can lead to genome rearrangements that are hallmarks of cancer cells, said James Daley, Ph.D., of the Long School of Medicine at The University of Texas Health Science Center at...
Plant study challenges tropics' reputation as site of modern evolutionary innovation
Researchers from the Facility for Rare Isotope Beams (FRIB) Laboratory at Michigan State University (MSU) have taken a major step toward a theoretical first-principles description of neutrinoless double-beta decay. Observing this yet-unconfirmed rare nuclear process would have important implications for particle physics and cosmology. Theoretical simulations are essential to planning and...
Sorting and secreting insulin by expiration date
In a surprise twist, a major group of flowering plants is evolving twice as quickly in temperate zones as the tropics. The finding runs counter to a long-held hypothesis that tropical regions, home to the planet's richest biological diversity, outpace their temperate counterparts in producing new species.
Yellow pond-lily prefers cyclic flowers to spiral ones
A study in the Journal of Biological Chemistry describes a new way to determine the age of insulin-storage parcels, known as granules, and sheds light on how their age affects their release into the bloodstream. The findings could help experts better understand diabetes and fine-tune therapies for it.
COVID-19 shines spotlight on gender inequity in academia
Biologists from Lomonosov Moscow State University and HSE University have studied the patterns of flower development in yellow water-lily (Nuphar lutea). They found out that all the floral organs are arranged in cycles (whorls) rather than inserted sequentially in a spiral, as is the case in some other basal angiosperms. The ancestors of yellow pond-lily were among the first to diverge from the...
Researchers foresee linguistic issues during space travel
As COVID-19 spread across the country earlier this year, forcing schools and universities to close, Jessica L. Malisch began to notice an alarming trend—but not related to the virus.
Newly discovered pathogen in NY apples causes bitter rot disease
It lacks the drama of a shape-shifting alien creature, but another threat looms over the prospect of generations-long, interstellar space travel: Explorers arriving on Xanadu could face problems communicating with previous and subsequent arrivals, their spoken language having changed in isolation along the way.
Leap in lidar could improve safety, security of new technology
In a study of New York state apple orchards, Cornell plant pathologists have identified a new fungal pathogen that causes bitter rot disease in apples. Also, a second related fungus known to cause rot disease in other fruits was found for the first time in apples.
Study reveals secret life of lithium in Sun-like stars
Whether it's on top of a self-driving car or embedded inside the latest gadget, Light Detection and Ranging (lidar) systems will likely play an important role in our technological future, enabling vehicles to 'see' in real-time, phones to map three-dimensional images and enhancing augmented reality in video games.
Desert algae shed light on desiccation tolerance in green plants
Lithium is becoming common in our everyday lives. It is the key ingredient in the batteries of our mobile phones and electric vehicles, but have you ever wondered where it comes from?
Group genomics drive aggression in honey bees
Deserts of the U.S. Southwest are extreme habitats for most plants, but, remarkably, microscopic green algae live there that are extraordinarily tolerant of dehydration. These tiny green algae (many just a few microns in size) live embedded in microbiotic soil crusts, which are characteristic of arid areas and are formed by communities of bacteria, lichens, microalgae, fungi, and even small...
A tiny ancient relative of dinosaurs and pterosaurs discovered
Researchers often study the genomes of individual organisms to try to tease out the relationship between genes and behavior. A new study of Africanized honey bees reveals, however, that the genetic inheritance of individual bees has little influence on their propensity for aggression. Instead, the genomic traits of the hive as a whole are strongly associated with how fiercely its soldiers attack.
Behind the dead-water phenomenon
Dinosaurs and flying pterosaurs may be known for their remarkable size, but a newly described species from Madagascar that lived around 237 million years ago suggests that they originated from extremely small ancestors. The fossil reptile, named Kongonaphon kely, or "tiny bug slayer," would have stood just 10 centimeters (or about 4 inches) tall. The description and analysis of this fossil and its...
First direct evidence of ocean mixing across the Gulf Stream
What makes ships mysteriously slow down or even stop as they travel, even though their engines are working properly? This was first observed in 1893 and was described experimentally in 1904 without all the secrets of this 'dead water' being understood. An interdisciplinary team from the CNRS and the University of Poitiers has explained this phenomenon for the first time: the speed changes in ships...
Herpesvirsuses hedge their bets to optimize survival
New research provides the first direct evidence for the Gulf Stream blender effect, identifying a new mechanism of mixing water across the swift-moving current. The results have important implications for weather, climate and fisheries because ocean mixing plays a critical role in these processes. The Gulf Stream is one of the largest drivers of climate and biological productivity from Florida to...
Team obtained high-level control of spin qubit lifetime based on silicon quantum dots
When investors hedge a bet, they divvy their money between risky investments, which might make a large profit, and safe investments, which help ensure that not everything is lost in a market crash. The herpesvirus cytomegalovirus, Gladstone researchers have discovered, takes a similar approach to infecting the human body.
Owner behavior affects effort and accuracy in dogs' communications
By tuning the direction of the external magnetic field with respect to the crystallographic axis of the silicon wafer, an improvement of spin lifetime (relaxation time) by over two orders of magnitude was reported in silicon quantum dots. This breakthrough was carried out by a team led by academician Guo Guangcan from CAS Key Laboratory of Quantum Information, USTC, in which Prof. Guo Guoping,...
