A vast majority of Canadians reported being at least as productive working from home, and many prefer not to return to the office after pandemic restrictions are lifted, according to a study released Thursday.

The severity of crop losses driven by heat waves and drought have tripled in the last fifty years in Europe, according to a study that highlights the vulnerability of food systems to climate change.

On the afternoon of April 13, 2018, a large wave of water surged across Lake Michigan and flooded the shores of the picturesque beach town of Ludington, Michigan, damaging homes and boat docks, and flooding intake pipes. Thanks to a local citizen's photos and other data, NOAA scientists reconstructed the event in models and determined this was the first ever documented meteotsunami in the Great...

For the first time, researchers have discovered a way to obtain polarity and photovoltaic behavior from certain nonphotovoltaic, atomically flat (2D) materials. The key lies in the special way in which the materials are arranged. The resulting effect is different from, and potentially superior to, the photovoltaic effect commonly found in solar cells.

A group of scientists from the University of Koblenz-Landau, Germany, has shown that for plants and insects, pesticide toxicity in agriculture has substantially increased between 2004 and 2016. In a paper published in the current issue of Science, the authors show that this pattern is even relevant in genetically modified (GM) crops that were originally designed to reduce pesticide impacts on the...

About 10 years ago, researchers at the University of Bonn produced an extreme aggregate photon state, a single "super-photon" made up of many thousands of individual light particles, and presented a completely new light source. The state is called an optical Bose-Einstein condensate and has captivated many physicists ever since, because this exotic world of light particles is home to its very own...

Tropical rainforests today are biodiversity hotspots and play an important role in the world's climate systems. A new study published today in Science sheds light on the origins of modern rainforests and may help scientists understand how rainforests will respond to a rapidly changing climate in the future.

We know your cat's whiskers are handsome—but you can't even see the cool part.

A new, detailed model of the surface of the SARS-CoV-2 spike protein reveals previously unknown vulnerabilities that could inform development of vaccines. Mateusz Sikora of the Max Planck Institute of Biophysics in Frankfurt, Germany, and colleagues present these findings in the open-access journal PLOS Computational Biology.

Six genetic variants add up to determine the risk of several blood cancers in pre-disposed dog breeds, according to a study by Benoît Hédan at the University of Rennes and colleagues, publishing April 8th in the open-access journal PLOS Genetics. The results confirm a known tumour-suppressor gene as a risk factor for histiocytic sarcoma—a rare and aggressive blood cancer that affects both dogs...

Despite the fact that our planet is mostly ocean and human maritime activity is more intense than it has ever been, we know remarkably little about the state of the ocean's biodiversity—the variety and balance of species that support healthy and productive ecosystems. And it's no surprise—marine biodiversity is complex, human impacts are uneven, and species respond differently to different...

Plant inducible defense starts with the recognition of microbes, which leads to the activation of a complex set of cellular responses. There are many ways to recognize a microbe, and recognition of microbial features by pattern recognition receptors (PRRs) outside the cell was long thought to activate the first line of defense: Pattern Triggered Immunity, or PTI. To avoid these defense responses,...

NASA's OSIRIS-REx mission is on the brink of discovering the extent of the mess it made on asteroid Bennu's surface during last fall's sample collection event. On Apr. 7, the OSIRIS-REx spacecraft will get one last close encounter with Bennu as it performs a final flyover to capture images of the asteroid's surface. While performing the flyover, the spacecraft will observe Bennu from a distance of...

NASA's InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae—the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes of 3.3 and 3.1; the previous quakes were magnitude 3.6 and 3.5. InSight has recorded over 500 quakes to date, but because of their clear signals, these are four of the best...

Europa Clipper, NASA's upcoming flagship mission to the outer solar system, has passed a significant milestone, completing its Critical Design Review. During the review, experts examined the detailed design of the spacecraft to ensure that it is ready to complete construction. The mission is now able to complete hardware fabrication and testing, and move toward the assembly and testing of the...

Recent research from the University of Vaasa and the University of Jyväskyla shows that speculation and lottery-like behavior is a fundamental factor for the pricing of cryptocurrencies. Speculation could explain the enormous increase in the market capitalizations of cryptocurrencies.

Space scientists at the University of Bath in the UK have found a new way to probe the internal structure of neutron stars, giving nuclear physicists a novel tool for studying the structures that make up matter at an atomic level.

Many slopes in the Campania region of Italy are covered with layers of volcanic soil, the result of repeated eruptions over the course of millennia. As the impacts of climate change worsen, including the occurrence of very intense and short rainfall in localized areas, there is a growing need, especially in this and other Italian regions that are vulnerable to landslides, to understand the...

Grain boundaries (GBs) in PSCs have been found to be detrimental to the photovoltaic performance of the devices. Numerous papers reported that the defects in perovskite GBs should be passivated by suitable materials, such as quaternary ammonium halide, fullerene derivatives and CH3NH3I, to alleviate carrier recombination and consequently improve the device performance.

A team led by Professor Du Jiangfeng and Professor Wang Ya from the Chinese Academy of Sciences (CAS) Key Laboratory of Microscale Magnetic Resonance of the University of Science and Technology of China put forward an innovative spin-to-charge conversion method to achieve high-fidelity readout of qubits, stepping closer towards fault-tolerant quantum computing.

Although beef is one of the most consumed foods around the world, eating it when it's past its prime is not only unsavory, but also poses some serious health risks. Unfortunately, available methods to check for beef freshness have various disadvantages that keep them from being useful to the public. For example, chemical analysis or microbial population evaluations take too much time and require...

Many wildlife species are threatened by shrinking habitat. But according to new research, the potential range of African elephants could be more than five times larger than its current extent.

A new study shows that the similarly smooth, nearly hairless skin of whales and hippopotamuses evolved independently. The work suggests that their last common ancestor was likely a land-dwelling mammal, uprooting current thinking that the skin came fine-tuned for life in the water from a shared amphibious ancestor. The study is published today in the journal Current Biology and was led by...

The University of Maryland (UMD) has collaborated with Cornell University and Stanford University to quantify the man-made effects of climate change on global agricultural productivity growth for the first time. In a new study published in Nature Climate Change, researchers developed a robust model of weather effects on productivity, looking at productivity in both the presence and absence of...
