A quantum machine can drastically speed up certain kinds of computation, but only if two or more quantum bits in the machine are entangled—that is, capable of displaying related behavior despite being separated.

Advancing Canada Water Assets (ACWA), a joint initiative between the City of Calgary and the University of Calgary, is applying the same techniques it used to monitor COVID-19 case numbers to track illicit drugs in the province's...

Palm oil is the world's most produced and consumed vegetable oil and everyone knows that its production can damage the environment. But do consumers have the full picture? In fact, replacing palm oil with rapeseed oil would require a four to five-fold increase in the amount of land needed.

Maintaining a water level between 20 and 30 centimeters below the local water table will boost southern peatlands' carbon storage and reduce the amount of climate-warming carbon dioxide (CO2) and methane they release back into the atmosphere during dry periods by up to 90%, a new Duke University study finds.

Understanding how voltage drives nanoscale electrocatalysts to initiate reactions is a fundamental scientific question. This is especially challenging when dealing with non-metallic electrocatalysts due to their low inherent carrier concentration, which leads to poor conductivity. When voltage is applied at the non-metal/solution interface, the situation becomes more complex than in the case of...

German Executives are most concerned about the impact of hot weather and heavy rains on their companies' operations. Apart from this, however, they also have an awareness of the consequences of climate change on their value chains. This is revealed by the current IfM survey of more than 1,300 managing executives on the current Climate Adaptation Week of the Federal Ministry for the Environment.

As energy demand continues to rise, research into new, efficient renewable and clean energy sources is an urgent priority. Currently, renewable energy sources like solar, wind, tide, and geothermal make up less than 40% of the current energy demand. Increasing this percentage and reducing the amount of fossil fuels used will require other, more efficient renewable and clean energy sources.

A new study combined expertise in barley genetics and genomics from the research group led by Dr. Ping Yang (Institute of Crop Sciences, Chinese Academy of Agricultural Sciences) and that in barley microspore culturing led by Dr. Chenghong Liu (Biotech Research Institute, Shanghai Academy of Agricultural Sciences), in order to address the time- and space-cost issue in developing homozygous induced...

The drive to explore deeper into space and establish colonies on other planets has intensified over the last decade, and with it the importance of space resources extraction.

Urban sprawl and insufficient relief measures have left an Ottawa-area freshwater turtle facing extinction within the decade, says new research from the University of Ottawa and Trent University, which tracked changes to the turtle's habitat over a 10-year period.

If you think there were more mosquitoes this year than usual, you're not wrong.

Airlines have long competed to enhance their on-time performance, and new research from the University at Buffalo School of Management reveals the most effective strategies for improving rankings in this key indicator of punctuality and service reliability.

The melting of the supergiant iceberg A-68 had a huge impact on the ocean around South Georgia, in sub-Antarctica, and significantly changed the Southern Ocean's temperature and saltiness, with potentially major consequences for this ecologically significant region. These results are published this week in the journal Geophysical Research Letters.

An extraordinary heat wave is assailing the world's oceans with an intensity that is surprising climate researchers. Environmental physicist Nicolas Gruber provides some context.

Humans are arguably the most adaptable species on Earth. The species' enormous capacity to adapt and live in different environments is thanks to cumulative culture, the transmission and continuous improvement of knowledge and technologies between individuals and generations.

A recent study submitted to Acta Astronautica and currently available on the arXiv preprint server explores the potential for using aerographite solar sails for traveling to Mars and interstellar space, which could dramatically reduce both the time and fuel required for such missions.

During a research expedition led by Linnaeus University and Stockholm University to the deepest parts of the Baltic Sea in the Landsort Deep researchers recently discovered an area with extensive emissions of the powerful greenhouse gas methane from the bottom sediments.

What chemicals are we exposed to on a daily basis? That is the central question of "non-targeted analysis" or NTA, an emerging field of analytical science that aims to identify all chemicals around us. A daunting task, because how can you be sure to detect everything if you don't know exactly what you're looking for?

The Chinese Academy of Sciences Earth System Model (CAS-ESM2.0), a sophisticated Earth modeling tool, has achieved a major breakthrough in fully coupled atmospheric CO2 simulation, as revealed in Advances in Atmospheric Sciences.

Clothes that are produced quickly and just as quickly go out of style and into the trash bin can have dire effects on the environment, polluting the air with carbon and choking landfills with chemicals that can seep into the water supply.

An international study by tourism and hospitality experts in the U.S. and China has determined the "staycation phenomenon," which reached prominence during the COVID-19 pandemic, is still going strong and is most likely here to stay as part of a new industry normal.

If you take a universe worth of hydrogen and helium, and let it stew for about 13 billion years, you get us. We are the descendants of the primeval elements. We are the cast-off dust of the first stars, and many generations of stars after that. So our search for the first stars of the cosmos is a search for our own history. While we haven't captured the light of those first stars, some of their...
