Climate change is subjecting plants to rapid shifts in temperature and precipitation, pushing them into new ranges and stressing them in old ones.
In an era marked by an escalating energy crisis, the world stands on the precipice of a transformative revolution in spintronics technology, promising ultra-low power consumption paired with superior performance. To illustrate the potential, consider this: the power consumed by AlphaGo during its famous Go game in 2016 equaled the daily power use of 100 households. By 2021, Tesla's autonomous...

A new study published in OMICS: A Journal of Integrative Biology has identified genes for virulence and antimicrobial resistance in two bacteria that co-occur with C. difficile, suggesting these pathogens as emerging potential threats in planetary health.
Solid oxide electrolysis cells (SOECs) provide a practical solution for direct conversion of CO2 to chemicals; however, an in-depth mechanistic understanding of the dynamic reconstruction of active sites for perovskite cathodes during CO2 electrolysis remains a great challenge.
New research from Copenhagen Business School, along with Leuphana University and University of Turku sheds light on the importance of subtracting as much as adding in the journey of digital workplace transformation.
Virgin Galactic completed what's expected to be its final test flight Thursday before taking paying customers on brief trips to space, marking what the space tourism company described as a "fantastic...
What is the impact of affirmative actions, such as quota systems, on minorities' representation in top ranks of the academic and corporate worlds? Scientists used mathematical models for the first time to quantify how successful quota systems can be for improving women's visibility in science.
On a sunny springtime stroll through a park, it's easy to ignore the parts of plants that are hidden from view. Plant biologists see things differently. They look below the surface where plant roots are organized in elaborate systems that are critical to the organism's development. Intricately organized tree root systems, for example, can span as far underground as the tree grows high above the...
In two new studies, North Carolina State University researchers have designed and tested a series of textile fibers that can change shape and generate force like a muscle. In the first study, published in Actuators, the researchers focused on the materials' influence on artificial muscles' strength and contraction length. The findings could help researchers tailor the fibers for different...
The Delaware River could rise well more than a foot by midcentury, and temperatures could heat up nearly 6 degrees, accompanied by a rise in extreme heat days, according to a new report that localized data to create a snapshot of local climate change in Philadelphia.
When a new role opens up at a company, managers often face a choice: Promote an employee from within or bring an external candidate on board.
After months of using weed-killers, saws, shovels and hand-yanking invasive latherleaf fern out of a tropical forest on Virginia Key Beach Park, City of Miami parks naturalist Gloria Alejandra Antia was finally able to begin the process of rebuilding.
This winter's major storms laid down one of the largest snowpacks recorded in California's Sierra Nevada, along with an unusual amount of snow at low mountain elevations.
As part of the study titled "The impact of commission bans on household wealth: Findings from OECD countries," a team led by Professor Steffen Sebastian, Director at the Center for Finance at the University of Regensburg, investigated the impact of commission bans on the brokerage of financial investments.
Scientists in Finland have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures—a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.
Satellites are helping Europe protect its lakes, lagoons and rivers.
A research team at the University of Cordoba has identified, for the first time, the composition of a Roman perfume more than 2,000 years old thanks to the discovery of a small vessel of ointment in Carmona.
Earth's magnetic field, generated by the flow of molten iron in the planet's inner core, extends out into space and protects us from cosmic radiation emitted by the sun. It is also remarkably used by animals like salmon, sea turtles and migratory birds for navigation.
Researchers have developed a quantum key distribution (QKD) system based on integrated photonics that can transmit secure keys at unprecedented speeds. The proof-of-principle experiments represent an important step toward real-world application of this highly secure communication method.
Before their approval, pharmaceuticals not only have to be tested for their effectiveness and safety, but also for their stability, since they are usually stored in pharmacies and private households for years. To test stability, a process is needed that decomposes a drug "in fast motion."
AI used to discover abaucin, an effective drug against A baumannii, bacteria that can cause dangerous infectionsScientists using artificial intelligence have discovered a new antibiotic that can kill a deadly superbug.According to a new study published on Thursday in the science journal Nature Chemical Biology, a group of scientists from McMaster University and the Massachusetts Institute of...
The dog, man's best friend, is a popular pet. There are hundreds of different dog breeds, each of which is said to have a personality of their own. A study recently completed at the University of Helsinki confirms this notion of personality differences between dog breeds. The research is published in the journal iScience.
Can isolated black holes account for dark matter? Rick PinsonLong Beach, California Astronomers estimate about 100 million black holes wander the Milky Way. Since black holes emit no light, we rely on indirect methods to infer their presence. The first method is to search for a black hole’s gravitational influence on nearby objects, such asContinue reading "Ask Astro: Could isolated black holes...
Today's outdoor clothing mainly relies on oil-based fibers and chemicals that are harmful for the environment. In her doctoral research, Helena Sederholm develops environmentally friendly water-repellent textiles by following the example of nature.
Recently, the journal Science China Earth Sciences published a study led by Dr. Wang Huan (Sichuan Normal University) and Professor Zuo Zhiyan (Fudan University). Based on modern observations, historical proxy data, and climate model simulations, this study provides a comprehensive overview of the past, present and future evolution characteristics of the Atlantic Meridional Overturning Circulation...
Despite their immense promise to solve new kinds of problems, today's quantum computers are inherently prone to error. A small perturbation in their surrounding environment— a change in temperature, pressure, or magnetic field, for instance—can disrupt their fragile computational building blocks, called qubits.
A study by the University of the Basque Country (UPV/EHU) makes a new technological appraisal of a northern gannet bone that displays complex peri-cylindrical decoration
A research team led by Prof. Qin Xiaoying from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has improved the thermoelectric performance of an n-type transition metal selenide, Bi2Te2.7Se0.3 (BTS), by incorporating MnSb2Se4 (MSS) nanoinclusions. Results were published in two articles in the Chemical Engineering Journal.
Quito, the capital city of Ecuador, is perched on the mountainous backbone of the Andes, which run through the center of this equatorial nation on the northwest shoulder of South America. Although February is the wet season, but it isn’t raining today so people lounge near a pond in Parque Alameda, with fountains spraying jetsContinue reading "A visit to Ecuador’s astronomical center" The post...
Processes inside human cells are tightly regulated in time and space by various enzymes and proteins. However, if processes become unbalanced—for example, because cells experience increased stress—these processes can also lead to diseases.
Arctic ground squirrels are unique among mammals. Their ability to keep from freezing even when body temperatures dip below that mark on the thermometer enables them to survive extreme winter climates. New research published in Science analyzes more than 25 years of climate and biological data. The findings include shorter hibernation periods and differences between male and female hibernation...
