An international team of scientists has uncovered toxic metals in mineral phosphate fertilizers worldwide by using a new tool to identify the spread and impact of such contaminants on soil, water resources, and food supply.
Perturbative expansion is a valuable mathematical technique which is widely used to break down descriptions of complex quantum systems into simpler, more manageable parts. Perhaps most importantly, it has enabled the development of quantum field theory (QFT): a theoretical framework that combines principles from classical, quantum, and relativistic physics, and serves as the foundation of the Standard Model of particle physics.
Proteins are molecular machines, with flexible pieces and moving parts. Understanding how these parts move helps scientists unravel the function a protein plays in living thingsβand potentially how to change its effects. Biochemists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and colleagues at DOE's Pacific Northwest National Laboratory (PNNL) have published a new example of how one such molecular machine works.
Researchers at the University of Bristol have made an important breakthrough in scaling quantum technology by integrating the world's tiniest quantum light detector onto a silicon chip. The paper, "A Bi-CMOS electronic photonic integrated circuit quantum light detector," was published in Science Advances.
The basis of the marine food web in the Arctic, the phytoplankton, responds to heat waves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic, which were recently conducted at the Alfred Wegener Institute's AWIPEV Station. The phytoplankton's behavior primarily depends on the cooling phases after or between heat waves, as shown in a study just released in the journal Science Advances.
Horses crossed the Baltic Sea in ships during the Late Viking Age and were sacrificed for funeral rituals, according to research from Cardiff University.
Microwave dielectric ceramics are the cornerstone of wireless communication devices, widely utilized in mobile communications, satellite radar, GPS, Bluetooth, and WLAN applications. Components made from these ceramic materials, such as filters, resonators, and dielectric antennas, are extensively used in wireless communication networks.
A research group led by Dr. Tsukasa Waki of Toho University and Professor Satoshi Shimanono of Hosei University have discovered a new mite species, Metanalges agachi, which is thought to clean the feathers of the endangered Okinawa rail, endemic to the northern part of Okinawa Island, Japan.
Companies tend not to clamor for more regulatory oversight, as a general rule. One remarkable exception would be the relatively small group of companies that voluntarily file with the Securities and Exchange Commission (SEC). Although not required to file due to their small size or private ownership, these companies do so willingly, at considerable time and expense.
In the fast-paced world of modern business, technology plays a crucial role in shaping how companies operate. One area where this impact is particularly significant is in the organization of production chainsβspecifically the way goods are made and distributed.
Wildfire season has arrived in full force in Canada, prompting evacuation orders and alerts in several towns in British Columbia and Alberta due to the danger of uncontrolled blazes.
The Biden administration has added 26 more companies to the list of Chinese textile traders and manufacturers whose goods are blocked from entering the United States because of their alleged ties to forced labor.
The ability of coastal ecosystems to capture and store carbon dioxide has been underestimated. The question is not just about seagrass meadows and mangrove forests, which have already attracted attention, but a wide range of different ecosystems whose carbon storing function has been overlooked. However, for these areas to be able to combat climate change, they must be protected.
Europe's newest rocket soon launches, taking with it many space missions each with a unique objective, destination and team at home, cheering them on. Whether into Earth orbit to look back and study Earth, peer out to deep space or test important new technologies, Ariane 6's first flight will showcase the versatility and flexibility of this impressive, heavy-lift launcher.
Wheat plays a critical role in global food security, but water scarcity in arid and semi-arid regions hinders its efficient production, suggesting significant opportunities for water saving. Therefore, understanding the genes that control wheat's drought tolerance and water use efficiency is critical for improving genetic resilience and breeding water-efficient varieties.
The silver chub isn't considered sensitive to climate change on a national scale, but context matters. For example, if climate change sensitivity is evaluated in only one region of the United States, the freshwater fish appears quite a bit more susceptible.
Victim-survivors of rape and sexual assault feel perpetrators' rights and interests supersede their own at sentencing, according to new research led by the Scottish Center for Crime and Justice Research (SCCJR).
