Slow Response to Bird Flu in Cows Worries Scientists
The H5N1 virus is a long way from becoming adapted to humans, but limited testing and tracking mean we could miss danger signs
Scientists develop new geochemical 'fingerprint' to trace contaminants in fertilizer
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.
Tracing the history of perturbative expansion in quantum field theory
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
Study reveals how a sugar-sensing protein acts as a 'machine' to switch plant growth—and oil production—on and off
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 things—and potentially how to change its effects. Biochemists at the U.S. Department of Energy's (DOE)
Researchers develop world's smallest quantum light detector on a silicon chip
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
How heat waves are affecting Arctic phytoplankton
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
Horse remains show Pagan-Christian trade networks supplied horses from overseas for the last horse sacrifices in Europe
Horses crossed the Baltic Sea in ships during the Late Viking Age and were sacrificed for funeral rituals, according to research from Cardiff University.
Study examines low-permittivity dielectric ceramics for microwave/millimeter-wave communication
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
New feather mite species discovered on the endangered Okinawa rail
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
An SEC mystery: What's the deal with voluntary filers?
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
Research: Technology is changing how companies do business
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 chains—specifically the way goods are made and distributed.
Canada's wildfire season begins
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.
Earth from space: New Zealand's North Island
Captured on 7 May 2024, this Copernicus Sentinel-2 image shows part of New Zealand's North Island.
How does the US know that forced labor is happening in China? A supply chain expert weighs in
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.
Feeding native ecosystems with waste
UC researchers are pioneering the use of treated sewage to restore native plants on Te Pātaka-o-Rākaihautū Banks Peninsula.
Overlooked coastal marine ecosystems can capture more carbon dioxide than previously thought, finds study
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
Ariane 6 launches Replicator for 3D printing in open space
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
Researchers unlock water-saving potential of wheat with TabHLH27 balancing stress and growth
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
Researchers confirm scale matters in determining vulnerability of freshwater fish to climate changes
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 supersede their own at sentencing: Report
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).
Researchers discuss current state of homophobia, transphobia and biphobia
Gender-neutral bathrooms, conversion therapy and Quebec's advisory committee on gender identity have been in the news lately. These are polarizing, hot-button issues.
Ion irradiation offers promise for 2D material probing
Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast electronic processes can be probed by irradiating the
Linking leaf elemental traits to biomass across forest biomes in the Himalayas
The growth, development, and functioning of plants in various environments depend on multiple elements. However, our understanding of how the element concentrations in leaves that are associated with plant functioning and adaptation affect biomass in tree communities along
Furry thieves are running loose in a Maine forest, research shows
Scattered across the Penobscot Experimental Forest are veritable treasure troves for its denizens, each containing riches beyond comprehension. These caches do not contain gold or jewels—they're filled with eastern white pine seeds and were placed by a team of researchers at
Research finds human activity over natural inputs determines the bacterial community in an ice core
The Tibetan Plateau (TP) has the third-largest number of glaciers after the Antarctic and Greenland. Bacteria, deposited on glacier surfaces through dry and wet deposition, undergo in-situ growth and are subsequently preserved in ice cores following environmental selection
