Better medical record-keeping needed to fight antibiotic overuse
A lack of detailed record-keeping in clinics and emergency departments may be getting in the way of reducing the inappropriate use of antibiotics, a pair of new studies suggests. In one of the studies, about 10% of children and 35% of adults who got an antibiotic prescription
Global life expectancy to increase by nearly 5 years by 2050 despite geopolitical, metabolic, and environmental threats
The latest findings forecast that global life expectancy will increase by 4.9 years in males and 4.2 years in females between 2022 and 2050. Increases are expected to be largest in countries where life expectancy is lower, contributing to a convergence of increased life
Modern plant enzyme partners with surprisingly ancient protein
Scientists have discovered that a protein responsible for the synthesis of a key plant material evolved much earlier than suspected. This new research explored the origin and evolution of the biochemical machinery that builds lignin, a structural component of plant cell walls
Clinicians report success with first test of drug in a patient with life-threatening blood clotting disorder
A recombinant form of human ADAMTS13 approved for a different condition helped to save the life of a young mother with immune thrombotic thrombocytopenic purpura.
Physicists propose path to faster, more flexible robots
Physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.
Repeat COVID-19 vaccinations elicit antibodies that neutralize variants, other viruses
A study has found that repeat vaccination with updated versions of the COVID-19 vaccine promotes the development of antibodies that neutralize a wide range of variants of the virus that causes COVID-19, as well as related coronaviruses.
Sweet taste receptor affects how glucose is handled metabolically by humans
The sweet-taste receptor might be the first stop in a metabolic surveillance system for sugar. The receptor is also expressed in certain intestinal cells, where it may facilitate glucose absorption and assimilation, as part of this system. A team found that stimulation and
How heatwaves are affecting Arctic phytoplankton
The basis of the marine food web in the Arctic, the phytoplankton, responds to heatwaves much differently than to constantly elevated temperatures. This has been found by the first targeted experiments on the topic. The phytoplankton's behavior primarily depends on the cooling
A Model Toadlet
A tiny, charismatic frog in Brazil is revealing secrets of a killer fungus. The post A Model Toadlet appeared first on Nautilus .
Keto diet may accelerate organ ageing
In mice, a ketogenic diet increases the build-up of zombie-like cells in the heart, kidney, lungs and brain, which can accelerate organ ageing and lead to health problems
There Is Too Much Trash in Space
Debris from spacecraft threatens the burgeoning space economy. We need a global agreement to keep space clean
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
