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.
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
Scientists develop new geochemical 'fingerprint' to trace contaminants in fertilizer
An international team of scientists has revealed high levels of toxic metals in global phosphate fertilizers using a isotopic variants of the element strontium as a tracer to uncover metals in soil, groundwater and possibly the food chain.
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.
Scale matters in determining vulnerability of freshwater fish to climate changes
A team explored the influence the spatial extent of research -- the geographical coverage of data collected -- has on evaluating the sensitivity of different fish species to climate change.
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
Scientists discover mechanism of sugar signaling in plants
A paper describes how the moving parts of a particular plant protein control whether plants can grow and make energy-intensive products such as oil -- or instead put in place a series of steps to conserve precious resources. The study focuses specifically on how the molecular
Research finds VISTA directly blocks T-cells from functioning in immunotherapy
A team of scientists and physicians have discovered that the immune checkpoint protein VISTA can directly turn off tumor-fighting T-cells during immunotherapy and resist treatment. The study explains that VISTA can bind to a protein called LRIG1 in T cells, which was previously
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. Studies on the remains of horses found at ancient burial sites in Russia and Lithuania show that they were brought overseas from Scandinavia utilizing expansive trade
Gut bacteria boost immune response to fight tumors
Researchers have found that a strain of gut bacteria can boost immune responses and enhance cancer immunotherapy to fight sarcoma tumors in mice.
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
Magnetic imprint on deconfined nuclear matter
Scientists have the first direct evidence that the powerful magnetic fields created in off-center collisions of atomic nuclei induce an electric current in 'deconfined' nuclear matter. The study used measurements of how charged particles are deflected when they emerge from the
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
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
