Published Zika infection in pregnant macaques slows fetal growth
(via sciencedaily.com) Original source Zika virus infection in pregnant rhesus macaques slows fetal growth and affects how infants and mothers interact in the first month of life, according to a new study. The work has implications for both humans exposed to Zika virus and for other viruses that can cross the placenta, including SARS-CoV2, responsible for the COVID-19 pandemic.
Published Using sound to test devices, control qubits
(via sciencedaily.com) Original source Researchers have developed a system that uses atomic vacancies in silicon carbide to measure the stability and quality of acoustic resonators. What's more, these vacancies could also be used for acoustically-controlled quantum information processing, providing a new way to manipulate quantum states embedded in this commonly-used material.
Published Rider on the storm: Shearwater seabird catches an 11 hour ride over 1,000 miles in a typhoon
(via sciencedaily.com) Original source New research suggests that increasingly severe weather driven by climate change may push oceangoing seabirds to their limits.
Published Clinical trials could yield better data with fewer patients thanks to new tool
(via sciencedaily.com) Original source Mathematicians have invented a new statistical tool to analyze multiple outcomes from clinical trials, replacing the 60-year-old standard tool that could only look at binary outcomes (survived/ did not survive). This will allow researchers to ask more complex research questions with trials that involve fewer patients, thereby streamlining the process of getting effective treatments to patients.
Published Can AI grasp related concepts after learning only one?
(via sciencedaily.com) Original source Researchers have now developed a technique that advances the ability of these tools, such as ChatGPT, to make compositional generalizations. This technique, Meta-learning for Compositionality, outperforms existing approaches and is on par with, and in some cases better than, human performance.
Published Breakthrough T cell discovery has huge potential for engineering custom immune responses
(via sciencedaily.com) Original source In a breakthrough discovery that changes how we understand T cells and with implications of how we can better engineer custom immune responses to fight disease, researchers showed that the different disease-fighting functions of different T cells are determined by the genetically encoded T-cell receptor sequence that are unique to those cells.
Published Highest-resolution single-photon superconducting camera
(via sciencedaily.com) Original source Researchers have built a superconducting camera containing 400,000 pixels -- 400 times more than any other device of its type. Having more pixels could open up many new applications in science and biomedical research.
Published Massive space explosion observed creating elements needed for life
(via sciencedaily.com) Original source Scientists have observed the creation of rare chemical elements in the second-brightest gamma-ray burst ever seen -- casting new light on how heavy elements are made.
Published Scientists discover molten layer covering Martian core
(via sciencedaily.com) Original source NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
Published On the trail of the silver king: Researchers reveal unprecedented look at tarpon migration
(via sciencedaily.com) Original source New research unveils a dataset, gathered over five years, that gives the finest-grained detail into the timing and spatial extent of tarpon migration. The work leveraged networks of thousands of acoustic receivers that tracked 200 tarpon over more than five years. One of the key findings is that there are two distinct subgroups of tarpon, which has immediate implications for efforts to conserve the fish, known to anglers as the 'Silver King.'
Published New method to analyze implications of large-scale flood adaptation
(via sciencedaily.com) Original source In a test of their new analysis tool, researchers show where 'moving up' or 'moving over' may make the most sense for those affected by the 2022 Pakistan flood, and what costs it would entail.
Published First detection of heavy element from star merger
(via sciencedaily.com) Original source A team of scientists has used multiple space and ground-based telescopes to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.
Published In Prehispanic Cancun, immigrants were treated just like Maya locals
(via sciencedaily.com) Original source Ancient people immigrated to Cancun Island and were treated just like locals, according to a new study.
Published Climate change likely impacted human populations in the Neolithic and Bronze Age
(via sciencedaily.com) Original source Human populations in Neolithic Europe fluctuated with changing climates, according to a new study.
Published Something in the eyes: Java Sparrows in love show enhanced eye rings
(via sciencedaily.com) Original source Pair-bonded Java sparrows show enlarged eye rings to signal breeding readiness.
Published UK air pollution regulations will reduce deaths, but do little to protect ecosystems
(via sciencedaily.com) Original source Existing air pollution regulations will reduce thousands of premature adult deaths in the UK, but even the most effective technically feasible actions, which will save thousands more lives, will do little to protect the country's sensitive ecosystems, find researchers.
Published 'Dim-witted' pigeons use the same principles as AI to solve tasks
(via sciencedaily.com) Original source A new study provides evidence that pigeons tackle some problems just as artificial intelligence would -- allowing them to solve difficult tasks that would vex humans.
Published Single model predicts trends in employment, microbiomes, forests
(via sciencedaily.com) Original source Researchers report that a single, simplified model can predict population fluctuations in three unrelated realms: urban employment, human gut microbiomes and tropical forests. The model will help economists, ecologists, public health authorities and others predict and respond to variability in multiple domains.
Published Achieving large and uniform particle sizes
(via sciencedaily.com) Original source Dispersions of polymer particles in a liquid phase (latexes) have many important applications in coatings technology, medical imaging, and cell biology. A team of researchers has now developed a method to produce stable polystyrene dispersions with unprecedentedly large, and uniform, particle sizes. Narrow size distributions are essential in many advanced technologies, but were previously difficult to produce photochemically.
Published Sediment core analysis supports new epoch characterized by human impact on planet
(via sciencedaily.com) Original source Scientists analyzed open-source data to track vegetation changes across North America since the end of the Pleistocene Epoch, and conclude that humans have had as much of an impact on the landscape as the retreat of the glaciers at the end of the Ice Age.
