New analysis offers insights into causes of persistent inequities affecting non-white scientists and their research

A team of NYU Abu Dhabi (NYUAD) researchers, including data and computational social scientists, is reporting new findings that highlight previously unknown ways through which non-white scientists suffer from inequities when it comes to the process of having their research considered, published, and cited, potentially hindering the advancement of their academic careers.

A persistent influence of supernovae on biodiversity

The number of exploding stars (supernovae) has significantly influenced marine life's biodiversity during the last 500 million years. This is the essence of a new study published in Ecology and Evolution by Henrik Svensmark, DTU space.

New possibilities in the theoretical prediction of particle interactions

How does the world look like at the smallest scales? This is a question scientists are trying to answer in particle collider experiments like the Large Hadron Collider at CERN in Switzerland. To compare the results of these experiments, theoretical physicists need to provide more and more precise predictions based on our current model for the interactions of fundamental particles, the so called...

Forests reduce health risks, new global report confirms

The global scientific evidence of the multiple types of benefits that forests, trees and green spaces have on human health has now been assessed by an international and interdisciplinary team of scientists. The outcome is presented in a report titled "Forests and Trees for Human Health: Pathways, Impacts, Challenges and Response Options" by the Global Forest Expert Panels (GFEP) Programme of the...

Unraveling nature's chorus: AI detects bird sounds in Taiwan's montane forests

Montane forests, known as biodiversity hotspots, are among the ecosystems facing threats from climate change. To comprehend potential impacts of climate change on birds in these forests, researchers set up automatic recorders in Yushan National Park, Taiwan, and developed an AI tool for species identification using bird sounds. Their goal is to analyze status and trends in animal activity through...

NASA seeks student ideas for moon landing dust control

As NASA and industry partners develop new human landing systems to transport astronauts from lunar orbit to the moon's surface and back as part of Artemis, the agency is asking university students to investigate solutions to one particularly dusty aspect of landing spacecraft on the lunar surface.

Earth's crustal stress can be inferred from fluid flow of fractures in deep boreholes

To gain a deeper understanding of a wide range of geological processes, such as plate tectonics, earthquakes and volcanic diking, we need to have a knowledge of both past and present in situ stress field. In particular, information on crustal in situ stress at various spatial and temporal scales is crucial in dealing with issues such as oil and gas extraction, geothermal development, carbon...

Researchers develop portable color-changing food spoilage sensor

When foods like fish, meat, and cheese decompose, they release a variety of low molecular weight organic nitrogen compounds known as biogenic amines (BAs). While the body uses BAs in small amounts in processes like hormone synthesis, ingesting large amounts of BAs from spoiled food can cause serious health problems.

A new and efficient particle resuspension prediction model based on quasi-static moment equilibrium

A team of researchers explored the resuspension mechanism of deposited particles under the action of airflow. Using advanced image detection technology and numerical simulation method, a particle resuspension model based on quasi-static moment equilibrium was developed. The model takes into account the influence of flow characteristics, particle morphology, and rough wall surface, which improves...

Bushfire safe rooms may save lives

QUT researchers have built and tested a bushfire safe room that exceeds current Australian standards and could keep people alive or protect valuables when evacuation is no longer an option.

People who catch Omicron are less likely to get Long Covid

Ever since the COVID-19 pandemic unfurled across the United Kingdom, hematologist John Willan has worried about the disease’s toll on his patients. In March 2020, Willan, who works at the University of Oxford and Wexham Park Hospital, began to track the hospital’s COVID-19 cases among people with leukemias, lymphomas, and other blood diseases. He counted not just the dozens of deaths,...

Novel probe helps to detect deep sea biological macromolecules

The phenomenon of chemically synthesized life in extreme deep-sea environment is an international research hotspot in deep-sea science and life science. However, due to the extremely low concentration of organic macromolecules such as extracellular metabolites synthesized by deep-sea chemicals and the complex surrounding environment, there is no in-situ detection technology so far.
