Coral reefs around the world are under threat because of climate change, overfishing, pollution, and more. Now, researchers reporting in the journal One Earth on September 17 offer the first comprehensive global look at what these impacts on coral reefs mean for ecosystem services, the ability of the reef to provide essential benefits and services to humans. Overall, the findings show that the significant loss in coral reef coverage has led to an equally significant loss in the ability of the […]

In 2019–2020, wild Australian bushfires ravaged millions of hectares, claimed 33 lives and destroyed 3,113 houses, leaving most of Australia traumatized amid the ashes. But as a recent study by researchers from the University of Wollongong points out, adequate planning could save people's lives and better protect their homes.

Ben Merriman has experienced all sides of academic publishing as an author, journal editor and reviewer. That experience, coupled with his research in administrative structures' role in resolving policy conflicts, led the University of Kansas assistant professor public affairs & administration to explore the history of peer review in social sciences in a study for The American Sociologist. Merriman's study explores the historical emergence of major elements of editorial peer review, its […]

Facebook officials had internal research in March 2020 showing that Instagram—the social media platform most used by adolescents—is harmful to teen girls' body image and well-being but swept those findings under the rug to continue conducting business as usual, according to a Sept. 14, 2021, Wall Street Journal report.

New research released today by the nonpartisan California Policy Lab (CPL) shows that as the COVID-19 pandemic disrupted daily lives, crime in California and across the country also changed in dramatic ways. CPL analyzed data on violent and property crime in 2020 as compared to 2019, and compared California to the rest of the U.S.

ESA confirmed a contract signature yesterday with Surrey Satellite Technology Ltd (SSTL) to be the main customer for their Lunar Pathfinder satellite launching in 2024 that will provide communications services around the moon.

Verifying that a satellite will resist the sheer noise of the rocket launching it into orbit is a very important test that every mission must successfully pass.

NOX (X=1 or 2) emitted from stationery/mobile sources are conventionally deemed as notorious, anthropogenic precursors of ultrafine particulate matters (PM2.5) because NOX can undergo a series of SO2-assisted photochemical transformative stages to finally evolve PM2.5 functioning as an air pollutant. Recently, a research group in South Korea rectifies the general notion of NOX (vide supra) by proposing an interesting means to exploit NOX in creative fashion.

Some of the most well-known and feared aspects of climate change are its potential effects on weather patterns and how this could accelerate the melting of natural ice. Research has already proved that the area of sea-ice in the Arctic is rapidly declining due to global warming, and that temperature and moisture content across the Arctic have changed substantially. Unfortunately, understanding exactly how these changes affect cloud formation in the region is very challenging, and cloud […]

Northwestern University researchers assessing the response to COVID-19 for child care programs in Illinois have found the state's efforts to bolster child care access to first responders while stabilizing the market were equitable and largely successful.

Interferometers are widely used in various high spatial resolution imaging techniques to extend the diffraction limit. However, the conventional interferometric methods only work when the photons have the same wavelength.

The Queensland Police Service (QPS) is expected to begin a trial using artificial intelligence (AI) to determine the future risk posed by known domestic violence perpetrators.

Researchers at the University of Illinois Urbana-Champaign watched fragments of two meteors as they ramped up the heat from room temperature to the temperature it reaches as it enters Earth's atmosphere and made a significant discovery. The vaporized iron sulfide leaves behind voids, making the material more porous. This information will help when predicting the weight of a meteor, its likelihood to break apart, and the subsequent damage assessment if it should land.
