Peru's Operation Mercury stopped most illegal gold mining in one biodiversity hotspot—then the COVID-19 pandemic hit
The James Webb Space Telescope (JWST) recently imaged Supernova 1987A (also called SN 1987A), revealing a keyhole structure at its center. The supernova resides within the Large Magellanic Cloud (LMC), about 168,000 light-years from Earth, and was first noticed when researchers saw a new source of light in the LMC created by the death of a massiveContinue reading "JWST views Supernova 1987A"
Diamond materials as solar-powered electrodes: Spectroscopy shows what's important
Artisanal and small-scale gold mining is a lifeline for many who live in Madre de Dios, a region in southeastern Peru, where poverty is high and jobs are scarce. But the economic development in this part of the Amazon basin comes at a cost, as it causes deforestation, build up of sediment in rivers, and mercury contamination in nearby watersheds, threatening public health, Indigenous peoples, and...
Conceptual study looks at nanocapsules for scaling up the power of nanotechnology
It sounds like magic: photoelectrodes could convert the greenhouse gas CO2 back into methanol or N2 molecules into valuable fertilizer—using only the energy of sunlight.
Researcher uncovers how stereotypes about brilliance shape women's decisions to study psychology or philosophy
In a new study, researchers at the University of Missouri have created a proof of concept of a nanocapsule—a microscopic container—capable of delivering a specific "payload" to a targeted location.
Teacher well-being not a priority in schools, experts warn
Even though women in high school and college tend to outperform men academically, they still internalize the stereotype that brilliance is more linked to men. This belief affects their choice of major and perpetuates gender gaps in academic fields, according to a new study by a Florida State University researcher.
Study shows simulator, combined with app, helps teachers correct mistakes before entering classroom
Against a backdrop of funding shortages and recruitment issues across the education sector, two education experts argue that equipping leaders with more soft skills will improve mental health and well-being in school staff.
Quiet cables set to help reveal rare physics events
When pilots, surgeons or others with high-stakes professions are learning their craft, they have simulators with which to practice. Now, a new study shows that a simulator, when combined with software to provide data on performance, can help teachers learn what mistakes to avoid before working with working in a real classroom.
Researchers ready NASA's SPHEREX space telescope for 2025 launch
Imagine trying to tune a radio to a single station but instead encountering static noise and interfering signals from your own equipment. That is the challenge facing research teams searching for evidence of extremely rare events that could help understand the origin and nature of matter in the universe. It turns out that when you are trying to tune into some of the universe's weakest signals, it...
One in three children who've been in care system enter youth justice system, UK research shows
NASA's SPHEREx space telescope has been tucked inside a custom-built chamber on and off for the past two months undergoing tests to prepare it for its two-year mission in space. SPHEREx, which stands for Spectro-Photometer for the History of the universe, Epoch of Reionization and Ices Explorer, is set to launch into orbit around Earth no later than April 2025.
Jewel of the forest: New electric blue tarantula species discovered in Thailand
An unprecedented study of 2.3m children has found that one in three children born between 1996 and 1999 who had experience of the care system received a youth justice caution or conviction between the ages of 10 and 17, compared with just 4% of those without experience of care.
The Sun’s death could mean new life in the outer solar system
In an exciting discovery, a new species of tarantula with electric blue coloration was found in Thailand.

Evaluating the shear viscosity of different water models
The future red giant sun bakes planet Earth. Fsgregs/Wikimedia Commons In roughly 5 billion years, the Sun will run out of energy and drastically alter the solar system. Oceans will be baked dry. Entire planets will be consumed. And long-icy worlds will finally enjoy their day in the Sun. Our star is powered by nuclearContinue reading "The Sun’s death could mean new life in the outer solar...
Hundreds of weeds found illegally advertised online in Australia
Water is one of the most abundant substances on Earth and partakes in countless biological, chemical, and ecological processes. Thus, understanding its behavior and properties is essential in a wide variety of scientific and applied fields. To do so, researchers have developed various water models to reproduce the behavior of bulk water in molecular simulations.
Generative AI already being used in majority of college classrooms, according to new survey
Hundreds of weeds have been found advertised on a public online marketplace in Australia. Cacti and pond plants were among the most frequently advertised illegal weed species. These weeds are prohibited in Australia due to their harmful impact on the country's environment and agriculture. Despite this, a research team led by Jacob Maher discovered thousands of online advertisements for these...
Nanoparticle vaccine candidate shows promise against emerging tick-borne virus in early studies
A new report from Wiley suggests that generative artificial intelligence (AI) is already being used in the majority of college classrooms—and that number could climb quickly.
Two new species of ancient primates resembling lemurs identified
Cleveland Clinic researchers have used nanoparticles to develop a potential vaccine candidate against Dabie Bandavirus, formerly known as Severe Fever with Thrombocytopenia Syndrome Virus (SFTSV), a tick-borne virus that currently has no prevention, treatment or cure.
Profiling artemisinin's antimalarial mechanism: Research team reveals crucial target proteins
Fossil evidence from the Tornillo Basin in West Texas and the Uinta Basin in Utah reveals two new species of omomyids—a family of small-bodied early primates from the Eocene epoch. The findings also clarify previously disputed taxonomic distinctions among these primates, according to researchers from The University of Texas at Austin, Des Moines University in Iowa and Midwestern University in...
Avoiding the 'nothingburger' effect in government contractor mergers and acquisitions
Jigang Wang and colleagues have made significant progress in unraveling the antimalarial mechanisms of artemisinin (ART) and its derivatives. Their latest research, published in the journal Engineering, sheds light on the crucial target proteins and pathways of ART, providing valuable insights into combating malaria and addressing emerging ART resistance.
Conversations with plants: Can we provide plants with advance warning of impending dangers?
In love and business alike, the laws of attraction can be obscure. Companies pursue mergers and acquisitions (M&A) for a host of reasons ranging from gaining market share to gaming the tax system. In his recently published research, Brett Josephson, associate dean for executive development and associate professor of marketing at George Mason University, pondered one particularly mysterious M&A...

We could sequester CO2 by 're-greening' arid lands, plant scientists say
Researchers expand the use of ribosome profiling, also known as Ribo-seq, to understand protein production in cells
- 23/9/21 21:45
Reducing CO2 levels in the atmosphere will take more than cutting emissions -- we will also need to capture and store the excessive volumes of already-emitted carbon. A team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.
