We’ve only just begun to examine the racial disparities of long covid
Liza Fisher is preparing for a busy day. In about an hour, her mother will drive her to a clinic, where she will receive IV fluids and iron treatments for her anemia. When the IV bag is empty, she’ll head to an adaptive gym, where she’ll don compression pants and take a class for people…
Super-resolved coherent Raman spectroscopy with quantum light
In recent years, entangled photons—a popular quantum light source—have been widely used in quantum imaging, optical interferometry, quantum computing, quantum communication, and other fields. Spontaneous parametric down-conversion generates the entangled photon pairs with conserved energy and momentum, so that the quantum correlation in space and time is encoded. Such a property enables a...
New study finds that natural gas leaked from interstate pipelines contains hazardous air pollutants and carcinogens
Natural gas transported by interstate pipelines contains hazardous air pollutants and known human carcinogens, according to a first of its kind study published in Environmental Research Letters by researchers at the nonprofit research institute PSE Healthy Energy.
Multifunctional porous conductive membranes help microbes eat their way to a faster carbon dioxide conversion
Microporous conductive membranes developed at KAUST are expected to help shape the future of microbial electrosynthesis for CO2 conversion technologies. The membranes simultaneously stimulate the growth of CO2-eating microbes and aid separation of the biochemical products.
Resonance Raman scattering provides new ways for high-sensitivity temperature probing
Thermal scientists from the Iowa State University, Shenzhen University, and Shanghai University of Engineering Science, have developed a new thermal probing technique based on the ratio of two resonance Raman scattering peak intensities.
Energy storage materials built from nano-sized molecular blocks
Molecules of the rare metallic element niobium can be used as molecular building blocks to design electrochemical energy storage materials. Mark Rambaran, Department of Chemistry at Umeå University, presents in his thesis a method for producing solid materials from aqueous solutions containing nano-sized niobium molecules, called polyoxoniobates.

Not even soaking rain can ease fire risk in a California hit by record heat, dry landscape
A summer of drought, extreme heat and deadly wildfires will end with much-needed rain this week in parts of California, but it is unlikely to douse the threat of wind-driven fires this fall in a state scarred by record-setting heat waves and bone-dry landscapes.
How disclosing advertising spending can reduce investor and analyst uncertainty and possibly enhance firms' valuations
Researchers from Bocconi University, Singapore Management University, and INSEAD published a new article in the Journal of Marketing that shows that disclosure of advertising spending significantly lowers investor and analyst uncertainty and allows them to better understand how a firm is achieving its financial performance.
When school feels 'like prison' test scores, college attendance drop
Students at high schools with prominent security measures have lower math scores, are less likely to attend college and are suspended more compared to students in schools with less surveillance, finds a new Johns Hopkins University study.
Researchers estimate there are 2.5m ants for every human across the planet
The analysis is based on 489 studies of ant populations spanning every continent where the insects liveThe world’s human population is forecast to surpass 8bn in the coming months. Compared with ants, that is a mediocre milestone.Researchers have made the most thorough assessment to date of the global population of ants and the estimated total is a mind-blowing 20 quadrillion of them, or...
The role of overconfidence and perceived ability in preferences for income equality
Overconfidence in one's ability is not uncommon among humans. It can be observed in areas ranging from driving ability and productivity to calculating returns on investment projects. Overconfidence can also lead people to think that they aren't earning as much as they think they can.
Workplace trauma can affect anyone in any occupation. How can we deal with it? | Ashwini Padhi
It doesn’t just happen to emergency or frontline workers, and can stem from accidents, bullying, and even severe stressThe modern mind is a column where experts discuss mental health issues they are seeing in their workWith no apparent signs of trauma, Kate* is by all appearances a put-together woman in her early 40s: professional, well-spoken, immaculate and confident.When I ask her what has...
How two isomers of [IrC₄H₂]⁺ independently react with either methane or water
This study was led by Prof. Shaodong Zhou (College of Chemical and Biological Engineering, Zhejiang University) and Prof. Xiao-Nan Wu (Department of Chemistry, Fudan University). The experiments were performed by using an ion trap mass spectrometer equipped with a laser vaporization−supersonic expansion ion combined with quantum chemical calculations.
Plastic degradation in the ocean contributes to its acidification
A new study led by the Institut de Ciències del Mar (ICM-CSIC) in Barcelona has revealed that plastic degradation contributes to ocean acidification via the release of dissolved organic carbon compounds from both the plastic itself and its additives.
New chemistry happens when dust meets pollution
It is a new chemistry found to take place in a cloud droplet, a wet aerosol, or on the surface of a dust particle. All that it takes to get started is natural events like dust storms, ocean wave action, volcanic eruptions, and wildfires, which increase the amount of aerosols in the atmosphere.
Earth-like exoplanets unlikely to be another 'pale blue dot'
When searching for Earth-like worlds around other stars, instead of looking for the "pale blue dot" described by Carl Sagan, new research suggests that a hunt for dry, cold "pale yellow dots" might have a better chance of success. The near balance of land-to-water that has helped life flourish on Earth could be highly unusual, according to a Swiss-German study presented at the Europlanet Science...

How retail is using AI to prevent fraud
Retailers face an evolving landscape of fraud tactics each day. It’s why companies are increasingly turning to AI to try and catch threat patterns never seen before, and block attacks before they ever happen. While this approach lends itself to efficiency, it’s also one that relies on increasingly complex data profiles of consumers. In this…
Geoengineering could destabilize tropical peat soils
The Earth is warming up at an increasing rate. A contributing factor is carbon dioxide (CO2), a greenhouse gas, prompting researchers to investigate methods to reduce levels. In her dissertation at the University of Bremen, Dr. Alexandra Klemme discovered that the "enhanced weathering" strategy—which, until now, has been considered a promising method—is not suitable for removing CO2 from...
Despite frequent sightings, red squirrel habitats in Berlin are small and fragmented
Red squirrels are among the most commonly sighted wildlife in European big cities such as Berlin. However, their habitats are more reminiscent of a patchwork quilt full of challenges, a team of scientists led by the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) found out, with the help of computer models and red squirrel sightings by citizen scientists. The models link sightings to...
Home ownership leads to less happiness than expected
We aren't very good at predicting what will make us happy. That is one finding from a study by Basel economists. They investigated the effects of purchasing a home on life satisfaction. The positive effect on happiness did not last as long as people expected.
Artificial intelligence spots pests in trail cams, and tracks indigenous plants from orbit
A new paper published in the Journal of the Royal Society of New Zealand highlights the importance of having multiple open-source data sets available for environmental research.
