Are Skittles Toxic from Titanium Dioxide?
A recent lawsuit claims a chemical called titanium dioxide, used in Skittles candies, harms people. It’s hard to find strong evidence for that, however.....»»
Simple new process stores carbon dioxide in concrete without compromising strength
By using a carbonated—rather than a still—water-based solution during the concrete manufacturing process, a Northwestern University-led team of engineers has discovered a new way to store carbon dioxide (CO2) in the ubiquitous construction materi.....»»
Air So Polluted It Can Kill Isn’t Being Taken Seriously Enough
Toxic air kills over half a million children every year, yet only once has air pollution been listed as a cause of death on a death certificate......»»
Engineers produce the world"s first practical Titanium-sapphire laser on a chip
As lasers go, those made of Titanium-sapphire (Ti:sapphire) are considered to have "unmatched" performance. They are indispensable in many fields, including cutting-edge quantum optics, spectroscopy, and neuroscience. But that performance comes at a.....»»
National park wild boar contain five-times more toxic PFAS than humans allowed to eat, study finds
Wild boar in a European national park have been found to contain levels of toxic PFAS "forever chemicals" nearly five-times higher than is allowed to be sold in meat for human consumption under EU law, according to a new study......»»
PFAS "forever" chemical laws need an overhaul—recent court rulings highlight the loopholes
As awareness of toxic, synthetic chemical pollution from per- and polyfluorinated substances (PFAS) increases, more legal settlements in billion dollar amounts are being made between chemical companies and public water suppliers, both in the US and E.....»»
Sediments reveal the ancient ocean during a mass extinction event
About 183 million years ago, volcanic activity in modern South Africa unleashed an estimated 20,500 gigatons of carbon dioxide (CO2) into the ocean–atmosphere system over a period of 300 to 500 thousand years. Known as the Toarcian Oceanic Anoxic E.....»»
Your wig could be poisoning you: Study finds pesticides and other toxic chemicals in synthetic hair in Nigeria
Well-groomed hair is a symbol of beauty for many black African women. Natural hair requires special care and attention, though, which can be time consuming. Wigs (human or synthetic hair), weave-ons and other artificial hair extensions offer women an.....»»
New study confirms forever chemicals are absorbed through human skin
A study of 17 commonly-used synthetic 'forever chemicals' has shown that these toxic substances can readily be absorbed through human skin......»»
Scientists explore the vast reservoir of dissolved organic matter in oceans
Few things last very long in the world of the open oceans, it would seem. In the light-filled surface layer, microscopic algae convert carbon dioxide and water into biomass via photosynthesis. Individual cells vanish in a matter of hours or days, ing.....»»

Novel catalysts for improved methanol production using carbon dioxide dehydrogenation
Encapsulating copper nanoparticles within hydrophobic porous silicate crystals has been shown by scientists at Tokyo Tech to significantly enhance the catalytic activity of copper-zinc oxide catalysts used in methanol synthesis via CO2 hydrogenation......»»
Why scientists are intrigued by air in NASA"s Mars sample tubes
Atmospheric scientists get a little more excited with every rock core NASA's Perseverance Mars rover seals in its titanium sample tubes, which are being gathered for eventual delivery to Earth as part of the Mars Sample Return campaign. Twenty-four h.....»»
AI can help forecast toxic "blue-green tides"
A team of Los Alamos National Laboratory scientists plan to use artificial intelligence modeling to forecast, and better understand, a growing threat to water caused by toxic algal blooms. Fueled by climate change and rising water temperatures, these.....»»
Researchers harvest acid from seawater to feed beneficial algae
From the air you breathe to the seafood you eat, marine algae have some involvement—they consume carbon dioxide and produce oxygen through photosynthesis and feed fish and shellfish. One day, marine algae could also be used to make widely available.....»»
Giant deep-sea vent tubeworm symbionts use two carbon fixation pathways to grow at record speeds
In the deep-sea environment of the East Pacific Rise, where sunlight does not penetrate and the surroundings are known for their extreme temperatures, skull-crushing pressures, and toxic compounds, lives Riftia pachyptila, a giant hydrothermal vent t.....»»
Atmospheric sulfur dioxide levels hit historic high in Scotland following Icelandic volcanic eruption
Edinburgh, no stranger to an occasional haze, experienced an unprecedented atmospheric event on 31 May, unlike any seen over the past 30 years. While sea haar from the North Sea often blankets Scotland's capital, the haze observed that Friday felt di.....»»
Study finds human-caused nitrous oxide emissions grew 40% from 1980–2020, greatly accelerating climate change
Emissions of nitrous oxide—a greenhouse gas more potent than carbon dioxide or methane—continued unabated between 1980 and 2020, a year when more than 10-million metric tons were released into the atmosphere primarily through farming practices, a.....»»
Scientists engineer yellow-seeded camelina with high oil output
Efforts to achieve net-zero carbon emissions from transportation fuels are increasing demand for oil produced by nonfood crops. These plants use sunlight to power the conversion of atmospheric carbon dioxide into oil, which accumulates in seeds. Crop.....»»
