☆ Microplastics may affect the weather, new study finds
▼ + stars: | 2023-11-15 | by ( Mary Gilbert | ) edition.cnn.com time to read: +4 min

Now, scientists have found that these tiny particles might even be able to influence the weather. Microplastics form when larger plastics break down, either by chemically degrading or physically wearing down into smaller pieces. The authors of Wednesday’s study found microplastics affect cloud formation, and clouds are of huge importance to the weather we experience. According to the study, microplastics can now be added to that list. Once the first water droplets cling to microplastics and other tiny particles, more water droplets are pulled together and clouds form.

It turns out the master artist was more experimental with his renowned “Mona Lisa” than previously thought — and was likely the creator of a technique seen in works created a century later, a new study suggests. By using X-ray diffraction and infrared spectroscopy, a team of scientists in France and Britain has detected a rare mineral compound within the iconic piece. The rare compound plumbonacrite was also found in "The Late Supper," as well as in several 17th-century works by Rembrandt. The “Mona Lisa,” like many other paintings from the 16th century, was created on a wood panel that required a thick base layer, Wallez said. The “Mona Lisa” and “The Last Supper” are two out of fewer than 20 known paintings Leonardo made in his lifetime.

PARIS (AP) — The “Mona Lisa” has given up another secret. The oil-paint recipe that Leonardo used as his base layer to prepare the panel of poplar wood appears to have been different for the “Mona Lisa," with its own distinctive chemical signature, the team of scientists and art historians in France and Britain discovered.

"Advanced recycling has immense potential to transform the plastic waste crisis," she said in a recent note to clients. It is a "silver bullet" for recycling plastic waste that can't be processed using traditional methods, she said. Ogundiya said investors have been warded off the theme by what she views as unfounded arguments around the maturity of advanced recycling technology. The idea has also been raised that there's an insufficient need for advanced recycling if plastic is banned. Of the two analysts surveyed by LSEG, one has a buy rating and one has a strong buy rating on Loop.

A tweet that has garnered at least 980 retweets reads: “Has anyone heard of this A-113 equals Adrenochrome? A113 AT PIXARInsider reported in February that references to the number A113 are in at least 23 Pixar movies, including its first studio film Toy Story (here). GOOGLEThe link between adrenochrome and A113 may stem from screenshots accompanying these claims on social media that show that searching the terms “a113 chemical” or “A-113 chemical” on Google brings up the Wikipedia page for adrenochrome.

☆ Forget TikTok claims: ‘Nature’s Ozempic’ is no such thing, experts say
▼ + stars: | 2023-07-04 | by ( Sandee Lamotte | ) edition.cnn.com time to read: +6 min

CNN —If TikTok and Reddit influencers are to be believed, the plant-based compound called berberine can be a replacement for such popular diabetes and weight loss drugs as Ozempic and Wegovy. Is berberine’s weight loss effect meaningful? Berberine may enhance the body’s natural production of GLP-1, or glucagon-like peptide 1, a gastrointestinal hormone that’s used in Ozempic and other new weight loss drugs. However, in terms of its weight loss benefits, they are modest at best,” he said. “Metformin lowers blood sugar, and berberine lowers blood sugar,” Levitt said.

Researchers conducted a study to find out how different human body odors can attract mosquitoes. The research used a 20-meter by 20-meter screened cage that contained hundreds of African malaria mosquitoes, according to the study. Despite the name, the mosquitoes were not infected with malaria, according to CNN, which first reported on the study. These tents are connected to the cage in a way that the human body odor can be safely fed to the mosquitoes. Researchers found that mosquitoes gravitated to human body odor with "increased relative abundances of the volatile carboxylic acids," including butyric acid.

☆ Opinion | The Evidence Is In: Science Should Be Judged on the Merits

Consider the increasingly widespread practice of appending a “positionality statement” to one’s research. This is an explicit acknowledgment by the author of an academic paper of his or her identity (e.g., “nondisabled,” “continuing generation”). Positionality statements were first popular in the social sciences and are now spreading to the hard sciences and medicine. The purpose of a citation in an academic publication is to substantiate claims and offer the most relevant supporting research. Many prominent science journals now recommend that before submission, authors run their papers through software programs that detect any citation bias.

☆ No, artificial vanilla flavoring doesn't come from beaver butts. Flavor scientists explain.
▼ + stars: | 2023-03-08 | by ( Rebecca Strong | ) www.businessinsider.com time to read: +9 min

It's a myth that artificial vanilla flavoring comes from castoreum extracted from beaver castor sacs. Flavor chemists explain that artificial vanilla flavor is made from synthetic vanillin. He said, many food companies use artificial flavors because extracting natural flavors from fruits and other plants is labor-intensive and expensive. For example, a chemical appropriately named "raspberry ketone" — which also occurs naturally in raspberries — is an essential component of artificial raspberry flavor. Scientists are still working out how to replicate these flavor volatiles, which is why artificial vanilla flavors tend to lack complexity.

Scientists discovered a compound in pseudomonas bacteria that can effectively kill certain fungi. The fungus killer was named after actor Keanu Reeves by German researchers. Researchers at the Leibniz Institute in Germany found certain bacteria naturally contained compounds effective at killing fungi that affect plants and humans. The scientists named them keanumycins A, B, and C — after actor Keanu Reeves. The keanumycins were most effective at killing Botrytis cinerea — a fungus that produces gray mold rot.

☆ A new generation of airships is taking to the skies

It’s an airship, and French aeronautics company Flying Whales hopes its hybrid-electric, helium-lift vessel will change the shape of sustainable transport. Flying Whales' airships, pictured here in a render, could access remote locations without roads, railways or airports. That’s why most companies, including Flying Whales and LTA Research, are using helium, which is non-flammable. Prentice is also the founder and president of BASI, a Manitoba-based company specializing in airships adapted for cold climates. Flying Whales expects to test its first airship at the end of 2025, with commercial operations beginning in 2027 once the airship is certified.

Ulterior, ei au aprofundat aceste studii încercând să afle dacă şi particule mai mari de microplastic ar putea fi detectate, în cazul în care acestea pătrund în ţesuturile umane. Ne aflăm în prezent în poziţia în care putem defini mai bine poluarea cu plastic în corpul uman”, a declarat Halden. Şi, la acest moment, nu ştim dacă acest plastic este doar o pacoste sau dacă reprezintă un pericol la adresa sănătăţii umane, a adăugat cercetătorul. ”În prezent, nu există o metodă analitică ideală pentru cuantificarea particulelor de microplastic din ţesuturile umane”, a spus Dick Vethaak de la centrul de cercetare Deltares din Olanda. ”Marea întrebare” pentru cercetările viitoare este, în opinia lui Wright, dacă microparticulele de plastic au vreun impact asupra sănătăţii umane.
