Rare compound detected in the ‘Mona Lisa’ reveals a new secret, study says

Published Fri, 21 Feb 2025 21:38:02 GMT

(CNN) — Leonardo da Vinci was a painter, inventor and anatomist, to name just a few of his talents — and now, you can add innovative chemist to the polymath’s many gifts. 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 finding provides fresh insight into how the work from the early 1500s was painted, according to the study recently published in the Journal of the American Chemical Society.Along with lead white pigment and oil, the compound — known as plumbonacrite — was found in the base layer of the paint. A study published in 2019 had identified the mineral in several 17th-century works by Rembrandt, but researchers had not come across ...

Quartz crystals detected swirling in an exoplanet’s atmosphere

Published Fri, 21 Feb 2025 21:38:02 GMT

(CNN) — Astronomers using the James Webb Space Telescope have for the first time detected tiny quartz crystals containing silica — a common mineral on Earth — within the atmosphere of a blazing hot exoplanet.It’s likely that the nanoparticles of silica, which on Earth appears in beach sands and is used to produce glass, swirl from the clouds of the exoplanet, known as WASP-17b, according to the researchers.First discovered in 2009, WASP-17b is a gas giant planet located 1,300 light-years from Earth. It has a volume more than seven times that of Jupiter, making it one of the largest exoplanets known to astronomers.The researchers detected the the quartz nanoparticles in high-altitude clouds using Webb’s Mid-Infrared Instrument, according to new research published Monday in The Astrophysical Journal Letters.“We were thrilled,” said lead study author David Grant, a researcher at the University of Bristol, in a statement. “We knew from Hubble observations that there must be ae...

Germany’s Scholz demands probe into Gaza hospital strike

Published Fri, 21 Feb 2025 21:38:02 GMT

German Chancellor Olaf Scholz said Wednesday that an explosion at a Gaza hospital must be investigated “very thoroughly,” after competing claims from Israel and Hamas about who blew up the site, killings hundreds, on Tuesday night.At least 500 people were killed at the al-Ahli hospital in Gaza after a massive blast, according to local health authorities linked to the Hamas militant group. Hamas blamed an Israeli air strike, while the Israeli military said a rocket misfired by other Palestinian militants had caused the explosion. Speaking in Cairo on Wednesday, Scholz cautioned that “we still do not know exactly what happened,” and stressed: “It is important that this incident is investigated very thoroughly.”Scholz expressed his condolences to the victims and their families, and said: “Yet this incident also makes it clear: Hamas brought terrible suffering to the citizens of Israel with its horrific terrorist attack on October 7, and as a result, much s...

EU troops storm the beaches as bloc aims to be military player

Published Fri, 21 Feb 2025 21:38:02 GMT

ABOARD THE FRENCH HELICOPTER CARRIER TONNERRE — It’s not yet a European army, but it’s getting close. This week in the south of Spain, the European Union is holding its first live military exercise — an effort to show the world it’s a serious security and defense player that can operate without NATO. Air, land and maritime armed forces from nine EU countries will land on a beach to rescue a fictitious European ally called Seglia that’s asking for help to deal with a rapidly deteriorating security situation caused by a violent extremist group. Spanish troops will play the enemy forces. Until Sunday, armies that don’t speak the same language and don’t use the same military equipment need to work together. About 2,800 personnel are taking part — 1,800 from Spain, 600 from France and 200 from Portugal — as well as 25 aircraft, such as Spain’s Eurofighter Typhoons, and six vessels including assault ships and a French mine hunter. “France was keen to be the...

Bit Milder Today, Terrific Thursday

Published Fri, 21 Feb 2025 21:38:02 GMT

While we’ve had a few spotty showers from time to time the last couple of days, we’ve also had many dry hours in the mix. Temps have also been fairly seasonable, running in the lower 60s. Overall, through 17 days in October, rainfall has been well below average for the month in Boston and Worcester with Boston only recorded .01″ or more on two days. Certainly the last couple of weeks have been a welcomed change in the pattern. Today, we’ll have a similar theme as yesterday with highs just a touch milder, low to mid 60s, and just a few isolated showers bubbling up. Overall, it’ll be a fairly quiet day. Tomorrow looks great, mostly sunny skies with temps in the mid to upper 60s as we’re dry from start to finish. Enjoy! Rain chances go up late Friday, Friday night and into Saturday as moisture rides in ahead of an area of low pressure. As that low crosses New England, it’ll strengthen and on the back side of it, provide us with gusty winds Sund...
