Chile's resilient Patagonian Ice Dragon insect at risk from dwindling glaciers
CONCEPCION, Chile (Reuters) - Chile's Patagonian Ice Dragon is a tiny and mighty insect that lives its whole life in freezing glaciers while feeding off algae and bacteria.
The wingless finger-shaped black insect with long antennae measuring just 15 millimeters (0.6 inches) is one of the few creatures able to survive such harsh conditions, but it is now an endangered species as global warming accelerates the loss of glaciers.
Maribet Gamboa, a researcher at Chile's UCSC university, is leading a study that aims to preserve the Patagonian Dragon, as well as the glaciers it inhabits.
"The research aims to understand the glacier and understand how the Patagonian Dragon lives," Gamboa said, adding that scientists took samples from the insect to understand the genes that have adapted to its harsh climate.
First discovered in the 1950s, the Patagonian Dragon was believed to have been extinct until it was rediscovered during an expedition in 2001.
The mighty insect can survive up to 40 meters deep and is seen as an indicator of clean glacial waters since it acts as a natural filter, feeding on organic matter, dust and bacteria.
This, Gamboa hopes, will also let the insect become a barometer for glacier health in a warming world.
"It's a combination of studying the dragon and how climate change is affecting glaciers and its habitat," Gamboa said. "This lets us use it as a sentry for climate change in the region."

Russia says it tests new laser defences against drones
MOSCOW (Reuters) -Russia said on Friday it had conducted large-scale tests of new laser-based systems to defend against drones. A government statement described the new technology as "promising" and said it had been tested against various types of drone in different weather conditions. It said the anti-drone lasers would become part of a "universal air defence system" that President Vladimir Putin said this week Russia needed to build. "The test results will be used to refine existing models and create systems capable of providing reliable protection against modern air attack weapons. Conducting tests allows us to move on to serial production and upscaling," the statement said. An accompanying video showed charred debris from a destroyed drone. Both sides have deployed drones on a huge scale in the Russia-Ukraine war, using them to spot and hit targets not only on the battlefield but way beyond the front lines. Ukrainian drones have frequently struck sites deep inside Russia such as oil depots, refineries and airfields, highlighting the need for Moscow to boost its defences. Earlier this month, Ukrainian drones smuggled close to air bases in trucks inflicted serious damage to Russia's long-range bomber fleet.

Who are the officials killed in the Israeli attack on Iran?
(NewsNation) — Israel launched an attack on Iran on Friday, which resulted in a major blow to Iran's military chain of command. The strikes targeted Iran's nuclear facilities, ballistic missile factories and military commanders to prevent Tehran from developing an atomic weapon, killing at least three top military leaders and six nuclear scientists. At least 20 senior Iranian commanders, including Aerospace Force Commander Amir Ali Hajizadeh, were killed in the strikes, two regional sources told Reuters. Here's what we know about those killed: Four other scientists killed in Friday's strikes are Abdolhamid Manouchehr, Ahmad Reza Zolfaghari, Amirhossein Feghi and Motalibizadeh.
