Here is a summary of current scientific news.

Tiny robots made in Mexico to explore the moon in scientific premiere

Five tiny robots designed and made in Mexico will blast off to the moon later this year, in a first-of-its-kind science mission that envisions two-wheeled robots hurtling across the lunar surface while taking sophisticated measurements. The so-called nano-robots developed by researchers at the National Autonomous University of Mexico (UNAM) will work together like a swarm of bees, the lead scientist told Reuters, once they travel nearly 240,000 miles (386,000 km) from Earth aboard a rocket from the American company Astrobotic Technology.

NASA ignores Roscosmos chief’s rant on US sanctions and space station

On Friday, NASA ignored public comments from the head of its Russian counterpart suggesting that US sanctions imposed on Moscow over the Ukraine crisis could “destroy” US-Russian teamwork on the International Space Station (ISS). Dmitry Rogozin, director general of Russia’s Roscosmos space agency, took to Twitter on Thursday to decry new constraints on high-tech exports to Russia that US President Joe Biden said were designed to “degrade their industry aerospace, including their space program”.

Hard-Headed, Tiny-Armed Dinosaur Fossil Found in Argentina

Scientists in Argentina have unearthed the remains of a previously unknown species of carnivorous dinosaur that lived around 70 million years ago that had weak arms and is said to have used its powerful head to ram its prey. The fossil skull of the Cretaceous dinosaur, named Guemesia ochoai, was discovered in the province of Salta, in the northwest of Argentina. The researchers said it likely belonged to a group of carnivorous dinosaurs called abelisaurs, which walked on two legs and had only butt-like arms, even shorter than those of Tyrannosaurus rex from North America.
