Ukraine cyber-operators are being deployed on the front lines of the war, duelling close-up with their Russian counterparts in a new kind of high-tech battle. "We have people who are directly involved in combat," says Illia Vitiuk, the head of the Ukrainian Security Service's (SBU) cyber department. Speaking inside the heavily protected SBU headquarters, he explains how his teams mix the skills of hackers and special forces - getting inside Russian systems, working alongside snipers and deploying the latest technologies. The department uses Artificial Intelligence (AI) visual recognition systems to analyse information gathered from aerial drones (alongside intelligence from human sources, satellites and other technical sources) to provide targets for the military.

The aircraft was flying from Moscow to St Petersburg, with seven passengers and three crew. Everyone on board is reported to have died. The news led to widespread speculation that President Putin and Russian military leaders may have been responsible for Yevgeny Prigozhin’s death. A Telegram channel with links to the Wagner group said that Prigozhin had died “as a result of actions of traitors of Russia”. Prigozhin, whose Wagner forces had been fighting in support of Russia in Ukraine, led a failed mutiny against the Russian armed forces in June. At the time he moved his troops out of Ukraine, seizing the southern Russian city of Rostov on Don and threatening to march on Moscow. The uprising came after months of tension with Russian military commanders over the Ukraine conflict. At the time, Russia's President Putin accused Wagner of being “traitors”. The stand-off was settled by a deal which allowed Wagner troops to move to Belarus or join the regular Russian army. Prigozhin himself agreed to relocate to Belarus but was apparently able to move freely afterwards, making a number of public appearances. The plane crash came on the same day that the senior Russian general Sergei Surovikin was reportedly sacked as chief of the Russian air force. General Surovikin was known to have good relations with Prigozhin and had not been seen in public since the mutiny.

India has made history as its Moon mission becomes the first to land in the lunar south pole region. With this, India joins an elite club of countries to achieve a soft landing on the Moon, after the US, the former Soviet Union and China. The Vikram lander from Chandrayaan-3 successfully touched down as planned at 18:04 local time (12:34 GMT). Celebrations have broken out across the country, with Prime Minister Narendra Modi saying "India is now on the Moon".

Many assume that how we age comes down to genetics, but environmental factors play a major role. Professor Rose Anne Kenny explains the science behind living a longer, healthier life.

Russia's unmanned Luna-25 spacecraft has crashed into the Moon after spinning out of control. It was Russia's first Moon mission in almost 50 years. The craft was designed to be the first ever to land on the Moon's south pole, but failed after encountering problems as it moved into its pre-landing orbit. It was set to explore a part of the Moon which scientists think could hold frozen water and precious elements. Roscosmos, Russia's state space corporation, announced that it had lost contact with the Luna-25 and believed the craft had "ceased to exist as a result of a collision with the surface of the Moon”. The loss of Luna-25 is a blow to Roscosmos. Russia's civilian space programme has been in decline for several years, as state funding is increasingly directed towards the military.
