Using NASA’s Perseverance rover, scientists are getting a greater understanding of the nature of some of the organic carbon — the molecular backbone for all known living organisms — detected on Mars as they explore the question of whether Earth’s planetary neighbor ever harbored life. New research describes the structure of the organic carbon found last year by the rover in sedimentary rock that contained a potential biosignature — a possible sign of past microbial life. This mudstone formed perhaps between 3.2 and 3.8 billion years ago beneath a now-vanished body of water in Jezero Crater in the Martian northern…

 Artificial intelligence is rapidly transforming the US economy, helping entrepreneurs build businesses more quickly while fueling debate over its long-term impact on jobs, productivity and economic growth.

Working from her home in Virginia Beach, Turner used AI to learn startup fundamentals, prepare a business plan and refine presentations for investors. The company has since grown to 16 employees and is…

A tanker traveling off the coast of Oman in the Strait of Hormuz caught on fire early Tuesday morning after being struck by a projectile, the British military said. The attack was the latest targeting a vessel moving through the narrow mouth of the Persian Gulf, through which a fifth of all oil and natural gas traded once passed in peacetime. Iranian state television said the liquefied natural gas tanker came under attack after ignoring warnings but did not directly claim the assault. Tehran has repeatedly declared that only its approved route through the strait is safe and is suspected…

US President Donald Trump said on Monday (Jul 6) the United States would either reach a deal with Iran or “finish the job,” renewing his threat of military action as Tehran projects defiance following the funeral of Supreme Leader Ayatollah Ali Khamenei. Indirect US-Iran talks ended last week without any public sign of headway toward a lasting peace, despite a 60-day ceasefire intended to create space for diplomacy following the US and Israeli strikes that triggered the conflict. “We’re either going to make a deal or we’re going to finish the job. OK. And it won’t be tough to finish…

NATO allies will showcase surging defence spending at a summit in Turkey’s capital Ankara on Tuesday as they hope to placate US President Donald Trump after his fury over Europe’s response to the war with Iran.

NATO chief Mark Rutte insists European countries are “delivering” on their promise by bolstering military budgets and moving to take more responsibility for the defence of their continent in the face of Russia.…

China on Tuesday marked the 89th anniversary of the Lugou Bridge Incident, also known as the July 7 Incident of 1937, which marked the start of the entire nation’s resistance against Japanese aggression during World War II. Following the incident in southwest Peiping (Beijing), the city was captured by the Japanese army on July 29, 1937. Over 10,000 civilians were killed or went missing during the fall of the city.
