Quantum'Jamming' Could Help Unlock the Mysteries of Causality To keep communications secure in a post-quantum world, cryptographers are digging down into the concept of cause and effect. For the past few decades, researchers have understood that quantum computers should eventually be able to crack the widely used codes that secure much of the digital world. To protect against this fate, they've spent years developing new codes that appear to be safe from future safecrackers armed with quantum computers. At the same time, they've also devised ingenious ways to use the rules of quantum mechanics to keep communications secure. But quantum mechanics, just like the "classical" mechanics that preceded it, is just a theory of nature.

Zelenskyy says'time is right' for Ukraine to start process of joining EU Ukrainian President Volodymyr Zelenskyy has told European Union leaders that now is the time to begin the process of Ukraine's accession to the bloc, describing a proposal for associate membership as "unfair". Zelenskyy said in a letter to EU leaders on Friday that associate membership would leave Ukraine "voiceless" because it would not have voting rights, which would prevent Kyiv from advancing its interests, the Reuters news agency reported. Under Orban, who maintained close ties with Russia, Budapest repeatedly used its veto power to block Ukraine's accession bid and stalled approval of aid for Kyiv. Zelenskyy's push for EU membership comes as both Kyiv and Moscow seek to advance their interests on the battlefield. The head of the Russian-occupied Luhansk region in eastern Ukraine said on Saturday the death toll from a drone attack a day earlier had risen to 10. Vladimir Putin has ordered his forces to respond to the attack, which allegedly hit a student dormitory in the town of Starobilsk.

However, microbiologists say that boy kibble is a'recipe for disaster'.

The measure is part of a European Union-led strategy to eliminate all drunk-driving-related deaths and injuries by 2050. As of July 1, all vehicles sold within the European Union must include a standard, preinstalled interface that allows a breathalyzer lock to be added to the ignition system. This measure is part of a larger strategy promoted by the EU to reduce drunk-driving-related deaths and injuries by at least 50 percent by 2030. The requirement falls under the Vision Zero program, launched by European authorities more than five years ago, which aims to eliminate alcohol-related traffic fatalities entirely--or get as close to zero as possible--by 2050. The measure also aligns with the timetable established in the EU's General Safety Regulation, which sets specific deadlines for manufacturers to incorporate various safety features into vehicle designs, starting at the factory.

Chinese missiles and robots find warm welcome in EU's backyard Chinese leader Xi Jinping shakes hands with Serbian President Aleksandar Vucic at the Palace of Serbia during the Chinese president's two-day state visit to Belgrade in May 2024. If the European Union has a red line in Serbia's relationship to China, President Aleksandar Vucic may be getting close. The Balkan nation, the only European buyer of advanced Chinese weaponry west of Belarus, upgraded its arsenal this year to include supersonic missiles from China. Next may be fighter jets, a possible discussion topic when Vucic visits China next week. A Beijing bridgehead at the border of the EU has deepened doubts about the prospect of Belgrade joining the bloc and the limits of Vucic's strategy of juggling ties to the West, China and Russia.

A year to go until France chooses its next president, the big question is who can save the election from being a battle of the extremes. For now, and perhaps only for now, the answer is pretty clear. It is President Emmanuel Macron's former prime minister, Edouard Philippe. Latest opinion polls concur that the 55-year-old centre-right politician is the only figure capable of beating a hard-right candidate in round two of the vote next May, whether that is Marine Le Pen or her young deputy Jordan Bardella. In any other polled scenario, the other candidate would lose and France would have a populist-right head of state.

The Red Arrows will fly with fewer aircraft for most of their displays as the RAF seeks to preserve the famous aerobatics team's ageing fleet. Pilots will fly in a nine-aircraft formation for King Charles III's birthday flypast in June and one month later to help the US mark its 250th anniversary of independence but they will fly with seven aircraft for other events from this year. The current fleet of Hawk T1s - which have been flown by the Red Arrows since 1980 - is due to be retired in 2030, with spare parts less readily available. An RAF spokesperson said scaling back would support the sustainable management of the fleet and prepare the team for a transition to a future aircraft type. The Red Arrows are used to display the force's military capabilities and help with recruitment.

Russia's Putin vows retaliation after accusing Ukraine of hitting student dormitory Russian President Vladimir Putin has promised retaliation after accusing Ukraine of carrying out a deadly attack on a student dormitory in an occupied part of eastern Ukraine. Six people were killed and 39 injured in the overnight strike in the town of Starobilsk, Luhansk region, Putin said. Another 15 people were missing. Ukraine's military said it hit the headquarters of Russia's elite Rubicon drone military unit in Starobilsk. It did not say whether it was the same building as the one identified by Russia.

London Mayor Sir Sadiq Khan has been accused of putting politics over public safety after blocking a £50m contract between the Metropolitan Police and US tech firm Palantir. Scotland Yard had been in talks to use the company's artificial intelligence to speed up criminal investigations. Palantir's UK chief executive Louis Mosley also said the decision would give hostile states and criminals an advantage. The Met has previously warned it will have to cut officer numbers if the deal does not proceed. Palantir, founded by tech billionaire Peter Thiel, a prominent donor to US President Donald Trump, already holds contracts with other UK public sector bodies.
