Eating alone, daily testing, no talking at mealtimes – the COVID rules recently announced for athletes competing in the Tokyo Olympic and Paralympic Games are challenging, to say the least. On top of the rules, there is the threat of deportation for failure to observe those rules. This only compounds the considerable stress that athletes have been seen to experience at previous Olympics, and risks affecting their motivation. As Japanese tennis player Kei Nishikori put it, it’s “not going to be fun for me … you don’t feel like playing the Olympics in your home country”. Much has been written about the fun that athletes had…

Cyberwarfare consists of co-ordinated attacks of mass disruption (AMD). In the June summit between U.S. and Russian presidents Joe Biden and Vladimir Putin, cyberwarfare was a topic of discussion. While the Biden-Putin summit appears to be “quite constructive,” cyberwarfare remains perplexing to politicians. Attacks of mass disruption are similar to the latest ransomware attacks on SolarWinds and Colonial Pipeline — imagine several co-ordinated similar attacks. For the time being, organizations should prepare for increasing disruptions and data losses caused by ransomware. Attacks of mass disruption may not cause massive casualties, but nations could lose their ability to function and respond to adversaries, economies…

On the morning of June 17, China launched its long-awaited Shenzhou-12 spacecraft, carrying three Chinese astronauts – or taikonauts – towards the Tianhe core module. The module itself was launched at the end of April, forming part of the permanent Tiangong space station, which is planned to remain in orbit for the next ten years. China’s construction of its own space station stems from the nation’s exclusion from the International Space Station, a result of US concerns over technology transfers that could enhance China’s military capabilities. Undeterred by this, China has forged ahead with its own space programmes and alliances. Since, the…

The headlines are filled with news about ransomware attacks tying up organizations large and small, data breaches at major brand-name companies and cyberattacks by shadowy hackers associated with Russia, China and North Korea. Are these threats to your personal information? If it’s a ransomware attack on a pipeline company, probably not. If it’s a hack by foreign agents of a government agency, maybe, particularly if you’re a government employee. If it’s a data breach at a credit bureau, social media company or major retailer, very likely. The bottom line is that your online data is not safe. Every week a new major data breach is reported, and most…

Fraud has reached “epidemic” levels in the UK over the past 12 months, costing up to £190 billion a year and constituting what the Royal United Services Institute has called a “national security threat” in need of an urgent institutional response. But it’s clear that the police are struggling to keep pace with fraudsters. A 2018 Which? report found that an estimated 96% of fraud cases reported to Action Fraud go unsolved. And with scams seemingly on the rise, 54% of which involve the internet, the problem of online fraud appears to be getting worse. There are romance scammers forming bogus online relationships with their victims, pet scammers setting up thousands…

Small aerial drones are touted as a disruptive technology, with massive investment and hype surrounding their use. They may deliver our morning coffee, pizzas, time-sensitive medical supplies and Amazon orders. These on-demand drone applications require a high proportion of uptime or flyability — the amount of time when drones can fly safely. But a key factor often overlooked in the hype about on-demand drone applications is the weather: drones cannot and should not fly in all types of weather. The weather conditions most likely to prevent drone use are precipitation (which can damage electronics), strong winds (which can increase battery usage or even cause drones to lose…

Have you ever chatted with a friend about buying a certain item and been targeted with an ad for that same item the next day? If so, you may have wondered whether your smartphone was “listening” to you. But is it really? Well, it’s no coincidence the item you’d been interested in was the same one you were targeted with. But that doesn’t mean your device is actually listening to your conversations — it doesn’t need to. There’s a good chance you’re already giving it all the information it needs. Can phones hear? Most of us regularly disclose our information to…

In their Carbis Bay communique, the G7 announced their intention to work together to tackle ransomware groups. Days later, US president Joe Biden met with Russian president Vladimir Putin, where an extradition process to bring Russian cybercriminals to justice in the US was discussed. Putin reportedly agreed in principle, but insisted that extradition be reciprocal. Time will tell if an extradition treaty can be reached. But if it is, who exactly should extradited – and what for? The problem for law enforcement is that ransomware – a form of malware used to steal organisations’ data and hold it to ransom – is a very slippery fish. Not only…

Failure of a machine in a factory can shut it down. Lost production can cost millions of dollars per day. Component failures can devastate factories, power plants and battlefield equipment. To return to operation, skilled technicians use all the tools in their kit – machining, bending, welding and surface treating, making just the right part as quickly and as accurately as possible. But there’s a declining number of technicians with the right skills, and the quality of things made by hand is subject to the skills and mood of the artisan on the day the part is made. Both problems could…

Last month, China successfully landed and deployed the Zhurong rover on Mars, becoming the second country ever to set wheels on the surface of the red planet. Last year the United States, the United Arab Emirates and China all launched missions to Mars, taking advantage of the relatively short journey time offered by the two planets’ unusually close proximity. Why are planetary scientists so obsessed with Mars? Why spend so much time and money on this one planet when there are at least seven others in our solar system, more than 200 moons, countless asteroids, and much more besides? Fortunately, we are going to…
