Five Guys' chief executive officer, Jerry Murrell, revealed that he gave a $1.5m bonus to employees of his US-based burger restaurant chain to make up for the chaos caused by a recent promotion. The buy-one-get-one-free offer, which was intended to celebrate the company's 40th anniversary, proved to be much more popular than expected, causing the chain's app to crash and many locations to become overwhelmed.Murrell stated that he gave the bonus because "I didn't want anybody shooting me in the back or anything … because we really screwed it up." The comment was made in an interview with Fortune, where he also joked that he preferred the employees receiving the bonus over his wife getting "a new fur coat."The promotion, which was launched in February, was initially met with intense criticism on social media, prompting Five Guys to apologize and restart the offer for four days. Murrell attributed the chaos to the company's underestimation of the promotion's popularity, stating that "we had no idea that we were going to get that kind of response."Five Guys currently operates 1,900 locations and employs 30,000 people in 28 countries worldwide. The company's CEO since its founding in 1986, Murrell has taken steps to address the backlash and improve customer satisfaction.

The notion of governments controlling prices has long been considered taboo in modern economics. However, with the resurgence of inflation and its far-reaching consequences, this stance is beginning to shift. Politicians are now exploring the possibility of intervening in the market to regulate prices, a move that would have been deemed unthinkable just a few decades ago.The Austrian economist Friedrich Hayek had argued that governments lacked the necessary information to make informed decisions about prices, leading to inefficiencies in state-run economies. Nevertheless, as market economies have struggled to provide affordable essentials like energy and housing, interest in state-regulated prices has begun to grow.Examples from Mexico and Spain demonstrate the effectiveness of government intervention in controlling prices. In Mexico, the left-wing president Andrés Manuel López Obrador and his successor Claudia Sheinbaum have capped the prices of essential goods, while in Spain, the centre-left government of Pedro Sánchez has implemented a national rent freeze and energy price cap.In the UK, Zack Polanski of the Green party has advocated for a wider price reset, while Andy Burnham, a possible Labour leadership candidate, has also called for more state involvement in the economy to reduce prices. Burnham's experiences as mayor of Greater Manchester, where he has brought buses back under public control, have informed his arguments.The pressure for the UK to adopt similar measures is mounting, with a majority of British voters supporting nationalizations to get prices under control. As inflation continues to rise, it remains to be seen whether the UK government will follow the example of countries like Spain and Mexico.

The UK government has introduced new guidelines aimed at helping parents manage their children's screen time. Children under five should spend no more than an hour a day on screens, according to the advice developed by a panel led by the children's commissioner, Rachel de Souza, and children's health expert Prof Russell Viner.For children under two, screen time should be avoided except for shared activities that encourage interaction. The guidance also suggests that bedtimes and mealtimes should be screen-free, with families encouraged to opt for background music, table games, bedtime stories, and colouring instead.Prime Minister Keir Starmer emphasized that the guidance will help families keep children safe and build healthy habits with screens. He stated, “Parenting in a digital world can feel relentless. Screens are everywhere, and the advice is often conflicting. My government will not leave parents to face this battle alone.”The panel's review found that long periods of solo screen time can harm sleep, physical activity, creative play, and interaction with parents, which are crucial for good development. About 98% of children watch screens daily by the age of two, and high screen time has been linked to impacts on language development.Prof Russell Viner noted, “Too much solo screen time can crowd out the things that make the biggest difference – sleep, play, physical activity and talking with parents and carers.” The guidance also recommends that parents consider their own screen use in front of their children and explore screen-free periods for the whole family.

UK Prime Minister Keir Starmer has pledged to take on social media companies in a bid to protect children from addiction, as new guidelines recommend limiting screen time for children under five to no more than an hour a day. The guidelines, developed by a panel led by the children's commissioner, Rachel de Souza, and children's health expert Prof Russell Viner, advise that children under two should avoid screen time except for shared activities. Ministers are also exploring Australia-style measures to limit or ban social media for under-16s, as part of a broader effort to regulate social media companies and protect children. Starmer emphasized that regulating social media companies will require a 'fight' to ensure they do not prioritize profits over children's well-being. 'Some of this will require a fight,' he said. 'If we're going to do more to protect children, we're going to have to fight some of the platforms that are putting the material up there because they're putting this addictive stuff up there for a reason.' The guidelines advise families to avoid fast-paced social media-style videos and toys or tools that use artificial intelligence for children aged two to five. They also recommend screen-free bedtimes and mealtimes, and encourage shared screen activities like video calling or looking through photos together. According to the government, about 98% of children watch screens daily by the age of two. Infants with high screen time are less likely to be read to or go on outdoor trips, which can impact language development. Experts have welcomed the guidelines, with Dr. Mike McKean, vice-president for policy at the Royal College of Paediatrics and Child Health, saying they will help parents protect 'short, but developmentally crucial early years.'

The ongoing conflict between the United States, Israel, and Iran has created a significant disruption in the global helium supply chain, affecting approximately one-third of worldwide production. This critical resource, essential for both medical diagnostics and advanced manufacturing, faces unprecedented challenges as shipping restrictions and production halts impact markets worldwide.The disruption stems primarily from Qatar, the world's largest helium producer, which accounts for about 63 million cubic meters of the roughly 190 million cubic meters of helium produced globally annually. Following Iranian attacks on Qatari energy infrastructure, QatarEnergy has announced a 14% annual reduction in helium exports, citing damage to its LNG facilities that also produce helium as a byproduct.The Strait of Hormuz, a critical maritime chokepoint, has seen traffic nearly grind to a halt after Iranian officials announced new transit restrictions. This waterway serves as the primary export route for Qatar's helium, with no viable alternative maritime outlet available.The impact of this helium shortage extends across multiple sectors. MRI machines, which rely on helium's unique cooling properties, face potential operational delays, while the semiconductor industry—a cornerstone of modern technology—also depends on this irreplaceable resource for chip manufacturing. South Korea, Japan, Taiwan, and China stand as the most vulnerable economies, being the largest consumers of Gulf-sourced helium.Market analysts project that helium prices could surge by 10-50% depending on the duration of the supply disruption, with buyers lacking long-term contracts experiencing the most immediate price increases. The medical industry, in particular, has been attempting to develop alternatives, including helium-free MRI technologies and helium recycling systems, though most current systems remain dependent on liquid helium.The United States, as the largest global helium producer at over 40% of worldwide supply, cannot fully compensate for the Gulf shortfall. Even North American consumers face challenges, with major distributors like Airgas already cutting shipments by half and parent company Air Liquide reallocating its supply chain to access helium from other regions.This helium crisis represents the fifth significant supply shortage since 2006, highlighting the vulnerability of global supply chains for critical industrial materials with no artificial substitutes. The situation underscores how geopolitical conflicts can have far-reaching consequences beyond traditional energy markets, potentially impacting healthcare accessibility and technological innovation worldwide.
