Cambridge University is launching a four-week summer course in botany, inspired by a course taught by Prof John Stevens Henslow to Charles Darwin in the 1820s. The course will use original teaching materials, including plant specimens and illustrations, to teach students about botany.The course aims to address the gap in botany education in the UK, where the subject has largely disappeared as a standalone degree. Dr Raphaella Hull, acting head of learning for Cambridge University Botanic Garden, said that the course will teach students about botany using hands-on techniques and field excursions.The course is based on Henslow's pioneering approach to teaching botany, which emphasized the importance of observing and understanding plant diversity. Henslow's use of illustrations on his course was groundbreaking, and he is credited with influencing Darwin's later theory of evolution.Prof Sam Brockington, curator of Cambridge University Botanic Garden, said that the course is designed to be an immersive program in botany, and that Henslow's approach to teaching botany is still relevant today.

The UK is on the brink of a medicine shortage crisis, with experts warning that the country is just weeks away from feeling the effects of the ongoing conflict in Iran. The war has already disrupted the supply of essential raw materials, including oil, gas, crop fertiliser, and helium.The pharmaceutical industry, which relies heavily on imports, is particularly vulnerable to these disruptions. India, known as the 'pharmacy of the world', produces a significant proportion of generic drugs and active pharmaceutical ingredients (APIs) used globally. However, with the Strait of Hormuz largely closed due to the conflict, the transportation of these vital supplies is becoming increasingly difficult.Medicine prices are also expected to rise as a result of the conflict. The US-Israel war on Iran has doubled air freight costs, which could make some medicines loss-making to supply to the NHS. While suppliers have long-term pricing agreements with NHS hospitals, they have more flexibility to increase prices for drugs supplied to GP practices and pharmacies.The UK's reliance on imported medicines is significant, with about half of its medicines produced domestically, a third coming from India, and another chunk from the EU. During the Covid pandemic, paracetamol and other painkillers were in short supply in Britain and elsewhere, as drugmakers in India struggled to keep up with demand.Medical distributors typically stock six to eight weeks of supplies to avoid shortfalls, but if the conflict drags on, drug shortages could emerge in only a few weeks' time. Experts warn that the overall ripple effect on the industry is significant, with the patient ultimately picking up the tab, either directly or via public health systems like the NHS.

The Reykjavik Open, a prestigious nine-round chess tournament commencing at the Harpa Conference Centre, carries significant historical weight as it takes place near the site of the legendary 1972 Bobby Fischer versus Boris Spassky match. First established in 1964 with Mikhail Tal as the inaugural winner, this year's event has attracted a substantial field of 422 players.The top seed is Iran's Amin Tabatabaei, the sole 2700-rated competitor in the tournament, followed by Romania's Bogdan-Daniel Deac (2655) and veteran Ukrainian Vasyl Ivanchuk (2654) as the fourth seed. England has dispatched a contingent of over 20 players, though most are amateur competitors. Grandmaster Matthew Wadsworth (2522) is seeded 21st, while Grandmaster Simon Williams (2443) holds the 39th position. Notably, 11-year-old Women's International Master Bodhana Sivanandan is pursuing her second Women's Grandmaster norm.In the opening rounds, the English trio secured victories, including Williams' impressive 20-move triumph. Sivanandan drew against a 2484-rated Chinese International Master in the second round.For the author, any chess event in Reykjavik evokes memories of 1973, when Fischer was anticipated to return to competitive play following his victory over Spassky. The author recounts an ambitious plan to organize a match involving Fischer, which included a two-game match against British champion William Hartston and an eight-board simultaneous exhibition against England's junior players. Despite personal connections to Fischer—including participation in a BBC-recorded consultation game in 1960—the proposed event never materialized after a negative response from Fischer's representatives.The author speculates that had the match occurred, it would have significantly advanced English chess, with Fischer likely prevailing 6-2 to 7-1 against the promising English juniors who would later achieve grandmaster status.The article concludes with a chess puzzle solution for position 4017, demonstrating the tactical complexity that characterizes high-level chess competition.

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.

A light-up C-3PO head used in Star Wars: Episode V – The Empire Strikes Back has fetched more than $1 million at an auction. The prop was part of a collection of film and TV memorabilia that went under the hammer on Wednesday as part of the Spring Entertainment Memorabilia Live Auction at Propstore auction house in Los Angeles.It is the only known example of the fictional droid’s head to appear on the collector market and sold for $1,058,400 (£790,440 or A$1,519,259), having received a pre-sale estimate of $350,000 to $700,000.The C-3PO head was the top lot at the auction, which also saw the harpoon gun used by the actor Robert Shaw in Jaws, accompanied by its original case, fetch $327,600.Elsewhere, a Wilson volleyball used by Tom Hanks in 2000’s Cast Away sold for $189,000 after receiving a pre-sale estimate of $150,000 to $300,000.The auction also featured broken pieces of a sword used in The Lord Of The Rings, which sold for $252,000.The first day of the auction fetched $6.5 million and also included items such as a golden ticket from the 1971 film Willy Wonka & the Chocolate Factory.Brandon Alinger, Propstore’s chief operating officer, said: “We’ve seen a strong start to the auction, with competitive bidding right from the outset.“At Propstore, Star Wars material continues to resonate with collectors and the C-3PO head from The Empire Strikes Back was a real highlight of the day.“The Jaws collection also delivered an impressive overall result, coming just after the film’s 50th anniversary and reflecting its enduring appeal with collectors.“With such a diverse lineup of material still to come, we’re excited to see how the rest of the auction unfolds.”The final day of bidding, 27 March, will be dedicated to animation, with more than 200 lots celebrating the artistry of animation in film and television.

The US-Israel war on Iran has effectively closed the Strait of Hormuz, a critical shipping route for materials used in the production of various everyday products. As the conflict enters its fifth week, global oil shortages are forcing countries to take severe measures to conserve their reserves. While US gas prices have surged to their highest level in years, the impact of rising oil prices extends far beyond drivers. Oil is a crucial component in the supply chain, powering machines that manufacture goods and fueling trucks that transport them to stores. The price increases come at a time when many Americans are already strained by rising housing costs, grocery bills, and electricity statements. A recent Gallup poll found that a third of Americans have had to skip meals and forego other needs to afford their healthcare. Oil and Gas The average cost of gas in the US has jumped about 30% over the last month, with the national average hitting $3.97, the highest since 2023. Diesel, which fuels many trucks transporting goods, has increased by about 50%, or $1.69 more than it did a year ago. Higher diesel costs could soon affect transportation costs and grocery prices, as roughly 85% of agricultural goods are transported by trucks. The impact of oil and gas shortages on the supply chain can be categorized as first-order effects, such as higher prices at the gas pump, and second-order effects, including potential price increases for crops, semiconductor chips, and medical devices. Fertilizer Farmers are struggling as the spring growing season approaches, facing higher fertilizer costs and falling commodity prices. A third of global urea trade, a solid nitrogen fertilizer, passes through the Middle East region, with about 20% of imported fertilizer to the US coming from Qatar. Nitrogen fertilizer is critical to grow corn, which is cultivated by about 500,000 farmers in the US. The White House has promised to minimize disruptions to the US economy, with alternative sources of fertilizer being sought from around the world. Helium The conflict has disrupted the global helium supply after Iranian attacks in Qatar, the second-largest producer of helium after the United States. Helium is a key import used in aerospace, magnetic resonance imaging (MRI), and semiconductor chips that power AI. Jet Fuel Increases in oil prices could result in higher airfare and shipping costs. The price of jet fuel has doubled since the start of the war, according to the International Air Transport Association. United Airlines announced last Friday that it would have to cut flights due to the surging cost of fuel. < h2>Mortgage Rates Just as US mortgages were starting to fall in February, the average 30-year fixed mortgage rate ticked up to its highest level in months, reaching 6.22%. Mortgage rates are closely tied to the overall state of the economy, and the US Federal Reserve's decision to leave rates unchanged last week cited uncertainty in the economy, particularly with conflict in the Middle East.

Retailer Next has reported a £1.16bn pre-tax profit for the full year, with the Middle East conflict expected to add only £15m to fuel and air freight costs. This amount, which assumes a three-month disruption, is considered minimal and can be offset by savings elsewhere.Chief Executive Simon Wolfson added £8m to this year's profit forecast as a mechanical read-through from last year's outcome, indicating that trading had been “encouraging” in the UK and “strong” overseas until late February.The main concern for Next is the potential long-term impact of the conflict on supply chain resilience, freight rates, factory gate prices, and consumer demand. Wolfson emphasized that the company has no insight into the duration and implications of the conflict, stating, “As yet, we have no feel for the medium-term effects”.If higher costs persist, Next may put up prices, but this remains “a contingency, not a plan”. The company will provide a clearer view in its first-quarter update in May.Wolfson also offered nuanced insights, suggesting that consumer confidence may not have collapsed as much as some, like the British Retail Consortium, have claimed. He noted that UK consumers tend to react to actual higher prices, not the threat of them.Additionally, Next's spring-summer ranges are already in stores, online, and warehouses, minimizing the immediate need for adjustments. Any increases in fabric costs or production disruptions in Asian factories would mostly affect autumn-winter ranges.The stock market responded positively, with Next's shares rising 5% to £125.40. This resilience could indicate potential for a profit upgrade in May if the £15m in extra costs turns out to be the worst of it.However, no retailer will be immune if the energy price shock persists and the OECD's prediction of UK economic growth of just 0.7% this year materializes.

The UK government's recent announcement to make significant cuts to direct aid to Africa and the Middle East has been met with deep disappointment. This move is seen as a moral dereliction of duty, betraying the world's most marginalised, and a false economy that will bring greater instability to the world and make people less safe. The cut in aid to 0.3% of gross national income (GNI) from 2027 breaks Labour's 2024 manifesto pledge to restore development spending at the level of 0.7% of GNI “as soon as fiscal circumstances allow”. The UK is making the steepest proportion of aid cuts among G7 nations. As James Mattis, Donald Trump's defence secretary, once said: “If you don’t fund the state department fully, then I need to buy more ammunition ultimately.” This highlights the shortsightedness of cutting aid, which could lead to more conflict, famine, and persecution. The UK itself benefits materially from these investments. The recent inquiry by the all-party parliamentary group on global health and security on international health worker recruitment highlights the extent to which the NHS and wider economy rely on the skills, expertise, and partnerships rooted in the global south. The UK has saved £14bn in training costs through international recruitment and continues to depend on globally trained health professionals. Investment in global vaccination, disease surveillance, and research helps stop outbreaks before they spread internationally and place pressure on health systems. Preventing disease at source is one of the smartest investments we can make to protect patients in Britain. The situation in Somalia, on the edge of famine, underscores the importance of sustained investment in global development. Two consecutive failed rainy seasons have left 6.5 million people in crisis, more than double the number a year ago. The UK's humanitarian relief in Somalia is welcome, but the scrapping of nature funding and cuts to climate aid risk compromising its own strategy of preventing crisis before it takes hold.
