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.

Google has issued a warning that quantum computers could potentially break most existing encryption systems by 2029, posing a significant threat to current cryptographic standards. The tech giant is urging banks, governments, and technology providers to prepare for this emerging threat.In a blog post, Google stated that the encryption currently used to keep information confidential and secure could easily be broken by a large-scale quantum computer in the coming years. The company, owned by Alphabet, emphasized the need for post-quantum cryptography migration to protect sensitive data.While quantum computers are still a nascent technology, Google, Microsoft, and universities across the UK and the US are actively building systems that harness the physics of quantum mechanics to perform extremely sophisticated mathematical calculations. However, constructing a powerful quantum computer with hundreds of thousands or even millions of stable qubits remains a significant technological challenge.Leonie Mueck, formerly the chief product officer of Riverlane, a Cambridge-based quantum startup, noted that Google's statement does not necessarily mean a working quantum computer capable of breaking encryption will definitely exist by 2029. Most timelines for a cryptographically relevant quantum computer range from the 2030s to the 2050s.Despite this, governments and organizations are already preparing for the eventuality that data stored to today's encryption standards would be exposed when the technology sufficiently advances. The UK's cybersecurity agency, the National Cyber Security Centre, has urged organizations to guard their systems against quantum hackers by 2035.Google's timeline suggests that engineering teams across the technology industry should consider measures to protect sensitive data by migrating to more advanced encryption systems now. Certain kinds of attacks predicated on the future availability of quantum decryption – “store now, decrypt later” – may currently be being deployed across the field.

Handel's mid-career novelty, Imeneo, is a comedy of duty and desire that defies conventions. Unlike Mozart's Così fan tutte, Imeneo eschews cynicism and cruelty, instead opting for a lighthearted, meta-theatrical approach.Director Guido Martin-Brandis and the Cambridge Handel Opera Company bring this operetta to life with a delightful staging that captures its knowing, self-referential charm. The set design, featuring a row of Ionic columns and an 18th-century fantasy of topiary and trellis, perfectly complements the opera's playful nature.The story follows Imeneo (played by Timothy Nelson), who rescues the city's marriageable young virgins from pirate-kidnappers. The conflict revolves around Rosmene (played by Ellie Neate), who must choose between gratitude and fidelity. Handel's music, conducted by Julian Perkins from the harpsichord, is a precise cocktail of artifice and sincerity, beautifully balanced by the cast.The cast delivers outstanding performances, with Neate's Rosmene growing in power throughout the final scene, and Lisa Dafydd's Clomiri captivating audiences with her sweet singing. Bethany Horak-Hallett's mezzo and Nelson's baritone are evenly matched, while Trevor Eliot Bowes brings comic relief as the patriarch Argenio.This production of Imeneo is a must-see, with its witty and careful handling of Handel's music and libretto. Don't miss it, running until March 28.

The UK government has unveiled plans for seven new towns in England, a move hailed as the most ambitious housebuilding project in the country for over 50 years. These new towns will feature between 15,000 to 40,000 homes each and are designed to be built with coordinated infrastructure, including schools, healthcare facilities, public transport links, and walking and cycling paths. The locations of the new towns include under-developed inner-city land, a historic village, and an existing new town. Notably, up to 40,000 homes are planned around the Bedfordshire village of Tempsford, near the A1, on a former RAF base. This new town will also feature a major station interchange, linking the east coast mainline with a new east-west link between Cambridge and Oxford. Five of the projects are situated within or on the edges of major cities, including two in London. These include: Crews Hill and Chase Park in Enfield, on the northern edge of London, with up to 21,000 homes. Thamesmead in south-east London, with 15,000 homes, supported by an extension of the Docklands Light Railway. Victoria North in Manchester, with about 15,000 homes. Leeds South Bank, with a planned 20,000 homes. Brabazon and the West Innovation Arc in the north of Bristol, with 40,000 homes. The final project involves 40,000 new homes in Milton Keynes, a city created from Buckinghamshire farmland and villages as one of the second-generation post-war new towns. Housing Secretary Steve Reed emphasized that the plan marks a significant shift in how the UK builds for the future, with communities designed from the ground up to include homes, jobs, transport links, and green spaces.
