The quest to find Australia's oldest playable musical instrument has led to the discovery of several remarkable pieces. A 16th-century double bass crafted by Gasparo da Salò, a renowned luthier, has been found to be one of the oldest playable instruments in the country. Currently on loan to Max Bibeau, principal double bass for the Australian Chamber Orchestra (ACO), this instrument was made around 1580 in Brescia, Italy. Only a handful of such instruments exist globally, and Bibeau's relationship with the double bass was not immediate. He notes that it took considerable time and effort to 'wake it up' and make it playable again. The instrument had been stored in an abbey in northern Italy for centuries before being discovered by German bass player Prof Günter Klaus in the late 1960s. Culturally, the yidaki (didgeridoo), a sacred instrument to the Yolŋgu people, is likely Australia's oldest instrument, with a history spanning thousands of years. For an exhibition in 2017, curators at the South Australian Museum worked with Yolŋgu community members to restore a selection of the oldest and most unique yidaki to playing condition. The oldest restored yidaki was made around 1890. Another contender for the oldest instrument is a piano from the First Fleet, a 'square' piano made by Frederick Beck in 1780. This instrument, now housed at the Western Australian Academy of Performing Arts, has a softer and smaller sound compared to modern pianos. The oldest instrument found in Australia is an ocarina from Colombia, estimated to have been made around AD 1200. This ancient vessel flute is part of a collection of 830 musical instruments donated to the Queensland Museum. While it can produce a sound, its original sound and playability are uncertain due to its fragility and age. The wood used for the front of Bibeau's da Salò bass has been dated to a tree growing as early as 1266. According to Bibeau, age can enhance an instrument's sound, but it requires careful preservation and play to maintain its quality. He notes that 'instruments need to be played' and that 'the more it vibrates, the better it vibrates.'

In the face of rising fuel costs, Sydney commuters are increasingly turning to bicycles as a viable alternative for their daily commutes. This shift is reminiscent of Copenhagen's response to the 1970s global oil crisis, where the city dramatically expanded its bicycle network.Recent data shows a significant increase in cycling activity in Sydney. In March, there were 600,000 bike-sharing trips in the City of Sydney, a 25% increase from the previous month. Additionally, thousands of cars have disappeared from Sydney's roads, with car traffic falling by around 5% in March compared to the previous year on major arterial roads.The surge in cycling is also reflected in the sales of electric bikes. At 99 Bikes, ebike sales have surged by 136% year on year in the past week. Bike retailers are experiencing booming business, with many customers citing high petrol prices as the reason for purchasing a bicycle or ebike.According to Australian Automobile Association (AAA) data, in the last quarter of 2025, the average Australian household spent about $453 per week on car-running costs. With unleaded petrol prices peaking at almost 260c per litre in April, a 50% increase from last year, the financial incentive for switching to bicycles is clear.Experts see this trend as an opportunity for a green revolution in transportation. Peter McLean, the CEO of Bicycle NSW, suggests that governments should capitalize on the cycling boon by investing heavily in active transport infrastructure rather than relying on short-term fuel excises.

Article 52 of the first Additional Protocol to the Geneva Conventions bars attacks on civilian targets. The International Criminal Court has already issued arrest warrants for Russian officers involved in strikes on Ukraine’s energy grid, a precedent that would apply to the United States if President Donald Trump’s threats to bomb Iran were carried out. Trump, alongside Defense Secretary Pete Hegseth, has adopted a tone that resembles a “blood‑thirsty fever dream.” Hegseth framed the proposed Operation Epic Fury as a 21st‑century crusade, while Trump unleashed a profanity‑laden tirade demanding the immediate reopening of the Strait of Hormuz, warning that “Tuesday will be Power Plant Day, and Bridge Day… Open the Fuckin’ Strait, you crazy bastards, or you’ll be living in Hell.” This rhetoric, emerging just before the United States’ 250th independence anniversary, undermines the credibility of the presidency and the nation’s moral standing. The editorial notes that, in a more restrained political climate, senators like Chris Murphy might explore constitutional avenues to remove Trump, but the current cabinet’s “craven complicity” makes such prospects remote. The international community now watches anxiously, fearing that a broader escalation between the United States, Israel, and Iran could trigger “unknowable and spiralling consequences.” Iran has signaled it could widen its attacks across the region, and the recent closure of the Hormuz Strait demonstrates that Trump’s threats are not merely rhetorical. NATO allies have declined to endorse Trump’s approach, citing the absence of a coherent strategy and a lack of legal justification. They hope the president’s apocalyptic language masks a genuine search for a rapid de‑escalation, especially as global economic pressure mounts. Trump later claimed there was a “good chance” of a cease‑fire with Iran before his deadline, yet hours later Israel bombed a key petrochemical plant in Iran’s largest gas field, contradicting any notion of imminent peace. During a White House press briefing, Trump and Hegseth highlighted the rescue of a missing U.S. fighter crew shot down over Iran, a moment that starkly contrasted with the looming threat to thousands of lives and the stability of the global economy, now hanging on the whims of a president driven by self‑aggrandizement and an echo chamber of advisers.

The peptide-testing industry has seen a significant surge in demand, with laboratories testing thousands of unregulated substances claiming to support weight-loss and wellness. This growth is largely driven by the injectable peptide craze, with experts warning about the lack of reliable safety data and quality control.Peptides are short chains of amino acids, which can be found naturally in the body or made synthetically in laboratories. They include active ingredients in prescription weight-loss drugs, such as Wegovy, as well as experimental compounds pushed online by the booming biohacking and anti-ageing industries.Laboratories, such as Finnrick in Texas, have reported a substantial increase in testing requests, with around 60,000 samples processed annually, including roughly 2,000 orders from the UK since 2024. About a third of the products analysed failed basic quality checks, with issues including incorrect identity, purity, and quantity.Experts, including Dr. Luke Turnock and Peter Magic, have highlighted the risks associated with these unregulated substances, including potential long-term harms such as increased cancer risk and damage to organs. The large profit margins have also drawn nefarious actors into the supply chain.The UK is a significant market for peptides, with 2,000 testing orders since 2024, tied with Canada for third place globally. The Royal Pharmaceutical Society's Prof Amira Guirguis emphasized the need for oversight, traceability, and quality assurance in the peptide market.

Conservationists and scientists have warned that the Minerals Council of Australia’s proposal to employ artificial intelligence for faster national environmental approvals could generate “Robodebt‑style” failures, further endangering already vulnerable species.The council has asked the federal government to allocate $13 million for a pilot that would use AI to help companies draft assessment applications and assist regulators in decision‑making.The Biodiversity Council – a consortium of independent experts from eleven universities – told Guardian Australia that while AI may assist with routine tasks, automating whole environmental assessments could lead to opaque, flawed decisions that push threatened species closer to extinction.“Robodebt” refers to the automated welfare‑debt recovery scheme that, between 2015 and 2019, wrongly accused hundreds of thousands of Australians of overpayments, highlighting the danger of opaque algorithmic judgments.Lis Ashby, the Biodiversity Council’s lead on policy and innovation, noted that the cornerstone of Australia’s environmental protection, the Environment Protection and Biodiversity Conservation (EPBC) Act, is riddled with vague language and broad ministerial discretion, which hampers rule‑based decision‑making and would be even more problematic for an AI tool.She added that establishing clear rules in the National Environmental Standards, including explicit definitions of unacceptable outcomes, would accelerate assessment times even without AI and is essential for any future automation.Brendan Sydes, national biodiversity policy adviser at the Australian Conservation Foundation, expressed scepticism, stating that “technology can be a good servant but a poor master.” He urged the government to focus on closing existing data gaps on threatened species and habitats rather than relying on AI.Prof. David Lindenmayer, a forest ecologist at the Australian National University and Biodiversity Council member, highlighted that one‑third of Australia’s threatened species have not been monitored and many others suffer from patchy data, gaps traditionally filled by expert consultation.He warned that AI decisions are only as reliable as the data they are fed, and most threatened species lack publicly available information, even basic location data, risking decisions based on outdated or incomplete evidence.The Albanese government recently passed reforms to the EPBC Act after a 2020 review found the legislation failing to protect species and habitats.Prof. Hugh Possingham, a leading conservation biologist at the University of Queensland, argued that AI models need robust training material, and the past two decades of EPBC approvals are “clearly unsuitable” because the Act has demonstrably failed to safeguard the environment. He suggested that hiring more human assessors would be a more effective way to speed up evaluations.Tania Constable, chief executive of the Minerals Council, dismissed the Robodebt comparison as “disappointing,” insisting the proposal is innovative and could strengthen environmental protection while improving efficiency. She said the AI tools would support human decision‑making for both regulators and project proponents, helping navigate the complexity of EPBC assessments.A federal government spokesperson said budget decisions on the AI trial will be made “in due course,” but the environment department is exploring how AI could simplify application processes. The statement emphasized that “decisions about whether to approve projects must, and will, always be made by assessment officers, not by AI.”Nonetheless, officials acknowledged that AI tools have the potential to save time, reduce uncertainty, and translate technical language for stakeholders.

Donald Trump has repeatedly framed inflation as a "hoax" and declared that he has "won affordability," yet independent analyses reveal that his touted initiatives deliver only marginal relief for most Americans.One of his most publicized programs, the TrumpRX prescription‑drug platform, lists just 61 medications out of the thousands needed nationwide. Moreover, price comparisons show that a medium dose of Wegovy costs $349 on TrumpRX, while the same dose sells for $163 in Japan and $198 in Germany. Similar gaps appear for diabetes drug Xigduo and autoimmune medication Xeljanz, which are significantly cheaper abroad.The website markets itself as a solution for uninsured, cash‑paying patients, but it does nothing for the roughly 85 % of Americans who already have prescription coverage.On housing, Trump’s executive order banning Wall Street firms from buying single‑family homes is unlikely to move the needle. Institutional investors own only about 2 % of such homes, while the nation faces a shortage of roughly 4.7 million units, according to Zillow. The ongoing war in Iran has also pushed mortgage rates higher, further straining affordability.Gasoline prices have surged since the Iran conflict began, climbing to an average of $4.10 per gallon – a 37 % increase from the pre‑war level of $2.98.Food costs tell a similar story. The Consumer Price Index shows a 3.1 % rise in overall food prices from February 2025 to February 2026, with coffee up 18.4 %, beef up 14.4 %, and fresh vegetables up 5.4 %. Tariffs championed by the administration have contributed to these hikes.International bodies echo domestic concerns. The OECD projects U.S. inflation to exceed 4 % this year, largely driven by the Iran war, a level higher than the 3 % rate recorded at the end of the Biden administration.Trump also claims to have eliminated taxes on overtime and Social Security benefits. In reality, overtime earnings are still subject to federal income tax on the base wage and to full Social Security and Medicare payroll taxes. Only the overtime premium enjoys a partial tax break. Likewise, more than half of Social Security recipients will continue to owe income tax on their benefits, contradicting the administration’s “no‑tax” narrative.Other initiatives, such as the “Trump Accounts” child‑savings program, provide a one‑time $1,000 seed deposit and allow families to contribute up to $5,000 annually. While beneficial for affluent households, the scheme offers limited assistance to families living paycheck‑to‑paycheck.Policy decisions have also raised costs for vulnerable groups. By opposing extensions of Obamacare subsidies, average health‑care premiums have risen by over 20 % for more than 20 million people. Simultaneously, proposed cuts to LIHEAP threaten heating and cooling assistance for roughly 6 million low‑income households.In sum, Trump’s affordability rhetoric serves more as political branding than substantive economic relief. The modest scope of his programs and the persistence of rising prices suggest that most working‑class Americans will see little improvement in their day‑to‑day expenses.

Mayor Claudia Kalisch, vice‑president of the German Federation of Cities and leader of the Green‑party city of Lüneburg, announced a push for a nationwide ban on night‑time use of robotic lawnmowers. The proposal aims to curb injuries and deaths among hedgehogs and other small nocturnal animals that frequent residential gardens after dark.Recent research has highlighted that the fast‑moving blades of autonomous mowers pose a hidden danger to wildlife active between dusk and dawn. Hedgehogs, which often curl into a ball when threatened, are especially difficult for mower sensors to detect.Kalisch told the Funke newspaper group that urban green spaces have become critical refuges as development and intensive agriculture shrink natural habitats. She noted that petitions urging the ban have amassed tens of thousands of signatures earlier this year, reflecting broad public concern.In addition to legislative pressure, the mayor called on manufacturers to develop hedgehog‑friendly technology. She emphasized that industry responsibility is essential for protecting biodiversity and improving city life quality.The European red‑list classifies hedgehogs as "near threatened" since 2024, after a documented 30% population decline over the past decade. Beyond mower hazards, motorised leaf blowers, vacuums, and vehicle collisions—responsible for up to one in three fatalities—exacerbate the species’ decline across Europe.Scientists at the University of Oxford, in collaboration with Danish colleagues, recently demonstrated that hedgehogs can hear high‑frequency ultrasound, opening the possibility of sonic road repellers to deter them from dangerous areas. The same team has produced 3D‑printed, crash‑test dummy hedgehogs to work with manufacturers on a future certification scheme for "hedgehog‑safe" mowers.Study co‑author Anne Berger of Germany’s Leibniz Institute for Zoo and Wildlife Research warned that injuries from robotic mowers place an "enormous burden" on animal‑care centres, with many victims discovered days or weeks after the incident, enduring prolonged suffering.German law already protects hedgehogs, imposing fines of up to €65,000 for illegal trapping, injury, or killing. Several cities—including Cologne, Leipzig and Munich—have already outlawed night‑time mower operation. However, a recent attempt by the Greens to enact a statewide ban in Bavaria was rejected.

As the northern hemisphere welcomes spring, the constellation of Boötes, the herdsman, is rising to prominence in the eastern sky after dusk. This celestial display is a treat for stargazers, with the constellation's brightest star, Arcturus, shining brightly.A chart showing the view looking east from London at 21:00 BST on 6 April illustrates the optimal viewing conditions. By this time, the darkness is complete, and Arcturus, the fourth-brightest star in the night sky, is easily visible.To locate Boötes, start with the familiar shape of the Plough and follow the curve of its handle downwards in an arc until you reach the orange glow of Arcturus. This method makes it easy to find the constellation in the night sky.Boötes is one of the original 48 constellations defined by Ptolemy in the second century. However, its origins date back thousands of years to ancient Babylon, where it was associated with the god Enlil. In Greek tradition, Boötes is often identified as a herdsman or ploughman, with various mythic tales surrounding his role as a protector of rural life.During this time of year in the northern hemisphere, Boötes rises during twilight and becomes well-placed for observation by late evening. Conversely, from the southern hemisphere, Boötes appears low in the northern sky.

Thousands of independent UK businesses are preparing for heating‑oil expenses to more than double after the Iran war sent Europe’s fuel markets to fresh record highs.Roughly 7% of all small and medium‑sized enterprises (SMEs) heat their premises with oil, and in many rural locations the figure climbs to about 17%, according to the Federation of Small Businesses (FSB), which represents around 200,000 firms and sole traders.With many rural firms off the gas grid, they depend on heating oil—a kerosene derivative linked to jet‑fuel prices. Prices have surged dramatically: a supplier charged 54.9p per litre in January and demanded 129p per litre by late March, a rise of 116%. One hotel and restaurant owner in North Yorkshire, Anthony Jenkins, reported that his annual oil bill, normally around £3,000, is now unaffordable.Jenkins said he has cut fuel usage by half and is asking guests to lower radiator settings rather than open windows. He also hopes to shift to solar‑heated water as daylight hours increase.The FSB has urged the UK competition watchdog to extend its probe of the heating‑oil market to include SMEs, noting that the same shock has lifted North‑west European jet fuel to $1,900 per tonne and diesel to $1,600 per tonne, according to Argus.Trade bodies warn that the volatility creates a fertile environment for rogue energy brokers who may push small firms into unfavorable long‑term contracts. Tina McKenzie, policy chair of the FSB, stressed the need for stricter broker regulations, noting that many SMEs lack the bargaining power of larger corporations.Small businesses also miss out on the government’s household energy‑price cap and other consumer protections, despite their energy usage resembling that of households. McKenzie added that the market’s rapid evolution leaves many firms “nervous and vulnerable”.Proposals to tighten broker oversight, including tighter scrutiny by Ofgem, are pending new legislation. An Ofgem spokesperson said the regulator has reminded suppliers and brokers to “treat customers fairly, prioritize transparent pricing and good consumer outcomes”, acknowledging the “concerning volatility” caused by the Middle‑East conflict.
