The LeadRoman Mars, the creator of the popular podcast 99% Invisible, is launching a new podcast called A History of the United States in 100 Objects, a sequel to the series A History of the World in 100 Objects that aired on Radio 4 in 2010. The Event DetailsMars's new series, co-produced by BBC Studios, SiriusXM, and 99% Invisible, comprises 100 episodes airing across two years, each highlighting objects and designs that tell the broader story of the United States. The podcast aims to explore American history through unusual items, such as the screw thread, the Bundy Clock, a gold coin recovered from the SS Central America, and the Billy Possum. The Data AnalysisMars has been researching the series for months, reading multiple books at once and listening to audiobooks at double speed while walking his dog. He believes that the experience has been akin to "putting myself through an American Studies major". The Impact AnalysisThe podcast is timed to coincide with the 250th anniversary of the US Declaration of Independence. Mars hopes to approach American history from a different perspective, using design as a lens to look at certain objects and ask what they say about America. The PredictionMars believes that his broadcasting career would not have taken off without the rise of podcasting. He notes that his voice is not a good fit for traditional radio, which prefers a clear and clipped tone. However, he has found his voice and become very relaxed behind the microphone, and he prefers to be the voice in listeners' heads rather than on video.

The Global Significance of the Fitzroy RiverThe Martuwarra Fitzroy River, which flows 700km through the Kimberley to King Sound, is considered the last stronghold for sawfish globally and is home to four of the world's five species. This untamed river ecosystem supports largetooth, dwarf, green and narrow sawfish, all protected under national environment laws. The river, its estuary and near-shore marine environment provide a critical habitat that represents what a relatively untouched sawfish population looks like on a global scale.The Water Extraction PlanA Western Australian government proposal aims to increase groundwater allocation from about 32GL to 75.7GL in the Fitzroy River catchment. While the draft water plan, now out for consultation, has proposed no additional surface water allocations and no dams on the river, environmental groups are particularly concerned about the increased groundwater extraction. The underground water stores feed several large pools and wetlands that act as crucial refuges for sawfish and other species during long dry periods.The Ecological ImpactEndangered largetooth sawfish, the largest and most imperilled species, are born at the river's mouth and spend several years inhabiting the river, its tributaries and deep aquifer-fed pools before heading out to sea. Adults can reach up to seven metres in size. Conservationists warn that sawfish won't survive without these refuge pools, which also provide life support for barramundi, a whole range of other fish, freshwater prawns and big trees and vegetation that sustain birds, possums, bats and insects.The Indigenous PerspectiveDr Anne Poelina, executive chair of the Martuwarra Fitzroy River Council, an alliance of elders and young leaders from traditional owners of the catchment, emphasized that water is precious and a life force. She stated that the lived experience of Aboriginal people on country is that the river is already stressed, and continued decline will affect people's lives and livelihoods as well as the environment, including access to clean drinking water and the rising cost of living. Poelina called for more time to gather information before any additional licences are granted.The Scientific ConcernDr Leonardo Guida from the Australian Marine Conservation Society described sawfish as "probably one of the most unique looking animals on the planet." Martin Pritchard from Environs Kimberley noted that the underground water stores that feed refuge pools are "absolutely critical in a landscape that's so hot and dry." Dr Ryan Vogwill, a hydrogeologist, explained that groundwater plays an "incredibly important" role supporting the high biodiversity and cultural values of the river ecosystem during dry periods when surface water isn't flowing.Future OutlookThe WA government's draft water plan requires applicants seeking a licence to demonstrate "sustainable groundwater use" and "protect water-dependent ecosystems and sites of ecological, cultural and social significance." However, conservationists remain concerned about the potential impacts, especially given the failure of a similar water allocation plan in the Pilbara where groundwater aquifers are in decline. The Fitzroy River has national and Aboriginal heritage list status for its outstanding cultural and natural values, making its protection a matter of significant environmental and cultural importance.

Executive Summary: A Nest That Paused a SaleA robin family chose the tire of a Ford F-250 at Olathe Ford Lincoln as a nesting site, invoking the Migratory Bird Treaty Act and legally barring the new owner from driving the vehicle off the lot.Robin Nest Halts Delivery of Ford F-250 in OlatheDealership staff discovered the nest in early May and posted about it on 14 May. The birds laid four blue eggs, which hatched within weeks. The dealership thanked customers for their patience and highlighted guidance from Operation Wildlife, a local rehabilitation nonprofit.Numbers Behind the Nest: Eggs, Hatchlings, and TimelineFour eggs laid on the tire.Eggs hatched within a few days, producing four fledglings.Discovery announced on 14 May via a Facebook post.Dealership reported additional wildlife (cats, opossums) in other vehicles.How the Migratory Bird Treaty Act Stalls Automotive TransactionsThe 1918 law protects nesting birds from disturbance, meaning any vehicle housing an active nest cannot be moved until the birds have fledged. This legal requirement forced the dealership to keep the truck on the lot, turning a routine sale into a viral story that drew national attention.Future Outlook: Compliance and Creative Marketing for DealershipsDealerships may need to develop standard protocols for wildlife encounters, including rapid consultation with wildlife experts. The Olathe team’s playful video series (naming the birds Lugnut, Turbo, Diesel, and Axel) shows how such incidents can be leveraged for positive brand exposure while respecting federal protections.

The Threat to Regent HoneyeatersResearchers have discovered that brush-tailed possums are occasionally raiding the nests of critically endangered regent honeyeaters, increasing their risk of extinction. Uncovering the Impact of Possum RaidsBianca McBryde, a researcher at the University of Sydney, set up 40 artificial nests in trees at North Head in Sydney. Over two weeks, possums raided only four of the nests, but this infrequent raid could have a significant impact on the honeyeaters' prospects for survival.The Data AnalysisMcBryde's research found that the loss of just a few eggs to the opportunistic possums could increase the risk of extinction within 20 years by about 35%. The Conservation ChallengeRegent honeyeaters are one of Australia's most threatened birds, with fewer than 250 likely left in the wild, restricted to three sites on the periphery of the Blue Mountains, to the west of Sydney. The birds' woodland habitats have been largely lost to developments and farming.The Future of ConservationThe research highlights the importance of understanding the impact of possum raids on regent honeyeater populations. By studying these interactions, researchers can develop more effective conservation strategies to protect this unique Australian bird.

In a fascinating collection of wildlife discoveries, a flying rodent has captured attention, alongside a duty-free possum and an emerald viper. These unusual finds have been highlighted in The Guardian's weekly wildlife roundup.The flying rodent, known for its unique abilities, has sparked interest among wildlife enthusiasts. Meanwhile, the duty-free possum and the emerald viper have also made headlines due to their distinct characteristics and the circumstances of their discovery.
