David Attenborough’s voice returns to British screens in ‘Secret Garden’, a BBC One series launched to celebrate the network’s 100th birthday. Unlike his classic wildlife documentaries, the show turns the lens toward the UK’s own backyards, exploring how gardens can rival tropical rainforests in biodiversity.Series producer Bill Markham explains that the programme deliberately avoids the usual “lions and tigers” spectacle, aiming instead for a relatable, garden‑centred narrative. He notes that British gardens collectively cover more area than all national nature reserves combined, and that an average garden can host up to 2,600 different species.The series tackles the contentious issue of domestic cats. With 9.5 million pet cats in Britain, Attenborough reveals they may kill around 55 million birds each year. Simple measures—such as fitting cats with bells—can slash hunting success by one‑third, while raising bird feeders reduces fatalities further.Markham stresses that the current predator‑prey balance is “unfair on the prey”, noting that cats are “the biggest predator in our gardens” yet are constantly fed, leading to an unsustainable population. He cites ecologist Dr Davide Dominoni, who suggests that keeping cats indoors during the breeding months of April and May could dramatically lower bird deaths.Beyond cats, the series examines other garden‑linked wildlife challenges. Each year, over 30 million pheasants—an Asian species—are released into the countryside, where they prey on native insects, reptiles, and amphibians. Markham argues that despite the countryside lobby’s claim that pheasant shooting sustains rural jobs, the practice “mess‑es with the ecology”.‘Secret Garden’ also showcases rare footage, including a pine marten hunting sand martins, an otter preying on ducks, and intricate mayfly battles reminiscent of the famed “snakes vs. iguana” scene from Planet Earth II. These moments underline the hidden drama unfolding in everyday green spaces.Markham hopes the series will soothe the growing eco‑anxiety many feel about climate change. He points out that the UK boasts roughly 25 million gardens, with 80 % of the population having access. Simple actions—like planting a native tree to boost caterpillar supplies for birds—can make a measurable difference.While the show may provoke cat owners and countryside advocates, Markham believes the nation’s love for “animals, gardens and David Attenborough” will drive a collective re‑thinking of garden stewardship. As Attenborough reflects, his first encounter with nature likely occurred in his own garden, setting him on the path to becoming the world’s most renowned naturalist.‘Secret Garden’ airs from 5 April on BBC One and iPlayer.

The Bank of England's initiative to feature nature on future banknotes has sparked a call to include flora and fungi in the designs, rather than just animals. This would better represent the natural world and highlight the crucial role these species play in sustaining life.The article in The Guardian notes that plants and fungi form the essential fabric of ecosystems, shaping landscapes, sustaining animals, birds, and insects, and supporting environmental health. By featuring them on banknotes, the Bank of England can bring attention to their immense value and inspire a deeper public appreciation for the living systems that sustain us.Nicola Hutchinson, Chief Executive of Plantlife International, emphasizes that celebrating plants and fungi on banknotes would recognize their vital importance and promote a greater understanding of the natural world. This move would be a significant step towards acknowledging the often-overlooked foundations of ecosystems.

The reintroduction of beavers in Dorset has shown promising results, with the animals building a 35-metre dam and creating a deep, wildlife-rich pool. By coppicing trees, they have allowed more light in and improved habitats for plants, insects, amphibians, birds, and bats.Trail cameras have captured footage of an otter fishing in the pond, as well as a barn owl hunting there. Volunteers have spotted birds including redpolls and water rails. The cameras also captured footage of two of the beavers mating, indicating they have settled in their new home and that there could be kits this summer.Despite some hitches, including the death of a male beaver and the relocation of a female, the western pair of beavers has been busy doing their engineering work. The National Trust, which is in charge of the project, said it was thrilled with the progress, highlighting the astonishing effect on the ecosystem in a relatively short time.Gen Crisford, the National Trust's wetlands project officer, said setbacks were inevitable but expressed hope for a 'happy ever after moment' with the western pair. The project allows for the release of 10 to 25 adult beavers, with the next release expected to take place this autumn.

A garden log pile is a surprisingly vibrant ecosystem, teeming with life. The pile, composed of various tree species like apple, walnut, and oak, attracts a diverse range of insects and fungi. The diversity of logs supports a greater variety of life, with different species inhabiting different parts of the pile.The log pile is home to frogs, wrens, and other animals, and even supports the growth of fungi like jelly ear. The arrangement of the wood also plays a crucial role in attracting different species, with buried wood attracting stag beetles and wood at height attracting wasp beetles.The author of the article, Kate Bradbury, carefully dismantles the log pile to make room for a hedgehog box, uncovering a variety of creatures like beetles, springtails, and centipedes in the process. The log pile is then rebuilt, with softer logs on the soil and drier ones around the box, creating a new home for a female hedgehog and other animals.

Researchers at Cortical Labs in Melbourne have created a 'biological computer' using living human tissue, which can play the 1993 shooter game Doom. The team used 10ml of blood from CEO Hon Weng Chong to harvest 100 white blood cells, which were then reprogrammed into induced pluripotent stem cells (iPSCs). These cells were used to create a dish of 200,000 neurons that can interface with a computer system.The brain cells were taught to play Doom by encoding game state information, passing it through a neural network, and converting it into signals the neurons can understand. The neurons then fire an output, which the system decodes and converts back into actions in the game. This process is similar to how humans operate, with information going into the retina, being converted into electrical signals, processed in the brain, and resulting in an output.While the achievement has sparked concerns about sentience and consciousness, Chong believes the brain cells are not conscious, stating, 'At first it didn’t know how to move, aim or shoot. Then it would shoot two enemies and stop. So it’s definitely learning.' The next step could be integrating this technology with Neuralink, a brain-machine interface developed by Elon Musk.The application of biological computing lies not in gaming, but in medicine, such as disease modeling for conditions like epilepsy. This technology could allow for personalized drug testing and tailored treatments. Meanwhile, Eon Systems in San Francisco has created a virtual insect brain that can behave like a real fly, challenging the assumption that intelligence must be acquired.Biological systems like these could eventually power robots, drones, and other machines that need to navigate complex environments. As Chong notes, 'Abstract reasoning, mathematics and language are relatively recent in evolutionary terms... but motor control and probabilistic decision-making are things we’ve inherited through millions of years of evolution.' While we're far from uploading human consciousness into the internet, this technology marks a significant step in the development of biological computing.
