A pair of cotton pants is not usually considered scientific equipment. Yet across Switzerland, thousands of them spent weeks underground as part of an unusual experiment into the condition of the soil beneath people’s feet.More than 1,000 volunteers took part, burying underwear and teabags at sites ranging from private gardens and farmland to grasslands and…
Image Credit: Left/The Wire/Right/CNN A cockroach producing something resembling milk sounds like an unlikely subject for serious scientific research. Yet one species has developed a remarkably unusual way of nourishing its young. The Pacific beetle cockroach, Diploptera punctata, gives birth to live offspring rather than laying eggs, and its developing young feed on a milk-like…
Harvard neuroscientists have kept tiny clusters of human brain cells alive in laboratory dishes for more than five years, setting a new record that could change how researchers study the human brain. The peppercorn-sized brain organoids, each containing more than one million cells from the cerebral cortex, survived for roughly three times as long as…
With countries fighting wars and natural calamities sweeping away civilisations, it seems a global collapse might be a spark away. But the possibility of entire humanity vanishing off the face of Earth seems a little less plausible with the years of effort we have spent preparing solutions for such situations. However, not everyone can be…
The Burmese python has become a symbol of two completely different conservation battles. In Florida, wildlife managers search for and remove the giant snake because its introduced population is threatening native wildlife in the Everglades. Thousands of kilometres away in Bangladesh, researchers are putting radio transmitters on the same species to understand where it moves,…
PC: Harris & Ewing/Wikipedia In 1921, a 14-year-old boy working in an Idaho potato field imagined something almost impossible: sending pictures through the air in the same way radio carried sound. His name was Philo Farnsworth, and the vision he had would eventually lead him towards electronic television. Farnsworth believed pictures could be transmitted as…
One of the world’s most difficult plastics to recycle could soon have a far more valuable second life. Scientists at Virginia Tech have developed a chemical method that converts polyvinyl chloride, or PVC, into polyalphaolefin, an important material used in high-performance lubricants including engine oil. The approach tackles a longstanding problem with PVC, which is…
Pine martens are making a remarkable return to south-west England after disappearing from Exmoor for more than a century, with conservationists capturing the first confirmed evidence that the reintroduced animals are breeding in the wild. A remote trail camera recorded a female pine marten with four kits on Exmoor, signalling that an ambitious effort to…
damselflyRepresenative image from Canva For much of the 20th century, the Santa Cruz River that winds through Tucson, Arizona, existed more as a memory than a living waterway. Groundwater pumping, drought and urban growth drained the riverbed, leaving long stretches of dry sand and scattered pools. Then, in a quiet but transformative experiment, treated wastewater,…
Centuries after people forced a Cumbrian river into a straight, artificial channel, nature has reclaimed its original course in the Lake District, bringing endangered wild fish back to historic spawning grounds almost immediately. In the summer of 2016, conservationists restored a 1.1-kilometre stretch of Swindale Beck near Haweswater by putting its natural bends back into…
