Hidden bird species discovered in Japan after DNA reveals a stunning secret
Hidden bird species discovered in Japan after DNA reveals a stunning secret
A bird long thought to be a single rare species in Japan has turned out to be two. Scientists discovered that the elusive Ijima’s Leaf Warbler and a newly identified Tokara Leaf Warbler look almost identical, but their DNA and songs reveal they are distinct species. The finding m
Discovery of enzymes that control pores on leaf surfaces could lead to drought-resistant c
A research team at the Ruhr University Bochum Department of Molecular and Cellular Botany, led by Professor Christopher Grefen, has uncovered how plants form the tiny pores on their leaves responsible for gas exchange and water regulation. The scientists identified the two lipid-

Artificial 'leaf' powers wireless biomedical device
Plants convert light into energy efficiently through photosynthesis—an ability that scientists and engineers still struggle to match with electronic devices. Recently, researchers have looked beyond traditional semiconductor materials to create devices using a promising class of
The 'water-saving' effect of vegetation under rising CO₂ may be overestimated
The 'water-saving' effect of vegetation under rising CO₂ may be overestimated
Climate warming is intensifying terrestrial water scarcity and drought risks worldwide. Meanwhile, rising atmospheric CO2 reduces plant stomatal conductance—the openness of leaf pores that governs both CO2 intake and water loss—and improves water-use efficiency, which has been wi
Far-red radiation and elevated CO₂ boost biomass accumulation in young leaf lettuce indoor
Far-red radiation and elevated CO₂ boost biomass accumulation in young leaf lettuce indoor
A new study from scientists at Purdue University reports that far-red radiation, in combination with increased carbon dioxide (CO₂) concentration, significantly enhances biomass production in young leaf lettuce grown under controlled environments, offering practical guidance for
Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water transport or whether browning leaves are a consequence o

Country diary: Our pond is a year old – already dragonflies are emerging | Nic Wilson
Hitchin, Hertfordshire: The broad-bodied chaser is often the first to arrive at a new pond, and sure enough, I spot an exuvia clinging to a leaf bladeThe hole in the nest box on our house wall is all mouth. A sparrow chick on the cusp of fledging has thrust its head out, beak ope
Simple treatment strengthens pineapple leaf fibers for sustainable composites
Simple treatment strengthens pineapple leaf fibers for sustainable composites
Pineapple leaf fiber has long been valued in parts of Southeast Asia for traditional uses, including basketry in Malaysia and Thailand and textile applications in the Philippines. Its high cellulose content and ready availability as an agricultural residue have also made it attra
Mouse found near 7,000 meters may rewrite limits of mammal survival
A tiny mouse living nearly 7,000 meters (23,000 feet) above sea level in the Andes is helping scientists rethink the limits of life on Earth. The animal, a leaf-eared mouse, is the focus of a new international study co-authored by McMaster University researchers, revealing how ma
