Bacteria live in nearly every habitat on earth including within soil, water, acidic hot springs and even within our own guts. Many are involved in fundamental processes like fermentation, decomposition and nitrogen fixation. But scientists don’t understand a fundamental process within bacteria cells: how they organize themselves before division. Driving…

One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing it to a steady flow to measure its resistance in the form of drag. Studies on drag resistance have led to technological advances in…

Freshwater ecosystems account for half of global emissions of methane, a potent greenhouse gas that contributes to global warming. Rivers and streams, especially, are thought to emit a substantial amount of that methane, but the rates and patterns of these emissions at global scales remain largely undocumented. An international team…

CNN  —  The burned bodies of 18 people were found as wildfires ripped through Greece on Tuesday and countries across Europe sweltered under yet another extreme heat wave. The dead, found near a village in northern Greece, may have been migrants, the fire brigade said Tuesday. Another person was killed…

A new powerful antibiotic, isolated from bacteria that could not be studied before, seems capable to combat harmful bacteria and even multi-resistant ‘superbugs’. Named Clovibactin, the antibiotic appears to kill bacteria in an unusual way, making it more difficult for bacteria to develop any resistance against it. Researchers from Utrecht…

A few years ago while on a fishing trip in the Florida Keys, biologist Lori Schweikert came face to face with an unusual quick-change act. She reeled in a pointy-snouted reef fish called a hogfish and threw it onboard. But later when she went to put it in a cooler…

The Venus flytrap can survive in the nutrient-poor swamps of North and South Carolina because it compensates for the lack of nitrogen, phosphate and minerals by catching and eating small animals. It hunts with snap traps that have sensory hairs on them. If an insect touches these hairs two times,…

According to data from the Ministry of Land, Infrastructure and Transport, there were approximately 30,000 hydrogen-powered vehicles registered by 2022, representing a threefold increase compared to 2018. However, the country only has 135 hydrogen fueling stations. In order to enhance the accessibility of hydrogen-powered vehicles and establish hydrogen as a…

By increasing the diversity of indigenous plants in urban areas, researchers from the University of Melbourne have seen a seven times increase in the number of insect species in just three years, confirming the ecological benefits of urban greening projects. The findings are published in the British Ecological Society journal,…

Everyday symbols like &?!#@$ are highly memorable, according to new research. The new study led by the University of Waterloo aimed to investigate how well symbols are remembered compared to words with the same meaning. “Our work is ground-breaking as it highlights how humans remember graphic symbols and logos,” said…

‘Trimming’ the edge-states of a topological insulator yields a new class of material featuring unconventional ‘two way’ edge transport in a new theoretical study from Monash University, Australia. The new material, a topological crystalline insulator (TCI) forms a promising addition to the family of topological materials and significantly broadens the…

Australia’s iconic grass-trees — aka yaccas — are hardy, drought-tolerant, and strikingly beautiful. Now, new research has revealed another, far more important, feature: their ability to protect wildlife from deadly weather extremes. A study undertaken by the University of South Australia and Kangaroo Island Research Station shows that the yaccas’…

The diversity of family systems in prehistoric societies has always fascinated scientists. A groundbreaking study by Mainz anthropologists and an international team of archaeologists now provides new insights into the origins and genetic structure of prehistoric family communities. Researchers Jens Blöcher and Joachim Burger from Johannes Gutenberg University Mainz (JGU)…

Currently housed at the National Museum of Denmark, the clay brick originates from the palace of Neo-Assyrian king Ashurnasirpal II, in the ancient city of Kalhu. Known today as the North-West palace in Nimrud (modern-day northern Iraq), its construction began around 879 BCE. The brick has a cuneiform inscription (written…

Epoxy resins are tough and versatile polymers. In combination with glass or carbon fibers, they are used, for example, to manufacture components for aircraft, cars, trains, ships and wind turbines. Such epoxy-based fiber-reinforced polymers have excellent mechanical and thermal properties and are much lighter than metal. Their weakness: They are…

Household fruit and vegetable production, in allotments and gardens, could be key to a healthy and food-secure population, a new study from the University of Sheffield has found.
