May 12, 2025 A team of researchers investigated a sequence of coastal dunes of different ages (from 0-700,000 years old) in Cooloola National Park near Rainbow Beach to understand how soil microorganisms coped with severely declining levels of nutrients such as phosphorus in soil as the dunes got older. They found microbes -- such as fungi and bacteria -- ...

May 13, 2025 Researchers have identified a never-before-seen mechanism that enables HIV-1 to evade the body's natural defenses and use it to support its survival and replication. The 'loophole' is a biological process that involves circular RNAs and marks the first experimental evidence of HIV-1 generating them from an integrated retroviral genome. Findings point to a novel strategy the virus uses to survive, ...

May 12, 2025 Stifling heat and sticky air often make summertime in the city uncomfortable. Due to the heat island effect, urban areas are significantly warmer than nearby rural areas, even at night. This, combined with more frequent extreme weather events caused by climate change, often render the city an unpleasant environment in the summer. Urbanization and climate change modify the thermal environment of ...

May 13, 2025 Butterflies' flight trajectories often appear random or chaotic, but their hovering patterns can potentially provide critical design insights for developing micro aerial vehicles with flapping wings. Researchers studied how butterflies use aerodynamic force generation to achieve hovering, using high-speed cameras to observe wild-caught white ...

May 12, 2025 Current methods of capturing and releasing carbon are expensive and so energy-intensive they often require, counterproductively, the use of fossil fuels. Taking inspiration from plants, researchers have assembled a chemical process that can power carbon capture with an energy source that's abundant, clean and free: ...

May 12, 2025 Pink salmon, Purple Asian clams, marine invertebrates that form spaghetti-like colonies and a nematode worm that causes extensive deaths of trees are among the new entries in experts' watchlist of invasive non-native species that could threaten Great Britain in the next 10 years. The latest version of the watchlist again includes known problem ...

May 9, 2025 The Arctic landscape during the Cretaceous Period may have been dominated by the dinosaurs, but the rivers and streams held something more familiar. Alaska's fresh waters 73 million years ago were teeming with the ancient relatives of today's salmon, pike and other northern fish. A new article has named three new species of fish from that time period, including a salmonid, dubbed Sivulliusalmo ...

May 9, 2025 Scientists have discovered fossil evidence of an endangered, living tropical tree species. The unprecedented find was made in Brunei, a country on the large island of Borneo, and reveals a critical piece of the ancient history of Asia's rainforests, highlighting the urgent need for conservation in the region, according to ...

May 7, 2025 Life depends on genes being switched on and off at exactly the right time. Even the simplest living organisms do this, but usually over short distances across the DNA sequence, with the on/off switch typically right next to a gene. This basic form of genomic regulation is probably as old as life on Earth. A new study finds that the ability to control genes from far away, over many tens of ...
