Published Lion with nine lives breaks record with longest swim in predator-infested waters
(via sciencedaily.com) Original source A record-breaking swim by two lion brothers across a predator-infested African river has been documented in a new study. The researchers say the 1km swim is another example of iconic wildlife species having to make tough decisions to find homes and mates in a human-dominated world.
Published Research reveals the most complete dinosaur discovered in the UK in a century
(via sciencedaily.com) Original source The most complete dinosaur discovered in the UK in the last 100 years, with a pubic hip bone the size of a 'dinner plate', has been described in a new article.
Published A breakthrough on the edge: One step closer to topological quantum computing
(via sciencedaily.com) Original source Researchers have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing.
Published Researchers listen to the hearts of bats in flight
(via sciencedaily.com) Original source Unique recordings show that bats can ramp up heart rate from 6 to 900 b.p.m within minutes.
Published Moving from the visible to the infrared: Developing high quality nanocrystals
(via sciencedaily.com) Original source Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.
Published First local extinction in the US due to sea level rise, study suggests
(via sciencedaily.com) Original source The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published Whale remains tracked to highlight sustainable disposal benefits
(via sciencedaily.com) Original source A new study highlights the sustainable, cultural and ecosystem benefits of offshore removal or decomposition of whale remains. The study tracked the remains of a humpback whale that was intercepted before washing up on the shoreline, then repositioned 30km offshore and fitted with a satellite tag that tracked its position as it drifted with the wind and currents for 6 days before falling to the seabed.
Published Groundbreaking study reveals oceanic seabirds chase tropical cyclones
(via sciencedaily.com) Original source A new study reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life.
Published Cracking open a tasty menu for captive marsupials to sink their teeth into
(via sciencedaily.com) Original source From sifting through topsoil for native truffles to cracking open hard shells of seeds and nuts to munch on the tasty kernels, Australia bettongs and potoroos are described as 'ecosystem engineers' in a two-way relationship between their rich diet and environmental health. However, with native ecosystems and potoroid marsupial numbers in decline, ecology and evolution experts are working to understand how difficult it is to bite into the foods these leading foragers seek out.
Published Ancient large kangaroo moved mainly on four legs, according to new research
(via sciencedaily.com) Original source A type of extinct kangaroo that lived during the Pleistocene around two and a half million to ten thousand years ago, known as the 'giant wallaby', was a poor hopper, a study has found.
Published Life underground suited newly discovered dinosaur fine
(via sciencedaily.com) Original source A newly discovered ancestor of Thescelosaurus shows evidence that these animals spent at least part of their time in underground burrows. The new species contributes to a fuller understanding of life during the mid-Cretaceous -- both above and below ground.
Published New way for beneficial microbes to survive extreme conditions and space exploration
(via sciencedaily.com) Original source Investigators sought to help figure out how to send materials like probiotics into space and to better treat a variety of gastrointestinal (GI) and metabolic diseases. The team's formulations allow microbial therapeutics, including those used to treat gastrointestinal diseases and improve crop production, to maintain their potency and function over time despite extreme temperatures.
Published A 2D device for quantum cooling
(via sciencedaily.com) Original source Engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, which require extremely low temperatures to function optimally.
Published A genetic algorithm for phononic crystals
(via sciencedaily.com) Original source Researchers tested phononic nanomaterials designed with an automated genetic algorithm that responded to light pulses with controlled vibrations. This work may help in the development of next-generation sensors and computer devices.
Published Blue and great tits deploy surprisingly powerful memories to find food
(via sciencedaily.com) Original source Blue and great tits recall what they have eaten in the past, where they found the food and when they found it, a new study shows. In the first experiment of its kind to involve wild animals, blue and great tits demonstrated 'episodic-like' memory to cope with changes in food availability when foraging. The same study may suggest that humans leaving out seeds and nuts for garden birds could be contributing to the evolution of these memory traits.
Published Giant salamander-like creature was a top predator in the ice age before the dinosaurs
(via sciencedaily.com) Original source Meet Gaiasia jennyae, the swamp creature with a toilet seat-shaped head. It lived 40 million years before the first dinosaurs, and it was the top predator in its ecosystem.
Published Two new species of Psilocybe mushrooms discovered in southern Africa
(via sciencedaily.com) Original source In a new paper, researchers and citizen mycologists describe the two new species as Psilocybe ingeli and Psilocybe maluti. The paper also contains information on the traditional use of P. maluti by Basotho traditional healers from the mountain kingdom of Lesotho. According to the researchers, this appears to be the only recorded first-hand report of hallucinogenic mushrooms being used traditionally in Africa.
Published Giant clams may hold the answers to making solar energy more efficient
(via sciencedaily.com) Original source Solar panel and biorefinery designers could learn a thing or two from iridescent giant clams living near tropical coral reefs, according to a new study. This is because giant clams have precise geometries -- dynamic, vertical columns of photosynthetic receptors covered by a thin, light-scattering layer -- that may just make them the most efficient solar energy systems on Earth.
Published A new breakthrough in understanding regeneration in a marine worm
(via sciencedaily.com) Original source The sea worm Platynereis dumerilii is only a few centimeters long but has a remarkable ability: in just a few days, it can regenerate entire parts of its body after an injury or amputation. By focusing more specifically on the mechanisms at play in the regeneration of this worm's tail, a research team has observed that gut cells play a role in the regeneration of the intestine as well as other tissues such as muscle and epidermis.
Published Neutrons on classically inexplicable paths
(via sciencedaily.com) Original source Is nature really as strange as quantum theory says -- or are there simpler explanations? New neutron measurements prove: It doesn't work without the strange properties of quantum theory.
