Published African penguins: Climate refugees from a distant past?



Imagine the view from the western coastline of southern Africa during the Last Glacial Maximum (LGM) over twenty thousand years ago: in the distance you would see at least fifteen large islands -- the largest 300 square kilometers in area -- swarming with hundreds of millions of marine birds and penguin colonies.
Published Quantum computer applied to chemistry



There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have now used a quantum computer to undertake calculations within a real-life case in chemistry.
Published Surface steers signals for next-gen networks



5G signals known as millimeter-wave carry enormous amounts of information but are very easy to block. A new device helps these signals get around obstacles posed by walls, furniture and people.
Published Scientists identify 2022 sea urchin killer



A team of researchers has identified a single-celled organism called a ciliate as the cause of a massive die-off event to a marine animal vital to coral reef health.
Published X-ray analysis sheds new light on prehistoric predator's last meal



We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.
Published A team creates 'quantum composites' for various electrical and optical innovations



A team has shown in the laboratory the unique and practical function of newly created materials, which they called quantum composites, that may advance electrical, optical, and computer technologies.
Published Swimming secrets of prehistoric reptiles unlocked by new study



The diverse swimming techniques of the ancient reptiles that ruled the Mesozoic seas have been revealed.
Published Scientists discover pristine deep-sea coral reefs in the Galápagos Marine Reserve



Scientists have discovered extensive, ancient deep-sea coral reefs within the Galápagos Marine Reserve (GMR) -- the first of their kind ever to be documented inside the marine protected area (MPA) since it was established in 1998. The first reef observed was found at 400-600m (1,310-1,970 feet) depth at the summit of a previously unmapped seamount in the central part of the archipelago and supports a breathtaking mix of deep marine life.
Published Coastal species persist on high seas on floating plastic debris



The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.
Published Less ice, fewer calling seals



For several years, a team of researchers used underwater microphones to listen for seals at the edge of the Antarctic. Their initial findings indicate that sea-ice retreat has had significant effects on the animals' behavior: when the ice disappears, areas normally full of vocalizations become very quiet.
Published Learning about what happens to ecology, evolution, and biodiversity in times of mass extinction



Studying mass extinction events from the past can build our understanding of how ecosystems and the communities of organisms within them respond. Researchers are looking to the Late Devonian mass extinction which happened around 370 million years ago to better understand how communities of organisms respond in times of great upheaval.
Published How skates learned to fly through water



Genes are not the only drivers of evolution. The iconic fins of skates are caused by changes in the non-coding genome and its three-dimensional structure, an international research team reports.
Published It's all in the wrist: Energy-efficient robot hand learns how not to drop the ball



Researchers have designed a low-cost, energy-efficient robotic hand that can grasp a range of objects -- and not drop them -- using just the movement of its wrist and the feeling in its 'skin'.
Published Pollution monitoring through precise detection of gold nanoparticles in woodlice



Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.
Published Jellyfish and fruit flies shed light on the origin of hunger regulation



To survive, all organisms must regulate their appetite. Hormones and small proteins called neuropeptides perform this process, stimulating feelings of hunger and fullness. When researchers noted the similarities between GAWamide, a neuropeptide that regulates feeding in the Cladonema jellyfish, and myoinhibitory peptide, a neuropeptide that regulates feeding in fruit flies, they decided to test whether they could exchange the two. Their success in doing so highlights the deep evolutionary origins of feeding regulation.
Published Fully recyclable printed electronics ditch toxic chemicals for water



Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.
Published AI-equipped eyeglasses read silent speech



Researchers have developed a silent-speech recognition interface that uses acoustic-sensing and artificial intelligence to continuously recognize up to 31 unvocalized commands, based on lip and mouth movements.
Published Technology advance paves way to more realistic 3D holograms for virtual reality and more



Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.
Published How to overcome noise in quantum computations



Scientists have made significant progress in quantum computing by deriving a formula that predicts the effects of environmental noise. This is crucial for designing and building quantum computers capable of working in our imperfect world.
Published Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease



Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.
