Published Neuroptera: Greater insect diversity in the Cretaceous period
(via sciencedaily.com) Original source An LMU team has studied the biodiversity of larvae from the insect order neuroptera over the past 100 million years.
Published Newly sequenced hornet genomes could help explain invasion success
(via sciencedaily.com) Original source The genomes of two hornet species, the European hornet and the Asian hornet (or yellow-legged hornet) have been sequenced.
Published ChatGPT is still no match for humans when it comes to accounting
(via sciencedaily.com) Original source ChatGPT faced off against students on accounting assessments. Students scored an overall average of 76.7%, compared to ChatGPT's score of 47.4%. On a 11.3% of questions, ChatGPT scored higher than the student average, doing particularly well on AIS and auditing. But the AI bot did worse on tax, financial, and managerial assessments, possibly because ChatGPT struggled with the mathematical processes required for the latter type.
Published Evolution of two contagious cancers affecting Tasmanian devils underlines unpredictability of disease threat
(via sciencedaily.com) Original source Evolution of two contagious cancers affecting Tasmanian devils underlines unpredictability of disease threat. Scientists have traced the family trees of two transmissible cancers that affect Tasmanian devils and have pinpointed mutations which may drive growth of deadly diseases.
Published Two qudits fully entangled
(via sciencedaily.com) Original source Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.
Published Swimming secrets of prehistoric reptiles unlocked by new study
(via sciencedaily.com) Original source The diverse swimming techniques of the ancient reptiles that ruled the Mesozoic seas have been revealed.
Published Team designs four-legged robotic system that can walk a balance beam
(via sciencedaily.com) Original source Researchers have designed a system that makes an off-the-shelf quadruped robot nimble enough to walk a narrow balance beam -- a feat that is likely the first of its kind.
Published A neuromorphic visual sensor can recognize moving objects and predict their path
(via sciencedaily.com) Original source The new smart sensor uses embedded information to detect motion in a single video frame.
Published How can a pollinating insect be recognized in the fossil record?
(via sciencedaily.com) Original source Insect pollination is a decisive process for the survival and evolution of angiosperm (flowering) plants and, to a lesser extent, gymnosperms (without visible flower or fruit). There is a growing interest in studies on the origins of the relationship between insects and plants, especially in the current context of the progressive decline of pollinating insects on a global scale and its impact on food production. Pollinating insects can be recognized in the fossil record, although to date, there has been no protocol for their differentiation. Fossil pollinators have been found in both rock and amber deposits, and it is in rock deposits that the first evidence of plant pollination by insects is being studied across the globe. But how can we determine which was a true insect pollinator in the past?
Published Tracking a new path to octopus and squid sensing capabilities
(via sciencedaily.com) Original source Research has traced the evolutionary adaptations of octopus and squid sensing capabilities. The researchers describe for the first time the structure of an octopus chemotactile receptor, which octopus arms use for taste-by-touch exploration of the seafloor.
Published Multi-compartment membranes for multicellular robots: Everybody needs some body
(via sciencedaily.com) Original source We typically think of robots as metal objects, filled with motors and circuits. But the field of molecular robotics is starting to change that. Like the formation of complex living organisms, molecular robots derive their form and functionality from assembled molecules stored in a single unit, i.e., a body. Yet manufacturing this body at the microscopic level is an engineering nightmare. Now, a team has created a simple workaround.
Published Software to untangle genetic factors linked to shared characteristics among different species
(via sciencedaily.com) Original source Scientists have developed a software package to help answer key questions about genetic factors associated with shared characteristics among different species.
Published Study reveals how pollinators cope with plant toxins
(via sciencedaily.com) Original source Pollinators such as honeybees produce special enzymes that detoxify defence chemicals produced by plants, new research shows.
Published Biologists determine the evolutionary age of individual cell types providing critical insights for animal development
(via sciencedaily.com) Original source A research team has recently made a significant discovery about the evolutionary age of different type of cells in a small animal called Caenorhabditis elegans (C. elegans). By using single-cell transcriptomic data and refined phylostratigraphy, the team determines the transcriptomic age of individual cells, which means they are able to estimate the evolutionary origin of different cells based on the age of the genes expressed in the cells.
Published Oldest bat skeletons ever found described from Wyoming fossils
(via sciencedaily.com) Original source Scientists have described a new species of bat based on the oldest bat skeletons ever recovered. The study on the extinct bat, which lived in Wyoming about 52 million years ago, supports the idea that bats diversified rapidly on multiple continents during this time.
Published Research in Japan shows the way toward tactile and proximity sensing in large soft robots
(via sciencedaily.com) Original source To make human-robot interactions safer and more fruitful, robots should be capable of sensing their environment. In a recent study, researchers developed a novel robotic link with tactile and proximity sensing capabilities. Additionally, they created a simulation and learning framework that can be employed to train the robotic link to sense its environment. Their findings will pave the way to a future where humans and robots can operate harmoniously in close proximity.
Published Study compares de novo proteins with randomly produced proteins
(via sciencedaily.com) Original source In a series of experiments, a team of researchers have compared de novo proteins with random-sequence proteins, looking at their stability and solubility. The results are set to advance basic research in this new field.
Published How skates learned to fly through water
(via sciencedaily.com) Original source 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 Scientists track evolution of microbes on the skin's surface
(via sciencedaily.com) Original source Researchers have discovered that Staphylococcus aureus can rapidly evolve within a single person's microbiome. They found that in people with eczema, S. aureus tends to evolve to a variant with a mutation in a specific gene that helps it grow faster on the skin.
Published British flower study reveals surprise about plants' sex life
(via sciencedaily.com) Original source A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces. When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.
