Published Key building block for life found at Saturn's moon Enceladus
(via sciencedaily.com) Original source The search for extraterrestrial life in our solar system just got more exciting. A team of scientists has discovered new evidence that the subsurface ocean of Saturn's moon Enceladus contains a key building block for life. The team directly detected phosphorus in the form of phosphates originating from the moon's ice-covered global ocean using data from NASA's Cassini mission. Cassini explored Saturn and its system of rings and moons for over 13 years.
Published First illustration of the molecular machinery that makes cilia beat
(via sciencedaily.com) Original source The first image of the structures that power human cilia -- the tiny, hairlike projections that line our airways -- has now been produced and it could lead to much-needed treatments for people with rare cilial diseases.
Published Study explains unusual deformation in Earth's largest continental rift
(via sciencedaily.com) Original source Computer models confirm that the African Superplume is responsible for the unusual deformations, as well as rift-parallel seismic anisotropy observed beneath the East African Rift System.
Published Hotter sand from microplastics could affect sea turtle development
(via sciencedaily.com) Original source New research has found that extreme concentrations of microplastics could increase the temperature of beach sand enough to threaten the development of incubating sea turtles.
Published Scientists investigate the evolution of animal developmental mechanisms, show how some of Earth's earliest animals evolved
(via sciencedaily.com) Original source Lacking bones, brains, and even a complete gut, the body plans of simple animals like sea anemones appear to have little in common with humans and their vertebrate kin. Nevertheless, new research shows that appearances can be deceiving, and that a common genetic toolkit can be deployed in different ways to drive embryological development to produce very different adult body plans. It is well established that sea anemones, corals, and their jellyfish relatives shared a common ancestor with humans that plied the Earth's ancient oceans over 600 million years ago. A new study from the Gibson Lab, published in Current Biology on June 13, 2023, illuminates the genetic basis for body plan development in the starlet sea anemone, Nematostella vectensis. This new knowledge paints a vivid picture of how some of the earliest animals on earth progressed from egg to embryo to adult.
Published First side-necked turtle ever discovered in UK
(via sciencedaily.com) Original source The first side-necked turtle ever to be found in the UK has been discovered by an amateur fossil collector and palaeontologists.
Published New method traces ancestry of hybrid plants and animals
(via sciencedaily.com) Original source Hybrid plants and animals have complicated genomes. A biologist has discovered a way to reveal their parent species.
Published Aluminium-ion batteries with improved storage capacity
(via sciencedaily.com) Original source Scientists develop positive electrode material using an organic redox polymer based on phenothiazine. Aluminium-ion batteries containing this material stored an unprecedented 167 milliampere hours per gram, outperforming batteries using graphite as electrode material. Aluminium-ion batteries are considered a promising alternative to conventional batteries that use scarce raw materials such as lithium.
Published Pass the salt: This space rock holds clues as to how Earth got its water
(via sciencedaily.com) Original source The discovery of tiny salt grains in a sample from an asteroid provides strong evidence that liquid water may be more common in the solar system than previously thought.
Published Skipping evolution: Some kangaroos didn't hop
(via sciencedaily.com) Original source Extinct kangaroos used alternative methods to their famous hop according to comprehensive analysis.
Published DESI early data release holds nearly two million objects
(via sciencedaily.com) Original source The first batch of data from the Dark Energy Spectroscopic Instrument is now available for researchers to explore. Taken during the experiment's 'survey validation' phase, the data include distant galaxies and quasars as well as stars in our own Milky Way.
Published Marine environment at risk due to ship emissions
(via sciencedaily.com) Original source Researchers used four different types of port environments to investigate the levels of contaminants emitted from five different sources. They found that the combined emissions of metals and environmentally hazardous substances is putting the marine environment at risk. Ninety per cent of the harmful emissions came from ships fitted with scrubbers, whose purpose is to clean their exhaust gases.
Published The latest weapon against cancer is ... a keto diet?
(via sciencedaily.com) Original source Keto diets shrink pancreatic and colorectal tumors by starving them of the glucose they need to survive. But they also speed up development of a lethal wasting disease called cachexia. In mice, researchers have found that pairing keto with a corticosteroid prevents cachexia and increases survival.
Published Plant remediation effects on petroleum contamination
(via sciencedaily.com) Original source Initial choices about fertilization and grass seeding could have a long-lasting effect on how plants and their associated microbes break down pollution in petroleum-contaminated soils.
Published A step toward safe and reliable autopilots for flying
(via sciencedaily.com) Original source Researchers developed a machine-learning technique that can autonomously drive a car or fly a plane through a very difficult 'stabilize-avoid' scenario, in which the vehicle must stabilize its trajectory to arrive at and stay within some goal region, while avoiding obstacles.
Published Four-legged robot traverses tricky terrains thanks to improved 3D vision
(via sciencedaily.com) Original source Researchers have developed a new model that trains four-legged robots to see more clearly in 3D. The advance enabled a robot to autonomously cross challenging terrain with ease -- including stairs, rocky ground and gap-filled paths -- while clearing obstacles in its way.
Published The chatbot will see you now
(via sciencedaily.com) Original source Results from a study of the use of a chatbot in the consent process show that it encourages inclusivity, and leads to faster completion and high levels of understanding. Whereas the traditional method of consenting does not have a mechanism to verify understanding objectively, the chat-based method can test comprehension. It does not allow users who do not show understanding to give consent; rather, it puts them in touch with a genetic counsellor to figure out why knowledge transmission did not occur. It could be accessed at any time; more than half the patients interacted with the bot during these times, and this shows its utility in decreasing the barriers to entry to trials.
Published CRISPR/Cas9-based gene drive could suppress agricultural pests
(via sciencedaily.com) Original source Researchers have now used a gene-drive system to suppress an important agricultural pest.
Published Breakthrough in glioblastoma treatment with the help of a virus
(via sciencedaily.com) Original source Researchers are describing the results of a recent clinical trial -- a breakthrough in glioblastoma treatment with the help of a modified cold virus injected directly into the tumor. When combined with an immunotherapy drug, the authors observed a subset of patients that appeared to be living longer as a result of this therapy.
Published A baking soda solution for clean hydrogen storage
(via sciencedaily.com) Original source Scientists investigate the promising properties of a common, Earth-abundant salt.
