Published Scientists grow 'mini kidneys,' revealing new insights into metabolic defects and potential therapy for polycystic kidney disease
(via sciencedaily.com) Original source Scientists have successfully grown 'mini kidneys' in the lab and grafted them into live mice, revealing new insights into the metabolic defects and a potential therapy for polycystic kidney disease.
Published Bringing multidrug-resistant pathogens to their knees
(via sciencedaily.com) Original source Multidrug-resistant bacterial infections that cannot be treated by any known antibiotics pose a serious global threat. A research team has now introduced a method for the development of novel antibiotics to fight resistant pathogens. The drugs are based on protein building blocks with fluorous lipid chains.
Published How mosquito larva guts could help create highly specific insecticides
(via sciencedaily.com) Original source Did you know that the world's deadliest animal is the mosquito? And Aedes aegypti is one of the most dangerous. This bug spreads viruses that cause dengue fever, which was recently declared as an epidemic in Puerto Rico. Research reports new molecules that label proteins in the unique, alkaline environment of the Ae. aegypti digestive system that could help scientists develop insecticides to fight back.
Published How the moon turned itself inside out
(via sciencedaily.com) Original source Linking analyses of the moon's gravity field with models of its earliest evolution, scientists tell a story of the moon turning itself inside out after it solidified from a primordial magma ocean. The process left behind a vestige of dense, titanium-rich material beneath its Earth-facing side that makes its presence known by gravity anomalies.
Published Climate change threatens Antarctic meteorites
(via sciencedaily.com) Original source Antarctica harbors a large concentration of meteorites imbuing the icy continent with an unparalleled wealth of information on our solar system. However, these precious meteorites are rapidly disappearing from the ice sheet surface due to global warming, according to a new study.
Published Telescope detects unprecedented behavior from nearby magnetar
(via sciencedaily.com) Original source Captured by cutting-edge radio telescope technology, a chance reactivation of a magnetar -- the Universe's most powerful magnets -- has revealed an unexpectedly complex environment.
Published Integrated dataset enables genes-to-ecosystems research
(via sciencedaily.com) Original source A new dataset bridging molecular information about the poplar tree microbiome to ecosystem-level processes has been released. The project aims to inform research regarding how natural systems function, their vulnerability to a changing climate, and ultimately how plants might be engineered for better performance as sources of bioenergy and natural carbon storage.
Published Can language models read the genome? This one decoded mRNA to make better vaccines
(via sciencedaily.com) Original source Researchers developed a foundational language model to decode mRNA sequences and optimize those sequences for vaccine development. The tool shows broader promise as a means for studying molecular biology.
Published eDNA methods give a real-time look at coral reef health
(via sciencedaily.com) Original source The study underscores the crucial role of microbes in maintaining coral reef health, akin to the human gut microbiome. Hurricanes and disease outbreaks affect coral reef water microbial communities, leading to changes that may support further reef decline. Microbial analysis enables prompt assessment of disturbances' impacts on coral reefs, facilitating timely interventions to support reef ecosystems. Environmental DNA (eDNA) analysis offers a noninvasive approach to study coral microbial communities and diagnose reef health.
Published Chemical reactions can scramble quantum information as well as black holes
(via sciencedaily.com) Original source A team of researchers has shown that molecules can be as formidable at scrambling quantum information as black holes by combining mathematical tools from black hole physics and chemical physics and testing their theory in chemical reactions.
Published Neutron stars are key to understanding elusive dark matter
(via sciencedaily.com) Original source Scientists may be one step closer to unlocking one of the great mysteries of the universe after calculating that neutron stars might hold a key to helping us understand elusive dark matter.
Published Rapid, simultaneous detection of multiple bacteria achieved with handheld sensor
(via sciencedaily.com) Original source A team has developed a method for simultaneous detection of multiple disease-causing bacterial species within one hour using a handheld device.
Published Astronomy: How do brown dwarfs form?
(via sciencedaily.com) Original source New observations provide insights into whether the birth of the giant planets takes a similar course to that of stars.
Published CHEOPS detects a 'rainbow' on an exoplanet
(via sciencedaily.com) Original source The CHEOPS space telescope is providing new information on the mysterious exoplanet WASP-76b. This ultra-hot giant is characterized by an asymmetry between the amount of light observed on its eastern terminator -- the fictitious line that separates its night side from its day side -- and that observed on its western terminator. This peculiarity is thought to be due to a 'glory', a luminous phenomenon similar to a rainbow, which occurs if the light from the star -- the 'sun' around which the exoplanet orbits -- is reflected by clouds made up of a perfectly uniform substance. If this hypothesis is confirmed, this would be the first detection of this phenomenon outside our solar system.
Published Stellar collisions produce strange, zombie-like survivors
(via sciencedaily.com) Original source Densely packed, fast-moving stars at the Milky Way's center can collide with each other. New research uses simulations to explore the outcomes of these collisions. Some collisions are more like 'violent high fives' while others are full-on mergers.
Published What four decades of canned salmon reveal about marine food webs
(via sciencedaily.com) Original source Researchers have shown that levels of anisakid worms -- a common marine parasite -- rose in two salmon species in the Gulf of Alaska and Bristol Bay over a 42-year period. The team discovered this by studying salmon caught, killed and canned from 1979 to 2021. Since anisakid worms have a complex life cycle involving multiple types of hosts, the researchers interpret their rising numbers as a potential sign of ecosystem recovery, possibly driven by rising numbers of marine mammals thanks to the 1972 Marine Mammal Protection Act.
Published First results from DESI make the most precise measurement of our expanding universe
(via sciencedaily.com) Original source Researchers have used the Dark Energy Spectroscopic Instrument to make the largest 3D map of our universe and world-leading measurements of dark energy, the mysterious cause of its accelerating expansion.
Published New research offers insight into the future understanding of MS and its treatments
(via sciencedaily.com) Original source Researchers have developed a new and unique blood test to measure the immune response to the Epstein Barr Virus (EBV) which is the leading risk factor for developing multiple sclerosis (MS). Their findings have implications for future basic research in further understanding the biology of EBV in MS, but also has the potential to be applied in clinical trials that target the virus.
