Published DNA repair discovery could improve biotechnology
(via sciencedaily.com) A team of researchers has made a discovery that may have implications for therapeutic gene editing strategies, cancer diagnostics and therapies and other advancements in biotechnology.
Published Wisconsin cave holds tantalizing clues to ancient climate changes, future shifts
(via sciencedaily.com) A newly published study of a stalagmite found in Cave of the Mounds reveals previously undetected history of the local climate going back thousands of years. Researchers describe evidence for an ice age punctuated by massive and abrupt warming events across much of the Northern Hemisphere.
Published Resurrected supernova provides missing link
(via sciencedaily.com) Astronomers have discovered a supernova exhibiting unprecedented rebrightening at millimeter wavelengths, providing an intermediate case between two types of supernovae: those of solitary stars and those in close-binary systems.
Published How consciousness in animals could be researched
(via sciencedaily.com) Animal consciousness should not be thought of as a light switch, which can be on or off, philosophers say. They advocate a different approach.
Published Researchers propose a simple, inexpensive approach to fabricating carbon nanotube wiring on plastic films
(via sciencedaily.com) Researchers have developed an inexpensive method for fabricating multi-walled carbon nanotubes (MWNTs) on a plastic film. The proposed method is simple, can be applied under ambient conditions, reuses MWNTs, and produces flexible wires of tunable resistances without requiring additional steps. It eliminates several drawbacks of current fabrication methods, making it useful for large-scale manufacturing of carbon wiring for flexible all-carbon devices.
Published Earlier take-off could lead to fewer bumblebees and less pollination
(via sciencedaily.com) With the arrival of spring, bumblebee queens take their first wing beat of the season and set out to find new nesting sites. But they are flying earlier in the year, as a result of a warmer climate and a changing agricultural landscape, according to new research.
Published Putting a price tag on the amenity value of private forests
(via sciencedaily.com) When it comes to venturing into and enjoying nature, forests are the people's top choice -- at least in Denmark. This is also reflected in the sales prices of properties with private forest. But beyond earnings potential, this study puts a price tag on the so-called amenity value of Danish private forests.
Published Bald eagles aren't fledging as many chicks due to avian influenza
(via sciencedaily.com) Bald eagles are often touted as a massive conservation success story due to their rebound from near extinction in the 1960s. But now a highly infectious virus may put that hard-fought comeback in jeopardy. New research showed highly pathogenic avian influenza, also known as H5N1, is killing off unprecedented numbers of mating pairs of bald eagles.
Published U.S. birds' Eastern, Western behavior patterns are polar opposites
(via sciencedaily.com) Scientists have established what could be considered a baseline map of annual avian functional and species diversity patterns in the U.S., finding that functional diversity patterns in the West, where species and functional richness are both highest during the breeding season, are the polar opposite of what is seen in the East, where functional diversity is lowest when species richness is high.
Published Edible electronics: How a seaweed second skin could transform health and fitness sensor tech
(via sciencedaily.com) Scientists have developed biodegradable algae-based hydrogels for strain sensing devices -- such as those used in health monitors worn by runners and hospital patients to track heart rate -- using natural elements like rock salt, water and seaweed, combined with graphene. As well as being more environmentally friendly than polymer-based hydrogels, commonly used in health sensor technology, the graphene algae sensors perform strongly in terms of sensitivity.
Published Researchers provide proof of the helical coiling of condensed chromosomes
(via sciencedaily.com) Original source In early cytological studies chromatids of metaphase chromosomes were suggested to coil into a spiral called chromonema. This assumption was recently supported by chromosomce conformation capture sequencing. Still, the direct visualization of the coiled chromonema confirming the helical model was lacking. Now, an international research team provides the direct proof of the helical coiling of condensed chromatids via super-resolution microscopy of specifically labelled chromonema regions.
Published 74,000 fruit fly brain images released
(via sciencedaily.com) Neuroscience research just got a little bit easier, thanks to the release of tens of thousands of images of fruit fly brain neurons.
Published Hansel and Gretel's breadcrumb trick inspires robotic exploration of caves on Mars and beyond
(via sciencedaily.com) Future space missions likely will send robots to scout out underground habitats for astronauts. Engineers have now developed a system that would enable autonomous vehicles to explore caves, lava tubes and even oceans on other worlds on their own.
Published The future of touch
(via sciencedaily.com) Haptic holography promises to bring virtual reality to life, but a new study reveals a surprising physical obstacle that will need to be overcome.
Published Ultracool dwarf binary stars break records
(via sciencedaily.com) Astrophysicists have discovered the tightest ultracool dwarf binary system ever observed. The two stars are so close that it takes them less than one Earth day to revolve around each other. In other words, each star's 'year' lasts just 17 hours.
Published Ice-cold electron beams for ultra-compact X-ray lasers
(via sciencedaily.com) Original source Ice-cold electron beams could pave the way to reducing X-ray free-electron lasers (X-FELs) to a fraction of their current size.
Published Hubble captures movie of DART asteroid impact debris
(via sciencedaily.com) In 2022 NASA embarked on a bold experiment to see if they could change an asteroid's velocity by smacking it with a ballistic probe -- kind of like hitting it with a hammer. This experiment was to test a potential technique to someday deflect an asteroid on a collision course to Earth. Perhaps, for the first time in the history of the universe, an intelligent planetary species sought ways to avoid its own potential extinction by threats from outer space (something the dinosaurs, who were wiped out 65 million years ago by a rogue asteroid, never evolved to accomplish).
Published Study forecasts tile drainage and crop rotation changes for nitrogen loss
(via sciencedaily.com) Midwestern agriculture contributes the vast majority of nitrogen in the Gulf of Mexico, causing an oxygen-starved hypoxic zone and challenging coastal economies. State and federal policies have tried for decades to provide solutions and incentives, but the hypoxic zone keeps coming back. A recent study offers a new way to understand Midwestern nitrogen dynamics and forecasts future nitrogen loads under various management scenarios across the region.
Published Bronze Age well contents reveal the history of animal resources in Mycenae, Greece
(via sciencedaily.com) Original source A large Bronze Age debris deposit in Mycenae, Greece provides important data for understanding the history of animal resources at the site, according to a new study.
Published Waxing and waning of environment influences hominin dispersals across ancient Iran
(via sciencedaily.com) A world-first model of paleoclimate and hydrology in Iran has highlighted favourable routes for Neanderthals and modern human expansions eastwards into Asia. The findings reveal that multiple humid periods in ancient Iran led to the expansions of human populations, opening dispersal route across the region, and the possible interactions of species such as Neanderthals and our own Homo sapiens.
