Published Near chromosome-level genome of the Mojave poppy bee
(via sciencedaily.com) Original source Scientists have developed a near chromosome-level genome for the Mojave poppy bee, a specialist pollinator of conservation concern.
Published New and improved camera inspired by the human eye
(via sciencedaily.com) Original source Computer scientists have invented a camera mechanism that improves how robots see and react to the world around them. Inspired by how the human eye works, their innovative camera system mimics the tiny involuntary movements used by the eye to maintain clear and stable vision over time.
Published AI-powered study explores under-studied female evolution
(via sciencedaily.com) Original source Pioneering AI-powered research on butterflies has probed the under-studied evolution of females and adds to a debate between Charles Darwin and Alfred Russel Wallace.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread
(via sciencedaily.com) Original source Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published Soft, stretchy electrode simulates touch sensations using electrical signals
(via sciencedaily.com) Original source A team of researchers has developed a soft, stretchy electronic device capable of simulating the feeling of pressure or vibration when worn on the skin. This device represents a step towards creating haptic technologies that can reproduce a more varied and realistic range of touch sensations for applications such as virtual reality, medical prosthetics and wearable technology.
Published Ammonites' fate sealed by meteor strike that wiped out dinosaurs
(via sciencedaily.com) Original source Ammonites were not in decline before their extinction, scientists have found.
Published New mathematical model sheds light on the absence of breastfeeding in male mammals
(via sciencedaily.com) Original source Mathematicians ave put forward a hypothesis which suggests that the reason male mammals don't breastfeed might be driven by the rich community of microbes that lives in breast milk and which plays an important part in establishing the gut microbiome of the infant.
Published Last surviving woolly mammoths were inbred but not doomed to extinction
(via sciencedaily.com) Original source The last population of woolly mammoths was isolated on Wrangel Island off the coast of Siberia 10,000 years ago, when sea levels rose and cut the mountainous island off from the mainland. A new genomic analysis reveals that the isolated mammoths, who lived on the island for the subsequent 6,000 years, originated from at most 8 individuals but grew to 200--300 individuals within 20 generations. The researchers report that the Wrangel Island mammoths' genomes showed signs of inbreeding and low genetic diversity but not to the extent that it can explain their ultimate (and mysterious) extinction.
Published To protect corals from summer heatwaves, we should help their microbial symbionts evolve heat tolerance in the lab
(via sciencedaily.com) Original source Most coral reef restoration efforts involve restocking reefs with nursery-grown corals. However, if these corals are of the same stock as their wild counterparts, they will be equally vulnerable to the heat stress that caused the bleaching event in the first place. Researchers discuss the potential of improving corals' chances by inducing the evolution of heat tolerance in their symbionts -- the mutualistic microbes that provide corals with nutrients in exchange for shelter and that are expelled during coral bleaching.
Published Researchers find genetic stability in a long-term Panamanian hybrid zone of manakin birds
(via sciencedaily.com) Original source We often think of species as separate and distinct, but sometimes they can interbreed and create hybrids. When this happens consistently in a specific area, it forms what's known as a hybrid zone. These zones can be highly dynamic or remarkably stable, and studying them can reveal key insights into how species boundaries evolve -- or sometimes blur. Researchers now describe a hybrid zone between two manakin species in Panama that has overall remained relatively stable over the past 30 years.
Published New tool enables faster, more cost-effective genome editing of traits to improve agriculture sustainability
(via sciencedaily.com) Original source New research had the goal of reducing the time and cost it takes to bring an improved crop to the marketplace to improve agriculture sustainability.
Published Discovery of vast sex differences in cellular activity has major implications for disease treatment
(via sciencedaily.com) Original source The study reveals vast differences in gene activity within the mitochondria of males compared to females. This is the first study to test effects of all 37 genes in the mitochondrial genome -- genes that copepods and humans share. The study found that males demonstrate more activity across all protein-coding mitochondrial genes than females. Although the study looks at tiny marine organisms called copepods, the findings have weighty implications for human medicine.
Published New tomato, potato family tree shows that fruit color and size evolved together
(via sciencedaily.com) Original source A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.
Published Prying open the AI black box
(via sciencedaily.com) Original source Meet SQUID, a new computational tool. Compared with other genomic AI models, SQUID is more consistent, reduces background noise, and can yield better predictions regarding critical mutations. The new system aims to bring scientists closer to their findings' true medical implications.
Published Newly discovered dinosaur boasts big, blade-like horns
(via sciencedaily.com) Original source A new dinosaur has been identified and named. The dinosaur's name, Lokiceratops rangiformis, translates roughly to 'Loki's horned face that looks like a caribou.'
Published Wild yeasts from Patagonia could yield new flavors of lagers
(via sciencedaily.com) Original source New strains of yeast for brewing lager beers, created by hybridizing wild strains of yeast from Patagonia with brewer's yeast, can yield novel flavors and aromas, researchers report.
Published Interaction with insects accelerates plant evolution
(via sciencedaily.com) Original source Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.
Published Nile perch invasion triggered genetic bottlenecks in Lake Victoria's endemic cichlids
(via sciencedaily.com) Original source Newfound evidence reveals that the upsurge of the exotic Nile perch in Lake Victoria had long-lasting effects on the genetic diversity of various local cichlid species, report scientists. Through large-scale comparative genomic analyses, the researchers found concrete proof in the collective genome of multiple species that this artificially introduced perch decimated many local fish populations, causing a 'bottleneck effect.'
Published Previously uncharacterized parasite uncovered in fish worldwide
(via sciencedaily.com) Original source Using genome reconstruction, scientists unveiled a once 'invisible' fish parasite present in many marine fish world-wide that belongs to the apicomplexans, one of the most important groups of parasites at a clinical level. However, it had gone unnoticed in previous studies. The parasite is geographically and taxonomically widespread in fish species around the planet, with implications for commercial fishing and oceanic food webs.
Published Ancient polar sea reptile fossil is oldest ever found in Southern Hemisphere
(via sciencedaily.com) Original source An international team of scientists has identified the oldest fossil of a sea-going reptile from the Southern Hemisphere -- a nothosaur vertebra found on New Zealand's South Island. 246 million years ago, at the beginning of the Age of Dinosaurs, New Zealand was located on the southern polar coast of a vast super-ocean called Panthalassa. 'The nothosaur found in New Zealand is over 40 million years older than the previously oldest known sauropterygian fossils from the Southern Hemisphere.
