Published Lemurs use long-term memory, smell, and social cues to find food
(via sciencedaily.com) Original source How do foraging animals find their food? A new study shows that lemurs use smell, social cues, and long-term memory to locate hidden fruit -- a combination of factors that may have deep evolutionary roots.
Published Living with a killer: How an unlikely mantis shrimp-clam association violates a biological principle
(via sciencedaily.com) Original source When clams gamble on living with a killer, sometimes their luck may run out, according to a new study.
Published Researchers find gene which determines marsupial fur color
(via sciencedaily.com) Original source Fur is a defining characteristic of mammals, coming in a wide variety of colors and patterns -- thanks to a world-first study, we now know which genes make a marsupial's coat black or grey.
Published Study revisits Texas seismic activity occurring before 2017, confirming connection to wastewater injection
(via sciencedaily.com) Original source A new study by seismologists reexamines earthquakes in the Permian Basin that occurred before 2017 against the real-time data collected from earthquakes taking place after 2020. Results confirm that the seismicity occurring from 2009-2017 was causally linked to the underground injection of wastewater that is a byproduct of oil and gas extraction.
Published Seismic detectors measure soil moisture using traffic noise
(via sciencedaily.com) Original source Using state of the art techniques, researchers use vibrations from traffic to measure underground soil moisture.
Published New model refutes leading theory on how Earth's continents formed
(via sciencedaily.com) Original source Computational modeling shows that plate tectonics weren't necessary for early continents.
Published Fossil shows how penguins' wings evolved
(via sciencedaily.com) Original source A tiny fossil penguin plays a huge role in the evolutionary history of the bird, an international study shows.
Published Climate anomalies may play a major role in driving cholera pandemics
(via sciencedaily.com) Original source New research suggests that an El Nino event may have aided the establishment and spread of a novel cholera strain during an early 20th-century pandemic, supporting the idea that climate anomalies could create opportunities for the emergence of new cholera strains.
Published Half a billion-year-old spiny slug reveals the origins of mollusks
(via sciencedaily.com) Original source Exceptional fossils with preserved soft parts reveal that the earliest mollusks were flat, armored slugs without shells. The new species, Shishania aculeata, was covered with hollow, organic, cone-shaped spines. The fossils preserve exceptionally rare detailed features which reveal that these spines were produced using a sophisticated secretion system that is shared with annelids (earthworms and relatives).
Published Warming stops tiny organisms working together
(via sciencedaily.com) Original source Hotter conditions prevent two tiny organisms working together for mutual benefit, new research shows.
Published Towards smart cities: Predicting soil liquefaction risk using artificial intelligence
(via sciencedaily.com) Original source Soil liquefaction that results in infrastructure damage has long been a point of contention for urban planners and engineers. Accurately predicting the soil liquefaction risk of a region could help overcome this challenge. Accordingly, researchers applied artificial intelligence to generate soil liquefaction risk maps, superseding already published risk maps.
Published Mass extinction 66 million years ago triggered rapid evolution of bird genomes
(via sciencedaily.com) Original source Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds.
Published Researchers explore cancer susceptibility in birds
(via sciencedaily.com) Original source In one of the largest studies of cancer susceptibility across bird species, researchers describe an intriguing relationship between reproductive rates and cancer susceptibility.
Published Scientists discover entirely new wood type that could be highly efficient at carbon storage
(via sciencedaily.com) Original source Researchers undertaking an evolutionary survey of the microscopic structure of wood from some of the world's most iconic trees and shrubs have discovered an entirely new type of wood.
Published Platypus and chicken reveal how chromosomes balance between the sexes
(via sciencedaily.com) Original source Geneticists uncover new insights into how sex chromosome systems work in the platypus and the chicken -- which will lead to better understandings of our own sex chromosome evolution and gene regulation.
Published How researchers turn bacteria into cellulose-producing mini-factories
(via sciencedaily.com) Original source Researchers have modified certain bacteria with UV light so that they produce more cellulose. The basis for this is a new approach with which the researchers generate thousands of bacterial variants and select those that have developed into the most productive.
Published Scientists untangle interactions between the Earth's early life forms and the environment over 500 million years
(via sciencedaily.com) Original source The atmosphere, the ocean and life on Earth interacted over the past 500-plus million years in ways that improved conditions for early organisms to thrive. Now, an interdisciplinary team of scientists has produced a perspective article of this co-evolutionary history.
Published The ancestor of all modern birds probably had iridescent feathers
(via sciencedaily.com) Original source Birds tend to be more colorful in the tropics, and scientists wanted to find out how they got there: if colorful feathers evolved in the tropics, or if tropical birds have brightly-colored ancestors that came to the region from somwhere else. Scientists built a database of 9,409 birds to explore the spread of color across the globe. They found that iridescent, colorful feathers originated 415 times across the bird tree of life, and in most cases, arose outside of the tropics -- and that the ancestor of all modern birds likely had iridescent feathers, too.
Published Lampreys possess a 'jaw-dropping' evolutionary origin
(via sciencedaily.com) Original source Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates.
Published Ancient marine animal had inventive past despite being represented by few species
(via sciencedaily.com) Original source Brachiopods were evolving in new directions but this did not turn into evolutionary success in terms of the numbers of species, researchers have found.
