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 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 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 Lingering effects of Neanderthal DNA found in modern humans
(via sciencedaily.com) Original source Recent scientific discoveries have shown that Neanderthal genes comprise some 1 to 4% of the genome of present-day humans whose ancestors migrated out of Africa, but the question remained open on how much those genes are still actively influencing human traits -- until now.
Published Team finds reliable predictor of plant species persistence, coexistence
(via sciencedaily.com) Original source Ecological scientists have long sought ways to measure and predict how specific plant communities will fare over time. Which species in a diverse population will persist and coexist? Which will decline? What factors might contribute to continuing biodiversity? Researchers report on a new method for determining whether pairs or groups of plant species are likely to coexist over time.
Published New dino, 'Iani,' was face of a changing planet
(via sciencedaily.com) Original source A newly discovered plant-eating dinosaur may have been a species' 'last gasp' during a period when Earth's warming climate forced massive changes to global dinosaur populations.
Published Older trees accumulate more mutations than their younger counterparts
(via sciencedaily.com) Original source A study of the relationship between the growth rate of tropical trees and the frequency of genetic mutations they accumulate suggests that older, long-lived trees play a greater role in generating and maintaining genetic diversity than short-lived trees.
Published Saving moths may be just as important as saving the bees
(via sciencedaily.com) Original source Night-time pollinators such as moths may visit just as many plants as bees, and should also be the focus of conservation and protection efforts, a new study suggests.
Published The other side of the story: How evolution impacts the environment
(via sciencedaily.com) Original source Researchers show that an evolutionary change in the length of lizards' legs can have a significant impact on vegetation growth and spider populations on small islands in the Bahamas. This is one of the first times, the researchers say, that such dramatic evolution-to-environment effects have been documented in a natural setting.
Published Symbiotic and pathogenic fungi may use similar molecular tools to manipulate plants
(via sciencedaily.com) Original source Symbiotic and pathogenic fungi that interact with plants are distantly related and don't share many genetic similarities. Comparing plant pathogenic fungi and plant symbiotic fungi, scientists at the Sainsbury Laboratory Cambridge University (SLCU) have discovered that these remote relatives are using a similar group of proteins to manipulate and live within plants.
Published Phenomenal phytoplankton: Scientists uncover cellular process behind oxygen production
(via sciencedaily.com) Original source According to new research, the amount of oxygen in one of 10 breaths was made possible thanks to a newly identified cellular mechanism that promotes photosynthesis in marine phytoplankton. The new study identifies how a proton pumping enzyme (known as VHA) aids in global oxygen production and carbon fixation from phytoplankton.
Published Geneticists discover hidden 'whole genome duplication' that may explain why some species survived mass extinctions
(via sciencedaily.com) Original source Geneticists have unearthed a major event in the ancient history of sturgeons and paddlefish that has significant implications for the way we understand evolution. They have pinpointed a previously hidden 'whole genome duplication' (WGD) in the common ancestor of these species, which seemingly opened the door to genetic variations that may have conferred an advantage around the time of a major mass extinction some 200 million years ago.
Published Study leads to milestone advances in understanding lethal bronzing of palm trees
(via sciencedaily.com) Original source Scientists have identified a key chemical associated with lethal bronzing (LB) infected palm trees. LB is a bacterial disease that kills more than 20 species of palm trees in the Southern United States and Caribbean and has been devastating the Florida green industries for nearly two decades.
Published Plants can distinguish when touch starts and stops, study suggests
(via sciencedaily.com) Original source Even without nerves, plants can sense when something touches them and when it lets go, a study has found. In a set of experiments, individual plant cells responded to the touch of a very fine glass rod by sending slow waves of calcium signals to other plant cells, and when that pressure was released, they sent much more rapid waves. While scientists have known that plants can respond to touch, this study shows that plant cells send different signals when touch is initiated and ended.
Published Light conveyed by the signal transmitting molecule sucrose controls growth of plant roots
(via sciencedaily.com) Original source Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal transmitter for light-dependent root architecture.
Published That's not nuts: Almond milk yogurt packs an overall greater nutritional punch than dairy-based
(via sciencedaily.com) Original source In a nutritional comparison of plant-based and dairy yogurts, almond milk yogurt came out on top, according to new research.
Published 107-million-year-old pterosaur bones: Oldest in Australia
(via sciencedaily.com) Original source A team of researchers have confirmed that 107-million-year-old pterosaur bones discovered more than 30 years ago are the oldest of their kind ever found in Australia, providing a rare glimpse into the life of these powerful, flying reptiles that lived among the dinosaurs.
Published Groundbreaking images of root chemicals offer new insights on plant growth
(via sciencedaily.com) Original source Applying imaging technology to plant roots, researchers have developed a new understanding of chemicals that are responsible for plant growth. The chemical 'roadmap' identifies where key molecules are distributed along corn roots and how their placement factors into the plant's maturation.
Published Weevils, long-nosed beetles, are unsung heroes of pollination
(via sciencedaily.com) Original source Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, including ones whose entire life cycles are interwoven with a specific plant that they help pollinate.
Published Iron-rich rocks unlock new insights into Earth's planetary history
(via sciencedaily.com) Original source A new study suggests iron-rich ancient sediments may have helped cause some of the largest volcanic events in the planet's history.
