Published Tsetse fly fertility damaged after just one heatwave, study finds
(via sciencedaily.com) Original source The fertility of both female and male tsetse flies is affected by a single burst of hot weather, researchers have found.
Published A simple and robust experimental process for protein engineering
(via sciencedaily.com) Original source A protein engineering method using simple, cost-effective experiments and machine learning models can predict which proteins will be effective for a given purpose, according to a new study.
Published Who knew that coprophagy was so vital for birds' survival?
(via sciencedaily.com) Original source New research explains how eating feces (known as coprophagy) shapes wild birds' digestive tracts (gut biota), enabling them to absorb lost or deficient nutrients and adjust to seasonal variations in food sources.
Published Giant sequoias are a rapidly growing feature of the UK landscape
(via sciencedaily.com) Original source Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study.
Published Exploring arctic plants and lichens: An important conservation baseline for Nunavut's newest and largest territorial park
(via sciencedaily.com) Original source A comprehensive study of the floristic diversity of Agguttinni Territorial Park, Nunavut's newest and largest Territorial Park, has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area on northern Baffin Island. Through a combination of extensive fieldwork in 2021 and examination of hundreds of existing herbarium specimens, the authors have documented species newly reported for Baffin Island and have crafted a biodiversity baseline important for park management and conservation.
Published New study quantifies health impacts from oil and gas flaring in U.S.
(via sciencedaily.com) Original source A new study finds that pollution from oil and gas venting and flaring results in $7.4 billion in health damages, more than 700 premature deaths, and 73,000 asthma exacerbations among children annually. Researchers also conclude that emissions are underreported and controlling emissions is not only profitable for operators, but also can significantly improve public health in surrounding communities.
Published Scientists find weak points on Epstein-Barr virus
(via sciencedaily.com) Original source Studies of interactions between two lab-generated monoclonal antibodies (mAbs) and an essential Epstein-Barr virus (EBV) protein have uncovered targets that could be exploited in designing treatments and vaccines for this extremely common virus.
Published Vehicle brakes produce charged particles that may harm public health
(via sciencedaily.com) Original source Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests those particles may be more harmful to health than particles exiting the tailpipe.
Published AI making waves in marine data collection
(via sciencedaily.com) Original source Numerous measurement stations around the world provide us with data about air quality, allowing us to enhance it. Although we are increasingly collecting data from marine areas, access to such data is considerably more challenging. Signals are poorly transmitted through water, differences in both pressure and currents hinder measurement devices and there is an absence of pre-constructed computing infrastructure. Could intelligent technologies help us improve marine data collection?
Published How a natural compound from sea squirts combats cancer
(via sciencedaily.com) Original source Trabectedin, a promising drug derived from the sea squirt Ecteinascidia turbinata, has shown potential in combating cancers resistant to conventional treatments. However, its precise mechanism of action has remained elusive -- until now.
Published Air filters and scheduled window opening can reduce classroom pollution by up to 36%
(via sciencedaily.com) Original source To improve air quality in classrooms, schools should use air purifiers during the school day and open the windows after hours. That's according to a new study.
Published Rice paddy snake diversification was driven by geological and environmental factors in Thailand, molecular data suggests
(via sciencedaily.com) Original source A new study of rice paddy snakes in Southeast Asia gives key details to their diversification and natural history, adding molecular evidence that the rise of the Khorat Plateau and subsequent environmental shifts in Thailand may have altered the course of the snakes' evolution some 2.5 million years ago.
Published Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation
(via sciencedaily.com) Original source Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.
Published A coral superhighway in the Indian Ocean
(via sciencedaily.com) Original source Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'
Published Rainforest's next generation of trees threatened 30 years after logging
(via sciencedaily.com) Original source Rainforest seedlings are more likely to survive in natural forests than in places where logging has happened -- even if tree restoration projects have taken place, new research shows.
Published Scientists propose new theory that explains sand ripples on Mars and on Earth
(via sciencedaily.com) Original source Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?
Published Climate policies to reduce motor vehicle emissions can improve children's health, save money
(via sciencedaily.com) Original source A new study finds that policies to reduce carbon dioxide (CO2) emissions from motor vehicles combined with investments in electric vehicles and public transportation would reduce air pollution and bring large benefits to children's health. They would also save money.
Published Higher carnivorous dinosaur biodiversity of famous Kem Kem beds, Morocco
(via sciencedaily.com) Original source An international team of palaeontologists applied recently developed methods to measure theropod (carnivorous) dinosaur species diversity. The newly applied method uses both traditional phylogenetic analysis, discriminant analysis as well as machine learning.
Published Pronghorn population declining due to human development
(via sciencedaily.com) Original source A new article looked at 40 years of data collected on 40 pronghorn herds residing in the Wyoming Basin Shrub Steppe. Overall, 80% of the herds saw a decrease in productivity, and nearly 43% saw a significant decrease. After looking at a number of variables that could potentially contribute to the decline, the researchers identified the two most strongly associated: development of oil and gas resources and woody encroachment.
Published Gene flow in giraffes and what it means for their conservation
(via sciencedaily.com) Original source Giraffes, with their bizarre body plan, have always held a special place in the minds of evolutionary biologists and non-experts alike. In a new study whole-genome sequencing data was used to investigate the evolutionary processes occurring within giraffes. In particular, the authors were interested in establishing whether different populations of giraffes really have been isolated from each other for extended periods of time, which is normally a requirement before new species can arise.
