Published Prenatal air pollution exposure linked to severe newborn respiratory distress
(via sciencedaily.com) Original source Prenatal exposure to air pollution increases the risk of severe respiratory distress in newborn babies, according to new research. The risk increases with exposure specifically to fine particulate matter (PM2.5) and nitrogen dioxide (NO2), which occur in wildfire and cigarette smoke and vehicle emissions, among other sources.
Published How a walk in nature restores attention
(via sciencedaily.com) Original source New research by psychologists demonstrates a peaceful walk through a natural setting enhances attention.
Published Compounding risks of atmospheric river storms
(via sciencedaily.com) Original source When storms hit back-to-back, the flooding -- and economic damages -- are even worse than expected.
Published Moth keeps a firm eye on the proboscis
(via sciencedaily.com) Original source Just as when we humans reach for objects, the hummingbird hawk moth uses its visual sense to place its long proboscis precisely on a flower to search for nectar, according to biologists. This is why the moth is a great model organism for research into the visual control of appendages.
Published Endangered seabird shows surprising individual flexibility to adapt to climate change
(via sciencedaily.com) Original source New research finds that individual behavioural flexibility and not evolutionary selection is driving the northward shift of Balearic shearwaters. The findings were revealed through a decade-long study which tagged individual birds. The results indicate that individual animals may have greater behavioural flexibility to respond to climate change impacts than previously thought.
Published Researchers spying for signs of life among exoplanet atmospheres
(via sciencedaily.com) Original source The next generation of advanced telescopes could sharpen the hunt for potential extraterrestrial life by closely scrutinizing the atmospheres of nearby exoplanets, new research suggests.
Published Probiotics promote weight loss in obese dogs
(via sciencedaily.com) Original source New research demonstrates how probiotics can reshape the gut microbiome and energy metabolism in dogs.
Published Back from the dead: Tropical tree fern repurposes its dead leaves
(via sciencedaily.com) Original source Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these 'zombie leaves,' reversing the flow of water to draw nutrients back into the plant.
Published How did humans learn to walk? New evolutionary study offers an earful
(via sciencedaily.com) Original source A new study, which centers on evidence from skulls of a 6-million-year-old fossil ape, Lufengpithecus, offers important clues about the origins of bipedal locomotion courtesy of a novel method: analyzing its bony inner ear region using three-dimensional CT-scanning. The inner ear appears to provide a unique record of the evolutionary history of ape locomotion.
Published Rising sea levels could lead to more methane emitted from wetlands
(via sciencedaily.com) Original source A Bay Area wetlands ecosystem that was expected to serve as a carbon sink is emitting surprisingly high levels of methane, a potent greenhouse gas. The study suggests factors governing carbon cycles in these habitats are even more complex than we thought.
Published Astronomers spot 18 black holes gobbling up nearby stars
(via sciencedaily.com) Original source Scientists have identified 18 new tidal disruption events (TDEs) -- extreme instances when a nearby star is tidally drawn into a black hole and ripped to shreds. The detections more than double the number of known TDEs in the nearby universe.
Published Sound-powered sensors stand to save millions of batteries
(via sciencedaily.com) Original source Researchers are developing a new type of sensor that reacts to certain sound waves, causing it to vibrate. The sensor is a metamaterial that acquires its special properties through the structuring of the material. Passive sound-sensitive sensors could be used to monitor buildings, earthquakes or certain medical devices and save millions of batteries.
Published Excavated dolmen in Sweden one of the oldest in Scandinavia
(via sciencedaily.com) Original source The first analysis results now confirm that the grave in Tiarp is one of the oldest stone burial chambers in Sweden. The researchers noted that some parts of the people buried in the grave are missing, such as skulls and thigh bones, posing intriguing questions for archaeologists.
Published First-ever sighting of a live newborn great white
(via sciencedaily.com) Original source Great whites, the largest predatory sharks in the world with the most fatal attacks on humans, are tough to imagine as newborn babies. That is partially because no one has seen one in the wild, it seems, until now.
Published High-efficiency carbon dioxide electroreduction system reduces our carbon footprint and progressing carbon neutrality goals
(via sciencedaily.com) Original source Global warming continues to pose a threat to human society and the ecological systems, and carbon dioxide accounts for the largest proportion of the greenhouse gases that dominate climate warming. To combat climate change and move towards the goal of carbon neutrality, researchers have developed a durable, highly selective and energy-efficient carbon dioxide (CO2) electroreduction system that can convert CO2 into ethylene for industrial purposes to provide an effective solution for reducing CO2 emissions.
Published Researchers control biofilm formation using optical traps
(via sciencedaily.com) Original source Researchers showed that biofilm formation can be controlled with laser light in the form of optical traps. The findings could allow scientists to harness biofilms for various bioengineering applications.
Published Robot trained to read braille at twice the speed of humans
(via sciencedaily.com) Original source Researchers have developed a robotic sensor that incorporates artificial intelligence techniques to read braille at speeds roughly double that of most human readers.
Published Scientists develop novel method to estimate biodiversity loss in Singapore over the past two centuries
(via sciencedaily.com) Original source Scientists have employed novel statistical methods to reveal the extent of biodiversity loss in Singapore over the past two centuries. The study paints the most accurate picture to date of the ecological impact of deforestation and urban development in the tropical city-state. From a comprehensive dataset, the study estimated that Singapore has lost 37 per cent of its species.
Published Cosmic building blocks of life discovered through the electron microscope
(via sciencedaily.com) Original source Meteorites are fragments of asteroids which find their way to Earth as shooting stars and provide information on the origins of our solar system. A team of researchers has examined the so-called Winchcombe meteorite and demonstrated the existence in it of nitrogen compounds such as amino acids and heterocyclic hydrocarbons -- without applying any chemical treatment and by using a new type of detector design.
Published How obesity dismantles our mitochondria
(via sciencedaily.com) Original source Researchers found that when mice were fed a high-fat diet, mitochondria within their fat cells broke apart and were less able to burn fat, leading to weight gain. They also found they could reverse the effect by targeting a single gene, suggesting a new treatment strategy for obesity.
