Published Human-wildlife overlap expected to increase across more than half of land on Earth by 2070
(via sciencedaily.com) Original source Human-wildlife overlap could increase across about 57% of the global lands by 2070 and could lead to more conflict between people and animals. Understanding where the overlap is likely to occur -- and which animals are likely to interact with humans in specific areas -- will be crucial information for urban planners, conservationists and countries that have pledged international conservation commitments.
Published Highest prediction of sea-level rise unlikely
(via sciencedaily.com) Original source A new study challenges as highly unlikely an alarming prediction of sea-level rise that -- while designated as low likelihood --earned a spot in the latest UN climate report for its projection that the collapse of polar ice sheets could make the world's oceans up to 50 feet higher by 2300. But researchers found that the model is based on inaccurate physics of how ice sheets retreat and break apart, though they stress that the accelerating loss of ice from Greenland and Antarctica is still dire.
Published New study reveals devastating power and colossal extent of a giant underwater avalanche off the Moroccan coast
(via sciencedaily.com) Original source New research has revealed how an underwater avalanche grew more than 100 times in size causing a massive trail of destruction as it traveled 2000km across the Atlantic Ocean seafloor off the North West coast of Africa. Researchers provide an unprecedented insight into the scale, force and impact of one of nature's mysterious phenomena, underwater avalanches.
Published To kill mammoths in the Ice Age, people used planted pikes, not throwing spears, researchers say
(via sciencedaily.com) Original source Archeologists say new findings might help resolve the debate about Clovis points and reshape how we think about what life was like roughly 13,000 years ago. After an extensive review of writings and artwork -- and an experiment with replica Clovis point spears -- a team of archaeologists says humans may have braced the butt of their weapons against the ground in a way that would impale a charging animal. The force would have driven the spear deeper into the predator's body, unleashing a more damaging blow than even the strongest prehistoric hunters would have been capable of by throwing or jabbing megafauna.
Published Using AI to link heat waves to global warming
(via sciencedaily.com) Original source Researchers used machine learning to determine how much global warming has influenced extreme weather events in the U.S. and elsewhere in recent years. Their approach could change how scientists study and predict the impact of climate change on extreme weather.
Published Chalk-based coating creates a cooling fabric
(via sciencedaily.com) Original source In the scorching heat of summer, anyone who spends time outside could benefit from a cooling fabric. While there are some textiles that reflect the sun's rays or wick heat away, current options require boutique fibers or complex manufacturing processes. But now, demonstrations of a durable chalk-based coating show it can cool the air underneath treated fabric by up to 8 degrees Fahrenheit.
Published Pilot study uses recycled glass to grow plants for salsa ingredients
(via sciencedaily.com) Original source Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.
Published Research shows reducing future global flooding hinges on cutting greenhouse gas emissions
(via sciencedaily.com) Original source Pioneering research forecasts worldwide flooding is likely to be significantly worse in future decades if countries fail to meet official pledges to cut carbon emissions.
Published Beetle that pushes dung with the help of 100 billion stars unlocks the key to better navigation systems in drones and satellites
(via sciencedaily.com) Original source An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites.
Published The power of face time: Insights from zebra finch courtship
(via sciencedaily.com) Original source A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. Researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody.
Published New heaviest exotic antimatter nucleus
(via sciencedaily.com) Original source Scientists studying the tracks of particles streaming from six billion collisions of atomic nuclei at the Relativistic Heavy Ion Collider (RHIC) -- an 'atom smasher' that recreates the conditions of the early universe -- have discovered a new kind of antimatter nucleus, the heaviest ever detected. Composed of four antimatter particles -- an antiproton, two antineutrons, and one antihyperon -- these exotic antinuclei are known as antihyperhydrogen-4.
Published Humpbacks are among animals who manufacture and wield tools
(via sciencedaily.com) Original source Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.
Published Incorporating humidity improves estimations of climate impacts on health
(via sciencedaily.com) Original source Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities. Climate change has measurable impacts on society, including on human mortality. However, current models to assess the health impacts of climate change do not account for every environmental parameter, especially humidity, which could influence heat stress perceived by the human body, leaving room for improvement. Researchers have now incorporated humidity data from hundreds of cities into so-called heat stress indicators (HSIs) and assessed their performances in predicting heat-related deaths.
Published New view of North Star reveals spotted surface
(via sciencedaily.com) Original source High-resolution images show large spots on the surface of Polaris.
Published 'Masters of shape-shifting': How darkling beetles conquered the world
(via sciencedaily.com) Original source Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.
Published Deadly sea snail toxin could be key to making better medicines
(via sciencedaily.com) Original source Scientists are finding clues for how to treat diabetes and hormone disorders in an unexpected place: a toxin from one of the most venomous animals on the planet.

Published Researchers uncover the secrets of 'plant puberty'
(via sciencedaily.com) Original source Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Analyzing 'Finnegans Wake' for novel spacing between punctuation marks
(via sciencedaily.com) Original source James Joyce's tome 'Finnegans Wake' famously breaks the rules of normal prose through its unusual, dreamlike stream of consciousness, and new work in chaos theory takes a closer look at how Joyce's challenging novel stands out mathematically. Researchers compared the distribution of punctuation marks in various experimental novels to determine the underlying order of 'Finnegans Wake' and by statistically analyzing the texts, researchers found the tome exhibits an unusual but statistically identifiable structure. The wide singularity spectrum was perfectly symmetrical, meaning sentence length variability follows an orderly curve.
Published Spectacular increase in the deuterium/hydrogen ratio in Venus' atmosphere
(via sciencedaily.com) Original source Our understanding of Venus' water history and the potential that it was once habitable in the past is being challenged by recent observations.
