Roadmap for detecting changes in ocean due to climate change

Ocean and sky (stock image). Credit: © Iakov Kalinin / Adobe Stock Sea temperature and ocean acidification have climbed during the last three decades to levels beyond what is expected due to natural variation alone, a new study led by Princeton researchers finds. Meanwhile other impacts from climate change, such as changes in the activity…

Diet change needed to save vast areas of tropics

Grocery bag, assorted food (stock image). Credit: © samael334 / Adobe Stock One quarter of the world's tropical land could disappear by the end of the century unless meat and dairy consumption falls, researchers have warned. If the global demand for animal products continues to grow, large swathes of natural land will vanish potentially leading…

How many Earth-like planets are around sun-like stars?

Exoplanets concept illustration (stock image). Credit: © Dimitar Marinov / Adobe Stock A new study provides the most accurate estimate of the frequency that planets that are similar to Earth in size and in distance from their host star occur around stars similar to our Sun. Knowing the rate that these potentially habitable planets occur…

Scent brings all the songbirds to the yard

Black-capped chickadee (stock image). Credit: © Brian / Adobe Stock Chickadees can smell! That is the news from a study out of Lehigh University, the first to document naturally hybridizing songbirds' preference for the scent of their own species. Amber Rice, an evolutionary biologist at Lehigh, studies natural hybridization-when separate species come into contact and…

Poo’s clues: Moose droppings indicate Isle Royale ecosystem health

Moose (stock image). Credit: © Mark / Adobe Stock Given the choice between ice cream and vegetables, for many people it'll be the ice cream. But sometimes it depends on the situation. If you'd eaten ice cream every day for a week, you might prefer the salad. Human preferences for different foods often depend on…

Diarrhea-causing bacteria adapted to spread in hospitals

Washing hands in hospital setting (stock image). Credit: © CMP / Adobe Stock Scientists have discovered that the gut-infecting bacterium Clostridium difficile is evolving into two separate species, with one group highly adapted to spread in hospitals. Researchers at the Wellcome Sanger Institute, London School of Hygiene & Tropical Medicine and collaborators identified genetic changes…

Near-Earth asteroid 2006 QV89 not a threat for next century

Canada-France-Hawaii Telescope (stock image). Credit: © Fredy Thürig / Adobe Stock The existing astronomical observatories on Maunakea returned to operations this weekend, and it didn't take long for a significant result to be achieved, not only for science, but for assuring the safety of Earth. Observations of the near-Earth asteroid 2006 QV89 made on August…

Fluorescent glow may reveal hidden life in the cosmos

Fluorescence in marine life (stock image). Credit: © GeraldRobertFischer / Adobe Stock Astronomers have uncovered a new way of searching for life in the cosmos. Harsh ultraviolet radiation flares from red suns, once thought to destroy surface life on planets, might help uncover hidden biospheres. Their radiation could trigger a protective glow from life on…

Hurricanes drive the evolution of more aggressive spiders

Palm trees in storm (stock image). Credit: © Lisa / Adobe Stock Researchers at McMaster University who rush in after storms to study the behaviour of spiders have found that extreme weather events such as tropical cyclones may have an evolutionary impact on populations living in storm-prone regions, where aggressive spiders have the best odds…

Jurassic world of volcanoes found in central Australia

Volcanic eruption (stock image). Credit: © Fredy Thürig / Adobe Stock An international team of subsurface explorers from the University of Adelaide in Australia and the University of Aberdeen in Scotland have uncovered a previously undescribed 'Jurassic World' of around 100 ancient volcanoes buried deep within the Cooper-Eromanga Basins of central Australia. The Cooper-Eromanga Basins…

Rising summer heat could soon endanger travelers on annual Muslim pilgrimage

Muslims gathered in Mecca (stock image). Credit: © hikrcn / Adobe Stock Over two million Muslim travelers just finished the annual religious pilgrimage to Mecca, Saudi Arabia, traveling during some of the country's hottest weather. New research finds pilgrims in future summers may have to endure heat and humidity extreme enough to endanger their health.…

A new timeline of Earth’s cataclysmic past

Asteroid impact illustration (stock image). Credit: © Andrea Danti / Adobe Stock Welcome to the early solar system. Just after the planets formed more than 4.5 billion years ago, our cosmic neighborhood was a chaotic place. Waves of comets, asteroids and even proto-planets streamed toward the inner solar system, with some crashing into Earth on…

Big brains or big guts: Choose one

Ptarmigan (stock image). Credit: © Christof Muller / Adobe Stock Big brains can help an animal mount quick, flexible behavioral responses to frequent or unexpected environmental changes. But some birds just don't need 'em. A global study comparing 2,062 birds finds that, in highly variable environments, birds tend to have either larger or smaller brains…

Scientists create artificial catalysts inspired by living enzymes

Molecular models (stock image). Credit: © shotsstudio / Adobe Stock All living organisms depend on enzymes -- molecules that speed up biochemical reactions that are essential for life. Scientists have spent decades trying to create artificial enzymes capable of cranking out important chemicals and fuels at an industrial scale with performance rivaling their natural counterparts.…

Pupil dilation and heart rate, analyzed by AI, may help spot autism early

Child's eye (stock image). Credit: © Anton / Adobe Stock Autism and other neurodevelopmental disorders often aren't diagnosed until a child is a few years of age, when behavioral interventions and speech/occupational therapy become less effective. But new research this week in PNAS suggests that two simple, quantifiable measures -- spontaneous fluctuations in pupil dilation…

Physicists mash quantum and gravity and find time, but not as we know it

Quantum time abstract concept (stock illustration). Credit: © Stillfx / Adobe Stock A University of Queensland-led international team of researchers say they have discovered "a new kind of quantum time order." UQ physicist Dr Magdalena Zych said the discovery arose from an experiment the team designed to bring together elements of the two big --…

First cells may have emerged because building blocks of proteins stabilized membranes

Cells abstract illustration (stock image). Credit: © rost9 / Adobe Stock Life on Earth arose about 4 billion years ago when the first cells formed within a primordial soup of complex, carbon-rich chemical compounds. These cells faced a chemical conundrum. They needed particular ions from the soup in order to perform basic functions. But those…
