The NSF-DOE Vera C. Rubin Observatory in Chile has unveiled the very first “mega” images of the cosmos obtained thanks to the extraordinary features and wide-field view of its LSST camera—the largest in the world. The camera took nearly two decades to build and involved hundreds of scientists across the globe, including a number of CNRS teams. The world-wide First Look unveiling event is held on 23 June at the National Academy of Sciences in Washington, D.C. The impressive, car-sized…
New survey shows only 1% of men consider bone health a top concern; what they don’t know can hurt them COLUMBUS, Ohio – Weak bones can have deadly consequences. Women often get bone density tests to screen for osteoporosis, yet many men don’t even realize they are at risk until they suffer a major fracture. June is Men’s Health Awareness Month, with a focus on raising awareness about osteoporosis in men. A new survey commissioned by The Ohio State University…
Trees can offer up to 30 degrees of shade relief from the blistering desert sun, but don’t cool the city’s air temperature as much as trees in less dry environments. Earth is hotter than it has been in 125,000 years, scientists say, and Las Vegas continues to break temperature records. The extreme heat claimed more than 500 lives in southern Nevada last year alone, and scientists and city officials are clamoring for solutions. Planting and preserving the city’s street trees…
Discovery reveals pulsing mantle plume beneath Ethiopia, where a new ocean is forming Research led by Earth scientists at the University of Southampton has uncovered evidence of rhythmic surges of molten mantle rock rising from deep within the Earth beneath Africa. These pulses are gradually tearing the continent apart and forming a new ocean. The findings, published in Nature Geoscience, reveal that the Afar region in Ethiopia is underlain by a plume of hot mantle that pulses upward like a…
Research shows these channels allow seawater and nutrients to flow in and out, helping to maintain reef health over millions of years. Volcanic islands, such as the islands of Hawaii and the Caribbean, are surrounded by coral reefs that encircle an island in a labyrinthine, living ring. A coral reef is punctured at points by reef passes — wide channels that cut through the coral and serve as conduits for ocean water and nutrients to filter in and out. These…
The decrease growed in magnitude over time, with no evidence of the rates rebounding Among the biggest culprits of plastic pollution in the ocean and along shorelines are thin plastic shopping bags, which have low recycling rates and often become litter when they blow away in the wind. Once there, they can entangle animals and break down into harmful microplastics. As awareness of this problem has grown, more than 100 countries have instituted bans or fees on plastic bags. But…
Creating AI-focused curriculum and teaching employees how to use AI are priorities of many countries Artificial intelligence is spreading into many aspects of life, from communications and advertising to grading tests. But with the growth of AI comes a shake-up in the workplace. New research from the University of Georgia is shedding light on how different countries are preparing for how AI will impact their workforces. According to previous research, almost half of today’s jobs could vanish over the next 20 years. But it’s not…
A research team from the Alfred Wegener Institute has for the first time gained insights into a current in the Barents Sea which affects Arctic sea ice In the last few decades, the Arctic sea ice has receded ever further, including increasingly in winter when the extent of sea ice is at its most prominent. One of the main drivers of this development is thought to be the warming of Atlantic water that flows from Europe’s Norwegian Sea into the…
The idea seems futuristic: At ETH Zurich, various disciplines are working together to combine conventional materials with bacteria, algae and fungi. The common goal: to create living materials that acquire useful properties thanks to the metabolism of microorganisms – “such as the ability to bind CO2 from the air by means of photosynthesis,” says Mark Tibbitt, Professor of Macromolecular Engineering at ETH Zurich. An interdisciplinary research team led by Tibbitt has now turned this vision into reality: it has stably…
Astronomers have created a galactic masterpiece: an ultra-detailed image that reveals previously unseen features in the Sculptor Galaxy. Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT), they observed this nearby galaxy in thousands of colours simultaneously. By capturing vast amounts of data at every single location, they created a galaxy-wide snapshot of the lives of stars within Sculptor. “Galaxies are incredibly complex systems that we are still struggling to understand,” says ESO researcher Enrico Congiu, who led a…
In a world-first discovery, researchers have shown that Australia’s iconic Bogong moth uses constellations of stars and the Milky Way to navigate hundreds of kilometres across the country during its annual migration – making it the first known invertebrate to rely on a stellar compass for long-distance travel. The landmark study, published today (Thursday 19 June) in Nature, reveals how this unassuming nocturnal moth combines celestial navigation with Earth’s magnetic field to pinpoint a specific destination it has never visited…
New research reveals the importance of winter sea ice in the year-to-year variability of the amount of atmospheric CO2 absorbed by a region of the Southern Ocean. In years when sea ice lasts longer in winter, the ocean will overall absorb 20% more CO2 from the atmosphere than in years when sea ice forms late or disappears early. This is because sea ice protects the ocean from strong winter winds that drive mixing between the surface of the ocean and…
Trophic relationships are key to understanding changes in the distribution of certain species, according to a study led by the US, involving experts from 26 countries An international team led by the University of Seville, La Sapienza University of Rome and the Institute of Nature Conservation in Poland has studied how interactions between species affect the distribution of brown bears in Europe and Turkey. It has been found that the distribution of bears on a continental scale is largely explained…
Study links coffee consumption to lower risk of all-cause mortality; benefits diminished with additives While you’re probably not pouring your morning cup for the long-term health benefits, coffee consumption has been linked to lower risk of mortality. In a new observational study, researchers from the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University found the association between coffee consumption and mortality risk changes with the amount of sweeteners and saturated fat added to…
Research from Carnegie Mellon’s School of Computer Science suggests prompt engineering could be as important as coding Today’s generative artificial intelligence models can create everything from images to computer applications, but the quality of their output depends largely on the prompt a human user provides. Carnegie Mellon University researchers have proposed a new approach for teaching everyday users how to create these prompts and improving their interactions with generative artificial intelligence models. The method, called Requirement-Oriented Prompt Engineering (ROPE), shifts…
Huntington’s disease has long defied attempts to rescue suffering neurons. A new study in Cell Reports shows that transplanting healthy human glial progenitor cells into the brains of adult animal models of the disease not only slowed motor and cognitive decline but also extended lifespan. These findings shift our understanding of Huntington’s pathology and open a potential path to cell-based therapies in adults already showing symptoms. “Glia are essential caretakers of neurons,” said Steve Goldman, MD, PhD, co-director of the…
