Published In-situ observation of nanoscale heat propagation
(via sciencedaily.com) Original source A research team has developed a technique that enables the nanoscale observation of heat propagation paths and behavior within material specimens. This was achieved using a scanning transmission electron microscope (STEM) capable of emitting a pulsed electron beam and a nanosized thermocouple -- a high-precision temperature measurement device.
Published The heat index -- how hot it really feels -- is rising faster than temperature
(via sciencedaily.com) Original source Researchers showed in 2022 that heat index calculations by NOAA based on analyses from the 1970s don't adequately reflect the heat stress humans feel during the extremes of heat and humidity accompanying climate change. Using their revised heat index, the researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days.
Published Bendable energy storage materials by cool science
(via sciencedaily.com) Original source Imaging being able to wear clothes that charge your gadgets just by wearing them. New research has brought us a step closer to achieving this reality.
Published Using light to produce medication and plastics more efficiently
(via sciencedaily.com) Original source Anyone who wants to produce medication, plastics or fertilizer using conventional methods needs heat for chemical reactions -- but not so with photochemistry, where light provides the energy. The process to achieve the desired product also often takes fewer intermediate steps. Researchers are now going one step further and are demonstrating how the energy efficiency of photochemical reactions can be increased tenfold. More sustainable and cost-effective applications are now tantalizingly close.
Published Advance for soft robotics manufacturing, design
(via sciencedaily.com) Original source Engineers propose a new quantitative framework to account for and predict the impact of temperature on the curing speed of platinum-catalyzed silicone elastomers. The findings could maximize throughput and minimize waste in the manufacturing of components for soft robotics and wearables.
Published Self-heating concrete is one step closer to putting snow shovels and salt out of business
(via sciencedaily.com) Original source Researchers recently reported on the science behind its special concrete, that can warm itself up when it snows, or as temperatures approach freezing.
Published Meteorology: Weak polar vortex makes weather more predictable
(via sciencedaily.com) Original source Events in the stratosphere are making long-range weather in Northern Europe easier to forecast, researchers have discovered.
Published Revolutionary method developed for mass-producing polymer solid electrolytes
(via sciencedaily.com) Original source Scientists have unveiled a groundbreaking technique for mass-producing polymer solid electrolytes, crucial components in batteries.
Published Diverse habitats help salmon weather unpredictable climate changes
(via sciencedaily.com) Original source Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.
Published Tropical birds could tolerate warming better than expected, study suggests
(via sciencedaily.com) Original source We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.
Published Ready for the storm: Researchers analyze infrastructure, demographics to see where tornadoes are most disruptive
(via sciencedaily.com) Original source Researchers examined demographics, infrastructure and more than seven decades of weather data to determine which places in Kentucky are most vulnerable to tornadoes.
Published Supply chain disruptions will further exacerbate economic losses from climate change
(via sciencedaily.com) Original source Global GDP loss from climate change will increase exponentially the warmer the planet gets when its cascading impact on global supply chains is factored in, finds a new study.
Published Drought, soil desiccation cracking, and carbon dioxide emissions: an overlooked feedback loop exacerbating climate change
(via sciencedaily.com) Original source Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change.
Published Molecular simulations of ammonia mixtures support search for renewable fuels
(via sciencedaily.com) Original source Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.
Published Summer solstice triggers synchronized beech tree reproduction across Europe
(via sciencedaily.com) Original source A new study has found that the summer solstice acts as a 'starting gun' to synchronize beech tree reproduction across vast distances in Europe, affecting ecosystem functions.
Published Spiral wrappers switch nanotubes from conductors to semiconductors and back
(via sciencedaily.com) Original source By wrapping a carbon nanotube with a ribbon-like polymer, researchers were able to create nanotubes that conduct electricity when struck with low-energy light that our eyes cannot see. In the future, the approach could make it possible to optimize semiconductors for applications ranging from night vision to new forms of computing.
Published History repeats as Coral Bay faces mass loss of coral and fish life
(via sciencedaily.com) Original source A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.
Published India's water problems set to get worse as the world warms
(via sciencedaily.com) Original source Winter storms known as western disturbances that provide crucial snow and rainfall to northern India are arriving significantly later in the year.
Published Study explores impacts of Arctic warming on daily weather patterns in the U.S.
(via sciencedaily.com) Original source Arctic sea ice is shrinking as the world continues to warm, and a new study may provide a better understanding of how the loss of this ice may impact daily weather in the middle latitudes, like the United States.
Published Preventing magnet meltdowns before they can start
(via sciencedaily.com) Original source High-temperature superconductor magnets have the potential to lower the costs of operating particle accelerators and enable powerful new technologies like fusion reactors. But quenches -- the sudden, destructive events wherein a part of the material loses superconductivity -- are a major barrier to their deployment. Scientists have developed an approach to prevent quenches altogether, rather than simply trying to manage them after they occur.
