Published New solutions to keep drinking water safe as pesticide use skyrockets worldwide
(via sciencedaily.com) Original source Water scientists have proposed a more effective method of removing organic pesticides from drinking water, reducing the risk of contamination and potential health problems.
Published Targeted home systems to remove PFAS more cost-effective than system-wide solutions
(via sciencedaily.com) Original source PFAS, the potentially cancer-causing chemicals known as 'forever chemicals', have become an increasing concern in home drinking water. Solutions to reduce the risk of exposure range from mandated municipal-level water treatment to under-the-sink home treatment systems. But are consumers willing to foot the bill for an additional treatment system to help municipalities meet new federal drinking water regulations? Researchers found that they are, if it helps reduce the risk and fits their budget.
Published Could lead overcome reverse current and advance a green hydrogen economy?
(via sciencedaily.com) Original source Researchers developed a catalyst that enhances the stability of alkaline water electrolysis systems.
Published A breakthrough on the edge: One step closer to topological quantum computing
(via sciencedaily.com) Original source Researchers have achieved a significant breakthrough in quantum materials, potentially setting the stage for advancements in topological superconductivity and robust quantum computing.
Published The Gulf Stream is wind-powered and could weaken from climate change
(via sciencedaily.com) Original source New evidence of changes to the Gulf Stream during the last ice age could indicate additional sensitivity to future climatic changes, finds a new study.
Published Moving from the visible to the infrared: Developing high quality nanocrystals
(via sciencedaily.com) Original source Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small -- on the order of nanometers -- that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic spectrum.
Published Building materials for water-rich planets in the early solar system
(via sciencedaily.com) Original source Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These planetesimals continually supplied building materials for planets -- also for the Earth, whose original material contained little water. The Earth received its actual water through planetesimals, which emerged at low temperatures in the outer solar system, as shown by computational models carried out by an international research teach with participation by earth scientists.
Published Researcher finds lithium ion batteries a growing source of pollution
(via sciencedaily.com) Original source The use of certain substances in batteries is polluting air and water.
Published Study reveals environmental impact of artificial sweeteners
(via sciencedaily.com) Original source A recently published study demonstrates how sucralose affects the behavior of cyanobacteria -- an aquatic photosynthetic bacteria -- and diatoms, microscopic algae that account for more than 30% of the primary food production in the marine food chain.
Published Restored oyster sanctuaries host more marine life
(via sciencedaily.com) Original source Oysters sanctuaries in Chesapeake Bay are working for more than just oysters. Compared to nearby harvest areas, sanctuaries contain more abundant populations of oysters and other animal life--and the presence of two common parasites isn't preventing that.
Published New extremely fast carbon storage technology
(via sciencedaily.com) Original source A new way to store carbon captured from the atmosphere works much faster than current methods without the harmful chemical accelerants they require.
Published A 2D device for quantum cooling
(via sciencedaily.com) Original source Engineers have created a device that can efficiently convert heat into electrical voltage at temperatures lower than that of outer space. The innovation could help overcome a significant obstacle to the advancement of quantum computing technologies, which require extremely low temperatures to function optimally.
Published How dust pollution from shrinking Great Salt Lake affects communities disproportionately
(via sciencedaily.com) Original source Exposure to wind-blown dust from exposed playa of the Utah lake is worse in Hispanic neighborhoods, according to new research. Findings suggest restoring the lake could ease social inequities associated with air pollution.
Published Cool roofs are best at beating cities' heat
(via sciencedaily.com) Original source Painting roofs white or covering them with a reflective coating would be more effective at cooling cities like London than vegetation-covered 'green roofs,' street-level vegetation or solar panels, finds a new study led by UCL researchers.
Published A breakthrough in inexpensive, clean, fast-charging batteries
(via sciencedaily.com) Original source Scientists have created an anode-free sodium solid-state battery. This brings the reality of inexpensive, fast-charging, high-capacity batteries for electric vehicles and grid storage closer than ever.
Published A genetic algorithm for phononic crystals
(via sciencedaily.com) Original source Researchers tested phononic nanomaterials designed with an automated genetic algorithm that responded to light pulses with controlled vibrations. This work may help in the development of next-generation sensors and computer devices.
Published Early-onset El Niño means warmer winters in East Asia, and vice versa
(via sciencedaily.com) Original source Researchers have found that the early onset of El Nino around June leads to warm winter climates in Japan, while the late onset of El Nino is associated with colder winters. By analyzing 100-ensemble member climate simulations over the past 61 years, the team found that the warming of the tropical Indian Ocean was a player in warmer Japanese winters.
Published Giant clams may hold the answers to making solar energy more efficient
(via sciencedaily.com) Original source Solar panel and biorefinery designers could learn a thing or two from iridescent giant clams living near tropical coral reefs, according to a new study. This is because giant clams have precise geometries -- dynamic, vertical columns of photosynthetic receptors covered by a thin, light-scattering layer -- that may just make them the most efficient solar energy systems on Earth.
Published Neutrons on classically inexplicable paths
(via sciencedaily.com) Original source Is nature really as strange as quantum theory says -- or are there simpler explanations? New neutron measurements prove: It doesn't work without the strange properties of quantum theory.
Published Layers of carbonate provide insight into the world of the ancient Romans
(via sciencedaily.com) Original source Archaeologists face a major challenge when they intend to acquire information about buildings or facilities of which only ruins remain. This was a particular challenge for the remnants of the Roman water mills in Barbegal in Southern France, dating back to the 2nd century CE. This unique industrial complex consisted of 16 water wheels placed in parallel rows. Little could at first be deduced about the site from these now scant ruins -- except that the wheels were supplied by an aqueduct that brought water from the surrounding hills. Researchers have now unraveled the history of the mill complex using calcium carbonate deposits that are now stored in the Archaeological Museum of Arles. These deposits had formed towards the end of the roughly 100-year operational life of the Barbegal water mills on the sides and base of the wooden supply system that conveyed the water to the wheels.
