Published Scientists develop method to detect deadly infectious diseases
(via sciencedaily.com) Researchers have developed a way of detecting the early onset of deadly infectious diseases using a test so ultrasensitive that it could someday revolutionize medical approaches to epidemics. The test is an electronic sensor contained within a computer chip. It employs nanoballs -- microscopic spherical clumps made of tinier particles of genetic material -- and combines that technology with advanced electronics.
Published Crucial third clue to finding new diamond deposits
(via sciencedaily.com) Researchers studying diamond-rich rocks from Western Australia's Argyle volcano have identified the missing third key ingredient needed to bring valuable pink diamonds to the Earth's surface where they can be mined, which could greatly help in the global hunt for new deposits.
Published New findings suggest Moon may have less water than previously thought
(via sciencedaily.com) A team recently calculated that most of the Moon's permanently shadowed regions (PSRs) are at most around 3.4 billion years old and can contain relatively young deposits of water ice. Water resources are considered key for sustainable exploration of the Moon and beyond, but these findings suggest that current estimates for cold-trapped ices are too high.
Published Engineered compound shows promise in preventing bone loss in space
(via sciencedaily.com) Original source Mice treated aboard the International Space Station showed significantly reduced bone loss.
Published Snaps supersonic outflow of young star
(via sciencedaily.com) Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. This image of HH 211 from NASA's James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile analog of our Sun when it was no more than a few tens of thousands of years old and with a mass only 8% of the present-day Sun (it will eventually grow into a star like the Sun).
Published Carbon atoms coming together in space
(via sciencedaily.com) Original source Lab-based studies reveal how carbon atoms diffuse on the surface of interstellar ice grains to form complex organic compounds, crucial to reveal the chemical complexity in the universe.
Published Electrons from Earth may be forming water on the Moon
(via sciencedaily.com) Planetary scientists have discovered that high energy electrons in Earth's plasma sheet are contributing to weathering processes on the Moon's surface and, importantly, the electrons may have aided the formation of water on the lunar surface.
Published Making hydrogen from waste plastic could pay for itself
(via sciencedaily.com) Researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that generates graphene as a by-product, which could help offset production costs.
Published Researchers make strides in harnessing low-grade heat for efficient energy conversion
(via sciencedaily.com) A research team has achieved significant breakthroughs in harnessing low-grade heat sources (<100 °C) for efficient energy conversion.
Published Breakthrough: Highly efficient electrocatalyst for clean energy
(via sciencedaily.com) A research team has achieved a groundbreaking advancement in nanomaterials by successfully developing a highly efficient electrocatalyst which can enhance the generation of hydrogen significantly through electrochemical water splitting. This major breakthrough has great application potential for the clean energy industry.
Published Electrifying vehicles in Chicago would save lives, reduce pollution inequities
(via sciencedaily.com) If the Chicago region replaced 30% of all on-road combustion-engine vehicles -- including motorcycles, passenger cars and trucks, buses, refuse trucks and short- and long-haul trucks -- with electric versions, it would annually save more than 1,000 lives and over $10 billion, according to a new study.
Published Scientists invent a bright way to upcycle plastics into liquids that can store hydrogen energy
(via sciencedaily.com) Scientists have created a process that can upcycle most plastics into chemicals useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all at room temperature. The new process is very energy-efficient and can be easily powered by renewable energy in the future, unlike other heat-driven recycling processes like pyrolysis. Currently, only nine per cent of plastics globally are recycled and the rest are typically discarded in landfills or incinerated.
Published Some spiders can transfer mercury contamination to land animals
(via sciencedaily.com) Sitting calmly in their webs, many spiders wait for prey to come to them. Arachnids along lakes and rivers eat aquatic insects, such as dragonflies. But, when these insects live in mercury-contaminated waterways, they can pass the metal along to the spiders that feed on them. Now, researchers have demonstrated how some shoreline spiders can move mercury contamination from riverbeds up the food chain to land animals.
Published Pixel-by-pixel analysis yields insights into lithium-ion batteries
(via sciencedaily.com) By mining X-ray images, researchers have made significant new discoveries about the reactivity of lithium iron phosphate, a material used in batteries for electric cars and in other rechargeable batteries.
Published Chemist uses nature as inspiration for a sustainable, affordable adhesive system
(via sciencedaily.com) A chemist drew inspiration from the natural world, from his experiences scuba diving to studying shellfish in his lab. He has developed a sustainable adhesive system -- an alternative to toxic, permanent, traditional adhesives.
Published Gotcha! New technology speeds up bacterial testing in food
(via sciencedaily.com) Researchers have developed a measurement technique that rapidly measures the number of viable bacteria in food products. They have succeeded in drastically reducing the inspection time from 2 days to about 1 hour. With this technology, it will be possible to confirm food safety before shipment from factories and prevent food poisoning.
Published Hot summer air turns into drinking water with new gel device
(via sciencedaily.com) Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.
Published Urban parks built on former waste incineration sites could be lead hotspots
(via sciencedaily.com) A new study finds that surface soil in parks and playgrounds built on former waste incineration and ash disposal sites may contain levels of lead exceeding EPA safety standards for areas where children play. The contamination, which can persist long after an incinerator is closed, stems from burning paint, pipes and other products that contained lead. Sites in hundreds of U.S. and Canadian cities could be contaminated. Increased monitoring is needed to pinpoint hotspots.
Published Researchers discover iron-targeting approaches to halt proliferation of cancer cells
(via sciencedaily.com) Researchers discovered a new class of iron-targeting compounds that hamper the proliferation of cultured malignant cells in a laboratory setting.
Published Important connectivity of metal oxides with hydrogen
(via sciencedaily.com) A recent article proposes a new way to understand how materials interact with hydrogen.
