Published Cheap and efficient catalyst could boost renewable energy storage


Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published Crucial third clue to finding new diamond deposits


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 Remote work can slash your carbon footprint -- if done right



Remote workers can have a 54% lower carbon footprint compared with onsite workers, according to a new study, with lifestyle choices and work arrangements playing an essential role in determining the environmental benefits of remote and hybrid work.
Published New findings suggest Moon may have less water than previously thought


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 Study finds significant chemical exposures in women with cancer



Exposure to endocrine-disrupting chemicals like PFAS and phenols are implicated in hormone-mediated cancers of the breast, ovaries, skin and uterus. To learn more about the environmental exposures experienced by women who developed these cancers, researchers analyzed data from NHANES and found that women who reported having cancer had significantly higher levels of these chemicals in their bodies.
Published What is the carbon footprint of a hospital bed?



Researchers completed an assessment of a hospital to reveal its total environmental footprint and specific carbon emission hotspots.
Published Brilliant galaxies of early universe


Scientists have used data from the James Webb Space Telescope (JWST) as part of the Cosmic Evolution Early Release Science (CEERS) Survey to change the way we think about the universe and its distant galaxies. Astronomers authored a paper confirming very bright galaxies in the early universe, while also disproving the identification of what would have been the most distant galaxy ever found.
Published Polar experiments reveal seasonal cycle in Antarctic sea ice algae


Results provide the first measurements of how sea-ice algae and other single-celled life adjust to the dramatic seasonal rhythms in the Southern Ocean. The results provide clues to what might happen as this ecosystem shifts under climate change.
Published Snaps supersonic outflow of young star


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 Genetically modified bacteria break down plastics in saltwater



Researchers have genetically engineered a marine microorganism to break down plastic in salt water. Specifically, the modified organism can break down polyethylene terephthalate (PET), a plastic used in everything from water bottles to clothing that is a significant contributor to microplastic pollution in oceans.
Published Electrons from Earth may be forming water on the Moon


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


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


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


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


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


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


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 Matter comprises of 31% of the total amount of matter and energy in the universe


One of the most interesting and important questions in cosmology is, 'How much matter exists in the universe?' An international team has now succeeded in measuring the total amount of matter for the second time. The team determined that matter makes up 31% of the total amount of matter and energy in the universe, with the remainder consisting of dark energy.
Published Pixel-by-pixel analysis yields insights into lithium-ion batteries


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 Discovery of two potential Polar Ring galaxies suggests these stunning rare clusters might be more common than previously believed


These new detections suggest polar ring galaxies might be more common than previously believed.
