Published Researchers discover a new species of larger benthic foraminifer from the Ryukyu Islands



An international group of researchers have discovered a previously unknown species of large foraminifer, shedding new light on the ecological evolution and biodiversity of coral reefs in the Ryukyu Islands.
Published Gene required for root hair growth, nitrate foraging found in grasses



Scientists have found a plant gene that drives the growth of root hairs, the tiny structures that help plants find water and nutrients in the soil. The gene, dubbed 'BUZZ,' causes faster-growing, denser webs of roots and may also determine how plants find and use nitrates, a prime source of nitrogen essential to plant growth. Nitrates are also used in fertilizers that can pollute the environment as runoff, and this genetic discovery could ultimately help plant scientists find ways to grow crops more sustainably.
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 Tiny sea creatures reveal the ancient origins of neurons



A new study sheds new light on the origins of modern brain cells. Researchers find evidence that specialized secretory cells found in placozoans, tiny sea creatures the size of a grain of sand, have many similarities to the neuron, such as the genes required to create a partial synapse. From an evolutionary point of view, early neurons might have started as something like these cells, eventually gaining the ability to create a complete synapse, form axons and dendrites and create ion channels that generate fast electrical signals -- innovations which gave rise to the neuron in more complex animals such as jellyfish. Though the complete story of how the first neuron appeared remains to be told, the study demonstrates that the basic building blocks for our brain cells were forming in the ancestors of placozoans grazing inconspicuously in the shallow seas of Earth around 800 million years ago.
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 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 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 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 Rivers are rapidly warming, losing oxygen; aquatic life at risk



Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.
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 find good places to grow long-spined sea urchins, a starting point to restore 'the lawn mowers of the reefs'


Scientists are trying to raise as many urchins as possible because they eat algae that could otherwise smother reef ecosystems and kill corals. Researchers have identified algae on which larval sea urchins grow into juveniles in a lab setting.
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 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 Freshwater connectivity can transport environmental DNA through the landscape


A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
