Published A newly identified virus emerges from the deep



Marine virologists analyzed sediment from the Mariana Trench, the deepest place on Earth, and identified a new bacteriophage.
Published New Si-based photocatalyst enables efficient solar-driven hydrogen production and biomass refinery


A research team has achieved a significant breakthrough in the development of a hybrid silicon photocatalyst.
Published New research brings greater understanding of Asian winter monsoon



Scientists have discovered a new technique which will shed light on the phenomena of winter monsoons -- the heavy autumn and winter rainfalls which can cause floods and landslides across southeast Asia.
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 Laser-based ice-core sampling for studying climate change


Researchers have developed a new laser-based sampling system for studying the composition of ice cores taken from glaciers. The new system has a 3-mm depth-resolution and is expected to help reconstruct continuous annual temperature changes that occurred thousands to hundreds of thousands of years ago, which will help scientists understand climate change in the past and present.
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 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 Step change in upconversion the key to clean water, green energy and futuristic medicine


Achieving photochemical upconversion in a solid state is a step closer to reality, thanks to a new technique that could unlock vital innovations in renewable energy, water purification and advanced healthcare.
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 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 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 Ohio's droughts are worse than often recognized, study finds



A new type of analysis suggests that droughts in Ohio were more severe from 2000 to 2019 than standard measurements have suggested.
Published 100-year floods could occur yearly by end of 21st century



Most coastal communities will encounter '100-year floods' annually by the end of the century, even under a moderate scenario where carbon dioxide emissions peak by 2040, according to a new study. And as early as 2050, regions worldwide could experience 100-year floods every nine to fifteen years on average.
Published New research reveals why and when the Sahara Desert was green



A pioneering study has shed new light on North African humid periods that have occurred over the past 800,000 years and explains why the Sahara Desert was periodically green.
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.
Published New rivers in the North? Scientists identify how the dissection of Arctic landscapes is changing with accelerating climate change



New research shows that amplified global warming in the Canadian High Arctic drove a profound shift in the structure of a river network carved into a permafrost landscape in only 60 years.
