Published Microalgae with unusual cell biology



A globally distributed single-celled organism that occurs in harmful algal blooms has been found to exhibit an unusual organisation of photosynthesis. Researchers have taken a closer look at the unusual cell biology of the species Prorocentrum cordatum from the group of dinoflagellates. The results of their study could help to better understand the role of the species in the environment and the increased occurrence of algal blooms at higher water temperatures.
Published Plant Lavender, Marjoram and Ivy on your green wall to clean up the air



Green walls can strip pollution from the air -- and some plants do it better than others, according to new research. Researchers planted 10 species on a custom-built 1.4m green wall.
Published An inside look at Beech tree disease



A new study found differences at the cellular level of leaves from infected Beech trees -- variations that may account for tree mortality.
Published An evolutionary mystery 125 million years in the making



Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published Photosynthetic secrets come to light



Secrets of photosynthesis have been discovered at atomic level, shedding important new light on this plant super-power that greened the earth more than a billion years ago.
Published In wake of powerful cyclone, remarkable recovery of Pacific island's forests



After one of the most intense cyclones in world history tore through the Pacific island of Tanna in Vanuatu, new research showed the resilience of the island's forests.
Published Evolution-capable AI promotes green hydrogen production using more abundant chemical elements



A research team has developed an AI technique capable of expediting the identification of materials with desirable characteristics. Using this technique, the team was able to discover high-performance water electrolyzer electrode materials free of platinum-group elements -- substances previously thought to be indispensable in water electrolysis. These materials may be used to reduce the cost of large-scale production of green hydrogen -- a next-generation energy source.
Published Researchers create coating solution for safer food storage



Galvanized steel containers and surfaces are used for harvested produce because of their durability, strength and lower cost compared to stainless steel. However, bacteria residing in storage containers can cause corrosion. The new coating will reduce corrosion by at least 70 percent, researchers say.
Published Convergent evolution of algal CO2-fixing organelles



Researchers identified the proteins of a CO2-fixing organelle, namely, 'pyrenoid,' in the marine algal group Chlorarachniophyta and revealed various pyrenoid-associated proteins among algal groups, suggesting the independent evolution of pyrenoids in different algal groups.
Published AI-enabled atomic robotic probe to advance quantum material manufacturing



Scientists have pioneered a new methodology of fabricating carbon-based quantum materials at the atomic scale by integrating scanning probe microscopy techniques and deep neural networks. This breakthrough highlights the potential of implementing artificial intelligence at the sub-angstrom scale for enhanced control over atomic manufacturing, benefiting both fundamental research and future applications.
Published It's not only opposites that attract -- new study shows like-charged particles can come together



A study shows that similarly charged particles can sometimes attract, rather than repel. The team found that like-charged particles suspended in liquids can attract one another at long-range, depending on the solvent and the sign of the charge. The study has immediate implications for processes that involve interactions in solution across various length-scales, including self-assembly, crystallization, and phase separation.
Published Light into the darkness of photosynthesis



Researchers succeed at generating 3D visualizations of chloroplasts' copying machines.
Published Cyber-physical heating system may protect apple blossoms in orchards



Spring frosts can have devastating effects on apple production, and a warming climate may be causing trees to blossom early, making them more susceptible to the damaging effects of extreme cold events. Growers' attempts to prevent the flowers from freezing by attempting to heat the canopies of their orchards largely have been inefficient.
Published Refrigerate lettuce to reduce risk of E. coli contamination



Leafy green vegetables are important sources of dietary fiber and nutrients, but they can harbor harmful pathogens. In particular, lettuce has often been involved in outbreaks of foodborne illness across the U.S. A new study examines factors that affect E. coli contamination on five different leafy greens -- romaine lettuce, green-leaf lettuce, spinach, kale, and collards.
Published Better neutron mirrors can reveal the inner secrets of matter



Improved neutron mirrors can increase the efficiency of material analysis in neutron sources such as the ESS. The improved mirror has been developed by coating a silicon plate with extremely thin layers of iron and silicon mixed with boron carbide.
Published Lake ecosystems: Nitrogen has been underestimated



An ecological imbalance in a lake can usually be attributed to increased nutrient inputs. The result: increased phytoplankton growth, oxygen deficiency, toxic cyanobacterial blooms and fish kills. Until now, controls in lake management have focused primarily on phosphorus inputs to counteract this effect. Now, this dogma is shaken by a study showing that nitrogen is also a critical driver for phytoplankton growth in lakes worldwide.
Published Researchers improve the stability of perovskite solar cells



Perovskite solar cells are considered the strongest contender to replace silicon solar cells. While they achieve high power conversion energy, they also suffer from lead leakage and perovskite degradation due to moisture. Now scientists leverage the technique of interfacial passivation, where lead ions are bound by crown ether B18C6, obtaining 21.7% power conversion energy. The crown ether also resists degradation due to moisture for 300 hours at room temperature and 85% humidity.
Published Small dietary changes can cut your carbon footprint by 25%



New research provides compelling evidence that partially substituting animal with plant protein foods can increase life expectancy and decrease greenhouse gas emissions. Importantly, it also suggests that benefits depend on the type of animal protein being replaced. The study drew data from a national nutrition survey to analyze Canadians' dietary records. The study modeled partial replacements (25% and 50%) of either red and processed meat or dairy with plant protein foods like nuts, seeds, legumes, tofu, and fortified soy beverages, on a combination of nutrition, health, and climate outcomes.
Published A new plant's name that tells a story



A new species and genus of fairy lantern, tiny glass-like white plants that feed on fungi, has been discovered in Japan. In the country renowned for its extensive flora research, the discovery of a new plant genus is extremely rare and has not occurred in almost 100 years.
Published A bright idea for recycling rare-earth phosphors from used fluorescent bulbs



Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.
