Published Photosynthetic secrets come to light
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 AI outperforms humans in standardized tests of creative potential
(via sciencedaily.com) Original source In a recent study, 151 human participants were pitted against ChatGPT-4 in three tests designed to measure divergent thinking, which is considered to be an indicator of creative thought.
Published Convergent evolution of algal CO2-fixing organelles
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Light into the darkness of photosynthesis
(via sciencedaily.com) Original source Researchers succeed at generating 3D visualizations of chloroplasts' copying machines.
Published Cyber-physical heating system may protect apple blossoms in orchards
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Building bionic jellyfish for ocean exploration
(via sciencedaily.com) Original source Researchers show how biohybrid robots based on jellyfish could be used to gather climate science data from deep in the Earth's oceans.
Published Lake ecosystems: Nitrogen has been underestimated
(via sciencedaily.com) Original source 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 Small dietary changes can cut your carbon footprint by 25%
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 New AI model could streamline operations in a robotic warehouse
(via sciencedaily.com) Original source Researchers applied deep-learning approaches from vehicle routing to streamline planning trajectories for robots in an e-commerce warehouse. Their method breaks the problem down into smaller chunks and then predicts the best chunks to solve with traditional algorithms.
Published Creepy crawlies protect apples when flowers are planted on farms
(via sciencedaily.com) Original source Bugs including hoverflies, lacewings and ladybirds play an important role in keeping Britain's apples healthy, a new study has shown.
Published First metamaterial developed to enable real-time shape and property control
(via sciencedaily.com) Original source Engineers have unveiled an encodable multifunctional material that can dynamically tune its shape and mechanical properties in real time.
Published Walleye struggle with changes to timing of spring thaw
(via sciencedaily.com) Original source Walleye are one of the most sought-after species in freshwater sportfishing, a delicacy on Midwestern menus and a critically important part of the culture of many Indigenous communities. They are also struggling to survive in the warming waters of the Midwestern United States and Canada. According to a new study, part of the problem is that walleye are creatures of habit, and the seasons -- especially winter -- are changing so fast that this iconic species of freshwater fish can't keep up.
Published Low-Temperature Plasma used to remove E. coli from hydroponically grown crops
(via sciencedaily.com) Original source In a new study, a team sterilized a hydroponic nutrient solution using low-temperature plasma generated from electricity and the oxygen in the atmosphere. This new sterilization technique may allow farmers to grow crops without the use of chemical pesticides, representing an important advance in agricultural technology for sustainable crop production.
Published Scientists use blue-green algae as a surrogate mother for 'meat-like' proteins
(via sciencedaily.com) Original source Researchers have not only succeeded in using blue-green algae as a surrogate mother for a new protein -- they have even coaxed the microalgae to produce 'meat fiber-like' protein strands. The achievement may be the key to sustainable foods that have both the 'right' texture and require minimal processing.
Published Common plant could help reduce food insecurity
(via sciencedaily.com) Original source An often-overlooked water plant that can double its biomass in two days, capture nitrogen from the air -- making it a valuable green fertilizer -- and be fed to poultry and livestock could serve as life-saving food for humans in the event of a catastrophe or disaster, a new study suggests.
Published Biomolecular condensates -- regulatory hubs for plant iron supply
(via sciencedaily.com) Original source Iron is a micronutrient for plants. Biologists now show that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light -- an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into 'biomolecular condensates' in the cell nucleus shortly after this exposure.
