Published This desert moss has the potential to grow on Mars
(via sciencedaily.com) Original source The desert moss Syntrichia caninervis is a promising candidate for Mars colonization thanks to its extreme ability to tolerate harsh conditions lethal to most life forms. The moss is well known for its ability to tolerate drought conditions, but researchers now report that it can also survive freezing temperatures as low as 196 C, high levels of gamma radiation, and simulated Martian conditions involving these three stressors combined. In all cases, prior dehydration seemed to help the plants cope.
Published Groundbreaking discovery: Zinc can make crop yields more climate-resilient
(via sciencedaily.com) Original source Climate change, drought, increased temperature and other stressors challenge agricultural sustainability. Researchers have now made an unexpected discovery: zinc plays a pivotal role in the plant response to abiotic stress. This groundbreaking discovery not only sheds light on the intricate mechanisms of plant growth but also holds promise for revolutionizing crop resilience, especially in legume-based agriculture.
Published Scientists discover genetic 'off switch' in legume plants that limits biological ability to source nutrients
(via sciencedaily.com) Original source A genetic 'off switch' that shuts down the process in which legume plants convert atmospheric nitrogen into nutrients has been identified for the first time by a team of international scientists.
Published New tool enables faster, more cost-effective genome editing of traits to improve agriculture sustainability
(via sciencedaily.com) Original source New research had the goal of reducing the time and cost it takes to bring an improved crop to the marketplace to improve agriculture sustainability.
Published Removal of excess chloride ions by plants when subjected to salt stress
(via sciencedaily.com) Original source Researchers have discovered a salt adaptation mechanism in plants that facilitates chloride removal from the roots and enhancing salinity tolerance. A research team has uncovered a novel mechanism of plant adaptation to salt stress involving the NaCl-induced translocation of a specific chloride channel protein, AtCLCf.
Published New tomato, potato family tree shows that fruit color and size evolved together
(via sciencedaily.com) Original source A new family tree of the plant genus Solanum helps explain the striking diversity of their fruit color and size. This genus includes tomatoes, potatoes, eggplants, and other economically important plants.
Published Wild chimpanzees seek out medicinal plants to treat illness and injuries
(via sciencedaily.com) Original source Chimpanzees appear to consume plants with medicinal properties to treat their ailments, according to a new study.
Published Interaction with insects accelerates plant evolution
(via sciencedaily.com) Original source Researchers have discovered that plants benefit from a greater variety of interactions with pollinators and herbivores. Plants that are pollinated by insects and have to defend themselves against herbivores have evolved to be better adapted to different types of soil.
Published AI shows how field crops develop
(via sciencedaily.com) Original source Researchers developed software that can simulate the growth of field crops. To do this, they fed thousands of photos from field experiments into a learning algorithm. This enabled the algorithm to learn how to visualize the future development of cultivated plants based on a single initial image. Using the images created during this process, parameters such as leaf area or yield can be estimated accurately.
Published Can engineered plants help make baby formula as nutritious as breast milk?
(via sciencedaily.com) Original source New research may help close the nutrition gap between infant formula and human breast milk. The study shows how plants can be programmed to produce a diverse array of beneficial sugars found in human breast milk. The findings could lead to healthier and more affordable formula for babies, or more nutritious non-dairy plant milk for adults.
Published Pair plasmas found in deep space can now be generated in the lab
(via sciencedaily.com) Original source Researchers have experimentally generated high-density relativistic electron-positron pair-plasma beams by producing two to three orders of magnitude more pairs than previously reported.
Published Ancient Syrian diets resembled the modern 'Mediterranean diet'
(via sciencedaily.com) Original source Thousands of years ago, people in ancient Syria likely ate mostly grains, grapes, olives and a small amount of dairy and meat -- similar to today's 'Mediterranean diet,' according to a new study.
Published Metal alloys that can take the heat
(via sciencedaily.com) Original source Complex metal alloys enter a new era of predictive design for aerospace and other high-temperature applications.
Published Are plants intelligent? It depends on the definition
(via sciencedaily.com) Original source Goldenrod can perceive other plants nearby without ever touching them, by sensing far-red light ratios reflected off leaves. When goldenrod is eaten by herbivores, it adapts its response based on whether or not another plant is nearby. Is this kind of flexible, real-time, adaptive response a sign of intelligence in plants?
Published Scientists engineer yellow-seeded camelina with high oil output
(via sciencedaily.com) Original source Using tools of modern genetics, plant biochemists have produced a new high-yielding oilseed crop variety -- a yellow-seeded variety of Camelina sativa, a close relative of canola, that accumulates 21.4% more oil than ordinary camelina.
Published Soil bacteria respire more CO2 after sugar-free meals
(via sciencedaily.com) Original source Researchers tracked how plant matter moves through bacteria's metabolism. Microbes respire three times as much carbon dioxide (CO2) from non-sugar carbons from lignin compared to sugar from cellulose. Although microbes consume both types of plant matter at the same time, each type enters a different metabolic pathway. Findings could improve predictions of how climate-dependent changes in soil carbon types will affect microbial CO2 production.
Published New plasma escape mechanism could protect fusion vessels from excessive heat
(via sciencedaily.com) Original source The exhaust heat generated by a fusing plasma in a commercial-scale reactor may not be as damaging to the vessel's innards as once thought, according to new research about escaping plasma particles.
Published Algae offer real potential as a renewable electricity source
(via sciencedaily.com) Original source The need to transition away from fossil fuels to more sustainable energy production is critical. That's why a team of researchers is looking at a potential power source that not only produces no carbon emissions but removes carbon as it works: algae.
Published Fine-tuning leaf angle with CRISPR improves sugarcane yield
(via sciencedaily.com) Original source A CABBI research team has used CRISPR/Cas9 gene editing to optimize leaf angle in sugarcane, increasing the amount of sunlight it captures and the amount of biomass it produces.
Published Early life exposure to weed pollen could increase childhood asthma risk
(via sciencedaily.com) Original source A study has found children who are exposed to tree and weed pollen in urban environments are at increased risk of respiratory health problems, including asthma. While green areas in urban settings decrease exposure to air pollution, allow kids to be active, and offer positive contact to a diverse microbiota -- which in turn may help the positive development of a child's immune system -- they can also lead to the development of childhood asthma. Thankfully, trees can help mitigate this effect to some degree, thanks to their canopy.
