Published Study examines tree adaptability to climate change



Many trees could expand their ranges by more than 25 percent based on their potential temperature tolerances.
Published Building materials for water-rich planets in the early solar system



Age data for certain classes of meteorite have made it possible to gain new findings on the origin of small water-rich astronomical bodies in the early solar system. These planetesimals continually supplied building materials for planets -- also for the Earth, whose original material contained little water. The Earth received its actual water through planetesimals, which emerged at low temperatures in the outer solar system, as shown by computational models carried out by an international research teach with participation by earth scientists.
Published First local extinction in the US due to sea level rise, study suggests



The United States has lost its only stand of the massive Key Largo tree cactus in what researchers believe is the first local extinction of a species caused by sea level rise in the country.
Published How a plant app helps identify the consequences of climate change



A research team has developed an algorithm that analyses observational data from a plant identification app. The novel approach can be used to derive ecological patterns that could provide valuable information about the effects of climate change on plants.
Published Wastewater is a viable medium for growing lettuce in hydroponic systems



Urban agriculture has the potential to improve food security through local, efficient, and sustainable food production. Examples of urban food systems include hydroponics, where plants grow in a nutrient solution without soil, and aquaponics, which combines hydroponics with raising fish in tanks. A new study examines the use of aquaponics wastewater as a growth medium for lettuce in a hydroponic system. This practice can potentially create a circular ecosystem for organic waste recycling and food production.
Published Climate change drives tree species towards colder, wetter regions



Climate change is likely to drive tree species towards colder and wetter regions.
Published Mechanism of bio-inspired control of liquid flow



The more we discover about the natural world, the more we find that nature is the greatest engineer. Past research implied that liquids can only be transported in fixed direction on species with specific liquid communication properties and cannot switch the transport direction. Recently, researchers have shown that an African plant controls water movement in a previously unknown way -- and this could inspire breakthroughs in a range of technologies in fluid dynamics and nature-inspired materials, including applications that require multistep and repeated reactions, such as microassays, medical diagnosis and solar desalination etc.
Published Study illuminates cues algae use to 'listen' to their environment



New research shows how a small group of single-celled algae are able to use chemical cues to communicate stress information. Understanding this ability, once thought unique to plants, helps illuminate the complex evolutionary history of plants and algae.
Published Organic material from Mars reveals the likely origin of life's building blocks



Two samples from Mars together deliver clear evidence of the origin of Martian organic material. The study presents solid evidence for a prediction made over a decade ago that could be key to understanding how organic molecules, the foundation of life, were first formed here on Earth.
Published Choose where to plant energy crops wisely to minimise loss of biodiversity



In the fight to protect biodiversity and limit climate change, the world will reap what it sows.
Published Sixty-million-year-old grape seeds reveal how the death of the dinosaurs may have paved the way for grapes to spread



Scientists discovered the oldest fossil grapes in the Western Hemisphere, which help show how after the death of the dinosaurs, grapes spread across the world.
Published This desert moss has the potential to grow on Mars



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 Investigating newly discovered hydrothermal vents at depths of 3,000 meters off Svalbard



Hydrothermal vents can be found around the world at the junctions of drifting tectonic plates. But there are many hydrothermal fields still to be discovered. During a 2022 expedition of the MARIA S. MERIAN, the first field of hydrothermal vents on the 500-kilometer-long Knipovich Ridge off the coast of Svalbard was discovered.
Published Groundbreaking discovery: Zinc can make crop yields more climate-resilient



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 Why the harsh Snowball Earth kick-started our earliest multicellular ancestors



Why did multicellularity arise? Solving that mystery may help pinpoint life on other planets and explain the vast diversity and complexity seen on Earth today, from sea sponges to redwoods to human society. A new article shows how specific physical conditions -- especially ocean viscosity and resource deprivation -- during the global glaciation period known as Snowball Earth could have driven eukaryotes to turn multicellular.
Published Scientists discover genetic 'off switch' in legume plants that limits biological ability to source nutrients



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



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 Iceland's volcano eruptions may last decades



Scientists predict from geochemical data that Iceland is entering a new volcanic era that will last for decades, possibly centuries. Under an hour's drive from the country's capital city, the ongoing eruptions pose considerable risks for economic disruption, and they leave evacuated communities uncertain of a possible return.
Published Removal of excess chloride ions by plants when subjected to salt stress



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



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.
