Published AI reveals hidden traits about our planet's flora to help save species
(via sciencedaily.com) Original source Machine learning can help extract important information from the huge numbers of plant specimens stored in herbaria, say scientists.
Published New study reveals irrigation's mixed effects around the world
(via sciencedaily.com) Original source Trajectory of irrigation water use in many regions is unsustainable, but practice is vital in managing climate change and future agricultural development, researchers conclude.
Published Cryo conservation: A cool solution to saving species from extinction
(via sciencedaily.com) Original source In the face of the biodiversity crisis, and alarming data showing a 69% decline in global animal populations since 1970, researchers are banking on a cool solution to help save species from extinction. Much like egg-freezing is used to preserve human fertility options for a later date, the cryo-freezing of genetic samples taken from animals may play an essential role in curbing species extinctions. A new study sheds light on the immense potential of living cell banks, also known as cryobanks, to contribute to global conservation priorities.
Published Climate action plans mobilize limited urban change, researchers report
(via sciencedaily.com) Original source The Intergovernmental Panel on Climate Change Fifth Assessment Report (AR5), released just prior to an international climate convention in 2015, explicitly stated that human-caused greenhouse gas emissions were the highest in history, with clear and widespread impacts on the climate system. Since then, hundreds of cities across the world have published their own climate action plans (CAPs), detailing how their urban areas will handle climate change. How do the plans stack up against one another and against the recommended guidelines established by the United Nations-Habitat Guiding Principles for City Climate Action Planning?
Published A Tongan volcano plume produced the most intense lightning rates ever detected
(via sciencedaily.com) Original source New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.
Published Clean, sustainable fuels made 'from thin air' and plastic waste
(via sciencedaily.com) Original source Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.
Published Researchers want drivers to see clearly on the road
(via sciencedaily.com) Original source Every year, sun glare contributes to around 3,000 crashes in the United States. Researchers are helping to mitigate this problem by examining what drivers are likely to do when faced with sun glare.
Published To boost supply chains, scientists are looking at ways to recover valuable materials from water
(via sciencedaily.com) Original source Researchers are exploring the different ways of harvesting materials from water.
Published From cross to self-pollination
(via sciencedaily.com) Original source Biologists provide evidence for an alternative genetic mechanism that can lead to plants becoming self-pollinators.
Published How fungus farming ants keep their gardens healthy
(via sciencedaily.com) Original source 'Weed early and often' is the key to a productive garden. Interestingly, certain species of ants are also avid gardeners, a practice they've refined over 50 million years. They too weed their underground fungus gardens, but how they know what to weed out has been a mystery. Now, a multidisciplinary team of scientists report how ants distinguish the good fungus from the bad.
Published Study finds combustion from gas stoves can raise indoor levels of chemical linked to a higher risk of blood cell cancers
(via sciencedaily.com) Original source About 47 million homes use natural gas or propane-burning cooktops and ovens. Researchers found that cooking with gas stoves can raise indoor levels of the carcinogen benzene above those found in secondhand smoke.
Published Fossil study sheds light on famous spirals found in nature
(via sciencedaily.com) Original source A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in plants.
Published Navigating underground with cosmic-ray muons
(via sciencedaily.com) Original source Superfast, subatomic-sized particles called muons have been used to wirelessly navigate underground in a reportedly world first. By using muon-detecting ground stations synchronized with an underground muon-detecting receiver, researchers were able to calculate the receiver's position in the basement of a six-story building. As GPS cannot penetrate rock or water, this new technology could be used in future search and rescue efforts, to monitor undersea volcanoes, and guide autonomous vehicles underground and underwater.
Published Change food choices to increase chances of tackling global warming
(via sciencedaily.com) Original source Action to protect the planet against the impact of climate change will fall short unless we reduce greenhouse gas (GHG) emissions from the global food system, which now makes up a third of human-made GHG emissions, a new study reveals.
Published How will a warming world impact the Earth's ability to offset our carbon emissions?
(via sciencedaily.com) Original source New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.
Published We've pumped so much groundwater that we've nudged Earth's spin
(via sciencedaily.com) Original source By pumping water out of the ground and moving it elsewhere, humans have shifted such a large mass of water that the Earth tilted nearly 80 centimeters (31.5 inches) east between 1993 and 2010 alone, according to a new study.
Published This salty gel could harvest water from desert air
(via sciencedaily.com) Original source Engineers synthesized a superabsorbent material that can soak up a record amount of moisture from the air, even in desert-like conditions.
Published Genome editing used to create disease resistant rice
(via sciencedaily.com) Original source Researchers have used the genome-editing tool CRISPR-Cas to create disease resistant rice plants, according to a new study. Small-scale field trials in China show that the newly created rice variety exhibited both high yields and resistance to the fungus that causes a serious disease called rice blast.
Published Cleaner air with a cold catalytic converter
(via sciencedaily.com) Original source Although passenger vehicle catalytic converters have been mandatory for over 30 years, there is still plenty of room for improvement. For instance, they only work correctly when the engine is sufficiently hot, which is not always the case, especially with hybrid vehicles. Researchers have now developed an improved catalyst that can properly purify exhaust gases even at room temperature.
Published 10-year countdown to sea-ice-free Arctic
(via sciencedaily.com) Original source Research team predicts Arctic without ice by the end of 2030s if current increasing rate of greenhouse gas emission continues.
