Published A leaky sink: Carbon emissions from forest soil will likely grow with rising temperatures
(via sciencedaily.com) Original source The soils of northern forests are key reservoirs that help keep the carbon dioxide that trees inhale and use for photosynthesis from making it back into the atmosphere.
Published Innovative field experiments shed light on biological clocks in nature
(via sciencedaily.com) Original source A new study has used a series of innovative field experiments to show how plants combine circadian clock signals with environmental cues under naturally fluctuating conditions.
Published Human-wildlife overlap expected to increase across more than half of land on Earth by 2070
(via sciencedaily.com) Original source Human-wildlife overlap could increase across about 57% of the global lands by 2070 and could lead to more conflict between people and animals. Understanding where the overlap is likely to occur -- and which animals are likely to interact with humans in specific areas -- will be crucial information for urban planners, conservationists and countries that have pledged international conservation commitments.
Published Pilot study uses recycled glass to grow plants for salsa ingredients
(via sciencedaily.com) Original source Tortilla chips and fresh salsa are tasty, but they could be even more appealing if you grow the ingredients yourself. Now, researchers report that some salsa ingredients -- cilantro, bell pepper and jalapeno -- can be more sustainably cultivated with recycled glass. Their pilot study found that partially substituting soil in a planter with recycled glass fragments speeds up plant development and reduces unwanted fungal growth.
Published Dormant capacity reserve in lithium-ion batteries detected
(via sciencedaily.com) Original source Lithium iron phosphate is one of the most important materials for batteries in electric cars, stationary energy storage systems and tools. It has a long service life, is comparatively inexpensive and does not tend to spontaneously combust. Energy density is also making progress. However, experts are still puzzled as to why lithium iron phosphate batteries undercut their theoretical electricity storage capacity by up to 25 per cent in practice.
Published Researchers uncover the secrets of 'plant puberty'
(via sciencedaily.com) Original source Researchers have identified the genetic changes linked to why plants go through a developmental change similar to 'puberty' at different rates, a discovery which could lead to better crop nutrition.
Published Development of a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries
(via sciencedaily.com) Original source Scientists have developed a model capable of predicting the cycle lives of high-energy-density lithium-metal batteries by applying machine learning methods to battery performance data. The model proved able to accurately estimate batteries' longevity by analyzing their charge, discharge and voltage relaxation process data without relying on any assumption about specific battery degradation mechanisms. The technique is expected to be useful in improving the safety and reliability of devices powered by lithium-metal batteries.
Published Will climate change lead to the extinction of a newly discovered tarantula species?
(via sciencedaily.com) Original source Biologists have discovered a new species of tarantula from the Madrean Sky Island biodiversity hotspot in southeastern Arizona. This remarkable new species is endemic to the Chiricahua Mountains and is predominately distributed in mid- to high-elevation forests, which are increasingly threatened due to climate change.
Published Engineers design tiny batteries for powering cell-sized robots
(via sciencedaily.com) Original source A zinc-air microbattery could enable the deployment of cell-sized, autonomous robots for drug delivery within in the human body, as well as other applications such as locating leaks in gas pipelines.
Published Research provides a roadmap for improving electrochemical performance
(via sciencedaily.com) Original source A study expands understanding on how electrons move through the conductive parts of complex fluids found in electrochemical devices such as batteries. This work can help overcome existing knowledge gaps for engineers seeking to improve the performance of these devices.
Published As human activities expand in Antarctica, scientists identify crucial conservation sites
(via sciencedaily.com) Original source Establishing Key Biodiversity Areas in the Southern Ocean will be vital for safeguarding the ecosystem from the impact of human activities, researchers say.
Published Why do plants wiggle? New study provides answers
(via sciencedaily.com) Original source Decades after his voyage on the HMS Beagle, Charles Darwin became fascinated by why plants move as they grow -- spinning and twisting into corkscrews. Now, more than 150 years later, a new study may have solved the riddle.
Published A method that paves the way for improved fuel cell vehicles
(via sciencedaily.com) Original source More efficient and longer-lasting fuel cells are essential for fuel cell-powered heavy-duty hydrogen vehicles to be an alternative to combustion fuelled counterparts. Researchers have developed an innovative method to study and understand how parts of fuel cells degrade over time. This is an important step towards the improved performance of fuel cells and them becoming commercially successful.
Published Ecologists put an insect group on century-old map of biodiversity
(via sciencedaily.com) Original source The distribution of species around the globe is not a random process but an outcome resulting from several evolutionary mechanisms as well as past and current environmental limitations. As a result, since the mid-19th century, biologists have identified several main regions, called biogeographic realms, that depict these large ensembles of species around the world. These biogeographic realms represent one of the most fundamental descriptions of biodiversity on Earth and are commonly used in various fields of biology.
Published Giant fossil seeds from Borneo record ancient plant migration
(via sciencedaily.com) Original source Ancient fossil beans about the size of modern limes, and among the largest seeds in the fossil record, may provide new insight into the evolution of today's diverse Southeast Asian and Australian rainforests, according to researchers who identified the plants.
Published Forest restoration can boost people, nature and climate simultaneously
(via sciencedaily.com) Original source Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
Published Glossy black-cockatoos prefer the fruits of ancient rocks
(via sciencedaily.com) Original source New research has shown that glossy black-cockatoos prefer to feed from trees growing in acidic soils.
Published Nature at risk in the hunt for the perfect selfie
(via sciencedaily.com) Original source The need for a dramatic selfie or the perfect landscape photo is proving detrimental to nature, a new research collaboration has found.
Published Unlocking the secrets of salt stress tolerance in wild tomatoes
(via sciencedaily.com) Original source As our climate changes and soil salinity increases in many agricultural areas, finding crops that can thrive in these challenging conditions is crucial. Cultivated tomatoes, while delicious, often struggle in salty soils. Their wild cousins, however, have evolved to survive in diverse and often harsh environments. A recent study delved into the genetic treasure trove of wild tomatoes to uncover secrets of salt tolerance that could be used to develop resilient crop varieties.
Published Discovering how plants make life-and-death decisions
(via sciencedaily.com) Original source Researchers have discovered two proteins that work in tandem to control an important response to cell stress.
