Published From pets to pests: How domestic rabbits survive the wilderness
(via sciencedaily.com) Original source How do rabbits go from fluffy pets to marauding invaders? Rabbits have colonized countries worldwide, often with dire economic and ecological consequences, but their secret has until now been a mystery. Biologists sequenced the genomes of nearly 300 rabbits from across three continents to unveil the key genetic changes that make these animals master colonizers.
Published Antarctica vulnerable to invasive species hitching rides on plastic and organic debris
(via sciencedaily.com) Original source A new study reveals how ocean biology and marine pollution can end up on Antarctica's shoreline.
Published Honey bees may play key role in spreading viruses to wild bumblebees
(via sciencedaily.com) Original source Honey bees may play a role in increasing virus levels in wild bumble bees each spring, according to researchers who analyzed seasonal trends of parasite and virus transmission in bees.
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 'Masters of shape-shifting': How darkling beetles conquered the world
(via sciencedaily.com) Original source Large-scale genomic analysis of darkling beetles, a hyper-diverse insect group of more than 30,000 species worldwide, rolls back the curtain on a 150-million-year evolutionary tale of one of Earth's most ecologically important yet inconspicuous creatures, according to new research.
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 The bee's knees: New tests created to find fake honey
(via sciencedaily.com) Original source Researchers have developed new ways to detect sugar syrup adulteration in honey, paving the way for fast and accurate tests to discover fake products.
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 Historic map reveals how mussel farm is bringing shellfish reefs back to the seabed
(via sciencedaily.com) Original source New analysis has shown that the UK's first large scale offshore mussel farm might in fact serve as a form of restoration rather than creating habitats never seen in the area before. A map dating from 1871 shows a large area of the seabed -- stretching from Torquay in the west and beyond Lyme Regis to the east -- as being home to 'rich shell beds'. The region has now been transformed from muddy sediment with limited biodiversity into reefs, which research has shown have the potential to benefit a number of commercial fish and crustacean species and the ecosystem more generally.
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 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 Scientists condition crocodiles to avoid killer cane toads
(via sciencedaily.com) Original source Scientists have trialled a new way to protect freshwater crocodiles from deadly invasive cane toads spreading across northern Australia.
Published Study reveals urban trees suffer more from heat waves and drought than their rural counterparts
(via sciencedaily.com) Original source A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.
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 Turning unused signals such as Wi-Fi into energy for electronics
(via sciencedaily.com) Original source We are constantly surrounded by electromagnetic waves such as Wi-Fi. Researchers tested a device to convert this ambient energy into energy for electronic devices.
