Published Free electric vehicle charging at work? It's possible with optimum solar



The global surge in electric vehicle sales has prompted an Australian university to explore how it could offer free or nominal EV charging facilities to staff and students by optimizing its solar PV system and minimizing workplace electricity costs.
Published Best areas for rewilding European bison



Simulations integrate historical records, fossils, and ancient DNA to reveal why the European bison nearly went extinct, and pinpoint optimal areas for conservation. Since the near-extinction of the European bison, enormous conservation efforts have helped to restore wild populations, and its numbers are on the rise. However, the study authors argue that ensuring the species's long-term protection and recovery requires understanding why they nearly went extinct in the first place. 'Our study also suggests areas where rewilding attempts are most likely to be successful,' said lead author July Pilowsky, currently a disease ecologist at Cary Institute of Ecosystem Studies. Pilowsky completed the research while working on their PhD at University of Adelaide and University of Copenhagen.
Published New study sheds light on how much methane is produced from Arctic lakes and wetlands



New study looked at lakes in the Arctic, including those at Alaska's Yukon Flats National Wildlife Refuge, to shed light on how much methane is produced from Arctic lakes and wetlands. Small unmapped lakes in the Arctic are far less abundant than previously thought, greatly reducing the cumulative methane emissions they were thought to contribute to Earth's atmosphere.
Published This Japanese 'dragon' terrorized ancient seas



Researchers have described a Japanese mosasaur the size of a great white shark that terrorized Pacific seas 72 million years ago. The mosasaur was named for the place where it was found, Wakayama Prefecture. Researchers call it the Wakayama Soryu, which means blue dragon.
Published Underwater architects: The 'burrowing effect' of foraminifera on marine environments



Impact of single-cell organisms on sediment oxygen levels and bacterial diversity measured for the first time.
Published New geophysical technique enhances imaging of fluid-filled rocks finding connections with microearthquakes



Scientists have recently introduced a new method called ambient noise differential adjoint tomography, which allows researchers to visualise rocks with fluids better, leading to potential advancements in the discovery of water and oil resources, as well as applications in urban geologic hazard and early warning systems for tsunamis and the understanding of the water cycle.
Published Climate change will increase wildfire risk and lengthen fire seasons



Wildfires are some of the most destructive natural disasters in the country, threatening lives, destroying homes and infrastructure, and creating air pollution. In order to properly forecast and manage wildfires, managers need to understand wildfire risk and allocate resources accordingly.
Published Coral reefs in peril from record-breaking ocean heat



Record breaking marine heatwaves will cause devastating mass coral bleaching worldwide in the next few years, according to a coral reef scientist.
Published Adapting to hypoxia: Zooplankton influence the efficiency of the biological carbon pump in the Humboldt Current off Peru



Marine organisms play a crucial role in the global carbon cycle. Phytoplankton absorb carbon dioxide from the atmosphere and sequester it in organic matter that sinks to the deep ocean where it can be stored for long periods of time. Until now, this process -- the biological carbon pump -- was thought to be particularly efficient in oxygen-poor areas. A new study suggests that the influence of certain zooplankton species on the biological carbon pump has been underestimated.
Published Molecular fossils shed light on ancient life



Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Published It turns out, this fossil 'plant' is really a fossil baby turtle



Researchers re-examined a plant fossil found decades ago in Colombia and realized that it wasn't a plant at all: it's a fossilized baby turtle. It's a rare find, because juvenile turtles' shells are soft and often don't fossilize well.
Published Geoscientists map changes in atmospheric carbon dioxide over past 66 million years



An international consortium of geoscientists has reconstructed atmosphereric levels of carbon dioxide going back 66 million years using proxies in the geoloogical record. Today's concenteration, 420 parts per million, is higher than it's ever been in 14 million years.
Published Protected areas in Thailand are at a higher risk of forest fires when located away from indigenous communities



Research has found that national parks and protected areas are at a higher risk of forest fires when located farther away from indigenous communities. Based on the analysis of satellite images from Thailand and case studies from other Southeast Asian countries, the research demonstrates that policymakers can achieve improvements in forest health by working collaboratively with indigenous communities. Involving communities results in reduction of forest fires and air pollution.
Published Baboons in captivity in Ancient Egypt: insights from collection of mummies



Baboons were raised in captivity before being mummified in Ancient Egyptian sites, according to a new study.
Published Climate change shown to cause methane to be released from the deep ocean



New research has shown that fire-ice -- frozen methane which is trapped as a solid under our oceans -- is vulnerable to melting due to climate change and could be released into the sea.
Published Greenhouse gases in oceans are altered by climate change impact on microbes



The ocean is a global life-support system, and climate change causes such as ocean warming, acidification, deoxygenation, and nitrogen-deposition alter the delicate microbial population in oceans. The marine microbial community plays an important role in the production of greenhouse gases like nitrous oxide and methane. Scientists have explored the climate change impact on marine microbes. Their research helps raise awareness about climate change severity and the importance of ocean resources.
Published The ocean may be storing more carbon than estimated in earlier studies



The ocean's capacity to store atmospheric carbon dioxide is some 20% greater than the estimates contained in the latest IPCC report. Scientists looked at the role played by plankton in the natural transport of carbon from surface waters down to the seabed. Plankton gobble up carbon dioxide and, as they grow, convert it into organic tissue via photosynthesis.
Published Plant nurseries are exacerbating the climate-driven spread of 80% of invasive species



Researchers have provided detailed maps of how 144 common invasive plants species will react to 2° Celsius of climate change in the eastern U.S., as well as the role that garden centers currently play in seeding future invasions.
Published Fossil CO2 emissions at record high in 2023



Global carbon emissions from fossil fuels have risen again in 2023 -- reaching record levels, according to new research.
Published Deep sea sensor reveals that corals produce reactive oxygen species



A new sensor on the submersible Alvin discovered reactive oxygen species for the first time in deep-sea corals, broadening our understanding of fundamental coral physiology.
