Published Key moment in the evolution of life on Earth captured in fossils



New research has precisely dated some of the oldest fossils of complex multicellular life in the world, helping to track a pivotal moment in the history of Earth when the seas began teeming with new lifeforms -- after four billion years of containing only single-celled microbes.
Published How tidal range electricity generation can protect coastal areas from flooding



Tidal range schemes can protect estuaries and coastal areas from the effects of sea level rise, according to researchers who say that tidal range schemes are vital to protect habitats, housing and businesses from a rising sea level estimated to be over one metre within 80 years. High tides can be limited to existing levels simply by closing sluices and turbines and existing low tide levels can be maintained by pumping. Development of estuarine barrages has been hampered by misconceptions about their operation and fears of disturbance of the ecologically sensitive intertidal areas.
Published Scientists uncover ocean's intricate web of microbial interactions across depths



An international team of scientists has uncovered the ocean's intricate web of microbial interactions across depths. Their research provides crucial insights into the functioning of ocean ecosystems.
Published Using idle trucks to power the grid with clean energy



Researchers are tapping into idled electric vehicles to act as mobile generators and help power overworked and aging electricity grids. After analyzing energy demand on Alberta's power grid during rush hour, the research proposes an innovative way to replenish electrical grids with power generated from fuel cells in trucks.
Published Scientists use heat to create transformations between skyrmions and antiskyrmions



In an experiment that could help the development of new spintronics devices with low energy consumption, researchers have used heat and magnetic fields to create transformations between spin textures -- magnetic vortices and antivortices known as skyrmions and antiskyrmions -- in a single crystal thin plate device. Importantly, they achieved this at room temperature.
Published A global study reveals pathways to save threatened sharks, despite rising mortality trends



Sharks have persisted as powerful ocean predators for more than 400 million years. They survived five mass extinctions, diversifying into an amazing variety of forms and lifestyles. But this ancient lineage is now among the world's most threatened species groups due to overexploitation in poorly regulated fisheries and the proliferation of wasteful finning practices.
Published Highly durable, nonnoble metal electrodes for hydrogen production from seawater



The water electrolysis method, a promising avenue for hydrogen production, relies on substantial freshwater consumption, thereby limiting the regions available with water resources required for water electrolysis . Researchers have developed highly durable electrodes without precious metals to enable direct hydrogen production from seawater.
Published Focus on biological processes does not capture the whole picture



The ocean plays a crucial role in the storage of carbon dioxide (CO2). The so-called marine biological carbon pump is an important research topic in this context. However a key component is often overlooked. Colleagues outline why it is insufficient to focus solely on biological processes when investigating the accumulation of CO2 in the ocean by the biological carbon pump.
Published New findings regarding the high efficiency of perovskite solar cells



Free charge carriers in perovskite solar cells likely have a special form of protection from recombination, researchers have discovered. This may be key to the high efficiency of this cell type, which has been increased to over 25 % within a decade.
Published In hot water: Coral resilience in the face of climate change



Researchers have been studying the effects of climate change on coral reefs. Monitoring two coral species off the coast of Hawaii, one team found that local adaptations in response to near-severe heat stress allowed certain populations to endure such events.
Published Acidity of Antarctic waters could double by century's end, threatening biodiversity



Without drastically reducing global emissions, the Antarctic Ocean could become too acidic for hundreds of species living there, many already endangered by rising temperatures and sea ice loss.
Published Green wheels, bright skies: Analysis unveils the connection between electric vehicles and photovoltaics



People who own electric vehicles (EVs) are more likely to go a step further and add solar panels to their home, according to an analysis of a behavioral study. Conversely, the impact of owning solar panels also has a bearing on whether a homeowner buys an electric vehicle but not as strongly.
Published With only the pawprints, researchers study elusive bobcat



With DNA recovered from animal tracks, scientists revealed information about the ancestry and microbial community of bobcats without having to sample the animal directly.
Published Green ammonia could decarbonize 60% of global shipping when offered at just 10 regional fuel ports



A study has found that green ammonia could be used to fulfill the fuel demands of over 60% of global shipping by targeting just the top 10 regional fuel ports. Researchers looked at the production costs of ammonia which are similar to very low sulphur fuels, and concluded that the fuel could be a viable option to help decarbonize international shipping by 2050.
Published Stranger than friction: A force initiating life



As the potter works the spinning wheel, the friction between their hands and the soft clay helps them shape it into all kinds of forms and creations. In a fascinating parallel, sea squirt oocytes (immature egg cells) harness friction within various compartments in their interior to undergo developmental changes after conception.
Published Protecting coral 'nurseries' as important as safeguarding established coral reefs



New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.
Published Fastest swimming insect could inspire uncrewed boat designs



Whirligig beetles, the world's fastest-swimming insect, achieve surprising speeds by employing a strategy shared by fast-swimming marine mammals and waterfowl, according to a new study that rewrites previous explanations of the physics involved.
Published Using berry phase monopole engineering for high-temperature spintronic devices



Spin-orbit torque (SOT), an important phenomenon for developing ultrafast and low-power spintronic devices, can be enhanced through Berry phase monopole engineering at high temperatures. In a new study, the temperature dependence of the intrinsic spin Hall effect of TaSi2 was investigated. The results suggest that Berry phase monopole engineering is an effective strategy for achieving high-temperature SOT spintronic devices.
Published The snail or the egg?



Animals reproduce in one of two distinct ways: egg-laying or live birth. By studying an evolutionarily recent transition from egg-laying to live-bearing in a marine snail, collaborative research has shed new light on the genetic changes that allow organisms to make the switch.
Published Male southern elephant seals are picky eaters



New research suggests these large marine mammals are extremely fussy and only eat their favorite foods.
