Published Biodiversity engine for fishes: Shifting water depth


Fish, the most biodiverse vertebrates in the animal kingdom, present evolutionary biologists a conundrum: The greatest species richness is found in the world's tropical waters, yet the fish groups that generate new species most rapidly inhabit colder climates at higher latitudes. A new study helps to explain this paradox. The researchers discovered that the ability of fish in temperate and polar ecosystems to transition back and forth from shallow to deep water triggers species diversification. Their findings suggest that as climate change warms the oceans at higher latitudes, it will impede the evolution of fish species.
Published Urban gardens are good for ecosystems and humans


Traditionally, it has been assumed that cultivating food leads to a loss of biodiversity and negative impacts on an ecosystem. A new study defies this assumption, showing that community gardens and urban farms positively affect biodiversity, local ecosystems and the well-being of humans that work in them.
Published How does biodiversity change globally? Detecting accurate trends may be currently unfeasible


Existing data are too biased to provide a reliable picture of the global average of local species richness trends.
Published Novel microscope developed to design better high-performance batteries


A research team has developed an operando reflection interference microscope (RIM) that provides a better understanding of how batteries work, which has significant implications for the next generation of batteries.
Published Beyond lithium: A promising cathode material for magnesium rechargeable batteries


Magnesium is a promising candidate as an energy carrier for next-generation batteries. However, the cycling performance and capacity of magnesium batteries need to improve if they are to replace lithium-ion batteries. To this end, a research team focused on a novel cathode material with a spinel structure. Following extensive characterization and electrochemical performance experiments, they have found a specific composition that could open doors to high-performance magnesium rechargeable batteries.
Published Endangered Bahamas bird may be lost from island following hurricane


The endangered Bahama Warbler may be surviving on just one island following Hurricane Dorian's devastation in 2019, according to researchers. A new study shows the bird's distribution and ecology on Grand Bahama before the hurricane struck. But the team says that the warbler may now only survive on neighboring Abaco island, after hurricane Dorian destroyed the bird's forest habitat on Grand Bahama. The research comes from the same team that found what is thought to have been the last living Bahama Nuthatch, previously thought to have been extinct.
Published Controllable 'defects' improve performance of lithium-ion batteries


Some defects can be good. A new study shows that laser-induced defects in lithium-ion battery materials improve the performance of the battery.
Published Marine reserves unlikely to restore marine ecosystems


Protected marine areas are one of the essential tools for the conservation of natural resources affected by human impact -- mainly fishing --, but, are they enough to recover the functioning of these systems? A study now highlights the limitations of marine reserves in restoring food webs to their pristine state prior to the impact of intensive fishing.
Published Global wetlands losses overestimated despite high losses in many regions


New analysis shows the U.S. has accounted for more wetland conversion and degradation than any other country. Its findings help better explain the causes and impacts of such losses and inform protection and restoration of wetlands.
Published A fossil fruit from California shows ancestors of coffee and potatoes survived cataclysm that killed the dinosaurs



The discovery of an 80-million-year-old fossil plant pushes back the known origins of lamiids to the Cretaceous, extending the record of nearly 40,000 species of flowering plants including modern-day staple crops like coffee, tomatoes, potatoes and mint.
Published New sodium, aluminum battery aims to integrate renewables for grid resiliency


A new sodium battery technology shows promise for helping integrate renewable energy into the electric grid. The battery uses Earth-abundant raw materials such as aluminum and sodium.
Published Long-term restoration of a biodiversity hotspot hinges on getting seeds to the right place at the right time


New research shows that degraded savanna ecosystems can reap lasting benefits from a single seeding of native understory plants. Once a diverse understory of savanna plants became established, its long-term persistence was relatively unaffected by environmental factors -- with one exception. Higher temperatures during the height of the growing season were associated with poorer long-term survival among some species, indicating one threat posed by a warming climate.
Published Pacific Northwest heat dome tree damage more about temperature than drought, scientists say



Widespread tree scorch in the Pacific Northwest that became visible shortly after multiple days of record-setting, triple-digit temperatures in June 2021 was more attributable to heat than to drought conditions, researchers say.
Published Small isolated wetlands are pollution-catching powerhouses



Small isolated wetlands that are full for only part of the year are often the first to be removed for development or agriculture, but a new study shows that they can be twice as effective in protecting downstream lake or river ecosystems than if they were connected to them.
Published Protected areas fail to safeguard more than 75% of global insect species


Insects play crucial roles in almost every ecosystem -- they pollinate more than 80% of plants and are a major source of food for thousands of vertebrate species -- but insect populations are collapsing around the globe, and they continue to be overlooked by conservation efforts. Protected areas can safeguard threatened species but only if these threatened species actually live within the areas we protect. A new study found that 76% of insect species are not adequately covered by protected areas.
Published Mixing between species reduces vulnerability to climate change


New research provides rare evidence that natural hybridization can reduce the risk of extinction of species threatened by climate change. Researchers have identified genes that enable Rainbowfish to adapt to climate variations across the Australia using environmental models to work out how much evolution will likely be required for populations to keep pace with future climate change.
Published UK's Overseas Territories at ongoing risk from wide range of invasive species


A new study has for the first time predicted which invasive species could pose a future threat to the UK's ecologically unique Overseas Territories.
Published A fairy-like robot flies by the power of wind and light


The loss of pollinators, such as bees, is a huge challenge for global biodiversity and affects humanity by causing problems in food production. Researchers have now developed the first passively flying robot equipped with artificial muscle. Could this artificial fairy be utilized in pollination?
Published Researchers decipher atomic-scale imperfections in lithium-ion batteries


Scientists have conducted a detailed examination of high-nickel-content layered cathodes, considered to be components of promise in next-generation lithium-ion batteries. Advanced electron microscopy and deep machine learning enabled the team to observe atomic-scale changes at the interface of materials that make up the batteries.
Published Recyclable mobile phone batteries a step closer with rust-busting invention


Mobile phone batteries with a lifetime up to three times longer than today's technology could be a reality thanks to a recent innovation.
