Published Canopy gaps help eastern hemlock outlast invasive insect
(via sciencedaily.com) Original source Creating physical gaps in the forest canopy give eastern hemlocks more access to resources and help those trees withstand infestation by an invasive insect.
Published The pace of climate-driven extinction is accelerating
(via sciencedaily.com) Original source Studying a lizard species in Arizona mountains, researchers found 70 years' worth of climate-related extinction occurred in only seven years.
Published Incubator or barrier? Exploring the links between agriculture, biodiversity and the spread of pathogens
(via sciencedaily.com) Many pathogens, including the virus that causes COVID-19, are thought to have originated in wild animals before spilling into human populations.
Published New clues to the nature of elusive dark matter
(via sciencedaily.com) A team of international researchers has uncovered further clues in the quest for insights into the nature of dark matter. The key to understanding this mystery could lie with the dark photon, a theoretical massive particle that may serve as a portal between the dark sector of particles and regular matter.
Published Almost half of koala habitats will be under high bushfire threat by 2070
(via sciencedaily.com) The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.
Published Golden future for thermoelectrics
(via sciencedaily.com) Researchers discover excellent thermoelectric properties of nickel-gold alloys. These can be used to efficiently convert heat into electrical energy.
Published Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration
(via sciencedaily.com) • Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.
Published Clever lapwings use cover to hide in plain sight
(via sciencedaily.com) Original source Ground-nesting birds called lapwings use the shape of their nests and surroundings to hide from predators, new research shows.
Published Carbon atoms coming together in space
(via sciencedaily.com) Original source Lab-based studies reveal how carbon atoms diffuse on the surface of interstellar ice grains to form complex organic compounds, crucial to reveal the chemical complexity in the universe.
Published Rivers are rapidly warming, losing oxygen; aquatic life at risk
(via sciencedaily.com) Original source Rivers are warming and losing oxygen faster than oceans, according to a new article. The study shows that of nearly 800 rivers, warming occurred in 87% and oxygen loss occurred in 70%.
Published Making hydrogen from waste plastic could pay for itself
(via sciencedaily.com) Researchers have found a way to harvest hydrogen from plastic waste using a low-emissions method that generates graphene as a by-product, which could help offset production costs.
Published Scientists invent a bright way to upcycle plastics into liquids that can store hydrogen energy
(via sciencedaily.com) Scientists have created a process that can upcycle most plastics into chemicals useful for energy storage, using light-emitting diodes (LEDs) and a commercially available catalyst, all at room temperature. The new process is very energy-efficient and can be easily powered by renewable energy in the future, unlike other heat-driven recycling processes like pyrolysis. Currently, only nine per cent of plastics globally are recycled and the rest are typically discarded in landfills or incinerated.
Published Protected nature reserves alone are insufficient for reversing biodiversity loss
(via sciencedaily.com) Original source Protected nature areas are considered fundamental for maintaining biodiversity and countering its loss. But how effectively do established protected areas work and prevent negative trends? Research shows mixed effects of protected areas on various species.
Published New research reveals why and when the Sahara Desert was green
(via sciencedaily.com) Original source A pioneering study has shed new light on North African humid periods that have occurred over the past 800,000 years and explains why the Sahara Desert was periodically green.
Published Pixel-by-pixel analysis yields insights into lithium-ion batteries
(via sciencedaily.com) By mining X-ray images, researchers have made significant new discoveries about the reactivity of lithium iron phosphate, a material used in batteries for electric cars and in other rechargeable batteries.
Published Chemist uses nature as inspiration for a sustainable, affordable adhesive system
(via sciencedaily.com) A chemist drew inspiration from the natural world, from his experiences scuba diving to studying shellfish in his lab. He has developed a sustainable adhesive system -- an alternative to toxic, permanent, traditional adhesives.
Published Freshwater connectivity can transport environmental DNA through the landscape
(via sciencedaily.com) A new article uses environmental DNA (eDNA) metabarcoding to analyze fish and zooplankton communities. The study found that the movement of water between freshwater bodies, or freshwater connectivity, can transport eDNA. This highlights the potential of eDNA to provide a comprehensive view of freshwater biodiversity.
Published Nature's great survivors: Flowering plants survived the mass extinction that killed the dinosaurs
(via sciencedaily.com) Original source A new study by researchers from the University of Bath (UK) and Universidad Nacional Autónoma de México (Mexico) shows that flowering plants escaped relatively unscathed from the mass extinction that killed the dinosaurs 66 million years ago. Whilst they suffered some species loss, the devastating event helped flowering plants become the dominant type of plant today.
Published Researchers detail how disorder alters quantum spin liquids, forming a new phase of matter
(via sciencedaily.com) Physicists begin to shed light on one of the most important questions regarding quantum spin liquids, and they do so by introducing a new phase of matter.
Published Plant-based food alternatives could support a shift to global sustainability
(via sciencedaily.com) Replacing 50% of meat and milk products with plant-based alternatives by 2050 can reduce agriculture and land use related greenhouse gas (GHG) emissions by 31% and halt the degradation of forest and natural land, according to new research.
