Published Using AI to find the polymers of the future



Finding the next groundbreaking polymer is always a challenge, but now researchers are using artificial intelligence (AI) to shape and transform the future of the field.
Published How 'winner and loser effects' impact social rank in animals -- and humans



A new article provides a narrative review of the relevant similarities and distinctions between nonhumans and humans to assess the causes and consequences of winner and loser effects in humans.
Published Searching old stem cells that stay young forever



The sea anemone Nematostella vectensis is potentially immortal. Using molecular genetic methods, developmental biologists have now identified possible candidates for multipotent stem cells in the sea anemone for the first time. These stem cells are regulated by evolutionary highly conserved genes.
Published Spider exploits firefly's flashing signals to lure more prey



Fireflies rely on flashing signals to communicate to other fireflies using light-emitting lanterns on their abdomens. In fireflies of the species Abscondita terminalis, males make multi-pulse flashes with two lanterns to attract females, while females make single-pulse flashes with their one lantern to attract males. Now researchers have evidence that an orb-weaving spider (Araneus ventricosus) manipulates the flashing signals of male fireflies ensnared in its web such that they mimic the typical flashes of a female firefly, thereby luring other males to serve as their next meal.
Published Revolutionizing thermoelectric technology: Hourglass-shaped materials achieve a 360% efficiency boost



A groundbreaking technology has been unveiled that improves the efficiency of thermoelectric materials, which are key in converting waste heat into electricity, by altering their geometry to resemble an hourglass. Unlike previous research that solely depended on the material properties of thermoelectric substances, this new approach is expected to have widespread applications in thermoelectric power generation.
Published Rethinking the dodo



Researchers are setting out to challenge our misconceptions about the Dodo, one of the most well-known but poorly understood species of bird. Researchers have undertaken the most comprehensive review of the taxonomy of the Dodo and its closest relative, the Rodriguez Island Solitaire.
Published New research shows unprecedented atmospheric changes during May's geomagnetic superstorm



On May 11, a gorgeous aurora surprised stargazers across the southern United States. That same weekend, a tractor guided by GPS missed its mark. What do the visibility of the northern lights have in common with compromised farming equipment in the Midwest? A uniquely powerful geomagnetic storm, according to new research.
Published Engineers design tiny batteries for powering cell-sized robots



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 Blind cavefish have extraordinary taste buds



A biologist studies blind cavefish, a species of fish that dwell in cave ponds in Mexico. He looked at the timeline for when the cavefish develop additional taste buds on the head and chin, finding the taste bud expansion starts at five months and continues into adulthood.
Published Research provides a roadmap for improving electrochemical performance



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 Surprise finding in study of environmental bacteria could advance search for better antibiotics



Researchers studying bacteria from freshwater lakes and soil say they have determined a protein's essential role in maintaining the germ's shape. Because the integrity of a bacterial cell's 'envelope' or enclosure is key to its survival, the finding could advance the search for new and better antibiotics.
Published Why do plants wiggle? New study provides answers



Decades after his voyage on the HMS Beagle, Charles Darwin became fascinated by why plants move as they grow -- spinning and twisting into corkscrews. Now, more than 150 years later, a new study may have solved the riddle.
Published Smart fabric converts body heat into electricity



Researchers have developed a smart fabric that can convert body heat and solar energy into electricity, potentially enabling continuous operation with no need for an external power source. Different sensors monitoring temperature, stress, and more can be integrated into the material.
Published A method that paves the way for improved fuel cell vehicles



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 Decoding the world's largest animal genome



Scientists have sequenced the largest genome of all animals, the lungfish genome. Their data help to explain how the fish-ancestors of today's land vertebrates were able to conquer land.
Published Giant fossil seeds from Borneo record ancient plant migration



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



Scientists have trialled a new way to protect freshwater crocodiles from deadly invasive cane toads spreading across northern Australia.
Published Halogen bonding for selective electrochemical separation, path to sustainable chemical processing demonstrated



A team has reported the first demonstration of selective electrochemical separation driven by halogen bonding. This was achieved by engineering a polymer that modulates the charge density on a halogen atom when electricity is applied. The polymer then attracts only certain targets -- such as halides, oxyanions, and even organic molecules -- from organic solutions, a feature that has important implications for pharmaceuticals and chemical synthesis processes.
Published Rewriting the evolutionary history of critical components of the nervous system



A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.
Published Reduce, reuse, 're-fly-cle'



Black soldier flies are now commercially used to consume organic waste -- but genetic modifications proposed by bioscientists could see the insects digesting a wider variety of refuse, while also creating raw ingredients for industry.
