Published Fully recyclable printed electronics ditch toxic chemicals for water



Engineers have produced fully recyclable printed electronics that replace the use of chemicals with water in the fabrication process. By bypassing the need for hazardous chemicals, the demonstration points down a path industry could follow to reduce its environmental footprint and human health risks.
Published Sierra squirrels find their niche amid a changing climate



A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.
Published Discovery of ferroelectricity in an elementary substance



Researchers have discovered a new single-element ferroelectric material that alters the current understanding of conventional ferroelectric materials and has future applications in data storage devices.
Published New tool shows progress in fighting spread of invasive grass carp in Great Lakes



Researchers created a new way to estimate the abundance of invasive 'sleeper' species in freshwater ecosystems and help guide management strategies.
Published Insect decline also occurs in forests



The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.
Published Warming Arctic draws marine predators northwards



Marine predators have expanded their ranges into the Arctic waters over the last twenty years, driven by climate change and associated increases in productivity.
Published Strong ultralight material could aid energy storage, carbon capture



Materials scientists showed that fine-tuning interlayer interactions in a class of 2D polymers can determine the materials' loss or retention of desirable mechanical properties in multilayer or bulk form.
Published DELLA proteins could hold key to the next Green Revolution



A family of 'promiscuous' proteins found in all land plants is responsible for many different plant functions, despite remaining relatively unchanged for over 450 million years.
Published Can cities make room for woodpeckers?



Researchers are deploying the latest mapping techniques to identify the most important suburban habitat for North America's largest woodpecker. Wildlife habitat in congested places is becoming increasingly fragmented as forests give way to new construction. Eventually, this could spell trouble to an animal with specific habitat needs like the pileated woodpecker.
Published Ants took over the world by following flowering plants out of prehistoric forests


Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the evolution of the thousands of ant species alive today.
Published Scientists analyze sounds emitted by plants


Researchers have recorded and analyzed sounds distinctly emitted by plants. The click-like sounds, similar to the popping of popcorn, are emitted at a volume similar to human speech, but at high frequencies, beyond the hearing range of the human ear.
Published How plants cope with the cold light of day -- and why it matters for future crops


New research has discovered a cold 'coping' mechanism that is under the control of the plant biological clock and could offer solutions to breeding more resilience into crops less suited to cold climates.
Published How whale shark rhodopsin evolved to see, in the deep blue sea


A group of researchers discovered that the rhodopsin -- a protein in the eye that detects light -- of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions -- one of which is counterintuitively associated with congenital stationary night blindness in humans -- aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.
Published Is it COVID-19 or the flu? New sensor could tell you in 10 seconds


Have a cough, sore throat and congestion? Any number of respiratory viruses could be responsible. Today, scientists report using a single-atom-thick nanomaterial to build a device that can simultaneously detect the presence of the viruses that cause COVID-19 and the flu -- at much lower levels and much more quickly than conventional tests for either.
Published Conserving wildlife can help mitigate climate change


Solving the climate crisis and biodiversity crisis are not separate issues. Animals remove billions of tons of carbon dioxide each year. Restoring species will help limit global warming, new science reveals.
Published Even Sonoran Desert plants aren't immune to climate change


In North America's hottest, driest desert, climate change is causing the decline of plants once thought nearly immortal and replacing them with shorter shrubs that can take advantage of sporadic rainfall and warmer temperatures.
Published Turtles and crocodiles with unique characteristics are more likely to go extinct


New study demonstrates that the most endangered turtles and crocodile species are those that have evolved unique life strategies. Many of the most threatened species carry out important ecosystem functions that other species depend on. Habitat loss was identified as the key overall threat to turtles and crocodiles, followed by climate change and global trade. Unique species faced additional pressure from local consumption, diseases, and pollution.
Published Climate change threatens lemurs on Madagascar


Even supposedly adaptable mammal species face increased risk of extinction.
Published What should we call evolution driven by genetic engineering? Genetic welding, says researcher


With CRISPR-Cas9 technology, humans can now rapidly change the evolutionary course of animals or plants by inserting genes that can easily spread through entire populations. An evolutionary geneticist proposes that we call this evolutionary meddling 'genetic welding.' He argues that we must scientifically and ethically scrutinize the potential consequences of genetic welding before we put it into practice.
Published Nanophysics: The right twist


Stacked layers of ultrathin semiconductor materials feature phenomena that can be exploited for novel applications. Physicists have studied effects that emerge by giving two layers a slight twist.
