Published Hundreds of Andean bird species at risk due to deforestation: New research shows how to protect them



Birds native to the tropical Andes are threatened by increasing agricultural development in the region. A new study combines a meta-analysis of papers on birds across the Andes with five years of fieldwork in Peru, revealing that open farmlands result in up to a 60% decline in the number of species in an area. The study documents how specific species are affected and provides tailored guidance for conservationists trying to protect them.
Published Coffee offers performance boost for concrete



Engineers in Australia have found a way of making stronger concrete with roasted used-coffee grounds, to give the drink-additive a 'double shot' at life and reduce waste going to landfills. The team developed a technique to make concrete 30% stronger by turning waste coffee grounds into biochar, using a low-energy process without oxygen at 350 degrees Celsius.
Published Did sabertooth tigers purr or roar?



When a sabertooth tiger called out, what noise did it make -- a mighty roar or a throaty purr? A new study examined the data behind the arguments for each vocalization and found that the answer was more nuanced than they thought -- and that it could depend on the shape of a few small bones.
Published The modern sea spider had started to diversify by the Jurassic, study finds



An extremely rare collection of 160-million-year-old sea spider fossils from Southern France are closely related to living species, unlike older fossils of their kind.
Published Transforming flies into degradable plastics



Imagine using insects as a source of chemicals to make plastics that can biodegrade later -- with the help of that very same type of bug. That concept is closer to reality than you might expect. Researchers will describe their progress to date, including the isolation and purification of the insect-derived chemicals and their conversion into their bioplastics.
Published 3D-printed vegan seafood could someday be what's for dinner



More mock seafood options are needed because of unsustainable fishing and aquaculture practices, which can harm the environment. Now, researchers have a new approach for creating desirable vegan seafood mimics that taste good, while maintaining the healthful profile of real fish. They 3D-printed an ink made from microalgae protein and mung bean protein, and their proof-of-concept calamari rings were air-fried into a snack.
Published Tattoo technique transfers gold nanopatterns onto live cells


For now, cyborgs exist only in fiction, but the concept is becoming more plausible as science progresses. And now, researchers are reporting that they have developed a proof-of-concept technique to 'tattoo' living cells and tissues with flexible arrays of gold nanodots and nanowires. With further refinement, this method could eventually be used to integrate smart devices with living tissue for biomedical applications, such as bionics and biosensing.
Published Fossil feces infested with parasites from over 200 million years ago



Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a new study.
Published The 'unknome': A database of human genes we know almost nothing about



Researchers hope that a new, publicly available database they have created will shrink, not grow, over time. That's because it is a compendium of the thousands of understudied proteins encoded by genes in the human genome, whose existence is known but whose functions are mostly not.
Published City-dwelling wildlife demonstrate 'urban trait syndrome'


City life favors species that are adaptable and not too fussy about what they eat, among other characteristics. A worldwide consortium of scientists calls the resulting collection of traits an 'Urban Trait Syndrome.'
Published Managing domestic and wildcats is likely to remain fraught, new research warns



Current efforts to protect and restore native biodiversity is being threatened by difficulties in identifying wild and domestic cats, and categorization is likely to remain fraught for the foreseeable future, experts have warned.
Published Whale-like filter-feeding discovered in prehistoric marine reptile



A remarkable new fossil from China reveals for the first time that a group of reptiles were already using whale-like filter feeding 250 million years ago.
Published Latest in body art? 'Tattoos' for individual cells



Engineers have developed nanoscale tattoos -- dots and wires that adhere to live cells -- in a breakthrough that puts researchers one step closer to tracking the health of individual cells.
Published Butterflies can remember where things are over sizeable spaces



Heliconius butterflies are capable of spatial learning, scientists have discovered. The results provide the first experimental evidence of spatial learning in any butterfly or moth species.
Published Study reveals successful strategies for removing invasive caimans from Florida Everglades


A new study reveals how a succession of strategies can take control of an invasive species population.
Published Discovery in nanomachines within living organisms -- cytochromes P450 (CYP450s) unleashed as living soft robots



A new study suggests that Cytochromes P450 (CYP450s) enzymes can sense and respond to stimuli, acting like soft robots in living systems.
Published Tropical trees use social distancing to maintain biodiversity



Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.
Published Scientists dig into wildfire predictions, long-term impacts



Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.
Published Sea level rise shifts habitat for endangered Florida Keys species



A newly published study describes the response to sea level rise by the silver rice rat, an endangered species only found in the Florida Keys.
Published Nuisance vegetation removal in Senegalese waterways reduces the overall prevalence of parasitic infections and increases local food production



It's an elegant solution: Remove the habitat of a parasite-carrying aquatic snail and reduce the level of infection in the local community; all while generating more feed and compost for local farmers.
