“#Self-powered ‘paper chips’ could help sound an early alarm for forest fires” A sensor (white strip) on a houseplant activates an alarm when fire is near. Credit: Adapted from ACS Applied Materials & Interfaces 2020 Recent devastating fires in the Amazon rain forest and the Australian bush highlight the need to detect forest fires at…
“#Weed’s wily ways explained in Illinois research” Credit: University of Illinois at Urbana-Champaign Like antibiotic-resistant bacteria, some herbicide-resistant weeds can’t be killed by available chemicals. The problem affects more than just the errant weed in our driveways; herbicide-resistant weeds threaten our food supply, stealing resources and outcompeting the crops that make up our breakfast cereal…
“#Earth’s species have more in common than previously believed” Credit: CC0 Public Domain The Earth hosts an abundance of life forms—from well-known animals and plants to small, more hardy life forms such as archaea, viruses and bacteria. These life forms are fundamentally different all the way down to the cell level—or so scientists thought. Now,…
“#Molecular containers for the sequestration of neurotransmitter drugs in water” “Pillar[n]MaxQ: A New High Affinity Host Family for Sequestration in Water.” Credit: Angewandte Chemie International Edition Molecular containers that remove drugs, toxins, or malodorous substances from the environment are called sequestering agents. Scientists have developed a class of molecular containers that specifically sequester neurotransmitter antagonists….
“#New study suggests that hard eggshells evolved at least three times in dinosaur family tree” The clutch of fossilized Protoceratops eggs and embryos examined in this study was discovered in the Gobi Desert of Mongolia at Ukhaa Tolgod. Credit: M. Ellison/©AMNH New research suggests that the first dinosaurs laid soft-shelled eggs—a finding that contradicts established…
“#Knock-knock? Who’s there? How coral let symbiotic algae in” The soft coral Xenia growing in the Carnegie coral research facility. Researchers used it to reveal the type of cell that enables a soft coral to recognize and take up the photosynthetic algae with which it maintains a symbiotic relationship, as well as the genes responsible…
“#Tomato’s hidden mutations revealed in study of 100 varieties” After centuries of breeding, tomatoes now take all sorts of shapes and sizes, from cherry-like to hefty heirloom fruit. Scientists are teasing out at the level of genes how and why these physical changes show up. Credit: Lippman Lab/CSHL/HHMI DNA and all. After centuries of breeding,…

“#First egg from Antarctica is big and might belong to an extinct sea lizard” An artist’s interpretation of a baby mosasaur emerging from an egg just moments after it was laid. The scene is set in the shallow waters of Late Cretaceous Antarctica. In the background, mountains are covered in vegetation due to a warm…
“#First-degree incest: Ancient genomes uncover Irish passage tomb for dynastic elite” Newgrange as seen on a misty morning. Credit: Ken Williams, shadowsandstone.com Archeologists and geneticists, led by those from Trinity College Dublin, have shed new light on the earliest periods of Ireland’s human history. Among their incredible findings is the discovery that the genome of…
