Published Genomic study sheds light on how carnivorous Asian pitcher plants acquired signature insect trap
(via sciencedaily.com) Original source Scientists sequenced the genome of the East Asian pitcher plant, Nepenthes gracilis, a species of carnivorous plant related to Venus flytraps, as well as sundews, beets and spinach.
Published Sea fireflies synchronize their sparkle to seek soulmates
(via sciencedaily.com) Original source In sea fireflies' underwater ballet, the males sway together in perfect, illuminated synchronization, basking in the glow of their secreted iridescent mucus.
Published Researchers show an old law still holds for quirky quantum materials
(via sciencedaily.com) Original source Long before researchers discovered the electron and its role in generating electrical current, they knew about electricity and were exploring its potential. One thing they learned early on was that metals were great conductors of both electricity and heat. And in 1853, two scientists showed that those two admirable properties of metals were somehow related: At any given temperature, the ratio of electronic conductivity to thermal conductivity was roughly the same in any metal they tested. This so-called Wiedemann-Franz law has held ever since -- except in quantum materials. Now, a theoretical argument put forth by physicists suggests that the law should, in fact, approximately hold for one type of quantum material, the cuprate superconductors.
Published Broadband buzz: Periodical cicadas' chorus measured with fiber optic cables
(via sciencedaily.com) Original source Through an emerging technology called distributed fiber optic sensing, cables bringing high-speed internet to American households can be used to detect temperature changes, vibrations, and even sound. And periodical cicadas -- the insects that emerge by the billions every 13 or 17 years and make a racket with their mating calls -- are loud enough to be detected. A new study shows how fiber optic sensing could open new pathways for charting populations of these famously ephemeral bugs.
Published The waxy surface protecting plants might hold the key to developing stronger crops
(via sciencedaily.com) Original source Researchers have discovered that the waxy protective barrier around plants might play a role in sending chemical signals to other plants and insects.
Published Unknown animals were leaving bird-like footprints in Late Triassic Southern Africa
(via sciencedaily.com) Original source Ancient animals were walking around on bird-like feet over 210 million years ago, according to a new study.
Published Quantum tool opens door to uncharted phenomena
(via sciencedaily.com) Original source Scientists have developed a new tool for the measurement of entanglement in many-body systems and demonstrated it in experiments. The method enables the study of previously inaccessible physical phenomena and could contribute to a better understanding of quantum materials.
Published How shifting climates may have shaped early elephants' trunks
(via sciencedaily.com) Original source Researchers have provided new insights into how ancestral elephants developed their dextrous trunks. A study of the evolution of longirostrine gomphotheres, an ancestor of the modern day elephant, suggests moving into open-land grazing helped develop their coiling and grasping trunks.
Published Nextgen computing: Hard-to-move quasiparticles glide up pyramid edges
(via sciencedaily.com) Original source A new kind of 'wire' for moving excitons could help enable a new class of devices, perhaps including room temperature quantum computers.
Published Hybrid transistors set stage for integration of biology and microelectronics
(via sciencedaily.com) Original source Researchers create transistors combining silicon with biological silk, using common microprocessor manufacturing methods. The silk protein can be easily modified with other chemical and biological molecules to change its properties, leading to circuits that respond to biology and the environment.
Published This sea worm's posterior body part swims away, and now scientists know how
(via sciencedaily.com) Original source A research team shows how the expression of developmental genes in the Japanese green syllid worms, Megasyllis nipponica, helps form their swimming reproductive unit called stolon.
Published Sophisticated swarming: Bacteria support each other across generations
(via sciencedaily.com) Original source When bacteria build communities, they cooperate and share nutrients across generations. Researchers have been able to demonstrate this for the first time using a newly developed method. This innovative technique enables the tracking of gene expression during the development of bacterial communities over space and time.
Published Trilobites rise from the ashes to reveal ancient map
(via sciencedaily.com) Original source Ten newly discovered species of trilobites, hidden for 490 million years in a little-studied part of Thailand, could be the missing pieces in an intricate puzzle of ancient world geography.
Published Unearthing how a carnivorous fungus traps and digests worms
(via sciencedaily.com) Original source A new analysis sheds light on the molecular processes involved when a carnivorous species of fungus known as Arthrobotrys oligospora senses, traps and consumes a worm.
Published Innovative aquaculture system turns waste wood into nutritious seafood
(via sciencedaily.com) Original source Innovative aquaculture system turns waste wood into nutritious seafood. Researchers hoping to rebrand a marine pest as a nutritious food have developed the world's first system of farming shipworms, which they have renamed 'Naked Clams'.
Published Like the phoenix, Australia's giant birds of prey rise again from limestone caves
(via sciencedaily.com) Original source Australia's only vulture, and a fearsome extinct eagle, are among the earliest recorded birds of prey from the Pleistocene period more than 50,000 years ago -- and now researchers are bringing them to 'life' again. Along with new scientific information, a bold new pictorial reconstruction of a newly named eagle and the only known Australian vulture will be unveiled at the World Heritage-listed Naracoorte Caves in South Australia's Limestone Coast this month.
Published Much more than waste: Tiny vesicles exchange genetic information between cells in the sea
(via sciencedaily.com) Original source Researchers take a look at data that has so far been mostly discarded as contamination, revealing the previously underestimated role of extracellular vesicles (EVs). These are important for the exchange of genetic information between cells and thus for the microbial community in the sea.
Published Birds set foot near South Pole in Early Cretaceous, Australian tracks show
(via sciencedaily.com) Original source The discovery of 27 avian footprints on the southern Australia coast -- dating back to the Early Cretaceous when Australia was still connected to Antarctica -- opens another window onto early avian evolution and possible migratory behavior.
Published Forget social distancing: House finches become more social when sick
(via sciencedaily.com) Original source Social distancing when sick has become second nature to many of us in the past few years, but some sick animals appear to take a different approach. A new study of house finches uncovered a surprising result. Unlike other social animals who passively or actively isolate themselves when sick, this gregarious backyard bird species gravitates toward healthy flock mates when they are sick, even more so than healthy birds do.
Published Hemp cannabinoids may have evolved to deter insect pests
(via sciencedaily.com) Original source Cannabinoids, naturally occurring compounds found in hemp plants, may have evolved to deter pests from chewing on them, according to new research that showed higher cannabinoid concentrations in hemp leaves led to proportionately less damage from insect larvae.
