Published Unlocking the genetic code of peppers: New study reveals insights into domestication and diversity
(via sciencedaily.com) Original source Peppers are a versatile, flavorful, and widely popular crop, used not only as a healthy food source but also for their medicinal properties. Scientists have now sequenced the genomes of key cultivated and wild pepper species, offering unprecedented insights into pepper evolution, domestication, and genetic diversity.
Published You say tomato, these scientists say evolutionary mystery
(via sciencedaily.com) Original source Biologists have found evidence for evolutionary 'syndromes'-- sets of traits that occur together -- that help to explain how tomatoes first evolved their distinctive blend of color, sweetness, acidity and aroma. The research not only shines a light on how fruits evolve in the wild, but will also be valuable to crop-improvement efforts aimed at breeding more nutritious and appealing varieties of fruits.
Published Super antifreeze in cells: The ability to survive in ice and snow developed in animals far earlier than we thought
(via sciencedaily.com) Original source More than 400 million years ago, an insect-like animal called the springtail developed a small protein that prevents its cells from freezing.
Published Lions on the brink -- New analysis reveals the differing threats to African lion populations
(via sciencedaily.com) Original source New results reveal that many of Africa's remaining lions live within small, fragmented populations at risk of disappearing. The researchers developed a new framework which integrates ecological and socio-political risk factors to better understand the fragility of these populations.
Published 'A crab is never just a crab'
(via sciencedaily.com) Original source A herring in the North Sea, a crab in the Wadden Sea or an anemone fish on a coral reef, ... biologists like to think in terms of individual species that all have their own place within food webs in ecosystems across the world. 'But that is surely too simplistic thinking,' researchers warn.
Published Researchers make a significant step towards reliably processing quantum information
(via sciencedaily.com) Using laser light, researchers have developed the most robust method currently known to control individual qubits made of the chemical element barium. The ability to reliably control a qubit is an important achievement for realizing future functional quantum computers.
Published Jackdaws switch friends to gain food -- but stick with family
(via sciencedaily.com) Original source Jackdaws ditch old friends and make new ones if it helps them get rewards -- but stick with family through thick and thin, new research shows.
Published Scientists find evidence of sea star species hybridization
(via sciencedaily.com) A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.
Published Contours that kill: Geometry influences prey capture in carnivorous pitcher plants
(via sciencedaily.com) Original source Researchers have shown that the shape, size, and geometry of carnivorous pitcher plants determines the type of prey they trap.
Published Valleytronics: Innovative way to store and process information up to room temperature
(via sciencedaily.com) Researchers have found a way to maintain valley polarization at room temperature using novel materials and techniques.
Published Echoes of extinctions: Novel method unearths disruptions in mammal trait-environment relationships
(via sciencedaily.com) Original source New research explores the historical shifts in mammal traits and biodiversity loss in eastern Africa. The study reveals how environmental changes disrupted mammal communities and highlights the urgent need for targeted conservation efforts to protect vulnerable species.
Published Dog diversity unveiled by international DNA database
(via sciencedaily.com) Original source An international consortium of scientists is using an unprecedentedly large database of canine DNA to take an unbiased look at how our furry friends evolved into the various breeds we know and love.
Published Machine learning contributes to better quantum error correction
(via sciencedaily.com) Researchers have used machine learning to perform error correction for quantum computers -- a crucial step for making these devices practical -- using an autonomous correction system that despite being approximate, can efficiently determine how best to make the necessary corrections.
Published Disease affects blackbirds more than previously thought
(via sciencedaily.com) Original source When humans are ill, we tend to be less active. This also applies to wild animals, but so far, it has not been known how long the reduced activity lasts or which activities are affected the most. New research shows that birds' activity decreases for up to three weeks when they become ill -- something that could mean the difference between life and death.
Published Human shoulders and elbows first evolved as brakes for climbing apes
(via sciencedaily.com) Original source Researchers report that the flexible shoulders and elbows that allow us to throw a football or reach a high shelf may have evolved as a natural braking system that let our primate ancestors get out of trees without dying. The researchers used sports-analysis software to compare the climbing movements of chimpanzees and small monkeys called mangabeys. While the animals climb up trees similarly, the researchers found that the shallow, rounded shoulder joints and shortened elbow bones that chimps have -- similar to humans -- allow them to fully extend their arms above their heads when climbing down, holding onto branches like a person going down a ladder to support their greater weight. When early humans left forests for the grassy savanna, these versatile appendages would have been essential for gathering food and using tools for hunting and defense. The findings are among the first to identify the significance of 'downclimbing' in the evolution of apes and early humans.
Published Invasive species are animals, too: Considering a humane approach
(via sciencedaily.com) Invasive alien species are animals that may pose a threat to biodiversity, but it's time to deal with that threat in a more ethical way.
Published Large herbivores keep invasive plants at bay
(via sciencedaily.com) Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.
Published Atomically-precise quantum antidots via vacancy self-assembly
(via sciencedaily.com) Scientists demonstrated a conceptual breakthrough by fabricating atomically precise quantum antidots using self-assembled single vacancies in a two-dimensional transition metal dichalcogenide.
Published Deriving the fundamental limit of heat current in quantum mechanical many-particle systems
(via sciencedaily.com) Researchers have mathematically derived the fundamental limit of heat current flowing into a quantum system comprising numerous quantum mechanical particles in relation to the particle count. Further, they established a clearer understanding of how the heat current rises with increasing particle count, shedding light on the performance constraints of potential future quantum thermal devices.
Published Farms that create habitat key to food security and biodiversity
(via sciencedaily.com) Diversified farming is an important complement to forest protections for reversing tropical biodiversity declines.
