Published Mystery of moths' warning sound production explained in new study



The workings of the ultrasonic warning sounds produced by the wings of a species of moth have been revealed.
Published Computer-engineered DNA to study cell identities



A new computer program allows scientists to design synthetic DNA segments that indicate, in real time, the state of cells. It will be used to screen for anti-cancer or viral infections drugs, or to improve gene and cell-based immunotherapies.
Published Scientists 'break the mould' by creating new colors of 'blue cheese'



Experts have discovered how to create different colors of blue cheese. After discovering how the classic blue-green veining is created, a team of experts were able to create a variety of different fungal strains that could be used to make cheese with colors ranging from white to yellow-green to red-brown-pink and light and dark blues.
Published Mechanism discovered that protects tissue after faulty gene expression



A study has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead to new therapeutic approaches to treat diseases caused by faulty splicing.
Published Scammed! Animals 'led by the nose' to leave plants alone



Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.
Published Rare 3D fossils show that some early trees had forms unlike any you've ever seen



In the fossil record, trees typically are preserved with only their trunks. They don't usually include any leaves to show what their canopies and overall forms may have looked like. In a new study, researchers describe fossilized trees from New Brunswick, Canada with a surprising and unique three-dimensional crown shape.
Published How leafcutter ants cultivate a fungal garden to degrade plants and provide insights into future biofuels



Scientists developed a new method to map exactly how a fungus works with leafcutter ants in a complex microbial community to degrade plant material at the molecular level. The team's insights are important for biofuels development.
Published Zebrafish navigate to find their comfortable temperature



Zebrafish are smaller than your little finger, with a brain no more than half the size of a pinhead. Yet these animals possess an efficient navigation system that enables them to find their way back to spots in the water where the temperature suits them.
Published Clown anemonefish seem to be counting bars and laying down the law



We often think of fish as carefree swimmers in the ocean, reacting to the world around them without much forethought. However, new research suggests that our marine cousins may be more cognizant than we credit them for. Fish may be counting vertical bars on intruders to determine their threat level, and to inform the social hierarchy governing their sea anemone colonies.
Published The arrangement of bacteria in biofilms affects their sensitivity to antibiotics



Many bacteria form an antibiotic-resistant slime. Research detailing that slime's structure could help lead to new treatments.
Published LSH genes associated with defining the shapes of stems, flowers and leaves required for N-fixing root nodules



The developmental regulators that confer the identity of N-fixing root nodules belong to a transcription factor family (LSH) more commonly associated with defining the shapes of stems, flowers and leaves.
Published Discovery of a third RNA virus linage in extreme environments Jan 17, 2024



A research group has discovered a novel RNA viral genome from microbes inhabiting a high-temperature acidic hot spring. Their study shows that RNA viruses can live in high-temperature environments (70-80 degrees Celsius), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third kingdom may exist.
Published Using computers to design proteins allows researchers to make tunable hydrogels that can form both inside and outside of cells



New research demonstrates a new class of hydrogels that can form not just outside cells, but also inside of them. These hydrogels exhibited similar mechanical properties both inside and outside of cells, providing researchers with a new tool to group proteins together inside of cells.
Published Goats can tell if you are happy or angry by your voice alone



Goats can tell the difference between a happy-sounding human voice and an angry-sounding one, according to researchers. A new study reveals that goats may have developed a sensitivity to our vocal cues over their long association with humans.
Published DNA particles that mimic viruses hold promise as vaccines



Using a DNA-based delivery particle, researchers created a vaccine that can induce a strong antibody response against SARS-CoV-2.
Published Poultry scientists develop 3D anatomy technique to learn more about chicken vision



Poultry scientists are unraveling the complexities of bird brains and finding less expensive ways to do it. The scientists mapped the intricate neurological pathways that control vision in chickens with detailed 3D models of the connections between the eyes and four regions of the brain.
Published 'Genomic time machine' reveals secrets of our DNA



Researchers reveal a novel method to uncover bits of our genetic blueprint that come from ancient genetic parasites, offering fresh insights into human evolution and health.
Published Back from the dead: Tropical tree fern repurposes its dead leaves



Plant biologists report that a species of tree fern found only in Panama reanimates its own dead leaf fronds, converting them into root structures that feed the mother plant. The fern, Cyathea rojasiana, reconfigures these 'zombie leaves,' reversing the flow of water to draw nutrients back into the plant.
Published First-ever sighting of a live newborn great white



Great whites, the largest predatory sharks in the world with the most fatal attacks on humans, are tough to imagine as newborn babies. That is partially because no one has seen one in the wild, it seems, until now.
Published How macrophages regulate regenerative healing in spiny mice



A team of researchers is delving deeper into the science behind how spiny mice can regenerate lost tissue and using what they learn to trigger regeneration in other types of mice -- advances which one day may be translated into humans. Whereas adult laboratory mice heal injuries with scar tissue, spiny mice have the unique ability to regrow lost skin and regenerate musculoskeletal tissues in their body.
