Published Surprising behavior in one of the least studied mammals in the world
(via sciencedaily.com) Original source Beaked whales are among the least studied mammals in the world. Now, a new study reveals surprising information about the Baird's beaked whale species.
Published Researchers discover new cell that remembers allergies
(via sciencedaily.com) Original source Researchers have made a groundbreaking discovery: a new cell that remembers allergies.
Published New research uncovers biological drivers of heart disease risk
(via sciencedaily.com) Original source Over the past 15 years, researchers have identified hundreds of regions in the human genome associated with heart attack risk. However, researchers lack efficient ways to explore how these genetic variants are molecularly connected to cardiovascular disease, limiting efforts to develop therapeutics. To streamline analysis of hundreds of genetic variants associated with coronary artery disease (CAD), a team of researchers combined multiple sequencing and experimental techniques to map the relationship between known CAD variants and the biological pathways they impact.
Published Spent hemp biomass: A feed use that supports milk production in dairy cows
(via sciencedaily.com) Original source A new study explores whether the plentiful, fibrous byproduct of CBD production holds potential promise as a nutritious, efficiency-boosting feed ingredient for the dairy sector
Published New approach to tackling bacterial infections identified
(via sciencedaily.com) Original source Researchers have identified a new approach to controlling bacterial infections. The team found a way to turn on a vital bacterial defense mechanism to fight and manage bacterial infections. The defense system, called cyclic oligonucleotide-based antiphage signaling system (CBASS), is a natural mechanism used by certain bacteria to protect themselves from viral attacks. Bacteria self-destruct as a means to prevent the spread of virus to other bacterial cells in the population.
Published Researchers discover key to molecular mystery of how plants respond to changing conditions
(via sciencedaily.com) Original source A team of researchers recently published a pioneering study that answers a central question in biology: how do organisms rally a wide range of cellular processes when they encounter a change -- either internally or in the external environment -- to thrive in good times or survive the bad times? The research, focused on plants, identifies the interactions between four compounds: pectin, receptor proteins FERONIA and LLG1 and the signal RALF peptide.
Published Ancient Australian air-breathing fish from 380 million years ago
(via sciencedaily.com) Original source The rivers of Australia, which once flowed across its now dry interior, used to host a range of bizarre animals -- including a sleek predatory lobe-finned fish with large fangs and bony scales. The newly described fossil fish discovered in remote fossil fields west of Alice Springs has been named Harajicadectes zhumini by palaeontologists.
Published Scientists develop new biocontainment method for industrial organisms
(via sciencedaily.com) Original source Researchers have developed a new biocontainment method for limiting the escape of genetically engineered organisms used in industrial processes.
Published Extra fingers and hearts: Pinpointing changes to our genetic instructions that disrupt development
(via sciencedaily.com) Original source Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and hearts. Such knowledge opens the door to predictions of which enhancer variants underlie disease in order to harness the full potential of our genomes for better human health.
Published Mystery of moths' warning sound production explained in new study
(via sciencedaily.com) Original source The workings of the ultrasonic warning sounds produced by the wings of a species of moth have been revealed.
Published Down to the core of poxviruses
(via sciencedaily.com) Original source A recent re-emergence and outbreak of Mpox brought poxviruses back as a public health threat, underlining an important knowledge gap at their core. Now, a team of researchers lifted the mysteries of poxviral core architecture by combining various cryo-electron microscopy techniques with molecular modeling.
Published Computer-engineered DNA to study cell identities
(via sciencedaily.com) Original source 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 Microbial division of labor produces higher biofuel yields
(via sciencedaily.com) Original source Scientists have found a way to boost ethanol production via yeast fermentation, a standard method for converting plant sugars into biofuels. Their approach relies on careful timing and a tight division of labor among synthetic yeast strains to yield more ethanol per unit of plant sugars than previous approaches have achieved.
Published Scientists 'break the mould' by creating new colors of 'blue cheese'
(via sciencedaily.com) Original source 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 New technology unscrambles the chatter of microbes
(via sciencedaily.com) Original source Researchers have developed a new search tool to that can match microbes to the metabolites they produce with no prior knowledge, an innovation that could transform our understanding of both human health and the environment.
Published Mechanism discovered that protects tissue after faulty gene expression
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 Disrupted cellular function behind type 2 diabetes in obesity
(via sciencedaily.com) Original source Disrupted function of 'cleaning cells' in the body may help to explain why some people with obesity develop type 2 diabetes, while others do not. A study describes this newly discovered mechanism.
