Dog diversity unveiled by international DNA database //www.koonmotors.com/releases/2023/09/230907130404.htm 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. Thu, 07 Sep 2023 13:04:04 EDT //www.koonmotors.com/releases/2023/09/230907130404.htm Blood-brain barrier governs ant behavior by altering hormone levels //www.koonmotors.com/releases/2023/09/230907130345.htm In many animals, including ants, the blood-brain barrier (BBB) ensures normal brain function by controlling the movement of various substances in and out of the brain. Now, researchers have made the unexpected discovery that the BBB in carpenter ants plays an active role in controlling behavior that's essential to the function of entire ant colonies. The key is production in the BBB of a particular hormone-degrading enzyme. Thu, 07 Sep 2023 13:03:45 EDT //www.koonmotors.com/releases/2023/09/230907130345.htm Genetic tools probe microbial dark matter //www.koonmotors.com/releases/2023/09/230907130329.htm Genetic manipulation of a puzzling, miniscule bacteria that has lived in human mouths at least since the Middle Stone Age is elucidating the genes needed for its unusual lifestyle. These Patescibacteria in the human oral microbiome reside on the surface of another, larger host microbe. Found in many water and land environments, Patescibacteria in general lack the genes required to make many molecules necessary for life, such as the amino acids that make up proteins, the fatty acids that form membranes, and the nucleotides in DNA. This has led researchers to speculate that many of them rely on other bacteria to grow. In a new study, researchers present the first glimpse into the molecular mechanisms behind their relationship with their host cells. They also share details gleaned from fluorescent, time-lapse microsopic imaging of these bacteria as they bud and send out swarms of tiny progeny, only a fraction of which are able to establish a host relationship.

Mon, 28 Aug 2023 16:23:49 EDT //www.koonmotors.com/releases/2023/08/230828162349.htm Unlocking the secrets of cell antennas //www.koonmotors.com/releases/2023/08/230825140357.htm The NSL (non-specific lethal) complex regulates thousands of genes in fruit flies and mammals. Silencing the NSL genes leads to the death of the organism, which gave the complex its curious name. Researchers have now discovered that the genes regulated by the NSL complex also include genes of the intraciliary transport system. This enables different cell types to form cilia on their surface, which are important for cell communication. The study shows that these genes are 'switched on' by the NSL complex, regardless of whether a particular cell has cilia or not. The researchers found that this class of cilia-associated genes is crucial for the function of podocytes. This is a highly specialized cell type of the kidney that, paradoxically, does not have cilia. These findings have important implications for ciliopathies and kidney disease.

The movement of statoliths responding to the inclination relative to the gravity vector is employed for gravity sensing in both plants and animals. However, in plants, the statolith takes the form of a high-density organelle, known as an amyloplast, which settles toward gravity within the gravity sensing cell. Despite the significance of this gravity sensing mechanism, the exact process behind it has eluded scientists for over a century.

In a phenomenon called sexually dimorphic vision, females of some butterfly species perceive ultraviolet color while the males see light and dark. Biologists have discovered that in at least one species, the variation results from a vision gene's jump onto a sex chromosome. It's the first known finding that this kind of genetic change causes sexually dimorphic vision.

But their role in monocot plants remains unexplored. Scientists have now identified OsRALF17 and OsRALF19 in rice and determined their functions in pollen tube germination and growth. This study provides novel insights into the role of RALFs in rice fertilization, paving the way for enhanced grain yield.

Thu, 10 Aug 2023 11:03:13 EDT //www.koonmotors.com/releases/2023/08/230810110313.htm Synthetic antibiotic could be effective against drug-resistant superbugs //www.koonmotors.com/releases/2023/08/230809164729.htm A scientific journey decades in the making has found a new antibiotic strategy to defeat gram-negative bacteria like Salmonella, Pseudomonas and E. coli, the culprits in many urinary tract infections. The synthetic molecule works fast and is durable. It interferes with synthesis of the bacterial outer membrane by jamming an enzyme. When tested against a clinical collection of 285 bacterial strains, including some that were highly resistant to commercial antibiotics, it killed them all.

When cells express RNA, there is always some fluctuation, or noise, in how much RNA is produced. The scientists found several genes whose noise dips below a previously established threshold, known as the noise floor, during expression.
