One way genetic mutations occur during formation of eggs and sperm
Investigators have employed mutant mice to study how the accumulation of genetic errors is managed during egg and sperm formation......»»
The genetic basis and process of inbreeding depression in an elite hybrid rice
Inbreeding depression is defined as reduced fitness or performance arising from increasing homozygosity of progenies due to successive inbreeding, whereas heterosis refers to the superiority of a hybrid over its parent resulting from the increase in.....»»
Research reveals key genetic factors in snap bean pod traits
Snap beans, the vegetable form of the common bean (Phaseolus vulgaris), are cultivated for their tender, immature pods. They boast a diverse array of pod shapes and sizes. Pod morphology, including shape, thickness, length, and color, plays a crucial.....»»
Into the abyss: Understanding black hole formation through natal kicks and neutrino emission
A new study in Physical Review Letters explores the conditions of black hole formation from dying stars, particularly the role of neutrino-induced natal kicks in the formation process......»»
Study shows regenerating worms have genetic control over their algal partners
Many organisms are far more complex than just a single species. Humans, for example, are full of a variety of microbes. Some creatures have even more special connections, though......»»
Study reveals insights into protein evolution
Rice University's Peter Wolynes and his research team have unveiled a breakthrough in understanding how specific genetic sequences, known as pseudogenes, evolve. Their paper was published May 13 in the Proceedings of the National Academy of Sciences......»»
Evolutionary history shapes variation of wood density: Study
Ecology and evolutionary biology suggest that closely related species are more likely to exhibit morphological and functional similarities compared to distantly related species. Each tree species represents a unique genetic reservoir and is a product.....»»
Long-term study finds organic farming leads to adaptations in the genetic material in plants
Plants adapt genetically over time to the special conditions of organic farming. This has been demonstrated in a long-term study conducted at the University of Bonn......»»
Researchers reveal how genetically identical water fleas develop into different sexes
Daphnia are tiny crustaceans, or "water fleas," that are extremely adaptable to their environment. This is due to their remarkable phenotypic plasticity, i.e., their ability to change their form or behavior despite their genetic makeup remaining unch.....»»
Researchers breed tomato plants that contain the complete genetic material of both parent plants
In a new study published in Nature Genetics, led by Charles Underwood from the Max Planck Institute for Plant Breeding Research in Cologne, Germany, scientists established a system to generate clonal sex cells in tomato plants and used them to design.....»»
Monster galactic outflow powered by exploding stars
Star death and birth both contribute to driving material out of a galaxy. Enlarge / All galaxies have large amounts of gas that influence their star-formation rates. (credit: NASA, ESA, CSA, and J. Lee (NOIRLab)) Galaxie.....»»
More children gain hearing as gene therapy for profound deafness advances
The therapy treats a rare type of deafness, but experts hope it's a "jumping point." Enlarge / Opal Sandy (center), who was born completely deaf because of a rare genetic condition, can now hear unaided for the first time after r.....»»
Team develops efficient host-vector system for a model archaeon by solving CRISPR-based host-plasmid conflict
A research group has constructed versatile genetic tools for Saccharolobus islandicus REY15A, one of the very few archaeal models for archaea biology and CRISPR biology research......»»
Genes spatially organize for efficient mRNA splicing, study shows
The nucleus of each of your cells contains all the genetic information (the genome) necessary to build every type of cell and protein in your entire body. Like a complex library in a tiny space 50 times smaller than the width of a human hair, genes a.....»»
Genetic study finds early summer fishing can have an evolutionary impact, resulting in smaller salmon
Atlantic salmon are caught by fisheries when the fish are migrating to spawn. A new study led by the University of Helsinki explored how salmon caught at different times during their spawning migration differ from each other genetically. The study on.....»»
AI simulation of flavored vape reactions reveals formation of many hazardous chemicals
New research has uncovered the potentially harmful substances that are produced when e-liquids in vaping devices are heated for inhalation. The study, published in Scientific Reports, highlights the urgent need for public health policies concerning f.....»»
Study underscores new strategies to fight drug-resistant bacteria
Several billion years ago, a genetic arms race began between bacteria and their viral killers. This seemingly eternal struggle continues today, with implications for diseases killing tens of thousands of people around the world each year......»»
Researchers study the intricacies of homologous recombination and abnormal chromosome bridges
Keeping the genetic information stored in genomic DNA intact during the cell division cycle is crucial for almost all lifeforms. Extensive DNA damage invariably causes various adverse genomic rearrangements, which can lead to cell death in the best c.....»»
New Vincetoxicum species found in Yunnan
Vincetoxicum is a genus of plants in the Apocynaceae family. It is distributed in Asia, especially in mountainous areas, and most of the known species occur in China and Japan. The extended Vincetoxicum includes about 150 species. In recent years, ne.....»»
Using algorithms to decode the complex phonetic alphabet of sperm whales
The allure of whales has stoked human consciousness for millennia, casting these ocean giants as enigmatic residents of the deep seas. From the biblical Leviathan to Herman Melville's formidable Moby Dick, whales have been central to mythologies and.....»»
Study identifies early warning signals for the end of the African humid period
The transition from the African humid period (AHP) to dry conditions in North Africa is the clearest example of climate tipping points in recent geological history. They occur when small perturbations trigger a large, non-linear response in the syste.....»»
