Peculiarities of the germline-restricted chromosome of songbirds
In multicellular organisms, all cells of an individual normally contain the same genetic information and cell differentiation is achieved through regulation of gene expression. There are exceptions, however, where, instead of silencing, certain seque.....»»
Hybrid songbirds found more often in human-altered environments
Hybrids of two common North American songbirds, the black-capped and mountain chickadee, are more likely to be found in places where humans have altered the landscape in some way, finds new University of Colorado Boulder research......»»
Nestling birds recognize their local song "dialect"
A recent study, published in Current Biology, led by researchers at Stockholm University and Uppsala University, has shown that juvenile songbirds react to hearing the songs they will eventually produce as adults, even when they are as young as 12 da.....»»
Q&A with a chromosome cartographer
La Jolla Institute for Immunology Associate Professor Ferhat Ay, Ph.D., is building some of the world's smallest maps. Dr. Ay harnesses computers to transform DNA genomic sequences into 3D maps. These maps can reveal how genes interact and how the bo.....»»
Quaternary ammonium disinfectant exposure promotes bacterial antibiotic resistance in soils
As antibiotics are restricted or even banned in animal production, more disinfectants are used to maintain adequate sanitation to prevent bacterial diseases. The usage of disinfectant is more than that of antibiotics, especially during the flu pandem.....»»
Chromosome-scale genome of a gentle giant enables insights into the genetic health of a threatened population
The Aldabra giant tortoise is one of only two giant tortoise species left in the world, and it is currently on the threatened list. Conservation efforts are underway, but more and better tools to improve the chance of long-term success are greatly ne.....»»
Viruses knowledge unlocked by new metagenomics technologies
Metagenomic sequencing techniques allows the study of microbiomes from all sorts of habitats, and using this to explore phages (bacteriophage genomes integrated into the circular bacterial chromosome) has expanded knowledge of viruses that integrate.....»»
Synergistic catalysts for high-efficiency hydrogen storage
Hydrogen energy is regarded as promising renewable energy. However, the development of hydrogen energy is restricted by the safe and efficient storage and transportation of hydrogen. Therefore, it remains challenging to explore the feasibility of hig.....»»
Relationship between song order and rhythmical timing in songbirds
An international collaboration between musicians and birdsong scientists has found that in the Australian pied butcherbird songs surveyed, the order of song elements is strongly related to rhythmical timing......»»
Plant breeding: Using "invisible" chromosomes to pass on packages of positive traits
The ideal crop plant is tasty and high-yielding while also being resistant to diseases and pests. But if the relevant genes are far apart on a chromosome, some of these positive traits can be lost during breeding. To ensure that positive traits can b.....»»
Can Conversational AI Improve the Online Retail Experience?
The pandemic, which largely restricted physical interaction, meant that both retailers and consumers had to learn and adapt to digital communication tools. Continue reading........»»
How songbirds" striking colors put them at risk
Bright, uniquely colored songbirds are at higher risk of extinction and more likely to be traded as pets, according to researchers reporting in Current Biology on September 15. The researchers also predict that almost 500 additional bird species, mos.....»»
Full-screen widgets are coming to a future Windows 11 update
After being restricted to a window, widgets are being expanded to a much bigger view in an upcoming update......»»
Researchers engineer first sustainable chromosome changes in mice
Evolutionary chromosomal changes may take a million years in nature, but researchers are now reporting a novel technique enabling programmable chromosome fusion that has successfully produced mice with genetic changes that occur on a million-year evo.....»»
Tesla, Nio suspend EV charging services as China power cuts bite
Tesla turned off or restricted services at more than a dozen super-charging stations in the two cities, leaving just two still in operation and only during the night as of Aug. 17, local media reported.....»»
Bold New Jersey Shore Flood Rules Could Be Blueprint for Entire U.S. Coast
Coastal flood zones where development is restricted will be based on future climate change projections, not past floods.....»»
At Some Colleges, the Fall of Roe Will Weaken Student Health Care
As students return to school, many will find restricted campus access to abortion services and information—and perhaps reproductive care in general......»»
Power restriction in western China has little impact on panel supply
The provincial government of Sichuan, western China, restricted power supply to local factories during August 15-20 and this will have a little substantial impact on overall supply of display panels, industry experts analyzed......»»
Best phone VPN in 2022

Speeding up evolution at the genome level by alternative chromosome configuration
A research team led by André Marques at the Max Planck Institute for Plant Breeding Research in Cologne, Germany, has uncovered the profound effects of an atypical mode of chromosome arrangement on genome organization and evolution. Their findings a.....»»
A key process in asymmetric cell division preserves the immortality of the germline
During cell division, chromosomes are replicated into two copies—one for each daughter cell. These copies, called sister chromatids, are usually considered identical. In fact, it's the two pairs of sister chromatids that make up the symmetrical X s.....»»
