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.....»»
What will it take to save the regent honeyeater?
New research from The Australian National University (ANU) shows that unless conservation actions are urgently stepped up, one of our most beautiful songbirds, the regent honeyeater, will be extinct within 20 years......»»
Exogenous artificial DNA forms chromatin structure with active transcription in yeast
Previously, researchers from Tianjin University designed and created a 254 kb digital data carrying artificial chromosome in yeast. This work "is a key proof-of-concept that demonstrated how artificial chromosomes can be used for data storage in a wa.....»»
Sauropod dinosaurs were restricted to warmer regions of Earth
Giant, long-necked sauropods, thought to include the largest land animals ever to have existed, preferred to live in warmer, more tropical regions on Earth, suggesting they may have had a different physiology from other dinosaurs, according to a new.....»»
Evergrande Has Defaulted On Its Debt
Evergrande, the embattled Chinese property developer, has defaulted on its debt, according to Fitch Ratings. From a report: The credit ratings agency on Thursday downgraded the company and its subsidiaries to "restricted default," meaning that the fi.....»»
Researchers identify key RNA "gatekeeper" in gene expression, pointing to possible new drug targets
Researchers have identified the first non-coding RNA that controls formation of chromosome loops, which govern gene expression. Jpx RNA was previously thought to be involved only in X chromosome inactivation, a necessary step in development of female.....»»
Researchers identify key RNA "gatekeeper" in gene expression, pointing to possible new drug targets
An important player in the healthy development of female embryos turns out also to play a key role in regulating the behavior of chromosome loops and gene expression in both sexes, according to a new study by researchers at Massachusetts General Hosp.....»»

SAN JOSE, Calif.–(BUSINESS WIRE)–Energous Corporation (Nasdaq: WATT), a leading developer of RF-based charging for wireless power networks, today announced it has issued inducement restricted stock units (“RSUs”) to three new, non-exe.....»»
How eating less in early life could help with reproduction later on
New research shows how switching from a restricted diet to eating as much as you like could be beneficial for reproduction in later life. Researchers studied the eating and mating habits of the small fruit fly Drosophila melanogaster. They found that.....»»

Switching from a restricted diet to eating as much as you like could be beneficial for reproduction in later life, according to new research from the University of East Anglia......»»
Researchers identify a protein that enables communication between the germline and the rest of the body
A recent study by the Monash Biomedicine Discovery Institute (BDI) using roundworms has discovered that a conserved syndecan protein coordinates communication between the germline and the rest of the body and that this communication mechanism is requ.....»»
Brydge Max+ keyboard for 11-inch iPad Pro, iPad Air now available
The Brydge Max+ keyboard and trackpad accessory is now available for Apple's 11-inch iPad Pro, as well as the fourth-generation iPad Air.Credit: BrydgeBrydge first debuted the Max+ keyboard earlier in 2021, though the accessory was restricted to the.....»»
Xist marks the spot: How an RNA molecule silences the X chromosome
In one of the mysteries of mammalian development, every cell in the early female embryo shuts down one of its two copies of the X chromosome, leaving just one functional. For years, the mechanics behind this X chromosome inactivation have been murky,.....»»
Study reveals that diet restricted size of hunter-gatherer societies
Short growing seasons limited the possible size of hunter-gatherer societies by forcing people to rely on meat, according to a recent study by a team of international reseachers including McGill University professor Eric Galbraith. .....»»
"Useless Specks of Dust" Turn Out To Be Building Blocks of All Vertebrate Genomes
An anonymous reader quotes a report from ScienceAlert: Originally, they were thought to be just specks of dust on a microscope slide. Now, a new study suggests that microchromosomes -- a type of tiny chromosome found in birds and reptiles -- have a l.....»»
Looking for musical abilities in primates
Songbirds share the human sense of rhythm, but it is a rare trait in non-human mammals. An international research team led by senior investigators Marco Gamba from the University of Turin and MPI's Andrea Ravignani set out to look for musical abiliti.....»»
Biologists" artificial chromosomes study sheds light on gene therapies
A research team led by Dr. Karen Wing Yee Yuen, Associate Professor from the School of Biological Sciences at the University of Hong Kong (HKU), revealed the mechanism of artificial chromosome (AC) formation in the embryos of the model organism Caeno.....»»
Supercomputers reveal how X chromosomes fold, deactivate
Using supercomputer-driven dynamic modeling based on experimental data, researchers can now probe the process that turns off one X chromosome in female mammal embryos. This new capability is helping biologists understand the role of RNA and the chrom.....»»
The first coronavirus lockdown revealed big behavioral gender differences
In a crisis, women make significantly longer phone calls and adhere more closely to governmental measures than men; men are less willing to have their mobility restricted and return to normal more quickly than women. Researchers at the Complexity Sci.....»»
When a chromosome is lost: How do human cells react to monosomy?
Human cells are usually diploid—they contain two sets of chromosome. Cells in which one chromosome is missing from the duplicated chromosome set are generally not viable. For a long time, the mechanisms responsible for the loss of viability were un.....»»
