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.....»»

Mitotic chromosome condensation contributes to the homeostatic control of gene expression regulation
In a collaborative paper in published in the Proceedings of the National Academy of Sciences, Yves Barral with Jorrit Enserink and the Pierre Chymkowitch group in Norway show that the effects on transcription of chromosome condensation during mitosis.....»»
The not so inactive X chromosome
Nearly every cell in our body contains pairs of each of our chromosomes, and these pairs are identical in all but one case: that of our sex chromosomes. Males typically have one X and one Y sex chromosome, while females typically have two X chromosom.....»»

iPhone 14 discounts suggest lower than expected demand in China
Two of China’s biggest smartphone retailers are offering iPhone 14 discounts equivalent to well over $100 – a level of price cut usually restricted to older handsets. One analyst estimates that sales of the four iPhone 14 models were some 28% lo.....»»
Songbird species work together to mob predator owls, but only strike when the time is right
Fleeing isn't the only way by which songbirds can protect themselves against predators. Many songbird species are known to engage in mobbing, where they gather aggressively around a bird of prey, flying rapidly while making stereotypic movements and.....»»

New optical method to verify topological phases in magnetic materials
Topological phases are not restricted to electronic systems. They can also occur in magnetic materials whose properties are described in terms of magnetic waves—or so-called magnons. However, even though scientists have established techniques to ge.....»»
TikTok access from government devices now restricted in more than half of US states
More than half of all US states have partially or fully banned TikTok from government devices, according to a CNN analysis, reflecting a wave of recent clampdowns by governors and state agencies targeting the short-form video app......»»
Noise from urban environments found to affect the color of songbirds" beaks
There is growing concern that anthropogenic noise has various damaging effects on wildlife in urban environments. Urban noise contains a wide range of frequencies, types of sounds such as from traffic, and varying amplitudes including sounds with rap.....»»
Symptoms of illness help pathogens spread among songbirds
It's "Treasure Island" author Robert Louis Stevenson who is credited with coining the phrase "You cannot make an omelet without breaking eggs." For us humans, it's now cliché. For pathogens, these are words to live by. Or, rather, spread by......»»
iOS 16 breaks playback of DRM-restricted content when using HDMI adapters
A few months ago, many users noticed that AirPlay on older Apple TV models no longer works with DRM-restricted content after the iOS 16 update. However, it seems that the problem goes far beyond that, as there are reports that such content can no lo.....»»
Breakthroughs made as scientists sequence the genomes of endangered sharks
The first chromosome level genome sequences for great hammerhead and shortfin mako sharks have shown that both species have experienced major population declines over a 250,000-year history. Low genetic diversity and signs of inbreeding are concernin.....»»
New method to introduce efficient water splitting for hydrogen production at low voltage
Metal oxides are a promising catalyst for photoelectrochemical (PEC) water splitting to produce hydrogen as alternative energy. However, their effectiveness is restricted at low voltage. A research team led by scholars from City University of Hong Ko.....»»
