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.....»»
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.....»»
Researchers develop near-chromosome-level genome for the Mojave poppy bee
Scientists at the United States Department of Agriculture (USDA)'s Agricultural Research Service (ARS) and university research partners have developed a near chromosome-level genome for the Mojave poppy bee, a specialist pollinator of conservation co.....»»
First chromosome-level reference genomes of the ornamental banana and pink banana
The genus Musa, encompassing approximately 70 herbaceous species, is predominantly found in the tropical and subtropical regions of Asia and Oceania. This genus is renowned for being one of the most important food crops globally and popular ornamenta.....»»
Unveiling the genetic blueprint of safflower
A research team has completed a high-quality chromosome-scale assembly of the Chuanhonghua 1 safflower genome. This work sheds light on the genetic underpinnings of crucial traits like linoleic acid (LA) and hydroxysafflor yellow A (HSYA) production......»»
Social change may explain decline in genetic diversity of the Y chromosome at the end of the Neolithic period
The emergence in the Neolithic of patrilineal social systems, in which children are affiliated with their father's lineage, may explain a spectacular decline in the genetic diversity of the Y chromosome observed worldwide between 3,000 and 5,000 year.....»»
It’s cutting calories—not intermittent fasting—that drops weight, study suggests
The study is small and imperfect but offers more data on how time-restricted diets work. Enlarge (credit: Getty | David Jennings) Intermittent fasting, aka time-restricted eating, can help people lose weight—but the r.....»»
Twisted pollen tubes induce infertility in plants with multiple sets of chromosomes
Most mammals and humans have a double set of chromosomes—and as a rule, plants do, too: One set comes from the father, the other from the mother. Such organisms are called diploids. However, sometimes the number of chromosome sets doubles from one.....»»
New study finds potential targets at chromosome ends for degenerative disease prevention
We depend on our cells being able to divide and multiply, whether it's to replace sunburnt skin or replenish our blood supply and recover from injury. Chromosomes, which carry all of our genetic instructions, must be copied in a complete way during c.....»»
Female zebra finches seek mate who sings one song just right
Humans aren't the only living beings who find a singing voice attractive in the opposite sex—songbirds do too. For about a third of the approximately 4,000 songbird species that sing only one song, the features that make these tunes alluring to a p.....»»
Google Photos’ best AI editing tools will soon be free for everyone
Once restricted to Pixel phones and paying Google One subscribers, many of Google Photos' best AI editing tools will soon be free for everyone......»»

Age verification should be Apple’s job, says Tinder parent Match
Meta CEO Mark Zuckerberg has argued that for age-restricted apps, age verification should be Apple’s job. He’s now been joined in this view by the new head of trust and safety at Match, the company behind leading dating apps like Tinder, Hinge, O.....»»
Horizontal gene transfer: How fungi improve their ability to infect insects
Researchers at the Kiel Evolution Center have investigated for the first time in detail how a fungus important for biological plant protection can pass on an advantageous chromosome horizontally, using a previously little-studied way of exchanging ge.....»»
Identiv ScrambleFactor provides privacy and security in restricted access environments
Identiv introduces ScrambleFactor, an addition to its high-security physical access control system (PACS) portfolio. The ScrambleFactor reader reimagines secure entry for the federal market with fingerprint biometrics and a LCD touchscreen keypad, in.....»»
Similar genetic elements underlie vocal learning in mammals
The vocalizations of humans, bats, whales, seals and songbirds vastly differ from each other. Humans and birds, for example, are separated by some 300 million years of evolution. But scientists studying how these animals learn to "speak" have time an.....»»
Double trouble at chromosome ends: New study alters our understanding of telomere biology
Half a century ago, scientists Jim Watson and Alexey Olovnikov independently realized that there was a problem with how our DNA gets copied. A quirk of linear DNA replication dictated that telomeres that protect the ends of chromosomes should have be.....»»
New insights in the regulation of genetic information exchange
Within every cell in our body, our DNA is tightly bundled with proteins to form structures known as chromosomes. The commonly known shape of a chromosome relates to an X-shaped appearance in many organisms. The formation of the X-shaped chromosome re.....»»
Apple handed a victory in Apple Watch antitrust lawsuit with AliveCor
Apple has been handed a victory in its ongoing legal battle with AliveCor over the Apple Watch’s heart monitoring technology. AliveCor had alleged that Apple restricted third-party access to certain Apple Watch heart rate data, a move that it d.....»»
