Chromosome positioning during sperm differentiation described
Chromosomes occupy specific regions of the cell nucleus called chromosome territories. In somatic cells, scientists have observed that there is a correlation between this positioning and genome regulation. In fact, alterations in chromosome distribut.....»»
Dell responds to return-to-office resistance with VPN, badge tracking
Report claims new tracking starts May 13 with unclear consequences. Enlarge (credit: Getty) After reversing its positioning on remote work, Dell is reportedly implementing new tracking techniques on May 13 to ensure its.....»»
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.....»»
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.....»»
How a "conductor" makes sense of chaos in early mouse embryos
Early embryonic development is tumultuous. It involves a rapid sequence of events, including cell division, differentiation, and lots of compartments moving around within each cell. Like an orchestra performance where each member of the band must sta.....»»
Designing a novel substrate for myogenic differentiation from induced pluripotent stem cells
Since their discovery, researchers have repeatedly demonstrated the potential medical applications of differentiated cells and tissues generated from induced pluripotent stem (iPS) cells. However, a significant hurdle to real-world medical applicatio.....»»
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.....»»
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.....»»
Researchers clarify cryptic differentiation within enigmatic hemiparasitic love vine Cassytha filiformis
The widespread hemiparasitic Lauraceae genus Cassytha currently contains 19 described species, one variety and four forms. This genus is controversial and has not been satisfactorily resolved. Cassytha filiformis is cosmopolitan in tropical and subtr.....»»
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.....»»
Fiat 500e braves Miami traffic but faces uphill sales battle
Fiat is positioning the electric 500e as a city car meant for quick trips, but persuading Americans to buy a small EV could be a challenge......»»
Using one single image to realize on-orbit calibration of space camera lens distortion
In various space tasks such as space rendezvous-docking and on-orbit maintenance, the measurement of the relative posture and position of non-cooperative spacecraft is a key component. However, the commonly used global positioning system, radar detec.....»»
Using suction cups inspired by fish to listen in on whale conversations
In their ambitious goal to understand and ultimately communicate with sperm whales, research scientists from Project CETI have enlisted the help of unlikely collaborators—clingfish......»»
Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale
UBC researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population......»»
NASA lights "beacon" on moon with autonomous navigation system test
For 30 total minutes in February, NASA lit a beacon on the moon—successfully testing a sophisticated positioning system that will make it safer for Artemis-era explorers to visit and establish a permanent human presence on the lunar surface......»»
New discovery reveals how the egg controls sperm entry
After the egg has been fertilized by a sperm, the surrounding egg coat tightens, mechanically preventing the entry of additional sperm and the ensuing death of the embryo. This is according to a new study led by researchers at Karolinska Institutet a.....»»
A novel strategy to efficiently distinguish subtype-specific cardiomyocytes from human iPS cells
In a recent study led by Associate Professor Yoshinori Yoshida (Department of Cell Growth and Differentiation) and published in Communications Biology, a team of researchers identified CD151 as a marker for distinguishing subtype-specific cardiomyocy.....»»
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.....»»
