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.....»»
Genes spatially organize for efficient mRNA splicing, study shows
The nucleus of each of your cells contains all the genetic information (the genome) necessary to build every type of cell and protein in your entire body. Like a complex library in a tiny space 50 times smaller than the width of a human hair, genes a.....»»

Shaping up how red blood cell deformability is assessed—researchers develop new approach
Red blood cells (RBCs) transport oxygen throughout the body and are able to pass through a complex of narrow capillaries due to their ability to deform. "The deformability of RBCs is an important indicator of their health and functionality, and chang.....»»
"Lost" spy satellite orbited Earth undetected for 25 years—until now, scientists say
An experimental spy satellite that was deemed "lost" after eluding detection for decades has finally been found. "The S73-7 satellite has been rediscovered after being untracked for 25 years," astrophysicist Jonathan McDowell said in an April 29 post.....»»
Apple loses another designer who worked in Jony Ive"s core team
Duncan Kerr, a designer who has been a part of Apple's journey since the late 1990s is now departing, marking another loss for the design team in a relatively short span of time.Jony IveIn February, Apple lost designer Bart Andre, who had been with t.....»»
Researchers discover new function of oncoproteins
Researchers at the University of Würzburg have discovered a new function of the oncoprotein MYCN: It not only helps cancer cells to grow stronger, but also makes them more resistant to drugs. The study is published in Molecular Cell......»»
New technology changes how proteins in individual cells are studied
Researchers from Karolinska Institutet, together with Pixelgen Technologies, have developed and applied a technique that makes it possible to map proteins in individual cells in a completely new way. Not only is it now possible to measure the amount.....»»
Study pinpoints cellular response to pressure in sea star embryos
An international team of scientists has discovered a new cellular mechanism that explains how cells can adapt to pressure changes during tissue growth by packing themselves into a unique shape......»»
FTX customers to get their money back in full (with asterisk) [U]
Update: A court filing has confirmed that the company now has more than enough money to repay customers. In recognition of the lost gains, creditors owed $50k or less will receive around 118% of their deposit value at the time of the Chapter 11 filin.....»»
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.....»»
What are nanoplastics? An engineer explains concerns about particles too small to see
It's become common to read that microplastics—little bits of plastic, smaller than a pencil eraser—are turning up everywhere and in everything, including the ocean, farmland, food and human bodies. Now a new term is gaining attention: nanoplastic.....»»
Study reveals differences in DNA folding between neurons and other brain cells, links them to cell functions
Researchers from Skoltech and their colleagues have investigated nerve cell regulation. Mounting knowledge of regulation mechanisms could enable a better understanding of how the healthy brain operates and what goes wrong in developmental and oncolog.....»»
Study sheds light on cancer cell "tug-of-war"
Understanding how cancerous cells spread from a primary tumor is important for any number of reasons, including determining the aggressiveness of the disease itself. The movement of cells into the extracellular matrix (ECM) of neighboring tissue is a.....»»
Decoding development: mRNA"s role in embryo formation
A new study at Hebrew University reveals insights into mRNA regulation during embryonic development. The study sheds light on the intricate process of mRNA regulation during embryonic development, providing novel insights into how pluripotent cells a.....»»
Free-forming organelles help plants adapt to climate change
Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery......»»
Seeing is believing: Observation of migrasomes
Migrasomes, novel organelles first reported by Professor Li Yu' s team in 2015, are vesicular structures with diameters ranging from 0.5 to 3 micrometers that form on the retraction fibers at the rear of migrating cells. These structures contain vari.....»»
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.....»»
