Embryo blood cells are stem cell–independent
The fetal liver is the major hematopoietic organ during the embryonic stage. It is generally believed that hematopoietic hierarchy in the fetal liver is established through the differentiation of fetal hematopoietic stem cells (HSCs). This view assum.....»»
Calcium transport protein in bacteria offers insights for drug development and food safety
Researchers at Umeå University have revealed details on how bacteria use calcium to regulate vital processes in a way that differs from human cells. This breakthrough is significant in the fight against antibiotic resistance and for increasing safet.....»»
Cells From Different Species Can Exchange ‘Text Messages’ Using RNA
Long known as a messenger within cells, RNA is increasingly seen as life’s molecular communication system—even between organisms widely separated by evolution......»»
Ammonia fuel cells see performance gains with new catalyst layer
The pursuit of clean and efficient energy conversion technologies has led to significant advancements in fuel cell research. A study conducted at Fuzhou University and published in Frontiers in Energy, presents a novel approach to enhance the perform.....»»
Scientists develop a new method to study gene function in cells and tissue
The Gaublomme lab has developed a new optical pooled screening approach called CRISPRmap, which enables the coupling of optical properties of single cells to targeted genetic perturbations. Optical phenotypes are typically inaccessible for sequencing.....»»
Study proposes that proteins can compartmentalize and form droplets inside cells
In physics, a system composed of two substances can be modeled in accordance with classical mixture theory, which considers the fraction corresponding to each constituent and the interactions among constituents. Examples include the coexistence of hi.....»»
Plant stem cells: Understanding the biological mechanism of growth control
Researchers from the University of Freiburg have identified the HAN molecule as an important regulator that controls plant growth in conjunction with WOX5. Understanding this mechanism is relevant for breeding more resilient or higher-yielding crops......»»

Researchers at LMU University Hospital have discovered a new molecular switch that protects against cell death......»»
Expansion technique to image nanoscale structures inside cells makes high-resolution imaging more accessible
A classical way to image nanoscale structures in cells is with high-powered, expensive super-resolution microscopes. As an alternative, MIT researchers have developed a way to expand tissue before imaging it—a technique that allows them to achieve.....»»
Signaling pathway discovery could lead to faster, more reliable human stem cell differentiation
A recent discovery has found a possible avenue to improve human health by better understanding how to engineer human stem cell differentiation......»»
Key gene discovered for regulating rice grain length
Recently, a research team led by Professor Wu Yuejin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences, discovered a key gene that can influence rice grain length by regulating cell proliferation, the RGL2 gene. This pr.....»»
Claustrophobic cells slow their own growth, forming beautiful patterns of concentric circles
Like so many organisms on the planet, when cells experience mosh-pit-level crowding, they may just become stressed. Yet unlike most other life forms, cells subject to physical stress from crowding by neighbors can find some relief by dramatically slo.....»»
Advanced model predicts gene architecture via nucleosome position
DNA—the molecule that carries the genetic information of all living organisms—is packaged within cells in a complex manner that allows it to function efficiently. Nucleosomes facilitate DNA compaction and also play a crucial role in regulating ge.....»»
From chaos to structure: How a bunch of seemingly disorganized cells go on to form a robust embryo
Pipetting liquids into tiny test tubes, analyzing huge datasets, poring over research publications—all these tasks are part of being a scientist. But breaking this routine is essential. Time away from the usual work environment can spark creative i.....»»
An independent panel reports findings into loss of marine life off the North East and Yorkshire coast
An independent expert panel has today (20 January) published its findings into the loss of marine life off the North East and Yorkshire coast. It follows a series of mass mortalities of crabs and lobsters that were recorded along the Northeast and No.....»»
Scientists explore whether smaller chromosomes lead to more segregation errors during egg cell division
Three RIKEN researchers have shed light on the cellular mechanisms underlying chromosomal abnormalities that can cause miscarriages and congenital disorders such as Down syndrome......»»
Sludge sequencing: High-throughput single-cell method reveals novel species and genetic diversity
Activated sludge is essential for removing contaminants from wastewater, and understanding the diverse microbial communities it harbors has been a significant task. Traditional methods fail to capture the full spectrum of microbial interactions. Due.....»»
GM ditches failed Ultium battery branding as its EV sales soar
GM says it's time to embrace new cell formats and chemistries. General Motors is shaking up its electric vehicle strategy once again. Despite bumper EV sales in 2024, the US autom.....»»
General Motors is ditching Ultium branding for its EV batteries
GM says it's time to embrace new cell formats and chemistries. General Motors is shaking up its electric vehicle strategy once again. Despite bumper EV sales in 2024, the US autom.....»»
You get your energy from your mom. A new study explains why
It's one of the basic tenets of biology: We get our DNA from our mom and our dad. But one notable exception has perplexed scientists for decades: Most animals, including humans, inherit the DNA inside their mitochondria—the cell's energy centers—.....»»
How Chlamydia pneumoniae bacteria use molecular mimicry to manipulate the host cell
Bacteria that cause diseases, so-called pathogens, develop various strategies to exploit human cells as hosts to their own advantage. A team of biologists from Heinrich Heine University Düsseldorf (HHU), together with medical professionals and exper.....»»
