The cell sentinel that neutralizes hepatitis B
The hepatitis B virus (HBV) is responsible for one of the most serious and common infectious diseases. Transmitted through biological fluids, it attacks the liver cells. The chronic form of the disease can lead to serious complications, including cir.....»»
Damage to cell membranes causes cell aging, finds new study
Our cells are surrounded by a fragile membrane that's only 5 nanometers thick, 1/20 of a soap bubble. Cells are easily damaged by physiological activities, including muscle contraction and tissue injury. To cope with such damage, cells are equipped w.....»»
A new RNA editing tool could enhance cancer treatment
Cell therapies for cancer can be potentially enhanced using a CRISPR RNA-editing platform, according to a new study published Feb. 21 in Cell......»»
Spinning, magnetic micro-robots help researchers probe immune cell recognition
Researchers at the Pritzker School of Molecular Engineering and the Department of Chemistry at the University of Chicago have engineered tiny, spinning micro-robots that bind to immune cells to probe their function. The robot, or "hexapod," gives sci.....»»
The modeling and simulation of self-organized intracellular twisters in the Drosophila oocyte
Cytoplasmic streaming is the large-scale motion of cytoplasm (i.e., gelatinous liquid inside cells) inside a living cell. This flow, known to regulate various intracellular processes, can vary greatly between different cell types at different stages.....»»
Frozen embryos are “children,” according to Alabama’s Supreme Court
IVF often produces more embryos than are needed or used. Enlarge / January 17, 2024, Berlin: In the cell laboratory at the Fertility Center Berlin, an electron microscope is used to fertilize an egg cell. (credit: Getty | Jens Ka.....»»
Physicists develop new solar cell design for better efficiency
Physicists at Paderborn University have used complex computer simulations to develop a new design for significantly more efficient solar cells than previously available. A thin layer of organic material, known as tetracene, is responsible for the inc.....»»
Bat "nightclubs" may be the key to solving the next pandemic
Bats carry some of the deadliest zoonotic diseases that can infect both humans and animals, such as Ebola and COVID-19. In a recently-published article in the journal Cell Genomics, a Texas A&M research team has revealed that some species of bats are.....»»
Junk DNA in birds may hold key to safe, efficient gene therapy
The recent approval of a CRISPR-Cas9 therapy for sickle cell disease demonstrates that gene editing tools can do a superb job of knocking out genes to cure hereditary disease. But it's still not possible to insert whole genes into the human genome to.....»»
Image: Sentinel-1 captures Tobago oil spill
Before and after satellite images from the Copernicus Sentinel-1 mission show the scale of the oil spill that occurred off the shores of Trinidad and Tobago's coastline earlier this week. The ship, identified as The Gulfstream, ran aground and overtu.....»»
Study shows how proteins guide electrons to the right place
Cells need energy to function. Researchers at the University of Gothenburg can now explain how energy is guided in the cell by small atomic movements to reach its destination in the protein. Imitating these structural changes of the proteins could le.....»»
Ancient retroviruses played a key role in the evolution of vertebrate brains, suggest researchers
Researchers report in the journal Cell that ancient viruses may be to thank for myelin—and, by extension, our large, complex brains......»»
Researchers discover that a rare fat molecule helps drive cell death
Columbia researchers have found that a rare type of lipid is a key driver of ferroptosis, a form of cell death discovered by Columbia professor Brent Stockwell......»»
SPNS2 found to be directly exporting S1P for signaling, can be inhibited
When an enemy invades, defenders are ferried to the site to neutralize the marauders. In the human body, a protein carrier called SPNS2 transports S1P molecules from endothelial cells to rally immune cell response in infected organs and tissues......»»
Camera Manufacturer “Silent Sentinel” now Belongs to Motorola Solutions
It looks like the acquisition serves to strengthen the company's approach to security hardware platforms. The post Camera Manufacturer “Silent Sentinel” now Belongs to Motorola Solutions appeared first on Phandroid. Motorola So.....»»
Shell closures spell trouble for hydrogen in a prime passenger-vehicle market
A Shell Oil subsidiary shuttered its light-duty hydrogen fueling station network in California, which could stymie automakers' efforts to make fuel cell vehicles popular in a key market......»»
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.....»»
AI tool predicts function of unknown proteins
A new artificial intelligence (AI) tool that draws logical inferences about the function of unknown proteins promises to help scientists unravel the inner workings of the cell......»»
Nutrients direct intestinal stem cell function and affect aging, finds study
Researchers at the University of Helsinki have discovered a new mechanism of action between the nutrient adaptation of intestinal stem cells and aging. The finding may make a difference when seeking ways to maintain the functional capacity of the agi.....»»
Panasonic inks deal to secure 10,000 tons of graphite for N.A. battery cells
Panasonic Energy entered into an agreement with Australian battery materials supplier Novonix Ltd. that is expected to supply the Japanese battery cell manufacturer with at least 10,000 tons of synthetic graphite, a key material in anodes used in lit.....»»
Trained AI system learns to design cellular materials for tissue engineering, energy storage
Artificial structures called cellular materials have a network of internal spaces within a solid cell-like matrix. Their porous foam-like architecture combines advantages of low density with strength. Researchers at the National Institute for Materia.....»»
