Simulating the shear destruction of red blood cells
Many medical devices for treating heart failure generate nonphysiological shear flow. This can trigger the destruction of red blood cells after implantation of ventricular assist devices (VADs), artificial heart valves, vascular stents, or interventi.....»»
How bacteria actively use passive physics to make biofilms
When we think about bacteria, we may imagine single cells swimming in solution. However, similarly to humans, bacterial cells often socialize, using surfaces to coalesce into complex heterogeneous communities called biofilms. Within a group, bacteria.....»»
Researchers aim to control gene expression by studying the memories of cells
Communication between cells is now believed to activate a memory mechanism that sustains gene expression, a finding based on the work of Dr. Gregory Reeves......»»
GM has long history of partnering with rivals including Hyundai
An alliance with Honda has lasted for more than two decades and resulted in production of hydrogen fuel cells and electric vehicles, but some other tie-ups quickly fizzled......»»

"Staggering" destruction in Yemen after deadly flash flooding
Sitting by their ruined home, Abu Ibrahim wept for his son and seven grandchildren killed by flash floods in Yemen, where increasingly severe downpours are piling more misery on the impoverished, war-torn country......»»
Human "molecular map" contributes to the understanding of disease mechanisms
Scientists at Weill Cornell Medicine in Qatar (WCM-Q) have created an intricate molecular map of the human body and its complex physiological processes based on the analysis of thousands of molecules in blood, urine and saliva samples from 391 volunt.....»»
Study reviews ginsenoside biosynthesis and regulation in Panax notoginseng
Panax notoginseng, a perennial herb central to traditional Chinese medicine, is celebrated for its health benefits, such as promoting blood circulation and reducing inflammation. Its key components, ginsenosides, are associated with various pharmacol.....»»
Beyond needles: Introducing a new, nature-based approach for delivering cargo into egg cells
A new approach for delivering miniature research tools into the interior of egg cells and embryos has been developed at the Marine Biological Laboratory (MBL), resolving a major bottleneck to using the gene-editing tool CRISPR-Cas9 in many research o.....»»
Experimental nanomedicine delivers chemo drugs directly to tumors in mice
Researchers at the University of Chicago Medicine Comprehensive Cancer Center have developed a nanomedicine that increases the penetration and accumulation of chemotherapy drugs in tumor tissues and effectively kills cancer cells in mice......»»
Pausing biological clock could give boost to lab-produced blood stem cells
A decade ago, Raquel Espin Palazon discovered that inflammatory signaling pathways must switch on for embryos to produce blood stem cells. The latest work from her lab shows the potential value of keeping those same signals switched off after their i.....»»
Silver nanoparticles and a new sensing method can fight back against antibiotic-resistant biofilms
From safeguarding our food supply to preventing hospital infections, the battle against antibiotic-resistant bacteria is a growing challenge. Some bacteria can form biofilms, thick aggregates of millions of individual cells surrounded by protective m.....»»
How to merge and unmerge cells in Microsoft Excel
Microsoft Excel has numerous powerful data analysis functions, but sometimes you need to do something simple like merge some cells. Here's how......»»
Biomolecules inside living cells can now be seen with infrared light thanks to new method
To accelerate biotechnology innovations, such as the development of lifesaving drug therapies, scientists strive to develop faster, more quantitative and more widely available ways to observe biomolecules in living cells......»»
Uncovering the unique roles of Exportin-5 in RNA export within Drosophila cells
Eukaryotic cells are complex biological units, each with multiple membrane-bound compartments. These cells use specialized mechanisms to export biomolecules from their synthesis site to where they function......»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»

Hijacking the command center of the cell: Nuclear parasites in deep-sea mussels
Most animals live in intimate relationships with bacteria. Some of these bacteria live inside the cells of their hosts, but only very few are able to live inside cell organelles (structures inside the cell, like organs in the body). One group of bact.....»»
Decoding the language of cells with the power of proteomics
Hundreds of millions of years ago, single cells joined forces to become multicellular organisms. At the foundation of this multicellular world is the cell surface: the plasma membrane surrounding each cell, where individual units meet and communicate.....»»
Space-based experiments could help to advance early cancer detection through blood tests
Imagine a sensor so sensitive it can detect early cancer in a single drop of blood, enabling diagnosis and treatment before the first symptoms—possibly before a tumor even forms......»»
BMW explains why it will sell hydrogen fuel cells in 2028
BMW sees hydrogen as complementary to battery EVs on a region-by-region basis. Enlarge / BMW has had some hydrogen fuel cell-powered iX5s in testing for a while, and for Art Basel 2024 this one got a new look courtesy of Es Devli.....»»
