A new Achilles heel of the bacterial cell wall
The bacterial cell wall must be constantly remodeled in order to grow and divide. This involves the close coordination of lytic enzymes and peptidoglycan synthesis. In their study published in Nature Communications, researchers led by Martin Thanbich.....»»
Optogenetic control reveals collective cell behavior
New research led by the Institute for Bioengineering of Catalonia (IBEC) has studied the migratory movement of groups of cells using light control. The results show that there is no leader cell that directs the collective movement, as previously thou.....»»
Scientists discover how TGF-Beta sends its message even while tethered to the cell membrane
For years, scientists have thought that TGF-Beta, a signaling protein that holds sway over an astonishing array of cellular processes from embryonic development to cancer, could only do its work once it escaped a lasso-like "straitjacket.".....»»
Modified nano-sized cell particles found to boost cancer immunotherapy, reduce side effects
Immunotherapy is a type of cancer treatment that uses the body's own immune system to help fight cancer. This is by stimulating the immune response to recognize and attack cancer cells more effectively. The treatment involves using substances that bo.....»»
Beyond displays: Liquid crystals in motion mimic biological systems
Liquid crystals are all around us, from cell phone screens and video game consoles to car dashboards and medical devices. Run an electric current through liquid crystal displays (LCDs) and they generate colors, thanks to the unique properties of thes.....»»
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.....»»
Tubular scaffolds boost stem cell-driven bone regeneration in skull defects
Scientists from Sun Yat-sen University's School of Biomedical Engineering have developed tubular scaffolds made from electrospun membranes, which significantly enhance bone regeneration in critical skull defects......»»

Battery EVs vs fuel-cell EVs: Could hydrogen power your next car?
While battery EVs have a huge lead, there are still plenty of proponents of hydrogen EVs, or fuel-cell EVs. Could FCEVs actually take over? Well, probably not......»»
Unlocking plant defense: Bacterial hijacking exposed
Bacterial wilt caused by Ralstonia solanacearum poses a severe threat to agriculture worldwide, affecting numerous crops. The pathogen's arsenal of type III effectors (T3Es) enables it to manipulate host defense mechanisms, aiding infection. One majo.....»»
Researchers examine protein arrangement in cell membrane that triggers programmed cell death
How can molecular structures be analyzed when the resolution of the techniques available is not sufficient? Researchers from the fields of physics, chemistry and medicine at Heinrich Heine University Düsseldorf (HHU) have combined and further develo.....»»
Studying fungi"s "weak link" to fight global rise in deadly fungal infections
A group of scientists at the Department of Energy's Oak Ridge National Laboratory have conducted neutron scattering research to reveal key information about fungus cell membranes that could aid in developing new antifungal treatments......»»
Research team achieves high-resolution 2D imaging for graphene devices under high pressure
A research team led by Prof Zhang Zengming from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has combined nitrogen-vacancy (NV) centers in diamond with a diamond anvil cell (DAC) to achieve non-inv.....»»
Glitch in protein synthesis could affect tumor growth
During protein synthesis, or translation, genetic information transcribed in the cell's mRNA directs the stringing together of amino acids—the building blocks of proteins. As the translation machinery carouses along the string of nucleotides that m.....»»
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.....»»
Pottery shards provide insight into the lives and trade networks of enslaved people in the Cayman Islands
Ph.D. candidate Elysia Petras and archaeologist Dr. Brandi MacDonald recently discovered 15 shards of Afro-Caribbean pottery ware at Jackson Wall Manor on the Cayman Islands. Through their analysis, they discovered that the pottery was not locally pr.....»»
Saturday Citations: Teen seals photobomb research site; cell phones are safe; serotonin and emotional resilience
If you're not susceptible to urban myths and misinformation, there's a new study from the World Health Organization that will ease your 2010s-era anxieties about cell phones. There were a lot of other developments this week, including the return of B.....»»
