Cells use concentration gradients as a compass
Biophysicists at Ludwig-Maximilians-Universitaet (LMU) in Munch have developed a new theory, which accounts for the observation that cells can perceive their own shapes, and use this information to direct the distribution of proteins inside the cell......»»
Tesla scrambles to boost Cyrbertruck battery output
Tesla's Giga Texas factory is churning out 4680 battery cells at a rate only sufficient to power about 24,000 Cybertrucks a year, or about a 10th of the required output, Reuters found......»»
Unimolecular self-assembled hemicyanine-oleic acid conjugate acts to eliminate cancer stem cells: Study
Cancer stem cells (CSCs) are a rare population of cells in tumor tissues that drive tumorigenesis, recurrence, and metastasis. Therefore, the development of anti-tumor therapies that can eliminate CSCs has significant implications for cancer treatmen.....»»
The evolutionary timeline of diminished boric acid and urea transportation in aquaporin 10
Aquaporin (Aqp) 10 water channels in humans allow the free passage of water, glycerol, urea, and boric acid across cells. However, Aqp10.2b in pufferfish allows only the passage of water and glycerol and not urea and boric acid......»»
Sustainable, more efficient synthesis route of hyaluronic acid polymers for biomedical applications
Hydrogels—polymer networks with high water content—can act as a tissue mimic, providing conditions for a viable culture of embedded cells, with various applications in biomedical engineering such as tissue engineering and regenerative medicine......»»
Human brain cells put much more energy into signaling
Signaling molecules help modulate the brain's overall activity. Enlarge (credit: Westend61) Indian elephants have larger brains than we do (obviously). Mice have a higher brain-to-body mass ratio, and long-finned pilot w.....»»
Researchers discover crucial step in creating blood stem cells
A microbial sensor that helps identify and fight bacterial infections also plays a key role in the development of blood stem cells, providing a valuable new insight in the effort to create patient-derived blood stem cells that could eliminate the nee.....»»
"Molecular jackhammers" can rupture melanoma cells" membrane, study shows
The Beach Boys' iconic hit single "Good Vibrations" takes on a whole new layer of meaning thanks to a recent discovery by Rice University scientists and collaborators, who have uncovered a way to destroy cancer cells by using the ability of some mole.....»»
Canada"s agricultural policies need to better serve local farmers and communities, says researcher
Canada's current agricultural production model is unsustainable and in desperate need of reform. A range of issues plague the current system, including corporate consolidation, farmland concentration in the hands of non-farmers and foreign buyers, po.....»»
Harnessing nanotechnology to understand tumor behavior
A new study conducted by pre-Ph.D. researcher Pablo S. Valera demonstrates the potential of surface-enhanced Raman spectroscopy (SERS) to explore metabolites secreted by cancer cells in cancer research......»»
Eggs from men, sperm from women: How stem cell science may change how we reproduce
It may soon be possible to coax human skin cells into becoming functional eggs and sperm using a technique known as "in vitro gametogenesis." This involves the creation (genesis) of eggs and sperm (gametes) outside the human body (in vitro)......»»
If you love Dead Cells, you need to try this sci-fi roguelike next
Trinity Fusion is a sci-fi roguelike that fans of Dead Cells (and Metroid) will want to check out......»»
New method tags cells with location coordinates for single-cell studies
When a scientist wants to study individual cells at the molecular level within an organ like the heart or brain, they usually break the tissue up to analyze the cells. This provides rich detail about gene activity, but doesn't retain information abou.....»»
Ukrainian cells and Internet still out, 1 day after suspected Russian cyberattack
Hackers tied to Russian military take responsibility for hack on Ukraine's biggest provider. Enlarge / A service center for "Kyivstar", a Ukrainian telecommunications company, that provides communication services and data transmi.....»»
New embryo-like model simulates early human blood production
University of Pittsburgh researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells......»»
Cells found to move differently in groups than they do when alone
A protein that helps generate the force needed for single cells to move works differently in cells moving in groups, a new study shows......»»
GM partners with Komatsu on hydrogen fuel cells for mining vehicles
The first prototype built with technology from GM's Hydrotec hydrogen fuel cell unit will be tested mid-decade at a Komatsu R&D facility in Arizona, the companies said......»»
Could the "central dogma" of biology be misleading bioengineers?
Today, medicines based on antibodies—proteins that fight infection and disease—are prescribed for everything from cancer to COVID-19 to high cholesterol. The antibody drugs are supplied by genetically-engineered cells that function as tiny protei.....»»
Migratory bats can detect the Earth"s magnetic field, behavioral experiments show
Pipistrelle bats have a magnetic compass and calibrate it at sunset, according to a new study. An international team of researchers led by the University of Oldenburg has used behavioral experiments to show that two different components of the Earth'.....»»
Study analyzes how the green transition affects competition and concentration in the business market
The green transition towards a more sustainable and environmentally friendly economy has become a necessity to combat climate change, the scarcity of resources, and pollution. Businesses have been forced to shift from traditional fossil fuels to rene.....»»
New technique to analyze RNA-RNA interactions in live microbial cells
