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......»»
Two keys needed to crack three locks for better engineered blood vessels
Blood vessels engineered from stem cells could help solve several research and clinical problems, from potentially providing a more comprehensive platform to screen if drug candidates can cross from the blood stream into the brain to developing lab-g.....»»
How cells in plant leaves organize themselves to ensure optimal area for photosynthesis

Development of novel aptamers unlocks opportunities for the treatment of cancers and neurological diseases
G-quadruplexes (G4), which are special structures in DNA and RNA that play a crucial role in cells, have been associated with cancers and neurological diseases. A research team from City University of Hong Kong (CityU) recently built a new platform t.....»»
Did the first cells evolve in soda lakes?
Soda lakes, which are dominated by dissolved sodium and carbonate species, could have provided the right conditions for the first cells, according to a new study published in PNAS Nexus......»»
The Honda CR-V e:FCEV is a plug-in fuel-cell hybrid nobody asked for
Hydrogen has problems, and this isn't a solution, but it's a decent CR-V. Enlarge / We still think hydrogen fuel cells make more sense for static generators like the ones in the background, but Honda decided to make a fuel cell-p.....»»
How DHX9 stress granules protect daughter cells from UV-induced RNA damage
During the process of cell division, new daughter cells inherit a mix of genetic material and other molecules from their mother cells. This inheritance includes both beneficial components, which can help them for a robust start in life, and potential.....»»
Scientists publish novel research on how individual cells respond to viral infection
A team of scientists from Montana State University recently published unique research examining how individual cells respond to viral infection. The work used state-of-the-art technology to culture cells and track infection in real time; it is the fi.....»»
Study shows how surface curvature drives cell migration
The curvature of a surface determines the migration behavior of biological cells. They preferentially move along valleys or grooves while avoiding ridges. These findings, published in the journal Proceedings of the National Academy of Sciences with c.....»»
Using a non-destructive, light diffraction fingerprint technique to detect viral infections in cells
A combined team of engineers from Jiangsu University and Harvard University used a non-destructive, light diffraction fingerprint technique to detect viral infections in cells. Their paper is published in the journal Science Advances......»»
In vivo production of CAR-T cells using virus-mimetic fusogenic nanovesicles
Chimeric antigen receptors (CARs) are synthesized membrane proteins that enable lymphocytes to recognize and respond to the specific antigens of target cells. Despite the impressive efficacy of CAR-T cell therapy in treating B-cell lymphoma or leukem.....»»
Researchers find new ways to regulate hole transport layer for efficient perovskite solar cells
According to a study published in Nano Energy, a research group led by Prof. Chen Chong from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has increased the photoelectric conversion efficiency (PCE) of perovskite solar c.....»»
Research uncovers specific protein interactions needed for cells to break down and remove damaged mitochondria
Autophagy is a process used by cells as a recycling system to transport and break down organelles and other cytosolic components, which become enveloped in a membrane called the autophagosome. When this involves the removal of damaged mitochondria, i.....»»
Supercharging fuel cells with caffeine
With global goals set on transitioning away from fossil fuels, fuel cells stand out as a promising carbon-free energy source. Comprising an anode and a cathode separated by an electrolyte, fuel cells convert the chemical energy of fuel directly into.....»»
Study shows for the first time that different forms of cellular adhesion structures can interconvert
Cells form adhesion structures to anchor themselves in their environment. The coordinated assembly and disassembly of these adhesions also enables cells to move from one place to another......»»
Why eukaryotes, not bacteria, evolved complex multicellularity
Prokaryotic single-celled organisms, the ancestors of modern-day bacteria and archaea, are the most ancient form of life on our planet, first appearing roughly 3.5 billion years ago. The first eukaryotic cells appeared around 1–1.5 billion years la.....»»
A novel strategy to efficiently distinguish subtype-specific cardiomyocytes from human iPS cells
In a recent study led by Associate Professor Yoshinori Yoshida (Department of Cell Growth and Differentiation) and published in Communications Biology, a team of researchers identified CD151 as a marker for distinguishing subtype-specific cardiomyocy.....»»
Automated high-throughput sorting of living cells using laser light and AI
Tests on living cell cultures are becoming increasingly important for personalized medicine, drug development and clinical research. The Aachen-based Fraunhofer Institutes for Laser Technology ILT and for Production Technology IPT have developed an A.....»»
Calls for reform to manage potential risks of modern slavery in the UK"s hospitality industry
The UK's tourism and hospitality industries, having a high concentration of migrant workers, face complex challenges in managing the risks of labor exploitation and modern slavery—according to a study from the University of Surrey......»»
Team makes progress with fluorescent dyes to better visualize lipid membrane order in live cells
