Researchers at have solved a longstanding puzzle concerning the design of molecular motors, paving the way toward new cancer therapies.
Researchers at Osaka University used live imaging of the Drosophila embryonic hindgut and computer simulations to clarify that a novel cellular behavior called 'cell sliding' was important for the LR asymmetric morphogenesis of the organ.
When applied to cells, pulsed electric fields increase membrane permeability. Researchers have used this effect to force the diffusion of extracellular calcium into cells. Cell death occurs more easily in cancer cells since they are particularly sensitive to high amounts of calcium. Researchers from Kumamoto University in Japan have optimized pulsed electric field settings in an effort to attack cancer but leave healthy cells intact.
A new study sheds light on the mystery of how evolution tweaks the brain to shape behavior. It started with a close look at two Drosophila species and their mating maneuvers.
Researchers from the University of Utah have discovered why certain people experience dizziness when they hear a particular sound, such as a musical tone. For patients with semicircular canal dehiscence, there is a pathological hole in the bone that the inner ear is encased in, and certain acoustic tones cause the inner ear fluid to pump. As a result, the ear sends an incorrect signal to the brain, causing dizziness and vertigo.
Recent research led by Professor G.V. Shivashankar of the Mechanobiology Institute at the National University of Singapore and the FIRC Institute of Molecular Oncology in Italy, has revealed that mature cells can be reprogrammed into re-deployable stem cells without direct genetic modification -- by confining them to a defined geometric space for an extended period of time.
Nanofiber-based wound dressings loaded with vitamin D spur the production of an antimicrobial peptide, a key step forward in the battle against surgical site infections, or SSIs.
Most people have never heard of them, and yet every living being needs them to survive: fine protrusions of cells known as cilia. They allow sperm to move, form fine protective hairs in the lungs and play a crucial role in the differentiation of organs in embryos. A research team at the Technical University of Munich has now reconstructed the protein complex responsible for transport within cilia, which plays a decisive role in their functioning.
The aerodynamic capabilities of spiders have intrigued scientists for hundreds of years. Charles Darwin himself mused over how hundreds of the creatures managed to alight on the Beagle on a calm day out at sea and later take-off from the ship with great speeds on windless day.
Locking DNA knots in place thanks to DNA propensity to be supercoiled. A new study by SISSA suggests that is one of the mechanisms that could be harnessed by the cellular machinery to deal with those accidental entanglements that can compromise DNA functionality.
