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......»»
New methods for effective transport of large genes in gene therapy
One problem in gene therapy is that not all genes transfer equally well into the target cells. UZH researchers have now developed a flexible method to transfer large genes efficiently and without significant side effects. The approach has strong pote.....»»
Perovskite nanocrystalline cheaper than silicon for photovoltaic cells, study shows
New research from Brock University is introducing a highly efficient material for solar panels that is significantly less expensive than the silicon currently dominating the industry......»»
Apoptotic cells may drive cell death in hair follicles during regression cycle
A new research paper titled "Apoptotic cells may drive cell death in hair follicles during their regression cycle" has been published in Oncotarget......»»
Q&A: Developing a tool to identify cancerous cells from their membranes
Dr. Basudev Roy, Associate Professor in the Department of Physics at the Indian Institute of Technology, Madras, has recently published a paper about cell membrane fluctuations and their use for diagnosing cancerous diseases in the journal Physical B.....»»
Wobbly gel mat trains muscle cells to work together
There's no doubt that exercise does a body good, including strengthening and toning our muscles. But how exactly does exercise make this happen?.....»»
Researchers develop novel data representation for transcription factor-binding sequences
The diverse characteristics of the human body's various cells are reflected in their gene expression patterns. The regulation of such gene expression is based on transcription factors that bind to specific sequences in the genome......»»
Miniature magnetic resonance imager made of diamond
The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now, the resolution of conventional imaging methods has not been high enough to r.....»»
Restoring the function of a human cell surface protein in yeast cells
G protein-coupled receptors (GPCRs) are the largest and most diverse group of cell surface proteins in humans. These receptors, which can be seen as "traffic directors," transmit signals from the outside to the inside of cells and are involved in man.....»»
Researchers develop an innovative microscope platform to unveil the intricacies of skeletal muscle regeneration
Researchers at the Hong Kong University of Science and Technology (HKUST) have created a cutting-edge platform consisting of a dual-laser nonlinear optical microscope to investigate the dynamics of muscle satellite cells (MuSCs) during the process of.....»»
Using AI to develop hydrogen fuel cell catalysts more efficiently and economically
Proton exchange membrane hydrogen fuel cells (PEMFCs) used in hydrogen vehicles use expensive platinum catalysts to facilitate the oxygen reduction reaction at the anode. There are a vast number of elemental combinations and compositions that need to.....»»
Agronomists protect plants from heavy metals with hormone therapy and the mineral zeolite
RUDN University agronomists have shown that the hormone melatonin and the mineral zeolite mitigate the dangerous effects of heavy metals on plants. The first protects cells from destruction by cadmium, and the second increases nutrient availability a.....»»
Pathogen that plagues food processing plants eradicated by blue light
Blue light kills both dried cells and biofilms of the pathogen Listeria monocytogenes, a frequent contaminant of food processing facilities. Demise of L. monocytogenes occurred quickest when cells or biofilms were placed on polystyrene, a widely used.....»»
Targeting a coronavirus ion channel could yield new COVID-19 drugs
The genome of the SARS-CoV-2 virus encodes 29 proteins, one of which is an ion channel called E. This channel, which transports protons and calcium ions, induces infected cells to launch an inflammatory response that damages tissues and contributes t.....»»
Deep self-learning enables volumetric microscopy with 3D isotropic resolution
Volumetric fluorescence microscopy is an indispensable tool for comprehensive studies of cells and organs. Since the specimens are inherently three-dimensional (3D), the optimal imaging system should possess high spatial resolution in all directions......»»
Biologists find salicylic acid and RNA interference mediate antiviral immunity of plant stem cells
Viruses are a threat to all organisms, including plants. A small group of plant stem cells, however, successfully defends itself from infection......»»
Ultium Cells EV battery plant in Ohio faces $270,000 in OSHA fines
The U.S. Department of Labor's Occupational Safety and Health Administration said investigators examining the cause of a March 2023 explosion and fire at the plant led the agency to cite the company for 17 serious violations and two other violations.....»»
Solar Storms Can Hinder Bird Migration
New research suggests that solar storms interfere with the magnetic compass that birds use for long-distance travel.....»»
Cover crops found to reduce carbon loss in the soil of Mediterranean olive groves by more than 75%
Agricultural soils sustain life by producing food, but they also play an essential role in climate change, functioning as carbon sinks, storing large quantities of carbon and reducing its concentration in the atmosphere. Carbon is the main indicator.....»»
New method to predict the risk of adverse drug events
Studying signaling within cells can predict the risk of adverse drug reactions of novel obesity and type II diabetes treatments before they reach the patient, according to a new study from Karolinska Institutet published in Nature Communications......»»
Metal-free and transition-metal-doped ZIF-8@CNT catalysts prepared by one-step high-temperature pyrolysis
