Simulating the shear destruction of red blood cells
Many medical devices for treating heart failure generate nonphysiological shear flow. This can trigger the destruction of red blood cells after implantation of ventricular assist devices (VADs), artificial heart valves, vascular stents, or interventi.....»»
Why not knowing what to do isn"t always a bad thing for leaders
In 2002, after a Pentagon news briefing, the then US secretary of defense Donald Rumsfeld was widely ridiculed for his thoughts about knowledge. Discussing the issue of whether Iraq was supplying weapons of mass destruction to terrorists, he said, "A.....»»
New cobalt complex triggers ferroptosis in cancer cells
In programmed cell death, certain signaling molecules initiate a kind of suicide program to cause cells to die in a controlled manner. This is an essential step to eliminate damaged cells or to control the number of cells in certain tissues, for exam.....»»
An affordable tracking microscope to democratize microorganism research
Studying the complex motility patterns of cells and microorganisms is key to understanding their behaviors and biomechanics. However, many conventional microscopes are constrained by fixed lenses and the lack of ability to track organisms over extend.....»»
Common equine painkiller disrupts assisted reproduction technique efficiency in mares
Researchers at the Texas A&M School of Veterinary Medicine & Biomedical Sciences (VMBS) have discovered that phenylbutazone, a non-steroidal anti-inflammatory drug (NSAID) commonly prescribed in horses, can affect the ability of a mare's egg cells—.....»»
Advance in stem cell therapy: New technique for manipulating stem cells opens door to novel treatments
A new technique developed by McGill researchers for mechanically manipulating stem cells could lead to new stem cell treatments, which have yet to fulfill their therapeutic potential......»»
AI-driven method enhances electron microscopy imaging capabilities of complex biological systems
Electron microscopy has enabled visualization of the intricate details inside cells. The advancement to 3D electron microscopy, known as volume EM (vEM), has further expanded this three-dimensional, nanoscale imaging capacity. However, trade-offs bet.....»»
Starvation and adhesion drive formation of keratinocyte patterns in skin, research reveals
Fingerprints are one of the best-recognized examples of pattern formation by epithelial cells. The primary cells in the epithelium are the keratinocytes, and they are known to form patterns at the microscopic and macroscopic levels. While factors aff.....»»
International team discovers key protein that helps cells maintain their identity
A discovery regarding Mrc1 (Mediator of Replication Checkpoint 1)—a fission yeast protein involved in DNA replication—has been published in Cell. The discovery is the result of an international research collaboration, led by Professors Genevieve.....»»
A new robotic platform to reproduce and study complex ciliary behavior
Cilia are sensory structures extending from the surface of some cells. These hair-like structures are known to contribute to the sensorimotor capabilities of various living organisms, including humans......»»
NASA tests deployment of Roman Space Telescope"s "visor"
The "visor" for NASA's Nancy Grace Roman Space Telescope recently completed several environmental tests simulating the conditions it will experience during launch and in space. Called the Deployable Aperture Cover, this large sunshade is designed to.....»»
Heat stress survival: Unraveling the HsfA2-ACTIN dynamics in lily varieties
A research team has identified that the heat stress transcription factor HsfA2 and actin-interacting protein (AIP) LACTIN interact at the protein level in Lilium longiflorum "White Heaven," mediating gene expression and protecting cells from heat str.....»»
Microscopy technique "paves way" for improving understanding of cellular functions
Scientists have developed a new way of counting labeled proteins in living cells that could become a standard and valuable tool in the field of biomedical research......»»

Study reveals how plants decide between life and death
Researchers at Michigan State University have discovered two proteins that work together to determine the fate of cells in plants facing certain stresses......»»
3D-printed blood vessels bring artificial organs closer to reality
Growing functional human organs outside the body is a long-sought "holy grail" of organ transplantation medicine that remains elusive. New research from Harvard's Wyss Institute for Biologically Inspired Engineering and John A. Paulson School of Engi.....»»
Scientists use carbon isotopes to track "forever chemicals"
Organofluorine compounds—sometimes called "forever chemicals"—are increasingly turning up in our drinking water, oceans and even human blood, posing a potential threat to the environment and human health......»»
How ribosomes in our cells enable protein folding
Scientists at UCL have discovered a novel role played by ribosomes during the folding of new proteins in cells, described in their paper in Nature......»»
She’s the New Face of Climate Activism—and She’s Carrying a Pickax
Sabotage. Property destruction. For Léna Lazare and her cohort, radicalized by years of inaction on the environmental crisis, these aren’t dirty words. They’re acts of joy......»»
Coupling excitons to polaritons for better solar cells and higher intensity LEDs
In solar cells and light-emitting diodes, maintaining the excited state kinetics of molecules against annihilation is a race against time. These systems need to strike a careful balance between different processes that lead to loss of energy and thos.....»»
