Uncovering the link between cell biomechanics and wound healing
An interdisciplinary team of researchers from the Indian Institute of Science (IISc) has uncovered how the stiffness of a cell's microenvironment influences its form and function. The team was led by Namrata Gundiah, Professor at the Department of Me.....»»
Advanced imaging reveals how a parasitic "kiss" alters cell metabolism
Toxoplasma gondii is a parasite responsible for toxoplasmosis, a lifelong chronic infection prevalent in about 30% of the human population. It poses little harm to healthy individuals, but can result in severe consequences for immunocompromised peopl.....»»
Team develops the first cell-free system in which genetic information and metabolism work together
The capacity of all living systems to develop, organize and sustain themselves is based upon a cyclical process in which genes and metabolism interact in parallel. While genes encode the components of metabolism, metabolism provides the energy and bu.....»»
Apple is trying to reinvent group audio chat with no cell or WiFi needed
Apple is developing technology that would allow any number of willing people in close proximity to start an audio chat, using only an iPhone and a headset like AirPods, with no WiFi or cell service needed.Using an iPhone and a headset, many people co.....»»
Team investigates chemical modifications to gain deeper insights into genetic regulation mechanisms
University of North Carolina at Chapel Hill researchers have determined whether a specific chemical modification of a protein that packages the genome called a histone affects gene activity and cell proliferation, according to the paper, "Drosophila.....»»
A Retracted Stem Cell Study Reveals Science’s Shortcomings
The withdrawal after 22 years of a controversial stem cell paper highlights how perverse incentives can distort scientific progress.....»»

While July 4th has come and gone for another year, there are still loads of price drops live to take advantage of in our roundup right here. And we are now tracking new deals we spotted this morning including $160 off the 1TB 13-inch M4 iPad Pro Wi-F.....»»
Researchers discover a new form of scientific fraud: Uncovering "sneaked references"
A researcher working alone—apart from the world and the rest of the wider scientific community—is a classic yet misguided image. Research is, in reality, built on continuous exchange within the scientific community: First you understand the work.....»»
Phage-derived enzyme targets E. faecalis biofilms to mitigate acute graft-versus-host disease
Allogenic hematopoietic cell transplantation (allo-HCT) involves transferring healthy donor stem cells to recipients with conditions such as blood cancer, bone marrow failure, or certain genetic blood disorders. Acute graft-versus-host disease (aGVHD.....»»
Astronomers find the nearest massive black hole, a missing link in massive black hole formation
Newly identified fast-moving stars in the star cluster Omega Centauri provide solid evidence for a central black hole in the cluster. With at least 8,200 solar masses, it is the best candidate for a class of black holes astronomers have long believed.....»»
Team discovers a new defense mechanism in bacteria
When confronted with an antibiotic, toxic substance, or other source of considerable stress, bacteria are able to activate a defense mechanism using cell-to-cell communication to "warn" unaffected bacteria, which can then anticipate, shield themselve.....»»
Dealers in Texas grapple with power outages, poor cell service after Beryl
Some dealers have reopened following damages, while others struggle to become functional again......»»
Team develops new one-step method to make multiple edits to a cell"s genome
Genome editing has become a widely adopted technology to modify DNA in cells, allowing scientists to study diseases in the lab and develop therapies that repair disease-causing mutations. However, with current approaches, it's only possible to edit c.....»»
Newly identified enzyme helps pathogenic fungus build protective cell wall
Researchers at the School of Medicine have identified a novel enzyme involved in building the cell wall of Cryptococcus neoformans, a fungus that causes lung infections and potentially deadly cases of meningitis, primarily in people with AIDS. About.....»»
Egg cell maintenance: Long-lived proteins may be essential for fertility
Female mammals—including humans—are born with all of their egg cells. Of a woman's one to two million egg cells, about 400 mature before menopause and can be fertilized. Some egg cells therefore survive for several decades—and need to remain fu.....»»
First set of rational design principles for chaotropic membrane transporters
The challenge of internalizing impermeable molecules into cells persists in drug development, particularly concerning water-soluble bioactive compounds that cannot diffuse across the cell membrane. To overcome this problem, various artificial transpo.....»»
Novel time-of-flight-resolved stimulated Raman scattering microscopy enables high-resolution bioimaging
Stimulated Raman scattering (SRS) microscopy is an optical vibrational spectroscopic imaging technique and has emerged as an appealing label-free imaging tool for tissue and cell imaging and characterization with high biochemical specificity......»»
Study reveals how stress pathways activate a cell"s emergency response procedures
Mayday! SOS! Distress signals like these are used around the world to indicate an emergency. The cells that make up your body also have their own versions of emergency signals. These get activated if a cell is infected by a virus or bacteria, or if t.....»»
This new technology fixes the biggest problem with modern GPUs
Using their optimized Compute Express Link or CXL, Panmnesia is working on a solution to expand memory capacity for GPUs and AI accelerators......»»
High speed video shows hippos get airborne when running
A pair of evolutionary biomechanics specialists at the University of London's, Royal Veterinary College, has found that when hippos run at full speed, all four of their feet are regularly in the air......»»
"Vaults" within germ cells offer more than safekeeping
Maternal messenger RNAs (mRNAs), located within the cytoplasm of an immature egg, are crucial for jump starting development. Following fertilization, these mRNAs are passed onto the zygote, the first newly formed cell......»»
