The bald truth: Altered cell divisions cause hair thinning
Researchers have identified a novel mechanism underlying hair thinning and loss during aging. By studying cell division of hair follicle stem cells in young and aged mice, the researchers found that young mice properly balance typical symmetric and a.....»»
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.....»»

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.....»»
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.....»»
Detecting defects in tomorrow"s technology: Study enhances understanding of likely candidate for next-generation chips
Silicon computer chips have served us well for more than half a century. The tiniest features on chips currently sold are approximately 3 nanometers—a startlingly small size given that a human hair is roughly 80,000 nanometers wide. Reducing the si.....»»
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.....»»
"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......»»
A closer look at cell toxins: Researchers examine how radionuclides interact with kidney cells
When radionuclides enter our organism, whether by inhalation, ingestion, or through wounds, they pose a potential health risk. Many previous studies on radionuclide exposure have focused mainly on animal experiments. However, we have little data on t.....»»
Researchers uncover key mechanisms in chromosome structure development
Researchers at Rice University are making strides in understanding how chromosome structures change throughout the cell's life cycle. Their study on motorized processes that actively influence the organization of chromosomes appears in the Proceeding.....»»
Image: Orion spacecraft prepares for upcoming launch
Technicians lift NASA's Orion spacecraft out of the Final Assembly and System Testing cell on June 28, 2024. The integrated spacecraft, which will be used for the Artemis II mission to orbit the moon, has been undergoing final rounds of testing and a.....»»
