The cell sentinel that neutralizes hepatitis B
The hepatitis B virus (HBV) is responsible for one of the most serious and common infectious diseases. Transmitted through biological fluids, it attacks the liver cells. The chronic form of the disease can lead to serious complications, including cir.....»»
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.....»»
"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.....»»
Apple’s 13-inch M4 iPad Pro up to $200 off, Apple MagSafe iPhone 15 Clear Case 35% off, Siri smart home gear, more

Aging Might Not Be Inevitable
There are biological underpinnings to aging—and so researchers are investigating cell manipulations, transfusions of young blood, and chemical compounds that can mimic low-calorie diets......»»
Researchers capture never-before-seen view of gene transcription
Every living cell transcribes DNA into RNA. This process begins when an enzyme called RNA polymerase (RNAP) clamps onto DNA. Within a few hundred milliseconds, the DNA double helix unwinds to form a node known as the transcription bubble, so that one.....»»
Researchers uncover protein SRSF1"s uncommon ability to bind and unfold RNA G-quadruplexes
RNA transcription is the genomic process in which a cell produces a duplicate of a gene's DNA sequence. In a study published in Nucleic Acids Research, University of Alabama at Birmingham Department of Chemistry Professor Jun Zhang, Ph.D., and his te.....»»
Novel method for mass production of recombinant proteins uses mono-sodium glutamate
Mass production of recombinant proteins using yeast cell "factories" needs methanol, a compound that requires safe handling, carries the risk of catching fire, and sometimes produces harmful byproducts. Researchers at the Department of Biochemistry (.....»»
Understanding how zwitterionic polymers can lead to safer drugs and disease prevention
Proteins are vital biomolecules responsible for performing various functions in the human body and are thus regarded as the workhorses of a cell. The primary structure of a protein is composed of different amino acids coming together. The structure s.....»»
The Galaxy Z Flip 6 is getting a much-needed battery upgrade
Samsung may finally be trying to address one of the biggest problems with the Galaxy Z Flip 6 by putting a bigger dual cell battery into the foldable......»»
A change of direction: Research reveals a new method to manipulate cell movement in embryos
As embryos grow from conception to birth, cells multiply rapidly and move in a highly organized manner to create the skeleton, organs and other crucial systems. But how do cells know to move in precisely the right direction at the right time to creat.....»»
