Droplets in cells found to determine the accumulation of proteins in age-related diseases
Tiny droplets in cells can accelerate the accumulation of protein deposits in diseases such as Alzheimer's and Parkinson's disease, but they can also hinder this accumulation. While they will worsen the accumulation if the proteins stick to the edge.....»»
Researchers uncover key insights into cholesterol"s structure in cell membranes
A new study by Rice University researchers led by Jason Hafner could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. Th.....»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
From chaos to order: Proteins can re-structure themselves to create important substances
The protein "MIPS" changes its internal structure when it becomes active. Its disordered active center becomes a defined structure with special functions. The protein plays a key role in the production of inositol, which is also known as vitamin B8,.....»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
Giant panda skin cells transformed into stem cells to help ensure their survival
A team of biologists in China has reprogrammed skin cells from giant pandas into induced pluripotent stem cells (iPSCs), opening the door to creating primordial germ cells that could serve as precursors to sperm and egg cells......»»
Scientists reviewed 7,000 studies on microplastics. Their alarming conclusion puts humanity on notice
It's been 20 years since a paper in the journal Science showed the environmental accumulation of tiny plastic fragments and fibers. It named the particles "microplastics.".....»»
New method developed to relocate misplaced proteins in cells
Cells are highly controlled spaces that rely on every protein being in the right place. Many diseases, including cancers and neurodegenerative disorders, are associated with misplaced proteins. In some cancers, for instance, a protein that normally s.....»»
New data science tool greatly speeds up molecular analysis of our environment
A research team led by scientists at the University of California, Riverside, has developed a computational workflow for analyzing large data sets in the field of metabolomics, the study of small molecules found within cells, biofluids, tissues, and.....»»
Researchers identify novel endocytic recycling mechanism with "kiss-and-run" membrane fusion
Endocytosis and recycling control the uptake and retrieval of various materials in eukaryotic cells. Mammalian cells have developed several recycling routes, including the relatively extensively studied "fast" and "slow" tubulovesicular recycling pat.....»»
Study shows cholesterol enhances exosome-mediated RNA drug delivery
RNA interference (RNAi) technology has gradually become a cutting-edge technology for treating diseases such as genetic disorders and cancer due to its huge potential in gene expression regulation. However, the efficient delivery and safety of short.....»»
Female elephants rumble to say "let"s go!" Namibian study shows males do too, a sign of unexpected social bonds
In elephant family groups made up of related females and their young, it is clear that the animals produce vocal sounds to coordinate action. This happens when it's time to leave a waterhole, for example. The matriarch or dominant female steps away f.....»»
Exploring the interplay between phosphate signaling and jasmonate pathways in tea plants
Catechins, the key active components in tea, are known for their protective effects against conditions like diabetes, cancer, and cardiovascular diseases. However, their biosynthesis is highly sensitive to environmental factors, particularly phosphat.....»»
Cooler heads prevail: New research reveals best way to prevent dogs from overheating
As temperatures continue to soar across the country, a simple yet innovative technique could be the key to keeping dogs safe from heat-related illnesses......»»
Creator of fake Kamala Harris video Musk boosted sues Calif. over deepfake laws
Online influencer "Mr Reagan" accuses California of bullying humorists. Enlarge (credit: NurPhoto / Contributor | NurPhoto) After California passed laws cracking down on AI-generated deepfakes of election-related content.....»»
How plants keep viruses from passing to their progeny
Scientists have learned how plants keep viruses from being passed to their offspring, a finding that could ensure healthier crops. The discovery could also help reduce the transmission of diseases from mothers to human children......»»
First-of-its kind tool allows scientists to manipulate cells without touching them
When studying the spread of cancer or the behavior of a virus like the one that causes COVID-19, the irony is that working with these harmful pathogens requires gentleness. Especially in the case of COVID, the particles do not survive well when makin.....»»
Light-induced immunoassay can selectively detect coronavirus spike proteins in five minutes
Like moths to a flame, microbes can also be moved by light. Using this knowledge, researchers from Osaka Metropolitan University's Research Institute for Light-induced Acceleration System (RILACS) have demonstrated a method to detect the presence of.....»»
Arctic warming may fuel ice formation in clouds, observations suggest
The Arctic frequently experiences temperatures that support the formation of mixed-phase clouds that contain supercooled liquid droplets and ice crystals. The composition of such clouds plays a crucial role in the region's energy balance and climate.....»»
New testing system uses Janus particles to rapidly and accurately detect COVID-19
The importance of testing for diseases was thrust into the limelight during the COVID-19 pandemic. Many of us have undergone a PCR (Polymerase Chain Reaction) or ELISA (Enzyme-Linked Immunosorbent Assay) test within the past four years......»»
