Proteins let cells remember how well their last division went
Scientists find a "mitotic stopwatch" that lets individual cells remember something. Enlarge (credit: Martin Barraud) When we talk about memories in biology, we tend to focus on the brain and the storage of information i.....»»
New tool to map protease specificity may pave the way for improved treatments
FMI researchers have developed a new tool that maps how proteases—enzymes that process proteins—cut their targets. This innovation offers new insight into the highly selective nature of proteases, which were previously seen as indiscriminate degr.....»»
Human Cell Atlas achieves leap in the understanding of the human body
Researchers with the global Human Cell Atlas (HCA) consortium report significant progress in their quest for a better understanding of the cells of the human body in health and disease, with the publication on 20 November of a collection of more than.....»»
Self-assembling proteins can be used for higher performance, more sustainable skincare products
If you have a meticulous skincare routine, you know that personal skincare products (PSCPs) are a big business. The PSCP industry will reach $74.12 billion USD by 2027, with an annual growth rate of 8.64%. With such competition, companies are always.....»»
Nanofibers made of copper-binding peptides disrupt cancer cells
While toxic in high concentrations, copper is essential to life as a trace element. Many tumors require significantly more copper than healthy cells for growth—a possible new point of attack for cancer treatment......»»
Can going to a haunted house boost the immune system?
Study found marked decrease in inflammatory markers and white blood cells after visiting a haunted house. Spooky season has come and gone, but those Halloween revelers who took in.....»»
By exerting "crowd control" over mouse cells, scientists make progress towards engineering tissues
Genes aren't the sole driver instructing cells to build multicellular structures, tissues, and organs. In a paper published in Nature Communications, USC Stem Cell scientist Leonardo Morsut and Caltech computational biologist Matt Thomson characteriz.....»»
Machine learning and supercomputer simulations predict interactions between gold nanoparticles and blood proteins
Researchers in the Nanoscience Center at the University of Jyväskylä, Finland, have used machine learning and supercomputer simulations to investigate how tiny gold nanoparticles bind to blood proteins. The studies discovered that favorable nanopar.....»»
Samsung is developing Gemini AI-powered XR glasses, and we might’ve already seen them
Remember when Samsung invited Google and Qualcomm to announce the “next XR experience“? I know I do because it happened in early February 2023, during … The post Samsung is developing Gemini AI-powered XR glasses, and we might’.....»»
Researchers characterize regulating mechanism of orderly zygotic genome activation in early embryos
Early development of an embryo is solely supported by maternally deposited RNAs and proteins until its own genome is activated through a process called zygotic genome activation (ZGA). Recent work by Chinese scientists has revealed a novel molecular.....»»
Human brain organelles study shows dopamine neurons must work a lot harder than those in primate relatives
A team of neurologists, bioengineers and radiologists has found that two neurons in the human brain that code for dopamine production have to work harder than similar cells in primate relatives. The group has posted a paper describing their work on t.....»»
Viscosity of materials key to cell differentiation: New insights could improve design of biomaterials
An IBEC-led study has revealed how mesenchymal stem cells respond to the viscosity of their environment, a key aspect in their differentiation process......»»
How marine worms regenerate lost body parts: Return of cells to stem cell-like state could be key
Many living organisms are able to regenerate damaged or lost tissue, but why some are particularly good at this and others are not is not fully understood. Molecular biologists Alexander Stockinger, Leonie Adelmann and Florian Raible from the Max Per.....»»
Selenoproteins open new strategies for treating certain cancers in children
Selenoproteins are crucial for several biological functions, including the breakdown of harmful substances, immune system support, and regulating metabolic processes. However, in specific contexts, these proteins can be misused and shield cancer cell.....»»
Genes of ancient animal relatives used to grow a mouse: Study reveals hidden history of stem cells
An international team of researchers has achieved an unprecedented milestone: the creation of mouse stem cells capable of generating a fully developed mouse using genetic tools from a unicellular organism, with which we share a common ancestor that p.....»»
Study uncovers role of tissue viscoelasticity in cell response
To the casual eye, a memory foam mattress would appear to have no relationship to the behavior of cells and tissues. But an innovative study carried out at the Centro de Investigaciones Cardiovasculares (CNIC) in Madrid shows that viscoelasticity—t.....»»
Age on the molecular level: Research analyzes quantitative changes in a wide range of proteins
With the worldwide population aging at an unprecedented rate, the prevention of age-related diseases has become a prominent issue. It is important to comprehensively and quantitatively evaluate the changes that aging causes at the molecular level in.....»»
Using genetic code expansion to study membrane proteins
Over the years, chemical biology methods have made an important contribution to the study of integral membrane proteins. A key modern approach is genetic code expansion (GCE), which makes it possible to modify proteins directly in living cells to giv.....»»
Picky proteins: Understanding yeast adaptor protein selectivity
The cellular membrane controls the passage of substances in and out of the cell. Some larger cargo, such as membrane proteins, nutrients, and pathogens, enter the cell via a process known as clathrin-mediated endocytosis......»»
Bone Marrow Donors Can Be Hard to Find. One Company Is Turning to Cadavers
