Filament structure found to activate and regulate CRISPR-Cas "protein scissors"
CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, al.....»»
Discovery of a tRNA modification enzyme that also acts on nucleosides
The genetic information on DNA is transcribed into messenger RNA (mRNA) and translated to the amino acid sequence by transfer RNA (tRNA) on the ribosome. Modified nucleosides within RNA are involved in maintaining and regulating the protein synthesis.....»»
Ground conditions can impact lunar swirls, study finds
Differences between the bright and dark patches in lunar swirls goes beyond the albedo variations; it includes differences in the structure of the lunar soils and the grains within those soils......»»
Dynamic view of opioid receptor could refine pain relief
Effective pain relief without the debilitating side effects of traditional opioids is closer to becoming a reality thanks to a study by an all-RIKEN team into the structure and dynamics of a drug-bound opioid receptor......»»
Ginseng"s full genome sequenced
Ginseng's role in traditional medicine is underscored by its complex genetic structure due to its allotetraploid nature. A recent study delves into this complexity, revealing key evolutionary insights into its subgenomes that govern saponin biosynthe.....»»
Study identifies RNA molecule that regulates cellular aging
A team led by UT Southwestern Medical Center researchers has discovered a new way that cells regulate senescence, an irreversible end to cell division. The findings, published in Cell, could one day lead to new interventions for a variety of conditio.....»»
Modular design: New insights into protein factories in human mitochondria
The "power plants" of living cells, the mitochondria, probably evolved through endosymbiosis: A bacterium migrated into a primordial cell and eventually developed into an organelle that provides the cell with energy, among other things. Mitochondria.....»»
Freezing and melting reshape diversity and structure of glacier microbial communities
With the increasing attention on global climate change and glacier retreat, the study of glacier microbiota has gradually become an important field of research......»»
Snakes on a plate: Pythons touted as protein alternative
In a warehouse in the lush humid farmlands of central Thailand, thousands of pythons lie coiled in containers, rearing and striking at the glass as people pass by......»»
Lab develops smallest free-floating bubbles for medical imaging
Bioengineering researchers at Rice University have developed ultrasmall, stable gas-filled protein nanostructures that could revolutionize ultrasound imaging and drug delivery......»»
How to insert a text box in Google Docs
Whether you want to make text stand out, add some structure, or create a unique visual, we’ll show you a few ways to insert a text box in Google Docs......»»
Research team develops light-activated compounds to treat neuropathic pain
Light can be used to activate drugs in specific parts of the body through photopharmacology. This innovative approach involves modifying the chemical structure of a drug by adding a light-activated molecular switch, such as azobenzene. This allows th.....»»
Scientists create computer program that "paints" the structure of molecules in the style of famous Dutch artist
Scientists from Trinity College Dublin have created a computer program that "paints" the structure of molecules in the style of famous Dutch artist, Piet Mondrian, whose beautiful artworks will be instantly recognizable to many......»»
Social contagion research explores how ant colonies regulate group behaviors
In the world of social creatures, from humans to ants, the spread of behaviors through a group—known as social contagion—is a well-documented phenomenon. This process, driven by social imitation and pressure, causes individuals to adopt behaviors.....»»
New research reveals how galaxies avoid early death
Galaxies avoid an early death because they have a "heart and lungs" which effectively regulate their "breathing" and prevent them from growing out of control, a new study suggests......»»
Novel protein found to inhibit activity of CRISPR-Cas system
In a study published in Nature on July 3, researchers from the Institute of Biophysics of the Chinese Academy of Sciences and the University of Toronto, Canada, discovered a novel anti-CRISPR protein called AcrIF25, which inhibits the activity of the.....»»
Frozen mammoth skin retained its chromosome structure
Features as small as 50 nanometers preserved in a 50,000-year-old sample. Enlarge (credit: LEONELLO CALVETTI/SCIENCE PHOTO LIBRARY) One of the challenges of working with ancient DNA samples is that damage accumulates ove.....»»
Opening the right doors: New work reveals "jumping gene" control mechanisms
International joint research led by Akihisa Osakabe and Yoshimasa Takizawa of the University of Tokyo has clarified the molecular mechanisms in thale cresses (Arabidopsis thaliana) by which the DDM1 (Decreased in DNA Methylation 1) protein prevents t.....»»
Latest European demographic data sheet highlights lasting impact of war and migration
The Russian invasion of Ukraine and the consequent displacement of millions of people will have a significant impact on the country's long-term population structure. Researchers from the Austrian Academy of Sciences, IIASA, and the University of Vien.....»»
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.....»»
Unexpected phage protein function discovered in bacteria battle
An unexpected find has enabled important progress to be made in the battle against harmful bacteria. An international team of researchers, led by Professor Peter Fineran from the University of Otago, investigated a particular protein used by bacteria.....»»
