Laboratory and natural strains of intestinal bacterium turn out to have similar mutational profiles
Understanding mutational processes in a cell offers clues to the evolution of a genome. Most actively, mutation processes are studied in human cancer cells, while other genomes are often neglected......»»
Rich molecular language guides tiny liquid droplet formation in cells
Peering into a biological cell reveals a bustling microscopic world. The workhorses within this realm are specialized structures called organelles that perform vital cellular functions. Curiously, some organelles defy accepted convention: Instead of.....»»
Researchers explore raw materials and firing technology for porcelain from late sixth-century Xing kiln
In the process of firing ceramics, the appearance, structure and properties of ceramics are determined by raw materials and firing technology, so the study of raw materials and firing technology of ancient ceramics has always been a very important ar.....»»
Ancient scroll reveals new story of Plato"s death—here"s why you should be suspicious of it
Plato of Athens (429–347 BC) may be one of the most famous philosophers of all times. He was the thinker who came up with the "theory of forms" and founded the first academic institution. Yet we know little about his life, such as how he died, or w.....»»
Researchers develop new AI tool for fast and precise tissue analysis to support drug discovery and diagnostics
A team of scientists from A*STAR's Genome Institute of Singapore (GIS) and Bioinformatics Institute (BII) has developed a new AI software tool called "BANKSY" that automatically recognizes the cell types present in a tissue, such as muscle cells, ner.....»»
Collaboration identifies rare nuclear decay in long-lived potassium isotope
Some nuclei of certain elements decay radioactively into nuclei of different elements. These decays can be useful or annoying depending on the context. This is especially true for potassium-40. This isotope usually decays to calcium-40, but about 10%.....»»
Astronomers observe elusive stellar light surrounding ancient quasars
MIT astronomers have observed the elusive starlight surrounding some of the earliest quasars in the universe. The distant signals, which trace back more than 13 billion years to the universe's infancy, are revealing clues to how the very first black.....»»
Beautifully crafted Roman dodecahedron discovered in Lincoln—but what were they for?
Roman dodecahedra are something of an enigma: there is no known mention of these 12-sided, hollow objects in ancient Roman texts or images. First discovered in the 18th century, around 130 dodecahedra have been found across the Roman Empire, although.....»»
Assyriologist claims to have solved archaeological mystery from 700 BC
Ancient symbols on a 2,700-year-old temple, which have baffled experts for more than a century, have been explained by Trinity Assyriologist Dr. Martin Worthington......»»
Novel chemical tool for understanding membrane remodeling in the cell
In a study published in Proceedings of the National Academy of Sciences, Umeå researchers describe a natural product-like molecule, Tantalosin, that inhibits interaction between two proteins in complexes that reshape membranes inside the cell......»»
New discovery of a mechanism that controls cell division
Researchers at Umeå University, Sweden, have discovered that how a special protein complex called the Mediator moves along genes in DNA may have an impact on how cells divide. The discovery may be important for future research into the treatment of.....»»
The Eta Aquarid meteor shower, debris of Halley"s comet, peaks this weekend. Here"s how to see it
The Eta Aquarid meteor shower, remnants of Halley's comet, peaks this weekend. And with just a waning crescent moon in the sky, it should be visible......»»
Maya used hallucinogenic plants in rituals to bless their ball courts
eDNA analysis found traces of xtabentum, as well as lancewood, chili peppers, and jool. Enlarge / A decorative ring made from carved stone is embedded in the wall of a ballcourt in the ancient Maya city of Chichen Itza. (credit:.....»»
Researchers develop "founding document" on synthetic cell development
Cells are the fundamental units of life, forming the variety of all living things on Earth as individual cells and multicellular organisms. To better understand how cells perform the essential functions of life, scientists have begun developing synth.....»»
Nano-drugs hitching a ride on bacteria could help treat pancreatic cancer
Many pancreatic tumors are like malignant fortresses, surrounded by a dense matrix of collagen and other tissue that shields them from immune cells and immunotherapies that have been effective in treating other cancers. Employing bacteria to infiltra.....»»
For the ancient Maya, cracked mirrors were a path to the world beyond
Some people fear that breaking a mirror can lead to seven years of misfortune. The history of this superstition may go back to the ancient Greeks and Romans, who ascribed mysterious powers to reflected images......»»
Bioreactor processes and cryotechnologies improve active ingredient tests using human cell cultures
Many new drug candidates end up failing because they cause serious side effects in clinical trials even though lab tests involving cell cultures have been successful. This is a common occurrence if the cells used come from animal tissue, for example......»»

Cell contraction drives the initial shaping of human embryos, study finds
Human embryo compaction, an essential step in the first days of an embryo's development, is driven by the contractility of its cells. This is the finding of a team of scientists from CNRS, Institut Curie, Inserm, AP-HP and the Collège de France. Pub.....»»
Organic electrochemical transistors: Scientists solve chemical mystery at the interface of biology and technology
Researchers who want to bridge the divide between biology and technology spend a lot of time thinking about translating between the two different "languages" of those realms......»»
