Our bacteria are more personal than we thought, new study shows
The trillions of bacteria that call your body home—collectively known as the microbiome—appear to be unique to you, like a fingerprint. That's one conclusion of a detailed study of the gut, mouth, nose and skin microbiomes of 86 people. Over the.....»»
How cells in developing embryos change the way they use enhancers to regulate gene expression
If you look at a nerve cell, a muscle cell, or a skin cell under the microscope, they appear strikingly different. However, every cell in our body has the same DNA and has descended from a common ancestor—the fertilized egg cell. The diversity we o.....»»

Epic says Apple will reinstate developer account, clearing path for Epic Games Store on iPhone
After a whirlwind of events, Epic Games says Apple has reinstated their App Store developer account. The move clears the way for Epic to bring its Epic Games Store to the EU, avoiding the App Store structure altogether. The turnaround is somewhat une.....»»
Horizontal gene transfer: How fungi improve their ability to infect insects
Researchers at the Kiel Evolution Center have investigated for the first time in detail how a fungus important for biological plant protection can pass on an advantageous chromosome horizontally, using a previously little-studied way of exchanging ge.....»»
How water guides the assembly of collagen, the building block of all humans
Water determines life: humans are three-quarters water. An international research team led by the University of Amsterdam (UvA) has now discovered how water also determines the structure of the material that holds us together: collagen......»»
Vitamin A may play a central role in stem cell biology and wound repair
When a child falls off her bike and scrapes her knee, skin stem cells rush to the rescue, growing new epidermis to cover the wound. But only some of the stem cells that will ultimately patch her up are normally dedicated to replenishing the epidermis.....»»

Exploring the inner workings of stem cells: When location changes the message
Stem cells are the body's wellspring of renewal. They can turn into any kind of cell the body needs, from liver to skin to bone. But the well would run dry if all the stem cells transformed......»»
First atom-level structure of packaged viral genome reveals new properties and dynamics
A computational model of the more than 26 million atoms in a DNA-packed viral capsid expands our understanding of virus structure and DNA dynamics, insights that could provide new research avenues and drug targets, University of Illinois Urbana-Champ.....»»
