Using optical microscopy to take a look beneath the skin of "surfactant onions"
Surfactant onions form when layers of surfactant molecules organize around each other into a sphere. They are easily pictured by thinking of their vegetable namesake. Until now it has not been clear whether surfactant onions are perfect layered struc.....»»

Archaeologists suggest Neolithic Scandinavians may have used skin boats to hunt, travel and trade
Recent research by Dr. Mikael Fauvelle and his colleagues, published in the Journal of Maritime Archaeology, proposes that the neolithic Pitted Ware Culture (PWC) may have used skin boats to conduct trade, travel, fishing, and hunting activities......»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»

A window into the body: New technique makes skin invisible
Researchers have developed a new way to see organs within a body by rendering overlying tissues transparent to visible light. The counterintuitive process—a topical application of food-safe dye—was reversible in tests with animal subjects, and ma.....»»
How fish guts might play a role in future skin care products
There are some pretty strange ingredients in cosmetics and skin care products. One example is snail mucin—also known as snail slime—which is used for its moisturizing and antioxidant properties. But researchers reporting in ACS Omega might have f.....»»
The Earth"s inner core is an enduring mystery: Here"s how researchers are starting to solve it
Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface. In fact, without it we'd be unlikely to even exi.....»»
Algorithm maps protein degradation patterns to improve infection diagnosis and treatment
Peptides are small fragments of proteins, mainly found in the skin and mucous membranes. Some peptides act as a barrier, protecting the body against infections by fighting off microorganisms like bacteria, viruses, and other pathogens, while others p.....»»
Beyond point-to-point triangulation: Dynamic 3D imaging under global illumination
