Eye color and Tyndall Effect

Image
According to wiki:"Eye color is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye iris and the frequency-dependence of the scattering light by the turbid medium in the stroma of the iris." Eye color often is the genetic trait that fascinates parents the most as a child develops. Will the child's eyes be black, brown, blue, gray, green, hazel or some combination of colors?  Human eye color originates with three genes, two of which are well understood. These genes account for the most common colors — green, brown, and blue. Other colors, such as gray, hazel and multiple combinations are not fully understood or explainable at this time. The pigmentation of the iris depends on the concentration of melanin in the iris pigment epithelium(located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma.The appearance of blue and green, a...

A new bioglue that could seal wounds in 60 seconds

Image
Scientists have developed an elastic, adhesive surgical glue that could transform emergency treatments by sealing up critical wounds in the skin or the organs, without the need for staples or sutures.The gel is based on methacryloyl-substituted tropoelastin (MeTro for short), a hybrid elastic protein, and can be squirted onto internal and external wounds to seal them up and encourage healing.According to the international team of researchers behind the glue, it could quite literally be a lifesaver, sealing up wounds in 60 seconds without stopping the natural expanding and relaxing of the organ or the skin it's applied to.To be clear, for now the trials are limited to animal models. But human trials are in the works, and the results to date are incredibly promising. "The beauty of the MeTro formulation is that, as soon as it comes in contact with tissue surfaces, it solidifies into a gel-like phase without running away," says one of the team, Nasim Anna...

Icy materials in space could behave like liquids at low temperatures and under ultraviolet light, suggests new research

Image
" Interstellar ice is believed to be a cradle of complex organic compounds, commonly found within icy comets and interstellar clouds, in association with ultraviolet (UV) irradiation and subsequent warming. We found that UV-irradiated amorphous ices composed of H 2 O, CH 3 OH, and NH 3 and of pure H 2 O behave like liquids over the temperature ranges of 65 to 150 kelvin and 50 to 140 kelvin, respectively. This low-viscosity liquid-like ice may enhance the formation of organic compounds including prebiotic molecules and the accretion of icy dust to form icy planetesimals under certain interstellar conditions. " According to the researchers from Hokkaido University in Japan, when the deep space conditions are right, this particular type of ice can attract and hold dust and debris, starting off a chain reaction that ends up with something like Jupiter . "The liquid-like ice may help dust accrete to planets because liquid may act as a glue," says lea...
