    Image result for Study uncovers genetic switches that control process of whole-body regeneration
    Scientists have uncovered a DNA switch that could give humans the ability to grow back their limbs. Animals like salamanders or geckos can shed parts of their bodies to escape predators and form new parts. The study examined the genetic switches in three-banded panther worm

    Researchers are shedding new light on how animals perform whole-body regeneration, and uncovered a number of DNA switches that appear to control genes used in the process.
    Planarian worms, jellyfish, and sea anemones can actually regenerate their entire bodies after being cut in half.

    Led by Assistant Professor of Organismic and Evolutionary Biology Mansi Srivastava, a team of researchers is shedding new light on how animals pull off the feat, and uncovered a number of DNA switches that appear to control genes for w...

    A Cosmic Bat in Flight

    March 16, 2019, Categories  Health/Medical, Biology/Biotechnology

    Hidden in one of the darkest corners of the Orion constellation, this Cosmic Bat is spreading its hazy wings through interstellar space two thousand light-years away. It is illuminated by the young stars nestled in its core — despite being shrouded by opaque clouds of dust, their bright rays still illuminate the nebula. Too dim to be discerned by the naked eye, NGC 1788 reveals its soft colours to ESO’s Very Large Telescope in this image — the most detailed to date.

    ESO’s Very Large Telescope (VLT has caught a glimpse of an ethereal nebula hidden away in the darkest corners of the constellation of Orion (The Hunter) – NGC 1788, nicknamed the Cosmic Bat...

    Follow-up study in people underway. Green tea cut obesity and a number of inflammatory biomarkers linked with poor health in a new study. Mice fed a diet of 2% green tea extract fared far better than those that ate a diet without it, a finding that has prompted an upcoming study of green tea’s potential benefits in people at high risk of diabetes and heart disease.

    The benefits seen in the new study, published in the Journal of Nutritional Biochemistry, appear to stem from improved gut health, including more beneficial microbes in the intestines of the mice and less permeability in the intestinal wall – a condition typically called “leaky gut” in people.

    “This study provides evidence that green tea encourages the growth of good gut bacter...

    Danger of Vitamin B12 Deficiency

    March 14, 2019, Categories  Health/Medical, Biology/Biotechnology

    Rice University researchers found vitamin B12 promotes survival during infection by improving mitochondrial health. The expression of a fluorescent protein (top left) reflects buildup of a toxic metabolic product, propionate, in mitochondria on diets low in B12, as compared (bottom left) to those receiving sufficient B12. Mitochondrially targeted fluorescent protein (center) reveals fragmentation of mitochondria when B12 is low, and dead worms stained with fluorescent dye (bottom right) demonstrate the decreased survival rate of worms infected by the pathogen Pseudomonas aeruginosa.
