    Scientists have developed a method that can determine an organism’s biological age with unprecedented precision. Researchers expect new insights into how the environment, nutrition, and therapies influence the aging process.

    Using the model organism Caenorhabditis elegans, researchers at the University of Cologne have developed an ‘aging clock’ that reads the biological age of an organism directly from its gene expression, the transcriptome...

    An illustration of the egg crate electronic structure, shown between two mirrors so that the red laser light resonates. The polaritons, trapped in the pockets, are represented by the sum of their parts: a green exciton, with electron and hole shown inside, attached to a red lightwave. Even with just a few excitons in the wells, the energy required to add a new one begins to jump

    Earth has a Hot New Neighbor – and it’s an Astronomer’s Dream

    A rocky planet discovered in the Virgo constellation could change how we look for life in the universe. It could be our best chance yet of studying rocky planet atmospheres outside the solar system, a new international study involving UNSW Sydney shows.

    The planet, called Gliese 486b (pronounced Glee-seh), is a ‘super-Earth’: that is, a rocky planet bigger than Earth but smaller than ice giants like Neptune and Uranus. It orbits a red dwarf star around 26 light-years away, making it a close neighbour — galactically speaking.

    With a piping-hot surface temperature of 430 degrees Celsius, Gliese 486b is too hot to support human life...

    The Right ‘5-a-day’ Mix is 2 Fruit and 3 Vegetable Servings for Longer Life

    March 5, 2021, Categories  Health/Medical, Biology/Biotechnology

    Studies representing nearly 2 million adults worldwide show that eating about five daily servings of fruits and vegetables, in which 2 are fruits and 3 are vegetables, is likely the optimal amount for a longer life, according to new research published today in the American Heart Association’s flagship journal Circulation.

    Diets rich in fruits and vegetables help reduce risk for numerous chronic health conditions that are leading causes of death, including cardiovascular disease and cancer. Yet, only about one in 10 adults eat enough fruits or vegetables, according to the U.S. Centers for Disease Control and Prevention.

    “While groups like the American Heart Association recommend four to five servings each of fruits and vegetables daily, consumers likely get inconsistent messages ...
