    Cell Nucleus Size Could Determine How Long You Are Going To Live, Say Scientists

    via INDEPENDENT: Once there was a mutant worm in an experiment. It lived for 46 days. This was much longer than the oldest normal worm, which lived just 22. Researchers identified the mutated gene that had lengthened the worm’s life, which led to a breakthrough in the study of ageing – it seemed to be controlled by metabolic processes. Later, as researchers studied these processes, all signs seemed to point to the nucleolus. Under a microscope, […]

  • Ten Things You Never Knew About… Biology

    Ten Things You Never Knew About… Biology

    via EXPRESS: MAY 22 is the United Nations World Biodiversity Day, marking the adoption of the Convention on Biological Diversity at the Rio Earth Summit on May 22, 1992. 1. The convention is the UN’s key document on sustainability, conservation and equitable sharing of resources. 2. The study of living organisms was first called biology in 1799. 3. Before that, the word “biology” was used to refer to biographical writing. 4. The biggest flower in the […]

  • How One Cell Gives Rise To An Entire Body

    How One Cell Gives Rise To An Entire Body

    via Science: One of biology’s great mysteries is how a single fertilized egg gives rise to the multitude of cell types, tissues, and organs that fit together to make a body. Now, a combination of single-cell sequencing technologies and computational tools is providing the most detailed picture yet of this process. In three papers online in Science this week, researchers report taking multiple snapshots of gene activity in most of the cells in developing zebrafish or […]

    Life 2.0: Inside The Synthetic Biology Revolution

    via Cosmos: Imagine a future where synthetic jellyfish roam waterways looking for toxins to destroy, where eco-friendly plastics and fuels are harvested from vats of yeast, where viruses are programmed to be cancer killers, and electronic gadgets repair themselves like living organisms. Welcome to the world of synthetic biology, or ‘synbio’, where possibilities are limited only by the imagination. Its practitioners don’t view life as a mystery but as a machine – one that can […]

  • Plants, Fungi and Bacteria Work Together to Clean Polluted Land

    Plants, Fungi and Bacteria Work Together to Clean Polluted Land

    via ScienceDaily: Highly complex interactions among roots, fungi and bacteria underlie the ability of some trees to clean polluted land, according to a novel study by bioinformatics and plant-biology experts from McGill University and Université de Montréal. Fast-growing trees, such as willows, are known to tolerate and even rejuvenate soil contaminated with petroleum by-products or heavy metals. The clean-up of soil in this way is known as phytoremediation, and the process is commonly attributed to “secondary […]

  • Artificial and Biological Cells Work Together as Mini Chemical Factories

    Artificial and Biological Cells Work Together as Mini Chemical Factories

    via Science Daily: Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. The system, created by a team from Imperial College London, encapsulates biological cells within an artificial cell. Using this, researchers can harness the natural ability of biological cells to process chemicals while protecting them from the environment. This system could lead to applications such as cellular ‘batteries’ […]

  • Scientists Link Genes to Brain Anatomy in Autism

    Scientists Link Genes to Brain Anatomy in Autism

    via ScienceDaily: A team of scientists at the University of Cambridge has discovered that specific genes are linked to individual differences in brain anatomy in autistic children. Previous studies have reported differences in brain structure of autistic individuals. However, until now, scientists have not known which genes are linked to these differences. The Cambridge team analysed magnetic resonance imaging (MRI) brain scans from more than 150 autistic children and compared them with MRI scans from similarly […]

  • How Exercise May Help the Memory Grow Stronger

    How Exercise May Help the Memory Grow Stronger

    via The New York Times: Exercise may help the brain to build durable memories, through good times and bad. Stress and adversity weaken the brain’s ability to learn and retain information, earlier research has found. But according to a remarkable new neurological study in mice, regular exercise can counteract those effects by bolstering communication between brain cells. Memory has long been considered a biological enigma, a medley of mental ephemera that has some basis in material […]

    Surprise Finding Points to DNA’s Role in Shaping Cells

    via ScienceDaily: As a basic unit of life, the cell is one of the most carefully studied components of all living organisms. Yet details on basic processes such as how cells are shaped have remained a mystery. Working at the intersection of biology and physics, scientists at the University of California San Diego have made an unexpected discovery at the root of cell formation. As reported in the journal Cell on Feb. 8, 2018, biologists Javier […]

  • Researchers Map Genetic ‘Switches’ Behind Human Brain Evolution

    Researchers Map Genetic ‘Switches’ Behind Human Brain Evolution

    via Laboratory Equipment : UCLA researchers have developed the first map of gene regulation in human neurogenesis, the process by which neural stem cells turn into brain cells and the cerebral cortex expands in size. The scientists identified factors that govern the growth of our brains and, in some cases, set the stage for several brain disorders that appear later in life. The human brain differs from that of mice and monkeys because of its large […]
