    How The Coronavirus Attacks Your Lungs | KQED / Deep Look (2020)

    May 7, 2020 at 8:58 am / Human Nature, Molecular Nature, PBS Nature

    DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. In this special episode they are doing a vital job by disseminating reliable information on SARS-CoV-2 virus which leads to COVID-19 respiratory disease. The BBC Documentary The Hidden Life of the Cell has done a wonderful job of providing a visual story telling by animating series of events leading to an Adenovirus infection. You can also see how different coronaviruses […]

    Mediterranean Stony Corals (Phyllangia americana mouchezii) – Mert Gökalp (2018)

    When we talk about corals we always conjure up the iconic image of highly fragile tropical reef-building symbiotic organisms in crystal clear shallow waters. The stony corals living in cold waters are striking in this matter. They show that this symbiotic relationship between the two evolutionarily distant partner organisms can break down (coral bleaching) or never evolve when conditions are less than optimal. The Mediterranean is a rather nutrient poor sea with low productivity. Lacking a photosynthetic partner stony corals […]

  • Structure of a Spliceosome: Molecular Framework for Understanding Pre-mRNA Splicing – Beauty of Science

    Structure of a Spliceosome: Molecular Framework for Understanding Pre-mRNA Splicing – Beauty of Science

    May 2, 2020 at 8:48 am / Molecular Nature

    One Gene-One Peptide Hypothesis was a bold statement proposed by Edward Tatum and George Beadle in 1941 heralding the nascent field of molecular genetics. The proposal was long before we knew anything about the nature and structure of the DNA. It was rather vague how a gene encoded a protein. The Central Dogma of biology was coined by Francis Crick in late 1950s but the intermediate molecule known as the messenger RNA was identified (?) in 1960 by Arthur Pardee, […]

    ATP Synthase in Action – HarvardX / BioVisions

    April 27, 2020 at 3:09 pm / Molecular Nature, Video

    ATP is a universal energy storing molecule in biological systems. How does life generate ATP from ADP? Similarly, how does life consume it on an industrial scale in membrane bound systems such as mitochondria and chloroplasts? ATP synthase (or ATPase depending on which catalytic direction you look at it) enzyme is a hugely interesting molecular structure. Yes it most certainly is a bi-directional turbine. It is one of the few rotatory molecular structures life has evolved such as the flagella […]

    Electron Transport Chain – HarvardX / BioVisions (2013)

    Understanding molecular nature of life is not easy without informative scientific visualizations. Distillation of this rich body of information generated over decades or even century long research into a visual medium can be key to grasp complexities of subcellular structures. Take the Central Dogma of biology for instance. The Central Dogma animation distills more than half a century of intense laboratory research that started with Rosalind Franklin and Raymond Gosling’s extraordinarily historic X-ray diffraction photograph in 1952. Photo 51 was […]

  • Eye of the Pangolin – Pangolin.Africa (2019)

    Eye of the Pangolin – Pangolin.Africa (2019)

    April 2, 2020 at 11:21 am / Ecological Documentaries, Evolution, Natural history, Video, Wildlife Documentaries

    The etymological origin of the name pangolin comes from the Malay word pengguling. It means “one who rolls up”. The animal has at least eight species with a wide geographical distribution ranging from Africa to Indian subcontinent and southeast Asia including Malayan Archipelago and Indonesia. Unfortunately we know very little about this highly elusive animal and its existence is under threat. Scaly anteaters are quite unusual among mammals since their skin is covered by large and overlapping keratinized scales hugely […]

    How Coronaviruses Get into Cells – Tom Goddard (2020) / ChimeraX

    February 20, 2020 at 11:45 am / Molecular Nature, Video

    Tom Goddard is the developer of a fantastically successful free molecular visualization program ChimeraX in the University of California at San Francisco with support from the National Institute for Allergy and Infectious Diseases and the National Institute of General Medical Sciences. Here in this augmented reality projection, he explains how coronaviruses manage to enter cells of the host and take over the machinery which spark a viral infection. He takes a peek at the HIV packing structure and delves into […]

    Mitochondria: The Cell’s Powerhouse – HarvardX / BioVisions (2010)

    February 19, 2020 at 8:48 pm / Molecular Nature

    Mitochondria is one of the defining features of eukaryotic cells. It is a key innovation in life’s evolution. Here in this video by BioVisions, HarvardX outlines this organelle’s fascinating biology with informative visualizations that help grasp its molecular nature. However, before you continue, you might be interested in a visualization by XVIVO as a great primer to this video for cytological reasons. XVIVO has teamed up with Google to create a stunning 3-D immersive visualization of subcellular compartments inside a […]

    Gear CDC’s Disease Detectives Use – Wired Magazine (2018)

    January 28, 2020 at 10:00 pm / Human Nature, Video

    Disease and pandemics are scary. As the world is shaking with the news of a new corona virus outbreak in China it is informative to take a look into gear used by “the disease detectives” ie. Center for Disease Control and Prevention. The movie Contagion (2011) has done a great job for educating public by depicting a rather probable scenario of a viral outbreak largely based on the SARS outbreak of 2003. The hugely successful BBC documentary The Hidden Life […]

    As the world is shaking with the news of a new corona virus outbreak in China, researchers have quickly identified the potential source of 2019-nCoV based on the spike forming glycoprotein structure. Just like the hugely informative movie Contagion (2011) depicting a realistic scenario this new virus was a bizarre sounding recombinant. The corona virus SARS-CoV-2 appeared to be a recombinant of a bat and a snake virus. At first, you may naturally ask how could this weird merger have […]
