    Return of the Cicadas – Samuel Orr (2013)

    Cicadas are Hemipterans (true bugs). The genus Magicicada groups 13-year and 17-year periodical cicada species of eastern North America. The Spring of 2020 corresponds to the emergence of Brood IX of periodical cicadas in North Carolina, Virginia and West Virginia. Such emergences are spectacular feats of nature. After living underground feeding with tree roots for 13-years or 17-years (depending on the brood type) the adult insects dig themselves out synchronously in massive numbers to change their exoskeletons, mate and die. […]

  • The Ancient Oak Tree that Taught the World a Lesson – BBC (2020)

    The Ancient Oak Tree that Taught the World a Lesson – BBC (2020)

    The Turner’s oak is a hybrid of the European oak (Quercus robur) and the Mediterranean holm oak (Quercus ilex). It is a prime example of a hybrid that exhibits blended characteristics of its progenitors: a semi-evergreen tree. Grown out in the open field for centuries, this tree experienced no competition from others and developed a dome shaped canopy. The tree was grown at the Holloway Down Nursery of Spencer Turner, Leyton, Essex, UK. In 1783, it caught the attention of […]

    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

    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

    ATP Synthase in Action – HarvardX / BioVisions

    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)

    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)

    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 […]

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

    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 […]

    Snakes in a Cave – Nate Dappen & Neil Losin (2014)

    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 […]
