Divide and Conquer! A parasitic worm's key to survival

You may have already forgotten about Halloween, but the recent discovery of a new social organization of body-snatching parasites might be enough to send shivers down your spine!  Trematodes are a clade of worms that are almost exclusively parasites of snails and mollusks (with the notable exception of schistosomes); one species is the cause of

The Wonders of Human Milk!

It's a girl (or boy)! Your bundle of joy is finally here. Stepping into parenthood, life is magical.  But it is not all sunshine and roses either with the constant cleaning, frequent feedings and sleepless nights. The baby falling sick on top of it, is your worst fear. No wonder you find yourself paranoid, sterilizing

Shining some light on the science of vampires

This Halloween, as you see kids dressed up as zombies or witches, threatening neighbors into giving them candy it's easy to forget that these terrifying creatures once had a less sugary purpose: in the absence of modern science, our ancestors needed a supernatural technique to explain the plagues and diseases that reason couldn't. One of

Saving the world’s seeds, ex situ

The imposing structure of the Svalbard seed bank is familiar to many. This “doomsday” vault (ahem, already breached by climate change) is humanity's last resort for preserving the seeds of our crops and plants. But how did this bastion of biodiversity arise? Nikolai Vavilov, a 20th century Russian agronomist and geneticist, established the first modern

Last but not yeast, the beer necessities

Fermentation is the process in which sugar is consumed by microbes and converted into another chemical. In the case of brewer's yeast (Saccharomyces cerevisiae), the fungus responsible for nearly all alcoholic beverages, sugar is eaten and converted to alcohol, phenols, and esters. Other fungi and bacteria have been in use for centuries, but their use

Photosynthesis & waffles: how plant sap gets on our breakfast plates

Maple syrup is a staple in Western breakfast culture. True maple syrup – as opposed to the thick corn syrup imitation that sits in many American diners – comes from a variety of trees, mostly  the sugar maple. But this breakfast condiment is more than just goo that happens to ooze out of a plant

Fossilized Ebola is Hiding in Your Pet Hamster's DNA!

Ebolavirus is one of the most infamous disease causing pathogens of the modern era. The 2014 Ebola outbreak in West Africa was the largest outbreak of ebolavirus to date, with over 28,000 suspected cases and 11,000 deaths. Ebolavirus is just one member of the Filoviridae virus family. These viruses are colloquially referred to as Filoviruses

The Solar Power of the Sunflower

This article is part of our brand new Athens Science Observer interview series. We are conducting interviews with established scientists in order to get first person accounts of exciting research and hear the stories of those who are making a difference. You may have heard that sunflowers can track the sun during the day, but

Scouting for the Next Top Model (Organism)

Here's a valid question: if it's a human condition or disease we're interested in, why do we study flies, plants or bacteria? It's a question that researchers often have to answer: whether it be for grant funding or to their in-laws over Thanksgiving dinner. Certainly, no one wants to hear—or vote for— tax dollars aimlessly

From Social Stigma to Health Sensor: Scientific Tattooing

Tattoos, the artistic insertion of pigment into the skin as a form of body modification, has been around for quite a while, with the earliest preserved example from around 3300 BC. These tattoos comes from Ötzi the Iceman, a preserved human found in the Alps between Austria and Italy in 1991. The tattoos were of

Viruses: The Original Genome Editors

  Viruses stealthily spread among us, commandeering our very cells and waging a relentless war with our immune systems. You know them for everything from the common cold and flu to catastrophic outbreaks of HIV and Ebola. At the very least, they’ve probably ruined your plans once or twice. But did you know that a

Plant Cells, an Unculturable Mystery

The simplest unit in biology is the cell. This central tenet has remained true since the coining of the term 'cell' in 1665 by Robert Hooke. Cells have enabled multicellular organisms to conquer every part of the planet, enabling cell line specialization and the formation of more complex organisms. Multicellularity allowed organisms to thrive by
