I want to make cutting-edge biology research accessible to those who do not have the background, and to attempt to illuminate why it is so important that we spend billions of dollars each year to study how sex is determined in a nematode, how a particular species of tree disperses its seeds, or what changes take place when a yeast cell ages and dies. These studies may not seem relevant — but I will try to convince you, along with myself, that they are, and how they could change the way we live.

Dimethylsulfide. Does that word mean anything to you? “Why yes,” you organic chemistry nerds may say, “It clearly is a molecule of sulfur with two methyl groups attached.” That’s as far as I could have gotten – until this past week, when I inundated myself with information on dimethylsulfide (DMS) due to a paper published [...]...

An underwater photographer has his camera stolen by a thieving octopus, who flees with the device, filming along the way. Sure, he was filming his own flesh, but baby’s first movie isn’t too shabby.
People love to talk about octopus “intelligence.” The photographer specifies that the octopus wasn’t attacking him, but just wanted to steal [...]... Read more »

In any high school biology class1, we learn that isolation is key to the evolution of species. For example, take Australia, where an array of marsupials such as koalas and kangaroos reproduce like no other animals on the planet. Isolation on a continental island allowed ancestral marsupials to evolve gestation via pouch, a trait which [...]... Read more »

Nature-inspired design: this phrase makes me think of shark-skin swimsuits, velcro, and an endless assortment of coffee tables using natural knots and tree branches. There is logic behind design reliant upon natural elements. After all, organisms have been undergoing evolution for millions of years for the sake of efficiency. If anyone knows how to [...]...

I have a tendency to root for the underdog. I rooted for the Phillies throughout the 90s, when my heroes Lenny Dykstra and Darren Dalton could rarely lead them to a win.

I rarely think about how invasive species affect genetics.

No one can deny that the field of science is undergoing explosive growth.

To some people, a volcanic eruption means “Ahh! Run! Hot Lava!” But to others, it means “SCIENCE!” To those studying hydrothermal vent communities, that is (and a wide berth of geologists). Hydrothermal vents are cracks in the seafloor formed when tectonic plates spread apart, which spew out hot, mineral-rich water from the interior of the [...]... Read more »

It’s been a slow few weeks around here at Culturing Science. It’s due to a little bit of writer’s block, but mainly it’s just the beautiful weather keeping me outdoors and away from the computer. Hopefully you’ve been outside so much that you haven’t noticed.

When I read updates on blogs or the news about the BP oil spill, my expression is generally very serious: furrowed brow, pursed lips which I’m probably chewing in alternation with gnawing a nail.

I have been fearful of molecular biology for most of my life.

Trying to capture the movement of a colony of leaf-cutter ants in a single photo is nearly impossible in my (amateur) experience.

Biologists and taxonomists love to put organisms into categories to help us organize the complicated living world.

Every thirteen years they come.
