How Do Algae Biofuels Compare to Diesel in Real Engines?

It turns out that algae, the green fuzzy stuff that covers rocks, coats shorelines, and thrives in swampy areas, might be the renewable fuel source we’ve been searching for. Algae and microalgae are photosynthetic organisms (they generate energy from sunlight and CO2) naturally found in freshwater ecosystems. Researchers in Cuba and Belgium have assembled a […]

The Latest Cutting-Edge Water Filtration Technique

Nature, for all its genius, is inherently lazy. Living organisms appear to have two priorities — survive long enough to reproduce and spend as little energy as possible doing so.  Over generations, a species will make small tweaks to better adjust itself to survive to its environment. There are analogies to this in our human-scale […]

More Evidence for the Brain-Gut Connection

You’re out for a run on your favorite trail, and you hear something rustle in the bushes. You immediately jump to attention, eyeing a snake. Your body’s automatic reaction to the snake can be attributed to your amygdala. The amygdala is a region of the brain where our fear response takes place. For example, if […]

Chess might help you become better at math, but not for the reasons you think.

Chess is often a metaphor for life, love, and sports. This popular board game has found favor among all education levels, ages, and backgrounds. Now, there may be room for it in the mathematics classroom as a strategy for increasing student engagement. Math anxiety and poor math performance among young students is common, and science […]

But every story has its villain. Drop that smart bracelet, and your device won’t be covered by warranty. There’s always fine print at the back of the box that […]

La luna de Saturno Encélado podría tener condiciones para la vida

La nave espacial Cassini orbitando alrededor de Saturno realizó un asombroso descubrimiento en la luna Encélado. En una serie de sobrevuelos cercanos a un chorro continuo de partículas heladas se encontró hidrógeno molecular ( H2 ). Dicho chorro, recibe el nombre de géiser y dispara las moléculas cientos de millas en el espacio desde las […]

Word of the Day: Gravitational Wave

A gravitational wave is a ripple in space-time caused by intense gravitational forces in space. Not to be confused with with a gravity wave, which is an oscillation (back and forth wavelike movement) between two substances of different densities. Ocean waves are an example of a gravity wave, whereas a gravitational wave is something much […]

Word of the Day: RuBisCo

Water is flowing effortlessly, the temperature in just the right range and possibly filled with life forms. Intriguing? This hypothetical world could have been our neighbor Mars. Dr. Dimitra Atri from Blue Marble Space believes so. In his […]

The Information Flow of Life

Atoms make molecules and molecules make proteins, like the keratin in your hair or hemoglobin in your blood. These proteins interact in complex ways to create movement, metabolism, consciousness, and everything we call life. But there is a vast divide in complexity between the simplest amoeba and a human being. How do those chemicals self-assemble […]
