What Pelvis Shape Can Teach Us About Human Evolution

If you are looking for an interesting case study on human evolution, look no further than the female pelvis. The shape of the pelvis is thought to be a compromise between two opposing evolutionary pressures. On one hand, a narrow pelvis is ideal for walking on two feet, a trait that gives us a competitive edge over other species. On the other hand, a wide … Continue reading What Pelvis Shape Can Teach Us About Human Evolution

The Quest for Better Bandages Turns to Nanofibers

Our skin is a protective barrier to bacterial infection, but damage to the skin allows bacteria to enter. Normally, our immune system kills the bacteria and allows wounds to heal. However, certain diseases can overload the immune system and lead to heavy infection. Antibiotics are commonly used to treat heavy bacterial infection, but bacteria can develop drug resistance after too much exposure. A team at … Continue reading The Quest for Better Bandages Turns to Nanofibers

Hey, Can You Put That Out? My Planet is Dying

You’ve probably heard that cigarettes are bad for you, and it has always been a safe bet to assume that they’re bad for the environment too. A comprehensive analysis of the entire tobacco supply chain by researchers at the Imperial College of London shows just how devastating the industry continues to be for global environmental health. Check out Trevor Haynes’ article to learn more. Continue reading Hey, Can You Put That Out? My Planet is Dying

Signs of Life: Searching for Plants on Other Planets

If you travel into deep space and look back at Earth through a sophisticated telescope, you could measure what’s called the vegetation red edge (VRE). The vegetation red edge is a mixture of red and infrared light that is reflected by plants on Earth’s surface. Because of clouds, ice masses, and large oceans, the vegetation red edge on Earth is actually fairly small and difficult … Continue reading Signs of Life: Searching for Plants on Other Planets

The Chemistry Nobel: Evolving proteins into better medicines and biofuels

It’s that time of year – Nobel Prize season! This year, the Chemistry Nobel prize was awarded to three scientists: one half to Frances Arnold “for the directed evolution of enzymes,” and the other half to George Smith and Sir Gregory Winter “for the phage display of peptides and antibodies.” What exactly are these award-winning technologies and how have they impacted society? ‘Directed evolution of … Continue reading The Chemistry Nobel: Evolving proteins into better medicines and biofuels

Be the coolest house on the block with a fresh coat of a new polymer material

This summer, heat waves hit the Northern Hemisphere with temperatures upward of 100°F, highlighting one of the biggest current worldwide challenges: keeping buildings (and the people inside them) cool. A group of researchers from Columbia University may have an answer. They’ve designed a new material that chills buildings by reflecting sunlight. Instead of getting rid of heat that has already slipped into the building, this … Continue reading Be the coolest house on the block with a fresh coat of a new polymer material

Transposons: Your DNA that’s on the go

by Francesca Tomasi figures by Olivia Foster Rhoades Argonaut. Idéfix. Flamenco. These words invoke movement: the ancient Greek Argonauts were a band of adventurous sailors famous for their epic quests. Meanwhile, Idéfix is the name of an adventure-loving dog in the French Astérix comic book series. And finally, flamenco conjures images of vivacious dancers. You would think the similarities between Greek mythology, French comic books, and … Continue reading Transposons: Your DNA that’s on the go

Heat waves hurt your brain: the argument for window AC units

As our planet warms, the effects of heat on the human body will become important information. The human body is capable of dealing with heat, but reprieves are needed to allow our systems to rest, else our bodies become over-stressed. This reprieve often comes in the form of night, when temperatures typically  cool. During heat waves, nights remain toasty, and reprieves only exist for those … Continue reading Heat waves hurt your brain: the argument for window AC units

Bacteria snatch up foreign material using specialized arm-like structures

In order to adapt to their environments, it is important that bacteria be able to mix up their genetic code. One way that bacteria do this is by taking up bits of free-floating foreign DNA that can be released by other kinds of bacteria into their environments when they die. This process is called ‘transformation.’ The pieces of DNA can occasionally encode components that make … Continue reading Bacteria snatch up foreign material using specialized arm-like structures

ARIEL: Exploring strange new worlds and boldly observing what no telescope has observed before.

Since the first exoplanet discovery in the 1990s, scientists have learned of the diverse and abundant nature of exoplanets, having now found more than 3700. With such a large and disparate sample set, ESA (European Space Agency) has set its sights on learning how these planets form and what their chemistry is like. A new telescope, or ‘mission’, ARIEL (Atmospheric Remote-sensing Infrared Exoplanet Large-survey), has … Continue reading ARIEL: Exploring strange new worlds and boldly observing what no telescope has observed before.
