Ecology03/28/2014 Do Clouds Need Passports?
Dust and Biological Aerosols from the Sahara and Asia Influence Precipitation in the Western U.S. 
Creamean et al. 
 
Have you ever stopped to look at the clouds moving across the sky? How did they get there? And, where do they go after they finish dropping precipitation onto the land below them? Aerosol particles, either dust or biological,...
Biology02/28/2014 How Dynamic is your Virus?
Population Dynamics of Immune Responses to Persistent Viruses
Nowak and Bangham
 
When exposed to the same virus, why do some people become sick while others remain healthy?  The virus is the same, suggesting that there must be a difference in the immune response of different hosts.  What factors determine this, and why do they differ from person to...
Ecology01/31/2014 Lemmings: They’re What’s for Dinner
Cyclic Dynamics in a Simple Vertebrate Predator-Prey Community.  
Gilg et al.
 
Scientific studies often involve more than one discipline. In this case of lemming population dynamics, scientists use both ecology-related methodology to collect data in Greenland, and mathematical equations to construct a predictive model. Similar to the cyclic...
Biology12/27/2013 The Art of DNA
DNA Origami with Complex Curvatures in Three-Dimensional Space     
Han et al. 

Origami, the Japanese art of paper folding, transforms a 2D piece of paper into a 3D masterpiece.  While there are a limited number of ways to fold origami paper, the variety in the sequence of the folding results in...

Biology10/18/2013 What the Pelvis Can Teach Us About Evolution

Adaptive Evolution of Pelvic Reduction in Sticklebacks by Recurrent Deletion of a Pitx1 Enhancer.  Chan et al

Talk of evolution research most often conjures up images of Darwin and his finches.  However, the Stickleback fish, a lesser known animal model that can exhibit evolutionary changes in as few as ten generations, allows scientists to direct a much more modern study of...

Physics10/18/2013 Experiments Einstein Could Only Dream Of
 
Measurement of the Instantaneous Velocity of a Brownian Particle.
Li et al.  
 
Sometimes, scientists have to wait for technology to catch up.  Albert Einstein, arguably one of the greatest scientist in modern history, fell victim to this himself. While working on Brownian motion, Einstein proposed ideas that he did not yet have...
 Science Translational Medicine: 3 August 2011Biology10/18/2013 A New Diagnostic Strategy for Prostate Cancer

Urine TMPRSS2:ERG Fusion Transcript Stratifies Prostate Cancer Risk in Men with Elevated Serum PSA.  Tomlins et al

During their lifetime, 18% of all American men will get prostate cancer, a slow-growing cancer which rarely causes symptoms.  Since both surgery and radiotherapy commonly cause harmful side effects, it is important that only patients with aggressive cancers are...

Chemistry07/31/2012 Replicating Photosynthesis

Wireless Solar Water Splitting Using Silicon-Based Semiconductors and Earth-Abundant Catalysts.  Reece et al.  

As an energy source, the sun is capable of providing enough power for all of our energy needs.  Currently, we are unable to harness this power and store it until it is needed in a manner that is cost competitive with traditional energy sources.  How can scientists and...

Biology07/31/2012 Heads or Tails?

Polarized notum Activation at Wounds Inhibits Wnt Function to Promote Planarian Head Regeneration.  Petersen and Reddien.

When compared with starfish, humans seem to be the more advanced species.  Humans have a complex nervous system, the ability to walk upright, and opposable thumbs.  However, one category where the starfish reigns superior is in regeneration, or the ability to...

Biology07/31/2012 A Tiny Fungus is Causing Big Problems

An Emerging Disease Causes Regional Population Collapse of a Common North American Bat Species.  Frick et al. 

Despite their size, ecosystems are fragile and easily disrupted. The introduction of a novel disease can have serious impacts on naïve wildlife populations, which in turn will affect the strength of the entire ecosystem.  White-nose syndrome, a fungal infection affecting...
