Biological11/15/2013 Jumping Genes!

Dosage Compensation via Transposable Element Mediated Rewiring of a Regulatory Network.  Ellison and Bachtrog

Barbara McClintock's discovery of transposons, mobile genetic elements, took a while to become widely accepted by the scientific community. This study, investigating sex chromosomes, could be considered as the "...

Biological09/26/2014 Do you remember being born?
Hippocampal Neurogenesis Regulates Forgetting During Adulthood and Infancy.  Akers et al.
 
Why do we have so much trouble remembering our own infancy? This phenomenon, known as infantile amnesia, occurs in humans as well as many animal species. Does the synthesis of...
Physical09/12/2014 Chemical Reactions Up Close
Direct Imaging of Covalent Bond Structure in Single-Molecule Chemical Reactions de Oteyza et al. 
 
How exactly do chemicals react? How do molecules break and form new bonds? How do we know what the products of chemical reactions look like? In this study, the organic hydrocarbon, phenylene-1,2-ethynylene (C26H14) is visualized at the...
Biological08/29/2014 New Neurons Stand Out From the Crowd
Emergence of Individuality in Genetically Identical Mice
Freund et al.
 
We have noticed for a long time that identical twins, who share the same genes and grew up in the same family, do not act exactly the same. But, since we also know that our environment and genetic makeup influence how our bodies and brains develop, where do...
Biological07/25/2014 Deep Clean Your Brain in One Easy Step!
Sleep Drives Metabolite Clearance from the Adult Brain.  Xie et al.
 
The brain is highly metabolically active and produces waste which must be removed before it accumulates and begins to harm the brain. This paper links sleep with the removal of these dangerous metabolic by-products. The authors inject fluorescent dyes into the cerebrospinal fluid (CSF) of...
Biological06/27/2014 Cracking the Armor
Crocodile Head Scales Are Not Developmental Units But Emerge from Physical Cracking.  Milinkovitch et al.   
 
One of a crocodile’s most characteristic traits is its thick, scaly skin. Although similar in appearance to elaborately patterned skin of other reptiles, the scales on...
Biological05/30/2014 Can DNA Enhance Your Look?
Fine Tuning of Craniofacial Morphology by Distant-Acting Enhancers.  Attanasio et al.   
 
We’re all familiar the adage that no two faces are alike. But, how is this tremendous amount of variation possible? Using genetic tools and three-dimensional imaging, this paper makes the...
Physical04/25/2014 Quake, Rattle, and Roll
Enhanced Remote Earthquake Triggering at Fluid-Injection Sites in the Midwestern United States.  van der Elst et al.
 
One predictable feature of earthquakes is that they are completely unpredictable.  Or are they?  Scientists are beginning to collect data indicating that a range of human activity, including hydraulic fracturing, can induce earthquakes.  How...
Physical03/28/2014 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, have an...
Biological02/28/2014 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 person?  To...
