Sensitization after an Injury Increases Survival

Sensitization after an Injury Increases Survival

Researchers at the University of Texas Medical School released the first piece of concrete evidence that nociceptive sensitization results in an adaptive advantage. Using squid (Doryteuthis pealeii)as their test organism, the scientists demonstrated that both behavioral and neurological changes resulting from noxious stimuli, like a minor injury, increase the likelihood...

 
 

Transmission of Trauma by Sperm RNA

Transmission of Trauma by Sperm RNA

  The effects of trauma can be passed down through generations, resulting in psychiatric disorders like depression in offspring. Researchers have found small non-coding RNAs (sncRNAs), molecules that could be the link between environmental factors, like trauma, and genes (1). Both genetic make-up and environmental factors serve as important contributors...

 
 

Why the Zebra Has Stripes

Why the Zebra Has Stripes

Scientists from University of California, Davis systematically examined the function of zebra stripes. From their analyses, many long-standing, but previously unconfirmed hypotheses were rejected, and it is now believed that zebra stripes serve to avoid biting flies. Prior to this research, there were five main functional hypotheses for the adaptation...

 
 

Regenerative Muscle Engineered

Regenerative Muscle Engineered

Biomedical engineers have managed to create a lab-grown skeletal muscle that behaves like the genuine tissue. It is capable of contraction, can be integrated naturally into mice, and demonstrates the power to heal itself. (1) “The muscle we have made represents an important advance for the field. It’s the first...
