Looking up on Down Syndrome. Trying to find the cause behind genetic anomalies

Dr. Sara Frías Vázquez of UNAM’s Biomedical Research Institute studies the causes behind the birth of children with Down syndrome. According to her research, more than 60% of kids that are diagnosed with the syndrome have mothers younger than 40 years old. Even though the risk of conceiving a child with Down syndrome is greater in women that have surpassed their reproductive age, there is a greater number of young mothers because they reproduce more. Down syndrome is the result of an extra copy of the 21st chromosome, that is, one of the structures that carry the genetic information of each indi vidual. This disruption is characterized by particular physical traits and a variable degree of d

Stir it up! Sea Monkeys Mix the Ocean.

As large and vast as the ocean may seem, some of the smallest creatures living in it have an enormous effect on it. Monica Martinez, Fluid Mechanics Engineer from UNAM and Ph.D. candidate at Caltech, is researching how small creatures such as krill and plankton can mix and transport nutrients in the ocean over great distances affecting the overall composition of seawater. The experiment aims to assess how small creatures like these ones can have a substantial effect on currents, temperature and other factors of the seawater. Martinez uses brine shrimp, also known as Sea Monkeys, because krill and plankton are very hard to keep alive in the lab. With the use of a laser, Monica makes the shrim
