Frequently, science teachers ask their students to draw a scientist so that they can get a sense of what students think and imagine about scientists. Thousands and thousands of drawings show the same stereotypical characteristics: a male scientist, white, dressed in a lab coat, usually a chemist mixing liquids and generating explosions, and a person that does not have any physical limitations. 

No student has ever drawn a scientist like Dr. Wanda Díaz Merced.  This young woman from Gurabo embodies the scientific anti-stereotype. Not only is she a woman and Puerto Rican, but also she completed her doctoral work in astrophysics, and without being able to use her sight.

This October 2013 science commemorates the 20th anniversary of Joseph Taylor and Russell Hulse’s Nobel Prize in Physics for the discovery of the first binary neutron star. The scientists used the Arecibo Radiotelescope to collect their historical data, back in the 1970s.

When technology jumps the gun

Submitted by Wilson Gonzalez-Espada on

The pages of history are full of cases when a new scientific discovery is commercialized without fully understanding the side effects or health risks involved. Examples such as x-rays, París green, radioactive materials, nanotubes, and genetically-modified crops must be carefully examined so that we can learn how to avoid deadly technologies.

Puerto Rican students excel in scientific research

The earliest school students get involved in authentic scientific research, the more likely it is for them to stay interested in the science. Michelle Pérez, Jessica Ríos and Netsha Santiago, three high school students, successfully completed a summer research experience as part of a partnership between the National Science Foundation, Universidad Metropolitana, and several universities in the United States.

Cuba risks losing a vast stretch of beach front homes and pristine coastal habitat by 2050, because of rapidly rising sea levels, a top environmental official warned Thursday. 

At a panel discussion on Cuban environmental policy, Tomas Escobar, director of the island's National Environment Agency, said rising oceans could submerge huge areas of the Caribbean island, with potentially devastating consequences.

Environmental officials and scientists warned Friday that Puerto Rico is dangerously vulnerable to the effects of global climate change and urged it to prepare by better-regulated coastal development, and perhaps even by building artificial reefs. 

The storm-caused floods and erosion that have always affected the U.S. Caribbean territory are expected to grow worse as temperatures and seas rise, perhaps by 22 inches (57 centimeters) by 2060, according to a U.S. Army Corps of Engineers study.
