CienciaPR website throughout time. March, 2006 (left). Right, August, 2011
CienciaPR.org was established in 2006 with the mission of providing a site in where the members of the scattered Puerto Rican scientific community could have a meeting point. Thanks to the support of thousands of users and a dedicated group of volunteer scientists, in five years, CienciaPR have exceeded the initial expectations becoming one of the scientific portals of more coverage in Puerto Rico and Latin America.
Simposio de CienciaPR: Quiero ser científico… ¿y ahora qué hago?
Understanding the world around them. This is what motivates thousands of people, in Puerto Rico and around the world, to do science. The great patriot and educator Eugenio María de Hostosonce said: "Science is the presentation of each and every one of the efforts of understanding."
Through history, science has been a key element in one of the most fundamental quests of humanity: the generation of knowledge to understand the world around us. It could be said that science makes us humans. After all, scientific questions stem from curiosity, a quality we all share.

Archeological findings help reveal the secrets of old civilizations, construct the history of a place and its ancestors, and shape the identity of contemporary people. The knowledge of our Puerto Rican history, more than an agglomeration of findings that reveal an unknown origin, was a life style for Dr. Ricardo Alegría-Gallardowhom we honor with this spotlight.
Our society is at the cusp of a scientific revolution. The generation and application of knowledge and innovation have fundamentally changed the way we live and are a driving force in the global economy. For that reason many countries around the world, including Puerto Rico, are making a push to establish knowledge-based economies.
The Gas Pipeline will impact several acres of rivers, forests and residential areas.
For some time, in Puerto Rico we have been hearing about the Gas Pipeline project or the Green Way. Since CienciaPR¥s mission is to impartially educate the general public, we have prepared this small special story a about what is in reality the Gas Pipeline and what are the possible advantages and risks associated with the construction, management and maintenance of it.
When the different NASA spacecraft such as Voyager, Mars Reconnaissance Orbiter (MRO), Lunar Reconnaissance Orbiter (LRO), and MESSENGER (Mercury Surface, Space Environment, Geochemistry and Ranging), among others, currently exploring the universe send messages to Earth, they do so through the transmission of microwaves, a type of electromagnetic wave, shorter in wavelength than that of radio, that can travel far distances and penetrate through the atmosphere. While longer microwaves are used to cook our food, shorter microwaves are used for satellite communication to Earth, for radar systems such as the Doppler weather radar, for GPS navigation, and even for wireless internet signals.
mtDNA can be classified in haplogroups which are specific for differents regions in the world. This figure shows the haplogroup A of PR.
Do you remember the stories about the native inhabitants of Puerto Rico that we were taught in school? Yes, the Taino Indians. They faded with the arrival of Spanish colonizers, according to the story. When exactly TaÌno ceased to exist? There is archaeological evidence indicating that the Tainos lived on the island longer than historians point, but there are still conflicting versions of both lines. Not only archaeologists and historians were interested in learning more about the Taino culture. A curious scientist that since he was a teenager was fascinated with stories about the Tainos, had in mind a number of questions, but mostly an effort to answer them.

The study of the planets, the stars, and the universe, in which we live, is the passion of many scientists.. Since the times of the British astronomer EdmundHalley and the British physicist Isaac Newton, the study field of Astronomy has been essential to understand what distinguishes celestial objects (position, distribution, movement, composition and energy).
Throughout human history, all generations looked to the sky and asked: What exists beyond our World? That same curiosity awoke in the Uruguayan scientist and member of CienciaPR,Dr. Daniel Altschuler the interest in investigate the galaxies.
Two months ago we received 2010 with the news that neighboring Haiti was struck with a 7.0 magnitude earthquake. Not recovered from Haiti’s situation, in the last days of February, Chile also experiences an earthquake; this time an 8.8 one and nowadays they are still getting aftershocks. After all these events have you ever asked yourself what causes an earthquake? Can Puerto Rico be struck by an earthquake? Fortunately, the answers to all these questions and the science behind earthquakes are the focus of the research of geologists like Dr. Daniel Laó Dávila and the Puerto Rico Seismic Network.
