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 Edmund Halley 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).

The Science Behind Earthquakes

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.

Sea cucumbers and regeneration

Sea cucumbers are echinoderms commonly found in the coasts of Puerto Rico. Although they are called ìcucumbersî due to their morphology, they are not really plants, but animals. In Asia they are considered a delicacy, but in Puerto Rico they are not used as food. Instead, they are used by researchers to understand one of the biggest mysteries in biology: the process of regeneration. Certain organisms, like echinoderms, have regenerative capacities, and can grow new organs from scratch even as adults. Other organisms, such as mammals, have very limited regenerative capacities.

Supernovas and X-Rays

When we look at the sky during the night it is possible to appreciate stars of different colors and brightnesses. However, although we may think that stars will bright forever, the stars, as all the existence on the Earth and space, also have their life-cycle. There’s a type of stars called the supergiants that emit lots of luminosity. When a supergiant star collapse with itself in a way that they can produce an explosion, it produces what is known as supernova. A supernova is the process that occurs when a star’s life-cycle ends and explodes. In this process, the supernova explosion may produce a huge amount of energy similar to the one emitted by the Sun that is also a star.

Metagenomics of the Puerto Rican Soil

Although we are in a constant war to get rid of them, we have always lived in a world dominated by microbes. Interestingly, there is a new science field that aims to reveal the secrets of the microbial planet, but not as a tactic of war. Even though we donít pay a lot of attention to our microscopic friends, the microbial communities support all life of Earth, even ours. For this cause, understanding the characteristics of this unexplored microbial world may help us to solve many of the environmental, medical, biotechnological, energetical, and economical challenges of the world. The name of this new science is Metagenomics.

Development of the Neuronal Circuit

Did you know that in average humans have approximately 100 billion neurons in the brain? Neurons are cells of the nervous system that respond to electric stimulus and process and transmit information. If you though that neurons only reside in the brain, you are wrong because they are found also in the spinal cord and the peripheral nerves. The complex area of science that study neurons, their development and pathology is neuroscience.

Genomas: Personalized Medicine

Overview of Genoma's PhyzioType System

Did you know that most of the prescribed or over the counter drugs have adverse reactions that we donít even know? The problem is that all the drugs that go out in the market, although tested in clinical trials, are studied in a representative sample of a population that probably will not represent what will happen to you. Most of the time when they go out to the market they present adverse reactions not reflected in the clinical trials. Then, what we should do? How we can predict if a drug that is supposed to cure me will kill me eventually? Thanks to Genomas and Dr. Gualberto Ruaño research, nowadays this is possible.

"Proteomics", Mass Spectrometry and Puerto Rico

We know that you are asking yourself what these three words from the title have in common: Proteomics, Mass Spectrometry and Puerto Rico. However, if we analyze them closely you will figure out. Beginning with proteomics, the word in Spanish is a bit difficult to pronounce: proteomica. Proteomics is the science field that studies proteins and their structure and function. And what does "Mass Spectrometry" have to do in this? WellÖ a lot because mass spectrometry (MS) is one of the analysis techniques used to determine the mass, identity and modification of proteins. And for those that are wondering what is Puerto Rico's role in all this; please blame Dr. Irving E.

Corazón Hispano: protecting cardiovascular health in vulnerable Hispanic populations

Heart disease is the main cause of death in Puerto Rico and Latin America. According to the American Heart Association, every 35 seconds somebody dies due to complications regarding cardiovascular disorders.

The heart is responsible for pumping blood to all tissues. In spite of its strength, the heart is a delicate organ, susceptible to environmental risk factors.
