RUM scientists investigate asbestos levels in serpentinite

This article is reproduced by CienciaPR with permission from the original source.

Scientists of the University of Puerto Rico in Mayagüez are studying the serpentinite, a kind of metamorphic rock (meaning that it’s altered by drastic temperature and pressure changes) existent in Puerto Rican soil, specially in the southwest. This rock contains small amounts of chrysotile asbestos and the purpose of this study is to determine in what amounts is asbestos present in Puerto Rico’s serpetinite, because if it turns out positive it would be necessary to regulate its use and extraction. In Puerto Rico, this rock is mainly used for concrete. It’s also used sometimes as a filler for roads or in the construction of houses. Asbestos can produce two kinds of lesions in humans: pulmonary asbestosis, a thickening of the alveoli in the lungs or its pleura, and lung or larynx cancer, including mesothelioma, the most malignant of work-related tumors.

Scientists urge environmental action

For the second time in a week, a group of renowned scientists approved a series of recommendations for the Government to address the local effects of global warming. This time, it was 20 experts of different fields in the environmental sciences, invited by the University of Puerto Rico in Mayaguez. The recommendations stem from two-day round table meetings “Facing the consequences of global warming in Puerto Rico”. The scientists urge the Government to: 1. Acknowledge the global warming problem. 2. Create a Commission that will prepare, before the term ends, the mitigation and adaptation to global warming strategy. 3. That every project is evaluated on its contribution to climate change and to stop permits for construction in high risk zones. 4. Encourage the reconstruction of urban centers, facilitate collective, alternative and non-automotive transportation and stop urban overflow. 5. Redefine the maritime-land zones in terms of public and environmental safety. 6. Protect 25% of the land. 7. 50% of forests and 25% of the insular platform banned from fishing. 8. Conserve and keep the agricultural potential of lands. 9. Encourage the conversion of public buildings into green buildings. 10. Reduce the energy use in all government agencies by 20% in a five year period. 11. Buy hybrid cars for the State’s fleet. 12. Encourage the purchase of high performance equipment.

Puerto Rican with a foreign name

The Puerto Rican Tody (Todus mexicanus) is a little endemic bird of Puerto Rico with green feathers, a red beak and red neck that feeds on a great diversity of insects (like flies, dragonflies and crickets) but can also eat small lizards and fruits. Our Puerto Rican Tody is part of the Todidae bird family that can only be found in the Greater Antilles.

Neuroscience is the study of the nervous system, which includes the brain, the spinal cord and the networks of sensory neurons throughout our body. It’s a multidisciplinary science that integrates biology, chemistry, and physics with the study of the nervous system’s structure, its physiology, behavior, emotions and cognitive functions. There are scientists that study the development of the nervous; neuroanatomists study its structure and organization. Some study cognitive processes, like visual perception and memory and others study processes underlying behavior. Other neuroscientists study the computational aspects of the brain. Some dedicate to study the clinical aspect of neuroscience, investigating the causes, effects and possible treatments for diseases like Parkinson, Alzheimer and schizophrenia, among many others. Meanwhile, molecular neuroscientists see the brain as a group of neurons that are composed of genes, proteins and molecules, vital for neuronal function. Puerto Rico has a large variety of these scientists. Our Island has a rich neuroscience community, having an Institute of Neurobiology in Old San Juan, next to El Morro. Also, the Schools of Medicine in Ponce, the University of Puerto Rico and the Universidad Central del Caribe; and the University of Puerto Rico in Mayaguez and Rio Piedras are home to Puerto Rico’s neuroscientists. *This article is part of CienciaPR's collaboration with El Nuevo Dia

Pharmaceutical Baxter celebrated a clinical educational meeting titled “Avian flu and influenza: possible impact in Puerto Rico”. Although avian flu is still an avian disease concentrated in Asia, Puerto Rico must prepare for the eventuality that it turns into an epidemic disease in the near future.

Children raise their voice in pro of the environment

While most of the Puerto Rican scientific community demands the government to start taking initiatives to reduce the effects of global warming, hundreds of children in Guayanilla, which are part of the generation that could probable suffer the most of these effects, march through the town center of this municipality to drive a message of environmental protection and recycling.

Six products to save water

The Water and Sewage Authority has created a “savings kit” to invite the Puerto Rican consumer to optimize the usage of potable water and save money. These six products can be placed in the toilet, water hose, the shower, the kitchen sink and the bathroom sink, and can be found in hardware stores at a price of $2 to $3 a piece. “Using them could represent a $10 to $15 savings in the monthly water bill. The invitation is to recuperate the $12 investment in about a month and then keep saving.” The products are the following: water flow optimizers for the shower, the kitchen sink and the bathroom sink; a nozzle for the water hose; a water volume reducing bag for the toilet’s water tank; and a tablet to detect leaks in the toilet’s water tank.

Perpetual protection

The Taller de Arte y Cultura de Adjuntas (Arts and Culture Workshop of Adjuntas), better known as Casa Pueblo (Town House), gave legal character to its efforts with the creation of the Casa Pueblo Trust. With this document they want to protect the continuity of the assets of this community based organization, among them 150 acres of the La Olimpia School Forest, acquired in part with money raised with the sales of Coffee Mother Island, made by volunteers of this non-profit organization. Besides the Forest and Coffee Mother Island, Casa Pueblo has educational workshops, like the Biodiversity and Culture Community Institute; it has hydroponics lettuce crop; a butterfly garden and a library.

No protection against hurricanes

Geomorphologist José Molinelli said that Puerto Rico’s infrastructure is not ready for the devastating hurricanes that are being forecasted to be more and more common with climate change. Molinelli also said that although it is forecasted that global warming will bring less rain to countries like Puerto Rico, when it does rain, the tendency will be towards torrential rain which will cause more flooding problems than today. This situation impacts the economy and requires a longer recuperation time, besides requiring a revision of construction codes.

Urgent call to do something about global warming in Puerto Rico

This article is reproduced by CienciaPR with permission from the original source.

A large group of scientists and academics of Puerto Rico claimed the government to incorporate the information available about climate change in the urban planning procedures to avoid future disasters and reduce the local effects of global warming. The claimed was made in a formal declaration signed by 174 experts that demand that the Land Use Plan and other planning procedures take into account the projected effects of climate change, among them, an increase in the sea level, coastal flooding and erosion, salinization of aquifers and a reduction in pluvial precipitation. The document was presented in a press conference by Félix Aponte, geomorphologist José Molinelli, marine ecologist Edwin Hernández Delgado, herpetologists Rafael Joglar and Patricia Burrowes, chemist Ricardo Morales and environmental activist Luis Jorge Rivera Herrera, among others.
