Houston’s Poor Neighborhoods Could Be Prime Zika Real Estate
The World Health Organization (WHO) has warned of the potential for the explosive spread of the Zika virus through the Americas. Margaret Chan, the director of the WHO, advised that the Americas could be hit by 4 million cases of Zika this year. The outbreak of Zika virus now centered in Brazil has been linked to a sudden increase in severe birth defects including microcephaly, babies born with smaller heads and brains. The National Public Radio – USA (NPR) recently reported that other neurological problems, such as babies born blind, may also be linked to Zika. Researchers do not fully understand Zika or have not yet proven causality, but the circumstantial evidence connecting the Zika outbreak to the sudden, large increase in birth defects is very strong.
Reports quoted experts who said that Zika was a low risk to the United States because the U.S. doesn’t have the poverty and high population densities that have caused the explosive spread of Zika in Brazil. However, Dr. Peter Hotez, a tropical disease researcher who lives in Texas, has warned that poverty and high population density makes Houston highly vulnerable to a Zika outbreak. He warned that the whole Mexican Gulf coast is already suffering from increasing levels of tropical diseases spread by mosquitoes, in particular dengue fever. Because Zika virus is related to dengue fever and has the same mosquito vector, the expansion of dengue in the Gulf coast region is a good indicator of the potential spread of Zika virus.

A new planet in our neighborhood - how likely is life there?
By Don Lincoln, August 24, 2016
Scientists working at the European Southern Observatory (ESO), using the La Silla telescope, claim to have discovered the closest exoplanet to Earth. Exoplanet means planets orbiting stars other than the Sun. Most of them are huge planets orbiting very near their star. The newly discovered planet, which orbits Proxima Centauri, a star within the so-called “habitable zone”, has been named Proxima b.
Proxima Centauri is a red dwarf, which is the most common type of star in the galaxy. Red dwarfs are much smaller than our Sun, and are very dim. For instance, in the visible spectrum that we use to see, Proxima Centauri gives off 0.0056% as much light as the Sun.
So what about life? Are there any chances that an alien lizard might bask in Proxima Centauri’s light or try to find shade under an alien tree? Dr. Guillem Anglada-Escudé, co-author of the research from London University, believes that “there is a reasonable expectation that this planet might be able to host life”
But this belief is not consensual as other scientists think the prospect of life is improbable. Although the temperature of the planet is thought to be such that liquid water could exist, it is unlikely that Proxima b is habitable, as the planet is subject to stellar wind pressures of more than 2000 times those experienced by Earth from the solar wind. These winds would likely blow any atmosphere away, leaving the undersurface as the only vaguely habitable location on that planet. You shouldn’t imagine, thus, a lush and verdant world, with lovely blue waters, sandy beaches and green plants.
So, what’s the bottom line? First, the discovery is extremely exciting. The existence of a nearby planet in the habitable zone will perhaps increase the interest in efforts like Project Starshot, which aims to send microprobes (instruments that apply a stable and wellfocused beam of charged particles -electrons or ions- to a sample) to Proxima Centauri. On the other hand, Proxima b is unlikely to be a haven for people trying to escape the ecological issues of Earth, so we should not view this discovery as a way to ignore our own ecosystem.
