With most of Puerto Rico in the dark Wednesday night, Gov. Ricardo Rossello said in a tweet that he has suggested Puerto Rico's Electric Power Authority cancel its contract with a subcontractor that caused an island-wide power outage.

An excavator operated by D. Grimm, a subcontractor for Cobra Acquisitions, apparently caused the blackout, which originated at a major transmission line running between Salinas and Guayama in the southeast, according to the authority . . .

 . . . As of 8 p.m., only 334,000 customers in the US commonwealth had electricity again. Power was to be restored to customers who had electricity before the latest outage within 24 to 36 hours, the authority said.

HEAT ISLANDS  Heat claims more lives than floods, hurricanes and other weather-related disasters. How will cities cope as temperatures rise?  ULTRAFORMA/ISTOCKPHOTO

When days and nights get too hot, city dwellers are the first to run into trouble

Since 1986, the first year the National Weather Service reported data on heat-related deaths, more people in the United States have died from heat (3,979) than from any other weather-related disaster — more than floods (2,599), tornadoes (2,116) or hurricanes (1,391). Heat’s victim counts would be even higher, but unless the deceased are found with a fatal body temperature or in a hot room, the fact that heat might have been the cause is often left off of the death certificate, says Jonathan Patz, director of the Global Health Institute at the University of Wisconsin–Madison.

As greenhouse gases accumulate in the atmosphere, heat’s toll is expected to rise. Temperatures will probably keep smashing records as carbon dioxide, methane and other gases continue warming the planet. Heat waves (unusually hot weather lasting two or more days) will probably be longer, hotter and more frequent in the future.

The growth of urban settlements is subject to a range of factors influenced by demographic, economic, political, environmental, cultural, and social factors. Weather variability, or climate change, has recently risen up this list. These two factors: climate change and urban population growth, are dramatically affecting urban water management. On one hand, growing populations increase urban water demand and on the other, climate change has increased water variability (volume, distribution, timing and quality) . . .

Abstract

BACKGROUND

The risk of congenital neurologic defects related to Zika virus (ZIKV) infection has ranged from 6 to 42% in various reports. The aim of this study was to estimate this risk among pregnant women with symptomatic ZIKV infection in French territories in the Americas.

METHODS

From March 2016 through November 2016, we enrolled in this prospective cohort study pregnant women with symptomatic ZIKV infection that was confirmed by polymerase-chain-reaction (PCR) assay. The analysis included all data collected up to April 27, 2017, the date of the last delivery in the cohort.
