CLICK HERE - STUDY - Environment International - Prenatal naled and chlorpyrifos exposure is associated with deficits in infant motor function in a cohort of Chinese infants

Naled -- the main chemical ingredient in the bug spray used in Miami to ward off Zika-carrying mosquitoes -- has an association with reduced motor function in infants, according to a study published Thursday in the journal Environmental International.

The University of Michigan researchers found that children in China who had the highest prenatal exposure to naled had, at age 9 months, 3% to 4% lower scores on tests of their fine motor skills, which are the small movements of hands, fingers, face, mouth and feet, compared with those with the lowest exposure.

This is the first general-population study of the insecticide chemical, the researchers said.

nytimes.com - by Coral Davenport and Eric Lipton - June 3, 2017

The Republican Party’s fast journey from debating how to combat human-caused climate change to arguing that it does not exist is a story of big political money, Democratic hubris in the Obama years and a partisan chasm that grew over nine years like a crack in the Antarctic shelf, favoring extreme positions and uncompromising rhetoric over cooperation and conciliation . . .

<In 2008 Senator John McCain, who had just secured the Republican nomination for President, sounded the alarm on global warming.>

 . . . Since Mr. McCain ran for president on climate credentials that were stronger than his opponent Barack Obama’s, the scientific evidence linking greenhouse gases from fossil fuels to the dangerous warming of the planet has grown stronger.

A new quarterly report from the folks who brought you '50 States of Solar' aims to chronicle grid modernization initiatives across the US

utilitydive.com - by Herman K. Trabish - May 31, 2017

Grid modernization is a hot topic in the power sector as utilities across the country replace aging infrastructure and upgrade their systems for new energy technologies.

But until now, there was no easily-accessible tool to track the myriad regulatory actions on advanced metering, non-wire alternatives, ratemaking reform and the like.

washingtonpost.com - Associated Press - May 27, 2017

 . . . In an attempt to understand what could happen to the planet if the U.S. pulls out of Paris, The Associated Press consulted with more than two dozen climate scientists and analyzed a special computer model scenario designed to calculate potential effects.

Scientists said it would worsen an already bad problem, and make it far more difficult to prevent crossing a dangerous global temperature threshold.

 . . . “The U.S. matters a great deal . . . That amount could make the difference between meeting the Paris limit of two degrees and missing it” . . . 

While scientists may disagree on the computer simulations they overwhelmingly agreed that the warming the planet is undergoing now would be faster and more intense.

npr.org - by Greg Allen - May 24, 2017

Last year's Zika outbreak in Miami likely started in the spring of 2016, with the virus introduced multiple times before it was detected, researchers say. And most of those cases originated in the Caribbean.

The study, published Wednesday in Nature, examined more than 250 cases of local Zika transmission in three Miami neighborhoods. Researchers analyzed 39 Zika virus genomes isolated from 32 people who had been infected and seven Aedes aegypti mosquitoes, the species that carries Zika.

Comparison of differences in those genomes finds the virus was introduced by travelers at least four and perhaps as many as 40 different times as early as March 2016. Local transmission of Zika wasn't confirmed in Miami until late July.

A new scientific analysis finds that the Earth’s oceans are rising nearly three times as rapidly as they were throughout most of the 20th century, one of the strongest indications yet that a much feared trend of not just sea level rise, but its acceleration, is now underway.

“We have a much stronger acceleration in sea level rise than formerly thought,” said Sönke Dangendorf, a researcher with the University of Siegen in Germany who led the study along with scientists at institutions in Spain, France, Norway and the Netherlands.

New Zika Virus Inhibitor Identified

CLICK HERE - RESEARCH - Characterization of the Zika virus two-component NS2B-NS3 protease and structure-assisted identification of allosteric small-molecule antagonists

business-standard.com - ANI - May 17, 2017

A new research has brought a drug to treat Zika infections closer to reality.

The team led by Alexey Terskikh and Alex Strongin from Sanford Burnham Prebys Medical Discovery Institute (SBP) discovered a compound that prevents the virus from spreading.

"We identified a small molecule that inhibits the Zika virus protease, and show that it blocks viral propagation in human cells and in mice," Terskikh said. "Anti-Zika drugs are desperately needed. The fact that the compound seems to work in vivo is really promising, so we plan to use it as a starting point to make an even more potent and effective drug."

Are Solar and Wind Really Killing Coal, Nuclear and Grid Reliability?

           

Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets. Sarah Fields Photography/Shutterstock.com

theconversation.com - by Joshua D. Rhodes, Michael E. Webber, Thomas Deetjen and Todd Davidson - May 11, 2017

U.S. Secretary of Energy Rick Perry in April requested a study to assess the effect of renewable energy policies on nuclear and coal-fired power plants.

Some energy analysts responded with confusion, as the subject has been extensively studied by grid operators and the Department of Energy’s own national labs. Others were more critical, saying the intent of the review is to favor the use of nuclear and coal over renewable sources.

So, are wind and solar killing coal and nuclear? Yes, but not by themselves and not for the reasons most people think. Are wind and solar killing grid reliability? No, not where the grid’s technology and regulations have been modernized. In those places, overall grid operation has improved, not worsened.

climate.gov - by Adam B. Smith - January 9, 2017

NOAA’s National Centers for Environmental Information (NCEI) tracks U.S. weather and climate events that have great economic and societal impacts (www.ncdc.noaa.gov/billions). Since 1980, the U.S. has sustained 203 weather and climate disasters where the overall damage costs reached or exceeded $1 billion (including adjustments based on the Consumer Price Index, as of January 2017). The cumulative costs for these 203 events exceed $1.1 trillion.

The Zika virus stands to cost the United States billions of dollars, even if few people are infected.

Researchers from several American institutions have calculated that the "virus from Hell" could result in total costs ranging from $183 million to over $1.2 billion, depending on infection rates in several at-risk states in the South.

The researchers warn that infection rates could engender costs that exceed the amounts of money the U.S. government may give for prevention and treatment, if the recent debates over funding are any indication.

statnews.com - by Helen Branswell - May 5, 2017

 . . . Testing for Zika infection is becoming more difficult, making it harder for doctors to advise pregnant women about the chances their child might have a Zika-related birth defect, the Centers for Disease Control and Prevention revealed in a health advisory issued Friday.

The CDC is now suggesting that women thinking of getting pregnant, and who may be exposed to the Zika virus through travel or because of where they live, should consider having their blood tested for Zika antibodies before they get pregnant. Having a baseline reading would help to interpret Zika tests done during a later pregnancy.

CLICK HERE - PLOS - Detecting the impact of temperature on transmission of Zika, dengue, and chikungunya using mechanistic models

futurity.org - Stanford University - May 5, 2017

New research shows how rising temperatures might influence mosquito behavior and disease risk around the world. The researchers also calibrated their model with field data on human infections of mosquito-borne diseases.

Scientists have known for some time that climate change has caused the extension of mosquito season beyond the summer months, but the ways in which climate change affects the risk of mosquito-borne diseases such as dengue, chikungunya, and Zika has remained somewhat mysterious . . .

 . . . The group found that mosquito traits favorable to spreading disease peaked when temperatures reached 29 degrees Celsius (84 degrees Fahrenheit), but were lower when temperatures were cooler or warmer.

Echocardiography evaluation of a group of Brazilian babies with Zika-related birth defects found three times the expected rate of congenital heart disease (CHD), but only one infant had symptoms and most had minor septal defects that weren't hemodynamically significant.

The study is the first time CHD has been assessed in infants with congenital Zika infections, and so far there haven't been any reports of autopsy findings suggesting a connection, but other flaviviruses such as dengue have been associated with myocarditis and pericarditis.

Climate change is altering the environment in ways that increase the potential for viruses like Zika.

nytimes.com - by Maryn McKenna - April 20, 2017

 . . . Climate change is turning abnormal weather into a common occurrence: Last year was the warmest year on record, the third in a row, and there were more heat waves, freezes and storms in the United States that caused $1 billion or more in damage just in 2016 than in the years 1980 to 1984 combined. Anything that improves conditions for mosquitoes tips the scales for the diseases they carry as well: the West Nile virus that flattened Dallas, the dengue that returned to Florida in 2009 after 63 years and the newest arrival, Zika, which gained a toehold in the United States last year and is expected to surge this summer . . .
