Electric car purchases have been on the rise lately, posting an estimated 60 percent growth rate last year. They’re poised for rapid adoption by 2022, when EVs are projected to cost the same as internal combustion cars. However, these estimates all presume the incumbent lithium-ion battery remains the go-to EV power source. So, when researchers this week at the University of Texas at Austin unveiled a new, promising lithium- or sodium-glass battery technology, it threatened to accelerate even rosy projections for battery-powered cars.

LA JOLLA, California — The Zika virus outbreak in the United States in 2016 was caused by multiple infected travelers arriving in South Florida, not by a single "patient zero," genomic research has revealed.

Reporting here at the 10th Future of Genomic Medicine Conference, Kristian Andersen, PhD, from Scripps Translational Science Institute in La Jolla, California, and his team identified four different "introductions" of the Zika virus during the outbreak using genomic sequencing by testing samples from 17 people.

Extrapolating this to the total number of infected people, "the number of introductions that caused the outbreak in Miami is quite substantial," maybe on the order of 30, he explained.

Genomic sequencing of the virus from mosquitos and patients also revealed that Caribbean travelers were the primary means of introduction.

How California Utilities Are Managing Excess Solar Power

news.morningstar.com - by Cassandra Sweet - March 4, 2017

California utilities including PG&E Corp., Edison International and Sempra Energy are testing new ways to network solar panels, battery storage, two-way communication devices and software to create "virtual power plants" that manage green power and feed it into the power grid as needed.

The Golden State is ramping up renewable energy as it pledges to be a bulwark against the Trump administration's pro-fossil fuel policies. But first, it has to figure out what to do with all the excess power it generates when the sun is shining and the wind is blowing.

American mothers infected with the Zika virus last year were 20 times as likely to give birth to babies with birth defects as mothers who gave birth two years before the epidemic, federal health officials said on Thursday.

The Centers for Disease Control and Prevention concluded last April that Zika infection caused severe birth defects, including the abnormally small heads of microcephaly, but it had not previously estimated how common such defects were.

The findings are key to unraveling the mysteries of why the Zika virus causes birth defects

CLICK HERE - Stem Cell Reports - Differential Responses of Human Fetal Brain Neural Stem Cells to Zika Virus Infection

GALVESTON, Texas –A multidisciplinary team from The University of Texas Medical Branch at Galveston has uncovered the mechanisms that the Zika virus uses to alter brain development. These findings are detailed in Stem Cell Reports . . .

. . . Since a normal brain develops from simple cells called stem cells that are able to develop into any one of various kinds of cells, the UTMB team deduced that microcephaly is most likely linked with abnormal function of these cells . . .

. . . The researchers established a method of investigating how Zika alters the production, survival and maturation of brain stem cells using cells donated from three human fetal brains. They focused on the impact of the Asian lineage Zika virus that was involved in the first outbreak in North America in late 2015.

scientificamerican.com - by Kavya Balaraman - December 21, 2016

Mosquito-borne diseases like Zika can be extremely sensitive to climatic changes

The combination of climate change and last year’s El Niño phenomenon likely created the perfect playground for the Zika virus to spread rapidly across South America, a new study finds.

Both the Zika virus and the mosquitoes that carry it have been present in different parts of the world for a while. But several factors, including specific climatic conditions, could have catapulted the disease to public health emergency status, according to researchers from the University of Liverpool.

Birth Defects Among Fetuses and Infants of US Women With Evidence of Possible Zika Virus Infection During Pregnancy

jamanetwork.com - December 13, 2016 - doi:10.1001/jama.2016.19006

In this report based on preliminary data for pregnant women in the USZPR with laboratory evidence of possible Zika virus infection, 6% overall had a fetus or infant with evidence of a Zika-related birth defect, and among women with timing of possible Zika infection exclusively during the first trimester, 11% had a fetus or infant with a birth defect. The birth defects primarily involved included microcephaly with brain abnormalities, such as intracranial calcifications. Preliminary estimates from the USZPR were within the range of 1% to 13% risk of microcephaly following first-trimester maternal Zika virus infection modeled on the outbreak in Bahia, Brazil, lending support to the credibility of these estimates.

Negative Effects Of Zika During Pregnancy More Common Than Realized

           

Juan Pedro, who has microcephaly and turned one-year-old on December 4, sits in a specially designed chair to keep him upright as he is kissed by his sister Jennifer Karine on December 12, 2016 in Recife, Brazil. As many of the babies with microcephaly, believed to be linked to the Zika virus, turn one-year-old in Recife, doctors and mothers are adapting and learning treatments to assist and calm the children. Many of the children are suffering a plethora of difficulties including vision and hearing problems with doctors now labeling the overall condition as 'Congenital Zika Syndrome'.

Colombia Reports Major Rise in Birth Defect Amid Zika Crisis

CLICK HERE - CDC - MMWR - Preliminary Report of Microcephaly Potentially Associated with Zika Virus Infection During Pregnancy — Colombia, January–November 2016

nytimes.com - by Donald G. McNeil, Jr. - December 10, 2016

Colombia, which suffered a Zika epidemic that peaked in February, has reported four times as many cases of babies born with microcephaly this year as it did in 2015, providing more proof that the Zika virus causes brain damage in infants.

Because births of microcephalic infants peaked five months after the epidemic did, at about nine times the numbers of the previous July, scientists feel sure that the greatest risk is to babies whose mothers were infected during their first trimesters or early in their second.

The numbers were reported in a study released Friday by the Centers for Disease Control and Prevention and conducted jointly by scientists from the C.D.C. and Colombia’s national health institute.

Working in the lab, UC San Francisco researchers have identified fetal brain tissue cells that are targeted by the Zika virus and determined that azithromycin, a common antibiotic regarded as safe for use during pregnancy, can prevent the virus from infecting these cells . . .

 . . . In the new study, published online Nov. 29, 2016, in the Proceedings of the National Academy of Sciences (PNAS), the UCSF researchers determined that the Zika virus preferentially infects brain cells with an abundance of a protein called AXL, which spans the outer cell membrane of several cell types and serves as a gateway for the invading virus . . .

nytimes.com - by Pam Belluck - November 22, 2016

It is the news that doctors and families in the heart of Zika territory had feared: Some babies not born with the unusually small heads that are the most severe hallmark of brain damage as a result of the virus have developed the condition, called microcephaly, as they have grown older.

The findings were reported in a study of 13 babies in Brazil that was published Tuesday in Morbidity and Mortality Weekly Report. At birth, none of the babies had heads small enough to receive a diagnosis of microcephaly, but months later, 11 of them did . . . 

 . . . The new study echoes another published this fall, in which three babies were found to have microcephaly later in their first year.

sciencedaily.com - American Association of Pharmaceutical Scientists - November 15, 2016

Research being presented today at the 2016 American Association of Pharmaceutical Scientist (AAPS) Annual Meeting and Exposition, which is taking place Nov. 13 -17 in Denver, found that under certain conditions, the Zika virus can live for several hours on hard non-porous surfaces and still be highly contagious, but that some commonly used disinfectants are extremely effective in killing the virus. The research may have important infection control implications for both consumers and those who work in healthcare or lab settings.
