The number of babies born in Puerto Rico with microcephaly and other birth defects caused by the Zika virus appears to be unexpectedly low — so low that experts are beginning to question whether the actual count is being significantly underreported by authorities on the island.

The world built more renewables for far less money last year, report UN and Bloomberg New Energy Finance.

thinkprogress.org - by Joe Romm - April 6, 2017

Stunning drops in the cost of wind and solar energy have turned the global power market upside down . . .

 . . . Unsubsidized renewables have become the cheapest source of new power — by far — in more and more countries, according to a new report from the United Nations and Bloomberg New Energy Finance (BNEF).

In just one year, the cost of solar generation worldwide dropped on average 17 percent, the report found. The average costs for onshore wind dropped 18 percent last year, while those for offshore wind fell a whopping 28 percent.

Thousands Of Bacteria-Infected Mosquitoes Released To Fight Zika & Other Viruses

           

miami.cbslocal.com - April 18, 2017

On Tuesday, the Florida Keys Mosquito Control District released 20,000 male mosquitoes infected by the Kentucky-based company MosquitoMate with naturally occurring Wolbachia bacteria.

The offspring produced when the lab-bred mosquitoes mate with wild female mosquitoes won’t survive to adulthood. Male mosquitoes don’t bite, and Wolbachia is not harmful to humans.

First ever observed case of ‘river piracy’ saw the Slims river disappear as intense glacier melt suddenly diverted its flow into another watercourse

theguardian.com - by Hannah Devlin - April 17, 2017

An immense river that flowed from one of Canada’s largest glaciers vanished over the course of four days last year, scientists have reported, in an unsettling illustration of how global warming dramatically changes the world’s geography.

The abrupt and unexpected disappearance of the Slims river, which spanned up to 150 metres at its widest points, is the first observed case of “river piracy”, in which the flow of one river is suddenly diverted into another.

'It Scares Me': Permafrost Thaw in Canadian Arctic Sign of Global Trend

Canada is melting.

Like a popsicle taken out of the freezer and left on the counter, the permanently frozen ground in the northern reaches of this country is thawing at an ever faster rate . . .

 . . . For years now, buildings in Inuvik have been gradually sinking into the ground as it softens. Others are so unstable, they are literally sliding off their foundations . . . 

 . . . This is where a local problem becomes a global concern.

Scientists in the Northwest Territories, Alaska and Siberia are now realizing that as the ground under them melts, it will not only make life harder for the people living in the Arctic, but will in fact speed up climate change around the globe.

Why People Have to Learn to Live with Wildfires

CLICK HERE - STUDY - PNAS - Adapt to more wildfire in western North American forests as climate changes

grist.org - by Bobby Magill - April 17, 2017

Communities across the Western U.S. and Canada may have to adapt to living with the ever-increasing threat of catastrophic wildfires as global warming heats up and dries out forests across the West, according to a University of Colorado study published Monday.

Residents living in neighborhoods adjacent to forests — known as “wildland-urban interface” zones — will have to accept that many wildfires may have to be allowed to burn and that building new homes in fire-prone forests should be discouraged, the study says.

Firefighters and policymakers will also have to adapt in new ways as catastrophic wildfires burn more land and destroy more homes than ever before.

cidrap.umn.edu - Lisa Schnirring - April 14, 2017

The largest genome sample ever analyzed for a human epidemic reveals that the West Africa epidemic unfolded with small, overlapping outbreaks as the virus spread over short distances and that urban settings amplified the spread.

Meanwhile, another study harnessed different advanced scientific tools in the blood of a single sick patient to detail gene-level response during infection.

Zika Found in Common Backyard Asian Tiger Mosquito

nbcnews.com - by Maggie Fox - April 14, 2017

A common backyard mosquito can be infected with the Zika virus and it may pass the virus along in its eggs, researchers reported Friday.

The findings add to worries that the Asian tiger mosquito, scientifically known as Aedes albopictus, could help spread the virus as mosquito season hits temperate regions of the world.

The study, published in the Journal of Medical Entomology, doesn't prove that tiger mosquitoes can spread Zika, which causes severe birth defects. But it adds to evidence that they might.

The Texas Department of State Health Services warned this week of multiple ongoing mumps outbreaks. The surge, which includes 221 cases this year, constitutes the highest incidence of mumps in the state in 22 years.

Mumps is a contagious disease caused by a virus that spreads from person to person through saliva and mucus.

New CRISPR Tool Can Detect Tiny Amounts of Viruses

The Cas13a enzyme causes collateral RNA damage that is the heart of a new diagnostic system, SHERLOCK, that can detect minute quantities of virus and much more.  Broad Institute

 . . . That’s the realm of SHERLOCK, a new diagnostic system that can detect attomolar levels of viruses in a sample and also distinguish Zika from its close relative, dengue. This exquisitely sensitive and specific tool promises to help detect diseases that other diagnostics miss, and it’s simple and cheap to use. Sexier still, it exploits a variation of CRISPR, the genome-editing method that has become the rage in biology.

UK Scientists: Samples from Syrian Attack Test Positive for Sarin

Samples taken from the alleged chemical weapons attack in Syria last week tested positive for the nerve agent sarin, the British delegation at the world's chemical weapons watchdog said on Thursday.

"UK scientists have analyzed samples taken from Khan Sheikhoun. These have tested positive for the nerve agent sarin, or a sarin-like substance," the delegation said during a special session at the Organisation for the Prohibition of Chemical Weapons in The Hague.

Earlier testing by Turkish authorities had also said the chemical used on April 4 was sarin.

Nigeria: Meningitis - the Killer Disease Ravaging Nigerians

allafrica.com - April 6, 2017

 . . . Nigerians should take precautions against meningitis . . .

 . . . The disease has also spread to 16 states, the Federal Capital Territory and 90 local government areas in the country. States affected so far are Zamfara, Katsina, Sokoto, Kebbi, Niger, Nassarawa, Jigawa, Gombe, Taraba , Yobe, Kano, Osun, Cross Rivers, Lagos, Plateau and FCT . . .

 . . . although this was not the first time or the worst epidemic ever faced by Nigeria, this round of the epidemic has come with a difference, as all previous epidemics were caused by Neisseria Meningitides type 'A' but this year's own was recording Neisseria Meningitides type C in epidemic proportion for the first time.

At a research lab on top of a forested hill overlooking Hong Kong, scientists are growing viruses. They first drill tiny holes into an egg before inoculating it with avian influenza to observe how the virus behaves.

This lab at Hong Kong University is at the world's forefront of our understanding of H7N9, a deadly strain of the bird flu that has killed more people this season — 162 from September up to March 1 — than in any single season since when it was first discovered in humans four years ago.

International Research Effort Reveals Major Insights Into Spread of West African Ebola Epidemic

CLICK HERE - RESEARCH - Nature - Virus genomes reveal factors that spread and sustained the Ebola epidemic

An international effort to analyze the entire database of Ebola virus genomes from the 2013-2016 West African epidemic reveals insights into factors that sped or slowed the rampage and calls for using real-time sequencing and data-sharing to contain future viral disease outbreaks.

Published today in the journal Nature, the analysis found that the epidemic unfolded in small, overlapping outbreaks with surprisingly few infected travelers sparking new outbreaks elsewhere, each case representing a missed opportunity to break the transmission chain and end the epidemic sooner.
