Beautiful New Images of Ebola Virus and Other Pathogens

When I told her that I wanted to major in microbiology, my best friend from childhood responded, “Are you sure you want to look in a microscope all day?”

But, as it turned out, a lot of microbiologists don’t use microscopes very often. I was one of them. The reason is because a substantial proportion of modern microbiology research uses the tools of molecular biology, for which microscopes are not needed.

U.S. Sees First Case of Bacteria Resistant to All Antibiotics

U.S. health officials on Thursday reported the first case in the country of a patient with an infection resistant to all known antibiotics, and expressed grave concern that the superbug could pose serious danger for routine infections if it spreads.

"We risk being in a post-antibiotic world," said Thomas Frieden, director of the U.S. Centers for Disease Control and Prevention, referring to the urinary tract infection of a 49-year-old Pennsylvania woman who had not traveled within the prior five months.

Of all the elements that make up Earth’s atmosphere, nitrogen is by far the most abundant. It is also one of the most inert. Nothing happens when you breathe it in, swallow it, or let it suffuse your skin.

How Half A Million U.S. Teens Are Texting Without A Data Plan

“What most people don’t realize,” says Jared Allgood, the co-founder behind the hot new messaging app that’s spreading quickly across U.S. middle and high schools, “is that we have a developing nation within America. It’s the American teen.”

Allgood’s app, Jott, has been seeing the kind of hockey-stick growth that app developers dream of: a 10x increase in users between March and May 2015, and almost entirely across that elusive demographic of teens. Adding 10-20,000 users a day it’s up to 500,000 active users on iOS, and is coming to Android this fall, when Allgood expects a jump in users as the new school year gets underway.

What’s compelling about Jott is that its growth isn’t the result of a snazzy new feature that all the kids are raving about. It’s simply met an economic need.

Delays in Receiving Zika Test Results Reported

        

Dr. Denise Jamieson - Medical Officer, Centers for Disease Control and Prevention

obgynnews.com/news - by Michele G. Sullivan - May 16, 2016

WASHINGTON – The Centers for Disease Control and Prevention is recommending blood or urine testing for all pregnant women with possible Zika exposure through travel or because they live in an endemic area, regardless of whether they are symptomatic, Dr. Denise J. Jamieson said at the annual meeting of the American College of Obstetricians and Gynecologists.

Couples interested in conceiving who live in or have traveled to areas of active transmission should be alert for any signs of infection, no matter how slight; if they notice any, they should be tested for exposure before attempting conception, Dr. Jamieson, a medical officer with the CDC’s division of reproductive medicine, said in a video interview.

Unfortunately, she said at an update on the Zika situation, labs that process Zika blood and urine samples are backed up, and test results are being “unacceptably delayed.”

World's carbon dioxide concentration teetering on the point of no return

The world is hurtling towards an era when global concentrations of carbon dioxide never again dip below the 400 parts per million (ppm) milestone, as two important measuring stations sit on the point of no return.

The news comes as one important atmospheric measuring station at Cape Grim in Australia is poised on the verge of 400ppm for the first time. Sitting in a region with stable CO2 concentrations, once that happens, it will never get a reading below 400ppm.

Lack of Zika-Specific Test Creates Dilemma for Some Pregnant Women

Washington - Pregnant women who’ve traveled to Latin America and the Caribbean are advised to be tested for the Zika virus afterward. But medical researchers have discovered there’s a problem with that advice: Some diagnostic tests will return positive results even when a person hasn’t contracted Zika.

That ambiguity can force pregnant women who fear giving birth to babies with severe brain damage to make life-changing decisions based on incomplete information.

The discovery by Zika researchers that current antibody tests don’t distinguish between Zika and dengue, another mosquito-borne virus, is the latest twist in the scientific world’s confrontation with a virus long thought relatively harmless but now thought able to cause serious birth defects as well as life-threatening complications in adults.

Dengue Antibodies Enhance Zika Infection?

CLICK HERE - STUDY - Dengue Virus Antibodies Enhance Zika Virus Infection

Previous flavivirus infection could help explain the severity of symptoms in some people infected during the ongoing Zika outbreak, researchers report.

The Scientist - by Tanya Lewis - April 28, 2016

Scientists at Florida Gulf Coast University and their colleagues have found that human cells were more likely to be infected with Zika virus in vitro if they contained antibodies to dengue virus. Their findings, detailed Monday (April 25) in a bioRxiv preprint, could help explain why Zika infection appears to be more severe in areas where dengue is endemic, and points to a potential unintended effect of dengue vaccination.

Antibodies to dengue can increase the virus’s infectivity for certain types of immune cells through a process called antibody-dependent enhancement (ADE), resulting in the production of more virus and more severe illness.
