German Researchers Develop First Test for Zika Virus

The first batch has already been shipped to Brazil.

Part of what makes the Zika virus so scary—other than the fact that there’s no cure or vaccine—is that only one in five people infected will show symptoms. It’s a relatively surreptitious outbreak; an infected woman might not know she’s carrying the disease until she gives birth to a child with microcephaly.

But that will soon change. German biotechnology company Genekam has developed the first test to quickly detect Zika pathogens in a blood sample, according to Deutsche Welle, the country’s state-run international broadcaster.

“Our test examines DNA and works with chemicals that react to the Zika virus only,” Sudhir Bhartia, one of the developers, said. “Similar pathogens like dengue fever won’t show up in the results.”

Genekam has already shipped its first batch of kits directly to Brazil. In a less dire situation, the test would have to be approved through a long testing process, but authorities made an exception because of the rapid spread of Zika in South America.

However, access to the tests is limited. Only certain practitioners are authorized to administer the test, and the kits have been delivered only to specific labs that have a sufficient amount of resources and equipment. Luckily, the test is affordable, costing about 5 euros ($5.45 U.S.) for each use.

The test comes as a welcome development amidst the ongoing Zika outbreak, which has spread across 22 countries in the Americas, according to the CDC. Brazil, the epicenter of the disease, reports 3 to 4 million cases of Zika. There have been several reported cases in the United States, all from people who recently returned from affected regions. The World Health Organization has declared the virus a “global emergency.”

Last week, British biotechnical engineers began releasing genetically engineered male mosquitoes to quell the wild Aedes aegypti population, the species that carries Zika (as well as dengue fever and chikungunya) in Brazil.

Wealth inequality has been a hot topic of discussion as of late, but it's something that's occurred all throughout history. Class structure is a complicated issue, especially when you consider that haves and have nots have been in existence for over 4,000 years.

A study published in Science took a look at over 100 late Neolithic and early Bronze Age skeletons found in a burial site in southern Germany. The study "shed light on the complexity of social status, inheritance rules, and mobility during the Bronze Age." Partly by looking at their teeth and the artifacts they were buried with, researchers were able to discover that wealth inequality existed almost 4,000 years ago. "Our results reveal that individual households lasting several generations consisted of a high-status core family and unrelated low-status individuals, a social organization accompanied by patrilocality and female exogamy, and the stability of this system over 700 years," the study said.

Climate change means our future is uncertain, but in the meantime, it's telling us a lot about our past. The Earth's glaciers are melting at an alarming rate, but as the ice dwindles, ancient artifacts are being uncovered. The Secrets of the Ice project has been surveying the glaciers on Norway's highest mountains in Oppland since 2011. They have found a slew of treasures, frozen in time and ice, making glacier archeologists, as Lars Pilø, co-director of Secrets of the Ice, put it when talking to CNN, the "unlikely beneficiaries of global warming."

Instead of digging, glacier archeologists survey the areas of melting ice, seeing which artifacts have been revealed by the thaw. "It's a very different world from regular archaeological sites," Pilø told National Geographic. "It's really rewarding work.

When former Pittsburgh Steelers' center Mike Webster committed suicide in 2002, his death began to raise awareness of the brain damage experienced by NFL football players. A 2017 study found that 99% of deceased NFL players had a degenerative brain disease known as CTE (chronic traumatic encephalopathy). Only one out of 111 former football players had no sign of CTE. It turns out, some of the risks of traumatic brain injury experienced by heavily padded adults playing at a professional level also exist for kids with developing brains playing at a recreational level. The dangers might not be as intense as what the adults go through, but it can have some major life-long consequences.

A new PSA put out by the Concussion Legacy Foundation raises awareness of the dangers of tackle football on developing brains, comparing it to smoking. "Tackle football is like smoking. The younger I start, the longer I am exposed to danger. You wouldn't let me smoke. When should I start tackling?" a child's voice can be heard saying in the PSA as a mother lights up a cigarette for her young son.

On Tuesday morning, President Trump tweeted about some favorable economic numbers, claiming that annual household income is up, unemployment is low, and housing prices are high.

Now, just imagine how much better those numbers would be if the country wasn't mired in an economy-killing trade war with China, bleeding out trillion-dollar-a-year debts, and didn't suffer from chaotic leadership in the Oval Office?

At the end of tweet, came an odd sentence, "Impeach the Pres."

October is domestic violence awareness month and when most people think of domestic violence, they imagine mostly female victims. However, abuse of men happens as well – in both heterosexual and homosexual relationships. But some are taking it upon themselves to change all that.
