They thought they were white – DNA tests showed otherwise

They considered themselves white,: DNA tests told a more complex story

By Tara Bahrampour February 6, 2018 – Washington Post

As more Americans take advantage of genetic testing to pinpoint the makeup of their DNA, the technology is coming head to head with the country’s deep-rooted obsession with race and racial myths. This is perhaps no more true than for the growing number of self-identified European Americans who learn they are actually part African.

For those who are surprised by their genetic heritage, the new information can often set into motion a complicated recalibration of how they view their identity.

Data and medicine … A revolution in health care is coming – The Economist

Data and medicine … A revolution in health care is coming

Welcome to Doctor You

NO WONDER they are called “patients”. When people enter the health-care systems of rich countries today, they know what they will get: prodding doctors, endless tests, baffling jargon, rising costs and, above all, long waits. Some stoicism will always be needed, because health care is complex and diligence matters. But frustration is boiling over.

This week three of the biggest names in American business—Amazon, Berkshire Hathaway and JPMorgan Chase—announced a new venture to provide better, cheaper health care for their employees. A fundamental problem with today’s system is that patients lack knowledge and control. Access to data can bestow both.

Here in California, after years of drought, ferocious wildfires have consumed the tinder and everything in their path. Ignited on December 4, 2017, the Thomas Fire was not fully contained until January 12, 2018. Now ranked as the largest fire in California’s modern history, it burned about 281,900 acres, equivalent to the size of Dallas and Miami combined. It destroyed 1,063 structures and damaged another 280.

Torrential rainfall on January 9, a welcome respite for firefighters, brought more distress to residents in the area. Mudslides roared down fire scarred slopes, destroying and damaging hundreds of homes, as well as commercial property. Twenty people lost their lives; three are still missing.

Some Ways of Reducing Cellphone Radiation Exposure

Ways of Minimizing Cellphone Radiation Exposure

Scientists can’t seem to make up their mind about cell phones. Do they produce radiation? Yes. Is the radiation they produce harmful to us? They aren’t sure. However, putting all their reports together, a pattern of tips and precautions becomes clear.

The most important thing you need to know right away is that your phone sometimes transmits a stronger (and therefore more hazardous) signal, while at other times it will transmit very weakly or not at all.

Pencil Production

pencil is a little wonder-wand: a stick of wood that traces the tiniest motions of your hand as it moves across a surface. I am using one now, making weird little loops and slashes to write these words. As a tool, it is admirably sensitive.

The lines it makes can be fat or thin, screams or whispers, blocks of concrete or blades of grass, all depending on changes of pressure so subtle that we would hardly notice them in any other context. (The difference in force between a bold line and nothing at all would hardly tip a domino.) And while a pencil is sophisticated enough to track every gradation of the human hand, it is also simple enough for a toddler to use.    Continue reading

Why Guyana’s rainforests are a scientist’s dream

WWF – Blue Tarantula – Guyana

When herpetologist Andrew Snyder’s flashlight landed on something bright blue in the rainforests of Guyana, South America, he stopped and took a closer look.  It turned out to be a blue tarantula of the Ischnocolinae subfamily, a species most likely unknown to science.

“It was very exciting to say the least,” says the PhD candidate from the University of Mississippi.

“I had no idea that it would turn out to be such a stunning tarantula but I’m glad that I went with my instincts to double check.”        Continue reading
