Don’t keep cell phones next to your body, California Health Department warns | TechCrunch

Having worked with radio and radar in the military and also having had the danger of microwave radiation drilled into me as part of obtaining an amateur radio license, I’ve always thought that following prudent precautions with mobile phones is a good idea. I never, EVER keep my phone in my pocket while in a moving vehicle, a time when its transmitter is the most active. I limit the length of my calls, and choose text over voice whenever I can (texts use much less of the radio). I also make sure my phone switches to WiFi for its data whenever WiFi is available.

Smartphones are damn near indispensable but one has to respect the RF radiation they create. While there might not be agreement on the health effects they cause, mobile phones undeniably do create a lot of RF radiation.

As this week’s gutting of Net Neutrality shows, the telecom industry owns the FCC. If mobile phones really do pose a health risk don’t count on the FCC protecting you.

The California Department of Public Health (CDPH) issued a warning against the hazards of cellphone radiation this week. Yes, the thing we are all addicted to and can’t seem to put down is leaking electromagnetic radiation and now California has some guidance to safeguard the public.

The CDPH asks people to decrease their use of these devices and suggests keeping your distance when possible.

“Although the science is still evolving, there are concerns among some public health professionals and members of the public regarding long-term, high use exposure to the energy emitted by cell phones,” said CDPH director Dr. Karen Smith.

“Suspicious” event routes traffic for big-name sites through Russia | Ars Technica

Russia briefly hijacked key Internet sites Wednesday through manipulation of BGP, the Internet’s routing tables. In a war, you can bet that the Internet will be one of the first targets. Is Russia testing its plans?

Traffic sent to and from Google, Facebook, Apple, and Microsoft was briefly routed through a previously unknown Russian Internet provider Wednesday under circumstances researchers said was suspicious and intentional.

The unexplained incident involving the Internet’s Border Gateway Protocol is the latest to raise troubling questions about the trust and reliability of communications sent over the global network. BGP routes large-scale amounts of traffic among Internet backbones, ISPs, and other large networks. But despite the sensitivity and amount of data it controls, BGP’s security is often based on trust and word of mouth. Wednesday’s event comes eight months after large chunks of network traffic belonging to MasterCard, Visa, and more than two dozen other financial services were briefly routed through a Russian government-controlled telecom, also under suspicious circumstances.

North Korean TV appears to show early ‘A-bomb photo’ – BBC News

Remarkable. I’ve long suspected that North Korea has always been further along with its nuclear capability than the rest of the world realizes. Could this photograph be proof, or is this another case of NK “accidentally” exposing information to keep us all guessing?

On a related note, I’m fascinated with North Korea.

North Korean TV footage of an arms and munitions industry conference appears to show the country’s former leader Kim Jong-il inspecting one of the country’s first ever atomic bombs.

A 30-minute bulletin showing the 12 December conference in the capital Pyongyang has North Korea watchers agog at the picture’s appearance in the conference hall.

The photograph, never before seen in the West, is visible for only a few seconds as the camera sets the scene for the industry conference, attended by Supreme Leader Kim Jong-un, the son of the late Kim Jong-il. It hangs among others showing North Korea’s “achievements” in arms production, alongside scale models of ballistic missiles.Because of its fleeting appearance from a distance, experts are holding fire on a positive identification of the device as an atomic weapon. But the photograph has notable similarities to recent photographs of Kim Jong-un inspecting the country’s first (claimed) hydrogen bomb.

NASA Considers Magnetic Shield to Help Mars Grow an Atmosphere

I first read this story last week and it’s been on my mind ever since. It’s beyond our current capabilities to generate a planet-sized magnetic field but we can possibly block solar wind enough to bring Mars back to life. Utterly fascinating!

The Planetary Science Vision 2050 Workshop is happening right now at NASA headquarters in Washington DC. The workshop is meant to discuss ambitious space projects that could be realized, or at least started, by 2050.One of the most enticing ideas came this morning from Jim Green, NASA’s Planetary Science Division Director. In a talk titled, “A Future Mars Environment for Science and Exploration,” Green discussed launching a “magnetic shield” to a stable orbit between Mars and the sun, called Mars L1, to shield the planet from high-energy solar particles. The shield structure would consist of a large dipole—a closed electric circuit powerful enough to generate an artificial magnetic field.

A magnetic shield to protect Mars

Such a shield could leave Mars in the relatively protected magnetotail of the magnetic field created by the object, allowing the Red Planet to slowly restore its atmosphere. About 90 percent of Mars’s atmosphere was stripped away by solar particles in the lifetime of the planet, which was likely temperate and had surface water about 3.5 billion years ago.

Artificially lit surface of Earth at night increasing in radiance and extent | Science Advances

I have long been a proponent of streetlights, thinking that they reduce crime. Lately, I’ve been reconsidering my position, especially once I saw the stunning astrophotography my friend Rowland has been doing.

Dark skies are natural. Artificial street lighting is by definition not natural, and its increasing prevalence has repercussions that we are only beginning to understand.

I am now starting to think that, like air conditioning, electric light is meant for the indoors.

A central aim of the “lighting revolution” (the transition to solid-state lighting technology) is decreased energy consumption. This could be undermined by a rebound effect of increased use in response to lowered cost of light. We use the first-ever calibrated satellite radiometer designed for night lights to show that from 2012 to 2016, Earth’s artificially lit outdoor area grew by 2.2% per year, with a total radiance growth of 1.8% per year. Continuously lit areas brightened at a rate of 2.2% per year. Large differences in national growth rates were observed, with lighting remaining stable or decreasing in only a few countries. These data are not consistent with global scale energy reductions but rather indicate increased light pollution, with corresponding negative consequences for flora, fauna, and human well-being.

Facebook’s ‘People You May Know’ feature can be really creepy. How does it work? – Recode

When Facebook’s Android app apparently accessed my camera without my permission I banned it from my phone. This story might drive me from Facebook altogether.

This upcoming year will see me drastically curtail my Facebook usage. There are so many other things I can be doing than scrolling through cat photos, and also I am not convinced the information I share is always going to be used to my benefit.

Facebook has a pretty clear and straightforward company mission: Connect everybody in the world.

One of the ways it carries out that mission is by recommending new friends for you every time you open the app or website — essentially, the company identifies other people on Facebook that it thinks you already know, and nudges you to connect with them inside Facebook’s walls.

The problem with this feature is that it can be really creepy.

Facebook previously employed user locations to recommend friends, but says it has stopped doing that; Fusion recently wrote about a psychiatrist who claims her mental health patients were being prompted to connect with one another on the service. Not good.

When my colleague Jason Del Rey and I recently experienced a number of oddly timed recommendations, we started to get curious ourselves. How does Facebook generate these eerily coincidental recommendations?

How Facebook Figures Out Everyone You’ve Ever Met

In real life, in the natural course of conversation, it is not uncommon to talk about a person you may know. You meet someone and say, “I’m from Sarasota,” and they say, “Oh, I have a grandparent in Sarasota,” and they tell you where they live and their name, and you may or may not recognize them.

You might assume Facebook’s friend recommendations would work the same way: You tell the social network who you are, and it tells you who you might know in the online world. But Facebook’s machinery operates on a scale far beyond normal human interactions. And the results of its People You May Know algorithm are anything but obvious. In the months I’ve been writing about PYMK, as Facebook calls it, I’ve heard more than a hundred bewildering anecdotes:

A man who years ago donated sperm to a couple, secretly, so they could have a child—only to have Facebook recommend the child as a person he should know. He still knows the couple but is not friends with them on Facebook.

A social worker whose client called her by her nickname on their second visit, because she’d shown up in his People You May Know, despite their not having exchanged contact information.

A woman whose father left her family when she was six years old—and saw his then-mistress suggested to her as a Facebook friend 40 years later.

An attorney who wrote: “I deleted Facebook after it recommended as PYMK a man who was defense counsel on one of my cases. We had only communicated through my work email, which is not connected to my Facebook, which convinced me Facebook was scanning my work email.”

Connections like these seem inexplicable if you assume Facebook only knows what you’ve told it about yourself. They’re less mysterious if you know about the other file Facebook keeps on you—one that you can’t see or control.

Climate change:NC teens petition NC environment commission to cut fossil fuel and greenhouse gases | News & Observer

News broke today that Hallie is trying again, this time with friends, to get North Carolina’s environment back on track. Go, Hallie!

Hallie Turner was 13 years old when she stood outside a Wake County courtroom telling media crews with cameras trained on her that she planned to continue to fight for action on climate change despite her unsuccessful attempt to sue North Carolina over its environmental rules.

Now 15, Hallie is trying again to get the state Department of Environmental Quality and the state Environmental Management Commission to adopt a rule calling for a sharp reduction in emissions of carbon dioxide and other greenhouse gases over the next three decades. This time, two other North Carolina teens — Emily Liu, 16, of Chapel Hill, and Arya Pontula, a Raleigh 17-year-old, will join Hallie in petitioning the commission.

With the help of Ryke Longest at the Duke Environmental Law and Policy Clinic, and Our Children’s Trust, a Oregon-based nonprofit focused on climate change, the teens hope to persuade the state to adopt a rule ensuring that by 2050 carbon dioxide emissions would be down to zero.

“It would be a future in which you would not be burning fossil fuels to power your homes,” Longest said on Monday, the day before the teens plan to file their petition.

‘The strangest supernova we’ve ever seen’: A star that keeps exploding — and surviving – The Washington Post

An astonishing astronomical event is taking place. We are constantly shown that we have only the slightest idea of how the universe really works.

Some 500 million light-years away, in a galaxy so distant it looks like little more than a smudge, a star exploded five times over the course of nearly two years, spewing the contents of 50 Jupiters and emitting as much energy as 10 quintillion suns.

This isn’t even the first time this star has gone supernova: Astronomers believe this same body was seen exploding 60 years ago.

Somehow, this “zombie” star has managed to survive one of the most powerful, destructive events known to science — multiple times. It should make us question, researchers wrote Wednesday in the journal Nature, how much we really know about supernovas.

Why Nerds and Nurses Are Taking Over the U.S. Economy – The Atlantic

Manufacturing will fall. Retail will wobble. Automation will inch along but stay off the roads, for now. The rich will keep getting richer. And more and more of the country will be paid to take care of old people. That is the future of the labor market, according to the latest 10-year forecast from the Bureau of Labor Statistics.

These 10-year forecasts—the products of two years’ work from about 25 economists at the BLS —document the government’s best assessment of the fastest and slowest growing jobs of the future. On the decline are automatable work, like typists, and occupations threatened by changing consumer behavior, like clothing store cashiers, as more people shop online.

The fastest-growing jobs through 2026 belong to what one might call the Three Cs: care, computers, and clean energy. No occupation is projected to add more workers than personal-care aides, who perform non-medical duties for older Americans, such as bathing and cooking. Along with home-health aides, these two occupations are projected to create 1.1 million new jobs in the next decade. Remarkably, that’s 10 percent of the total 11.5 million jobs that the BLS expects the economy to add. Clean-energy workers, like solar-panel installers and wind-turbine technicians, are the only occupations that are expected to double by 2026. Mathematicians and statisticians round out the top-10 list.
