Physical exercise slows brain aging.

Even after the onset of senility or dementia, physical exercise like walking, climbing stair, lifting things has been found to improve memory and ability to plan and organize activities.

Some seniors may be in poor physical condition such that improvement seems unlikely, but improvement is always possible, often to surprising degrees. Little steps, little improvements add up to significant improvement, often quite quickly.

Researchers found that physical activities such as lifting things, ability to balance, taking a brisk walk or stairs instead of lifts improved the ability to plan, organize and remember things—which are cognitive functions known to deteriorate with dementia.

Success is enhanced by using numbers—count the numbers of steps, note how far the walk went, how many steps we climbed, how many times we lifted the can of beans, and watch those numbers increase.

Seniors should be encouraged to exercise regardless of their condition. Having someone to exercise with them helps them very much to exercise.

Just ten minutes of exercise helps brain power.

Just ten minutes of aerobic activity can boost brain power.

One group of test subjects sat and read a magazine, and another group did a ten minute ride on a stationary bicycle.

Then all were given a physical movement exercise that required eye movement and focusing.

Those who had exercised were more accurate in the task and had reaction times up to 14% faster than those who had sat reading.

Exercise increases blood and thus oxygen flow to the brain, as well as to all other organs.

Exercise programs on television use long, repeated exercise routines, but research has proven that even single short workouts also help significantly.

At least get up from your chair and walk around, better yet go out and walk briskly around the house, and your thinking will have improved when you sit back down. Likely you yourself will notice the improvement.

Google and Facebook rake in two-thirds of total world digital advertising revenue.

Digital advertising revenue in 2015 is estimated to have been a record $60 billion, with Google getting $30 billion and Facebook $8 billion.

The two got a third of total world revenue from advertising of all kinds.

They also took in about 90% of 2015’s increase in advertising revenue.

Pivotal Research analyst Brian Wieser said, “The digital-media industry has effectively become a dual monopoly in which Google and Facebook win almost everything, advertisers have to play by their rules, and other media companies ‘fight for the scraps.’”

This behavior is illegal. Where Oh Where is trust-busting Teddy Roosevelt?

Landslide South of Yakima

The landslide of approximately 20 acres on Rattlesnake Ridge south of Union Gap south of Yakima along Interstate 82 is currently moving at a rate of apx. 18 inches per week in a southward direction. Some 40 GPS sensors have been placed on the slide, and the movement of each of these is constantly monitored. The movement is ongoing, and geologists and engineers monitoring it predict a more rapid slide, a “slip,” is likely to occur in late January or February. The type of movement expected is a mostly sideways slide composed of blocks of basalt sliding on a weaker sedimentary layer. The scientists suggest the landslide will probably move south and accumulate into a quarry. Rockfall west and south may fall on Thorpe County Rd. which has been closed since late December. There is smaller chance that the slide could reach I-82 and hit homes south of the quarry, or reach the Yakima River. Many residents have evacuated as a precaution. Other preparations are in place and ready for actions as needed.

Apple asked to address cellphone addiction and resulting mental health issues

Several of Apple’s largest investors sent a letter to Apple on Saturday urging it to develop new software tools that would help parents control and limit phone use more easily and to study the impact of overuse on mental health.

The letter said, “There is a developing consensus around the world including Silicon Valley that the potential long-term consequences of new technologies need to be factored in at the outset, and no company can outsource that responsibility.”

Some have raised concerns about increased rates in teen depression and suicide and worry that phones are replacing old-fashioned human interaction. It is part of a broader re-evaluation of the effects on society of technology companies such as Google and Amazon.com Inc. and social-media companies like Facebook Inc. and Snap chat owner Snap Inc., which are facing questions about their reach into everyday life.

Facebook charged by investors and former executives with causing psychological addiction and harm to democracy.

When scientists started linking cigarettes to cancer, the tobacco industry silenced them—only acknowledging the extent of the truth decades later, under legal duress.

Imagine if, instead, they had given these researchers license to publish papers, or even taken the information to heart and crippled their own moneymaking machines for the good of their addicted users.

No one has accused Facebook FB 0.77% of causing cancer, but Mark Zuckerberg now stands at a similar crossroads.

In the face of pressure brought by a growing roster of Facebook investors and former executives, many of whom have publicly stated that Facebook is both psychologically addictive and harmful to democracy, the Facebook founder and chief executive has pledged to “fix” Facebook by doing several things, including “making sure that time spent on Facebook is time well spent.”

Smartphones Hijack Our Minds

Research suggests that as the brain grows dependent on phone technology, the intellect weakens.

In a 2015 Gallup survey, more than half of iPhone owners said that they couldn’t imagine life without the device.

We love our phones for good reasons. It’s hard to imagine another product that has provided so many useful functions in such a handy form. But while our phones offer convenience and diversion, they also breed anxiety. Their extraordinary usefulness gives them an unprecedented hold on our attention and vast influence over our thinking and behavior. So what happens to our minds when we allow a single tool such dominion over our perception and cognition?

Researchers recruited 520 undergraduate students at UCSD and gave them two standard tests of intellectual acuity. One test gauged “available cognitive capacity,” a measure of how fully a person’s mind can focus on a particular task. The second assessed “fluid intelligence,” a person’s ability to interpret and solve an unfamiliar problem. The only variable in the experiment was the location of the subjects’ smartphones. Some of the students were asked to place their phones in front of them on their desks; others were told to stow their phones in their pockets or handbags; still others were required to leave their phones in a different room. The results were striking. In both tests, the subjects whose phones were in view posted the worst scores, while those who left their phones in a different room did the best.

A second experiment conducted by the researchers produced similar results, while also revealing that the more heavily students relied on their phones in their everyday lives, the greater the cognitive penalty they suffered.

LightPhone is credit card size, offers nothing but voice phone calls.

Light Phone is a game-changing gizmo, a second device—smaller and lighter than a real phone and, at roughly credit-card size, less conspicuous—designed to be used as little as possible.

You can’t check email, text, browse the internet or swipe left with it. It harbors no seductive apps, has no color LCD screen. Tethered to your existing phone and number, it’s for voice calls only. Once you’ve pocketed the barely noticeable device, you leave your smartphone at home (or maybe in your glove box).

Light Phone costs $125, uses your existing number, is simple to set up, and it feels great to walk around with a device that’s only 1.3 ounces—miraculously about a third of what an iPhone weighs. It helped a user feel more engaged all weekend. And when he needed it, the Light Phone’s call quality was surprisingly good.

Relying on it, even a little, however, comes with drawbacks if you haven’t planned ahead. Because it can’t send or receive messages, browse the web or offer map directions.

Light Phone can be pre-ordered now, will start shipping by the end of February.

Scary Chip Flaws Raise Spectre of Meltdown

Apple, Google, Microsoft and other tech giants have released updates for a pair of serious security flaws present in most modern computers, smartphones, tablets and mobile devices. Here’s a brief rundown on the threat and what you can do to protect your devices.

At issue are two different vulnerabilities, dubbed “Meltdown” and “Spectre,” that were independently discovered and reported by security researchers at Cyberus Technology, Google, and the Graz University of Technology. The details behind these bugs are extraordinarily technical, but a Web site established to help explain the vulnerabilities sums them up well enough:

“These hardware bugs allow programs to steal data which is currently processed on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents.”

“Meltdown and Spectre work on personal computers, mobile devices, and in the cloud. Depending on the cloud provider’s infrastructure, it might be possible to steal data from other customers.”

The Meltdown bug affects every Intel processor shipped since 1995, although researchers said the flaw could impact other chip makers. Spectre is a far more wide-ranging and troublesome flaw, impacting desktops, laptops, cloud servers and smartphones from a variety of vendors. However, according to Google researchers, Spectre also is considerably more difficult to exploit.

In short, if it has a computer chip in it, one or both of the flaws likely affect it. For now, there don’t appear to be any signs that attackers are exploiting either to steal data from users. But researchers warn that the weaknesses could be exploited via Javascript — meaning it might not be long before we see attacks that leverage the vulnerabilities being stitched into hacked or malicious Web sites.

Microsoft this week released emergency updates to address Meltdown and Spectre in its various Windows operating systems. But the software giant reports that the updates aren’t playing nice with many antivirus products; the fix apparently is causing the dreaded “blue screen of death” (BSOD) for some antivirus users. In response, Microsoft has asked antivirus vendors who have updated their products to avoid the BSOD crash issue to install a special key in the Windows registry. That way, Windows Update can tell whether it’s safe to download and install the patch.

But not all antivirus products have been able to do this yet, which means many Windows users likely will not be able to download this patch immediately. If you run Windows Update and it does not list a patch made available on Jan 3, 2018, it’s likely your antivirus software is not yet compatible with this patch.

Google has issued updates to address the vulnerabilities on devices powered by its Android operating system. Meanwhile, Apple has said that all iOS and Mac systems are vulnerable to Meltdown and Spectre, and that it has already released “mitigations” in iOS 11.2, macOS 10.13.2 (but not yet macOS 10.12 Sierra used by the Shopper), and tvOS 11.2 to help defend against Meltdown. The Apple Watch is not impacted.

Your Kids’ Toy Gifts Could Be Spying On You

Toys connected to the internet could be a target for crooks who may listen in on conversations or use them to steal a child’s personal information.

​ Any internet-connected toys with microphones, cameras or location tracking may put a child’s or the parents’ privacy or safety at risk. That could be a talking doll or a tablet designed for kids.

Seattle’s Alaskan Way Viaduct has less than a year left.

The new tunnel under downtown will open mid-October 2018 — a few months early from previous estimates (or three years late from the original deadline).

Demolition of the Alaskan Way Viaduct could begin in early 2019.

The 8,300-ton 57-foot-diameter tunneling machine known as Bertha began tunneling beneath Seattle in July 2013. The machine completed its tunneling on April 4, 2017 and was fully dismantled and removed from the tunnel on Aug. 23, 2017.

Each direction of the tunnel will have two 11-foot travel lanes with an eight-foot safety shoulder and a two-foot shoulder. These lanes will ensure enough space for all vehicles and legal size trucks.

The 57-foot cutterhead was “gasketed” against the tunnel walls, allowing higher air pressure in front of it to prevent water from leaking in.

Replacing certain tools on the machine’s cutterhead required crews to work in the space between the cutterhead and the ground in front of the machine. Because the machine was underground and below the water table, it was necessary to stabilize the ground in front of the machine and pressurize this space. Crews stabilized the ground by injecting a type of clay, known as bentonite, into the front end of the machine. This created a seal that prevented water and soil from entering – and air from escaping – the work space.

Next, crews over-pressurized the space with compressed air, which pushed against the bentonite to counteract the ground and water pressure at the front end of the machine. This newly created “hyperbaric” work space had pressure levels higher than regular atmospheric pressure, similar to conditions found in an underwater dive. The graphic below illustrates the process.

When the $3.2 billion dollar Highway 99 tunnel opens under downtown Seattle, drivers will have to pay a toll to bypass downtown surface streets. Some studies suggest that drivers will likely avoid the tunnel toll and move to surrounding streets.

Tolls in the 9,270-ft SR 99 tunnel will be collected electronically, just like on all other toll roads in Washington by the GoodToGo system. Drivers will not need to slow down or stop at a toll booth.

A Good To Go! account and pass will be optional in the SR 99 tunnel. Just like other roads, drivers with a Good To Go! pass will pay the lowest toll rates.

If you already have a Good To Go! account, then you will not need to do anything else to use the SR 99 tunnel. Every kind of existing Good To Go! pass will work to pay a toll in the SR 99 tunnel.

Tolls will be based on time of day, similar to tolls on the SR 520 bridge.

Is your unlocking opening your phone an essential aid in your life or just a wasteful compulsive habit done for no purpose?

Finding that the average user unlocked their phone more than 10,000 times a year — or about 28 times a day — the researchers identified about 4,000 phone interactions a year as being “compulsive” (i.e., the owner had no particular act in mind when engaging).

Equally eye-opening was the finding that the highest decile of smartphone enthusiasts — or the top ten percent of users — opened their device 60-plus times every 24 hours.

Still, only a third of respondents earnestly believed they were addicted to checking their device.

“Our smart devices have become an essential part of modern life, and checking them regularly is second nature for most users,” says Greg Tatton-Brown, a spokesperson for Casumo, in a press release. “However, the instances of compulsive checking are much higher than we would have imagined, showing our phones are as much a habit as they are an aide to our busy lifestyles and an immediate source of entertainment, from wherever we are.”

Nuclear Nations Snub Anti-proliferation Treaty

Almost all nuclear nations express disrespect for recent nuclear anti-proliferation treaty because it does not recognize nations’ need to protect themselves against the North Korean threat and other current dangers of nuclear proliferation.

Nearly all ambassadors of the world’s nuclear powers will not attend this year’s Nobel Peace Prize ceremony which honours efforts to ban atomic weapons, the Nobel Institute said Thursday.

Russia and Israel will be the only exceptions, with their ambassadors due to attend.

Noting that the treaty comes “at a time of increased danger of nuclear proliferation”, the US embassy confirmed its lower level of participation.

“This treaty will not make the world more peaceful, will not result in the elimination of a single nuclear weapon, and will not enhance any state’s security,” it said in a statement to AFP.

Without mentioning North Korea by name, it stressed that “this treaty ignores the current security challenges that make nuclear deterrence necessary”, and reiterated Washington’s support of the 1968 global non-proliferation treaty.
