What do you know your neighbor? You are saving the planet



Meet your neighbor helps save the planet. That is the main finding of a study that socializing with neighbors leads to beneficial behaviors for the planet, even more than spending time with friends or family.

The study, published in Environment and Behavior, found that those who visit their neighbors are more likely to cultivate positive habits on the environment, specifically in relation to the conservation of water and energy consumption of organic fruits and vegetables and use automotive sound.

"These findings suggest that our neighbors play a unique and crucial for us to act on climate change role," says study author Thomas Macias, University of Vermont. "Surprisingly, the effects in favor of ecology were higher from the relationship of people to their neighbors than dealing with relatives or close friends."

Researchers attribute the differences, in part, to the fact that with relatives cultural and socioeconomic backgrounds are shared, which is a "similarity that provides emotional benefits, but limited exposure to important new ideas," says Macías, professor of Sociology in that university.

In contrast, the neighbors are relative but sufficiently different to expose a greater amount of fresh information, such as related issues and environmental practices.
The shared geography means that the neighborhood discussions gravitate naturally toward sustainability issues.
To identify predictors of 'green behavior', the researchers used US General Survey 2010, the largest and newest in terms of attitudes and behaviors related to the environment in that country behaviors inventory. Scientists compared the results with green three variables: personal relationships, generalized trust and participation in community organizations.

"The neighbors may be important role models," says Macias. "Talks neighborhood, exchanges sidewalk and neighborhood visits can be some of the best ways to learn about environmentally friendly practices."

Conclusion: Be kind to your neighbors; could be the secret to greater action on climate change, say researchers.

What do you know about cell differentiation ?

cellular differentiation is the process by which a less specialized cell becomes a more specialized cell type. Different tissues have different kinds of cells.

Differentiation occurs many times during the development of a multi-cellular organism as the organism changes from a single zygote to a complex system of tissues and cell types. Differentiation is a common process in adults as well: adult stem cells divide and create fully-differentiated daughter cells during tissue repair and during normal cell turnover.

What do we know about Apple's processor?





Apple's A5 processor has had some long legs. Originally introduced in the iPad 2 in early 2011, the chip has since proliferated across Apple's entire lineup—versions of it have been included in the iPhone 4S, the Apple TV, and the fifth generation iPod touch. Even the A5X in the 2012 iPad simply pumps up the A5's graphics capabilities while leaving the actual Cortex A9 cores untouched. Between the new iPod touches and the $99 iPhone 4S, it looks like the A5 is going to be for sale well into 2013 and beyond.
If the A5 is any indication, then, we'll be spending the next few years with the A6 chip that Apple introduced in the iPhone 5 yesterday. While the A5 is a thoroughly known quantity at this point, Apple's tendency to avoid talking about specifications means that we know next to nothing about what makes it tick. All we have now are three vague promises: compared to the A5 in the iPhone 4S, the new A6 promises "up to" two times the CPU and graphics performance; the A6 is 22 percent smaller than the A5; and the battery life of the new iPhone is slightly better than the battery life of the 4S. Absent any actual technical data about the new SoC, we're left to do the math ourselves.

Size and battery life

The cause of the reduced size and increased battery life of the iPhone 5 is pretty easy to guess: while the A5 chip in the iPhone 4S is still manufactured on the A5's original 45nm process, the A6 is probably manufactured on Samsung's 32nm process—Apple has already used this process on the A5 in the revised iPad 2 and the most recent Apple TV (and, in all likelihood, the newest iPod touch). Using the new process on an existing design would help Apple and Samsung to work out any kinks, clearing the way toward making a new chip on the same process. Intel's "tick-tock" processor release cadence uses the same methodology to reduce yield issues and other problems that can come from trying to make a new chip on a new process at the same time.

The 32nm Apple A5 is 41 percent smaller than the 45nm version in the iPhone 4S, so a 32nm Apple A6 would have some room to grow while still remaining smaller.

According to Chipworks, the 32nm A5 is about 41 percent smaller than the 45nm version, so a 32nm A6 would have room to add more silicon while still remaining smaller in absolute size. The 32nm A5 in the revised iPad 2 also delivers a 20 to 30 percent battery life increase over the original version with the 45nm chip, so the ten-or-so percent increase in battery life for the iPhone 5 is also pretty plausible, even given the higher-performing SoC.

Increased performance

With all of that in mind, let's look at these doubled performance claims. To get this big of a jump, you can either (1) double the hardware, going from the dual-core CPU and GPU in the A5 to quad-core parts in the A6, or (2) use newer, more efficient architectures, possibly combined with higher clock speeds (increasing clock speeds enough to get twice the performance from the same architecture would probably be too onerous from a power consumption perspective).
So, does the A6 use a quad-core Cortex A9-based chip combined with a quad core GPU? Let's look at the 2012 iPad's A5X, which uses a quad-core GPU to double the A5's graphics power and drive the 2048x1536 Retina Display. Our pals at Chipworks put the die size of the 45nm A5X at 12.90mm by 12.79mm (or 165mm, total), while the 45nm A5 is just 10.09mm by 12.15mm (or 122.6mm, total). Let's assume that if Apple decided to shrink the A5X using Samsung's 32nm process, that the die size would shrink by the same 41 percent, putting the size of a theoretical 32nm A5X at about 97.35mm, or about 21 percent smaller than the 45nm A5.

Enlarge / The quad-core GPU in Apple's A5X would make it a big chip, even at 32nm.

Now, keep in mind that while Apple says the A5X doubles the graphics performance of the A5, its CPU performance is identical to the older chip. Our 32nm A5X is about the right size and it has the right graphics performance, but it doesn't increase the CPU performance the requisite amount. Thus, it's fair to say that the A6 isn't using a quad-core CPU and GPU to achieve the stated gains.
There's also another reason to go with a faster dual-core CPU than a slower quad-core design: iOS and its apps have been running on the dual-core A5 for some time and as such are already optimized for two cores, and adding another two cores would only unlock those performance gains for developers who put in the extra work.
For these reasons, I think the current scuttlebutt is correct: the A6 is going to be the first chip to market based on the Cortex A15 processor architecture, which is said to be 40 percent faster than older Cortex A9 chips at equal clock speeds. That, combined with higher clock speeds (the A5 in the iPhone 4S is clocked at just 800MHz), could easily get us twice the CPU performance while still using a dual-core design. Even if the two cores are larger than two Cortex A9 cores, they're still not as big as four Cortex A9 cores.
The same holds true for the GPU side: by our calculations, there's probably not enough room for the A5X's quad-core Imagination Technologies SGX543MP4 along with the A15 cores, given what we know about the size of the A6, but a dual-core, faster-clocked Series 6 GPU from Imagination Technologies could likely achieve the same performance while using less space than four less-powerful cores.
Many things have to be true for these assumptions to work out: if Apple is using a 28nm process instead of a 32nm process, or if the A6 is using the same 512MB of RAM as the A5, either of those factors would probably be enough to throw off our math. But given that this is a major chip revision for Apple and that it will probably be serving in not just the next iPad, but future iterations of the Apple TV and iPod touch for the next few years, the use of forward-looking technology makes more sense than would beefing up old technology with more cores or higher clock speeds.
When we know more about the A6 for sure, you can be sure that we'll take a closer look at the chip and its implications for the rest of the market and for current and future Apple devices. For now, this represents our best guess.

What do you know about White Lake?



2010_06_0664.JPGWork along White Lake included restoring wetlands, controlling nuisance plant species and planting native species to increase diversity. Grasses along the shoreline are seen at Whitehall's Svensson Park in this file photo. Svensson Park was one of the projects' seven sites of focus.
Muskegon Conservation District and the White Lake Public Advisory Council are conducting a survey to measure how effective their public education programs about restoring habitat along White Lake were.
The survey is very similar to one conducted before the habitat restoration program started, Muskegon Conservation District Project Manager Dallas Goldberg said, to gauge if education programs about invasive species, shoreline softening and White Lake’s environmental challenges were effective.
“If our end survey shows, for instance, that phragmites is an invasive species that people don’t understand, then we need to do more education,” he said.
The survey can be accessed through www.muskegoncd.org/whitelakepac

What do you know about Country Fest at Gillette Stadium?



Foxborough is expected to see over 100,000 country fans at Gillette Stadium this weekend as Kenny Chesney and Tim McGraw wrap up their 2012 “Brothers of the Sun” Tour. Concerts will be held Friday and Saturday, beginning at 4:30 p.m.
The New England Country Music Festival atGillette Stadium has become an annual event in Foxborough since its inception in 2004.
The show, referred to by many concertgoers as “CountryFest,” features some of the industry’s biggest stars on one stage and this weekend will be no different as Kenny Chesney returns to Foxborough for the seventh time as the festival’s headliner and he’s bringing some all-star friends with him.
Jake Owen, Grace Potter and Tim McGraw will join Chesney on stage this weekend (Friday and Saturday) for the ninth annual Country Musical Festival in front of sellout crowds of 50,000 to 55,000 people each night.
“It’s the largest country music event in New England each year, and country music continues to gain in popularity,” said Gillette Stadium spokesperson Jeff Cournoyer.
The festival enjoyed initial success in 2004 and 2005 before exploding in 2006. In that year, the Gillette Stadium concert became the top-grossing country music show in history and "Country Fest" was born.
The ticket demand over the years has increased steadily as country music continues to gain popularity throughout New England. As a result of the overwhelming interest, Gillette Stadium has added a second day to the festival. Each show is similar – featuring the same artists – and is meant to give more fans an opportunity to experience the festival.
In advance of the two-day festival, here are five things you need to know about Country Fest weekend in Foxborough:
1. Parking Ban in Residential Areas will be Enforced and Other Parking and Event Entry Information
Stadium parking lots are scheduled to open to general parking at 1:30 p.m. on Friday and Saturday. Foxborough Police and Gillette Stadium personnel ask fans not to arrive prior to lots opening at 1:30 p.m.
Other important information for those attending Friday or Saturday’s event:
  • All passengers in vehicles must have a ticket for entry into Gillette Stadium parking lots
  • Transportation of alcohol between parking lots will not be allowed
  • No tailgating will be allowed after 5:30 p.m.
While some concertgoers may view security at this weekend’s event as strict – Cournoyer says Gillette Stadium personnel works closely with local and state police to ensure safety at all stadium events, especially ones that produce record crowds.
“As with any major event, we've worked closely with [Foxborough Police Chief Edward O'Leary], his team and the Massachusetts State Police to continue to improve traffic management, as well as to identify and address any public safety issues,” he said. “We make tweaks each year to try to improve on previous events. It has been a successful partnership.”
Foxborough residents are reminded that the town’s parking bylaw that bans parking for a fee on residential properties during Gillette Stadium events will be in effect Friday and Saturday. If residents are caught parking cars on their property for money, they will be subject to a $100 fine for each car in violation on that property. For more on the parking bylaw, click here.
As for general parking, the following rates apply:
  • $40 for cars
  • $125 Limos
  • $125 RV's and oversized vans/cars
  • $200 busses
Note that Gillette Stadium Lots are cash only. For more parking information, click here.
2. Sellout Crowds Mean Traffic Delays in Area
Two sellout crowds of 50,000 to 55,000 fans are expected in Foxborough on Friday and Saturday to see Kenny Chesney’s “Brothers of the Suns” Tour. Officials advise those travelling through the area to plan ahead and expect traffic delays similar to New England Patriots games, especially Friday night, where concert traffic will be added to the evening commute.

3. The Dos and Don’ts at Gillette Stadium During Concerts
Note the following will not be allowed in Gillette Stadium Parking Lots:
    • Any vehicle towing a trailer (this includes fifth-wheel RV units).
    • Professional catering trucks and or services without prior written approval from Stadium Management.
    • Excessive tailgate setups that impede on customers parked around your vehicles, emergency access or deemed to be unsafe or inappropriate by Stadium Management.
    • Any type of swimming pool, portable pool, hot tubs, water filled pickup trucks, or the like.
    • Branded vehicles that Stadium Management determines to be advertizing to the general public.

      4. Did You Know …
      • While Chesney has made the New England Country Music Festival the largest concert series in New England, he did not headline the first Country Fest in 2004. Do you know the artist who did? Here’s a hint … his bar and grill is located in Patriot Place. That’s right, country fans … Toby Keith headlined the 2004 Country Music Festival.
      • This year will mark Chesney’s seventh Country Fest, which included consecutive appearances from 2005-2009. In 2010, while Chesney took a break from touring, Brad Paisley headlined the event. Chesney returned for two performances last August at Gillette Stadium, even with Tropical Storm Irene on the verge of hitting the region.
      • Gillette Stadium is often Chesney’s last stop on his summer tours because it is one of his favorite venues.
      When in New England, Chesney often embraces the culture of the crowd. In past performances at Gillette Stadium, he has invited Boston Red Sox and New England Patriots players on stage with him during his shows and features a slideshow of photos and video of Boston and the surrounding area during the performance of his song, “Back Where I Come From.”
      5. Lineup of Artists and Possible Set Lists for Performers
      Country artist Jake Owen and his hit “Barefoot Blue Jean Night” will open the ninth annual New England Country Music Festival; taking the Gillette Stadium stage at 4:30 p.m. The rest of the musical lineup is as follows:
      • Potter and the Nocturnals
      • McGraw (on stage around 6 p.m.)
      • Chesney
      To give fans attending Country Fest this weekend an idea of what they may hear, we’ve done some research to see what songs these artists have been performing on “The Brothers of the Sun” Tour. Here’s a look at the set lists from the tour’s last three shows. Information courtesy of www.setlist.fm.
