Troubling New Study On Working Pregnant Shows Why Flexible Jobs Matter

Studies Show

1:45 pm, June 28th | by Laura Donovan

Women who log in more than 25 hours of work per week while pregnant increase their chances of having smaller infants, according to new research in the journal, Occupational and Environmental Medicine. That?s not even the worst part: They grow into mutant pandas overtime. We kid, of course.

But if your job requires a lot of standing?like sales and teaching do?you?re a top candidate for this puzzling, possibly detrimental phenomenon. As noted by the Daily Mail, rigorous activity could reduce blood flow to the placenta, limiting the oxygen and nutrition levels that are supposed to go to the fetus. It?s unclear why those with sedentary professions would fall victim to this, but stress could very well be a contributing factor, as it pretty much exacerbates all problems.

Women shouldn?t necessary stop working entirely or go on bed rest when expecting, but this should tell employers that pregnant staffers need more flexibility in the months leading up to their child?s birth. It?s important to minimize time on one?s feet, as one of the researchers said ?it is not known whether these very subtle changes in growth trajectory have any significance in the long term.?

Plus, why give your kid yet another excuse to resent you? A 38-year-old acquaintance of mine still berates his mother for choosing not to breastfeed him. The next generation of kids will try to pull the same nonsense with their career moms?let?s avoid the fights ahead of time by being aggressive with our bosses about pregnancy flexibility.

Facebook's new 'Find Friends Nearby' feature: Creepy or clever?

13 hrs.

Rosa Golijan

Facebook quietly added a new feature to its mobile?website and apps this weekend. It's called "Find Friends Nearby" and it ... well, it does exactly what you'd think it might.

TechCrunch's Ingrid Lunden was among the first to call attention to the new feature, after a developer tipped her off.

You can access?Find Friends Nearby either through the iOS or Android?Facebook apps ? just open up the main?menu, tap "Apps," select "Find Friends," press "Other Tools," and then pick "Find Friends Nearby"?? or by?heading to http://fb.com/ffn?on your mobile device.

Note that you'll have to authorize either the apps or your browser to access your current location. This doesn't mean that?you're allowing either to reveal your location all the time though. As soon as you leave the Find Friends Nearby page, you'll be off the radar once again. (This makes sense because it prevents people from stalking you?invisibly or from being stalked without actively choosing to announce their location.)

While you are on the Find Friends Nearby page?? it looks the same in the apps and in the browser ? you'll be able to find out who happens to be both near you and staring at that same page.

The feature is incredibly convenient if you happen to be chatting with someone in person and want to add him as a Facebook friend. Rather than tapping out his name and wasting minutes scrolling through a list of similarly named individuals, you can just ask your new pal to open up the Find Friends Nearby page and add him with a quick tap.

Opening up the Find My Friends page, while convenient, also exposes you to potential awkward or creepy moments. There is always a chance that someone you are avoiding or not interested in interacting with ?will happen to have the same page open?? and spot your name. He or she would instantly know that you are nearby and quickly view the public information on your Facebook profile.

So the final verdict? Find Friends Nearby is incredibly convenient, but?? like many similar tools ? not without potential for disaster.?

Want more tech news, silly puns, or amusing links? You'll get plenty of all three if you keep up with Rosa Golijan, the writer of this post, by following her on?Twitter, subscribing to her?Facebook?posts,?or circling her?on?Google+.

Focusing on water for Central Everglades essential to reversing whole ecosystem's continuing decline

ScienceDaily (June 21, 2012) ? Twelve years into a multibillion-dollar state and federal effort to save the Florida Everglades, little progress has been made in restoring the core of the ecosystem, says a new congressionally mandated report from the National Research Council.Expedited restoration projects that improve the quality and amount of water in this area are necessary to reverse ongoing declines.A new federal pilot project offers an innovative approach to this challenge, although additional analysis is needed to maximize restoration benefits within existing legal constraints.

The report is the fourth biennial evaluation of progress made by the Comprehensive Everglades Restoration Plan, a project launched in 2000 that aims to reverse the ecosystem's decline while continuing to meet demands for water supply and flood control. The $13.5 billion effort comprises numerous projects to be completed over the next several decades.

The committee that wrote the report found that restoration remains primarily focused on the periphery of the central Everglades. Consequently, restoration efforts within the water conservation areas and Everglades National Park lag behind other portions.Progress has been made to improve the system's water quality, such as reducing phosphorus and finalizing negotiations for additional water quality projects.Nevertheless, there has been minimal success in increasing the amount and flow of water needed to restore the remnant system.Key components that depend on the amount of water in the system, such as the ridge and slough and tree islands, continue to degrade.

"Unless near-term progress is made to improve water quantity and restore water flow, ecosystem losses will continue, many of which would require decades to centuries to recover," said William Boggess, chair of the committee and professor and executive associate dean of the college of agricultural sciences at Oregon State University, Corvallis."However, bringing in more water, or even redistributing existing water flows before water quality is improved, risks introducing levels of contaminants that would have substantial effects on the ecosystem and possibly exceed legal limits.Analyzing the connections between water quality and quantity is one of the remaining challenges of the program, and will be a key component for moving forward."

The committee found that the Central Everglades Planning Project (CEPP) -- one of five U.S. Army Corps of Engineers pilot projects nationwide that will test a new accelerated project planning process -- is an important and promising new initiative.Its goal is to deliver an approved project implementation report on central Everglades restoration to Congress within two years instead of the typical six-year process.At the completion of the committee's report, CEPP remained at an early stage, and no specific project plans were available for the committee to review.

Over the past few years, scientific understanding has advanced and provides a solid foundation for decision making in the program, the committee said.Investment in cutting-edge research, consolidated and timely synthesis, and effective monitoring are critical to supporting sound choices.Additional use of integrated ecosystem modeling and decision support tools could facilitate restoration progress by clarifying potential restoration conflicts, identifying interim strategies for limiting further degradation of critical ecosystem components, and enhancing the capacity to address trade-offs in a more timely and integrated way.

The study was sponsored by the U.S. Army Corps of Engineers, South Florida Water Management District, and U.S. Department of the Interior.The National Academy of Sciences, National Academy of Engineering, Institute of Medicine, and National Research Council make up the National Academies.

Ford SYNC Inducted into Computer History Museum

?

?

MOUNTAIN VIEW, Calif., June 18, 2012 /PRNewswire/ --

• The Computer History Museum today adds award-winning Ford SYNC? in-vehicle connectivity system to its permanent collection
• Powered by Microsoft, SYNC's easily upgradeable and extendable platform enables Ford owners to take advantage of the latest developments in mobile communications
• More than 4 million Ford vehicles are already on the road with SYNC, a population expected to grow to more than 9 million by 2015 as SYNC goes global

When people think of the Computer History Museum in Mountain View, Calif., names such as Microsoft, IBM, Cray, Apple and Google come to mind. Today, those technological luminaries are joined by Ford as curators add the SYNC? in-car communications and connectivity system to the museum's permanent collection.

(Photo:? http://photos.prnewswire.com/prnh/20120618/DE26805)

"We are honored. SYNC has helped us move faster than what is usually assumed of an automaker, providing a new level of openness and access that has forever changed how we look at our business and respond to our customers," said Paul Mascarenas, chief technical officer and vice president, Ford Research and Innovation. "Ultimately, SYNC embodies what Ford is all about: going further to transform innovative ideas into products that are affordable, attainable and valuable to millions of people."

Said Alex Bochannek, curator and senior manager of the Computer History Museum: "As cars have transformed into mobile platforms for consumers' communication and entertainment needs, the intersection of automotive and computing developments is becoming an increasingly important area for the museum to consider.?

"Ford Motor Company's collaboration with Microsoft on SYNC technology is an example of this changing landscape," he added. "The Computer History Museum is pleased to add a first-generation Ford SYNC module to its permanent collection in support of our continued efforts to document the effects of computing on society at large."

SYNC is the award-winning in-car connectivity system that provides voice control for mobile phones and digital music players connected via Bluetooth? or USB. Ford co-developed the system with Microsoft using the Windows Embedded Automotive platform.

"When we first teamed up with Ford nearly a decade ago, we knew we wanted to develop a system that connected consumers' digital lifestyles to the vehicle they love today, and seamlessly for years to come ? regardless of the device," said Kevin Dallas, general manager, Windows Embedded at Microsoft. "Having SYNC inducted into the Computer History Museum's collection is a testament to the system's groundbreaking innovation and to all of the hard work of our engineers, both in Dearborn and Redmond, to deliver a product that continues to meet consumers' evolving needs and exceed expectations."

SYNC debuted in the 2008 Focus, Ford's most affordable car offering at the time, as a $395 option.

Within two years, SYNC became available in every new Ford Motor Company product. By early 2012, more than 4 million SYNC-equipped vehicles were on the road. By 2015, that number is expected to grow to 9 million as Ford introduces the technology into products around the world.

The SYNC software platform has provided for a regular cadence of new features, many of which have been made available to customers as a simple downloadable update they can install at home or by visiting a local Ford dealer. New features have included:

• 911 Assist? (2008) ? an automatic emergency calling feature that uses the customer's Bluetooth-paired cell phone to directly call 911 if there has been an airbag deployment.
• Vehicle Health Report (2008) ? an on-demand diagnostic report that gets produced on-board the vehicle and sent via data-over-voice through the customer's cell phone in order to be accessed through the www.syncmyride.com Web portal.
• SYNC Services (2009) ? with the addition of a GPS module to the SYNC module inside the car, Ford created an off-board network of service providers that could be accessed with a simple voice command, "Services," leveraging a customer's mobile phone voice plan for voice-activated, personalized news, traffic, turn-by-turn navigation, weather reports, business search and sports scores; only a few months later, more services were added to the cloud-based network, including on-demand horoscopes, stock quotes, movie listings and travel information.
• Send to SYNC (2010) ? using SYNC Services, customers could now send a destination address from either MapQuest or Google Maps straight to their car for easy download of turn-by-turn directions.
• Destinations App (2010) ? building on Ford's cloud-based network of services, the first smartphone app for SYNC was launched adding a new level of convenience for customers so they could search for and input destinations, even check traffic, while away from their car.
• AppLink? (2010) ? the groundbreaking feature that helped Ford be first to voice-activate and control smartphone apps, such as Pandora and Stitcher, by working with developers in their own native programming languages and leveraging the SYNC application programming interface (API); there are now 10 SYNC-enabled smartphone apps across all three major mobile platforms: iOS, Android and BlackBerry OS.

The birth of SYNC
In 2005, Ford ? long considered a "fast-follower" in technology ? was looking for ways to change both its perception and its culture.

"We saw connectivity as a way to change that paradigm," said Doug VanDagens, now global director of Ford Connected Services and an early team member working on the SYNC project.

At the same time, Microsoft was breaking into the automotive market with its Windows CE embedded operating system.

In April 2005, both Ford Executive Chairman Bill Ford and then-Microsoft CEO Bill Gates were featured speakers at the Microsoft Global Automotive Summit in Dearborn, Mich. The pair started to discuss how they could collaborate on bringing state-of-the-art connectivity into cars.

While consumers replaced mobile phones and digital media players every couple of years to keep up with the latest advances, vehicles typically lasted a decade or more. Relying on an embedded system could leave a car hopelessly outdated long before the end of its useful life.

Rather than force owners to pay for another wireless plan for their vehicles, Ford pursued connectivity platforms that would allow drivers to use the technology they already carried with them.

"By the end of 2005, Ford's Electronics and Electrical Systems Engineering group started active development of a platform that could be kept up to date with the latest technology trends throughout the life of the car," said VanDagens. "With Windows CE as the base, we could add new functionality through apps that owners could download from the Web and install with a USB flash drive."

Collaborating with suppliers, including voice recognition leader Nuance, they developed a robust and easy-to-use voice interface. This enabled drivers to make and receive phone calls and select songs, artists, albums, genres and playlists all while keeping their hands on the wheel and eyes on the road.

By January 2007, SYNC was ready to take center stage with simultaneous announcements at the North American International Auto Show in Detroit and the International Consumer Electronics Show in Las Vegas. Click here to view video of the CES presentation http://youtu.be/PCpec1sa_UM.

Designing the system around connecting to mobile devices proved to be fortuitous almost immediately. Just two days after the initial SYNC announcement, Apple introduced the iPhone. Within just a few years, smartphones went from a tiny niche to dominating the mobile phone market.

With hundreds of millions of people using phones running a wide array of apps able to stream media over fast wireless connections, SYNC was poised to take advantage.

"SYNC ultimately became a turning point for the redefinition of the automobile from just an ordinary transportation device into a technology platform that empowers consumers to take advantage of the latest innovations," said Venkatesh Prasad, another member of the early development team and now senior technical leader of open innovation for Ford Research and Innovation.

Review: New MacBook Pro is revolution for eyeballs, raid on wallet

23 hrs.

Wilson Rothman

I didn't think I would care much about a "Retina" display for a laptop. When I'm using my current laptop in a typical way, a?few feet from my face, I can't see the pixels anyhow.?So what would this revolutionary laptop with?pixels that are invisible to the human eye do for me? Turns out,?it bathes my eyeballs in a spa-like warmth the likes of which I haven't felt since I first stared deep into the high-res face of my first iPhone 4.

Don't call me a fanboy for that one. Just do yourself a favor and stare deep at?a Retina display on an iPhone 4 or 4S, or a competing phone with a ridiculously pixel-dense screen, like HTC's Rezound. When you're looking at the right image or picture, it feels like you can see for miles and miles, and it's relaxing. It's easier on the eyes, because your brain doesn't have to reconstruct reality from a pile of bricks. It simply?sees reality.?

And even at arm's length, like on a laptop monitor,?the difference?is clear. When I was browsing the Mac App Store on the new MacBook Pro, I pulled up iPhoto, and in the splash screen there was a mockup iPhoto?screen, and inside that screen were photos. I could see the detail in each of those tiny thumbnails, as if they were 3x5s sitting on a coffee table.

The other thing that I could tell immediately?about the new?screen is that there's far less glare. I have an anti-glare screen on my 2010 MacBook Pro, but colleagues in my office with standard screens live like vampires, shying away from sunlight, fearing reflections in their screens. When you set the new MacBook Pro next to an older model, you can see that Apple has cut down on glare drastically, and that?the visibility is simultaneously increased by newer?LCD technology that makes for better viewing at wider angles.

I'll shut up about the display now, but there's no downplaying its significance ? and the fact that it's a leading inflater of the price of the?newly redesigned MacBook Pro.

Whether you're seriously considering buying in or just curious about the new gold standard in laptops, you have to understand what's revolutionary about the MacBook Pro and why that will sooner or later become standard, at least in Apple's lineup.?Design and technological?innovations like these aren't meant to be kept at the high end. Just as unibody construction, solid-state memory and Thunderbolt interfaces have worked their way down into Apple's full MacBook line, so too will the glories that are today only found the admittedly expensive ? and hard to find ? new?flagship.

Another of these improvements can be heard in the speakers.

When my wife and I travel with the older MacBook Pro, and watch a movie on it?in a hotel room, we strain to hear dialogue. My wife has flat-out?banned the listening of music on that old laptop, too,?because it's so tinny. Well, the new next-gen MacBook Pro may be skinnier, but trust me, the sound coming out of it is a whole lot?fatter. You can really hear midrange and low-end, and when you crank the volume, the sound gets louder, rather than just peaking out in an ear-crushing way.

Under the hood, things get even more advanced. Instead of a hard drive, or even a typical "solid-state drive," where flash memory is stored in a hard-drive-shaped?enclosure, there is just a board that holds the flash memory, ranging from 256GB to 768GB. Flash memory is not cheap, especially the highest-quality kind needed for performance laptops, and that's why there's an?additional "early adopter tax" here:?Since Apple is hardwiring it?in, you have to pay for the internal memory you'll need?now, rather than wait to upgrade later, when the price inevitably?goes down. (Apple will however be offering RAM upgrades for the new MacBook Pro, according to a check of the Apple Store, and corroborated by support documentation.)

Pricey though it is, the benefit of hard-wired flash memory is exceptional performance: The laptop wakes up instantly when you open the lid, and when that lid is closed, your battery doesn't drain. There's a 7-hour battery life, says Apple, and the stand-by time is an incredible 30?days.

(While I wanted to share with you the significance of this laptop, I am not going to go into further?technical testing here. For an excellent technical review, pay a visit to our friends at Laptop, who have all the charts and graphs you'll need to know just how special this thing is.)

There are, of course, things that might not?excite you about the new MacBook Pro. It's not particularly lightweight, for instance. Weighing in at around 4.5 lbs., it's by no means heavier than the typical premium notebook, but it's not a miracle of lightness, either. In fact, because it has a similar weight and footprint to its predecessor, it's easy to forget about its remarkable thinness.

Another thing that might concern some is the lack of a DVD drive, but I am having a hard time remember the last time I even watched?a DVD, let alone burned one. For those still?interested in shiny silver disc handling, there is a $79 USB?SuperDrive, but it shouldn't be considered as a?precautionary purchase, because my guess is that most people won't need it.

"Need." Look at me. What an awful word to use when discussing this marvel.?Aside from visual artists, medical imaging technicians and mineralogists?? the sort of?professionals?for whom this kind of pixel density comes with immediate pay-off,?not to mention a tax write-off?? there's no way this baby is?a "necessity."

It is bragging right upon bragging right, envelope push upon envelope push, and most people who buy it will be doing it for the same reason they would buy a Mercedes-Benz CLS. To experience the height of quality??To fulfill a personal aesthetic hunger? To show off to friends and strangers alike? It makes no difference: The reason is certainly?not to get you to work and back.

So if you do buy this?? assuming all?other financial?obligations to society are covered, or you have more money than you could ever spend in your lifetime?? I say buy the $3,749 configuration. That maxes out the RAM at 16GB, the internal flash memory at 768GB and the processing speed at 2.7GHz.?Just don't be surprised when, a couple of years from now, you're standing in the coffee shop line?behind some little hipster who has a slim?new MacBook Air with all those specs, and that brag-worthy Retina screen,?and it only cost him $999.

Previously, scientists had been able to create and determine the structure of 'cages' formed by parts of the protein coats that encase other types of vesicles, but this study was the first to obtain high-resolution images of complete vesicles, budded from a membrane.Fri, 25 May 2012 10:36:36 EDThttp://www.sciencedaily.com/releases/2012/05/120525103614.htmhttp://www.sciencedaily.com/releases/2012/05/120524143527.htm There's nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses have come in the form of an advanced method for analyzing data from X-ray crystallography experiments.Thu, 24 May 2012 14:35:35 EDThttp://www.sciencedaily.com/releases/2012/05/120524143527.htmhttp://www.sciencedaily.com/releases/2012/05/120524123232.htm Researchers are using nanoparticles to simultaneously deliver proteins and DNA into plant cells. The technology could allow more sophisticated and targeted editing of plant genomes. And that could help researchers develop crops that adapt to changing climates and resist pests.Thu, 24 May 2012 12:32:32 EDThttp://www.sciencedaily.com/releases/2012/05/120524123232.htmhttp://www.sciencedaily.com/releases/2012/05/120524092932.htm Quantum physics and plant biology seem like two branches of science that could not be more different, but surprisingly they may in fact be intimately tied. Scientists have discovered an unusual quantum effect in the earliest stages of photosynthesis.Thu, 24 May 2012 09:29:29 EDThttp://www.sciencedaily.com/releases/2012/05/120524092932.htmhttp://www.sciencedaily.com/releases/2012/05/120523135527.htm Quantum computers may someday revolutionize the information world. But in order for quantum computers at distant locations to communicate with one another, they have to be linked together in a network.
