Raf Simons' designs for Christian Dior were made for major moments. Thankfully, stars like Jennifer Lopez know when it's time to whip out a dramatic outfit.
The actress chose a look from Dior's pre-fall 2013 collection to receive her star on the Hollywood Walk of Fame yesterday. The peach and white confection featured a cashmere and silk top and Raf's signature hoop skirt. Lopez rounded out the ensemble with H.Stern earrings and black Brian Atwood heels.
Even though the outfit has been worn before, J.Lo's glam updo and subdued makeup made the look her own. (And kudos to Jen for choosing a mascara that didn't run when she teared up during a speech.) See Lopez in Dior below and tell us what you think!

Results from world's largest human cognitive performance dataset published in Frontiers in Neuroscience
Lumosity, the leading brain training company, today announced a new web-based, big data methodology for conducting human cognitive performance research. Lumosity's research platform, the Human Cognition Project, contains the world's largest and continuously growing dataset of human cognitive performance, which currently includes more than 40 million people who have been tracked for up to 6 years. The study, published today in the open-access journal Frontiers in Neuroscience, examined how Lumosity's dataset can provide insights into the lifestyle correlates of cognitive performance and the impact of age on learning rate.
Human cognitive performance research is typically conducted through experiments in the laboratory, with small numbers of participants often limited to university undergraduates and requiring in-laboratory follow-ups. This approach limits the kinds of questions that can be studied, the number and demographics of participants, and can be time-consuming and costly.
"New technologies and research platforms have the potential to transform the speed, scale, efficiency and range of topics in which neuroscience research is conducted," said P. Murali Doraiswamy, Professor of Psychiatry at Duke University Medical Center and member of the Duke Institute for Brain Sciences, and co-author of the study. "This study is interesting because it brings to light the possibilities of what we can uncover by taking a big data approach to cognitive performance research."
The study presented two examples of research that can be conducted using Lumosity's dataset. Using survey results and a subset of the dataset tied to baseline performance on three cognitive exercises, the first study examined the effects of sleep and alcohol consumption on cognitive abilities, including speed (N = 162,462), memory (N = 161,717), and flexibility (N = 127,048). The study found that cognitive performance in all three tasks was most efficient, on average, for users reporting seven hours of sleep each night. The study also found that low to moderate alcohol intake a self-reported one or two drinks per day was associated with better performance in all three tasks, with brain performance scores decreasing steadily with every additional drink.
The second study examined how learning ability changes over the lifespan and how aging might affect learning across distinct cognitive abilities. The study included adults ages 18-74, and looked at how age influences improvement over the course of the first 25 sessions of a cognitive task. Tasks that rely on fluid intelligence, which contribute to learning, problem solving, and the ability to adapt to novel challenges such as working memory (N = 22,718) and spatial memory tasks (N = 23,109), were compared to tasks that rely on crystallized knowledge, which draws on accumulated knowledge and skills from your life experience such as verbal fluency (N = 107,478) and basic arithmetic (N = 41,338). The study found that the amount of improvement decreased as age increased, and that performance on tasks that rely on fluid intelligence decreased with age at a faster rate than the tasks that rely on crystallized intelligence. This finding supports the notion that, although raw cognitive performance peaks in young adulthood, the lifelong accumulation of knowledge compensates such that older adults can still perform at a high level.
"The goal of the Human Cognition Project is to rapidly and efficiently advance our understanding of the brain," said Daniel Sternberg, Ph.D, Data Scientist at Lumosity and lead author of the study. "We're excited for the potential that big data holds for conducting large-scale, collaborative, global research on human cognition. We're particularly interested in applying the knowledge we gain from this research in real-world settings where they can help people live better, fuller lives."
The Human Cognition Project works with researchers worldwide to study human cognitive performance. The technology supports both experimental research, where independent researchers design and conduct studies on the effects of computerized cognitive training, and observational research, where collaborators explore data from Lumosity's continuously growing database.

Small 'forage fish' are a crucial source for larger animals in the ocean ecosystem. Without little fish, there can be no big fish. Pacific coast fishing leaders should thus adopt safeguards to prohibit fishing of saury until it can be shown that this would not adversely impact the ecosystem.
By Paul Shively,?Op-ed contributor / June 19, 2013
An infographic from The Pew Charitable Trusts shows an oceanic ecosystem chain. Op-ed contributor Paul Shively writes: 'To its credit, the [Pacific Fishery Management Council] unanimously adopted a fishery ecosystem plan' whose 'top priority is to make sure that no new fishing begins on forage species without first evaluating the effect on the larger ecosystem.'

When people think of a healthy ocean, the first thing that comes to mind is usually a large iconic animal, perhaps a humpback whale leaping majestically out of the water or a pelican swooping low across the ocean surface. In my case, I?m hooked by the thrill of a big salmon as it pulls the line off my reel.

Tiny fish play a major role in the ocean's food web. Commonly known as forage fish, small schooling fish like herring and anchovies are a crucial food source for larger, more familiar species like tuna, whales, and seabirds. The Pew Environment Group produced this animation to show how reasonable limits on catching forage fish can help maintain a vibrant and productive Pacific coast ecosystem for generations to come.
All of these animals dine on vast schools of tightly packed prey fish, commonly referred to as forage fish. Scientists and fishermen are becoming increasingly aware of their singular importance as the fuel that drives productive coastal ecosystems. At the same time, global demand is growing to catch forage fish for secondary purposes such as chicken feed, fertilizer, and bait for industrial longline fishing overseas.
But catching too many of these forage fish can severely disrupt the ocean life that they sustain. A lack of forage fish can have serious repercussions ? especially for the fishing industry. Without little fish, there can be no big fish.
That?s why many fishing and conservation organizations ? including The Pew Charitable Trusts ? are rightly advocating for new measures to safeguard forage fish. The Pacific Fishery Management Council, which is responsible for managing marine fish on the West Coast, will have the opportunity to adopt some of these safeguards as it meets in Garden Grove, Calif., this week.
At the meeting, these West coast fishery leaders should decide to prohibit new commercial fishing on saury ? a key forage fish ? until it can be shown that it won?t harm bigger fish, whales, and seabirds that depend on saury as a food source. Doing so will enable the council to ask important questions before US forage fishing begins rather than waiting until industrial-scale fishing boats are catching these important fish.
Internationally, these forage fish ? including sardines, anchovies, and saury ? already account for more than a third of the total catch of wild marine fish, with 90 percent of it processed into fish meal or oil.
To its credit, the council unanimously adopted a fishery ecosystem plan that begins to consider how everything is connected in the ocean. The plan?s top priority is to make sure that no new fishing begins on forage species without first evaluating the effect on the larger ecosystem and on other predator fish such as salmon, tuna, and lingcod.
Forage fish eat tiny plants and animals drifting on the ocean?s surface and, in turn, become a crucial food source for whales, seabirds, and bigger fish. Diminishing forage fish populations can have serious consequences for the larger ecosystem. Just this year, wildlife rehabilitation centers in California have treated more than 1,500 emaciated and dehydrated sea lion pups at a time when prey fish were scarce.
Pacific saury is exactly the type of currently un-fished forage species that the council?s new ecosystem plan intends to protect. This dart-shaped fish makes up as much as 78 percent of the diet of the sooty shearwater, a type of seabird that is now arriving by the millions along the California shore from breeding grounds near Chile and New Zealand.
We know that saury is already extensively fished elsewhere around the world, and its relatively high abundance makes it a potential target for fishermen here on the West Coast. As it stands, fishing could begin on saury at any time with no restrictions ? and no consideration of how it would affect predators. That would be a mistake. It is one the Pacific Fishery Management Council can ? and should ? avoid by approving restrictions on forage fishing at its meeting this week.
In April, the Pacific fishery council?s chairman cited the strong public testimony of the seafood industry, birding community, scientists, and fishermen in adopting a meaningful ecosystem plan. Protecting saury would help to maintain a productive ocean along the Pacific coast while demonstrating that regional fishery managers are serious about moving ecosystem-based management from theory into practice.
Some may wonder why we should act now. After all, no one on the West Coast is currently fishing for forage fish like Pacific saury, sandlance, or various kinds of smelts. To answer this concern, it?s worth looking north to Alaska. North Pacific fishery managers proactively protected dozens of unfished forage species more than a decade ago with the strong support of commercial fishermen. As one industry organization noted at the time, fishing for predators and their prey is akin to burning a candle at both ends.
I've been fishing almost as long as I can remember. Yet the thrill of being out on the water with friends, and the rush when a salmon or tuna bends my fishing rod, will never grow old.
It?s time for regional managers on the Pacific coast and elsewhere in the country to acknowledge what those of us on the water already know: Little fish are a big deal. It?s time to protect them.
Paul Shively works to conserve West coast forage fish as manager of the Pacific Fish Conservation Program at The Pew Charitable Trusts. He is a lifelong angler.
Most of us will never build our own car from scratch. Hell, most of us can't even hack together Ikea furniture. Understanding that, Toyota has built a prototype for the Camatte57s, a car you assemble yourself very easily, apparently.
Get this?the compact three seater is supposedly so simple to cobble together, you could do it with your kids. Oh, and your kids should be able to drive the thing too. Because it's actually sort of a toy. But it's the kind of toy that doesn't look like a toy. It's like the set of Hot Wheels you never had.
Toyota designed the Camatte57s with pedals and seats that can be adjusted to their little legs. Meanwhile, an adult can still fit in the right rear seat supervising. The good news about a car that kids can drive, they can't drive it on the street because, well, it's a toy. Some assembly required. [Toyota via RocketNews via DesignTaxi]
Full complement of Sky Android apps available once again after recent hack by Syrian Electronic Army
A quick heads-up for Sky subscribers in the UK -- the satellite broadcaster's range of Android apps has returned to the Play Store today following its Google Play account being hacked. The hack occurred over the weekend and was attributed to the Syrian Electronic Army, whose banners appeared on the apps' Play Store listings.
In the wake of the attack, Sky's apps were pulled from Google's app store, however the broadcaster has insisted that the apps themselves were not changed. As of this morning the full suite of Sky apps is once again available, including Sky News, Sky Sports, Sky+ and Sky Go. Sky subscribers can click here to view a full list of apps.
