The now-settled lawsuits brought by thousands of former players hinged on the notion that the NFL ignored decades of research on the degenerative long-term effects of brain trauma, and didn't take enough steps to protect its employees.
The Zooniverse is home to the internet's largest, most popular and most successful citizen science projects. Our current projects are here but plenty more are on the way. If you're new to the Zooniverse, we suggest picking a project and diving in - the same account will get you into all of our projects, and you can keep track of what you've contributed by watching 'My Zooniverse'.
The Zooniverse began with a single project, Galaxy Zoo , which was launched in July 2007. The Galaxy Zoo team had expected a fairly quiet life, but were overwhelmed and overawed by the response to the project. Once they'd recovered from their server buckling under the strain, they set about planning the future!
Galaxy Zoo was important because not only was it incredibly popular, but it produced many unique scientific results, ranging from individual, serendipitous discoveries to those using classifications that depend on the input of everyone who's visited the site. This commitment to producing real research - so that you know that we're not wasting your time - is at the heart of everything we do.

It was amazing how quickly the new Quench classifications were completed. We posted them on Friday and you were already done by Sunday morning. Wow, that’s awesome! This means we can turn our full attention to making sense of the data. And we need your help!
In Part 1 of this How-To-Guide to data analysis within Quench, you learned how to use Tools, our analysis platform, and were inspired (or so I hope) about ways to play with the data as you read the background literature about post-quenched galaxies and galaxy evolution.
In Part 2 of this How-To-Guide, we’re going to help you navigate using Toolsto compare results from galaxies *you* classified with the rest of the post-quenched galaxy sample.
You’re 12 small steps away from your first comparison plot between your galaxies and the full sample… let’s get started!
Step 1: Enter Tools and log in using your Zooniverse login information.
Step 2: Choose ‘Quench’ in the pull-down menu in the upper-left, next to the words ‘zootools’. Now click ‘Create Dashboard*’ in the upper-right, and give it a name, like: ‘My Data in Context’.
Step 3: Click ‘Data’ in the upper-left and choose ‘Zooniverse’ in the pop-up options.
Step 4: In the window that pops up, choose ‘Recents’ or ‘Collections’. Your choice.
If you classified galaxies in quench.galaxyzoo.org, they’ll be accessible through ‘Recents’. Choose the max number possible. If you created a Collection of interesting galaxies in Quench Talk or want to look at someone else’s Collection, you can access them by clicking ‘Collections’.
I’ve created a Dashboard* in Tools called ‘Example: My Data in Context’. Take a look and, if you’d like, you can even make edits by copying it into your Tools environment.
Huge variety of Space gear for sale from clothing to art, to meteorites and books on space.
Geoff Notkin teams up with Deep Space by Design to offer select Meteorites
Described by the media as “one of the rock stars of science,” Geoff Notkin hosts Science Channel’s award-winning adventure series Meteorite Men. He is also an internationally recognized authority on meteorites, an award-winning author and photographer, a musician, world traveler, and adventurer. Geoff is the owner of Aerolite Meteorites LLC, a leader in meteorite recovery and research.
A major figure in meteorite studies, Geoff has found space rocks on four continents and worked with the world’s top institutions. His company, Aerolite Meteorites LLC, provides meteorite specimens to researchers and collectors worldwide. The minor planet 139204, discovered at Mount Palomar, was named after Geoff in recognition of his contributions to science and education.
A long-term study finds extremely low incidence of cancer and diabetes among individuals with a growth-stunting genetic defect. The authors ask whether controlling growth hormone in healthy adults might provide similar protection.
Many uncontacted tribes still exist. Where are they, and why do they occasionally reach out to the rest of the world? How many uncontacted tribes are still left? No one knows for sure. At a rough guess, there are probably more than 100 around the world, mostly in Amazonia and New Guinea, says Rebecca Spooner, of Survival International, a London-based organisation that advocates for the rights of indigenous peoples. Brazil's count is likely to be the most accurate. The government there has identified 77 uncontacted tribes through aerial surveys, and by talking to more Westernised indigenous groups about their neighbours.
There are thought to be around 15 uncontacted tribes in Peru, a handful in other Amazonian countries, a few dozen in the Indonesian part of the island of New Guinea and two tribes in the Andaman Islands off the coast of India. There may also be some in Malaysia and central Africa.
Have they really had no contact with the outside world? Most have had a little, at least indirectly. "There's always some contact with other isolated tribes, which have contact with other indigenous people, which in turn have contact with the outside world," says Spooner.
Many of the Amazon tribes choose to avoid contact with outsiders because they have had unpleasant encounters in the past. The Mashco-Piro, for example, abandoned their settled gardens and fled into the forest. According to Glenn Shepard, an ethnologist at the Emilio Goeldi Museum in Belem, Brazil, this came after rubber companies massacred tribespeople at the turn of the 20th century. For this reason, some researchers refer to such tribes as "voluntarily isolated", rather than uncontacted.
More recent incursions, especially by miners, oil workers and loggers, may have reinforced the tribes' xenophobia. In 1995, oilfields were encroaching on the homeland of the uncontacted Huaorani people of eastern Peru. A visiting reporter was warned that any unclothed native should be regarded as uncontacted and, thus, very dangerous.
Are there guidelines for how best to approach such tribes? In Peru, laws prohibit outsiders from initiating contact with isolated groups in most cases. They also provide protected areas where tribes can live in peace – but there are loopholes that allow oil and mining companies into the region. Brazil has similar laws and policies that allow contact only in life-threatening situations.
Anthropologists have an ethical obligation to do no harm to their research subjects, according to the American Anthropological Association's Statement on Ethics. However, they are rarely the first people to make contact with indigenous groups – missionaries and resource developers almost always get there first, says Kim Hill, an anthropologist at Arizona State University who has worked with several recently contacted tribes. As a result, there is no standard practice for initial contact, he says.
'The latest findings from the real neuroscience of creativity suggest that the right brain/left brain distinction is not the right one when it comes to understanding how creativity is implemented in the brain.
A joint study from the U.S. Geological Survey and the U.S. Fish and Wildlife Service released Wednesday found that a fracking fluid spill in Kentucky in 2007 likely caused the widespread death of several types of fish.
