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,

"Plastic is produced in large amounts and used for various purposes. After use, huge amounts end up in the enviroment, often in the oceans. There, fragmentation leads to small particles, called microplastics. By filtrating and benthos-feeding organisms it can be inadvertently taken up as food. We demonstrate that the unicellular ciliate Paramecium, the freshwater flea Daphnia and the blue mussel Mytilus took up microplastic particles. Even more, in Mytilus, the plastic particles were transported into the digestive gland and accumulated in the respective cells. Subsequently, pathological alterations in the gland were noted. Microplastics are of concern because animals might starve with a full belly after uptaking large amounts of microplastics. As well, particles with sharp edges can injure the mucous layer of the gastrointestinal tract. Furthermore, persistent organic pollutants adhere at plastic and thus, may cause adverse impacts on the animal. We show options for solutions and indicate selected organisations working on the development of solution"

"A team of scientists at Oxford University have printed - yes, printed - what could be the predecessors to usable synthetic human tissue. The researchers released a paper called A Tissue-Like Material, announcing that they created their own version of a 3D printer, saying the current ones on the market couldn't print what they were after, according to PhsyOrg. And what were they after? A protein sack of water that can mold itself into different shapes and perform similar functions to human cells. After developing the printer, the team was able to print out a series of droplets that formed a network of human-like cells that could act like nerves and send electrical signals across the network."

"People swap bacteria all the time-through sneezes and coughs, through hugs and sex, or through touching the same surfaces. Then there are people who swap bacteria because a doctor deliberately transplants faeces from one into the other. This isn't a bizarre medical perversion. It's usually a life-saving gambit. Faecal transplants-which are exactly what they sound like-are used to treat people who suffer from intense diarrhoea following rounds of antibiotics. The goal is simple: recalibrate the beneficial bacteria in a person's gut to fight off the ones that are causing them harm."

"I visit a lot of molecular biology labs, and most of them look pretty much identical: lab benches, microscopes, computers, messy break rooms, big filing cabinets crammed into every free corner. When you look closely, though, every lab has its own flavor, its own culture. This is the first post of what I hope will be a fun, photo-heavy series on the culture of different labs. Florian Engert's lab at Harvard is large, colorful, and messy."

"After many centuries of splints and cumbersome plaster casts that have been the itchy and smelly bane of millions of children, adults and the aged alike, the world over, we at last bring fracture support into the 21st century. The Cortex exoskeletal cast provides a highly technical and trauma zone localized support system that is fully ventilated, super light, shower friendly, hygienic, recyclable and stylish."

"The ArticuLab's mission is to study human interaction in social and cultural contexts as the input into computational systems that in turn help us to better understand human interaction, and to improve and support human capabilities in areas that really matter."

"In2Care is a private limited company registered and based in the Netherlands. Founded and privately owned by three leading entomologists, a serial entrepreneur and a chief commercial officer, In2Care has more than 30 years of combined research experience in vector control. Our core expertise lies in the translation of scientific knowledge into novel insect control products. We offer low-cost, proven, primarily biological solutions to combat disease-carrying mosquitoes"

'The Named Data Networking (NDN) project aims to develop a new Internet architecture that can capitalize on strengths - and address weaknesses - of the Internet's current host-based, point-to-point communication architecture in order to naturally accommodate emerging patterns of communication. By naming data instead of their locations, NDN transforms data into a first-class entity. The current Internet secures the data container. NDN secures the contents, a design choice that decouples trust in data from trust in hosts, enabling several radically scalable communication mechanisms such as automatic caching to optimize bandwidth.'

"Explore simultaneously in space and time with Time Machine Each Time Machine on this page captures a process in extreme detail over space and time, with billions of pixels of explorable resolution. Choose a time machine and zoom into the image while traveling backwards or forwards through time. Select a Time Warp and the time machine's authors will take you on a guided space-time tour with text annotations explaining what you are viewing. You can even learn how to create your own Time Machines and Warps."

Planetary Resources is establishing a new paradigm for resource discovery and utilization that will bring the solar system into humanity's sphere of influence. Our technical principals boast extensive experience in all phases of robotic space missions, from designing and building, to testing and operating.

The Haiti Memory Project is an  oral history project about the January 12, 2010, earthquake and post-earthquake life. The earthquake is a point-zero in the lives of individual Haitians and in Haitian history; it is a moment that divided time into "before" and "after". The project attempts to document that change.

"So-called jumping genes, segments of DNA that can copy and paste them­selves into new places in the genome, can alter the activity of full-length genes. Occasionally they will turn on neighboring genes in these locations. That activity occurs more in the brain than other areas, resulting in different traits and behaviors, even in closely related individuals. These mobile genetic elements may also turn out to play a role in people's disposition to psychiatric disorders"

Powerful and extensible JS data grid and explorer built on Backbone. Recline combines a data grid, Google Refine-style data transforms and visualizations all in lightweight javascript and html. Designed for standalone use or as a library to integrate into your own app. Recline builds on the powerful but lightweight Backbone framework making it extremely easy to extend and adapt and its modular design means you only have to take what you need.

"Rather, these successful men needed to also be blessed with "zeal and with capacity for hard labour." This study is a first glimpse into those essential qualities described by Galton, helping us map out the individual differences that make it slightly easier for some people to engage in hard labor. These diligent souls seem to get a bit more pleasure from the possibility of reward, but they also seem less sensitive to their inner complainer, that disruptive voice reminding them that minesweeper is more fun than editing, or that the ballgame on television is much more entertaining than their homework. At any given moment, there is a tug of war unfolding in our head, determining whether or not we're willing to put in the effort. This sentence only exists because, for a few minutes at least, I was able to win the war."

ai-one™ - biologically inspired intelligence. We sell software development kits (SDKs) for machine learning applications. We give programmers a virtual brain so they can build artificial intelligence into any software application. Unlike other machine learning tools, our technology works in any language, works with any data and learns quickly without human intervention.

"The project was kick-started by a huge public response to the team's research into the genetics of gut bacteria. In a previous study the researchers found that certain gut-specific genetic markers were related to obesity and other diseases. "I got between 50 and 100 e-mails from regular people having problems with the stomach or diarrhoea and wondering if we can help them," Peer Bork, a biochemist and co-creator of MyMicrobes, told Nature. This new website will build on that work, whilst also providing support for concerned members of the public."
