Chimpanzees (Pan troglodytes) appear to keep tidier sleeping arrangements than humans do. That’s one finding of a recent study that evaluated the microbes and arthropods found in the treetop beds that chimpanzees make each night.
How to spot the secretive activities of rogue fishing boats
The next time you cook a fish or order some seafood at a restaurant, think about the image above.
It’s a snapshot of all the fishing happening on the ocean over a six-month period. If you zoomed in, you’d see thousands of blue dots, each showing one instance of likely fishing activity at one point in time. This image captures almost 20 million hours of commercial fishing by tens of thousands of vessels around the world. As we approach World Oceans Day this week, it’s sobering to reflect on the fact that industrial fishing now occurs in more than 55% of the ocean – an area more than four times bigger than all the land used for farming.
Eastern European Association of the Greens supported Greenpeace initiative to create an Antarctic Ocean Sanctuary
June, 19, in Frankfurt, Germany, Greenpeace held an action to collect signatures in order to save the Antarctic and make it Sanctuary. President of Eastern European Association of the Greens Alexander Kamenets joined the colleagues and supported their initiative.
Gas Turbine Engine, How it Works ?
This video lecture describes working of gas turbines in a conceptual way. Here we will go through how gas turbines produce propulsive power in a jet engine aircraft, by executing Brayton cycle.
How do Wind Turbines work ?
Working of a wind turbine is illustrated in this video with the help of animation. The topic covered are blade design, use of brake, velocity sensor, yawing mechanism, blade tilting, wind turbine efficiency and Betz’s limit.
Ecovillage
Ecovillages are traditional or intentional communities whose goal is to become more socially, culturally, economically and ecologically sustainable. Ecovillages are consciously designed through locally owned, participatory processes to regenerate and restore their social and natural environments. Most range from a population of 50 to 150 individuals, although some are smaller, and traditional ecovillages are often much larger. Larger ecovillages often exist as networks of smaller subcommunities. Certain ecovillages have grown by the addition of individuals, families, or other small groups who are not necessarily members settling on the periphery of the ecovillage and effectively participating in the ecovillage community.
Plastic and other waste found in British mussels
Researchers have found tiny pieces of plastic in all the samples of mussels they tested in British seawaters and bought from local supermarkets.
The scientists, from the University of Hull and Brunel University, said the contamination from microplastics and other human debris, such as cotton and rayon, was significant and widespread.
Deadly fungus found for first time in critically endangered amphibian species
A fungal pathogen which has led to the extinction of entire species in South America has been recorded for the first time in critically endangered amphibians in India. Batrachochytrium dendrobatidis (Bd) can cause the lethal disease chytridiomycosis, and is considered a significant threat wherever it is found.
How does a Thermal power plant work ?
The operation of a thermal power plant is explained in a logical manner with help of animation in this video. Starting from the very basic question a conceptual overview of Rankine cycle is provided here. Topics such a Generator, Steam turbine, condenser, feed water pump, boiler are illustrated initially. The basic Rankine cycle is modified and use of super hearing, reheating and feed water heating (deaerator) is explained there after.
What is Solar Energy?
The consumption of non-renewable sources like oil, gas and coal is increasing at an alarming rate. The time has finally come to look after some other renewable sources of energy i.e. solar, wind and geothermal energy. Although many countries have started utilizing solar energy extensively but still they have to go a long way to exploit this energy to fulfill their daily demand for energy. Here are few facts on solar energy that can help you assess the potential of solar energy to meet global requirements.
