Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton. The study found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

Within the ground beneath our feet lie dark cavities of various shapes and sizes. They're home to pale and eyeless creatures living a midnight existence. Natural holes in the ground, filled with air and/or water, can be roughly categorized into three types based on the particular habitat they provide for subterranean organisms:(1) Caves are large, deep, and tend not to contain much organic matter for organisms to munch on. They're often found in karst and volcanic areas prone to developing big h........ Read more »

Researchers at Arizona State University have demonstrated for the first time the mechanism by which antibacterial clays kill bacteria.

Thanks to the Internet, amateur volunteers known as "citizen scientists" can readily donate their time and effort to science--in fields ranging from medicine to zoology to astrophysics. The astrophysics project Space Warps offers a compelling example of why citizen science has become such a popular tool and how valuable it can be.

Clouds, particularly at night, have a huge role in the melting of Greenland ice sheet, whether these clouds have snow or liquid.
Researchers are working on Greenland ice sheet in order to know the reasons behind its melting, and now they have found the probable mechanism, i.e. clouds are involved in that melting.

Natural clay (such as Oregon Blue clay) can help in killing a broad range of bacterial pathogens including antibiotic resistant bacteria.

Gold is not considered a dietary micronutrient, and is the one of the most inert metals.

Swedish scientists have built a camera that makes methane gas visible. The tool could help researchers study greenhouses gases and answer tricky questions about climate change. It's also good for visualizing cow farts.
Magnus Gålfalk of Linköping University explains that the camera works using infrared spectroscopy. Called "hyperspectral imaging," the method simultaneously captures a spectrum of infrared light for every pixel in a photo. Many gases absorb infrared light, Gålfalk says, ........ Read more »

Scientists have suggested that we have more diamonds than we think, and the process of formation of diamond is probably not as complicated as we think.
In a recent study from scientists of Johns Hopkins University, it has been suggested that diamonds in the Earth are not as rare as once thought. They are of opinion that diamonds are commonly produced deep inside the Earth.
