The red planet had fresh water puddle on its surface around 4 billion years ago, as revealed by NASA Mars Opportunity Rover upon analyzing some of the oldest minerals. The same facts have been confirmed by the Curiosity, the newcomer collecting data on the other side of the planet. Planetary scientist Ray Arvidson, with Washington University in St. Louis said,the pool of water was so fresh that could have sustained all life forms.

Travelling to space can have an adverse effect on the immune system. Researchers at University of California Davis College of Biological Sciences and lead by Deborah Kimbrell, found that the fruit flies (Drosophila flies) born and raised in a spacecraft has weak immune system in fighting commonly occurring fungus. The researchers choose Drosophila flies for the fact that they share many basic features of their defense mechanism with those of mice and humans.

Paper coming from wood fibers would now be replacing plastic substrates that are employed in the manufacturing solar cells. Researchers from University of Maryland, the South China University of Technology, and the University of Nebraska-Lincoln have proposed this evolutionary step towards future technology. As per the researchers, solar cells gives maximum output when the materials involve have high optical transparency and high optical haze. Diffusion of light is of high quality when the optical transparency is high. And high optical haze helps in increasing the scattering of light which further…

The grey matter of the brain is a major component of the central nervous system which includes regions of the brain involved in muscle control, sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control- Wikipedia. While grey matter is known to include “regions of the brain involved in muscle control, sensory perception such as seeing and hearing, memory, emotions, speech, decision making, and self-control”-Wikipedia, it is now thought to be involved in our sense of pain. A recent study conducted by scientists at Wake Forest…

Black widow spiders, as the name suggest are famous for their sexual cannibalism, a practice where the female eats its partner soon after mating process ends. The venom of the female spiders is three times stronger, making the poor male defenseless. These facts have made scientists curious to know, how does the male approaches female for the mating without being confused for prey.

Good news for all the coffee lovers! Until now, our favorite cup of coffee was helping us to stay alert. Now researchers from the Johns Hopkins University have found coffee could actually act as memory enhancer. Assistant professor of psychological and brain sciences, Michael Yassa and his team revealed that caffeine has an encouraging outcome on deep rooted memory in humans and up to 24 hours after its consumption, certain memories can be very well retained.

Many species of birds have been flying in a V shaped formation. Reason behind this formation was not known and was thought to be helping birds save energy during their journeys. This V formation was typical for certain species of migratory birds such as cranes, pelicans, ibises and geese flying for thousands of kilometers, saving energy while flying would make huge difference for these birds.

Spider’s spun web to trap insects, which is known for its tensile strength and flexibility, easily stretching up-to five times their length without breaking. These webs, trap flying insects, pollen’s and other particulate matter present in the air. Traditionally it was believed that the flying insects are caught in this web. Interestingly, it is recently discovered that the spiders web are coated with a glue which makes the web electrically charged and so the web can actually leap towards any charged particles to grab it. The glue-coated web can even…

Global warming is melting the ice from the glaciers hence increasing the sea level and posing a serious threat for cities and towns situated along the coast. Based on the topic a team of scientist found that the Antarctica’s Pine Island Glacier which is considered as the single major contributor for the rise in the world sea level, is melting continuously year after year and is believed to contribute nearly a centimetre (0.4 inches) rise in sea level in the coming 20 years. Recession of the ice sheets seem irreversible…
