மும்பை ஐஐடி மற்றும் இந்திய ரயில்வே ஆராய்ச்சியாளர்கள், ரயில்வேயின் செயல்திறனை மேலும் அதிகரிக்க, வாரத்தின் சில நாட்களில் மட்டுமே இயக்கப்படும் ரயில்களை ஒரே குழுவாக இணைத்து, திட்டமிடலில் ஒரு புதிய மாற்றத்தைக் கொண்டுவந்துள்ளனர்
Coacervation is a phenomenon where in two liquids that are mixed together, driven by the difference in the electrostatic charge of the different molecules of the two liquids, separate out into two layers.
The Gravity Recovery and Climate Experiment (GRACE), a joint mission of NASA and German Aerospace Center, was launched in 2002 and has been making a detailed map of earth’s gravity field anomalies. By studying these anomalies, one can show how mass is distributed on the planet’s surface.
Space missions come with an unprecedented excitement of open a Pandora’s box of unknown facts, mysteries and phenomenons. It is hardly a surprise that New Horizons, NASA’s mission to explore Pluto and beyond has caused a great excitement in the field of planetary science. Launched in 2006, New Horizons has already provided mankind with the most intimate images of Pluto till date and is now cruising towards the Kuiper Belt beyond our Solar System. Read all that you should know about this space mission, its latest findings and its future stops as it progresses toward new horizons of space in an interview with Prof. Henry Throop.
Tigers, a well-known member of the cat family and India’s national animal is unique in many ways. Once found abundantly in the tropics of Asia, tigers today have little to call home or family. Their numbers have seen a sharp fall in the recent years, thanks to habitat destruction and poaching. While conservation efforts are on to protect this endangered species, there is still a long way to go before these shy cats can roam the jungles as kings. Today, on the event of International Tiger Day, here is a snapshot on what’s troubling them and how we know about it.
Biofuels are fuels produced through biological processes, like those derived from plant and microbes. Unlike the fossil fuels which are formed by geological processes, over millions of years, Biofuels can be produced from regular plant material, making it an excellent substitute for fossil fuels.
Each monsoon brings a fury of rains in different parts of the country killing many people and damaging properties. In spite of having disaster warnings in place, India still battles floods and the rains as many of us watch helplessly. But perhaps no more, thanks to science! Researchers have now developed a new technique to forecast extreme rainfall events by considering regional parameters that affect the quantity of precipitation. This model, which is accurate than existing models used to forecast rains, can be used for any region by including regional parameters like temperature and humidity, say the researchers.
Today, India’s space programs command the world’s respect for a multitude of things -- our Mangalyaan mission was the cheapest ever, we recently launched about 108 satellites into space with a single rocket, our Chandrayaan mission is making fantastic discoveries on the Moon, we launched our own space based observatory with Astrosat...the list goes on. But when the country started its space program, it had very humble beginnings that are hard to believe. It required the courage and determination of many intellectuals and Prof. U R Rao is one of those who scripted a new chapter in India’s history of space research. Here is an orbituary piece dedicated to the life of a great visionary that we just lost amongst us.
A rising population demands an upgrade to the infrastructure of towns and cities, failing which congestion and traffic jams become unavoidable. The situation is improved with efficient allocation of resources and infrastructure, usually achieved with the help of computer simulations.
The mangrove ecosystem is a fragile ecosystem found in the tropical and subtropical sea shores and houses a variety of plants and animals. Some of these have evolved special adaptation techniques to thrive in the salt-rich low-in-oxygen soil, and have supported human communities around the forests. Today, on the occasion of the ‘International Day for the conservation of the mangrove ecosystem, here is a snapshot of the importance of mangroves and why conserving them is the need of the hour today.
Hepatits C, caused by the hepatitis C virus (HCV), is an infectious disease affecting over 140 million people around the world. The virus spreads by blood to blood contact, affecting the liver and causing infections, which if left untreated could lead to cancer.
