By Brandon Specktor, Senior Writer 2 October 2018 Scientists in the United Kingdom have turned to the humble human sperm in their quest to design the ultimate swimming robot. Made of a tiny magnetic head and squiggly elastic tail, the flea-size drones look and swim … Continue reading Tiny Robots Inspired by Sperm Want to Swim Around Your Body Delivering Drugs
The ancient, arid landscapes of Australia are fertile ground for new growth, says Douglas MacFarlane, a chemist at Monash University in suburban Melbourne: vast forests of windmills and solar panels. More sunlight per square meter strikes the country than just about any other, and powerful winds buffet its south and west coasts. All told, Australia boasts a renewable energy potential of 25,000 gigawatts, one of … Continue reading Liquid Sunshine
हम इस लेख के विकिपीडिया पर मूल अनुवादक है। काण्टीय नीतिशास्त्र का सन्दर्भ एक कर्तव्यवैज्ञानिक नीतिशास्त्रीय सिद्धान्त(deontological ethical theory) से हैं, जिसको जर्मन दार्शनिक इमानुएल काण्ट ने प्रस्तुत किया था। यह सिद्धांत यूरोपीय ज्ञानोदय युग( 18 वी सदी) के परिणाम स्वरुप विकसित हुआ था, यह इस दृष्टिकोण पर आधारित है कि आंतरिक रूप से एक शुभ संकल्प ही शुभ कार्य है; एक कार्य केवल तभी … Continue reading काण्टीय नीतिशास्त्र
Researchers have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power. Directly converting electrical power to heat is easy. It regularly happens in your toaster, that is, if you make toast regularly. The opposite, converting heat into electrical power, isn’t so easy. Researchers from Sandia National Laboratories have developed a tiny silicon-based device that … Continue reading Generating electrical power from waste heat
विज्ञान की विस्मयकारी प्रगति विश्व-भर के कर्मठ वैज्ञानिकों के सामूहिक प्रयास का प्रतिफल है। यह सर्वविदित है कि विज्ञान की दृष्टि से प्राचीन भारत की उपलब्धियां विस्मयकारी थीं। परन्तु ऐसा देखा गया है कि वर्तमान में जब भी प्राचीन भारतीय विज्ञान की चर्चा होती है, तो भारतीय जनमानस दो गुटों में विभाजित हो जाते हैं। एक गुट के अनुसार हमारे पूर्वजों ने प्राचीन काल में … Continue reading प्राचीन भारत में वैज्ञानिक दृष्टि
Many people suffer from injuries that often don’t show any visible signs of damage. Certain chronic diseases and traumas can lead to massive internal bleeding, which typically require surgical intervention in order to get fixed. Now a group of researchers has developed a method to effectively put an end to internal bleedingwhenever it occurs, and they did it through the use of magnetic nanoparticles. Magnetic nanoparticles … Continue reading Magnetic nanoparticles seen as effective material for stopping internal bleeding
Don’t let the word love define your LOVE Love is the most powerful emotion a human being can experience. The strange think is, that almost nobody knows what love is. Why is it so difficult to find love? That is easy to understand, if you know that the word “love” is not the same as one’s feeling of love. The word “love” is used and … Continue reading What Is Love? A Philosophy of Life
There is something very distinct about the air over India and the surrounding countries in South Asia. It is the presence of formaldehyde – a colourless gas that is naturally released by vegetation but also from a number of polluting activities. The elevated concentrations have been observed by Europe’s new Sentinel-5P satellite, which was launched last October to track air quality worldwide. It is information … Continue reading Why does India’s air look different from space?
When severe, chronic diarrhea strikes, sometimes the only cure is … more feces. It might seem bizarre, but a transplant of healthy human stool and its bacterial ecosystem can mean freedom from a painful, life-threatening illness. The transplants — called fecal microbiota transplants, or FMTs — are becoming more and more popular. So popular that the stool bank OpenBiome has supplied more than 30,000 stool … Continue reading To regulate fecal transplants, FDA has to first answer a serious question: What is poop?
Alligators don’t just stick to freshwater and the prey they find there. These crafty reptiles can live quite easily, at least for a bit, in salty waters and find plenty to eat — including crabs, sea turtles and even sharks. “They should change the textbooks,” says James Nifong, an ecologist with the Kansas Cooperative Fish and Wildlife Research Unit at Kansas State University in … Continue reading WILD THINGS ANIMALS Alligators eat sharks — and a whole lot more
