Researchers from Harvard University are using drones to better understand the Amazon rainforest. With drone-based sensors, the researchers hope to determine the unique “fingerprint” of different rainforest ecosystems. That could help them monitor the health of the forest and understand how it’s responding to climate change, deforestation and fire.
हिन्दी – एक वैज्ञानिक भाषा
Hindi -A scientific language.
हिंदी की जननी संस्कृत ने इसे विशेषताओं से भर दिया है । वाक्य के शब्दों को आगे पीछे करो, फिर भी अर्थ वही होता है । अर्थ वही होता है शब्दों को आगे पीछे करो । ना कैपिटल लेटर्स के झमेले ना स्माल लेटर की, ना एक्सेंट या ऊच्चारण सिखने की। ऐसी वैज्ञानिकता है हिंदी भाषा में।
कभी-कभी समय के प्रवाह में
बहते-बहते हम विचारों की
उस दुनिया में पहुँच जाते हैं,
जहाँ से लौटने में अपने को
जगाना पड़ता है……
फिर भी लौटने में वक़्त लगता है…
Color-changing smart skin is nothing new, but scientists have had a hard time working out the kinks. Current smart skin is fragile and buckles after being exposed to varying temperatures. To help remedy that problem, scientists turned to analyzing detailed videos of chameleons’ skin. This helped them develop a far more resilient take on this tech, which shows a more promising future for color-changing gear.
जिंदगी के किताब के पन्ने,
हवा के शरारती झोंके से,
फड़फड़ाते शोर मचाते पलटते देखा।
खूबसूरत नाजुक, लम्हे फिसलते देखा,
बेइंतहा इम्तिहानो से जिंदगी को गुजरते देखा,
जरूरत के वक्त रिश्तो को बदलते देखा,
पुराने फीके, पीले पन्नों जैसे फीके पङते यादों को जी कर देखा।
बस इतना ही समझ आया –
कभी समय नहीं गुजरता और कभी-कभी समय नहीं ठहरता।
और वक्त गुजरने में वक्त नहीं लगता।

The planet is located about 110 light-years away in the Leo constellation, according to a press releasefrom NASA about the exoplanet. NASA says K2-18b resides in a “habitable zone,” which is “the region around a star in which liquid water could potentially pool on the surface of a rocky planet.”
