Messenger RNA vaccines

-

 


We got very lucky. The two most effective vaccines against the coronavirus are based on messenger RNA, a technology that has been in the works for 20 years. When the covid-19 pandemic began last January, scientists at several biotech companies were quick to turn to mRNA as a way to create potential vaccines; in late December 2020, at a time when more than 1.5 million had died from covid-19 worldwide, the vaccines were approved in the US, marking the beginning of the end of the pandemic.

The new covid vaccines are based on a technology never before used in therapeutics, and it could transform medicine, leading to vaccines against various infectious diseases, including malaria. And if this coronavirus keeps mutating, mRNA vaccines can be easily and quickly modified. Messenger RNA also holds great promise as the basis for cheap gene fixes to sickle-cell disease and HIV. Also in the works: using mRNA to help the body fight off cancers.

Computer Basics-Basic Parts of a Computer

-
Introduction The basic parts of a desktop computer are the computer case, monitor, keyboard, mouse, and power cord. Each part plays an important role whenever you use a computer. The computer case is the metal and plastic box that contains the main components of the computer, including the motherboard, central processing unit (CPU), and power supply. The front of the case usually has an On/Off button and one or more optical drives. Computer cases come in different shapes and sizes. A desktop case lies flat on a desk, and the monitor usually sits on top of it. A tower case is tall and sits next to the monitor or on the floor. All-in-one computers come with the internal components built into the monitor, which eliminates the need for a separate case. Monitor The monitor works with a video card, located inside the computer case, to display images and text on the screen. Most monitors have control buttons that allow you to change your monitor's display settings, and some monitors also...

हमारे बच्‍चों का मनोविज्ञान बड़ों की पकड़ से हर दिन दूर होता जा रहा है. ऐसा लगता है, मानो पेड़ धीरे-धीरे जड़ से ही दूर हो रहा है.   दयाशंकर मिश्र   |  Updated: Mar 30, 2018, 08:01 AM IST सुनने में बात थोड़ी अटपटी लग सकती है. इसमें नया क्‍या है. सब अपने से प्रेम करते हैं. कुछ तो अपने से प्रेम में डूबे रहते हैं. लेकिन ज़रा ठहकर सोचिए. अब यह बातें कुछ पुरानी सी लगने लगी हैं. हमारे विचार, चिंतन शैली पर सुकून से अधिक बाज़ार/ज़रूरतें हावी होती जा रही हैं. आप अपने किसी भी नज़दीकी को सैंपल के तौर पर चुन लीजिए. बहुत नहीं उनसे केवल तीन-तीन महीने के अंतर पर बात करते रहिए. आप आसानी से समझ जाएंगे कि उनकी चिंतन प्रक्रिया का केंद्र निरंतर बदल रहा है. इस बदलाव में उनका अंतर्मन कहीं नहीं है. जीवन की गुणवत्‍ता कहीं नहीं है. सारा ज़ोर बस इस बात पर दिखेगा कि मेरे पास क्‍या है? हमारे बच्‍चों का मनोविज्ञान बड़ों की पकड़ से हर दिन दूर होता जा रहा है. ऐसा लगता है, मानो पेड़ धीरे-धीरे जड़ से ही दूर हो रहा है. हमारे एक मित्र हैं. दूसरों से ख़ूब बातें करते हैं. बेइंतहा बातें. बातें ही बातें....

Hyper-accurate positioning

-
  We all use GPS every day; it has transformed our lives and many of our businesses. But while today’s GPS is accurate to within 5 to 10 meters, new hyper-accurate positioning technologies have accuracies within a few centimeters or millimeters. That’s opening up new possibilities, from landslide warnings to delivery robots and self-driving cars that can safely navigate streets. China’s BeiDou (Big Dipper) global navigation system was completed in June 2020 and is part of what’s making all this possible. It provides positioning accuracy of 1.5 to two meters to anyone in the world. Using ground-based augmentation, it can get down to millimeter-level accuracy. Meanwhile, GPS, which has been around since the early 1990s, is getting an upgrade: four new satellites for GPS III launched in November and more are expected in orbit by 2023.
