वर्षको एकदिन मात्र फुल्ने अनौठो फूल

वर्षको एकदिनमात्र फूल फुल्छ भन्ने सुन्दा अचम्म लाग्छ तर यो सत्य हो। पूर्वपश्चिम राजमार्गखण्डअन्तर्गत छिमेकी जिल्ला सिरहाको पडरिया चौकदेखि दक्षिणमा रहेको ऐतिहासिक तथा प्राचीन राजा फूलबारीमा यस्तै फूल देख्न पाइन्छ। सलहेस फूलबारीको नाउँले प्रसिद्ध रहेेको यो ऐतिहासिक फूलबारीमा प्रत्येक नयाँवर्षका दिन त्यहाँ रहेको हारमको रुखमा सुनाखरी आकारको फूल फुल्छ र साँझपख मौलाएर जान्छ।

Charge your smartphone battery in 30 second

A two-year-old Israeli startup, StoreDot, thinks it has cracked the problems of limited battery life with a smartphone battery made of biological structures that can recharge in around 30 seconds. The battery is currently only a prototype and the firm predicts it will take three years to become a commercially viable product.In the demonstration, a battery pack the size of a cigarette packet was attached to a smartphone. “We think we can integrate a battery into a smartphone within a year and have a commercially ready device in three years,” founder Dr Dorn Myersdorf told.

The Heartbleed Bug

Security vulnerabilities come and go, but this one is extremely serious. Heartbleed can reveal the contents of a server’s memory, where the most sensitive of data is stored. That includes private data such as usernames, passwords, and credit card numbers. It also means an attacker can get copies of a server’s digital keys then use that to impersonate servers or to decrypt communications from the past or potentially the future, too.

NIST’s new atomic clock won’t lose a second for 300 million years

New clock NIST F2 is three times more accurate than previous atomic clock Nist F1. Like the F1, this clock uses the radioactive emissions of caesium atoms to measure and keep time. Unlike the F2, however, the previous best standard measured its samples at room temperature. By lowering the sample to a chilly -192 degrees Celsius, NIST was able to stop a lot of the small, confounding emissions that were muddying their readings.

Ford’s self-driving car unveils itself

Ford Motor unveiled its first self-driving car this week — well, a prototype anyway. The Automated Fusion Hybrid Research Vehicle, developed with the University of Michigan and State Farm insurers, will help the storied US automaker “test the limits of full automation and determine the appropriate levels for near- and mid-term deployment,” Raj Nair, group vice president, Ford global product development,said in a statement.

Why Is Dark Chocolate Good for You? Thank Your Microbes

Dark chocolate might pack a double positive punch for our health—thanks to the microbes that live in our gut. New research suggests that beneficial bacteria that reside toward the end of our digestive tract ferment both the antioxidants and the fiber in cocoa.In their deep-gut alchemy these microbes create anti-inflammatory compounds that have been linked to the cardiovascular and other benefits from dark chocolate consumption.

GDC: Intel Lays Out Plan to ‘Reinvent the Desktop’

Intel is also introducing something called Ready Mode Technology, Graff said. This is “a capability that takes advantage of new power-saving states in Intel’s 4th-generation Core desktop processor, combined with software and board level optimizations which enable OEM desktop computers that are instantly ready and always connected while sipping power,” according to the company.

See How the CPU Works In One Lesson (video)

A central processing unit (CPU) (formerly also referred to as a central processor unit) is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and input/output operations of the system. The form, design, and implementation of CPUs have changed over the course of their history, but their fundamental operation remains much the same.

Electric versus hydrogen: China is the battleground

Electric versus hydrogen? Which is the future? Fuel cell cars can run up to five times longer than regular all-electric counter parts, but come with a heftier price tag. But, unlike electric vehicles which can be recharged from home as well as charging stations, fuel cell cars must stop at refilling stations. The rush into all-electric cars comes as Beijing ramps up a program to put five million new energy vehicles – defined as all-electric battery vehicles and heavily electrified ‘near all electric’ plug-in hybrids, on the road by 2020.

self driving cars the future of transport explained

Reading a magazine while driving? Shouldn’t it be a Kindle? Humans can’t be trusted behind the wheel. They misjudge distances, drive aggressively, get distracted by other passengers, and many of them talk on the phone. Is it time to get rid of them and hand their driving licences over to the cars themselves?Google has sparked off the current interest in driverless cars. As well as having ambitions in the connected car sphere.

The History of the Lamborghini Gallardo

Back in 2003, Lamborghini has started to produce their most successful supercar ever, the Gallardo. After 8 years of production, over 12.000 Gallardos came out the Sant’Agata Bolognese factory making it the most-produced Lamborghini ever.

Porsche Panamera S E-Hybrid for 2014

In Porsche Panamera S E-Hybrid engineers married a supercharged V6 with a plug-in hybrid powertrain. The car’s three driving modes-electric, hybrid, and recharge give drivers the flexibility they need to scream down the highway and then flip to electric power for short-range cruising.Coupled to a familiar 3.0L supercharged V6 pumping out 333 hp and 325 lb-ft of torque the new powertrain makes a combined 416 hp and 435 lb-ft.

Lamborghini Veneno Roadster

The Lamborghini Veneno Roadster is an open racing prototype with an extreme design and breathtaking performance. And it is one of the world’s most exclusive automobiles – not more than nine units will be built during the course of 2014 and sold at a price of 3.3 million Euros (excl. tax).With a maximum output of 552 kW / 750 hp, the Veneno Roadster accelerates from 0 to 100 km/h in just 2.9 seconds and top speed stands at 355 km/h. The Lamborghini Veneno Roadster is driven by a twelve-cylinder engine with a displacement of 6.5 liters and is equipped with the extremely fast-shifting ISR transmission with five modes, permanent all-wheel drive and a racing chassis with pushrod suspension and horizontal spring/damper units.

Haswell

Intel’s new Haswell chips are here. The question is, should you care? As we’ll discover, the answer depends entirely on what you want from a PC. Haswell is a a new family of 22nm processors from Intel, still known as i3, i5 and i7 inside PCs and on the shelf. So has Intel succeeded again? As we’ll find out the answer is a bit of yes and no. Where Intel has failed us, those failures are entirely intentional.

How Camshaft Works

A camshaft is a shaft to which a cam is fastened or of which a cam forms an integral part. So how camshaft works? You know about the valves that let the air/fuel mixture into the engine and the exhaust out of the engine. The camshaft uses lobes (called cams) that push against the valves to open them as the camshaft rotates; springs on the valves return them to their closed position which allows air in and exhaust out.
