KalamSat: World’s Lightest & Smallest Satellite

World's Lightest & Smallest Satellite

NASA scientists have been unable to create the smallest satellite ever until now.. Indians once again made history by designing and building world’s smallest and lightest satellite on behalf of ‘Space Kidz India’, a Research Organization based on Chennai for children. Kalamsat is the brainchild of Rifath Sharook, an 18-year-old boy, from Tamil Nadu’s Pallapatti town, India.  Others on the team include Tanishq Dwivedi (flight engineer), Vinay S Bhardwaj (design engineer), Yagna Sai (lead technician), Mohammed Abdul Kashif (lead engineer) and Gobi Nath (biologist). For the past four years, these young minds have been working on rocket and space technology under the mentorship of Chennai-based Srimathy Kesan, the founder and chief executive officer of Space Kidz India.

JUDY: Android Nightmare

Latest Android Nightmare

It seems that more malware threats are on the way. After Wannacry, a malware called Judy is infecting Android phones. “Judy” is an auto-clicking adware found on 41 apps developed by a Korean company, named Kiniwini, registered on Google Play, Google’s official app store, as ENISTUDIO corp. The company develops mobile apps for both Android and iOS platforms. The malware uses infected devices to generate large amounts of fraudulent clicks on advertisements, generating revenues for the perpetrators behind it. Continue reading “JUDY: Android Nightmare”

Disney’s Roomscale Wireless Charging..

Disney creates prototype living room with ubiquitous wireless power delivery

Wireless power is an idea that came into main stream ever since from 1891, when Nikola Testla demonstrated that you could transfer power between two objects via electromagnetic field. But it took over a century for the technology to find its own way, in the past few years wireless charging has finally emerged onto the consumer electronics market. But existing wireless charging is facing two challenges: range and health concerns. Safe, non-radiative methods such as near-field coupling are highly localized and require the devices to be placed near the charging source. It interrupts freedom and Charging is restricted to a confined area. Scientists at a branch of the Walt Disney Company called Disney Research have found a way to tackle these problems and charge devices on a room-scale without using any wires.

Hope You Don’t “Wanna Cry”

See all Insider WannaCry is a ransomware worm that spread rapidly through across a number of computer networks in May of 2017. After infecting a Windows computers, it encrypts files on the PC's hard drive, making them impossible for users to access, then demands a ransom payment in bitcoin in order to decrypt them.

“WannaCry” first discovered on Friday, May 12th2017, had spread to an estimated 57,000 computers in more than 150 different countries around the world by the end of the day. Some experts said the threat had receded as of Sunday, in part because “MalwareTech” registered a domain that he noticed the malware was trying to connect to, limiting Wanna Cry’s spread. Microsoft also issued emergency security patches for a range of Windows versions. But the Hackers updated the software to another variant which spreads more rapidly and creating more havoc. Infact, second variant doesn’t have a kill switch and is responsible for 50% of all attacks . Continue reading “Hope You Don’t “Wanna Cry””

BITCOIN, What is it actually???

bitcoin

As the Bitcoin is in news, Lets see what is it ?? Bitcoin is a digital currency also called crypto-currency which allows people to buy goods and services and exchange money without involving banks, credit card issuers or other third parties. Satoshi Nakamoto introduced the bitcoin protocol, publishing a paper via the Cryptography Mailing List in November 2008. But after all these years, he remain unknown. Whoever it is, it doesn’t matter, as invention had become more popular than inventor. Continue reading “BITCOIN, What is it actually???”

ISRO With A Perfect Solution To Fuel Crisis In India

isro Hybrid vehicle

After invading the skies, Indian Space Research Organization(ISRO) ,is now focusing on the automobile space with an emphasis on renewable energy. Since vehicles using fossil fuels persistently bring serious problems to environment and life. Electric vehicles are considered the future of transport. But the emissions are just transferred from the exhaust of the vehicle to the chimneys of the power plant. So Solar and Electrical energy based hybrid vehicles will provide the most effective and viable long-term solution by using renewable energy sources for mobility.

ISRO has been working on a number of sustainable initiatives in recent times. They recently launched a solar calculator app, that will help people install solar panels most optimally to derive energy. Now  the solar hybrid vehicle was successfully demonstrated in a test drive, including an uphill drive. Solar energy is available in abundance for free , and it is also a non-polluting source of energy. So, ISRO might solve a major problem in the electric vehicles.

New Solid-state Battery calls for Another Battery Revolution…

A noncombustible design and can recharge in a fraction of the time of a standard battery.

Have you ever wondered what 94 year old John Goodenough, co-inventor of the lithium-ion battery, is doing?? He is hoping to find another breakthrough in battery technology. I think, he has succeded. A team of scientists under him has developed the first all-solid-state battery cells that could lead to safer, faster-charging, longer-lasting rechargeable batteries for handheld mobile devices, electric cars and stationary energy storage.

Is Jack fruit a substitute staple food??

Jackfruit

Which fruit is the largest tree fruit in the world, do you think you could get the answer? Yes, if u said Jackfruit, then u r right. Our own jackfruit. Jackfruit is the largest known tree borne fruit. Even a small jackfruit weighs in at 10-15lbs (5-7kg), and farmers have recorded specimens of more than 100lbs (45kg). Jackfruit is believed to have originated in Southern India thousands of years ago,now cultivated worldwide in the tropical regions of the Indian subcontinent, Thailand, Malaysia, Indonesia and Brazil for its fruit, seeds, and wood. The tree grows best in tropical humid and rainy climates but rarely survives cold and frosty condition.

Magical Graphene Sieve for Sea water

Producing potable water through desalination may become more efficient and less energy-intensive if researchers at the University of Manchester are able to successfully use graphene oxide (GO) membranes to filter common salts in seawater on a commercial scale.

About 97 percent of the Earth’s water can be found in our oceans.With ever increasing needs of growing population, the problem of pure, clean drinking water is alsogrowing. Providing clean drinking water for millions of people who struggle to access adequate clean water sources is still a challenge. Scientists from the University of Manchester, led by Dr Rahul Nair, show how they solved some of the challenges by using a chemical derivative called graphene oxide. An effective and less energy-intensive desalination process using graphene has been developed which could give millions of people access to clean water.
