'Tuberculosis-resistant' cattle developed in China.
Scientists from China’s Northwest A&F University have developed a genetically modified form of cows that are more resistant to bovine tuberculosis (TB).
The Navy intends to procure 57 naval fighter aircraft from a foreign supplier for its rapidly growing fleet of aircraft carriers. The government also wants to manufacture these planes in India under Indian Prime Minister's Modi’s Make in India initiative and tender has asked the original equipment manufacturers to respond to it.
Bovine TB is a risk to cattle in many countries, including parts of the UK, Africa and Asia. The research was published in the journal Genome Biology.

China tests missile with 10 nuclear warheads.
China has tested successfully a new version of a missile Dongfeng-5C missile which can carry up to 10 nuclear warheads  from the Taiyuan Space Launch Centre in Shanxi province, and flew to a desert in western China.
He flight test of the DF-5C missile was carried out in January 2017 using 10 multiple independently targetable reentry vehicles, or MIRVs. Earlier versions of the DF-5 either missile DF-5Ca have single warhead or from six to eight MIRVs.

Litchis Contains Toxins that May kill Children.
A team of Scientists from the United States and India in a study found that consuming litchi and then skipping the dinner can cause a very low blood glucose level, lower than 70 mg/dL, which may eventually lead to death especially in children.
The study was published in the Journal Lancet Global Health. The group of scientist made the study after over 100 children from the northern India’s Muzaffarpur, Bihar died mysteriously after eating litchi’s  and skipping the evening meal.

Quantum computing: Scientists set new data record.
Scientists from ORNL transferred 1.67 bits per qubit, or quantum bit, over a fibre optic cable, edging out the previous record of 1.63 per qubit.
US-based scientists have set a new record of data transfer via superdense coding, a process by which the properties of particles like photons, protons, and electrons are used to store information.
While computers transmit information in the form of bits (1 or 0), quantum bits can employ two states simultaneously and therefore represent more information than a traditional bit.

UIDAI Shuts Down 50 Fraud Sites Offering Aadhaar Services.
The Unique Identification Authority of India (UIDAI) has dismissed 12 websites and 12 mobile applications available on Google Play store that were offering Aadhaar-related services illegally.

NASA captures a star's death in 'rotten egg' nebula.
NASA's Hubble Space Telescope captured a rare photograph of a dying star, transforming from a red giant to a planetary nebula and ejecting outer layers of gas and dust at almost 10 lakh kmph.
The 'Rotten Egg' Nebula is called so because it contains sulphur, an element which smells like rotten eggs when combined with other elements.

Alibaba-made app helps find 611 missing Chinese children.
A mobile app developed by Alibaba helped Chinese authorities recover 611 missing children last year.
The 'Tuanyuan' app, which means 'reunion' in Chinese, sends push notifications with photos and descriptions to users who are close to the location of a child's disappearance.
The notifications are sent to users farther from the location of the disappearance till the child is found.

Juno Completes Its Fourth Flyby of Jupiter.
Juno spacecraft sent by US space agency NASA, orbiting the planet Jupiter has completed a close flyby of Jupiter for the fourth time.
Juno is currently in a 53-day orbit and its next close flyby of Jupiter will occur on March 27, 2017
The spacecraft was launched from Cape Canaveral Air Force Station on August 5, 2011 (UTC), as part of the New Frontiers program.

Underwater harbour defence, surveillance system launched.
The IUHDSS is a state of the art system with integrated radars, electro optic cameras and sonars.
Vice Admiral Girish Luthra, Flag Officer Commanding- in-Chief, Western Naval Command inaugurated the Integrated Underwater Harbour Defence and Surveillance System (IUHDSS)
The system has been developed to strengthen Harbour Defence and Security at Mumbai. It will enhance the security of the valuable assets against surface and underwater threat.
UUHDSS has been designed and developed by Israeli Aerospace Industries (IAI) ELTA. It consists of integrated radars, electro-optic cameras and sonars.

Patent reveals Intel working on a curved 2-in-1 laptop.
American technology major Intel has patented a 2-in-1 laptop with a curved display. The patent describes the device as an "electronic device with detachable curved display" and also features a keyboard which is as thick as the display.
The hybrid laptop has a similar configuration to Microsoft's Surface Pro devices.

Scientists unveil world’s smallest pacemaker, no bigger than a vitamin pill.
Oncologists in United States successfully implanted World's smallest pacemaker,Micra Transcatheter Pacing System (TPS), in a patient in US.
The pacemaker TPS is as much as a vitamin capsule in size and provides the most advanced pacing technology.
The TPS system was approved by the US Food and Drug Administration (FDA)

US and Japan Successfully Conducts Test Flight of New Ballistic Missile Defence System.
The United States and Japan successfully conducted a flight test of a Standard Missile-3 (SM-3) Block IIA from the Pacific Missile Range Facility at Kauai, off coast Hawaii
The next-generation SM-3 Block IIA Interceptor has been jointly developed by the U.S. defense firm Raytheon and Japan's Mitsubishi Heavy Industries to destroy an incoming ballistic missile target and is launched from US warship.
The two nations have been working together since 2006 and America has so far spent about $2.2 billion on the system and Japan about $1 billion.
The US warship USS John Paul Jones, a Arleigh Burke-class guided missile destroyer detected and tracked the target missile with its onboard radar using the Aegis Baseline 9.C2 weapon system.

Stomach acid powers up MIT's ingestible battery.
MIT (Massachusetts Institute of Technology) researchers have designed and demonstrated a small ingestible battery that is powered by the acidic fluids in the stomach.
The 4-cm-long cylindrical cell can generate enough energy to power drug delivery devices and ingestible sensors for temperature, heart and breathing rate. During tests, the device was able to power a temperature sensor and transmit data wirelessly every 12 seconds.

ISRO, lifeguard agency collaborate to study killer tides.
A team of scientist at Indian Space Research Organisation (ISRO) along with a private lifeguard agency appointed by the Goa government is conducting a new study to understand the phenomenon of ‘killer rip tides’ to safeguard beaches in Goa.
ISRO Scientists have collaborated with Drishti Lifesaving, a private agency appointed by the state tourism ministry to conduct a study titled Ripex 2017 at Space Applications Centre, ISRO Ahmedabad.
A Rip Tide is a strong sea current which pulls the water away from the shore often catching unawares swimmers and people too along with it

India likely to test fire homegrown AAD interceptor missile.
India successfully test-fired its Advanced Air Defence (AAD) interceptor missile from launching complex-IV of Dhamara Abdul Kalam defence base off Odisha coast under its Ballistic Missile Defence Programme 
The successful testing leads India towards achieving a robust two layered Ballistic Missile Defence (BMD) system. It will strengthen India’s position in the exclusive club of US, Russia and Israel.
The Advanced Air Defence interceptor named as Ashwin has the capability to destroy the incoming enemy missile in the endo-atmospheric region at a low altitude of less than 30 kilometres.
