Long range surface-to-air Barak-8 missile successfully test fired
India and Israel jointly developed most advanced long range surface-to-air missile (LR-SAM) Barak-8 was successfully test fired off the Odisha coast. The missile was test fired from a mobile launcher at the Integrated Test Range in Chandipur in Balasore district in Odisha. Barak-8 (Lightning 8 in Hebrew) is long-range nuclear capable ballistic missile, developed jointly by Israel and India. It has been designed and developed by DRDO, Israel Aero-space Industries and Israel’s Administration for the Development of Weapons and Technological Infrastructure. It is 4.5-meter long and weighs around 3 tonnes can carry a payload of 70 kilograms. It has a speed of Mach2.
Scientists successfully grow three-dimensional lungs in lab using stem cells
Scientists in the United States including those of Indian origin have successfully grown three-dimensional (3D) lungs in the lab, using stem cells. The 3D lungs or organoids was created by coating tiny gel beads with lung-derived stem cells and then allowing them to selfassemble into the shapes of the air sacs found in human lungs. To show that these tiny organoids mimicked the structure of actual human lungs, researchers compared it with real sections of human lung.
Indian Navy’s most Advanced Guided Missile Destroyer Mormugao launched
Indian Navy’s indigenously built most Advanced Guided Missile Stealth Destroyer ‘Mormugao’ was launched in Mumbai, Maharashtra. The bedecked ship was launched by Navy chief Admiral Sunil Lanba’s wife Reena at a function at Mazagaon Docks. It has been Christened ‘Mormugao’ after the Mormugao port of Goa, the home State of Union Defence Minister Manohar Parrikar. The stealth vessel was built by government-run Mazgaon Dock Shipbuilders Ltd and belongs to Visakhapatnam class of ships being constructed under Project 15B. Mormugao has a displacement of 7,300 tonne with maximum speed of over 30 knots. It is fitted also with the Barak-8 long-range missiles. The vessel has been fitted with multi-mission radar for surveillance along with medium range air and surface surveillance radar and other advanced electronic warfare and decoys.
Surgeons use robot to operate inside eye in world first
British surgeons have successfully performed the world’s first robotic operation inside the eye, potentially revolutionising the way such conditions are treated. The procedure was carried out at John Radcliffe hospital in Oxford, where surgeons welcomed its success. Current technology with laser scanners and microscopes allows surgeons to monitor retinal diseases at the microscopic level. This is the first time a device has been available that achieves the three-dimensional precision required to operate inside the human eye.
World’s first daily driverless bus service launched in Lyon, France
The world’s first daily driverless bus service has started in Lyon, France which will run in the city’s Confluence area. The driverless bus service includes two electric shuttles that will transport passengers on a ten-minute route hosting five stops. The driverless buses can hold up to 15 passengers and are electric buses. It has features like LIDAR radar technology and motion sensors will help to avoid accidents. The LIDAR radar technology allows these buses to know exactly where they are and to detect everything happening around them.
ISRO’s GSLV-F05 launches advanced weather satellite INSAT-3DR
The Indian Space Research Organization (ISRO) has successfully launched advanced weather satellite INSAT-3DR. The satellite was launched on board of Geo-synchronous Satellite Launch Vehicle (GSLV-F05), from the Satish Dhawan Space Centre in Sriharikota. So far this year, it was the seventh successful mission of ISRO including the IRNSS series and the scramjet propulsion mission. INSAT-3DR weighing 2,211-kg will supplement the services of INSAT-3D launched from French Guiana in July 2013. It has designed mission life of ten years.
China tests stealth-defeating quantum radar
China has claimed that it has successfully developed and tested a radar system that uses quantum entanglement to beat the stealth technology of modern military aircrafts. This first Chinese quantum radar was developed by the Intelligent Perception Technology Laboratory. Prior to it, US was only the country stealth-defeating quantum radar. Quantum radar is a device that uses quantum entanglement photons to provide better detec-tion capabilities than conventional radar systems.
NASA launches OSIRIS-REx spacecraft to collect samples from Bennu asteroid
The National Aeronautics and Space Administration (NASA), a US space agency has launched OSIRIS-REx spacecraft to collect samples from an asteroid 101955 Bennu and return to Earth. The spacecraft was launched onboard a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Air Force Station. OSIRIS-Rex stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer. It is an unmanned spacecraft and NASA’s first mission to collect samples from an asteroid and return to Earth. OSIRIS-Rex will travel for two years on a journey to Bennu, a near-Earth asteroid about the size of a small mountain.
India’s light utility helicopter maiden flight successful
Hindustan Aeronautics Limited (HAL) has successfully completed test flight of indigenous Light Utility Helicopter (LUH) Bengaluru. The LUH will replace the military’s obsolescent fleet of Chetak and Cheetah helicopters that have flown for over three decades.
GRSE hands over fast attack craft ‘Tihayu’ to Indian Navy
The Water Jet Fast Attack Craft (WJFAC), ‘Tihayu’ built by Garden Reach Shipbuilders and Engineers Limited (GRSE), Kolkata was handed over to the Indian Navy. The warship was handed over by Rear Admiral (Retd) A.K. Verma, Chairman and Managing Director, GRSE to the Commanding Officer of the ship Cdr. AjayKashov, at a ceremony held in GRSE. GRSE had earlier built and delivered ten (10) WJFACs to the Indian Navy during 2009 to 2011, which are proving well in service. The Indian Navy has placed order for four more of these WJFACs as ‘Follow-on’ ships.
MobiKwik launches one step offline payments with ‘Bubble Pin’
India’s largest digital payment company, MobiKwik has launched a one-step offline payments mode, called Bubble Pin.This pin is generated on the MobiKwik app when a user clicks on the ‘Pay at store’,and it is valid for 60 seconds.The pin is a combination of alphabets & numbers. To make a payment,the user needs to share this pin with the retailer. Bubble pin also makes the transaction more secure as no phone number is required to be shared.
NASA Scientist for first time sequences DNA in Space
The National Aeronautics and Space Administration (NASA) for the first time has successfully sequenced DNA in space aboard the International Space Station (ISS). The genome sequencing was undertaken for the first time in microgravity as part of the Biomolecule Sequencer experiment performed by NASA astronaut Kate Rubins. The experiments were undertaken by using commercially available DNA sequencing device called MinION on samples of mouse, virus and bacteria DNA.
ISRO tests Scramjet Rocket engine
The Indian Space Research Organisation (ISRO) has successfully test-fired its Scramjet Rocket Engine. which will use oxygen from the atmosphere thereby reducing launch cost, from the spaceport of Sriharikota.
For the first time scientists predict brain activity patterns
Researchers have, for the first time, decoded and predicted the brain activity patterns of word meanings within sentences, an advance that may help brain injury and stroke patients communicate better. The brain activity patterns were predicted using functional magnetic resonance imaging (fMRI) to measure human brain activation. With this, researcher can now predict 70% brain activity patterns. This study may help treat persons with brain injury and stroke patients to communicate better. It also makes key advances towards understanding how information is represented throughout the brain.
Scientists for first time develop laser from fluorescent jellyfish proteins
Scientists for the first time have developed LASER (light amplification by stimulated emission of radiation) from fluorescent jellyfish proteins that were grown in bacteria. The first of its kind represents a major advance break through in so-called polariton lasers operating at room temperature. To develop the fluorescent Polariton laser, scientists had engineered barrel-shaped fluorescent proteins from jellyfish DNA. They had filled optical microcavities (between two mirrors) with this protein before subjecting them to optical pumping. Nanosecond flashes of blue light from an external laser were used to bring the system up to the required energy to create laser light. After the threshold was reached for polariton lasing, scientists pumped more energy into the device setup that resulted in conventional lasing.
