Till the stipulated time both the teams had a score of 1 goal each. Even India was leading with one goal till half time. Simaranjit Singh hit a goal for India. Jang Jong Hyun scored the goal for South Korea. Hosts Malaysia defeated Canada 4-2 and secured the 3rd place. Asian games Gold medalist Japan stood at 5th place, defeating Poland 6-1.

Notes:
The Hongkou district of Shanghai has recently claimed to have the world’s first district with 5G coverage and a broadband gigabit network. It conducted trial runs of the 5G network, backed by telecom services provider China Mobile. Shanghai also aims to build over 10,000 5G base stations by the end of this year and the number of 5G base stations could cross 30,000 in 2021. 5G is the next generation of cellular technology with download speed 10 to 100 times faster than the 4G LTE networks.

Notes:
Lewis Hamilton, a British racing driver, has won the 2019 Formula 1 Bahrain Grand Prix tournament after an engine problem hit runaway leader Charles Leclerc’s Ferrari late in the race.

Notes:
Researchers led by Kavli Institute for the Physics and Mathematics of the Universe in Japan has put a theory speculated by the late Stephen Hawking to its most rigorous test to date, and their results have ruled out the possibility that primordial black holes smaller than a tenth of a millimeter make up most of dark matter. They used the gravitational lensing effect to look for primordial black holes between Earth and the Andromeda galaxy. However, gravitational lensing effects are very rare events because it requires a star in the Andromeda galaxy, a primordial black hole acting as the gravitational lens, and an observer on Earth to be exactly in line with one another. In order to maximise the chances of capturing an event, the researchers used the Hyper Suprime-Cam digital camera on the Subaru telescope in Hawaii, which can capture the whole image of the Andromeda galaxy in one shot. Taking into account how fast primordial black holes are expected to move in interstellar space, the team took multiple images to be able to catch the flicker of a star as it brightens for a period of a few minutes to hours due to gravitational lensing. The team’s results showed primordial black holes can contribute no more than 0.1% of all dark matter mass. Therefore, it is unlikely the theory is true.

Notes:
South Korea will launch the world’s first fully-fledged 5G mobile networks on 5th April 2019. Hyper-wired South Korea has a reputation for technical prowess, and Seoul has made the 5G rollout a priority as it seeks to stimulate stuttering economic growth. The superfast communications heralded by fifth-generation wireless technology will bring smartphones near-instantaneous connectivity – 20 times faster than the existing 4G. It is crucial for the future development of devices ranging from self-driving vehicles that send data traffic to one another in real time, industrial robots, drones and other elements of the Internet of Things. 5G’s hyper speed can connect one million devices within a one square kilometre zone simultaneously. Until now, no mobile networks have offered nationwide 5G access. Japan is expected to roll out a limited deployment in 2019 before full services start in time for 2020 Tokyo Olympics.

Notes:
The United States has approved the sale of 24 multi-role MH-60 Romeo Seahawk helicopters to India under its Foreign Military Sales (FMS) program at an estimated cost of $2.4 billion. The multi-mission helicopters can detect, track and attack submarines and surface ships at sea. They are designed to operate from frigates, destroyers, cruisers and aircraft carriers. Thus, these are considered the world’s most advanced maritime helicopters. The choppers will provide the Indian defence forces with the capability to perform anti-surface and anti-submarine warfare missions along with the ability to perform secondary missions including vertical replenishment, search and rescue, and communications relay. Hence, the Lockheed Martin-built helicopters would replace India’s aging fleet of British-made Sea King helicopters. The proposed sale will support US foreign policy & national security by helping to strengthen the US-Indian strategic relationship and to improve the security of a major defensive partner.

Notes:
According to a new collaborative study by the Queen’s University Belfast and Aberystwyth University in the UK, the sun’s magnetic field is ten times stronger than previously thought. Using the Swedish one-metre Solar Telescope at Roque de los Muchachos Observatory, in the Canary Islands, David Kuridze studied a particularly strong solar flare which erupted near the surface of the Sun on September 10, 2017. A combination of favourable conditions and an element of luck enabled the team to determine the strength of the flare’s magnetic field with unprecedented accuracy. The researchers believe the findings have the potential to change our understanding of the processes that happen in the Sun’s immediate atmosphere. The study found that the sun’s corona extends millions of kilometres above the surface, measuring 1,400,000 kilometres across — 109 times larger than Earth — and 150,000,000 km from Earth. Solar flares appear as bright flashes and occur when magnetic energy that has built up in the solar atmosphere is suddenly released. These solar flares can lead to storms which, if they hit Earth, form the northern lights — the Aurora Borealis. They can also disrupt communications satellites and GPS systems.

Notes:
In Kerala, the group of science experts of the Hume Centre for Ecology and Wildlife Biology has decided to launch ‘Café Scientifique’ to promote science among public in an interesting way. It is the first such initiative in the state to popularise the subject. It envisages to bring science back into popular culture by demystifying scientific research for the public and empowering non-scientists to comfortably assess science and technology issues, particularly those that impact social policy making. The project is also aimed at making science relevant, powerful and important to the public, especially the younger generations. Here, various topics such as universe, climate change, evolution, genetics and human-animal relations will be discussed in every monthly gathering. It is a grassroots public science initiative based on the French Café Philosophique model.

Notes:
For the second successive year, Telangana has been ranked first in e-learning training programme of Department of Personal and Training (DoPT) of the Government India. In FY 2018-19, Dr. MCR HRD Institute had enrolled over 20,000 field staff in different districts of the State to impart training on 12 soft skill modules and three domain-specific modules on the RTI, office procedures, and finance and accounts, apart from Sustainable Development Goals (SDGs). The institute is also mentoring Punjab, Madhya Pradesh, J&K, Odisha, Uttarakhand, and Gujarat to guide trainers for e-learning training programme and develop modules in regional languages to spread the Comprehensive Online Modified Modules on Induction Training (COMMIT) programme as a national mission.
