  • Virtual human’ NEON

    NEONs are being called the world’s first artificial humans. They look and behave like real humans, and could develop memories and emotions — though from behind a 4K display.

    NEON

    • Star Labs is headed by India-born scientist Pranav Mistry who underlines that what was showcased at CES was the product of just four months’ work.
    • The company says NEONs are computationally created virtual humans — the word derives from NEO (new) + humaN.
    • For now, the virtual humans can show emotions when manually controlled by their creators.
    • But the idea is for NEONs to become intelligent enough to be fully autonomous, showing emotions, learning skills, creating memories, and being intelligent on their own.
    • Star Labs thinks they can be “friends, collaborators, and companions”, but all that is a few years away.

    How does it work?

    There are two core technologies behind his virtual humans.

    • First, there is the proprietary CORE R3 technology that drives the “reality, real time and responsiveness” behind NEONs.
    • It is the front-end reality engine that is able to give you that real expression.
    • The company claims CORE R3 “leapfrogs in the domains of Behavioral Neural Networks, Evolutionary Generative Intelligence and Computational Reality”, and is “extensively trained” on how humans look, behave and interact.
    • But in the end, it is like a rendition engine, converting the mathematical models to look like actual humans.
    • The next stage will be SPECTRA, which will complement CORE R3 with the “spectrum of intelligence, learning, emotions and memory”.
    • But SPECTRA is still in development, and is not expected before NEONWORLD 2020 later this year.

    How could NEONs be used?

    • NEONs are the interface for technologies and services.
    • They could answer queries at a bank, welcome you at a restaurant, or read out the breaking news on television at an unearthly hour.
    • This form of virtual assistance would be more effective, for example, while teaching languages, as NEONs will be capable of understanding and sympathizing.

    How are they different from Virtual Assistants?

    • Virtual Assistants now learn from all the data they are plugged into. NEONs will be limited to what they know and learn.
    • Their leaning could potentially be limited to the person they are catering to, and maybe her friends — but not the entire Internet.
    • They will not be an interface for you to request a song, rather they will be a friend to speak to and share experiences with.
    • Currently, its developer doesn’t want NEONs to have collective memory, or to share data among themselves.

  • Artemis Mission

    NASA wants to send the first woman and the next man to the Moon by the year 2024, which it plans on doing through the Artemis lunar exploration program. An Indian American astronaut named Raja Chari is set to accompany the crew in this mission.

    Artemis Mission

    • In 2011, NASA began the ARTEMIS (Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon’s Interaction with the Sun) mission using a pair of repurposed spacecraft and in 2012 the Gravity Recovery and Interior Laboratory (GRAIL) spacecraft studied the Moon’s gravity.
    • For the program, NASA’s new rocket called the Space Launch System (SLS) will send astronauts aboard the Orion spacecraft a quarter of a million miles away from Earth to the lunar orbit.
    • The astronauts going for the Artemis program will wear newly designed spacesuits, called Exploration Extravehicular Mobility Unit, or xEMU.
    • These spacesuits feature advanced mobility and communications and interchangeable parts that can be configured for spacewalks in microgravity or on a planetary surface.

  • Person in news: Swami Vivekananda

    January 12 is the birth anniversary of Swami Vivekananda, the famous spiritual leader and intellectual from the late 19th century. In his honour, the government of India in 1984 declared his birthday as National Youth Day.

    Swami Vivekananda early life

    • Vivekananda was born in Kolkata on January 12, 1863, as Narendra Nath Datta.
    • From an early age, he nurtured an interest in Western philosophy, history, and theology, and went on to meet the religious leader Ramakrishna Paramhansa, who later became his Guru.
    • He remained devoted to Ramakrishna until the latter’s death in 1886.
    • In 1893, he took the name ‘Vivekananda’ after Maharaja Ajit Singh of the Khetri State requested him to do so, changing from ‘Sachidananda’ that he used before.
    • After Ramakrishna’s death, Vivekananda toured across India, and set after educating the masses about ways to improve their economic condition as well as imparting spiritual knowledge.

    The Chicago address

    • Vivekananda is especially remembered around the world for his speech at the Parliament of the World’s Religions in Chicago in 1893.
    • The speech covered topics including universal acceptance, tolerance and religion, and got him a standing ovation.
    • He began delivering lectures at various places in the US and UK, and became popular as the ‘messenger of Indian wisdom to the Western world’.

    Return to India

    • After coming back to India, he formed the Ramakrishna Mission in 1897 “to set in motion a machinery which will bring noblest ideas to the doorstep of even the poorest and the meanest.”
    • In 1899, he established the Belur Math, which became his permanent abode.

    His legacy

    • Through his speeches and lectures, Vivekananda worked to disseminate his religious thought.
    • He preached ‘neo-Vedanta’, an interpretation of Hinduism through a Western lens, and believed in combining spirituality with material progress.
    • ‘Raja Yoga’, ‘Jnana Yoga’, ‘Karma Yoga’ are some of the books he wrote.
    • An important religious reformer in India, Swami Vivekananda is known to have introduced the Hindu philosophies of Yoga and Vedanta to the West.
    • Subhas Chandra Bose had called Vivekananda the “maker of modern India.”

  • Coronavirus

    A new virus has been identified by Chinese researchers which is responsible for a new pneumonia-like illness.

    Coronavirus

    • Coronaviruses are a specific family of viruses, with some of them causing less-severe damage, such as the common cold, and others causing respiratory and intestinal diseases.
    • A coronavirus has many “regularly arranged” protrusions on its surface, because of which the entire virus particle looks like an emperor’s crown, hence the name “coronavirus”.
    • Apart from human beings, coronaviruses can affect mammals including pigs, cattle, cats, dogs, martens, camels, hedgehogs and some birds.
    • So far, there are four known disease-causing coronaviruses, among which the best known are the SARS coronavirus and the Middle East Respiratory Syndrome (MERS) coronavirus, both of which can cause severe respiratory diseases.

  • [op-ed of the day] The age of ubiquitous drones and the challenges overhead

    Context

    Increasing the use of drones in warfare and other areas has brought into focus the potential the use of drones hold and the other issues related to its misuse.

    Recent events featuring drones

    • A drone was used by the U.S. to fire the missile at Qassem Soleimani to assassinate him.
    • A few days before that, less-lethal drones monitored crowds of student protesters rocking India.

    A potential area of use of drones

    • Military and Policing: Drones are largely used for military or policing purposes, but they also have other uses.
    • Recreation and Sports: They are used for recreation and sports. The Chinese company DJI dominates this space.
    • Logistics: Logistics is another use, with Amazon developing last-mile drone delivery.
    • At scale, this delivery model can save money, energy and time.
    • Domino’s extended this logic to deliver its first pizza by drone in New Zealand and is experimenting with scaling this model up in many markets.
    • Botswana has had some successful trials where drones have delivered blood and life-saving drugs to villages out in the wilderness.
    • Agriculture: A startup called Terraview uses drones with advanced image processing, machine learning, artificial intelligence, and augmented reality to increase the productivity of vineyards.
    • A drone can be used to measure the amount of grain that’s piled up after harvest.
    • Mining Output: Tata Steel has used drones quite effectively to measure mining output.
    • Access the inaccessible places: Drones can go where people cannot.
    • So, inspection and repair at remote wind farms on an island, or pipelines in the remote tundra, or equipment in a rainforest can be done more cheaply and precisely.
    • Drone surveillance is now widely used by the insurance industry in the aftermath of floods or pest inspections.
    • They can provide organizations a 360-degree view of the status of any construction project and its assets.
    • Explosive detection and defusing: In many places, it is just safer to send a drone, such as while using explosives in deep mines or defusing suspected bombs.
    • Wildlife protection and survey: drones are used to survey wildlife and detect poaching in the jungles of Africa.

    Drones as commodity

    • Drones will soon become a hardware commodity, much like personal computers.
    • It will be the software loaded on it that will be the real force-multiplier.
    • Industry 4.0 revolution: Business like “drones-as-a-service” will emerge, dramatically reducing the time taken for tasks and serving as a vital tool in the Industry 4.0 revolution.

    A potent tool for Swarm-attack by military

    • Perhaps the most fascinating developments will occur where drones originated, in
    • Drones will mutate into swarms, where multiple, intelligent, small drones act as one vast network, much like a swarm of birds or locusts.
    • Advanced militaries have drone swarms under trial that could revolutionize future conflicts.
    • These swarms could overwhelm enemy sensors with sheer numbers and precisely target enemy soldiers and assets using data fed into them.
    • They will be difficult to shoot down as there will be hundreds of small flying objects rather than one big ballistic missile.
    • The swarm will use real-time ground data to organize itself and operate in concert to achieve its goal.

    Issues with drones

    • It will be us humans who will decide whether we use drones for beneficial or malevolent ends.
    • National Security Issues: Drones have demonstrated the potentials for their threat to the security of a country. Drones are operated remotely and can strike where it want it to strike. Raising serious security issues.
    • Terrorism: Drones have been used by various terrorist organisations like ISIS in Syria and Iraq to hit their targets.
    • Aviation safety: Drones flying too close to commercial aircraft has called for regulations.
    • Privacy: Drones have been used by the paparazzi to take the images of individuals breaching their privacy.

    Conclusion

    Drones can indeed be a fantastic tool for good projects, from helping save the planet to identifying and nabbing criminals, and preventing the loss of human life. However, for that, we will have to change the DNA that they were born with, as lethal weapons of war. Otherwise, they will remain anonymous killers, wreaking death and destruction as they hover innocuously above.

     

  • Lithium-Sulfur Battery

    Researchers from Australia have claimed that they have developed the world’s most efficient lithium-sulfur (Li-S) battery, capable of powering a smartphone for five continuous days. With this equivalence, an electric car would be able to drive a distance of over 1,000 km in one charge.

    What are Lithium-Sulfur Batteries?

    • Researchers who have developed this new Li-S battery claim it has an “ultra-high capacity” and has better performance and less environmental impact.
    • This means that they may be able to outperform the Li-ion batteries by more than four times.
    • With Li-ion batteries, some disadvantages include their susceptibility to overheating and their being prone to damage at high voltages.
    • Such batteries also start losing their capacity over time — for instance, a laptop battery in use for a few years does not function as well as a new one.

    Construction

    While the materials used in the Li-S batteries are not different from those in Li-ion batteries, the researchers have reconfigured the design of the sulfur cathodes (a type of electrical conductor through which electrons move) to accommodate higher stress without a drop in overall capacity.

    Advantages of the Li-S batteries

    • Li-S batteries are generally considered to be the successors of the Lithium-ion (Li-ion) batteries because of their lower cost of production, energy efficiency and improved safety.
    • Their cost of production is lower because sulfur is abundantly available.
    • Even so, there have been some difficulties when it comes to commercialising these batteries, mainly due to their short life cycle and poor instantaneous power capabilities.

    Why is this development important?

    • As the market share of electric vehicles (EV) is increasing and people are becoming more aware and conscious of global warming and climate change.
    • There is a need for development in terms of the kind of batteries used in these vehicles.
    • The growth of the EV market is linked to the development of batteries that are cost-effective, more efficient and leave a smaller environmental burden.
    • Today, most EV use Li-ion batteries, but are slowly reaching their theoretical limits of being able to provide roughly up to 300-watt hour per kilogram of energy.
    • Thus arises the need for batteries that can store more energy to run these cars, and Li-S batteries are considered to be a good alternative.

  • Goldilocks Zone

    NASA has reported the discovery of an Earth-size planet, named TOI 700 d, orbiting its star in the “habitable zone”.

    Goldilocks Zone

    • A habitable zone, also called the “Goldilocks zone”, is the area around a star where it is not too hot and not too cold for liquid water to exist on the surface of surrounding planets.
    • Our Earth is in the Sun’s Goldilocks zone. If Earth were where the dwarf planet Pluto is, all its water would freeze; on the other hand, if Earth were where Mercury is, all its water would boil off.
    • Life on Earth started in water, and water is a necessary ingredient for life as we know it.
    • So, when scientists search for the possibility of alien life, any rocky exoplanet in the habitable zone of its star is an exciting find.

    TOI 700 d

    • The newest such planet was found by NASA’s Transiting Exoplanet Survey Satellite (TESS) mission, which it launched in 2018.
    • The star, TOI 700, is an “M dwarf” located just over 100 light-years away in the southern constellation Dorado, is roughly 40% of our Sun’s mass and size, and has about half its surface temperature.
    • The find was confirmed by the Spitzer Space Telescope, which sharpened the measurements that TESS had made, such as orbital period and size.
    • TOI 700 d measures 20% larger than Earth. It orbits its star once every 37 days and receives an amount of energy that is equivalent to 86% of the energy that the Sun provides to Earth.

  • Epiphany festival

    The Epiphany festival was celebrated in parts of India, such as Goa and Kerala. In Goa, the celebration is known by its Portuguese name ‘Festa dos Reis’, and in parts of Kerala by its Syriac name ‘Denha’.

    Epiphany or Three Kings’ Day

    • Epiphany is among the three oldest and major festival days in Christianity, the two others being Christmas and Easter.
    • It is celebrated on January 6 by a number of Christian sects, including Roman Catholics, and on January 19 by some Eastern Orthodox churches.
    • In the West, the duration between December 25 and January 6 is known as the Twelve Days of Christmas.
    • Epiphany is a feast day, or a day of commemoration, which in Christianity marks the visit of the Magi (meaning the Three Wise Men or Three Kings) to the Infant Jesus (Christ from his nativity until age 12).
    • According to Christian belief, the Magi — Balthasar, Melchior, and Gaspar (or Casper), the kings of Arabia, Persia, and India, respectively — followed a miraculous guiding star to Bethlehem to paid homage to the Infant Jesus.
    • The day also commemorates the baptism of Jesus in the Jordan River.

    Celebrations in India

    • In Goa, the Magi or Three Kings are called ‘Reis Magos’ in Portuguese.
    • The Reis Magos fort, and church, in Bardez, and the Three Kings Chapel in Cansaulim, get their name from the belief.
    • Communities in Bardez, Chandor, Cansaulim, Arossim, and Cuelim are known to celebrate Epiphany.
    • In Kerala, at the St. Mary’s Orthodox Syrian Cathedral in Piravom, ‘Denha’ is an important annual celebration, in which a big congregation takes part.

  • Indian Data Relay Satellite System (IDRSS)

    India plans to ring in its own era of space-to-space tracking and communication of its space assets this year by putting up a new satellite series called the Indian Data Relay Satellite System.

    Indian Data Relay Satellite System (IDRSS)

    • The IDRSS is planned to track and be constantly in touch with Indian satellites, in particular those in low-earth orbits which have limited coverage of earth.
    • In the coming years, it will be vital to ISRO whose roadmap is dotted with advanced LEO missions such as space docking, space station, as well as distant expeditions to moon, Mars and Venus.
    • It will also be useful in monitoring launches.
    • The first beneficiary would be the prospective crew members of the Gaganyaan mission of 2022 who can be fully and continuously in touch with mission control throughout their travel.
    • IDRSS satellites of the 2,000 kg class would be launched on the GSLV launcher to geostationary orbits around 36,000 km away.

  • Places in news: Nankana Sahib

    Recently tension mounted in Pakistan after few goons vandalized the Nankana Sahib Gurdwara.

    Nankana Sahib

    • Nankana Sahib is a city of 80,000 in Pakistan’s Punjab province, where Gurdwara Janam Asthan (also called Nankana Sahib Gurdwara) is located.
    • The shrine is built over the site where Guru Nanak, the founder of Sikhism, was believed to be born in 1469.
    • It was constructed by Maharaja Ranjit Singh, after he visited Nankana Sahib in 1818-19 while returning from the Battle of Multan.
    • It is 75 kms to the west of Lahore, and is the capital of Nankana Sahib district.
    • The city was previously known as Talwandi, and was founded by Rai Bhoi, a wealthy landlord.
    • Rai Bhoi’s grandson, Rai Bular Bhatti, renamed the town ‘Nankana Sahib’ in honour of the Guru. ‘Sahib’ is an Arabic-origin epithet of respect.

    Historical significance

    • During British rule, the Gurdwara Janam Asthan was the site of a violent episode when in 1921, over 130 Akali Sikhs were killed after they were attacked by the Mahant of the shrine.
    • The incident is regarded as one of the key milestones in the Gurdwara Reform Movement, which led to the passing of the Sikh Gurdwara Act in 1925 that ended the Mahant control of Gurdwaras.
    • In 2014, Pakistan had a memorial for the massacre built.
