DETAILS
Nov. 01, 2020: Researchers form ultra-strong coupling between photons and atoms. ITMO University researchers have demonstrated that individual atoms can be transformed into polaritons—quantum particles that are a mixture of matter and light, which are transmitted via optical fibers. In this new state of matter, photons and atoms form ultra-strong coupling for the first time. The results of this research can be used to control the properties of light and matter and to create quantum memory. Polaritons are interesting because photons make them perfect for storing units of information called qubits, while atoms ensure they can bond with other quasiparticles and give us more opportunities to control them. Thus, by acquiring long-living quasiparticles, we can increase the resilience of the quantum system as a whole.

Nov. 03, 2020: Scientists Develop a Drone That Can Enter Into Volcanoes and Predict Future Eruptions. With an estimated 300 active volcanoes on Earth, it is a challenge to monitor them all to send out early warnings before they erupt. Measuring volcanic gas emissions is also no easy task. However, a new report has shown how scientists have designed specially-adapted drones to help collect data from an active volcano in Papua New Guinea (PNG).
Nov. 03, 2020: State-run BSNL has written to the government that it should be fairly compensated for the losses that will accrue to it due to delays in rolling out 4G services. Although it's been a year since the government approved a Rs 70,000-crore revival package for the ailing BSNL and MTNL, the former is still struggling to put in place a tender to place orders for building its 4G network.
Nov. 04, 2020: Laser-based method to detect antibiotic resistant bacteria invented by UK scientists. By placing a reflective surface – a small stiff cantilever – in a filtered growth medium in a petri dish, and reflecting a laser off it onto a detector, the researchers said it is possible to detect bacteria as they pass through the path of the laser, therefore altering the signal at the detector.
Nov. 04, 2020:
Scientists discover a new magnetic quasiparticle. Neutron scattering reveals a new way for magnetic oscillations to stick together. sodium manganese oxide represents the first antiferromagnetic (moments aligned antiparallel) material that hosts a three-magnon bound state. This demonstrates that such quasiparticles are stable enough to form. Using multiple-magnon bound states as carriers of quantum information is important for future quantum technologies, and this work provides a model material for studying the formation and properties of these new quasiparticles.

Nov. 05, 2020: They tracked that fast radio burst to a weird type of star called a magnetar that's 32,000 light-years from Earth, according to four studies in Wednesday's journal Nature.It was not only the first fast radio burst traced to a source, but the first emanating from our galaxy. Astronomers say there could be other sources for these bursts, but they are now sure about one guilty party: magnetars.Magnetars are incredibly dense neutron stars, with 1.5 times the mass of our sun squeezed into a space.one outburst that happens every 16 days to a nearby galaxy and is getting close to pinpointing the source.Some of these young magnetars are only a few decades old.

Nov. 06, 2020: If the experimentally measured value differs significantly from the expected Standard Model value, it may indicate the existence of unknown particles whose presence disturbs the local magnetic field around the muon. "If there is actually a discrepancy between the predicted and measured values, it is further proof that the Standard Model, our current understanding of the contents of the universe, is incomplete,"

Nov. 08, 2020: Diwali teaches us that light triumphs over darkness, good over evil, knowledge over ignorance," said Johnson from 10 Downing Street in London on Friday. "Just as Lord Rama and his wife Sita found their way home after the defeat of the demon king Ravana, their way lit by many millions of lamps, so too we shall find our way through this, and we shall do so triumphantly," he said.
Nov. 08, 2020: Chandigarh: Indiatimes logoHumans Came From Sponges? Genes Linked To 700 Million-Year-Old Sea Sponges. Sea sponges, organisms with bodies full of pores that allow water to circulate through them, have dominated life on Earth since before dinosaurs. A new research now suggests that possibly the entire animal kingdom, including humans, shares important genetic mechanisms with sea sponges.
Nov. 08, 2020: A hospitality college in Bali, Indonesia, has begun accepting coconuts as a form of tuition payment from students facing economic hardship. Students can also pay using leaves from moringa and gotu kola plants, which can be converted into herbal soap and sold to raise money for the academy.
Nov. 09, 2020: Experiments at French particle accelerator probe the properties of supernovae. The action of neutrinos in supernovae is poorly understood. When the core of a massive star at the end of its life collapses on itself under the effect of gravity, the electrons in the atoms combine with the protons in their nuclei, producing protons along with neutrinos. The neutrinos produced in abundance then escape from the neutron star being formed at a speed even faster than light. So much so that 99% of the energy emitted by a supernova is in the form of neutrinos! when the core of the star collapses, the neutrinos may be captured by free neutrons or neutrons in aggregates (light nuclei)—a process likely to influence the evolution of the supernova.
Nov. 09, 2020: Brain can be made to teleport using lasers, finds study. The study, which was published in the journal Cell, explained that laser beams can be directed into the hippocampus, the area responsible for memory and learning to stimulate neurons called "place cells". The cells in the brain get active when an animal or a human being goes into a new environment, storing the location in the memory.
Nov. 09, 2020: Earthquake in Maharashtra: Magnitude 3.4 quake shakes Palghar, spreads panic. The earthquake on Monday was recorded at 5.31 am in Palghar. Last month also, a couple of tremors were experienced in Palghar. The district has been witnessing low to moderate intensity earthquakes since November 2018, especially in its Dahanu and Talasari talukas.
Nov. 10, 2020: Transmitting data from space to earth with laser filaments, light will carry far more information and move it faster than the radio waves we currently rely on.
Nov 11, 2020: Observation of four-charm-quark structure. However, no unambiguous signal of exotic hadrons was observed until 2003, when the X(3872) state was discovered by the Belle experiment. In the following years, a few more exotic states were discovered. The explanation of their properties requires the existence of four constituent quarks. Identification of pentaquark states is even more difficult, and the first candidates were observed by the LHCb experiment in 2015. All these known states contain at most two heavy quarks—the beauty or charm quark. A four-charm tetraquark is usually considered to be formed by a cc-diquark and abar{c}bar{c}-antidiquark attracting each other. The cc-diquark model successfully predicted the mass of the Ξcc++ baryon observed by LHCb in 2017.
Nov. 11, 2020: Kanpur boy develops air purifier robot. When operational, the robot can filter the polluted air and clean air would be released in the atmosphere whereas the polluted particles will remain behind in the air filter inside.

"Swami Vivekananda is one of the most beloved intellectuals and spiritual leaders India has been fortunate to produce. He enthused the youth with his message of freedom, development, harmony and peace in India. He inspired citizens to take pride in Indian civilisation, culture and its industrious spirit".
Nov. 12, 2020: One step closer: Muon-to-electron-conversion program reaches milestone in construction of novel experiment. When operational, the Mu2e experiment will reach 10,000 times the sensitivity of previous experiments looking for the direct conversion of a muon into an electron to test one of the fundamental symmetries in particle physics. The transport solenoid, a critical part of the experimental setup, is divided into two halves. Muons travel down the first half of the curvy corridor, where they are separated by charge. At the solenoid's midway point, they encounter a special device that permits only negatively charged muons to pass through to the second curved section. The negative muons then exit the transport solenoid and enter the next big magnet, the detector solenoid. There, they stop in a second target.
Nov. 13, 2020: The bright flash is the most intense infrared light from a short gamma-ray burst ever seen. It is more luminous than was theoretically thought possible, sending out more energy in half a second than the Sun will produce in its entire lifetime. The blast was spotted in May this year, when Nasa’s Hubble Space Telescope captured the glow, three days after the burst. Over the next few years, further material ejected from the blast should be visible telescopes, allowing astronomers to further explore what might have caused it.

And was centered about 21 miles (34 km) southeast of Mina, a town of about 155, at a depth of 3.73 miles (6 km), the USGS said.People reported feeling it across desert communities in western Nevada and in California's Sierra mountains.
Nov. 14, 2020: BSNL to start providing mobile services in Delhi, Mumbai from January next year.
Nov. 14, 2020: But there is another set of vibrations recorded during ocean storms that are inexplicable in the accepted theories for how stormy seas generate movements in the solid Earth. These vibrations, named Love waves after their 20th-century discoverer, jostle underground rock particles side to side—perpendicular to their path forward. Scientists have presented two plausible explanations. One idea is that when the vertical force pumping down from colliding ocean waves encounters a slope on the seafloor, it splits and forms the two different surface wave types: Rayleigh and Love.
Nov. 14, 2020: The festival of lights abroad. Many festivals are celebrated in different cities from Berlin to Bangkok in the year. Let's look at the festivals that are preferred for lamps and crackers. UK PM Johnson, Prince Charles extend Diwali greetings, talk of 'victory of light over darkness'. "Let's all take comfort from the meaning at the heart of this fantastic festival. And let the many millions of Diwali lights all over the world shine through the darkness as beacons of hope for a better future."
