Dec. 16, 2020: What is particularly exciting for the scientists at JAXA is that the sample collection attempts managed to snag not only dusty material but also larger chunks. These pebbles and small rock debris could provide even more information about the formation and life of the asteroid, as well as other rocky bodies in our solar system. The agency owes this to the fact that the spacecraft performed two sample collection maneuvers and it appears as though the compartment used during the first touchdown has even more material than the scientists thought. This is the first time a gas sample has been collected from deep space.
Dec. 16, 2020: Lakes in India:The largest freshwater lake located in the North-Eastern part of India is the Loktak Lake. It is known for the Phumdis, which is a series of islands exclusive to this lake in Moirang, Manipur. Further, the area of this beautiful lake is 287 km and length 35 km. / The Changu lake is situated at a distance of 40 kilometers from Gangtok, the capital city of the state. And is elevated to a height of 3,753 m (12,313ft). / This is another glacial lake that is located at an altitude of 4,135 meters, about 14200 feet above sea level. Vasuki Tal or lake is situated in the holy state of Uttrakhand and is considered to be scared, not only that, this lake offers a magnificently enthralling view of the neighbouring Chaukhamba peaks and is a paradise for trekkers. / Gavi is a charming hamlet located in the Pathanamthitta district of Kerala. And in this small village is a beautiful lake that also goes by the same name. / Kareri Lake is located in the southern region of the Dhauladhar range, North West of Dharamshala in the Kangra district of the beautiful state of Himachal Pradesh. It is a shallow, freshwater lake that is situated 2934 meters above sea level. There is a temple(temples that worship a menstruating goddess) dedicated to Lord Shiva and Shakti on a hilltop.
Dec. 16, 2020: It turns out, our solar system also has a network of routes that would allow spacecraft and probes to travel much faster than they otherwise would. These are linked to the gravitational forces at work and are known as œcelestial autobahn or œcelestial highway. Researchers say that these routes could be used by spacecraft to travel the far reaches of the planetary system faster than otherwise which means they’ll take less time, and also to monitor and understand how near-Earth objects may collide with the planet. This study comes as part of a paper published in an issue of Sciences Advances.

Dec. 16, 2020:
Physicists Create Time-Reversed Optical Waves For The First Time. Interference can make a once simple wave complex as it spreads. Time reversal involves collecting all that complexity and inverting it to recreate the wave's original form. It's already common with water and sound waves, and even in relatively low-frequency electromagnetic waves. Mounaiz and Carpenter announce they have succeeded, passing pulses of wavelengths around 1,551.4 nanometers in the infrared, through optical fibers that split the pulses along many optical paths to create a complex output that was collected and time reversed.
Dec. 16, 2020: 5.0-magnitude quake strikes Japan''s Hokkaido Prefecture region the temblor`s epicenter was located at a latitude of 42.7 degrees north and longitude of 144.2 degrees east and occurred at a depth of 60 km.
Dec. 17, 2020 Two hours ago: Antarctica Has Been Rocked by 30,000 Tremors in Past Three Months, Chilean Scientists Say. "Most of the seismicity is concentrated at the beginning of the sequence, mainly during the month of September, with more than a thousand earthquakes a day," the center said. The shakes have become so frequent that the strait itself, once increasing in width at a rate of about 7 or 8 mm (0.30 inch) a year is now expanding 15 cm (6 inches) a year, the center said. "It's a 20-fold increase ... which suggests that right this minute ... the Shetland Islands are separating more quickly from the Antarctic peninsula,

Dec. 17, 2020, 6:39 pm: PSLV-C50 launches communication satellite CMS-01 into orbit. India's workhorse Polar Satellite Launch Vehicle (PSLV-C50) successfully launched the country's 42nd communication satellite, CMS-01, into its intended orbit this afternoon. PSLV-C50 lifted off from the Second Launch Pad (SLP) at the Satish Dhawan Space Centre (SDSC) at Sriharikota in Andhra Pradesh, on the eastern coast of the country, at 1541 hours today with CMS-01 as its sole passenger. After a flight of about 20 minutes 12 seconds, the vehicle injected the satellite into its intended orbit as planned, Indian Space Research Organisation (ISRO) said. After injection, the solar panels of CMS-01 were automatically deployed and ISRO’s Master Control Facility at Hassan assumed the control of the satellite. In the coming days, orbit raising manoeuvers will be executed to position the satellite in the Geostationary Orbit at its designated location, an ISRO press release said.

Dec. 18, 2020: The incredible, variable bacteria living in your mouth. Researchers take a closer look at the genomes of microbial communities in the human mouth. Researchers have examined the human oral microbiome and discovered tremendous variability in bacterial subpopulations living in certain areas of the mouth. In many cases, the team was able to identify a handful of genes that might explain a particular bacterial group's habitat specificity. For instance, the microbes found on the tongue are very different from the microbes found on the plaque on teeth. "Your tongue microbes are more similar to those living on someone else's tongue than they are to those living in your throat or on your gums!" said Eren.
Dec. 18, 2020: Earthquake hits Delhi-NCR, epicentre near Rajasthan's Alwar. the earthquake struck the area at 11.46 pm. The tremors prompted people to rush out of their houses even as the mercury dipped because of the cold wave. The tremors were felt in parts of Delhi, Noida and Gurugram. Earlier in the day, an earthquake of 3.0 magnitude on the Richter scale occurred in Jaipur on Thursday. The tremors were felt around 11 am, 64 km north west of Jaipur. "Earthquake of Magnitude:3.0, Occurred on 17-12-2020, 11:26:01 IST, Lat: 27.40 and Long: 75.43, Depth: 5 Km, Location: 64km NW of Jaipur, Rajasthan, India,"
Dec. 18, 2020:
New topological properties found in "old" material of Cobalt disulfide. Schoop Lab discovered the presence of Weyl nodes in bulk CoS2 that allow them to make predictions about its surface properties. The material hosts Weyl-fermions and Fermi-arc surface states within its band structure, which may enable it to serve as a platform for exotic phenomena and places it among materials candidates for use in spintronic devices. The research also settles a long-standing debate, proving that CoS2 is not a true half-metal. A half-metal is any substance that acts as a conductor to electrons of one spin orientation but as an insulator or semiconductor to those of the opposite orientation.Researchers found that bulk CoS2 contains objects called Weyl nodes within its structure that serve as electronic channels that can predict other states at the surface."These electronic states that only exist at the surface have chirality associated with them, and because of that chirality the electrons can also only move in certain directions. Chirality refers to that property that makes an object or system indistinguishable from its mirror image—i.e. not superimposable—and is an important property in many branches of science. Schoop added that the electronic channels are polarized. This magnetism could potentially be used to manipulate the material: scientists can switch the magnetization direction and surface states could then be reconfigured as a response to this applied magnetic field.

Dec. 19, 2020: Digging work for the expansion of the renowned Mahakaleshwar Temple in Ujjain in Madhya Pradesh was stopped after the remains of a structure that may be a 1000 years old were found. Solanki said the structure could be 1000 years old belonging to the time of the Parmar dynasty, as the red brown basalt found during the excavation was used during that period. "Further excavation around the temple may bring up relics from the period of Vikramaditya some 2600 years ago."
Dec. 19, 2020: In a study now published in the journal Astronomy & Astrophysics, the researchers found that the Tau Bootes exoplanet system exhibited a significant radio signature.

Dec. 20, 2020 6:46 pm IST: According to the space.com, it is being suggested that the "two planets might be a replica of the legendary Star of Bethlehem". Many astronomers and scientists have tried to find out whether the 'Star of Bethlehem' really ever existed. One of the theories claim that in the year 7 B.C., Jupiter and Saturn had three conjunctions in the same constellation and that could possibly explain it."It's been nearly 400 years since the planets passed this close to each other in the sky, and nearly 800 years since the alignment of Saturn and Jupiter occurred at night, as it will for 2020, allowing nearly everyone around the world to witness this 'Great conjunction'". Ursid meteor shower around the Jupiter-Saturn conjunction. The Ursid meteor shower has been active since December 17 and will peak on December 21-22.

A Reuters photographer captured a stunning photo of lightning striking Japan's Mount Sakurajima volcano on Thursday. Located in southern Kyushu, Sakurajima is one of the world's most active volcanoes, spewing ash and lava every four to 24 hours. The photo shows bolts of lightning colliding with the mouth of the volcano. The Sakurajima volcano range is one of the world’s most active volcano sites. Especially combined with the lightning storm, the eruptions are considered to be one of the most powerful clashes in nature. When lightning appears to be striking down onto the volcano or even on its mouth, it is known as volcanic lightning. Though many have studied this phenomenon for years, there is a lot still to be explored about what causes this spectacular phenomenon or why. The reason for a lack of study is quite obvious; it’s really dangerous to be around a live, active volcano especially during an eruption.

Amazonian Tree with human sized leaves is finally classified as a new species. Scientists have known about this extremely rare tree for decades, but did not have any genetic material to describe it. In 2005 a couple of botanists collected seeds from a tree in Jamari National Forest, a ancient tropical forest in the Amazon. They took the seeds and planted them and waited for one to flower. Thirteen years later one of the trees flowered and bore fruit, giving the genetic material necessary to name the new species. Coccoloba gigantifolia.

Dec. 22, 2020 an hour ago: Two strange blobs of X-ray energy are swirling out of the galaxy's center. These newly-discovered orbs are more than 45,000 light-years wide — but what created them? Today, those blobs — now named the Fermi Bubbles — span half the width of our galaxy. One lobe towers for 25,000 light-years above the Milky Way's disk, and the other looms just as large below it. Since their discovery in 2010, the bubbles have been a monolithic mystery of our galaxy — and now we know they are not alone. As scientists continue to study our galaxy in every wavelength of light imaginable, strange new structures within the Fermi Bubbles — from "chimneys" of plasma to slowly inflating balloons of radio energy — continue to emerge.

Spitzer also detected infrared radiation from sources so far away that in effect it looked almost 13 billion years back in time to when the universe was less than 1 billion years old. Spitzer showed that even in that early epoch some galaxies had already grown to the size of present-day galaxies and that they must have formed within a few hundred million years of the big bang that gave birth to the universe some 13.7 billion years ago. Because Spitzer was sensitive to infrared radiation emitted from dust, it also discovered Saturn’s outermost ring, which extends from 7.3 to 11.8 million km (4.6 to 7.4 million miles) from Saturn and is the largest planetary ring in the solar system. This dust ring arises from impacts on the moon Phoebe, and particles from this ring that spiral inward toward Saturn have caused the marked asymmetry in brightness between the two hemispheres of Iapetus.

Dec. 23, 2020: Source: Goethe University Frankfurt: Summary: For the first time, an international team of scientists has succeeded in filming quantum physical effects on a helium dimer as it breaks apart. The film shows the superposition of matter waves from two simultaneous events that occur with different probability: The survival and the disintegration of the helium dimer. This method might in future make it possible to track experimentally the formation and decay of quantum Efimov systems. However, if the gas is cooled down to just 10 degrees above absolute zero (minus 273 °C) and then pumped through a small nozzle into a vacuum chamber, which makes it even colder, then -- very rarely -- such helium dimers form. These are unrivaledly the weakest bound stable molecules in the Universe, and the two atoms in the molecule are correspondingly extremely far apart from each other. While a chemical compound of two atoms commonly measures about 1 angstrom (0.1 nanometres), helium dimers on average measure 50 times as much, i.e. 52 angstrom.That the researchers were able to observe and film the helium atom flying away as a wave at all in their laser experiment was due to the fact that the helium atom only flew away with a certain probability: With 98 per cent probability it was still bound to its second helium partner, with 2 per cent probability it flew away.These two helium atom waves -- Here it comes! Quantum physics! -- superimpose and their interference could be measured.

Dec. 25, 2020:This New Type of Glue Is Activated by Magnetic Fields, And Really Easy to Use. A newly developed glue that gets its stickiness from a magnetic field could lead to serious energy and cost savings for companies that need to stick things together on an industrial scale. To harden – or cure – the mix of chemicals in most epoxy-based glues, some kind of environmental effect like heat, light, or moisture needs to be applied. Here, that's being achieved by a "magnetocuring" process, which is being promoted as an option for when conventional adhesives aren't particularly effective, or in heat-sensitive applications, or for when a lot of insulating material is involved (making it tricky to apply heat, light, or moisture). The glue works by combining a commercial epoxy with custom-made magnetic nanoparticles that mix manganese, zinc, and iron: these nanoparticles heat up when electromagnetic energy is passed through them, fastening the materials in place. "Our key development is a way to cure adhesives within minutes of exposure to a magnetic field, while preventing overheating of the surfaces to which they are applied," says materials scientist Terry Steele from Nanyang Technological University (NTU) in Singapore.

Dec. 26, 2020: The origin of the Mysore Sandal Soap can be traced to World War 1. In 1916, the war blocked the export of sandalwood from Mysore to major Western countries. The Maharaja of Mysore, Nalwadi Krishnaraja Wodeyar, chanced upon unused sandalwood reserves and ordered the extraction of oil from the aromatic wood. Two years later, after the king received a rare set of sandalwood soap from a foreigner, he asked Dewan Sir M. Visvesvaraya, to map out a plan of action to begin the production of such soaps in Mysore. They sent Sosale Garalapuri Sastry, now popular as ‘Soap Sastry’, one of India’s first industrial chemists at the Indian Institute of Science, Bengaluru, to England to master the art of soap making.
Dec. 27, 2020: Varanasi farmers learn to use drones for seed plantation, the drones were used in the fields of the `rice-wheat cropping system`, where tractors could not be used for tilling due to wet soil. This cropping system is the main feature of the Indo-Gangetic plains. He said both rice and wheat have different soil requirements. If rice needs stagnant water conditions, wheat requires well-pulverised soil balanced with moisture, air and thermal regime. Due to this a key feature of the `rice-wheat cropping system` is the annual conversion of soil from aerobic to anaerobic and then back to aerobic conditions.

Dec. 28, 2020: The mystery behind a diamond-studded meteorite that exploded over Sudan in 2008 has been somewhat revealed as per researchers at Southwest Research Institute based in Texas, US. The study suggests that the meteorite was part of a giant asteroid in our solar system, which was the same size as the dwarf planet Ceres. The latter is the largest celestial object in the asteroid belt.the meteorite before impact, as per the calculations, it was 13 foot in diameter and weighed 8,200 kg. A sample of 50 grams analysed by a team under an infrared microscope has found that the meteorite had a unique mineral makeup, including 'amphibole' which requires prolonged exposure to water in order to develop.
Dec. 28, 2020: Ripples in space-time could provide clues to missing components of the universe. For example, one theory for the missing piece of the universe is the existence of an extra particle. Such a particle would, among other effects, generate a kind of background or "medium" around large objects.

December 29, 2020: New Views of Quantum Jumps Challenge Core Tenets of Physics. One of the most basic processes in all of nature—a subatomic particle’s transition between discrete energy states—is surprisingly complex and sometimes predictable, recent work shows. Everyday experience, of course, tells us this is not the case, but for the less accessible microscopic realm, the true nature of such “quantum jumps” has been a major unsolved problem in physics. In recent decades, however, technological advancements have allowed physicists to probe the issue more closely in carefully arranged laboratory settings. The most fundamental breakthrough arguably came in 1986, when researchers for the first time experimentally verified that quantum jumps are actual physical events that can be observed and studied. Ever since, steady technical progress has opened deeper vistas upon the mysterious phenomenon.The system transitions by passing through a mixture of the excited state and ground state, a quantum phenomenon known as superposition. But sometimes, when the connection exceeds a certain threshold, this superposition will shift toward a specific value of the mixture and tend to stay at that state until it moves to the ground unannounced. In that special case, “this probabilistic quantum jump cannot be predicted and reversed midflight,” explains Parveen Kumar.
Dec. 29, 2020: When the universe was a fledgling billion years old, a galaxy spewed a ginormous, fast-moving jet of radiation and plasma into the cosmos. Nearly 13 billion years later, that jet is visible to humans in the form of a blazar. The jet was recently imaged and analyzed by a team of Italian astronomers. a bright-orange jet of plasma, pointed roughly at us and stretching about 1,600 light-years long, a distance that defies any terrestrial analogy.
Dec.29, 2020: SISAK, Croatia (Reuters) -Second earthquake in two days strikes central Croatia, killing seven and damaging buildings. An earthquake of magnitude 6.4 struck central Croatia on Tuesday, killing seven people, injuring more than 20 and rattling several neighbouring countries, officials and residents said. It hit at 1119 GMT at a depth of 10 km (6 miles), with the epicentre in Petrinja, 50 km south of Zagreb. It hurt as far away as Austria’s capital Vienna. Slovenia shut its only nuclear power plant as a precaution.

9.4.2020 12:56 AM: PHYSICISTS DISCOVER "ANTI-GRAVITY" IN BIZARRE BUOYANCY EXPERIMENT. But, while this discovery may be ancient, a team of French physicists has now discovered a new kind of buoyancy that they call "anti-gravity." In both theoretical and experimental trials, the researchers found that objects, such as small toy boats, could float on the opposite side of levitated fluids instead of falling down due to gravity. IS PHYSICS BROKEN? — The researchers were able to validate their results with theoretical calculations as well, meaning that this event was not simply a fluke but instead a fundamental characteristic of how vibrations affect dense liquids. The researchers are excited about what other bizarre states like this might exist in the fields of chemistry or biology, they say in the paper. Discovering what anti-gravity could mean in these fields offers great potential for future research, write the authors.
