DETAILS

16 February 2018, 9:31 pm EST: But Aditya Venkatramani at Harvard University, Sergio Cantu at the Massachusetts Institute of Technology, and their colleagues found a way to make photons stick together. Scientists Created New Form of Light With Potential Use In Quantum Computing:  Groups of three photons interacting and essentially sticking together to form a new kind of photonic matter. The discovery of this new form of light may be used to perform complex and fast quantum computations. Different From Normal Light. The photons in the lightsaber beams would collide and crash into each other.  Photons from two beams of normal light from flash lights, on the other hand, would pass right through each other. In experiments, observed that when a very weak laser beam passes through a thick cloud of cold rubidium atoms, the photons come out bound together in pairs or in groups of three instead of exiting as single randomly spaced  photons. The photons are like some form of atom-size lightsaber. The results suggest some kind of interaction taking place among the light particles. The observation of traveling three-photon bound states in a quantum nonlinear medium where the interactions between photons are mediated by aic Rydbtomerg states. Photon correlation and conditional phase measurements reveal the distinct bunching and phase features associated with three-photon and two-photon bound states. More Sluggish Than Normal Light Particles: Normal photons also do not have mass and travel at a speed of 300,000 km per second, but the researchers found that the bound photons acquired some mass, equivalent to a fraction of that of an electron's. They are also relatively sluggish and travel 100,000 times slower than the speed of light. Potential Applications In Quantum Computing: As photons have been shown to indeed attract or entangle each other, the researchers said that they can be harnessed to perform quantum computations.  If photons can influence one another, then if you can entangle these photons,  you can use them to distribute quantum information in an interesting and useful way.

16 Feb. 2018: Strong rip currents make Visakhapatnam beaches unsafe. Studies made by Oceanography experts suggest that a few locations in the coastal sretch of Port City are not safe  for swimming. Rip Current forecost exists along the 60 km stretch  along the Visakhapatnam beach. Strong wavesat Arilova, Rushikonda and Judugulapalem are very dangerous.  

16 Feb. 2018: A winter storm will move through the Lehigh Valley this weekend and could bring significant snowfall to parts of the area, less than 48 hours after some areas saw near-record warmth. A winter storm watch in effect from Saturday evening through early Sunday morning for wet, heavy snow. The warning came a day after highs pushed into the upper 60s in Allentown. The track of the storm this weekend would bring the heaviest snow amounts to the Lehigh Valley and the Poconos, with amounts decreasing as you move south. This would mean 4 to 6 inches of snow in Carbon, Monroe, Berks, Lehigh and Northampton counties, but lower amounts closer to the Interstate 95 corridor. The high end totals of the storm could bring as much as eight inches of snow to Mount Pocono. Immediately east, New Jersey could see more snow than the Lehigh Valley.   
Feb 13, 2018, 11:13 AM: PORT BLAIR: An earthquake of 5.6 magnitude hit the Andaman Islands on Tuesday morning. As per the meteorological department, the earthquake occurred at around 8: 09 AM in the  morning.

Saturday 17 February 2018:22:24, UK hit by biggest earthquake for a decade. A 4.4 magnitude tremor hits South Wales, but its effects are felt as far away as Liverpool, Birmingham and Cornwall, with a depth of 7.4km, and the epicentre was about 20km north of Swansea. The quake happened just after 2.30pm on Saturday.

Feb 17 2018 12:24AM: A Russian skier was killed while his compatriots were rescued after an avalanche hit the ski-resort Gulmarg on Friday. A group of Russian skiers comprising 9 members left this morning for skiing in Gulmarg. However, despite being warned not to venture into the prohibited area, the skiers went in the “danger zone”, where they were hit by an avalanche.

                                   Fig.1 Earthquake of magnitude 7.2R  shook Mexico City

Powerful earthquake with 7.2 magnitude shakes Mexico City: A powerful earthquake shook Mexico City on Friday, triggering the capital`s quake alarm system and causing buildings to sway. the magnitude of the quake at 7.0, and seismic monitor network Sky Alert said the quake was felt across the states of Guerrero, Oaxaca and Puebla. The USGS initially gave the quake`s magnitude as 7.5, later revising it down to 7.2, and located its epicenter 37 km (22 miles) northeast of Pinotepa de Don Luis, in the southwestern state of Oaxaca.
17 February, 2018: Delhi, Haryana told to resolve polluted water supply issue. The DJB had claimed that while at the source point in Haryana, the ammonia content in the water was negligible, the source point in Delhi saw high levels of ammonia. The colour of the water being received from Haryana is blackish in colour and has a foul smell.

Drought California: About 45 percent of California was experiencing some level of drought conditions as of Feb. 6, 2018.
17 Feb 2018: URANUS AND NEPTUNE: New Form of Water, Both Liquid and Solid, Is ‘Really Strange’. Long theorized to be found in the mantles of Uranus and Neptune, the confirmation of the existence of superionic ice could lead to the development of new materials.This new form, called superionic water, consists of a rigid lattice of oxygen atoms through which positively charged hydrogen nuclei move. It is not known to exist naturally anywhere on Earth, but it may be bountiful farther out in the solar system, including in the mantles of Uranus and Neptune.
17 Feb 2018: Atom is Visible:

                                               Screaming Mummy left gry in sheep skin.

An ancient papyrus record from Egypt refers to a prince sentenced to be hanged to death for conspiring against his father. The marks around the neck of the screaming mummy appear to confirm this account. The 'Screaming Mummy' instead, was left out to dry and wrapped in sheepskin which was considered impure by ancient Egyptians.

18 Feb. 2018: ISTANBUL –  Turkey's military says two soldiers are missing in a flood after heavy rains pummeled the country's southeast, and Turkish media reported that their armored vehicle had toppled into a river. In a statement Sunday, the army said the soldiers were on guard in southeastern Sanliurfa province on the border with Syria before being swept away in the flood early Sunday.

20 Feb. 2018: Vodafone has created the world’s first Radio Positioning System (RPS) for drones which uses a 4G SIM to communicate with other drones. These IoT drones are easy to track and safer than the commercial civilian drones. The tech behind RPS will be utilized for other IoT services like tracking luggage using tags. RPS might also end up replacing GPS for better location tracking to enhance security. What is RPS and what are its capabilities? The Radio Positioning System RPS is capable of tracking each drone in real-time with 50 meters accuracy for drone operators and air traffic control. It gives over the horizon, beyond the line of sight control to the operator which reduce the risk of accidents after operator losing the line of sight.

World's Smallest  Rocket Japan credit: The SS-520 rocket, about the size of a lamp post and 50 centimeters in diameter, lifted off from the Uchinoura Space Center in Kagoshima and placed its payload in the intended orbit, according to Japan’s space agency JAXA.

The recent archaeological excavations Odisha’s Bargarh district has unearthed stone tools, weapons and artefacts made by early humans, centuries ago. The excavation site located in the upper Danta stream, a tributary of the River Jira, near Torajunga village of the district, is a storehouse of treasure. This discovery will help us in understanding migration and subsequent colonisation by human beings in this part of India. The tools bear striking similarities with those found in Eastern and Southern Africa. Most of them were designed for hunting large animals.

Social-media users has been buzzing with compliments for the personnel from praising their amazing fitness level to saluting their sacrifice and dedication for the nation. Photographed against the picturesque Himalayan ranges, the breath-taking photos are a fine example of their strength and fitness levels. These photos of the personnel, who are also popularly known as Himveers, are breaking the internet.
24 Feb. 2018: Massive Black Holes: Scientists have detected a set of gargantuan black holes that are likely the most massive ever discovered in the universe. The “ultra-massive” black holes are located up to 3.5 billion light years from Earth. They were spotted using data captured by NASA’s Chandra X-ray telescope, a space observatory that has greatly advanced the field of X-ray astronomy.
25 Feb. 2018: NATURAL COLOURS IN PHAGUN: It falls in the month of phagun and this year it is on March 2. It is celebrated by applying colours on each other and enjoying food and drinks. Earlier the colors used for Holi made using flowers.You can make both dry and wet pink or magenta color by using beetroots.You can use red rose or hibiscus flower to make red color.You can use good-quality henna powder for green color. The dry, powdered henna will not leave color and you can brush it off easily. It will only leave color if it is mixed with water.All you have to do is mix food color to rice flour and add a little water to make a thick paste. Dry this paste and then grind it using a mixer to form the powder. You can also use kasturi turmeric powder instead of cooking turmeric as kasturi turmeric is more fragrant and has several beauty benefits You can use different food colours to make Holi colors. Another method is to boil marigold flower in water and leave it overnight.

The continuing cold tightened its grip over Himachal Pradesh on Sunday as the higher reaches of the state received a fresh spell of snow. However, there was widespread rainfall in the low and mid hills.The weather office here has forecast more snow and rain in the state till Monday. Shimla, which was received 15.8 mm rain, recorded a minimum temperature of 4.6C, a fall by four Celsius from Saturday. High hills in Lahaul-Spiti, Kinnaur, Kullu, Shimla, Sirmaur, Mandi and Chamba districts have been experiencing light to moderate snowfall since Friday.

25 Feb. 2018: ULTRA COLD GAS: The behaviour of an ultracold gas, consisting of thousands of atoms, which is kept in place by electromagnetic fields on a chip. There are several different quantities describing the characteristics of such a quantum gas, for example coherence lengths in the gas and correlation functions between different points in space. These parameters tell us, how closely the particles are linked by quantum mechanical effects. With our atom chip, we can even influence the time it takes the system to return to one particular state. This is obviously modern-day solipsism and not conceptually different than Brains in a Vat or the Plato's cave or the Hindu Maya.
25 Feb. 2018: WEARABLE DEVICE:

                                     Fig.14 Professor Takao Someya's  Skin-Sensor
Professor Takao Someya from the University of Tokyo unveiled what he believes will be the future of health-monitoring for our ageing society, a fully conformable and comfortable skin-wearable health monitoring system. Continuous health-monitoring with ultraflexible on-skin sensors consists of gold nanomesh-based breathable skin sensors and an elastic display that fits snugly on the skin, so recorded data (such as an electrocardiogram or temperature) can be made readily visible for the patient. Combined with a wireless communication module, this integrated biomedical sensor system could transmit biometric data to the cloud for physicians to monitor. The new integrated system combines flexible, deformable display with a light weight sensor such aselectrocardiogram,can either be sent wirelessly to a smart phone, for viewing or to a cloud for storage. The skin display consists of 16x24 array micro LEDs, and stretchable wiring mounted on a rubber sheet.

The quake hit at a relatively shallow depth of 35 km, and shallow quakes tend to be more strongly felt. A series of strong aftershocks had rattled other parts of the fault line.
February 26, 2018: Icy Blast From Siberia Sweeps Across Europe. Paris, France:  A wintry blast of freezing temperatures swept across Europe on Sunday, with a biting wind from Siberia claiming four lives and endangering the continent's homeless, with the worst yet to come. The "Beast from the East", is expected to bring chilling winds from Russia over the next week that will make it feel even colder than thermometers indicate. The cold snap has already been linked to several deaths, as well as postponing an Italian football match and causing traffic chaos. In France, where temperatures were forecast to drop to minus 10C (14F) and feel as low as minus 18C over the coming days, fears ran high for people living on the streets.
27 Feb 2018: Lithium Batteries: Kaho India Pvt. Ltd started in India in 2012 developed a device that can power three lights, one fan, one phone charger and has a socket to power a DC power television. They imported 10 devices priced at Rs.5000/- all sold, but soon realised the problem with the battery. It is expensive to replace the bettery at 40% cost, every 2-3 years, with solar panel of the unit has a life span of 25 years. Lithium batteries can be charged in 10 minutes, giving 4.5VAh per peak watt.  Lithium-ion batteries are common in home electronics. They are one of the most popular types of rechargeable batteries for portable electronics, with a high energy density, tiny memory effect and low self-discharge. A rechargeable battery will typically give you anything from two or three to as much as 10 years of useful life (depending on how often you use it and how well you look after it).The biggest issue is safety: Li-ion batteries will catch fire if they're overcharged or if an internal malfunction causes a short circuit; in both cases, the batteries heat up in what's called a "thermal runaway," eventually catching fire or exploding. That problem is solved with a built-in circuit breaker, known as a current interrupt device or CID.

The solid inner core is thought to be a mass of iron about the size of the moon that is heated to several thousand degrees Fahrenheit. Heat radiated by this inner core builds up at its boundary with Earth's liquid outer core, causing the fluid there to expand. When it expands it becomes a little less dense [and more] buoyant. So it starts to rise. That's convection. Hot fluid rises, then cools off and sinks again. The convection generates an electric current and, as a result, a magnetic field. Additional currents are created as Earth cools. Some of the molten iron solidifies onto the inner core, releasing lighter material in the process. The rotation of the Earth also generates forces that curve the flow of fluid as it rises, twisting the magnetic field. All of these currents constantly replenish the magnetic field, a maintenance process that prevents it from decaying. Typically each newly generated field lines up in the direction of the existing magnetic field. But every now and again, some force will cause the new field to line up in the opposite direction. This process can lead to a net weakening of Earth's magnetic field.

NEW DELHI –  India's finance minister has announced a federal budget with a string of populist giveaways, from free cooking gas to a health plan for the poor, in an attempt to woo voters ahead of national elections next year. 

Feb 1, 2018: LEGAZPI, Philippines –  Lava flowing out a Philippine volcano has spread up to 3.6 km (2.2 miles) since it began intense eruptions more than two weeks ago. Streaks of red glowed atop the summit of Mount Mayon during a mild eruption Thursday morning as the moon set, hours after a blue moon and supermoon coincided with a lunar eclipse.The eruptions fed lava flows in two areas that already exceed 3 km (1.8 miles). The danger zone around Mayon extends 8 km (5 miles), though authorities have struggled to keep villagers from returning to check on their homes and farms.
02 Feb. 208: New Delhi:  General David L Goldfein, Chief of Staff of US Air Force will fly on India's indigenous light combat aircraft, the Tejas, this morning, a special flight that will take off from the Jodhpur Air Force Station that signals the soaring ties between the two air forces. The top ranking US military officer had reached India on Thursday on an official visit to deepen relations.
3 Feb 2018: MAYA CIVILIZATION:

Fig.1   Maya civilization 

Aerial laser mapping detects thousands of hidden structures in Peten region, suggesting its population was millions more than previously thought. The 810 square miles (2,100 square kilometers) of mapping done vastly expands the area that was intensively occupied by the Maya, whose culture flourished between roughly 1,000 BC and 900 AD. Researchers using a high-tech aerial mapping technique have found tens of thousands of previously undetected Mayan houses, buildings, defence works and pyramids in the dense jungle of Guatemala’s Peten region, suggesting that millions more people lived there than previously thoughtTheir descendants still live in the region. The mapping detected about 60,000 individual structures, including four major Mayan ceremonial centres with plazas and pyramids. Belize’s Great Blue Hole, a 400ft-deep cave in a barrier reef, that supports the theory that drought and climate conditions pushed the Mayans from a regional power to a smattering of rival survivors and finally a virtually lost civilization.he researchers took sediment samples from both the ancient sinkhole and the central Belize lagoon corresponding to the era of the Mayan decline, between 800 and 1000 AD.

Aftershocks continue to rattle Taiwan after a strong earthquake that killed at least four people and injured more than 200 others. About 143 of its residents remain unaccounted for. People reported feeling the quake in the island's capital, Taipei, more than 160km (100 miles) away. Taiwan has been rocked by more than 100 earthquakes so far this month.
A NOVEL AND EFFECTIVE WAY: Biosynthesis of gold nanoparticles (AuNPs) from Pseudomonas aeruginosa and Rhodopseudomonas capsulata bacteria is considered to be a novel, effective and eco-friendly method. The important parameter, which controls the size and shape of AuNPs, was pH value. The R. capsulata biomass and aqueous HAuCl4 solution were incubated at pH values ranging from 7 to 4. The AuNPs were characterized by UV–Vis whose absorbance measured at 540 nm followed by transmission electron microscopy showed the formation of AuNPs in the range of 20–80 nm in diameter at pH 6.5. Scanning electron microscopy revealed the AuNPs ranging from 50 to 70 nm, Fourier transform infrared spectroscopy confirmed the formation of AuNPs in the range of 4,000–400 cm−1. The results demonstrated that spherical AuNPs in the range of 10–20 nm were observed at pH value of 7 whereas a number of nanoplates were observed at pH 4. Hence, the present study enlightens on the green chemistry approach on the production of AuNPs using microorganisms.
A metal-gobbling bacteria manages to ingest toxic metallic compounds and still thrive, producing tiny gold nuggets as a side-effect, scientists have found. High concentrations of heavy metals, like copper and gold, are toxic for most living creatures, researchers said. However, that is not the case for the bacterium C metallidurans, which has found a way to extract valuable trace elements from a compound of heavy metals without poisoning itself. The bacteria produces tiny gold nuggets as a side-effect, according to the study published in the journal Metallomics.
A team of researchers from Martin Luther University Halle-Wittenberg (MLU) and the Technical University of Munich (TUM) in Germany has discovered the molecular processes that take place inside the bacteria. The rod-shaped bacterium C metallidurans primarily lives in soils that are enriched with numerous heavy metals. Over time some minerals break down in the soil and release toxic heavy metals and hydrogen into their environment. There is enough hydrogen to conserve energy and nearly no competition. If an organism chooses to survive here, it has to find a way to protect itself from these toxic substances. The gold enters the bacteria the same way as copper, which is a vital trace element for C metallidurans, however it is toxic in large quantities.
Gold and Copper: When the copper and gold particles come into contact with the bacteria, a range of chemical processes occur: Copper, which usually occurs in a form that is difficult to be taken up, is converted to a form that is considerably easier for the bacterium to import and thus is able to reach the interior of the cell. The same happens to the gold compounds. When too much copper has accumulated inside the bacteria, it is normally pumped out by the enzyme CupA. However, when gold compounds are also present, the enzyme is suppressed and the toxic copper and gold compounds remain inside the cell. Copper and gold combined are actually more toxic than when they appear on their own. To solve this problem, the bacteria activate another enzyme - CopA. This enzyme transforms the copper and gold compounds into their originally difficult to absorb forms. This assures that fewer copper and gold compounds enter the cellular interior. The bacterium is poisoned less and the enzyme that pumps out the copper can dispose of the excess copper unimpeded. Another consequence: the gold compounds that are difficult to absorb transform in the outer area of the cell into harmless gold nuggets only a few nanometres in size. In nature, C metallidurans plays a key role in the formation of so-called secondary gold, which emerges following the breakdown of primary, geologically created, ancient gold ores. It transforms the toxic gold particles formed by the weathering process into harmless gold particles, thereby producing gold nuggets.
7 Feb. 2018: SUNSPOT MUTUAL MAGNETIC FIELD OF  6250G: Most powerful solar magnetic field measured by Japanese Astronomers, on the surface of the Sun. As per a study published in Astrophysical Journal, NAOJ determined the powerful magnetic field as a result of gas outflow, from one sunspot pushing to another sunspot. After tracking the same sunspot for several days, HINODE revealed that the strong field was always located at the boundary between the bright region and the umbra. The horizontal gas flows along the direction of the magnetic fields, on the other hand, turned down into the Sun when they reached the strong-field area. The bright region with the strong field, therefore, is a penumbra belonging to the southern umbra. The horizontal gas flows from the southern umbra compressed the fields near the other umbra, and enhanced the field strength to more than 6,000 gauss, according to astronomers. Japanese report clear evidence of the magnetic field of 6250 G, which is the strongest field among Stokes I profiles with clear Zeeman splitting ever observed on the Sun. The field was almost parallel to the solar surface and located in a bright region sandwiched by two opposite-polarity umbrae. Using a time series of spectral data sets, we discuss the formation process of the super-strong field and suggest that this strong field region was generated as a result of compression of one umbra pushed by the horizontal flow from the other umbra,
Feb. 7, 2018: Toronto: Only one type of virus in different parts of the World, occupying the troposphere, and travelling thousands of kilometres, are falling on the Earth. Every square meter about 800 million viruses, accumulating in the troposphere, falling down due to rains.

12 Feb. 2018: Himalayan Springs: A government report asserts that a majority of Himalayan low-water springs have dried up and reached critical levels in some states. Half of the perennial springs have already dried up or become seasonal, causing acute to a report submitted by the DST,to the NITI Aayog. As per estimates there are five million springs in India. Fading springs are a result of erratic rainfall patterns, increased water demand, seismic activity, changing land use patterns and ecological degradation due to infrastructural development. Spring management is slowly becoming a nationally pertinent problem.
Feb 12, 2018, 02.30 AM IST: Hailstorm kills 2, damages crops in parts of state. Hailstorm over central parts of Maharashtra, Marathwada and parts of Vidarbha region claimed two lives and caused extensive damage to crops on Sunday.According to residents, parts of Jalna district “resembled Kashmir”. “There are ice cubes everywhere. The roads have become slippery and I witnessed several bikers falling down,” said Ajit Patil. The temperature had dropped down and people are likely to fall sick. The ice cubes are still lying in fields.”
February 13, 2018 20:39 IST: Water crisis is here: World's 12 major cities likely to dry up soon, Bangalore 2nd most water-stressed: The world's freshwater reserves are depleting fast, putting major cities at risk of running out of drinking water soon.Sau Paulo in Brazil almost ran out of water in 2015 after the main reservoir fell below four percent of its capacity. The water bodies in Bangalore are so polluted that not a single lake can provide drinking water. China holds 20 percent of the world's population but only seven percent of its drinking water. While Egypt was once known for its large rivers, it is now in the water scarcity list as the River Nile is struggling to survive. Indonesia's capital Jakarta is the sixth city that is expected to run out of water in a few decades. Less than half of the 10 million Jakarta residents have access to piped water. Official records say that 35 percent to 60 percent of Russia's total drinking water is unsanitary and unfit for consumption. Turkey government has already stated in 2016 that Istanbul is in major water stress after its per capita supply fell below 1,700 cubic meters. The Mexico city residents have faced water scarcity for a long time as reports suggest only one in five people get a few hours of tap water per week and only 20 percent has running water for a few hours in a day. Although London is believed to have a large amount of rainfall throughout the year, the city is struggling to cope with its drinking water problems. The capital of England draws 80 percent of its water from the Thames and Lea rivers.Tokyo is another city that experiences a lot of rainfall but fails to collect the rainwater for further utilization, in spite of at least 750 buildings having a rainwater collection system.People think of beaches and fun when they hear of Miami, but the party city in Florida, US is also suffering from major water scarcity. Saltwater from the Atlantic Ocean is contaminating the Biscayne Aquifer.
 Feb 13, 2018, 04:02 PM IST: Cyclone Gita wreaks havoc in Tonga's capital, Parliament flattened, homes wrecked.There were no confirmed reports of deaths from the Category 4 storm that bought winds of around 200 km (125 miles) per hour, but there were a lot of injured people, some seriously.The cyclone was heading towards Fiji's southern islands on Tuesday, with some forecasts reporting it intensifying towards a Category 5 storm. Fijian Prime Minister Frank Bainimarama warned residents to "heed warnings and prepare", although the storm is expected to bypass heavily populated areas. Gita had pummelled Samoa and American Samoa, about 900 km (560 miles) to the northeast, over the weekend, flooding the Samoan capital, Apia. They have been through cyclones before, but this is the biggest cyclone this island has had for at least 60 odd years.

2018-02-15 16:22:02: Electrons bouncing across Earth’s magnetic field cause Northern Lights, with the onset of a new satellite with advanced measuring tools, have identified that this wonderful phenomenon is caused by the interaction between electrons and plasma waves.  Electrons bouncing across Earth’s magnetic field cause Northern Lights! (Source: NASA). Scientists have observed the cause of the Northern Lights for the very first time. According to them, the shower of electrons bouncing across the Earth’s magnetic field cause the Aurora Borealis, the colourful phenomenon which is commonly known as the Northern Lights. Scientists, with the onset of a new satellite with advanced measuring tools, have identified that this wonderful phenomenon is caused by the interaction between electrons and plasma waves. This interaction takes place in the Earth’s magnetosphere, the region in which the behaviour of the electric particles is governed by the planet’s magnetic field. Satoshi Kasahara, of Tokyo in Japan said  Auroral sub storms are caused by global reconfiguration in the magnetosphere, which releases stored solar wind energy.  They are characterized by auroral brightening from dusk to midnight, followed by violent motions of distinct auroral arcs that eventually break up, and emerge as diffuse, pulsating auroral patches at dawn. The phenomenon happens when a specific type of plasma waves, called the chorus waves, rain electrons in the upper atmosphere. This stabilizes the system and gives off a colourful light as the electrons fall.
