Are Zombies Real?

One of the most mysterious urban legends of our time, Zombie has once again started creating a lot of buzz inside the world of science and politics as well. Recently, some of the US’s politicians (most from the Illinois) have cautioned citizens and law enforcement agencies to take their Zombie preparedness ability more seriously.

Last year, the month of October was marked as the “Zombie Preparedness Month.” Reportedly, it is being said that intelligence inputs might have got some inputs that prompted the state authorities to raise awareness of the people about Zombies. The Illinois state assembly put forward a house resolution (HR 0030) that asked people of Illinois to stay well prepared for Zombies; by doing so they can be in a better position to handle nature’s fury and other disasters as well.

The resolution was approved by the house a few days back. The bill also exposed America’s preparedness towards combating nature’s fury. Few states even lack the modus operandi to distribute food, water and medicine supply to affected people during a natural disaster

The debate was actually regarding America’s capacity to fight nature’s wrath but Rep. Steven Anderson, R-Geneva, made the conversation more interesting by raising the question that which type of Zombie to be used for natural disaster preparedness? He argued that Zombies portrayed on “Z Nation” are faster but those on “The Walking Dead” are more organised.

Scientific Evidence to Zombie’s Existence

Believe it or not, Zombies are real! Science is notorious for doing things that we couldn’t even dream of. Dr Wade Davis, a well known scientist, has learned the “art of making Zombie” using mysterious Zombie juice  and toad skin. He learnt the art from a Vodoo practitioner in Haiti.

1) Zombies are created by Vodoo priests belonging to Bizango secret societies.

2) Zombification or creating someone a Zombie is an ultimate form of punishment to a culprit or convict under Bizango societies.

In his book, “Passage of Darkness (1988)”, the scientist claimed to have found the reality of Zombies. He concluded that by putting on toad skin all over the body and consuming a poisonous substance, the person goes insane and stays in an inebriated state for a long time – mostly for life long time.

 What Does a Zombie Do?

They mystery of Zombies has always made people curious. Zombie basically denotes a dead man having an ability to walk in an eerie manner. They suck blood from humans. The English word “Zombie” first came to use in 1819 when the Brazilian poet Robert Southey mentioned the term Zombi in his literary work.

Zombie is largely categorized as a work of fiction with no existence of its own. They eat raw meat of humans and animals. According to the Haitian folklore, whoever commits suicide – never gets salvation. Their souls could neither enter a new human body nor could it escape from the world. They continue to stay in a half-human and half-dead state forever!

Earth Finds its 8th Continent in Zealandia: Say Scientists

Until now, the earth has seven continents; Africa, Antarctica, Asia, Australia, Europe, Latin America and North America. But the latest news confirmed that scientists have now unveiled the latest mystery surrounding the eighth continent Zealandia.

Researchers have now argued that New Caledonia and New Zealand are not just an island chain, but a gigantic part of 5-million-square kilometer slab of continental crust (excluding Australia) – submerged under water.

Prominent geologist Luyendyk discovered the term Zealandia for the newly-discovered continent as early as 1995 because of its closer proximity to New Zealand region. It covers the regions of New Zealand, New Caledonia and a collection of crust that broke off from the ancient Gondwana region. According to an estimate, around 95 per cent of Zealandia is currently submerged underwater in the Southwest Pacific Ocean.

Criteria for a Land to Constitute as a Continent

  • Land that is high from the sea floor.
  • The presence of three types of rocks; Igneous, Metamorphic and sedimentary. Igneous rocks are formed out of volcanic eruption, metamorphic rocks are formed due to intense heat and pressure, and sedimentary rocks come to form out of erosion.
  • Thicker crust surrounding the sea floor.
  • Having a considerable size of an area.

Eventually, Luyedyk came to conclusion with the term Zealandia for the area that is expected to be continental with a collection of micro continents. The recent study suggests that Zealandia is a part of a unified region. The area is estimated to be even bigger than India. More research into the subject is still awaited.

Some More Interesting Facts about Zealandia

Zealandia consists of two plates; the Pacific plate and the Australian Plate. “I’m from California, and it has a plate boundary going through it. In millions of years, the western part will be up near Alaska. Does that make it not part of North America? No,” said Luyendyk.

Today, only five percent of the Zealandia land is visible. The process of classifying Zealandia as a continent could take a few more years after due observation by the geoscientists.

The country that will be hot topic among scientist is New Zealand. As it is still to be determined that what part of New Zealand will constitute Zealandia and what part will continue to be counted as a territory of New Zealand – the nation?

Zealandia covers parts of Norfolk Island, the Lord Howe Island group, New Zealand and Middleton reefs. It is believed that Zealandia broke away from Gondwana some 80 million years back. Over the last two decades, geologists worldwide are trying to include Zealandia as an independent and well-recognised Continent. If their proposal is approved, Zealandia is set to become the world’s eighth and smallest continent.

Top 6 Impacts of Music on Human Life

Top 6 Impacts of Music on Human Life

Ever since the evolution of mankind on this planet, music has continued to remain a vital force behind the unity of the people. People feel more connected to each other whenever like-minded songs are played out. Whether you take an example of a song or simply a musical composition, both will have an underlying positive message that is to motivate the listeners and drive them to do something big for the nation.

Hardly, you will find someone who doesn’t like music at all. Most of us love music in one way or other. According to neuroscientist Daniel J Levitin, “By better understanding what music is and where it comes from, we may be able to better understand our motives, fears, desires, memories and even communication in the broadest sense”. He tried to analyse how music impacts our minds, body and souls.

Music soothes our hearts. It refreshes our minds and in fact, music can take us to a different world altogether. It makes us happy and keeps us stress-free too. Such is the charisma of music. Music impacts our lives in various ways.

Top 6 most important Impacts of music in Human life.

Music and Health: It might sound surreal but music has a lot of positive. Listening to soothing tracks help us to treat anxiety while keeping our mood relaxed and calm. It is useful for therapeutic purpose too. Music also keeps us in cheerful and good spirit too.

Music makes us smart: Music improves our personality. A beautiful track in moderate volume makes us smart while igniting our passions for creativity. In some rarest cases, music helps reviving people sustaining brain damages. One theory also says that those who learn music at a young age develops strong vocabulary powers and can easily handle non-verbal reasoning too.

Sad Music is Effective too: Sad music has its own relevance. It evokes two kinds of emotions in human beings; felt emotions and perceived emotions. Sometimes, sad music makes a person feel more romantic and inspired than ever before.

Music Can Strengthen Physical Relationship: Believe it or not, music can prove wonderful to enhance your libido factor. Music can definitely strengthen men having low testosterone to increase serotonin levels and perform better at bed in night.

Music can boost your x-factor too: Music is definitely a mood buster. People can listen to various musical tracks and stay in good mood. However, various magazines also countered the argument saying happiness depends upon a number of things like personal relationship, health and many other factors. However, even now it’s well known how listening to good music can enhance one’s personality.

Music as an expression of emotions and ideas: Music is an effective mode of communication. It reveals how a man feels at a certain time. The inspirational songs motivate the listeners and bring out the best in them at a given time.

Dentists Found a New Way to Repair Teeth Naturally Using Alzheimer’s Drugs

Image source: Telegraph.co.uk

As we grow old, out natural capacity of the tooth also decreases. Sometimes, this leads to replacement of teeth. In that case, inorganic cements based on calcium or silicon-based mineral aggregates are filled. But often the cement fails to give that much normal mineral volume which is necessary in the gum. Also they often get infected resulting in more problems for the patient.

In case of a problem due to infection – using cements or fillings often lead to infections – which complicate the problem. If the infection is big then dentists finally extract the tooth out of the mouth.

So, scientists have now come forward with a natural solution. They have now found the innovative way of natural formation of reparative dentine by mobilization of stem cells in the tooth pulp.

The process involves delivering low dosage of glycogen synthase kinase (GSK-3) antagonists through collagen sponges that promote the restoration of dentine. After a few days, the sponge is degraded leading to replacement of complete and effective natural repair. It could do wonder in the field of dental science.

New Research on Dentine at King’s College

A team of researchers at King’s College in London has found another method of stimulating the renewal of living stem cells in tooth pulp through Alzheimer’s drug. Due to infection, the inner pulp of tooth can get infected. In order to prevent so, a thin band of dentine is applied to the tooth pulp to disinfect and seal the same. But sometime this remains far from satisfactory and requires more innovative and appropriate dental implant to correct the same.

A feature published in scientific reports stated that researchers from the Dental Institute at King’s College, London, have found a new remedy with stimulation of stem cells located within the pulp of the tooth to generate new dentine. It reduces the dependence upon external substance and methods like filings or cements.

Professor Paul Sharpe from King’s College London stated, “The simplicity of our approach makes it ideal as a clinical dental product for the natural treatment of large cavities, by providing both pulp protection and restoring dentine. In addition, using a drug that has already been tested in clinical trials for Alzheimer’s disease provides a real opportunity to get this dental treatment quickly into clinics, he added further.

Experts feel this is an exhaustive process. It will help to enhance the natural repairing ability of the teeth in regard to large cavities. The stimulation of the renewal of the stem cells will include Tideglusib (Substance) which is also useful to cure Alzheimer’s disease. Hope this new invention will help people get their dental implant done in a more natural and safer way.

Scientists Discovered Time Crystals: Latest form of Matter

 

In an interesting scientific development, two groups of scientists have discovered a new phase of matter called time crystals. Scientists from Harvard University and the University of Maryland have invented the first-ever time crystals. This newest form of matter will have its applications in quantum computers.

Time crystals have an atomic structure that repeats in time on periodic basis like tapping Jell-O to jiggle. The time crystals are similar to the liquid or gaseous state of ice. According to Yao (scientist) of UC Berkeley group, “time crystals are a new phase of matter, period and first example of non-equilibrium matter”. In fact, time crystals have conga line of 10 ytterbium ions whose electrons interact in a similar way how qubit systems work inside quantum computers.

The idea of time crystals was first conceived by Nobel Laureate Frank Wilczek in the year 2012. This subject then again got the limelight last year when physicists at Princeton University, the US proved that such crystal can be easily made. In fact, the nano atoms within the time crystals oscillate sans energy making it one of the isolated cases of non-equilibrium matter.

When it comes to normal crystals like diamonds, these have an atomic lattice or array of atoms attached to it – that repeats in space. Time crystals have added a new dimension to the study of matter. For the last few decades together scientists have been zeroing in on equilibrium matters like insulators and metals, but with the discovery of time crystals – this trend is set to change. Now, scientists will also give enough attention to non-equilibrium matters as well.

How does Time Crystal Functions?

Scientists claimed that time crystals break time symmetry. The magnetic field created by the crystals drive ytterbium atoms producing a typical repetition in it which otherwise won’t happen.

“You have some periodic driver that has a period ‘T’, but the system somehow synchronizes so that you observe the system oscillating with a period that is larger than ‘T’”, a scientist studying time crystals explained. This research on Time Crystals was well supported by the Air Force Office of Scientific Research, the Gordon and Betty Moore Foundation and the concerned varsities.

Time crystals resemble jelly. It jiggles on tapping but otherwise remains motionless and without energy for most of the time. It is definitely a non-equilibrium matter. This prompted Yao and his team to come out with a detailed blueprint and hypothesis that accelerated massive research oin this field by other scientists as well. Yao’s blueprint was first published in Physical Review Letters.

The Source of Fast Radio Bursts is Discovered

Image source: www.cmu.edu

In a successful observation by the group of astronauts, the source of a Fast Radio Bursts (FRB) is found. The FRB as per its nomenclature releases cosmic radio waves to the universe. These spark for milliseconds in the dwarf galaxy located around three-billion light-years away from the planet earth.

Fast Radio Bursts created headlines in 2007 for the first time after a lot of research on the subject that began in 2001. Earlier, there were doubts about the origin of FRB with many scientists were confused whether these rays originated within the galaxy or outside it.

Until now, around 18 fast radio bursts have already been found. Last year, a team of astronomers from the US and Canada made an in-depth study into the subject for 6 months to find the source of FRB 121102 (latest code given to Fast Radio Outbursts).

According to the team of astronauts who conducted the study, it was a herculean task. They had to use the Very Large Array (VLA) radio telescope to get a precise location of FRB 121102 in the open universe.

Shriharsh Tendulkar of McGill University led the team in Hawaii when his team was searching the source of FRB 121102. They were unclear whether it was coming from a galaxy or a star, but later on, it was found that the source of FRB was similar to star – tiniest speck of light. In the words of Tendulkar, “it’s 100 million times fainter than the faintest object visible to the naked eye.”

What does the Fast Radio Bursts Research say?

The astronomers found that FRB 121102 was located in a dwarf galaxy with stars all around. Earlier, they believed that FRBs would be found in larger galaxies but the latest research proved them wrong. It is assumed that some billions of years ago, a series of fast bright bursts of radio waves entered into the open space, and since then it kept on radiating bright lights.

Initially, FRB 121102 travelled all across the universe and until scientist noticed them properly in 2007. In 2015, around 16 flashes were observed and then again in 2016, nine more appeared. Relentless research finally disclosed that FRBs originate from the minuscule galaxy amidst little heavenly bodies. Scientists have unraveled many things about universe in the past but for more information on FRBs – we have to wait more – until more and more details about the subject are being unearthed by scientists. The subject matter of Fast radio bursts is still shrouded in mystery.

Scientists’ Tryst with Fast Radio Bursts

It was an accidental discovery. Scientist Duncan Lorimer in 2007 was searching something related to Pulsars – when he noticed the FRB that flashed occasionally into the open space. But it was brighter than pulsars. This marked the start of the minute research into FRBs.

According to Shami Chatterjee, the researcher into the subject, “This is a good place to go fishing because you’re more likely to see a fast radio burst at this spot,” says Chatterjee.

More study will be done to dig out further details of FRBs. It will help scientists to know if a bunch of FRBs has similar characteristics and physical fundamentals. Then it will make clear that why and what inside a dwarf galaxy lead to repeating of fast radio bursts?

Inkjet Printers Vs Laser Printers: Which One You Should Buy?

Image source: inkpal.com

Every time we decide to purchase a brand new printer the first thing that comes to our minds is whether to purchase a laser printer or inkjet printers? In case of laser printers, toner cartridge is used for the print while in inkjet printers liquid ink is used through microscopic nozzles to ensure that print is done properly. Both have their own advantages and disadvantages.

The basic difference between inkjet printers and laser printers is the color prints. A laser printer can only print black and white (mono) materials while inkjet printers can easily print colorful stuff.

Top 5 Differences between Inkjet Printers and Laser Printers

Price of the machine: Nowadays, both Laser Printers and Inkjet Printers are priced competitively. In fact, they are sold at almost the similar price.

Price per print: Printing black and white copies with laser prints costs far lesser than doing the same using inkjet printers

Color Print: Laser printers don’t support printing of colorful copies while inkjet printers easily support so. Even if the new color laser prints support color copies – these cost too much.

Print speed: A laser printer can print up to 17 black and white copies in a minute while inkjet printers can just print around 7 (B&W) copies per minute.

Multipurpose Use: If you wish to do too many things like print scan and copy, then inkjet printers are the best. But if you wish to use printer only for printing then Laser Printer is the best option.

Inkjet Printer: Features at a Glance

  • It supports high quality photo printing.
  • These printers are smaller, portable and lightweight.
  • It can print on glossy papers with superior texture
  • It can be instantly switched on put to use immediately. It takes very less time to warm up.

 

Disadvantages

  • The ink is little more expensive than toner ink.
  • It requires frequent maintenance to get superior print quality.
  • The machine speed is little lower as compared to lasers.
  • Inkjet printers can be problematic when you wish to print more copies.

Laser Printer: Feature at a Glance

  • It gives correct black impression on print.
  • Apt for printing high volume of pages in black and white.
  • Costing per print is far lesser in laser printer than inkjet printers.

Disadvantages

  • It takes relatively more time to get warm up than inkjet printers.
  • Toner leakage is quite possible in Laser printers which could completely destroy the pages in the output sheet.
  • It can’t handle a variety of pages that Inkjets do.
  • These printers weigh more and are difficult to travel with.
  • Photo quality in laser prints is not that much good as compared to inkjets.

The differences are clear. Both Laser and inkjet printers have their own merits and demerits. Now, which one you will buy completely depends upon your own requirement and needs.

Well, if you wish to print colorful photos using your printer and you do not have bulk printing needs then you buying a multipurpose inkjet printer could be the apt option before you. But if you wish to use the printer for commercial purposes and heavy use, then go for monochromatic laser printers.

Can Trump Prevent North Korea’s Crude Missile Test on US Land?

Image Source: Reuters

Amid brewing tension between the North Korea and the United States (US), a question has come to fore that can the Trump-led US prevent or go for a preemptive strike if North Korea launches its ICBM (Intercontinental Ballistic Missiles) to the mainland of the US? Well, nobody has a definite answer to it.

Recently, a North Korean official announced that the Kim Jong-Un is building up his nuclear arsenal and defense capability to thwart any attack coming from the American side. There is a clear-cut ideological difference between the capitalist-democratic US and the Communist North Korea, but both countries are tight-lipped about their defense strategy.

However, what could be clearly counted as a matter of provocation, a North Korean official has recently said that their ICBM could easily hit the US cities like Los Angeles or New York. Once the news reached the White House, incumbent president Donald Trump rebuked the claim saying it won’t happen. The undercurrent of the President’s message is clear; if North Korea dares so then the US has many alternative options to stop the same.

But North Korea is relentlessly improving its nuclear capability and American sources quoted that Kim Jung-Un government has launched a satellite into orbit a few months back named Unha rocket. It has a range of around 10,000 Km at one go. It could easily cover 13,000 kilometers to reach into the US mainland from North Korea.

Last year, North Korea launched KN-08 ballistic missile. North Korea revealed pictures of its newly launched missile engine which could launch a nuclear attack to the US. However, US State Department official stated that North Korean ICBM doesn’t have that the technology to fit a weapon atop it.

Options before the US to Subdue North Korea’s Nuclear Ambition

  • Launch a massive airstrike and sending bombers over North Korea to demolish missile launch pad. However, this strategy must be exercised as the last option.
  • Initiate proper diplomacy and engage in bilateral dialogues via Sweden to ensure that both nations won’t go for a war.
  • The US can keep NATO and its allies informed about the possible North Korea strike on the US – so that they can stay cautious.
  • Whenever ICBM is launched from North Korea, the US can stop it by using ground-based interceptor missiles. It has a reserve in Alaska, Vandenberg and other places.
  • The US is developing its anti-missile Terminal High Altitude Area Defense (THAAD) system to intercept any missile attack emanating from North Korea.
  • The US should launch a diplomatic campaign to isolate North Korea while taking other countries into confidence, must ask North Korean regime to shun its nuclear armament desires.

In recent times, North Korea-US relations have taken a backseat because of Kim Jong-Un’s continued testing of nuclear weapons. Last year on January 6, 2016, North Korea conducted its fourth nuclear test successfully which raised eyebrows of several nations including the erstwhile South Korea and the US as well.

Then in the same year, US put North Korea’s head Kim Jong-Un on its list of sanctioned individuals which Pyongyang perceived as a direct threat of war by the US on North Korea. It would be interesting to see how both nations would de-escalate the tensions between them – the world hopes that US-North Korea won’t go that far and ultimately peace prevails.
