New Year’s eve–especially in the Philippines– is a love-hate relationship. Basically, we are thrilled at the joy of welcoming a brand new year full of brand new experiences, opportunities, blessings and possibilities. What we do not like however is the impending threat to our beloved animals we love and care for so dearly.

Yes, it’s that time of year again, when our furry little love bugs would hide and scurry their furry posteriors  in the closet, behind the fridge or anywhere they feel safe.

Why do dogs hate firecrackers?

Based from what we learned from an article on PoochPalsPetCare (.com) dogs hate firecrackers obviously because of the high intensity sound. Dogs have very sensitive hearing and they hear firecrackers 10x the intensity of how us humans hear it. Also, we humans understand it, the sound and all, based from society. We also connect it to something cheerful and joyful but our pets, do not.

We found this very helpful tip online:

YAAAAAY!!! Try this little trick even through thunderstorms and such and let us know if it works!

What are other tips you can suggest for our pets to remain calm and help them through New Year’s?



Holograms are awesome. They can make our heroes appear in 3D in front of us from thousands of kilometres away, whether it's Stephen Hawking appearing in Sydney earlier this year from the comfort of his home in London, or Tupac appearing at Coachella from, um, his elaborate hide-out in Cuba? We can even touch 3D holograms now, thanks to researchers in Japan who used powerful, ultra-quick lasers to produce tiny holograms that can be physically felt and respond to human touch. But what about playing around with holograms in the comfort of our own homes?

The awesome video above by Mrwhosetheboss on YouTube shows you how to create amazing 3D holograms that can be projected from your smartphone.

First off, you'll need to collect a few things:

Graph paper
CD case
Tape or superglue
Pen
Scissors
Smartphone
Knife or glass cutter

First you'll need to draw up a perfect rhombus shape on your graph paper. You can get the required dimensions from the video. Next, take off the sides of the CD case, place the rhombus template on top, and cut out the shape. Once you've got your first rhombus cut out, you can use this as a template to cut out three more.

Fasten the four plastic rhombus shapes together in an open vase shape using your tape - glue can work too, but the video recommends tape - and place it on your smartphone screen. To start projecting holograms, you'll need to load up hologram-specific videos from YouTube or on your browser, and Mrwhosetheboss links to a few of these on his YouTube page. Turn off the lights and you'll see a full, 360-degree animated visual. We can't wait to try it.

The record-breaking lasers were created by physicists from Imperial College London in the UK and the Friedrich Schiller University Jena in Germany, using tiny wires made of zinc oxide placed on a silver surface.

“While the fastest lasers typically need several nanoseconds for one cycle our semiconductor nano-laser only needs less than a picosecond and is therefore a thousand times faster,“ said Carsten Ronning, one of the researchers involved from the Friedrich Schiller University Jena, in a press release.

This breakthrough could lead to faster internet connections and data transfer, and is published in Nature Physics.

“Turning a laser on and off quicker means more information carrying 1s and 0s per second, allowing much faster data communications. In fact, these lasers are so much faster than conventional electronics that we had to develop an optical switching method to measure their speed,” said lead author of the research Themis Sidiropoulos from the Imperial College London.

Traditionally in these types of semiconductor lasers, the nanowires are placed on a glass surface - but by using the silver surface they were able to speed up the light by “squeezing it”.

The zinc oxide nanowires are only 120 nanometres in diameter - around a thousandth of the diameter of a strand of human hair - and can already pulse out light at an impressive rate.

But by using features on silver called surface plasmons, which are wave-like motions of excited electrons found at the surface of metals, the physicists could squeeze the light into a much smaller space inside the laser, which meant that it also interacted more strongly with the zinc oxide nanowires.

This stronger interaction sped up the rate at which the lasers could be turned on and off by 10 times, and makes them the fastest on record.

"Most likely we also achieved the maximum possible speed, at which such a semiconductor laser can be operated,” said Robert Röder, a PhD student involved in the project in a press release.

The laser is also stable at room temperature, which makes it perfect for use in internet and communication systems. It could also be used to help detect single molecules or microbes in medical diagnostics.

“This work is so exciting because we are engineering the interaction of light and matter to drive light generation in materials much faster than it occurs naturally,” said senior author and Imperial College London researcher Rupert Oulton in a press release. “When we first started working on this, I would have been happy to speed up switching speeds to a picosecond, which is one trillionth of a second. But we’ve managed to go even faster, to the point where the properties of the material itself set a speed limit.”
Scientists in Japan have set the record for the most powerful laser ever fired, producing a 2 petawatt pulse - that’s 2 quadrillion watts - using a device known as the Laser for Fast Ignition Experiment (LFEX). While they could only sustain it for a mere one-trillionth of a second, the team claims it had a concentrated energy equivalent of 1,000 times the world's electricity consumption.

Located at Osaka University, the LFEX laser projector is about 100 metres long, and combines four carefully positioned glass 'lamps' to amplify a laser beam over and over as it travels along the length of the device. This set-up allowed the team to produce an incredibly concentrated amount of power while consuming only a couple hundred joules of energy, which is about as much power your microwave uses in 2 seconds.

"With heated competition in the world to improve the performance of lasers, our goal now is to increase our output to 10 petawatts," one of the team Junji Kawanaka, an electrical engineer at Osaka University, said in a statement.

Is this awesome? Yep, but it’s not going to be shooting down satellites or blowing up planets Death Star-style any time soon. While earlier this year Lockheed Martin was able to burn a hole through a car 1.6 km down the road using a mere 30-kilowatt laser, and German company MBDA Deutschland reportedly knocked drones out of the sky from 3 kilometres away using a 40-kilowatt laser, Japan’s LFEX beam couldn’t even come close to this.

"If one wanted to destroy a satellite, the Japanese LFEX laser would not be the answer, as it would not propagate far through the atmosphere - even if it could be pointed towards the satellite," Michael Donovan, the associate director of Texas Petawatt Laser program in the US, told Patrick Tucker at Defence One. "The higher you get, the thinner the atmosphere. So a laser launched in space could propagate, but a petawatt laser is too large to economically launch into space."

The Texas Petawatt Laser is the only comparable device in the world right now, able to produce a 1 petawatt laser pulse.

So why is it that a 30-kilowatt laser fired over more than a kilometre can do so much damage when a 2 petawatt blast can’t even make it into space? "Turns out that petawatt lasers only work in a vacuum, because they ionise the air that they come in contact with," says Tucker. "That’s the difference between a 'high-energy laser' of the military variety versus a 'peak power laser', like the one in Osaka."

Not that it hasn’t got people comparing the LFEX laser to the Death Star super-weapon in the Star Wars universe. But let’s be realistic here, we’re gonna need a whole lot more power to blow up a planet the size of Alderaan. As Matt Springer explains at his blog, Built on Facts, if we’re using Earth as an example, a laser powerful enough to blow it up would have have to produce around 2.2 x 1032 joules of energy.

"That’s a preposterously huge amount of energy! It’s a solid week of the Sun’s entire power output," says Springer. "Dumping it in about a single second, as required to blow up Alderaan, is a very, very impressive feat. Doubly so when you take into account the fact that the binding energy is just enough to dissociate the planet into a diffuse cloud. If you want to actually blow the thing up into pieces flying out at many times escape velocity, you need much more energy."

When we compare 2.2 x 1032 joules of energy with the couple of hundred joules being produced by LFEX right now, I think it’s safe to say the Death Star will be stuck in science fiction for a while yet.
Reports of influenza epidemics and gastrointestinal viruses appear every couple of weeks on the news. In most cases, it’s a matter of insufficient hygiene and the spread of germs. The problem is that we can not see these microscopic threats with the naked eye. But a smartphone can shine some light on the truth; literally!

A couple of years ago, we invited Destin from Smarter Every Day over to Australia to celebrate National Science Week, and while he was here, he wanted to find out more about our adorable native wildlife... and run around and stick his hands in their pouches, as it turns out. As you can see in the episode above (guest-starring our Managing Director Chris!), he pretty quickly found out that a kangaroo pouch doesn't actually look or feel like you might imagine - it's a whole lot more stretchy and fleshy.

But first of all, Destin had to figure out a way to get his hands on a pouch. The first kangaroo he decided to check out turned out to be a male - and although Destin assumed that the fact that human males have nipples meant that male kangaroos would have pouches, that's not actually the case, and he was left feeling around the species' unique testes, which are located just above its penis.

Thankfully, he finally managed to find a female kangaroo, and a kind zookeeper at Taronga Zoo in Sydney lets him stick his hand - and camera - inside. This is the best chance most of us will have to see inside one of these unique biological adaptations, and it's pretty fascinating. It turns out that pouches aren't like pockets at all, they're actually very small openings in the fur that are able to stretch out to reveal a fleshy inside.

And unlike what you've seen in cartoons, joeys in their mum's pouches aren't all cute and fluffy - they crawl in there as hairless, tiny jellybeans, after only around a month of gestation in the womb. You can see that incredible process in the David Attenborough documentary below:



The rest of a joey's nine months of development are spent suckling on a teat in their mother's pouch before they're able to emerge and walk and feed themselves.

But don't take our word for it; check out the episode of Smarter Every Day above to find out more. And no, we don't recommend you try feeling up strange kangaroos at home, because those things sure can kick.




Since most jobs nowadays, requires you to be on site for more than 8 hours plus the stress that you will be getting from the job and your office mates, it is totally stressful day by day. In line with that, people had been dreaming of a job where they could just rest and lay all day in their bed.




Well, NASA is looking for volunteers who wants to be a part of their "Bed Rest Study". The job is as easy as it sounds. The volunteer just needs to rest and lay down on the bed for 70 days straight and NASA will pay you $18, 000.


The individual is allowed to do stuff while they are in bed. They could use Skype, read books and play games on their smart phones.






This study aims to claim the effects of the micro gravity to the human body. The volunteers on this project are supposed to be the people who have a healthy living, not couch potatoes.





“Once they qualify physically and mentally, we do rigorous physical exercises to test muscle strength and aerobic capacity. We want people who have the physical and psychological characteristics of an astronaut. They should be able to do the kind of activities that astronauts do,” Dr. Cromwell said.



So, what are you waiting for? If this is your dream job, then go ahead and see if you are qualified!

Philippines is one of the countries that has a probblem with the electricity especially in the rural places.




An amazing invention was created by siblings Aisa Mijeno, computer engineer and her brother Ralph and and Oscar Bryan Magtibay. They created a special lamp that works with salt solution or a glass of watercombined with two tablespoons of salt.





With that solution, they can have 8 hours of light. The lamp is environment friendly and is safer to use than the usual kerosene-fed lamp used by a lot of Filipinos.




The lamp also runs on sea water so the people who lives near the ocean and seas can gather water from there and pour it to the lamp to have light.








The lamp also has an emergency port where you can charge your smartphones, you just need to plug in the USB Cable.


This project was created to help the less fortunate people who do not have access to electricity. It is a social movement to make life for these people a little less difficult.

Divers found gold in part of a Spanish fleet that was obliterated during a hurricane 300 years ago.

Some of the gold coins treasure-hunters recovered from the wreck of a Spanish cargo ship that sank off the Florida coast in 1715.

Shipwreck divers have announced quite the anniversary present for the flagship of a 1715 Spanish treasure fleet, the Capitana: 52 gold coins, 40 feet of gold chain, and 110 silver coins and buttons all worth over one million dollars.

The find, made over a month ago on June 17, was kept under wraps until now. The Florida family that made the discovery, led by Eric Schmitt, wanted to wait so their announcement would coincide with the 300-year anniversary of the fleet's sinking off the coast of Florida.

The 11 ships were part of Spain's Tierra Firme and New Spain fleets, regular convoys of vessels that transported gold, silver, and other precious resources from Spanish colonies in the New World to Europe.

"The Tierra Firme fleet serviced South and Central America," said Jennifer McKinnon, a maritime archaeologist at East Carolina University, in an interview earlier this year. She was not involved in the current find. The fleet "was vital to the flow of materials back to Spain as well as provisioning the New World with Old World goods." (Read about another shipwreck that was part of the Tierra Firma fleet.)

The ships sank during a hurricane that hit them on July 30 and 31, 1715 as they sailed past Florida on their way back to Spain. (Read about a cursed warship that sank with treasure onboard.)

Schmitt and his family had been working the 1715 vessels under contract with 1715 Fleet-Queens Jewels LLC, a Florida company with exclusive rights to the wrecks, for several years.

Unexpected Haul

Usually Schmitt and his team come up empty-handed. "Typically we excavate empty holes and find beer cans," the shipwreck diver says.

But this time, in 15 feet (4.5 meters) of water about 1,000 feet (305 meters) off a beach in Fort Pierce, Florida, the divers got lucky.

The day started out like any other, Schmitt says. But around 9 or 9:30 in the morning, a gold coin popped out of the sand he was clearing on the seafloor. The dive team started to shift more sand, and ended up recovering the treasure. "It was absolutely unreal," says Schmitt. He called Brent Brisben, co-founder of 1715 Fleet-Queens Jewels to check out their discovery. "I was blown away," Brisben says. "I was literally shaking."

Brisben and his company's contractors have been working the wrecks since 2010. But the current find "is probably the biggest in terms of volume and rarity," he says. The gold coins included an extremely rare specimen called a Tricentennial Royal worth over $500,000.

Regular coins in those days tended to look a bit rough, Brisben says. Their makers were more concerned about the coins' weight and quality of gold or silver. But "they made a certain number of coins perfect, called the Royals, which they would present to the king."

Splitting the Take

Schmitt and his team have continued to work the site that yielded that million-dollar haul. They've found some more silver coins and buttons and several candlesticks since then. But nothing like that initial find.

All of the artifacts are under the jurisdiction of the United States district court of the southern district of Florida under the care of Brisben's company. The state of Florida is entitled to 20 percent of anything Brisben or his contractors find.

Every year, Florida will send representatives to examine anything the teams find, and put in a request for items they'd like to transfer to museums to the Court. If the Court agrees, the company turns the items over, Brisben says.

With the current find, after the state takes its share, Brisben and the Schmitt family will split the rest evenly.

London: Ever wish you could get different fruits from one single tree? A mind blowing video clip provides evidence that it's possible.

In a four-minute National Geographic feature, Syracuse University professor Sam Van Aken which shows his interesting hobby that how using his "chip grafting" method, the tree takes on the task of growing separate fruits by itself, People magazine reported.

The method involves slicing a section of a branch and inserting a bud from a desired fruit tree, taping the wound until it's able to produce on its own.

After a year-long wait, the tree would offer up 40 varieties of stone fruits.

Aken said in the video that project was always an art project for him as he was "really interested in the idea of a hoax in terms of a hoax transforms reality."

The process takes 8 to 9 years in total because each year sees twice the number of branches, with grafting.






It can't be denied that people these days really wanted to look perfect, some even claim that they want perfect eyes, nose lips and everything!

But then it seems that those who undergo plastic surgery aren't thinking of the possible results of what they want.

Meet Ellowe Alviso, a young man who recently became the most talked about person in different social media after his photo went viral!

The photo shows two photos of him, the first photo shows a photo of him before a surgery and the second shows the result of his surgery!








According to Ellowe, he wanted to have a higher nose-bridge and a dimpled chin because he wanted to look perfect whenever he joins talent searches. 


Because of this, he decided to undergo a plastic surgery, he was quite happy with the result, but after two years, his nose started swelling.







According to a Dr. Vicete Gil, his nose was injected with a collagen that was impure that hardened over time. Ellowe already sought for the help of an attorney to file a case against the person who performed the surgery!

Let the whole world know about this story!

Let's play a little game called "what happens when you drop a basketball off the top of a 126.5-metre (415-feet) dam?" The answer's pretty obvious: it's going to fall, right? But what happens if you give it a little backspin before you let go? Well, that's a whole different story, as you can see in the latest episode of Veritasium. And let's just say we definitely were not expecting that to happen.








But what's going on here? As Derek from Veritasium explains, the ball manages to soar such a huge distance through the air thanks to something called the Magnus effect, which affects all rotating balls or cylinders as they fly through the air.

This phenomenon occurs because the air on the front side of a spinning, falling ball is going in the same direction as the ball's spin, which means it gets dragged along with the ball and deflected back. The air on the other side, however, is moving in an opposite direction to the ball's spin, and so the flow separates instead of getting deflected.

Derek explains this much better in the video above with some cool diagrams, but basically that means that the ball pushes the air one way, so the air applies equal force on the ball the other way, sending it flying.

The physics alone is awesome, and it's something that's been used by sportspeople for centuries. But what's even cooler is that researchers are actually investigating whether the Magnus effect could be used to more sustainably power transport. In fact, there are already Magnus effect-powered 'sail boats', that have spinning cylinders receiving force from the air, rather than sails.

Engineers even managed to create a plane with spinning cylinders for wings, and found that they actually created more lift than traditional wings. But they also create more drag, which is why the plane only flew once before it crashed.

The experiments haven't stopped, however. Check out the episode of Veritasium above to find out how scientists and engineers are using the Magnus effect to power a whole new generation of sustainable vehicles. Physics is pretty amazing.






As you're probably well aware, few hours ago, NASA and SETI announced the discovery of Earth's "older, bigger cousin". Called Kepler-425b, it's the first almost-Earth-sized planet that's been found in the habitable zone of a star very similar to our Sun, and the Internet is kind of freaking out about it.

During the briefing, the scientists also announced the discovery of 11 other habitable planet candidates, so what's so special about Kepler-425b? Well, we're glad you asked, because there's quite a lot. For starters, this is our best candidate so far for an 'Earth 2.0', and it could also be the ideal place to look for extraterrestrial life.





Here's everything we know so far:

  • Kepler-425b is orbiting a star called Kepler-425, located 1,400 light-years away in the Cygnus constellation of the Milky Way.

  • The planet is 1.6 times bigger than Earth.

  • Earlier research shows that planets of this size "have a good chance" of being rocky, just like Earth.

  • Kepler-425b is orbiting a G2-type star, like our Sun.

  • The planet is in the habitable zone, which means that it's far enough away from its sun that its water won't evaporate, but close enough so that it won't freeze. 

  • A year on Kepler-425b lasts 385 days, so the planet is only 5 percent further from its star than Earth is from the Sun.

  • The planet is likely to have an atmosphere, lots of clouds, and possibly active volcanoes.

  • Its parent star Kepler-425 is 6 billion years old (1.5 billion years older than our Sun). 

  • Kepler-425 has the same temperature, and is 20 percent brighter, and 10 percent larger in diameter than our Sun.

  • Because it's orbiting a larger star, it's likely to be slightly warmer than Earth.


All of this is pretty damn exciting when you consider the fact that NASA has spent decades searching for a potential new home for humanity, but some of these points are worth highlighting further.

For starters, the fact that Kepler-425b is orbiting a G2-type star is hugely important, because all the other Earth-sized planets that we've found so far are orbiting stars that are cooler and smaller than our Sun.







And then there's the age of its star, which is 1.5 billion years older than our Sun, meaning it's had a lot longer for any potential life to evolve.

"It’s awe-inspiring to consider that this planet has spent 6 billion years in the habitable zone of its star; longer than Earth," Kepler's lead data analyst, John Jenkins, said in a press release. "That’s substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet."

We should step in here and make it clear that we still know very little about Kepler-425b, and have no way of saying for sure whether it's habitable at this point. The planet was discovered the same way that pretty much all exoplanets are - by the Kepler spacecraft monitoring the slight 'dip' in the brightness of its star as it passed in front of it.

This has been followed up with ground-based observations from telescopes in the US, which is why we know so much about the brightness of the planet's host star, and the potential nature of the planet. The results have been submitted for publication in the Astrophysical Journal.

But given the fact that Kepler-425b 1,400 light-years away, we're going to need much stronger telescopes than we have right now to actually see the planet, and get some insight into what's going on there. And fortunately, we're about to get one that will be perfect for the job - the James Webb Telescope.

The successor to the Hubble Space Telescope is scheduled to launch in October 2018, and will be 100 times more powerful than Hubble, making it capable of seeing events that happened in the Universe 13.5 billion years ago.

During the briefing, NASA explained that it plans to use the telescope to perform an atmospheric analysis of Kepler-425b, providing us with some important information on just how habitable it really is. And we're so damn excited to see those results.

In the meantime, I guess we should work on figuring out how we might be able to get to our potential new home. Warp drive, anyone?

While we may not yet know enough to say whether Kepler-425b is habitable or not, we'll leave you with this NASA gif, which perfectly sums up why this news is worth getting a little hyped-up over (hint: the green band signifies the habitable zone).
