Ocean-Going Enterprise Sets Sail Next Year

At the time of writing, we know more about the surface of Mars than we do about the delicate complexities of our terrestrial oceans.

However, next year, a daring and innovative new project is seeking to change all that.

Sea Orbiter, referred to be some as the “starship Enterprise for the water” will be a new type of ocean-going research vessel, a moving laboratory that will hopefully allow Human scientists better access to the world's oceans than ever before.

Designed by French architect Jaques Rougerie, Sea Orbiter will allow scientists to study everything from underwater archaeological sites to the migration patterns of marine life. It is also expected to extensively map the ocean floors beneath it and to allow divers to work continually on deeper dives than ever before.

Diving to a depth greater than 50 meters or so can cause decompression illness (DCI) and the only way to traverse this obstacle is via saturation diving, which involves prolonged immersion in hyperbaric pressure chambers. Aboard the Sea Orbiter, however, the entire bottom deck will feature hyperbaric pressure levels so that divers can regularly dive to greater depths, but still enjoy a comfortable standard of living when out of the water.

Theoretically, this means that divers will be able to reach depths of up to 100 metres, day after day, simply by remaining in Sea Orbiter's bottom deck. Also, because the researchers will be diving via a special bay on the underside of the craft, they will be unencumbered by obstacles like bad weather and lack of daylight. In fact, due to this advancement, Sea Orbiter is expected to give researchers unprecedented access to as-yet unknown deep-sea creatures that are only observable at night.



Technology wise, the design appears to have been influenced by the International Space Station (ISS), another innovative project that allowed researchers to reside in their chosen location for long periods of time, something that is always a great boon to scientific research.

Sea Orbiter will also boast mini, remote-operated submarines, as well as a manned submersible capable of reaching depths up to 1,000 metres and an unmanned drone that will be capable of venturing an astonishing 6,000 metres below sea level.

The design of the craft itself is also equally innovative; in fact, the word genius could be applied with little/no hyperbole present. Basically, the craft's tall, conical shape will render it almost impossible to tip, allowing Sea Orbiter to brave even the most violent ocean storm and emerge unscathed.

In fact, Sea Orbiter is far more stable than most other seafaring vessels. The saucer section in the middle of the craft, and the keel directly below it, are both far denser than seawater itself, which would normally be enough for it to sink like a stone, however, the upper portion of the vessel is designed to be exceptionally buoyant and will only be fashioned from the lightest possible materials, meaning that although two thirds of Sea Orbiter will be perpetually submerged, the vessel itself should never actually capsize or sink.

If Sea Orbiter is successful, this design is expected to become the model for a great many future ships.

Solar and wind power will keep Sea Orbiter's engines running, with biofuel on standby for use as needed. This means that Sea Orbiter will be one of the greenest post-industrial vessels ever to sail the oceans of the world and, once again, could become a valuable prototype for the oceangoing vessels of the future.

Heavily influenced by the works of Jules Verne and the pioneering naturalist work of filmmaker and explorer Jaques Cousteau, Jaques Rougerie has designed underwater environments for much of his career, even participating in a World Record setting 71-day stint under water. His work to date has included sub aquatic museums and laboratories and glass bottom research vessels.

He has also created workable designs for underwater habitats such as houses and even entire villages.

Construction of the Sea Orbiter is expected to be completed by 2016, but the project's success still hinges on funding. To date, the French government has provided most of the development money, but the project has also been backed by numerous corporate sponsors and even a public crowd-funding campaign.

If Sea Orbiter's initial mission is successful, Rougerie and his team are planning to build an entire fleet of Sea Orbiters, which could potentially make their collective task the most comprehensive study of the Earth's oceans that has ever been undertaken.

Microsoft Co-Founder Discovers Last Resting Place Of Legendary Japanese Warship

More than 70 years after American forces sank it, the legendary Japanese battleship Musashi has been discovered resting on the seafloor at a depth of 3,280 feet (1KM) below the water’s surface.

The expedition, headed up by Microsoft co-founder Paul Allen, discovered the wreck of the Musashi off the coast of The Philippines.

Allen’s private yacht, the 414-foot-long (125 meters) M/Y Octopus located the wreck in the Sibuyan Sea earlier this month, but the team has declined to offer details regarding the ship’s exact location.

Mr. Allen is known to have been fascinated by the riddle of the lost battleship and has been searching for its final resting place for 8 years.

The Mushashi met its end during the Battle of Leyte Gulf in 1944, and it is thought that over a thousand men, almost half of the ships 2,399-strong crew compliment was killed during the sinking.

The Musashi is a well-known battleship of the era because it was considered to be one of the largest â€"and most technologically advanced- warships ever built at the time. The Musashi was 862 feet long and weighed in the region of 66,225 metric tonnes. However, despite her immense size and reliable eyewitness accounts of her sinking, the precise location of the wreck remained unknown for over 7 decades.

The Musashi’s sister ship, The Yamato, met its end in 1945. The wreck was lost until the 1980’s, when shipwreck hunters discovered her remains 180 miles southwest of Kyushu. The ship was split in two and was found at a depth of 1,120 feet (340 m).

Some underwater footage of the Musashi has been released to the public already. The footage reveals the catapult system once used to launch planes, a 15-ton anchor and the turret from a naval gun.

The ship took her name from the famous Japanese samurai, philosopher and artist Miyamoto Musashi. Musashi was known for his psychological approach to duelling, as well as his unorthodox fighting style. His ‘Book of Five Rings’ (Go Rin No Sho) is considered a classic text on the subject of conflicts and personal discipline.

Musashi made his first kill at just 13 and won his most famous bout by killing the renowned samurai Sasaki Kojiro on the island of Funajima (using a modified oar that he had taken from the boat that carried him to the island). He is the founder of the Niten Ichi-ryu (‘the school of the strategy of two heavens as one’ â€" loose translation) School of swordsmanship. Musashi partook in around sixty duels, many of then to the death. He retired undefeated and died in 1645, probably from cancer.

Returning to the present, a statement on Paul Allen’s website says that, by discovering the legendary battleship, his team hopes to “bring closure to the families of those lost”.

Mr. Allen has further pledged that he and his team plan to work closely with the Japanese government in order to ensure that the wreck of The Musashi is treated "respectfully and in accordance with Japanese traditions."

Security Earpiece For the iPhone

With every passing day, technology is improving and it has made lives of people easier and better in many ways. Some of the latest technologies and gadgets have really been helpful to many people. If you look at the security earpiece then you will understand how advantageous it is for specific people. There are different types of these radio earpieces available and you can also get these for your iPhone. You just have to check whether or not these are suitable and compatible with your handset.

Use Of Security Earpieces

These earpieces are only required when you want to communicate with someone secretly. The security earpiece is fitted into the ears and normally people around you cannot see it. It is small and is connected by a very thin wire. Security personnel mainly use these types of earpieces. But people also use this when they are in a conference and want to communicate or hear something while communicating. You can also find it useful in movie sets, broadcasting of radios etc. Even it will be great for using inside classrooms and not getting caught by teachers!

This is quite small in size the voice transmitted via this cannot be heard outside. Only the person who is wearing it can hear the voice. Thus, you can secretly converse with someone while none will even know about it. In case of audio surveillance, security guards and bodyguards use this earpiece to make sure they can hear each and everything distinctly. When a person is speaking on radio in front of a microphone, he/she has to make sure that even a message comes through the earphone it is not heard outside. So, with the help of the security earpiece it is very much possible.



Connecting To Mobile

Though these earpieces are meant mainly for security purposes, many people find it cool! They use this as a style statement and wear it just for fun. It has become a part of cool accessories which many enthusiasts prefer to use while going out. It is not necessary that you have to be a spy, bodyguard or a secret agent in order to buy or use this. You can simply buy one security earpiece for your iPhone too. it also comes with a separate mouthpiece which you can put on anywhere you feel comfortable.

If you are an owner of an iPhone then you can get the security earpiece for your particular handset. The jack which will be connected to your earphone port of the mobile has to be compatible to each other, normally a 3.5mm Jack. If not then you will not be able to hear or listen to anything. This is very much important. So, it is best to buy the security earphones specially made for each model of iPhone. With the help of this you can talk over phone while driving or even you can hear songs and watch movies.

Some Useful Tips

Since you have to wear these earpieces inside your ears, you have to be much more conscious of it. Make sure that you are not allergic to the material by which earpiece is made up of. If you are then avoid using that material as it can be harmful for you. The earpiece is fitted inside the ear exactly beside your eardrum. While wearing it you have to be careful about whether or not the earpiece is touching your eardrum. If it is not touching then you will not be able to hear anything or you will hear a low voice. When you are done you have to take out that earpiece as well. In this case also you have to be very much careful.

Your ear, mainly eardrum, is very much sensitive. You have to make sure that the security earpiece you are buying for your ears is not made up of some low quality material. It can react badly with your inner ear skin. So, when you are buying one for your iPhone, you have to choose the best one made up of high quality material. These are mainly available in rubber and thus you have to confirm that you are not allergic to it. This is surely a great technology and a cool accessorise for the one who want to use it just for fun for their iPhone.

Can constantly wearing headphones cause baldness?

No, wearing headphones, no matter how often you do it, will not cause hair loss.

This idea is tied in to the same popularly held falsehood that states that constantly wearing a hat can cause hair loss (and even premature baldness). This is, of course, completely untrue.

Here, from Health Central.com, is a particularly good rebuttal to this old wives' tale, it deals with a case study of a man named Mark.

“One of the myths surrounding hair loss is that wearing hats will cause or contribute to premature baldness. Fortunately, for men like Mark, this is not true. There is no scientific research that shows wearing a hat contributes to hair loss. In order for a hat to cause hair loss, it would need to be tight enough to cut off circulation to the hair follicles”.  

However, you may wonder why there is hair in your hat when you take it off (and sometimes rather a lot of it)? Well, according to Health Central,

“One of the reasons many people believe that hats cause hair loss is because of the amount of hair left inside a hat when you take it off. Whenever you see this, you might worry that your hair is quickly falling out. But we lose hair every day, as much as 80 to 100 strands daily. Usually, you will see this as you comb and brush your hair or when you shower. However, your hats may catch some of this hair and as it builds up over time, it may seem as if there is a lot of hair in your hat”

We suspect it also has to do with the psychological reactions to natural conditions like male pattern baldness (or androgenetic alopecia). For example, the person believes that there must be an outside factor causing his hair loss, because it can't be that he is simply going bald for no visible reason. Our hypothetical man tells himself that he's strong, he's virile and he's still a young man â€" he can't possibly be going bald, there must be some other reason for it. Hair loss can be quite traumatic and damaging to a person's self image and baldness is often (wrongly) associated with getting older and less attractive.

In fact, the statistics concerning alopecia are actually quite alarming.

40% of American men experience hair loss by the age of 45, while 65% encounter this problem by age 60 and by age 85, a whopping 80% of American men will have nothing left to comb over. They can't all be wearing headsets.

There are, however, some things that are proven to cause both hair loss and baldness. The following things can cause hair loss:



  • Stress.


  • Hormonal issues like hypo-thyroidism.


  • The side effects of certain medications.


  • Wearing tight hairstyles like pigtails or cornrows.


  • Some chemicals found in various hair products (e.g. permanents or relaxers).


  • Fungal infections.




To date, we don't think anyone has ever gone bald from wearing headphones (although we certainly wouldn't rule out the possibility that many a balding person has blamed it on them!)



If you are worried about losing your hair, a good piece of advice is to look at your grandfather. Why? Well, before we sign off, here is a final piece from Health Central.

“According to an article in ScienceDaily, the gene that is sometimes responsible for male baldness is inherited from the mother because this particular gene is found on the X chromosome. For men whose fathers became bald, this could be good news. It seems you should look to your grandfather, on your mother's side, to find out if you have a higher risk of baldness due to genetics”.

How a Digital Walkie Talkie Works?

The Digital Walkie Talkie is the best way to communicate other than cellular phones on the world market. These devices are still widely used by the military personal, police officers, public event organizers, etc.

You might be quite interested how the digital Walkie Talkie Works? A walkie-talkie is a hand-held portable radio which communicates wirelessly using the radio wave signals on single and shared frequency bands.

Each of the battery-powered units of the device contains an antenna and transmitter/receiver for sending and receiving of the radio waves. It also contains a loudspeaker that doubles up as loud as a microphone when someone talks into it. There is also a "push-to-talk" or PTT button for this purpose.

The loudspeaker/microphone of the device works following the same mechanism as that of the intercom. The microphone and speaker contains almost the same components viz. a magnet, a wire coil, and a plastic or paper cone to pick up and generate the sounds.

You can also use any single device to do both jobs by switching electrical circuit and reversing the current flow. Walkie talkies manufactured by big companies include separate microphones and loudspeakers. Thus, it is based on a very simple mechanism.

How to use the Walkie talkie?

Groups of People who talk on the digital Walkie Talkie don’t need to tune into the same frequency band. Thus the Digital element of the Walkie Talkie. The radios of these walkie talkies are all receiving. Thus, the microphone/loudspeaker units work as a conventional radio.

If you want to talk with others via a walkie talkie, then you need to hold the push-to-talk button on the handset. After that, the radio becomes quiet as the loudspeaker switches over to the microphone.

As you talk into it, your words are converted into the radio waves and are then beamed out on a prearranged channel. Typical frequency of this channel is around 400 MHz. The radio waves are a part of the electromagnetic spectrum, they travel at the speed of sound.

The high-speed sound waves are very easily picked up by the other handsets. The radio waves are converted back into electric currents and are used by the loudspeakers to reproduce the sound of the voice of the person who is talking.

When the talking is finished, the talker says “over” and releases the “push-to-talk” button.

The radio now switches back into listening mode and someone else can talk. After this, the radio switches back into the listening mode.

The most distinct feature of the digital Walkie Talkie that makes it quite different from the normal radio is that it is a 2 way radio that is you can talk as well listen with the help of this device.

What are the benefits of using these devices?

The digital Walkie Talkie is a simple, robust and easy to use device for indoor as well outdoors. These devices are also very much suitable for the children as these are very light and easy to carry and handle.

The kids can keep in constant touch with their parents with the help of these devices. These are very much suitable for the business application purposes.

What are the major specifications?



A Digital Walkie Talkie is very convenient and weighs 100-200 grams and can work over a 5 to 10 square kilometer or 2-4 square miles. These electronic devices also have a very long battery-life of almost 20 hours.

The Walkie-talkies have multiple channels. So you can easily switch from one to the other easily. Some walkie talkies also have baby monitor intercoms.

What are the various parts of this device?

Variois parts of the digital Walkie Talkie include antenna, LCD displays, select buttons, monitor, menu buttons, loudspeaker, PTT button, volume control, on/off switch, microphone, LED indicators, etc.

The radio waves are sent and received by the antenna. The LCD display shows the channel number, battery life, etc., baby monitors are sometimes fitted within the device, the menu buttons are used to change the settings and functions of the device.

The LED indicate light glows showing that the channels are all busy.

The digital Walkie Talkie is offered at very reasonable and affordable prices by the best online shops. These are also very durable and flexible when in use. Therefore, it is a very useful telecommunication device for the people of all ages and backgrounds.

In the Early Years: Technology improved for Oneonta police in 1935

Criminals in 1935 would not find Oneonta to be a “pushover” town when it came to law enforcement.

“The Oneonta Police department is preparing to meet the modern gangster on even ground,” The Oneonta Star reported on Monday, Jan. 21, that year. “In the near future, Chief Frank N. Horton announced yesterday, the department will be equipped with a sub-machine gun and a two-way radio-telephone service.”

 These were state-of-the-art technology upgrades for the time and Oneonta appeared to be proud of them, approved by Common Council in the 1935 budget and said to “bring Oneonta’s Police department on a par with other cities in the state, and will materially aid in preventing crime.”


Officers were ready to be trained to use the machine gun, which could fire a 50-shot drum in three seconds, a rate of 800 shots per minute. It weighed nine pounds loaded, so the weapon could be used with one hand like an ordinary revolver for single-shot fire.

To the best of my knowledge, there was never a time or crime in that era that required such firepower in Oneonta. The other new crime fighting tool, the two-way radio, was handy and useful.

By April, the radio equipment had arrived and been installed at police headquarters (then found at the Oneonta Municipal Building, today’s 242 Main St.), as well as the two “prowl” cars used on the streets. Tests were made all over the city and outside the limits, and all transmissions were strong and clear.

Prior to this new technology, The Star reported that officers had to watch for a red light at the top of the municipal building, indicating an emergency was in progress. Instead of awaiting the arrival of a prowl car to pick up the emergency information at headquarters and go, officers could now be dispatched and head to the scene immediately.

Another advance in police work in Oneonta came in March 1935. The department sought supplies used for fingerprinting individuals who wanted to have their fingerprints on file for personal identification purposes.

“Several months ago the department of Justice advocated national fingerprinting,” said M.L. Thomas, a fingerprint expert in the department. “Many Oneontans responded and their records are now on file at Washington, D.C.” It appears the program was tried earlier and was now becoming a permanent part of Oneonta’s police work.

Outreach to young people was part of crime prevention in 1935, just as it is today. On Thursday, Feb. 14, Police Attorney Joseph P. Molinari was a guest speaker at Oneonta High School.

“Crime does not pay and the life of a gangster is short,” Molinari told the students, himself a 1919 graduate of OHS. He pointed out the short careers of John Dillinger, “Pretty Boy” Floyd and “Baby Face” Nelson, stating that “these criminals could never have enjoyed life on their ill-gotten gains, as their luck could not go on forever. In the end they were killed and society was avenged.”

Molinari was in his early career at the time in Oneonta. It was only about a month later, Thursday, March 7, when Molinari announced he was seeking the post of Otsego County district attorney, a job he was elected to. In 1943, Molinari became Otsego County judge, and in 1951 New York’s Sixth Judicial District Supreme Court justice.

While police work was becoming more high-tech in 1935, the routine tasks still needed to be done, which many area residents of 2015 might identify with.

“Stop does not mean slow,” Chief Horton declared on March 25 while announcing that motorists must observe the various stop signs about the city. Police opened a campaign that day to compel motorists to observe the signs and had issued four summonses to drivers failing to stop. Those drivers were set to appear before Judge Frank C. Huntington in city court.

Interestingly, the signs were triangular in shape and made of iron, but the article in The Star didn’t tell what the color was at the time.

On Monday: The region went in front of the cameras for production of “Susquehanna Stories.”

Mark Simonson is Historian of Oneonta City, Twice a week he writes for the thedailystar.com, including this article. What he outlines in this article is more about Two way radios, but also early 20th century crime prevention techniques.

How Do Ear Defenders Work?

Are you working in a very noisy environment? Do you find yourself under very loud working conditions? Then, you definitely need the best Ear Defender in order to keep your hearing system unaffected by the surrounding noise.

People can get short of hearing and even deafness if they work in noisy work conditions for long and even short terms. Thus, using a hearing protection aid is a must for them. If you are a professional music player, you need to fit electronic devices like Apple iPod or MP3 style players with your ears. The noises from these headphones can damage your ears and your hearing power can be reduced.

Thus, you need to use the noise reducing headphones for these purposes. These types of devices are also known as the ear defenders, How Do Ear Defenders Work? This can be a first question in your mind.

How the Ear Defenders Work?

The noise reducing or noise cancelling headphone ear defenders work in two major ways. The first one is that these are usually designed to perfectly fit over the years with a thickly padded outer layer.

This layer acts as a physical barrier and blocks the high noise frequencies very effectively of the surrounding environment. These types of headphones are a bit bulky but these are highly effective ear defenders. These headphones are also commonly used in the noisy construction industries and perform very well.

This device leaves the low frequency noises and these get away through the physical barrier portion of the noise reducing headphone. There is a very small microphone inside the headphone that pocks up the unwanted noise or sound.

The highly advanced electronic circuits inside the headphones turn the sound wave into an opposite sound wave and play it back along with the music you are currently listening. The 2 sound waves of the external noise function to eliminate one another.

Because of these two technologies the passive high frequency barrier and the active lower frequency noise cancelling technology and the noise reducing headphones are the ideal for using in noisy environments of any type like offices, train plane journeys, etc. These devices cut off all the unwanted background noises which may disturb you.

Even if you want to listen to music peacefully you can only listen to the music by cutting of the unwanted surrounding noises with the help of the noise cutting headphones. These devices also work effectively while you are talking with someone on your mobile phone and the call is disrupted by unwanted surrounding noises.

How to protect your years?

The sounds are all turned into electrical signals that finally reach your brains. The tiny hairs of your cochlea pick up the sound vibrations. These hairs can get damaged if the sound vibrations are too high. The inner ear damages cannot be reversed.

Noise in the factories is one of the biggest sources of severe hearing losses. Thus, the workers in the factories, who have to work for long hours face serious hearing problems. They must use the most technically advanced ear defender for protection during the working hours.
