WTF Is On Its Way To Earth As Unidentified Space Debris

WTF (to be precise WT1190F) is an appropriate name for the unidentified object that is currently hurtling towards our planet at alarming speed. No, my friends, I haven’t taken up a job writing for the Weekly World News. What sounds like science fiction (or at least an episode of Futurama) is actually science fact.

The object is set to crash into us in less than a month. Despite its relatively close proximity to our atmosphere, nobody is quite sure just what WTF actually is. All anyone knows is its size (roughly two metres in length) and the fact that it is hollow, strongly hinting at the possibility that the object is man made.

Experts are suggesting various possibilities as to the identity of the mysterious object, the most tantalising being that WTF is actually a piece of leftover technology from the moon missions (possibly even the fabled Saturn V that took Neil Armstrong and co to the moon). Of course, it could just be here to talk to the whales (Star Trek joke, in case anyone reading this is scratching their heads).

The problem of space junk is becoming more serious by the day. In addition to approximately 3,700 satellites currently orbiting the earth (of which around 2,600 are totally inactive, effectively making them space junk), there are literally tens of thousands of objects larger than a tennis ball floating above our heads at any given time. In addition to that, there are an estimated hundred million objects in the 1mm or less category. Put simply, space is a mess.

In 1997, there were 2,271 man-made satellites orbiting the earth, a number that has increased by around 1,500 since then. Instead of slowing down, however, the recent rise in private satellite launches will likely see these figures (if you’ll pardon the pun) skyrocketing over the next decade or so.

In fact, last year alone, the International Space Station (ISS) had to move its position three times in order to avoid collision with objects large enough to cause serious damage. These collisions were potentially fatal to the astronauts aboard the space station. The ISS actually spends an alarming amount of time ducking and dodging flying chunks of space junk, some of which is detected too late for the ISS to manoeuvre away from it, causing the astronauts to simply shelter-in-space and hope for the best. In 2007, a chunk of debris actually damaged the space shuttle Endeavour.

Despite laws that state that most satellites must be launched to an altitude that will encourage them to fall to earth and burn up within 25 years of their original launch, launching anything into space is a messy business indeed. This has led to fears that the population of space junk in earth’s higher obits could actually become self-sustaining, i.e. new junk could be created in the frequent collisions between existing junk. This is often referred to as The Kessler Syndrome after Nasa scientist Don Kessler, who first warned us about this process as far back as 1978.

The Kessler Syndrome is a very real concern. In 2009, for example, two small satellites collided over Siberia, creating something like 2000 new junk items, many of which are still in orbit today and posing a very real threat to existing satellites. Keep in mind that these items can travel at speeds exceeding 17,000 mph; at that sort of speed, even a grain of sand could kill.

The good news is that WTF is expected to burn up harmlessly in our atmosphere, meaning that, although we’ll probably never know its true identity, at least it won’t harm anybody. If it fails to burn away completely, WTF is expected to land on the Indian Ocean, somewhere off the coast of Sri Lanka around the 13^th of November. So, unless you have a fishing holiday planned in the region, you ought to be safe.

Audiology Affiliates Explains the Process of Selecting the Right Hearing Aid Model

When someone start talking about hearing aids and hearing loss, most people run a mile, but as this article shows choosing the right hearing aid can make a difference, using the 4 factors framework listed below. 

Modern hearing aid technology is capable of treating just about any type and degree of hearing loss. This has resulted in a proliferation of hearing aid models that can feel overwhelming to the consumer. Navigating through the maze of hearing aid manufacturers, styles, and advanced functionality can seem like an insurmountable task.

That’s why Audiology Affiliates has release a helpful guide titled How to Pick the Right Hearing Aid Model. The guide describes how all hearing aids work, what makes the various models different, and how to choose among the many options by considering four factors.

The four factors to consider are style, ease-of-use, functionality, and price. These four factors cover cosmetic preference, issues with handling and care, specific functionality based on the type of hearing loss, and financial concerns. With all the hearing aid models available, there is likely a model that will meet all of the criteria for each individual patient.

After reviewing the four factors, the patient is ready to work with a hearing specialist to find the ideal model. The hearing specialist serves three very important roles. One, they can test the patient’s hearing to determine the type and degree of hearing loss. Two, they can guide the patient toward the optimal hearing aid model. And three, once the hearing aid is selected, they can program the hearing aid to amplify sound according to the exact characteristics of the patient’s hearing loss.

Cancer affects millions of lives, possibly even more. Everybody knows somebody that has been forever hurt, either physically or emotionally, by this vicious, unforgiving ailment. Most of us know somebody who has lost their life to the disease.

Despite this, cancer survival rates are higher than ever before. In recent years, cancer treatment has improved rapidly, but a complete cure has always appeared to be just beyond reach, a tantalising Holy Grail of medical science. This month, however, an announcement was made that could have the potential to end all that.

The good news is that human trials could begin in as little as four years’ time. If those trials prove to be successful, then science will have made a major stride towards eradicating the disease completely.

A joint Dutch/Canadian team stumbled across this miraculous discovery whilst searching for ways to treat malaria in pregnant women.

According to the team, the carbohydrate that malaria attacks in the placenta is exactly the same as a carbohydrate present in cancer cells.

As Metro.co.uk reports, Ali Salanti from the University of Copenhagen said, “for decades, scientists have been searching for similarities between the growth of a placenta and a tumor (…) The placenta is an organ, which within a few months grows from only few cells into an organ weighing approx. two pounds, and it provides the embryo with oxygen and nourishment in a relatively foreign environment. (…) In a manner of speaking, tumors do much the same, they grow aggressively in a relatively foreign environment.”

Intrigued by this idea, the team tailored a special malaria protein to include a toxin designed to target cancerous cells. The cancer cells absorb the protein and are then in turn killed by the malaria virus. Theoretically, this idea is sound and experiments on mice with cancer have already begun.

It’s definitely early days yet, but the team are hopeful that this innovative new treatment could provide scientists with a valuable weapon in the fight against cancer. If the trials are successful, the potential benefits are simply staggering to consider. It just goes to show that no dream is too big to accomplish, provided we never stop believing that it’s possible. Imagine a world without cancer and perhaps, in time, we won’t have to.

What Does The Term 2 Way Radio Really Mean?

Basically, the name two-way radio means that the radio in question can both transmit and receive signals. The two-way part of the name refers to the sending and receiving of said messages.

Some radios, such as the AM or FM radio you might listen to in your car, can only receive incoming signals, whilst other radios can only transmit signals. A two-way radio, however, can both intercept incoming messages and relay outgoing messages, because of this; two-way radios are a type of transceiver.

At its most basic, a two-way radio is a device that receives radio waves through the air and transmits a return signal.

How it does this is actually rather ingenious. Let’s say a user receives a message on her radio. The antenna on the top of the radio houses a group of electrons, these electrons will respond to messages received on specific channels (different groups of electrons respond to different channels). The electrons will then translate the radio waves into electrical impulses, which are then fed to a small processor. The processor, in turn, converts the electrical impulses into a signal, which the radio’s speakers can then play aloud.

The process is reversed if our hypothetical user is replying to her message, in this instance, the vibrations that constitute her voice will rattle a small membrane inside the microphone. These vibrations are fed into the processor, which converts them into an electrical signal. The electrical signal is pushed out to the electrons in the antenna and the signal is broadcast to our other user.

So you see, the process is clearly working on a two-way basis, hence the name. Two radios, when set to the same channel, should never have any problem connecting with one another (even if they are manufactured by different brands). The communication is pretty much instant, which is a big reason why radios play such an integral part in many areas of our lives, such as travel, security, commerce, public safety and trade.

It is important to note, however, that a radio set to receive VHF (Very High Frequency) signals will be unable to communicate with a radio set to UHF (Ultra High Frequency) mode. There is virtually nothing at all that can be done about this.

Of course, the other name used for handheld transceivers in walkie-talkie, but we reckon that one’s pretty self-explanatory…

Important things about Purchasing a Looking for a new communication method for your restaurant? walkie talkies could be the answer

Running a restaurant is hard. Personnel in different areas need to communicate well in order to provide the best dining experience for customers. The conventional way people restaurant staff communicate is by shouting or talking loudly at each other. While this can be an effective way to communicate – this method has worked for years – it turns a restaurant into a noisy and chaotic place. Many customers are actually looking to dine in peace. So having all those noises, even if they are meant to provide better service, can actually turn off customers. Restaurant staff can communicate without disturbing the dining experience of customers with the use of walkie-talkies. two way radios for restaurants provide plenty of benefits . The most important ones are discussed below.

A good Investment

Many restaurant owners are having second thoughts about buying walkie-talkies because of the additional investment that it entails. The hesitation is understandable since running a restaurant is expensive as it is without a communication system. But if you are a restaurant owner, you can look at buying a walkie-talkie as a good investment. Having a walkie-talkie for your restaurant can help you serve your customers more efficiently. It can improve customer turnaround time and it can help provide a better dining experience for your patrons. All of these improvement can translate to more profits for your restaurant. So if you are looking for a way to improve your operations and make more money in the process then improving communication system by getting walkie-talkies is a good idea.

Improve Communication

In any organization, good communication is important. A bad communication channel can ruin the good relationship among the staff and between a manager and the people around him. If you own a restaurant, then you probably already know that it is a pressure-packed environment. It doesn’t take much for someone to crack under this kind of pressure. A good communication tool such as walkie-talkie can help ease the pressure. It can avoid miscommunication. If you are a manager, for example, and you noticed that tables are not set yet. Instead of shouting across the room and creating an angry atmosphere in your restaurant, you can simply relay your instruction on the walkie-talkie.

Choosing the right Walkie-Talkie

Of course, not all restaurant walkie-talkies are the same. Some are better than others. Not all walkie-talkies are created equal. When choosing a walkie-talkie, the first thing that you need to consider is performance. The system should be able to provide clear audio that has the ability to break through the noise that is usually present in a restaurant. A bad walkie-talkie can affect your business as adversely as the absence of a walkie-talkie system. Can imagine a restaurant staff trying to decipher the message being relayed by his manager over a walkie-talkie that is sending choppy signal? This kind of scenario can turn into a tragedy very quickly. The next thing that you should look for is comfort. The walkie-talkie should allow freedom of movement for the staff to be able to perform their job well.
