5 Best Accidental Inventions

Author: Heather Brown

There are some scientists who were born to naturally experiment on new things with its core goal to invent, while there are a few who become surprising targets of accidental experiments leading to life changing inventions and discoveries that definitely earn them accolades. As what they say, it is better be lucky than good. Below are 5 of the notable and famous accidental innovations in the history of mankind.

•  Pacemaker

Pacemaker

A medical device that utilizes electrical impulses to regulate heart’s beat, can you imagine that being an accidental invention? Be thankful to Wilson Greatbatch, an assistant professor who accidentally pulled a wrong resistor from the toolbox while experimenting on recording the heartbeats. Instead of pulling 10,000-ohm resistor, he pulled the 1-megaohm variety that caused the circuit to function differently. Since then, his accidental invention has saved the lives of many.

•  Microwave Oven

In 1945, an engineer at Raytheon, Percy Lebaron Spencer was working with devices like magnetrons to radiate microwave signals, which are used during the early radar system. When a fine day came that he noticed a melted candy in his pocket, he decided to build a container box with microwaves being emitted by magnetron, which also made the candy to melt. He did not know that his accidental observation has produced the microwave oven that the contemporary world has been using.

•  X-Rays

X-Rays

Didn’t you know that the machine that all medical establishments use today is accidentally invented as well? It was the accidental innovation of German physicist Wilhelm Roentgen that created X-rays while he was fooling around with radiation cathode-producing rays experiment in 1895. While he was switching on the cathode rays, he noticed that the fluorescent light in his lab was glowing. He decided to cover the screen but the glow was still insisting until he accidentally placed his hand between the screen and the tube and noticed the silhouette of his bones. And so, X-rays were accidentally innovated.

•  Radioactivity

Because of the influence of the discovery of X-rays, Henri Bacquerel also made an accidental experiment that further led to the discovery of radioactivity by the couple scientist Pierre and Marie Curie. It happened when Henri wrapped all his equipment with cloth during the winter season and left them in a drawer. When he came back, he saw a burned image on the photographic plate caused by the contact of uranium crystal. And this accidental experiment has led to the discovery of now the power of nuclear weaponry.

•  Penicillin

Alexander Fleming accidentally invented Penicillin through leaving an unclean petri dish. When he came back from a vacation, the petri dish, which had Staph bacteria originally in it, had produced mold that actually killed all the bacteria left in that dish. He named the mold Penicillin notatum, and led to the discovery of Penicillin, an antibacterial medicine used worldwide these days.

3D Printing: What this Technology Has Done To the Past and the Future of the 3D Industry

3D printing is brought to life by fusing several layers of materials which are made out of durable metals and plastics based on a particular template. This basis was made possible by the use of a CAD (3D computer aided design) software. Each of these layers is approximately 0.1 mm thick and consists mostly of sheet, powder and liquid materials.

With this kind of technology, along with a 3D printer, anyone can come up with a design and 3D print templates of anything. To give the readers a better picture of what 3D can achieve, here are five of its most popular models:

1.  Camera Lens

Hand-made camera lenses are difficult to design because of the complexity of its design. However, with the emergence of 3D printing, anyone could make their own lenses. Aren’t unique and creative designs more achievable with this?

2.  Fully-functional Gun

In the previous years, 3D-made firearms are easy to break with just a few rounds of firing. Fortunately, the non-profit organization Defense Distributed came up with the downloadable template which users can use anytime. With this important design, gun fanatics can print their own firearms with just a 3D printer in the house.

3.  Figurines From Drawings

Most mothers have wished to acquire an effective method of turning their little ones’ drawings into more profound materials for easy keeping. But turning drawing into sculpture? Isn’t this idea impossible? No. With the use of a 3D printer, any child’s colorful drawing can be turned into a masterpiece- a thing that can last a lifetime.

4.  Medical Models

If technology is to be taken in as a subject, science will always be a part of the conversation. With the emergence of 3D printing, medical professionals will have a better and cheaper alternative to cadavers—their typical tool for learning human anatomy better. 3D medical models have a touch of realism to it because the models can be made to have the exact dimensions of the actual template. Because 3D printing is made accurate, all surgeons nowadays can plan on a complex surgery case with the use of a realistic 3D medical model. This way, the real patients will not go through the real knife for nothing.

5.  iPhone Cases and Card Holders

Unique 3D iPhone cases do not only hold an iPhone, it can also accommodate cards. Today, there is a popular Mondriaan Case which is brought to life through the 3D printer. Its designer has made it in several colors so that buyers can have a wide array of options.

4 Strange Body Functions

Author: Heather Brown

Our body is made up of different systems and is composed of different organs to perform functions necessary for optimum health. Body functions are important that they are being taken care of so that you live longer and happy. With the usual body functions, an alteration on them would mean that you either are sick or you need something to trigger to compensate to the needs of the body. Speaking of usual and normal body functions, did you know that there are strange ones?

How do you tag a body function strange or weird? If you are not a medical person, you would even consider the whole process or functions of the body weird. To give you a hint, here are some of the strange functions of the body.

1.  Tongue

Did you know that a human tongue has something in common with an elephant trunk or with the tentacles of an octopus? Yes, these three are distinctive structure of “muscular hydrostat”, which is a group of muscles that can work even without the help of bones. Your tongue does not contain bones but they can be very flexible and strong. So imagine if your tongue is the same size with an elephant’s trunk, there is no doubt that it can uproot trees as well.

2.  Hair

People really love pitching facts about hair. Some would even say that your hair can still grow even after death. That is definitely a fun myth. After death, your nails and hair never continue growing; instead, the skin retreats during dehydration which leads to the creepy illusion of horrid growth. In reality, hair has a strange combination of living and the dead. We are talking about cells here.

3.  Liver

Liver is considered to be the largest vital organ of the body. It performs major functions and involves lots of systems. Did you know that your liver is like the maintenance of your body? Among the major organs, your liver is the most resilient. Though it does not appear cute and nice, it is the organ that makes you lucky. It can regenerate on its own.

4. Walking Proteins

Of the microscopic matters in your cellular biology, the strangest is probably the kinesin protein. It is considered a “motor” protein responsible to deliver significant molecules to their respective destinations. What makes it weird? It walks with its feet – considered to be the base of its micro-pathway. Literally, it resembles assisting humans in a pathway. It is like in a place where the mode of transportation is just walking.

Steve Irwin

Author: Admin

The field of zoology has many notable names with some of them dating back several hundred years. However, there are also more modern zoologists that have managed to make contributions to the field that the world will not soon forget. One zoologist that has managed to make a difference and raise awareness is a Steve Irwin. While he may be more known as a TV personality who wrestles crocodiles on TV and featuring different animals, Steve Irwin was also a zoologist, a naturalist, and a conservationist. He was more than just a guy in khakis playing with animals on TV so get to know more about Steve Irwin and his work. He left the world too soon by means of a freak accident but he will be remembered forever.


His early life

Steve Irwin was born in Essendon in Melbourne on February 22, 1962 and shared the same birth date with his mother. His parents were Lyn and Bob Irwin and they moved to Queensland in 1970 when he was still a child. He went to school at Landsborough State School and for high school he attended Caloundra State High School. It really is not surprising why he became interested in animals because according to Irwin his father was a wildlife expert that had a huge interest in herpetology while his mother Lyn worked as a wildlife rehabilitator. In fact, when they moved to Queensland his parents started a modest-sized park known as the Queensland Reptile ad Fauna Park. Young Steve Irwin grew up in the company of not just crocodiles but other types of reptiles as well.

Steve Irwin was involved in the running of the park and was involved in several aspects of how it was run. He not only took part in the daily feeding of their animals but he also made sure they remained in good health and maintained the park facilities. While most young boys got bicycles or other toys for their birthdays, he was given a 4m long scrub python and by the time he turned 9, he was already handling crocs like a pro and wrestled his first crocodile under the watchful eye of his father. As he grew older, he did volunteer work for the East Coast Crocodile Management program in Queensland where he helped catch over 100 crocs. Some of the crocs where transferred to his family’s farm while others were relocated. He would spend months at a time looking for wayward crocs before they were hunted so he could relocate them to safer areas and all this he did with the help of his dog, Sui.

His personal life

It was in the year 1991 when Irwin met a naturalist from Oregon named Terrie Raines and she was to become his wife. It started out innocently enough with Raines visiting Australia to check out wildlife rehabilitation facilities and decided to pay a visit to Irwin’s zoo. According to them, it was love at first site and after a four month engagement they got married in Eugene, Oregon.

They have two kids; the eldest is a girl named Bindi Sue Irwin and little boy named Robert Clarence Irwin. The girl was named for Irwin’s favorite animals and his dog while the little boy was named after Irwin’s dad. It has been said that if Irwin was enthusiastic about his animals, he was doubly in love with his family and kids. The Irwin’s were a happy family and made a great couple but they did not wear rings since they believed the rings could pose a danger to themselves and the animals they handled.

His career

Instead of going on a honeymoon as average couples are wont to do, the Irwin’s decided to trap crocodiles together and the footage they took during their honeymoon became the very first episode of Irwin’s hit show the Crocodile Hunter. The show debuted on Australian TV in 1996 and slowly made its way to the US, the UK, and 130 other countries and was enjoyed by more than 500 million people.

As a host, Irwin was personable and exuberant and his broad Aussie accent just made him that much more appealing. Pretty soon, the Australian TV host not only had a signature catchphrase (crikey!) but also had a signature look that always consisted of a shirt and khaki shorts. Sir David Attenborough heaped praise on Irwin saying that he was a natural born communicator and taught people of all ages just how wonderful and exciting Mother Nature was. After the last episode of The Crocodile Hunter aired, Irwin went on to star in other Animal Planet shows and documentaries some of which are: Croc Files, New Breed of Vets, and The Crocodile Hunter Diaries.

Honors

Someone who loved the wild and animals and worked hard to promote the environment deserves awards and Steve Irwin got a lot of them. In fact, he even has a turtle named after him while he discovered it during a fishing trip. He called it the Irwin’s turtle or Elseya Irwini. An air-breathing type of snail that was found in Australia was also named after him and it is known as the Crikey Steveirwini. He was granted awards in Australia and other parts of the world for his conservation work. He was even nominated for the Australian of the Year Ward at one point.

His death

Steve Irwin did not fear animals but he had a healthy respect for hem and what they were capable of doing. This is why what happened in September 4, 1996 so shocking. He was snorkeling in Batt reef when he was hit in the chest by a stingray which brought on his death. It is believed that his is the first and only ever death by stingray that was captured on film. All copies of the film were destroyed at the request of his family.

He is survived by his family and his legacy to protect nature and take care of animals is something that his kids and wife are doing their best to continue.

5 Strangest Fossils Ever Found

Author: Heather Brown

Scientists love to categorize things, especially those who specialize in fossils. They enjoy the tedious process of classifying fossils according to their designated species. Paleontologists with amateur fossil hunters are continuously discovering new reserves – each of them is named and classified. However, paleontologists have never officially assigned one classification to “strange” fossils.

What makes a fossil bizarre? For some, it would depend on where and how it was discovered and the story it makes about the prehistoric past. While for others, strange fossils are those that look unimaginable and unfamiliar. Well, can you consider this picture strange?

For that, here are the 5 strangest fossils ever found. Can you imagine that they once roamed the earth?

1.  Gigantic Ant Fossil

There were four paleontologists who discovered this strange fossil, which included two from the Simon Fraser University. The gigantic ant fossil has showed how the events of global warming affected life distribution around 50 million years that passed.

The newly found gigantic ant fossil was named Titanomyrma lubei. It was believed that this winged giant ant lived in the Eocene Epoch and is already about 50 million years of age. Its body sized up to 5 centimeters long, which can be compared to a hummingbird.

2.  The Devil Frog, Beelzebufo

Discovered in Madagascar, the 70 million-year old giant frog fossil sized like a beach ball. The fossil was called by scientists, Beelzebufo or the devil frog. The enormous frog fossil weighed about 4.5 kilograms and with a height of 41 centimeters.

3.  A Nest of 15 Baby Dinosaurs

In 2011, paleontologist from University of Rhode Island, David Fastovsky discovered in Mongolia a nest of fossil remains from 15 juvenile baby dinosaurs, which were then classified as Protoceratops andrewsi dinosaur species. This is the first nest of the dinosaur specie ever found.

4.  Biggest Prehistoric Megalodon Shark Jaw

The Megalodon shark was considered to be the largest predator to have lived on earth. The jaw of the shark took 20 years to be reconstructed and it measured almost 9 feet tall and 11 feet across – the biggest ever assembled.

5.  Spider Attack Fossil (100 million years old)

This is the first and only spider attack fossil ever discovered and caught in amber. This spider existed in the Hukawng Valley in Myanmar during the Early Cretaceous period, around 97 to 110 million years ago – almost definitely with dinosaurs roving just nearby. This strange discovery was preserved with remarkable detail as these fossils are considered to be rare.
