This GIF Shows The Inside of the Human Body, From Head to Toe (GIF and Video)

Back in the early 90s, scientists from the U.S. National Library of Medicine came up with a bold idea: imaging the entire human body, from top to bottom, in cross-sectional segments only a millimeter thick. They called the endeavor The Visible Human Project. Two cadavers, one male and one female, were encased in gelatin and then frozen into ice blocks, at frigid temperature of -160 degrees Fahrenheit (-71 degrees Celsius). Then, a sophisticated cryogenic microtome (basically a very finely-tuned deli slicer in a

Chinese Boy Receives First 3-D Printed Vertebra Implant (Video)

Doctors at Beijing’s Peking University have made a truly monumental step in the field of orthopedic surgery: implanting the first ever 3-D printed vertebra into a 12-year old boy. After he suffered a neck injury while playing soccer, it was discovered that the boy had a malignant tumor on his spinal chord. Following an examination of the tumor, the boy’s doctors decided that their only choice was to remove his entire second vertebra. But rather than replacing it with a traditional orthopedic implant, the

Why Ultra-Pure Water Is Actually Bad for Your Health (Video)

We tend to imagine that purity is the ultimate indicator of the quality of water. So why is 100%, ultra-pure water not good for us? Well the simple answer is that water (H20) purely comprised of hydrogen and oxygen doesn’t provide our body with the natural electrolytes and salts we need to survive. There is no such thing as truly pure water in the natural world. Even water in the purest springs and lakes contains small amounts of dissolved minerals such as sodium, chloride,

Using Abstract Shapes to Capture the Motion of Legendary Olympians (Video)

Felix Deimann, a young motion artist from Dortmund, Germany, has always been fascinated with the dynamics of motion. So for his final college thesis project, he decided to use digital graphics and abstract shapes to capture some of the most iconic athletes from the history of the Olympic Games. His subjects: Nadia Comăneci, the first gymnast to ever earn a perfect 10, Michael Phelps, the most decorated Olympian ever, the legendary U.S. basketball Dream Team that dominated the ’92 games in Barcelona, and

Did You Know… Your Skin Can Smell. And the Scent of Candlewood Makes It Heal Itself

Olfactory receptors are the cells which give us our sense of smell. The average human has five to six million of these olfactory receptors in their nose. Though there are other creatures with more powerful noses (dogs have up to 220 million olfactory receptors), the human sense of smell is actually one of the more acute in the animal kingdom. But olfactory receptors aren’t just in the nose. In recent years, scientists have been finding them in all kinds of strange

Korean Scientists Just Built A Two-Legged Robot That Can Outrun Usain Bolt (Video)

They call it the “Raptor”, and its design is largely based on the anatomy and dynamic movement of the velociraptor which roamed the Earth nearly 100 million years ago. At 46 km/h (26.8 mph), it is the fastest two-footed robot ever, faster even than the world’s fastest man Usian Bolt, whose top speed has been clocked at 43.92 km/h. The robot, designed by scientists at the Korea Advanced Institute of Science and Technology (KAIST), uses a number of elements from nature,

Doctors Are About to Start “Deep-Freezing” Humans For Suspended Animation Trials

You’ve probably seen it in sci-fi books or films before: some doctor or mad scientist will deep-freeze a patient only to bring them back to life later on. Well, suspended animation, as the process is called, is no longer a figment of the science fiction imagination. This month at UPMC Presbyterian Hospital in Pittsburgh, Pennsylvania, 10 people will be put into suspended animation. But rather than using the process for intergalactic travel or some other futuristic application, the doctors will use

New Discovery: HIV Can “Cut and Paste” In Our Genome, Allowing Us To Use It to Repair Genetic Conditions

Researchers in the Department of Biomedicine at Aarhus University in Denmark just did something truly amazing: they altered particles of the HIV virus to simultaneously “cut and paste” within our genome. Here’s Jacob Giehm Mikkelsen, associate genetics professor at Aarhus: “Now we can simultaneously cut out the part of the genome that is broken in sick cells, and patch the gap that arises in the genetic information which we have removed from the genome. The new aspect here is that we can

A Team of MIT Students Is Developing A Wristband That Could Totally Replace Air Conditioning

Sam Shames is an MIT student who had spent a lot of time dealing with a fairly common problem: he tends to run hot while his mom tends to run cold. Sam realized that there had to be a better way to accommodate them both. He set about doing research on how our bodies regulate temperature. In one particular paper, he found some key information: the study talked about how locally heating or cooling small areas on our body can have major

Visualizing Size and Scale in the Brain (Infographic Video)

The average human brain weighs only about 3 pounds, but contains upwards of 80 billion brain cells, or neurons. Nearly every detail about who we are and how we behave is locked in the connections between these neurons. Check out this awesome infographic video from Nicolás Borie Williams which helps you visualize things on the same tiny scale that our brains operate on.
