In the past, sailors on whaling ships would carve whale teeth into works of art in a process called scrimshaw. These pieces would be brought home to loved ones as mementos of the voyage. Design incubator Studio Swine is attempting to recycle found materials and turn this aged art form into a more sustainable practice. In this short film, travel to remote parts of the ocean, where "the closest people are in a space station," and watch as the process of collecting ocean trash and transforming it into beautiful treasure unfolds.

More than 40 million people worldwide suffer from Alzheimer's disease, and that number is expected to increase drastically in the coming years. But no real progress has been made in the fight against the disease since its classification more than 100 years ago. Scientist Samuel Cohen shares a new breakthrough in Alzheimer's research from his lab as well as a message of hope. "Alzheimer's is a disease," Cohen says, "and we can cure it."

They Might Be Giants animated video 

Mitochondrial diseases are a group of disorders caused by genetic mutations. In this animation, Nature Video finds out how these diseases arise, and how new techniques can stop them being passed on from mother to child.

A new compound, discovered jointly by international pharmaceutical company Servier, headquartered in France, and Vernalis (R&D), a company based in the UK, has been shown by researchers at the Walter and Eliza Hall Institute and Servier to block a protein that is essential for the sustained growth of up to a quarter of all cancers.

Buckle up for a prokaryote and eukaryote comparison before taking a ride into a cell to explore organelle structures and functions! This cell introduction also includes the modern cell theory.

Studying odors from corpses may sound macabre, but it's actually a virtuous vocation. Researchers in this field are helping find missing bodies lost in natural disasters or hidden by murderers. ↓↓More info and references below↓↓

Most 12-year-olds love playing videogames -- Thomas Suarez taught himself how to create them. After developing iPhone apps like "Bustin Jeiber," a whack-a-mole game, he is now using his skills to help other kids become developers. (Filmed at TEDxManhattanBeach.)

It's often said that despite humanity's many conflicts, we all bleed the same blood. It's a nice thought, but not quite accurate. In fact, our blood comes in a few different varieties. Natalie S. Hodge defines the four major blood types and sheds light on why some bloods can mix while others cannot.

2:30 video A video from the Centers for Disease Control and Prevention offering information on the basics of diabetes.

This animation describes insulin resistance, an underlying cause of type 2 diabetes. It explains the roles of glucose and the hormone insulin in our body. Symptoms of diabetes are reviewed and various health complications that type 2 diabetes can lead to if left untreated.

UCSF Diabetes Center researchers explain the basics of both type 1 and type 2 diabetes. Faculty interviewed include Dr. Matthias Hebrok, Dr. Michael German, Dr. Suneil Koliwad, Dr. Stephen Gitelman.

Humans construct boundaries -- around our homes, our neighborhoods, and our nations -- to bring order to a chaotic world. But we rarely consider how these boundaries affect other creatures. In this episode of Think Like A Scientist, we meet conservation photographer Krista Schlyer, who has spent the last seven years documenting the environmental effects of the U.S./Mexico border wall, and biologist Jon Beckmann, who studies how man-made barriers influence the movement of wildlife. Schlyer and Beckmann have seen damaging impacts of the border wall firsthand, but they remain optimistic. Humans probably won't stop constructing walls and fences any time soon, but planning our boundaries with wildlife in mind can help prevent these structures from causing environmental harm.

After coming down with a stomach virus, Luther Glenn became paralyzed. He was diagnosed with Guillain-Barre syndrome, a neurological disorder that can leave people paralyzed for weeks. According to researchers, about 80 percent of people who come down with Guillain-Barre will recover almost fully, while the rest never regain their abilities. Luther is one of those still dealing with the effects of the condition.

In this video Paul Andersen explains how the chloroplast in plants harnesses power from the Sun to form high energy molecules like glucose. The structure of a chloroplast as well as a brief discussion of the light reaction and Calvin cycle are included.

In this video Paul Andersen explains how the mitochondria generates energy for the cell through aerobic respiration. He also explains how research into the organelle has shown its importance in eukaryotic evolution.

8' video on origins of life Paul Andersen describes how life could have formed on our planet through natural processes. The progression from monomers, to polymers, to protocells and finally to cells is described. The Miller-Urey experiment is described in detail as well as characteristics of the latest universal ancestor.
