Laniakea: Our home supercluster
 
04:11
Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space. Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means ‘immeasurable heaven’ in Hawaiian.

RNA interference (RNAi): by Nature Video
 
05:07
RNA interference (RNAi) is an important process, used by many different organisms to regulate the activity of genes. This animation explains how RNAi works and introduces the two main players: small interfering RNAs (siRNAs) and microRNAs (miRNAs). We take you on an audio-visual journey, diving into a cell to show how genes are transcribed to make messenger RNA (mRNA) and how RNAi can silence specific mRNAs to stop them from making proteins. The animation is based on the latest research, to give you an up-to-date view.

Lego Antikythera Mechanism
 
02:57
The Antikythera Mechanism: http://bit.ly/fm4oFK is the oldest known scientific computer, built in Greece at around 100 BCE. Lost for 2000 years, it was recovered from a shipwreck in 1901. But not until a century later was its purpose understood: an astronomical clock that determines the positions of celestial bodies with extraordinary precision. 

In 2010, we built a fully-functional replica out of Lego.

Method of the Year 2011: Gene-editing nucleases - by Nature Video
 
03:37
Gene-editing nucleases can make targeted and precise changes to an organism's genome. This has opened up new possibilities for the study of gene function, as well as the treatment of disease. While gene-editing nucleases have been in use since the mid-1990s, in the form of zinc finger nucleases, the more recent discovery of TALENs (transcriptor-like effector nucleases) has created new interest. In this video, Nature Methods technology editor Monya Baker explains how gene-editing nucleases work and why they were chosen as Nature Methods 'Method of the Year' for 2011.

Lumps of gold moulded into rings, coins and ingots have been highly prized for millennia. But recently, scientists have realised that tiny pieces of this precious metal – far too small to be seen by the naked eye - could also become a valued commodity. In labs around the world, gold nanoparticles are being tested as components in technology and medicines.

Inside ALS: The neurons behind the disease
 
03:28
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder that mainly affects the nerve cells (neurons), which control muscle movement. As the motor neurons degenerate, they stop sending signals to the muscles, causing progressive muscle weakness and — ultimately — death. This animation focuses on the mechanisms within the motor neurons that cause them to degenerate. By understanding these mechanisms, researchers hope to one day find a cure for ALS.

The nerve bypass: how to move a paralysed hand
 
03:38
After a broken neck left him quadriplegic, Ian Burkhart was told he would never be able to use his hands. Now he can grasp a bottle and pick up a credit card by using a computer plugged directly into his brain. Special software is able to decode his thoughts and convert them into electrical signals in his hand, bypassing the damaged nerves in his spine. Now Ian has regained an amazing degree of control over his hand, each movement stimulated by his own thoughts. The research was carried out at The Ohio State University and Battelle Memorial Institute. Chad Bouton was based at Battelle for the duration of the project. He has since moved to the Feinstein Institute.

Cat domestication: From farms to sofas

Years before they conquered the Internet, cats colonized our sofas. But they haven’t spent the last ten thousand years just snoozing. A new study reveals that tamed cats swept through Eurasia and Africa carried by early farmers, ancient mariners and even Vikings. The researchers analysed DNA from over 200 cat remains and found that farmers in the Near East were probably the first people to successfully tame wild cats 9,000 years ago, before a second wave of cat domestication a few thousand years later in ancient Egypt.

Targeting tumours: Challenges of antibody-drug conjugates
 
03:34
Treating cancer requires aggressive but targeted therapy. Some cancer drugs are too toxic because they damage healthy cells as well as tumor cells. So researchers are trying to develop ways to make sure drugs only target the right cells. One solution is to attach drugs to antibodies specific to a protein expressed on tumour cells. These drugs are called antibody-drug conjugates (ADCs). More than two dozen ADCs are currently being used in the clinic to treat diseases like Hodgkin's lymphoma and breast cancer, and researchers are developing many more. But it's taken decades to find the right combination of drug, antibody target and linker, and then make sure the right amount of ADC hits the tumor. In this 3D animation, produced by Nature Biotechnology, we hear about these challenges and the ways ADCs target cells. This content is editorially independent of sponsors.

Repairing the eardrum: The sound of self-healing
 
03:03
Ruptured eardrums are relatively common. Fortunately, small tears usually heal by themselves. But some large tears need to be repaired by a surgeon. This animation shows how a new tissue engineering technique could make that process much easier and cheaper. The technique uses a scaffold and growth factor to stimulate the eardrum’s own cells to grow over the tear.
