Drew Berry: Animations of unseeable biology
http://www.ted.com We have no ways to directly observe molecules and what they do -- Drew Berry wants to change that. At TEDxSydney he shows his scientifically accurate (and entertaining!) animations ...
A Day in the Life of a Motor Protein
The primary aim of the Hoogenraad research lab at the University of Utrecht, the Netherlands, is to understand how intracellular protein transport underlies the development and function of nerve cells...
Naked mole rats' 'plant-like' behaviour to avoid oxygen starvation could help stroke victims
Naked mole rats are every bit as strange as they sound: cold-blooded mammals who can survive for up to 18 minutes without oxygen. Learn more from ScienceTake...
The science is in: Exercise isn’t the best way to lose weight
Why working out is great for health, but not for weight loss, explained in five minutes.
Building Living, Breathing Supercomputers
The substance that provides energy to all the cells in our bodies, Adenosine triphosphate (ATP), may also be able to power the next generation of supercomputers. That is what an international team of ...
Material Inspired By Nature Could Turn Water Into Fuel
Scientists have theoretically designed a new material that could help supply the world with clean energy by turning water into fuel, using just the power of the sun. Chemists at the University of Read...
Quantum Physics Meets Genetic Engineering
Nature has had billions of years to perfect photosynthesis, which directly or indirectly supports virtually all life on Earth. In that time, the process has achieved almost 100 percent efficiency in t...
A Metabolic Master Switch Underlying Human Obesity Discovered
Obesity is one of the biggest public health challenges of the 21st century. Affecting more than 500 million people worldwide, obesity costs at least $200 billion each year in the United States alone, ...
Yale Team Sheds Light On Century-Old Biochemical Mystery
Given plenty of glucose and oxygen, yeast and cancer cells do not burn it all to produce energy but convert much of it to the byproducts ethanol and lactate, respectively. In the 1920s Nobel laureate ...
New Study Uncovers How Common White Fat Can Be Turned Into Energy-Nurning Brown Fat In Humans
Researchers from The University of Texas Medical Branch at Galveston have discovered, for the first time in humans, that the widely reviled energy storing white fat can be turned into an energy burnin...
Why Tumors Need Respiration
Mitochondria are well known for their role as powerhouses in our cells, using respiration to release the energy in the food we eat and trapping that energy in the molecule adenosine triphosphate, or A...
How Tiny Plankton Brighten The Clouds Over Southern Ocean
Scientists have used NASA satellite data to determine why clouds are more reflective in the Southern Ocean than in other regions. Researchers have uncovered findings in the Southern Ocean that reaffir...
Spectrum Of Life: Nonphotosynthetic Pigments Could Be Biosignatures Of Life On Other Worlds
To find life in the universe, it helps to know what it might look like. If there are organisms on other planets that do not rely wholly on photosynthesis — as some on Earth do not — how might those wo...
Ocean's Hidden World Of Plankton Revealed In 'Enormous Database'
The hidden world of the ocean's tiniest organisms has been revealed in a series of papers published in the journal Science. An international team has been studying samples of plankton collected during...
Major Depression Leaves A Metabolic Mark
Major depression comes with an unexpected metabolic signature, according to new evidence reported in the Cell Press journal Current Biology on April 23. The findings in humans and mice offer new insig...

Active transport
Active transport is the movement of molecules across a cell membrane in the direction against their concentration gradient, i.e. moving from an area of lower concentration to an area of higher concent...
Cellular transport
A membrane transport protein (or simply transporter) is a membrane protein involved in the movement of ions, small molecules, or macromolecules, such as another protein, across a biological membrane. ...
Motor protein
Motor proteins are a class of molecular motors that are able to move along the surface of a suitable substrate. They are powered by the hydrolysis of ATP and convert chemical energy into mechanical wo...
Axoplasmic transport
Axoplasmic transport, also called axonal transport, is a cellular process responsible for movement of mitochondria, lipids, synaptic vesicles, proteins, and other cell parts (i.e. organelles) to and f...
