The Workhorse of the Cell: Kinesin
Masterpieces of microengineering, kinesins are motorized transport machines that move cellular materials to their correct locations in the cell so they can perform their functions. Kinesins have two f...
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...
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 ...
Nobel Prize for chemistry given to developers of molecular machines
Nobel Prize for chemistry given to developers of molecular machines, Sourav Roy has the latest details.
Organisms might be quantum machines
Few of us really understand the weird world of quantum physics – but our bodies might take advantage of quantum properties
A chemically powered autonomous molecular nanomotor
A group of scientists at the University of Manchester in the U.K. has developed the first chemically powered autonomous molecular nanomotor—the motor mechanism is itself a transport medium ...
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 ...
Surfing A Wake Of Light
For the first time, Harvard researchers have created wakes of light-like waves moving on a metallic surface, called surface plasmons, and demonstrated that they can be controlled and steered. The cre...
Quantum Technology Probes Ultimate Limits Of Vision
An experiment to test the limits of human vision has provided the strongest evidence yet that our eyes can sense flashes of light as feeble as three photons. The study, which involves firing photons i...
New Evidence Emerges On The Origins Of Life On Earth
In the beginning, there were simple chemicals. And they produced amino acids that eventually became the proteins necessary to create single cells. And the single cells became plants and animals. Recen...
New Species May Arise From Random Mutations
This controversial proposal stems from efforts by Hedges and collaborators to build the world’s most comprehensive tree of life — a chart plotting the connections among 50,000 species of Earth’s vast ...
Quantum Criticality In Life's Proteins
Stuart Kauffman, from the University of Calgary, and several of his colleagues have recently published a paper on the Arxiv server titled 'Quantum Criticality at the Origins of Life'. The idea of a qu...
Recently Developed Molecular 3D Printer Will Bring Chemistry Into A New Era
This new machine will greatly benefit drug research and other molecule-based technologies as it helps quicken the process of analyzing different compounds and understanding how they respond to differe...
Limpet teeth set new strength record
Engineers find that limpets' tiny teeth are made of the strongest biological material ever tested.
Surface Plasmon Resonance Explained
This video explains what Surface Plasmon Resonance technology is, how it is used to detect small molecules and their interaction with other proteins. For mor...
Molecular machine
A molecular machine, or nanomachine, is any discrete number of molecular components that produce quasi-mechanical movements (output) in response to specific stimuli (input). The expression is often mo...
