Research sheds light on friction, lubrication and wear in cartilage
11:25 a.m., Aug. 24, 2015–Osteoarthritis, which affects some 27 million people in the U.S. alone, occurs when the protective cartilage on the ends of bones wears down over time.
The availability of artificial cartilage would be life changing for those suffering from...Read More »
A new 3D printing technique allows researchers to replicate biological structures, which could be used for tissue regeneration and replica organs.
Imperial College London researchers have developed a new method for creating 3D structures using cryogenics (freezing) and 3D printing techniques.
This builds on previous...Read More »
Nearly 90 percent of the 4.5 million workers in the Los Angeles area spend an average of 60 minutes each day commuting on a roadway or railway, according to the U.S. Census Bureau.
When researchers from the USC Viterbi School of Engineering set out to study the...Read More »
Engineers predict how flowing fluid will bend tiny hairs that line blood vessels and intestines.
Our bodies are lined on the inside with soft, microscopic carpets of hair, from the grassy extensions on our tastebuds, to fuzzy beds of microvilli in our stomachs, to superfine protein strands throughout our blood vessels....Read More »
The characteristics of human skin are heavily dependent on the hydration of the tissue – in simple terms, the water content. This also changes its interaction with textiles. Up to now, it has only been possible to determine the interaction between human skin and textiles by means of clinical trials...Read More »
Using a thermal camera, scientist Katarina Leijon Sundqvist succeeds, in a quick and simple way, to study differences in blood circulation in the hands of people who suffer from Raynaud’s phenomenon, also known as “white fingers”, and those who do not suffer from this phenomenon.
Blood circulation and the heat exchange...Read More »
Eight years ago, Ted Adelson’s research group at MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) unveiled a new sensor technology, called GelSight, that uses physical contact with an object to provide a remarkably detailed 3-D map of its surface.
Now, by mounting GelSight sensors on the grippers of robotic arms,...Read More »
Sesame oil might make a viable and sustainable alternative to mineral oil as an industrial lubricant, according to research published in the International Journal of Agricultural Resources, Governance and Ecology.

A simple ball of cells is the starting point for humans – and zebrafish. At the end of embryonic development, however, a fish and a human look very different. The biochemical signals at play have been studied extensively. How mechanical forces on the other hand shape the embryo is the...Read More »
Superlubricity is a state of vanishing sliding friction. It has been reported in glycerol/water mixture lubricated contacts, graphene-gold interface, interface in presence of graphene and in other conditions. Increasing number of reports on superlubricity in macroscale is driven by the need of energy costs...Read More »
Superlubricity is a state of low friction, broadly defined as the state with the coefficient of friction lower than 0.01. This level is not achievable with classical lubrication mechanisms and currently other methods are being searched for. Existing methods of superlubricity require specific conditions, material combinations or limited to...Read More »
Darvin’s theory of evolution is widely held concept which states that all the life has evolved from a common ancestor: fruits, animals, trees, flowers. During the gradual process of evolution, beneficial random genetic mutations in simple creatures accumulated and resulted in more complex species. The process of accumulation of only...Read More »
