It has succeeded in developing the first human heart cells that can contract in response to certain types of light. In a laboratory at Stanford University, USA, Dr. Oscar Abilez team has managed to design first human heart cells that contract to the rhythm of light using a technology known as optogenetics.
These cells are cardiomyocytes. They are scheduled to contract and expand again and again, thus beating to death. In the laboratory, such cells undergo rhythmic beats at a rate of one per second. However, you can reset your pulse rate by projecting blue light, which is operated by a switch. Read the rest of this entry »
The slime mold, a single-celled organism which may become multi-cellular under environmental pressures that threaten their survival, have, according to a new discovery, a structure of tissue so far was only known in more sophisticated animals. In addition, two proteins that need the slime of mold to form this structure are similar to those that perform the same function in more complex animals.
The slime mold spends most of his life as a unicellular organism, living in the soil and feed on bacteria.
However, when food is scarce, thousands of cells that gather rust forming between all kinds of mound. Read the rest of this entry »
Cataracts, an eye problem that clouds the vision and affects millions of people in the developing world each year could be eliminated quickly and more cleanly. A new method that combines the precision cutting of a “femtosecond laser” with a novel technique for three-dimensional image could achieve this breakthrough.
Their leaders, a team of scientists from several institutions and universities led by Daniel Palanker, Stanford University, offers details on an article journal Translational Science Medicine.
Unlike conventional lasers that melt and boil their objectives, femtosecond lasers operating at short light pulses and high energy. Therefore, they are able to transform their target plasma that dissipates quickly without damaging the fabric edges. As a result, cut around the eye lens is smooth and precise.
