American Journal of Botany Researchers apply FIB-SEM technology to 3-D plant cell architecture imaging Plant cells are beginning to look a lot different to Dr. A. Bruce Cahoon and his colleagues at Middle Tennessee State University (MTSU). They've adopted a new approach that combines the precision of an ion beam with the imaging capabilities of an electron beam to zoom in at micron-level resolution. Scientists who work with nanodevices have used focused ion beam–scanning electron...

'Heart Disease-On-A-Chip' Made From Patient Stem Cells
2014-05-12 03:22:55

[ Watch The Video: Cardiac Tissue Contractile Strength Differences Shown Using “Heart-On-A-Chip” ] Harvard University Harvard scientists have merged stem cell and 'organ-on-a-chip' technologies to grow, for the first time, functioning human heart tissue carrying an inherited cardiovascular disease. The research appears to be a big step forward for personalized medicine, as it is working proof that a chunk of tissue containing a patient's specific genetic disorder can be replicated...

Bacterial Biofilms Used To Create Lifelike Materials
2014-03-24 04:29:52

redOrbit Staff & Wire Reports - Your Universe Online By drawing inspiration from the way in which minerals, living cells and other substances combine to form bone, a team of MIT engineers have created a type of “living material” out of bacterial cells, according to research appearing in Sunday’s edition of the journal Nature Materials. Lead author Allen Chen, an MIT-Harvard MD-PhD student, and his colleagues coaxed those cells to produce biofilms capable of incorporating...

Our cells don’t live in a vacuum. They are surrounded by a complex, nurturing matrix that is essential for many biological functions, including growth and healing. In all multicellular organisms, including people, cells make their own extracellular matrix. But in the lab, scientists attempting to grow tissue must provide a scaffold for cells to latch onto as they grow and proliferate. This engineered tissue has potential to repair or replace virtually any part of our bodies....

New Method Enables Scientists To Print Tissue Constructs With Blood Vessels
2014-02-19 15:24:58

Wyss Institute for Biologically Inspired Engineering at Harvard A new bioprinting method developed at the Wyss Institute for Biologically Inspired Engineering at Harvard University and the Harvard School of Engineering and Applied Sciences (SEAS) creates intricately patterned 3D tissue constructs with multiple types of cells and tiny blood vessels. The work represents a major step toward a longstanding goal of tissue engineers: creating human tissue constructs realistic enough to test...

Researchers Help Develop A Dynamic Model Of Tissue Failure
2013-12-12 17:45:57

University of Pennsylvania The idea of growing replacement tissue to repair an organ, or to swap it out for an entirely new one, is rapidly transitioning from science fiction to fact. Tissue engineering techniques are improving in their ability to generate three-dimensional masses of cells and provide them with vascular systems for keeping them alive, but a more mathematically rigorous approach for designing these tissues is still needed. Researchers at the University of Pennsylvania,...

Measuring Life's Tugs And Nudges
2013-12-09 19:12:18

Wyss Institute for Biologically Inspired Engineering at Harvard Tiny oil droplets help measure mechanical forces produced by living cells that shape tissues and organs; new method could improve diagnosis of cancer, hypertension, and many other diseases As embryonic tissue develops, cells push and pull on each other, and they must do so correctly for the tissue to develop properly. Now scientists at Harvard University have devised the first method to measure these forces in...

Scientists Create Functional Lungs Using Human Stem Cells
2013-12-02 12:40:54

Lee Rannals for redOrbit.com - Your Universe Online Scientists have used human stem cells to create functional lung and airway cells, according to a study published in the journal Nature Biotechnology. The latest research, reported by a team from Columbia University Medical Center (CUMC), could have significant potential for modeling lung disease, screening drugs, studying human lung development, and generating lung tissue for transplantation. "Researchers have had relative success...

Scientists at Karolinska Institutet in Sweden have discovered that two separate species of salamander differ in the way their muscles grow back in lost body parts. Their findings on the species-specific solutions, published in the scientific periodical Cell Stem Cell, demonstrate there is more than one mechanism of tissue regeneration. To carry out their study, the scientists labelled different cell types in two species of salamander in order to ascertain what kinds of cell give rise to...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
