Epigenetic factors play a role in senescence
Researchers from the Perelman School of Medicine at the University of Pennsylvania have found that epigenetic factors play a role in senescence. Epigenetic factors act...
Bioengineers invent portable device for common kidney tests
A lightweight and field-portable device invented at UCLA that conducts kidney tests and transmits data through a smartphone attachment may significantly reduce the need for...
Scientists have grown a tiny brain in a dish
Scientists at the Institute of Molecular Biotechnology in Vienna, Austria, have grown three-dimensional human brain tissues from stem cells. The tissues form discrete structures that...
Human brain-to-brain interface
University of Washington researchers have performed what they believe is the first noninvasive human-to-human brain interface, with one researcher able to send a brain signal...
‘Cyborg’: Growing Artificial Tissues With Embedded Nanoscale Sensors
A multi-institutional research team has developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks -- which mark the first...
Researchers Report Breakthrough in DNA Editing Technology
Scientists at The Scripps Research Institute (TSRI) have found a way to apply a powerful new DNA-editing technology more broadly than ever before. “This is...
Detecting early-stage malarial infection
New prototype device recognizes electrical properties of infected cells as signatures of disease. Researchers at MIT have found a way to detect early-stage malarial infection...
Brainwaves Through the Ear
Neuroscientists often use electroencephalography (EEG) as an inexpensive way to record electrical signals in the brain. Though it would be useful to run these recordings...
Digital Taste Interface
Several interactive systems can be found in the literature for simulating taste sensations, especially in the area of Human-Computer Interaction (HCI). However, these solutions mostly...
Harvard Stem Cell researchers create cells that line blood vessels
In a scientific first, Harvard Stem Cell Institute scientists have successfully grown the cells that line the blood vessels—called vascular endothelial cells—from human induced pluripotent...
Building Better Brain Implants
On August 20, JoVE, the Journal of Visualized Experiments will publish a technique from the Capadona Lab at Case Western Reserve University to accommodate two...
Computer can read letters directly from the brain
By analysing MRI images of the brain with an elegant mathematical model, it is possible to reconstruct thoughts more accurately than ever before. In this...
Nanoparticles reprogram immune cells to fight cancer
Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize...
Bioengineers closer to viable organ implants
Researchers at the Institute of Bioengineering and Nanotechnology (IBN) have developed a simple method of organizing cells and their microenvironments in hydrogel fibers. Their unique...
