Researchers have filled two knowledge gaps: The vacuoles of plant cells can be excited and the TPC1 ion channel is involved in this process. The function of this channel, which is also found in humans, has been a mystery so far.
Human body communication (HBC) uses the human body to transmit power and data, much like the internet. Because it's a smaller and closed network, it has the benefit of being more secure and power efficient. In a recent study, a group of Japanese researchers used an equivalent circuit model to examine how different parameters affect HBC transmission characteristics.
The flow of traffic through our nation's highways and byways is meticulously mapped and studied, but less is known about how materials in cells travel. Now, a team of researchers at the University of Missouri is challenging prior theories about how material leaves the inside of an E.coli cell. This discovery could have important implications for how we treat diseases.
How does the brain's circuitry adjust itself to make sense of the world despite the hugely different signals it receives? Scientists from the National Centre for Biological Sciences (NCBS), Bangalore, believe that they have discovered the root causes of this phenomenon--called normalization--to be based on two properties of brain circuits that they have demonstrated in mouse brains.
A person's body composition could influence the difference between the amount of energy they spend while sitting versus standing, according to new research published in the open-access journal PLOS ONE. Conducted by Francisco J. Amaro-Gahete of the University of Granada, Spain, and colleagues, this work adds to mounting evidence that more energy is expended while standing than while sitting or lying down.
A University of Houston biomedical engineer reports in eNeuro that a brain-computer interface, a form of artificial intelligence, can sense when its user is expecting a reward by examining the interactions between single-neuron activities and the information flowing to these neurons. The work represents a significant step forward for prosthetics that perform more naturally.
Stroke, one of the leading causes of death worldwide, is normally caused by poor blood flow to the brain, or cerebral ischemia. This must be diagnosed within the first few hours of the stroke for treatment to be effective. Researchers have developed a device that uses near-infrared light to monitor blood flow. The hybrid instrument, which relies on the combination of two light measurement techniques, could be used to quickly and noninvasively diagnose cerebral ischemia.
The shield-like tail segment, or telson, of the smasher mantis shrimp is a multiscale structure with ridges on the outside and a structure shaped like a spiral staircase on the inside. It's inspiring a new class of lightweight, impact-resistant materials for helmets, cars, and more
EPFL biophysicists have taken a systematic look into how bacterial biofilms are affected by fluid flow. The findings can give us clues about the physical rules guiding biofilm architecture, but also about the social dynamics that shape evolution.
For the first time, Colorado State University scientists Tim Stasevich and Brian Munsky have developed detailed imaging technology and computational analyses to visualize, quantify and understand frameshifting mechanisms at the level of single molecules in living cells.
