Craig Montell is a professor at the University of California, Santa Barbara, who helped lead the research. He said in a statement that by removing the two eye receptors, the team was able to “eliminate CO2-induced target recognition without causing blindness.”

Female Aedes aegypti search out blood meals in humans to develop eggs. They use several different senses to find those meals. One of the main identifying tools is the smell of carbon dioxide (CO₂). When a human breathes out CO₂, the mosquitoes become more active and begin looking for targets to bite.

The research team said this search generally begins with the mosquito flying toward the direction of the released CO₂. When seeking out targets, the insects search for dark objects. Once the mosquitoes are within close range, they can also sense heat from skin and additional skin smells to help guide them to a human.

Why do so many people get frustrated with their “high-tech” prostheses? Though sophisticated robotics allow for prosthetic joints that can do everything a human can and more, the way we control robotic machines right now doesn’t allow us to operate them as naturally as you would a biological hand. Most robotic prostheses are controlled via metal pads on the skin that indirectly measure muscle action and then make some assumptions to determine what the person wants to do. Whil… See More.

We plan to use MM to provide natural control over prosthetic limbs by leveraging the human body’s proprioception. When you wiggle one of your fingers, your brain senses muscle lengths, speeds, and forces, and it uses these to figure out the position of that finger. This is called body awareness, or proprioception. When someone receives an amputation, if their muscle connections are maintained with what is called the “AMI technique,” their brain still perceives muscle flexion as it relates to joint movement, as if their limb was still present. In other words, they are sensing movement of a phantom limb. To give an amputee intuitive control over a robotic prosthesis, we plan to directly measure the muscle lengths and speeds involved in this phantom limb experience and have the robot copy what the brain expects, so that the brain experiences awareness of the robot’s current state. We see this technique as an important next step in the embodiment of the prosthetic limb (the feeling that it is truly part of one’s body).

Notably, the tracking of magnetic beads is minimally invasive, not requiring wires to run through the skin boundary or electronics to be implanted inside the body, and these magnetic beads can be made safe to implant by coating them in a biocompatible material. In addition, for muscles that are close to the skin, MM can be performed with very high accuracy. We found that by increasing the number of compass sensors we used, we could track live muscle lengths close to the surface of the skin with better than millimeter accuracy, and we found that our measurements were consistent to within the width of a human hair (about 37 thousandths of a millimeter).

Blockchains work like DNA, says a new study. Its instructions are replicated across thousands of “nodes,” much as DNA is replicated in cells.

Northwestern Medicine investigators have discovered that a subset of proteins in mitochondria of brain and heart cells are long-lived, supporting the long-term stability of mitochondrial complex architecture.

The study, published in the Journal of Cell Biology, was led by Jeffrey Savas, PhD, assistant professor in the Ken & Ruth Davee Department of Neurology’s Division of Behavioral Neurology, of Medicine the in Division of Nephrology and Hypertension, and of Pharmacology.

Previous work led by Savas discovered that nuclear pore complex proteins in post-mitotic neurons are exceptionally long-lived and persist for months in mouse and rat brains. These proteins, termed long-lived proteins, or LLPs, provide long-term stability and structure to the nuclear pore and subsequently to the nuclear envelope of neurons; however, this concept had never been considered for other intracellular organelles, until now.

Sharp wave-ripples from the hippocampus are shown to modulate peripheral glucose homeostasis in rats, offering insights into the mechanism that links sleep disruption and blood glucose regulation in type 2 diabetes.

Deploying two unrelated CRISPR nucleases in tandem, with multiplexed CRISPR RNAs and a chemically stabilized activator, creates a simple, one-step assay that can rapidly detect attomolar concentrations of RNA without needing target amplification.
