Machine learning increases resolution of eye imaging technology
Biomedical engineers have devised a method for increasing the resolution of optical coherence tomography down to the single micrometer in all directions, even in a living patient.
3D organ bioprinting gets breath of fresh air
Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs with a breakthrough technique for bioprinting tissues.
Ability of wearable technology to detect atrial fibrillation
Researchers from the Stanford University School of Medicine presented preliminary results of the Apple Heart Study, an unprecedented virtual study with over 400,000 enrolled participants.
Stanford, Apple describe heart study with over 400,000 participants
Over 400,000 people have enrolled in a study being conducted by researchers at Stanford and Apple to determine whether a wearable technology can identify irregular heart rhythms suggestive of atrial fibrillation.
Vagus nerve stimulation can reverse brain inflammation after surgery
Scientists show in a mouse model that a current treatment for seizures can also reverse brain inflammation, such as inflammation after surgery, and the subsequent confusion or cognitive decline that results.
Safer, more efficient rechargeable batteries
Materials scientists have sussed out the physical phenomenon underlying the promising electrical properties of a class of materials called superionic crystals. A better understanding of such materials could lead to safer and more efficient rechargeable batteries than the current standard-bearer of lithium ion.
Gut branches of the vagus nerve essential for reward and motivation
A novel gut-to-brain neural circuit establishes the vagus nerve as an essential component of the brain system that regulates reward and motivation, according to research.
Stretchy wires for the future
Scientists have teamed up to create stretchable, flexible wires that conduct current and change colors to indicate they're about to reach the breaking point. Future uses could be wearable electronics, biomedical devices and soft robots.
ENGIE to build 8 hybrid solar power plants in Gabon
ENGIE has signed an agreement with CDC, the Gabonese financial institution Caisse des Dépôts et Consignations, to deploy eight hybrid solar power plants in Gabon, representing a combined capacity of 2.2 MW.
Biomaterial helps regrow brain tissue after stroke in mice
New stroke-healing gel helped regrow neurons and blood vessels in mice with stroke-damaged brains, hinting at what may someday be a new therapy for stroke in people.
Why a robot can't yet outjump a flea
When it comes to things that are ultrafast and lightweight, robots can't hold a candle to the fastest-jumping insects and other small-but-powerful creatures. New research could help explain why nature still beats robots, and describes how machines might take the lead.
Stretchable, twistable wires for wearable electronics
The exercise-tracking power of a Fitbit may soon jump from your wrist and into your clothing. Researchers are seeking to embed electronics such as fitness trackers and health monitors into our shirts, hats, and shoes. But no one wants stiff copper wires or silicon transistors deforming their clothing or poking into their skin.
Using drones to feed billions
As our population continues its rapid growth, food is becoming increasingly scarce. By the year 2050, we will need to double our current food production to feed the estimated 9.6 million mouths that will inhabit Earth.
Laser evaporation technology to create new solar materials
Materials scientists have developed a method to create hybrid thin-film materials that would otherwise be difficult or impossible to make. The technique could be the gateway to new generations of solar cells, light-emitting diodes and photodetectors.
Blood testing via sound waves may replace some tissue biopsies
Cells secrete nanoscale packets called exosomes that carry important messages from one part of the body to another. Scientists have now devised a way to intercept these messages, which could be used to diagnose problems such as cancer or fetal abnormalities.
