Scientists have developed an ingestible capsule dotted with sensors that can detect pressure in a patient’s guts and detect points of failure.

The ingestible system will give colorectal medical teams an unprecedented understanding of the movement of a patient’s digestive tract, or lack thereof. Instead of simply taking images of inside the guts, the system will sense whether it’s contracting, how much pressure is exerted and exactly where it might be inactive.

The system has been tested in a synthetic gut and animals. A patent for the technology is pending.

The team from Heriot-Watt University and the University of Birmingham, with colleagues from the University of Edinburgh, have reported the...

Astrophysicist’s Research could provide a Hint in the Search for Dark Matter

Dark matter is one of science’s greatest mysteries. It doesn’t absorb, reflect or emit light, so we can’t see it. But its presence is implied by the gravitational effects it appears to have on galaxies.

Although dark matter makes up about 85% of the cosmos, scientists know very little about its fundamental nature.

Theories abound, and research by Clemson University postdoctoral fellow Alex McDaniel provides some of the most stringent constraints on the nature of dark matter yet. His research also reveals a small hint of a signal that if real, could be confirmed sometime in the next decade or so.

The work is published in the journal Physical Review D.

“With data collection and new discoveries in the future, thi...

Team develops Fluid Biomarker for Early Detection of Amyotrophic Lateral Sclerosis, ALS and Frontotemporal Dementia

Johns Hopkins Medicine-led team develops fluid biomarker for early detection of ALS and FTD
A Johns Hopkins Medicine-led team has developed a fluid biomarker that may one day detect two degenerative diseases, ALS and FTD, before symptoms appear. The biomarker locates a protein associated with the loss of function for the TDP-43 protein (seen as a molecular model in this image), an abnormality linked to people who develop ALS or FTD.

Two progressively degenerative diseases, amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig’s disease) and frontotemporal dementia (FTD, recently in the news with the diagnoses of actor Bruce Willis and talk show host Wendy Williams), are linked by more than the fact that they both damage nerve cells critical to normal functioning—the former affecting nerves in the brain and spinal cord ...

Performing a new task based solely on verbal or written instructions, and then describing it to others so that they can reproduce it, is a cornerstone of human communication that still resists artificial intelligence (AI).

A team from the University of Geneva (UNIGE) has succeeded in modeling an artificial neural network capable of this cognitive prowess. After learning and performing a series of basic tasks, this AI was able to provide a linguistic description of them to a “sister” AI, which in turn performed them. These promising results, especially for robotics, are published in Nature Neuroscience.

Performing a new task without prior training, on the sole basis of verbal or written instruc...
