Dietary Fiber Helps Clump Material in Your Gut
Dietary Fiber Helps Clump Material in Your Gut
Food, microbes, and medicine all clump together as they move through our gut. Sticky molecules secreted into our intestines bind the gut particles in the same way that flour holds a ball of dough together. Now a new mice-based study from Caltech is showing that dietary fiber also plays a role in clumping.

Researchers Develop Method To ID Diseases with Less Data
As artificial intelligence systems learn to better recognize and classify images, they are becoming highly reliable at diagnosing diseases, such as skin cancer, from medical images. But as good as they are at detecting patterns, AI won't be replacing your doctor any time soon. Even when used as a tool, image recognition systems still require an expert to label the data, and a lot of data at that: it needs images of both healthy patients and sick patients.

Making Green Cars Greener
CMU Researchers Examine Ways To Recycle Electric Vehicle Batteries The widespread implementation of electric vehicles will go a long way toward eliminating the greenhouse gas emissions of the transportation sector. But these emissions don't just come from the tailpipe. There's another major culprit of greenhouse gases, one that the electric vehicle industry might need some help from policymakers to avoid: battery recycling.

UCLA faculty voice: Adolescents have a fundamental need to contribute
Andrew Fuligni is a professor of psychiatry and psychology at UCLA. This article appeared in The Conversation. No longer children but not yet adults, adolescents need opportunities to learn and prepare for their entrance into the broader society. But, as schooling increasingly extends the adolescent period and teenagers get dismissed as supposedly selfish and irresponsible, has society forgotten an important developmental need of our youth?

Is lab-grown meat really better for the environment?
Growing meat in the laboratory may do more damage to the climate in the long run than meat from cattle, according to new research. In a first-of-its-kind study from the LEAP (Livestock, Environment and People) programme at the Oxford Martin School, the climate-change impact of several production methods for lab-grown and farmed beef was assessed accounting for the differing greenhouse gases produced.

Extinguishing fear memories relies on an unusual change to DNA
Researchers at The University of Queensland have discovered a DNA modification that enhances our ability to extinguish fear. The findings, published , could help guide the development of new treatments for fear-related anxiety disorders. Professor Timothy Bredy of UQ's Queensland Brain Institute (QBI) said while fear is an important survival mechanism which uses cues in the environment to prompt certain responses, so too is the ability to inhibit fear when it's no longer needed.

Rosetta's comet sculpted by stress
Rosetta’s comet sculpted by stress
Feeling stressed? You're not alone. ESA's Rosetta mission has revealed that geological stress arising from the shape of Comet 67P/Churyumov-Gerasimenko has been a key process in sculpting the comet's surface and interior following its formation. Small, icy comets with two distinct lobes seem to be commonplace in the Solar System, with one possible mode of formation a slow collision of two primordial objects in the early stages of formation some 4.5 billion years ago.

Superconduction: Why does it have to be so cold?
Superconduction: Why does it have to be so cold?
Currently, there is no precise computation method to describe superconducting materials. TU Wien has now made a major advance towards achieving this goal and, at the same time, has furthered an understanding of why conventional materials only become superconducting at around -200°C Why does it always have to be so cold? We now know of a whole range of materials that ' under certain conditions ' conduct electrical current entirely without resistance.
