Chronic sleep loss could be linked to one sign of premature aging in the body, according to a new study published in Communications Biology. Using fitness tracker data, researchers showed that consumer sleep trackers can shine a light on the high costs of not getting enough sleep.

Growing evidence from mouse studies suggests that a healthy microbiome might improve poststroke outcomes.

Artificial muscles will power the soft robots and wearable devices of the future. But more needs to be understood about the underlying mechanics of these powerful structures in order to design and build new devices.

Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have uncovered some of the fundamental physical properties of artificial muscle fibers.

“Thin soft filaments that can easily stretch, bend, twist or shear are capable of extreme deformations that lead to knot-like, braid-like or loop-like structures that can store or release energy easily,” said L. Mahadevan, the Lola England de Valpine Professor of Applied Mathematics, of Organismic and Evolutionary Biology, and of Physics. “This has been exploited by a number of experimental groups recently to create prototypical artificial muscle fibers. But how the topology, geometry and mechanics of these slender fibers come together during this process was not completely clear. Our study explains the theoretical principles underlying these shape transformations, and sheds light on the underlying design principles.”

Is it accurate?

Does it really show your so-called “biological vs. chronological” age?

And once you do get your results, how can you lengthen your telomeres?

Polymorphism is a remarkable concept in chemistry, materials science, computer science, and biology. Whether it is the ability of a material to exist in two or more crystal structures, a single interface connecting to two different entities, or alternative phenotypes of an organism, polymorphism determines function and properties. In materials science, polymorphism can be found in an impressively wide range of materials, including crystalline materials, minerals, metals, alloys, and polymers. Here we report on polymorphism in a liquid crystal. A bent-core liquid crystal with a single chiral side chain forms two structurally and morphologically significantly different liquid crystal phases solely depending on the cooling rate from the isotropic liquid state. On slow cooling, the thermodynamically more stable oblique columnar phase forms, and on rapid cooling, a not heretofore reported helical microfilament phase. Since structure determines function and properties, the structural color for these phases also differs.

Physicists have watched a chain of 15 amino acids interfere with itself, in an experiment that paves the way for a new era of quantum biology.

ROME (Thomson Reuters Foundation) — It may sound like science fiction, but in a few short years the family dinner table may be laden with steak from a printer and other proteins produced from air, methane or volcanic microbes.

With the explosive success of vegan beef and burger substitutes developed by Beyond Meat and Impossible Foods, the alternative protein sector just keeps growing.

According to investment bank Barclays, alternative meat sales could reach $140 billion — or 10% of the global meat industry — within a decade, or a 10-fold increase from current levels.

A recent study shows that male emerald ash borers infected with a deadly fungus readily transmit the fungus when mating, opening doors for future biological control efforts.

Mice without healthy gut bacteria have a hard time moving on from fearful situations, adding to evidence that the microbiome influences how the mammalian brain works.
