Researchers have improved the transfer efficiency between quantum information carriers, in a manner that’s based on well-established nanoscience and is compatible with upcoming advanced communication technologies.

Information storage and transfer in the manner of simple ones and zeros — as in today’s classical computer technologies — is insufficient for quantum technologies under development. Now, researchers from Japan have fabricated a nanoantenna that will help bring quantum information networks closer to practical use.

In a study recently...

Carbon Dioxide Cold Traps on the Moon are Confirmed for the First Time

A view of the lunar south pole, where newly confirmed carbon dioxide cold traps are located, according to new research in Geophysical Research Letters. Future missions on the Moon may target this region to find out more about the resources that may exist there.

The traps likely contain solid carbon dioxide that could be used to sustain robot or human presence on the moon. After decades of uncertainty, researchers have confirmed the existence of lunar carbon dioxide cold traps that could potentially contain solid carbon dioxide. The discovery will likely have a major influence in shaping future lunar missions and could impact the feasibility of a sustained robot or human presence on the moon.

In the permanently shadowed regions at the poles o...

Diet Trumps Drugs for Anti-Aging and Good Metabolic Health

A study comparing the impact of diet versus drugs on the inner workings of our cells has found nutrition has a much stronger impact.

The pre-clinical study by the University of Sydney’s Charles Perkins Centre suggests the makeup of our diet could be more powerful than drugs in keeping conditions like diabetes, stroke and heart disease at bay.

Conducted in mice, the research showed nutrition (including overall calories and macronutrient balance) had a greater impact on ageing and metabolic health than three drugs commonly used to treat diabetes and slow down ageing.

The findings are published in Cell Metabolism.

The research builds on the team’s pioneering work in mice and humans demonstrating the protective role of diet and specific combinations of proteins, fats and carbo...

Imagine your car starting the moment you get in because it recognizes the jacket you’re wearing. Consider the value of a hospital gown that continuously measures and transmits a patient’s vital signs. These are just two applications made possible by a new “body area network”-enabling fabric invented by engineers at the University of California, Irvine.

In a paper published recently in Nature Electronics, researchers in UCI’s Henry Samueli School of Engineering detail how they integrated advanced metamaterials into flexible textiles to create a system capable of battery-free communication between articles of clothing and nearby de...
