4 Oct 2021

A team of scientists has discovered a new physical phenomenon: complex braided structures made of tiny magnetic vortices known as skyrmions. Skyrmions were first detected experimentally a little over a decade ago and have since been the subject of numerous studies, as well as providing a possible basis for innovative concepts in information processing that offer better performance and lower energy consumption.

2.    Comb Breathalyzer Is Now More Sensitive to Disease Biomarkers

JILA scientists have boosted the sensitivity of their decade-old frequency comb breathalyzer a thousandfold and can detect additional biomarkers of disease — four now, with the potential for six more. When validated and engineered into a portable design, the comb system could offer real-time, noninvasive analysis of human breath to detect and monitor diseases.

3.    Low-Cost, Continuous Seismic Monitoring System

Researchers demonstrated a new method for continuously monitoring the environment just below Earth’s surface using a small seismic source and fiber-optic cables. Accurate and frequent measurements of changes in the ground enabled by the system can aid in the safe and efficient implementation of measures to fight climate change such as carbon storage and geothermal energy generation.

4.    Dwarf Planet Vesta a Window to the Early Solar System

The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent papers use data from meteorites derived from Vesta to resolve the “missing mantle problem” and push back our knowledge of the solar system to just a couple of million years after it began to form.

5.    Tiny Bubbles Can Be Future Treatment for Inflammation

7 Oct 2021

Scientists hope that tiny sacs of material excreted by cells – so-called extracellular vesicles – can be used to deliver drugs inside the body. Researchers now show that these nano-bubbles can transport protein drugs that reduce inflammation caused by different diseases. The technique shows promising results in animal models.

6.    Rover Images Confirm Jezero Crater Is an Ancient Martian Lake

7 Oct 2021

The first scientific analysis of images taken by NASA’s Perseverance rover has now confirmed that Mars’ Jezero crater — which today is a dry, wind-eroded depression — was once a quiet lake, fed steadily by a small river some 3.7 billion years ago.
