Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter.

Bruker’s molecular phenomics research tools enable new insights into ‘long COVID’ and post-acute metabolic abnormalities

A clinical research collaboration on COVID-19 pheno-conversion and subsequent pheno-reversion has discovered transient and persistent systemic changes of the molecular signatures in patient blood samples three months after the acute COVID-19 disease phase.

Scientists explain why space travel weakens the human immune system

Microgravity in space perturbs human physiology and is detrimental for astronaut health, a fact first realized during early Apollo missions when astronauts experienced inner ear disturbances, heart arrhythmia, low blood pressure, dehydration, and loss of calcium from their bones after their mission.

Nanopore analysis identifies pseudouridine modifications in SARS-CoV-2

In a paper recently uploaded to the preprint server bioRxiv* by Fleming, Mathewson & Burrows (May 10th, 2021), nanopore devices are developed that allow identification of the passage of pseudouridine through a protein sensor. This further allowed the group to identify five conserved pseudouridine sites on the 3’ end of SARS-CoV-2 sub-genomic RNAs, which could potentially be beneficial to the virus in immune evasion.

Researchers review materials used to design biosensors for SARS-CoV-2 detection

The SARS-CoV-2 virus is still causing a dramatic loss of human lives worldwide, constituting an unprecedented challenge for society, public health, and economy, to overcome. Currently, SARS-CoV-2 can be diagnosed in two different ways: i) antigen tests (point-of-care, POC) and ii) molecular tests (nucleic acid, RNA, or PCR-polymerase chain reaction).

Researchers create new, open-access tool for assessing infant brain health

Researchers have created a new, open-access tool that allows doctors and scientists to evaluate infant brain health by assessing the concentration of various chemical markers, called metabolites, in the brain. The tool compiled data from 140 infants to determine normal ranges for these metabolites.
