Obesity is in your head: MRI and weight gain clues

Date: Sep 1, 2018

Author: David Bradley

An examination of magnetic resonance imaging (MRI) and cognitive test data from 1,200 individuals, supplied as part of the Human Connectome Project shows that when it comes to weight gain, the problem may be mostly in our heads and in our genes.

Nano-actuator: SERS benefits

Date: Sep 1, 2018

Author: David Bradley

Surface-enhanced Raman spectroscopy (SERS) and related techniques could benefit from the development of a novel nanoactuator system, where conformation of biomolecule can be tuned by electric field and probed using optical properties of gold nanoparticle.

Journal Highlight: Triggering of cancer cell cycle arrest by a novel scorpion venom‐derived peptide — Gonearrestide

Date: Aug 20, 2018

Author: spectroscopyNOW

A novel scorpion venom‐derived peptide that has been identified in an in‐house constructed scorpion venom library through a combination of high‐throughput NGS transcriptomics and MS/MS proteomics inhibited the growth of primary colon cancer cells and solid tumours by triggering cell cycle arrest.

Ageing proteins: Plasma biomarkers in healthy people

Date: Aug 15, 2018

Author: Steve Down

Around 220 proteins have been linked to age in a proteomics study of healthy people of all ages, which could be used to predict morbidity and death as well as offer ways to slow the progression of aging.

Martian conundrum solved: Viking lander data reexamined for organics

Date: Aug 15, 2018

Author: Steve Down

The original GC/MS data sets from the Mars Viking landers in the 1970s have been reexamined to reveal the presence of Martian organic compounds, 40 years before they were detected by the Curiosity rover.

Elastic air: NMR of hydrogels

Date: Aug 15, 2018

Author: David Bradley

Superflexible aerogels can be used as highly efficient absorbents, thermal insulators, and pressure sensors. Now, a team from Japan with a little help from nuclear magnetic resonance (NMR) spectroscopy have developed super-elastic aerogels that can be processed easily and at low cost.

Advanced microscopy: Closing in on the liquid

Date: Aug 15, 2018

Author: David Bradley

 An international team has developed a new microscopy technique that allows them to visualize liquids at the nanoscale level - about 10 times greater resolution than possible with conventional transmission electron microscopy. The technique might greatly improve our understanding of the properties of liquids and liquid interfaces.

Boning up on evolution: X-raying fishy ancestors

Date: Aug 15, 2018

Author: David Bradley

An X-ray study has allowed European scientists to get an insider view of the fossilised skeletons of some our oldest vertebrate ancestors. Their findings might solve a 160-year-old mystery about how skeletons evolved in the first place.
