Oxygen restriction helps fast-aging lab mice live longer
Posted by Paul Battista in categories: biotech/medical, chemistry, life extension
For the first time, researchers have shown that reduced oxygen intake, or “oxygen restriction,” is associated with longer lifespan in lab mice, highlighting its anti-aging potential. Robert Rogers of Massachusetts General Hospital in Boston, US, and colleagues present these findings in a study published May 23rd in the open access journal PLOS Biology.
Research efforts to extend healthy lifespan have identified a number of chemical compounds and other interventions that show promising effects in mammalian lab animals— for instance, the drug metformin or dietary restriction. Oxygen restriction has also been linked to longer lifespan in yeast, nematodes, and fruit flies. However, its effects in mammals have been unknown.
To explore the anti-aging potential of oxygen restriction in mammals, Rogers and colleagues conducted lab experiments with mice bred to age more quickly than other mice while showing classic signs of mammalian aging throughout their bodies. The researchers compared the lifespans of mice living at normal atmospheric oxygen levels (about 21%) to the lifespans of mice that, at 4 weeks of age, had been moved to a living environment with a lower proportion of oxygen (11%—similar to that experienced at an altitude of 5,000 meters).

New mass spectrometry combo offers promise for tapping nature’s unknown chemical universe
Posted by Shailesh Prasad in categories: biotech/medical, chemistry
The universe is awash in billions of possible chemicals. But even with a bevy of high-tech instruments, scientists have determined the chemical structures of just a small fraction of those compounds, maybe 1%.
Scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) are taking aim at the other 99%, creating new ways to learn more about a vast sea of unknown compounds. There may be cures for disease, new approaches for tackling climate change, or new chemical or biological threats lurking in the chemical universe.
The work is part of an initiative known as m/q, or “m over q” —shorthand for mass divided by charge, which signifies one of the ways that scientists measure chemical properties in the world of mass spectrometry.

Chinese ‘breakthrough’ allows making alloys with diverse metals at lower temperatures
Posted by Gemechu Taye in categories: innovation, materials
The simplicity of the approach stumped even reviewers of the journal Nature and needed further proof to be believed.
Researchers at the College of Chemistry and Molecular Sciences at Wuhan University in China have achieved a significant ‘breakthrough’ in materials science that allows alloys to be made from a diverse range of metals and at much lower temperatures than conventional methods, the South China Morning Post.
Since the Bronze Age, alloys have contributed to the advancement of our civilization. Modern-day applications of alloys involve creating and manufacturing high-entropy alloys (HEAs) composed of five or more metallic elements.
