New mass spectrometry combo offers promise for tapping nature’s unknown chemical universe

Posted by 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 .

A brain scientist and a philosopher have resolved a 25-year-old wager on consciousness

Posted by in categories: computing, space

A case of wine was put on the line.

This is according to a report by Science Alert published on Tuesday.


A 25-year-old wager on the source of consciousness between German-American computational neuroscientist Christof Koch and Australian philosopher and cognitive scientist David Chalmers has come to a close with the first one admitting defeat.

Chinese ‘breakthrough’ allows making alloys with diverse metals at lower temperatures

Posted by 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.

Supercomputer reveals ninth Dedekind number, solving decades-old maths problem

Posted by in categories: mathematics, supercomputing

The first eight Dedekind numbers have been known to us, but the ninth one has remained elusive — until now.

Mathematics is a fascinating subject with many unsolved mysteries, such as the Riemann hypothesis, Fermat’s last theorem, Goldbach’s conjecture, and Dedekind’s numbers. The Dedekind numbers were first discovered in the 19th century by Richard Dedekind and have interested mathematicians ever since.

The first eight Dedekind numbers have been known to us, but the ninth one has remained elusive until now. KU Leuven and Paderborn University scientists have solved a decades-old mathematics problem by computing the ninth Dedekind number.

Researchers observe rubber-like elasticity in liquid glycerol for the first time

Posted by in categories: biological, engineering

Simple molecular liquids such as water or glycerol are of great importance for technical applications, in biology or even for understanding properties in the liquid state. Researchers at the Max Planck Institut für Struktur und Dynamik der Materie (MPSD) have now succeeded in observing liquid glycerol in a completely unexpected rubbery state.

In their article published in Proceedings of the National Academy of Sciences, the researchers report how they created rapidly expanding on the surface of the liquid in vacuum using a pulsed laser. However, the thin, micrometers-thick liquid envelope of the bubble did not behave like a viscous liquid dissipating deformation energy as expected, but like the elastic envelope of a rubber toy balloon, which can store and release elastic energy.

It is the first time an elasticity dominating the flow behavior in a Newtonian liquid like glycerol has been observed. Its existence is difficult to reconcile with common ideas about the interactions in liquid glycerol and motivates the search for more comprehensive descriptions. Surprisingly, the elasticity persists over such long timescales of several microseconds that it could be important for very rapid engineering applications such as micrometer-confined flows under . Yet, the question remains unsettled whether this behavior is a specific property of liquid glycerol, or rather a phenomenon that occurs in many molecular liquids under similar conditions but has not been observed so far.

New bioinspired robot flies, rolls, walks, and more

Posted by in categories: biotech/medical, robotics/AI

A newly created real-life Transformer is capable of reconfiguring its body to achieve eight distinct types of motion and can autonomously assess the environment it faces to choose the most effective combination of motions to maneuver.

The new , dubbed M4 (for Multi-Modal Mobility Morphobot) can roll on four wheels, turn its wheels into rotors and fly, stand on two wheels like a meerkat to peer over obstacles, “walk” by using its wheels like feet, use two rotors to help it roll up on two wheels, tumble, and more.
