Laser reveals sound from supersonic molecules in near-space cold conditions

What happens when you hurl molecules faster than sound through a vacuum chamber nearly as cold as space itself? At the University of Missouri, researchers are finding out—and discovering new ways to detect molecules under extreme conditions.

The discovery could one day help chemists unravel the mysteries of astrochemistry, offering new clues about what the universe is made of, how stars and planets form and even where life originated.

In a recent study published in The Journal of Physical Chemistry A, Mizzou faculty member Arthur Suits and doctoral student Yanan Liu fired a laser at methane gas molecules moving faster than the in a at roughly −430°F, close to the temperature in parts of outer space.

Habitable planet potential increases in the outer galaxy

What can the galactic habitable zone (GHZ), galactic regions where complex life is hypothesized to be able to evolve, teach scientists about finding the correct stars that could have habitable planets?

This is what a recent study accepted for publication in Astronomy & Astrophysics hopes to address as an international team of researchers investigated a connection between the migration of stars, commonly called stellar migration, and what this could mean for finding habitable planets within our galaxy. This study has the potential to help scientists better understand the astrophysical parameters for finding habitable worlds beyond Earth and even life as we know it. The findings are published on the arXiv preprint server.

For the study, the researchers used a series of computer models to simulate how stellar migration could influence the location and parameters of the GHZ. The models included scenarios both with and without stellar migration to ascertain the statistical probabilities for terrestrial (rocky) planets forming around stars throughout the galaxy. The researchers also used a chemical evolution model to ascertain the formation and evolution of our galaxy, specifically regarding its thickness.

The Case for Life on Mars Just Got Stronger

“This finding by Perseverance 
is the closest we have ever come to discovering life on Mars,” said acting NASA administrator Sean Duffy in a statement. “The identification of a potential biosignature on the Red Planet is a groundbreaking discovery, and one that will advance our understanding of Mars.”

Perseverance did not discover fossilized microbes and it surely didn’t discover living ones. What it found was a rock streaked in a range of colors—red, green, purple, and blue—flecked with poppy-seed-like dots and decorated with what the Perseverance scientists compared to dull yellow leopard spots. That said a lot. As the rover’s instruments confirmed, the red is iron-rich mud, the purple is iron and phosphorous, the yellow and green are iron and sulfur. All of those elements serve as something of a chow line for hungry microbes.

The poppy seeds and leopard spots, meantime, resemble markings left behind by metabolizing microbes on Earth. When the rover trained its instruments on those features they detected two iron-rich minerals—vivianite and greigite. On Earth, vivianite is frequently found in peat bogs and around decaying organic matter—another item on the microbes’ menu. And both minerals can be produced by microbial life. Images of the rock with its distinctive features were beamed back to Earth by Perseverance, while X-ray and laser sensors analyzed the chemistry of the markings.

Pinning down protons in water—a basic science success story

The movement of protons through electrically charged water is one of the most fundamental processes in chemistry. It is evident in everything from eyesight to energy storage to rocket fuel—and scientists have known about it for more than 200 years.

But no one has ever seen it happen. Or precisely measured it on a microscopic scale.

Now, the Mark Johnson lab at Yale has—for the first time—set benchmarks for how long it takes protons to move through six charged . The discovery, made possible with a highly customized mass spectrometer that has taken years to refine, could have far-reaching applications for researchers in years to come.

Newly developed organic compounds can serve as highly sensitive oxygen sensors

Researchers at Kaunas University of Technology (KTU), Lithuania, have developed new organic compounds that act as highly sensitive oxygen sensors. These sensors can accurately detect even the slightest amounts of oxygen in the environment—information that is crucial in situations where oxygen concentration can determine the success of a process or even a person’s life.

The sensors can be applied in medicine; for example, in diagnosing tumor hypoxia, a condition in which there is almost no oxygen around a tumor; in the food industry, to check whether packaging has lost its seal; and in biotechnology, to precisely monitor cell cultivation processes.

Moreover, their performance can be observed with the naked eye, while their record-high sensitivity ensures rapid and reliable detection. The study is published in the journal Sensors and Actuators B: Chemical.

Clocks created from random events can probe ‘quantumness’ of universe

A newly discovered set of mathematical equations describes how to turn any sequence of random events into a clock, scientists at King’s College London reveal. The paper is published in the journal Physical Review X.

The researchers suggest that these formulas could help to understand how cells in our bodies measure time and to detect the effects of quantum mechanics in the wider world.

Studying these timekeeping processes could have far-reaching implications, helping us to understand proteins with rhythmic movements which malfunction in motor neuron disease or chemical receptors that cells use to detect harmful toxins.

From noise to power: A symmetric ratchet motor discovery

Vibrations are everywhere—from the hum of machinery to the rumble of transport systems. Usually, these random motions are wasted and dissipated without producing any usable work.

Recently, scientists have been fascinated by “ratchet systems,” which are that rectify chaotic vibrations into directional motion. In biology, molecular motors achieve this feat within living cells to drive the essential processes by converting random molecular collisions into purposeful motions. However, at a large scale, these ratchet systems have always relied on built-in asymmetry, such as gears or uneven surfaces.

Moving beyond this reliance on asymmetry, a team of researchers led by Ms. Miku Hatatani, a Ph.D. student at the Graduate School of Science and Engineering, along with Mr. Junpei Oguni, graduate school alumnus at the Graduate School of Science and Engineering, Professor Daigo Yamamoto and Professor Akihisa Shioi from the Department of Chemical Engineering and Materials Science at Doshisha University, demonstrate the world’s first symmetric ratchet motor.

Chemists Create Next-Gen Rocket Fuel Compound That Packs 150% More Energy

Chemists at the University at Albany have developed a high-energy compound that could transform rocket fuel and make space travel more efficient. When ignited, this compound produces significantly more energy per unit of weight and volume than current propellants.

For rockets, this means that less fuel would be needed to achieve the same mission duration or payload capacity, leaving more space for essential equipment and supplies. The research was published in the Journal of the American Chemical Society.

“In rocket ships, space is at a premium,” said Assistant Professor of Chemistry Michael Yeung, whose lab led the work. “Every inch must be packed efficiently, and everything onboard needs to be as light as possible. Creating more efficient fuel using our new compound would mean less space is needed for fuel storage, freeing up room for equipment, including instruments used for research. On the return voyage, this could mean more space is available to bring samples home.”
