Hear that? Mizzou researchers are ‘listening’ to molecules in supersonic 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, Mizzou faculty member Arthur Suits and doctoral student Yanan Liu fired a laser at methane gas molecules moving faster than the speed of sound in a vacuum chamber roughly negative 430 degrees Fahrenheit, close to ...

Scientists uncover key stabilizing role of small molecules

For decades, amino acids have been added to medical formulations like insulin as stabilizers: these small molecules keep proteins (i.e. larger particles) from interacting in undesirable ways. And for decades, scientists have known that this works – but not why. Now, an international team of scientists, led by the Supramolecular Nano-Materials and Interfaces Laboratory in EPFL’s School of Engineering, has finally explained the ‘why’ – and in the process, unearthed a fundamental stabilizing effect ...

Human activities linked to declines of big seeds

Seeds in Madagascar’s forests are getting smaller, and new research published in Ecology Letters suggests that human activities are playing a role in this shift. Researchers from the German Centre for Integrative Biodiversity Research (iDiv) and Leipzig University combined data from more than 2,800 plant species, 48 living and 15 extinct fruit-eating animals (frugivores) – including birds and lemurs. The results show that both past human-driven frugivore extinctions and current human pressures are shaping seed size across the island. The researchers found that increased human footprint (a cumulative index of human pressure) is associated ...

Turbulence with a twist

Turbulence is everywhere, yet much about the nature of turbulence remains unknown. During the last decade, physicists have discovered how fluids in a pipe or similar geometry transition from a smooth, laminar state to a turbulent state as their speed increases. Surprisingly, in the newly emerging consensus, the process could be understood using statistical mechanics, not fluid mechanics, and was mathematically equivalent to the way in which water percolates down through a coffee filter. In a new twist, UC San Diego researchers Guru K. Jayasingh and Nigel Goldenfeld ...

Revealed: The long legacy of human-driven ant decline in Fiji

A new study of ants in Fiji – involving genomic sequencing of over 4,000 ant specimens from museum collections – shows that most native species have been in decline since humans first arrived in the archipelago 3,000 years ago. Meanwhile, recently introduced ant species have expanded. The findings underscore how human activity has and continues to reshape fragile island ecosystems. Insects, which make up much of Earth’s biodiversity, provide crucial ecosystem services, including pollination, soil ...

Inadequate regulatory protections for consumer genetic data privacy in US

In a Policy Forum, Natalie Ram and colleagues discuss the concerning gaps in robust regulatory protection on direct-to-consumer genetic data and biospecimens. After declaring bankruptcy in March 2025, the direct-to-consumer (DTC) genetic testing company, 23andMe, sold the genetic data of over 15 million people worldwide to a nonprofit founded by 23andMe’s own CEO. Although the nature of the sale meant the data remained under familiar leadership, it was controversial and highlighted critical gaps in legal ...

Scientist, advocate and entrepreneur Lucy Shapiro to receive Lasker-Koshland special achievement award

In 1959, Lucy Shapiro, a freshman honors student at Brooklyn College majoring in arts and literature, had signed up for a course in inorganic chemistry on a lark. It didn’t interest her, and she stopped attending. But at the end of the term, having failed to officially drop the class, she was notified she had to take the final exam. “It was a multiple-choice test, so I just circled all the B's,” recalled Shapiro, PhD, professor emerita of developmental biology and director of Stanford Medicine’s Beckman Center recalled. She received a D. Three years later, the budding artist met physical ...

Zoology: Octopuses put their best arm forward for every task

Octopuses can use any of their arms to perform tasks, but tend to use a particular arm, or arms, for specific tasks. This finding, presented in a paper in Scientific Reports, reveals more about the complex behaviour these animals display. Octopus arms are complex structures consisting of four separate muscle groups — transverse, longitudinal, oblique, and circular — around a central nerve. These four muscle groups allow octopus arms to deform in a wide variety of ways to perform a range of actions used for various behaviours, from hunting and moving, to self-defence. However, little is known about how wild ...

New research reveals wild octopus arms in action

Octopuses are among the most neurologically complex invertebrates, famed for their extraordinary dexterity. Their eight arms allow them to capture hidden prey, communicate, explore, and even mate across varied habitats. Although octopus arms rank among some of the most flexible structures in nature, their full range of movement has rarely been studied in the wild – especially in a range of underwater habitats. A new study by Florida Atlantic University’s Charles E. Schmidt College of Science, in collaboration with researchers from the Marine Biological ...

How many ways can an octopus flex its supple arms? Now we know

By David Chandler WOODS HOLE, Mass. -- Octopus arms are one of the most flexible structures known in all of the biological world. Their agility is so extraordinary that robotics researchers want to learn the secrets behind their movements, hoping to apply some of the same principles. They envision soft, flexible robotic appendages that, like the highly tactile octopus arms, can search and carry out tasks through tight and narrow openings, such as delivering life-saving food and water to people trapped in the rubble of collapsed buildings. Now, researchers from the Marine Biological Laboratory (MBL) in Woods Hole and Florida Atlantic University (FAU) ...

The metals reveal: The Bronze Age was more connected than we previously thought

In the Bronze Age, the so-called Nuraghe culture flourished in Sardinia. A culture that is known for tower-like stone constructions, nuraghers, and for the small bronze figures, bronzetti, which often depict warriors, gods and animals. These figures have fascinated scientists, but their exact metallic origins have been unknown. To find out where the copper in these figures came from, the research team used a new scientific method called a multi-proxy approach (a combination of different chemical analyses). Here, they compared isotopes of copper, tin, lead and a rarer isotope called ...

Researchers revive the pinhole camera for next-gen infrared imaging

WASHINGTON — Researchers have used the centuries-old idea of pinhole imaging to create a high-performance mid-infrared imaging system without lenses. The new camera can capture extremely clear pictures over a large range of distances and in low light, making it useful for situations that are challenging for traditional cameras. “Many useful signals are in the mid-infrared, such as heat and molecular fingerprints, but cameras working at these wavelengths are often noisy, expensive or require cooling,” said research team leader Heping Zeng from East China Normal University. “Moreover, traditional lens-based setups have ...

New evidence of long-distance travelers in Seddin during the Bronze Age

Recent research suggests that many of the Bronze Age people buried in Seddin, Germany, were not locals but came from outside the region. While archaeologists had previously uncovered artefacts from other parts of Europe around Seddin, this new study reveals that people themselves travelled and settled in Seddin. This is the first bioarchaeological investigation on human skeletal remains from the Seddin area. While studying archaeological artefacts can reveal trade and exchange between different areas, it cannot determine whether this was accompanied by human travel. This new study sheds light on how people ...

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 mechanical systems 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 ...
