Dynamics of molecular rotors in bulk superfluid helium
Molecules immersed in liquid helium can probe superfluidity since their electronic, vibrational and rotational dynamics can provide valuable cues about the superfluid at the nanoscale. In a new report in Science Advances, Alexander Milner and a team.....»»
Chemists create an emission molecular thermometer
Future technologies rely on phenomena that were previously considered the exclusive domain of theoretical physics or chemistry. For example, the approach to devices with high-density information storage arose when chemists discovered single-molecule.....»»
Light duty: Distinct molecular pathways control growth, flowering in plants
It's well known that plants have a fine-tuned ability to sense changes in the season by how much daylight they're exposed to, yet scientists observed more than a century ago that plants sometimes grow during one season and flower in another. Most res.....»»
The dynamics of deformable systems: Study unravels mathematical mystery of cable-like structures
Are our bodies solid or liquid? We all know the convention—that solids maintain their shapes, while liquids fill the containers they're in. But often in the real world, those lines are blurred. Imagine walking on a beach. Sometimes the sand gives w.....»»
Helium droplets capture double water structure
An elusive structure involving two water molecules, which had been predicted but never observed, has been isolated by RIKEN chemists. This finding could have implications for a wide range of fields ranging from astrochemistry to corrosion of metals......»»
Pioneering technique reveals new layer of human gene regulation
A technique can determine for the first time how frequently, and exactly where, a molecular event called "backtracking" occurs throughout the genetic material (genome) of any species, a new study shows......»»
Scientists develop new molecular system made from abundant element manganese for photooxidation
Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All.....»»
Hubble traces "string of pearls" star clusters in galaxy collisions
Contrary to what you might think, galaxy collisions do not destroy stars. In fact, the rough-and-tumble dynamics trigger new generations of stars and presumably accompanying planets......»»
Physicists capture first sounds of heat "sloshing" in a superfluid, revealing how heat can move like a wave
In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, moving back and forth somewhat like a sound wave that bounces from one end.....»»
Examining how molecular orbitals determine stability
Carboxylic acid dianions (fumarate, maleate, and succinate) play a role in coordination chemistry and, to some extent, also in the biochemistry of body cells. An HZB team at BESSY II has now analyzed their electronic structures using RIXS in combinat.....»»
Study finds corn genome can gang up on multiple pathogens at once
In a changing climate, corn growers must be ready for anything, including new and shifting disease dynamics. Because it's impossible to predict which damaging disease will pop up in a given year, corn with resistance to multiple diseases would be a.....»»
How molecular systems at the origin of life may have evolved: Rise of the nanomachines
By attaching molecules together, scientists at Université de Montréal think they've found how molecular systems at the origin of life evolved to create complex self-regulating functions......»»
Research team identifies new approach to tackling bacterial infections
Researchers at the Icahn School of Medicine at Mount Sinai have identified a new approach to controlling bacterial infections. The findings are described in Nature Structural & Molecular Biology......»»
Boston Dynamics’ Atlas tries out inventory work, gets better at lifting

Researchers discover key to molecular mystery of how plants respond to changing conditions
A team of researchers from the University of Massachusetts Amherst recently published a pioneering study that answers a central question in biology: How do organisms rally a wide range of cellular processes when they encounter a change—either inter.....»»
Decoding the molecular networks of early human development
New international research shines a light on the role of transcription factors during early embryonic development. Transcription factors are proteins that are critical for gene regulation. The study unveiled more than 1,000 protein–protein interact.....»»
Improving accuracy of molecular quantification in high throughput sequencing
A team at NDORMS has developed a new approach to significantly improve the accuracy of RNA sequencing. They have pinpointed the primary source of inaccurate quantification in both short and long-read RNA sequencing, and have introduced the concept of.....»»
Driverless vehicles covered five times more test miles in California in 2023
General Motors' Cruise unit and Google affiliate Waymo accounted for the bulk of the miles — 63 percent and 36 percent respectively — recorded without a safety driver, according to the state's department of motor vehicles......»»
Team discovers mechanism that protects tissue after faulty gene expression
A study at the University of Cologne's CECAD Cluster of Excellence in Aging Research has identified a protein complex that is activated by defects in the spliceosome, the molecular scissors that process genetic information. Future research could lead.....»»
Shifts in lake carbon dynamics on the Qingzang Plateau: From predominant carbon sources to emerging carbon sinks
A new study shows that annual carbon emissions from lakes in the Qingzang Plateau (QZP)—a vast elevated plateau at the intersection of Central, South, and East Asia—have declined, with some lakes shifting from carbon sources between 1970–2000 t.....»»
A type of plastic that can be shape-shifted using tempering
A team of molecular engineers have developed a type of plastic that can be shape-shifted using tempering. In their paper published in the journal Science the team, from the University of Chicago, with a colleagues from the US DEVCOM Army Research Lab.....»»
