Exploring molecular boundaries in DNA
It's important to be well organized. And this is especially true for the genome—the entirety of an organism's genetic information, also known as DNA. The genomic DNA is several meters long but has to fit inside the cell's nucleus, which has a diame.....»»
Conflict in Ukraine found to be causing significant greenhouse gas emissions
An international team of scientists examined the first 18 months since the beginning of the conflict in Ukraine, exploring its consequences beyond the loss of life, with the primary focus on military emissions. Their findings underscore limitations i.....»»
Important molecular pathway for control of aging discovered
One of the ways cells in different kinds of tissue communicate is by exchanging RNA molecules. In experiments with roundworms of the species Caenorhabditis elegans, researchers at the State University of Campinas (UNICAMP) in Brazil found that when t.....»»
Deciphering quantum enigmas: The role of nonlocal boxes in defining the boundaries of physical feasibility
A team of scientists from the University of Ottawa is offering insights into the mysteries of quantum entanglement. Their recent study, titled "Extending the known region of nonlocal boxes that collapse communication complexity" and published in Phys.....»»
Case study: The evolution of a series of participant-centered workshops

Microscopy method overcomes the traditional resolution limit for the fast co-tracking of molecules
Researchers at Ludwig Maximilian University (LMU) have developed an innovative method to simultaneously track rapid dynamic processes of multiple molecules at the molecular scale......»»
Into the belly of the rover: VIPER"s final science instrument installed
A team of engineers is preparing to integrate TRIDENT—short for The Regolith Ice Drill for Exploring New Terrain—into the belly of NASA's first robotic moon rover, VIPER (Volatiles Investigating Polar Exploration Rover)......»»
Exploring the chemistry behind love this Valentine"s Day
Chemistry in a relationship refers to the intense feelings of connection, passion, and romance that people share. This Valentine's Day, Dr. Alex Baker, a chemistry professor at the University of Warwick, explores the real chemistry behind chemistry......»»
Exploring the effect of ring closing on fluorescence of supramolecular polymers
In supramolecular chemistry, the self-assembly state of molecules plays a significant role in determining their tangible properties. Controlling the self-assembled state has garnered significant attention as it can be exploited to design materials wi.....»»
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.....»»
Here are the 20+ states exploring support for Apple’s digital IDs in Wallet feature
One of the most highly anticipated features announced at WWDC back in 2021 was support for storing IDs in the Apple Wallet application. Touted by Apple as the last step before you are “fully free of your physical wallet,” the feature is still onl.....»»
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.....»»
Assessment and strategies for sustainable food systems within planetary boundaries
Since the Green Revolution in the 1960s, intensive agricultural production practices have laid the foundation for food security. However, these measures are also accompanied by significant resource input and environmental impacts. Meeting the increas.....»»
Endangered by the 49th Parallel: How political boundaries inhibit effective conservation
Canada is wasting scarce resources conserving species that are not endangered elsewhere......»»
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.....»»
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......»»
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.....»»
