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.....»»
Understanding the dynamics of snow cover in forests can help us predict flood risks
For more than six months a year, Quebec's boreal forest is covered in a thick blanket of snow. While this is essential for the balance of our ecosystems, for the people living downstream from forested watersheds the snow can be like a sword of Damocl.....»»
New research into pangolin genomics may aid in conservation efforts
A new paper in Molecular Biology and Evolution provides, for the first time, a comprehensive set of genomic resources for pangolins (sometimes known as scaly anteaters) that researchers believe will be integral for protecting these threatened mammals.....»»
How proteins roll the dice to determine bee sex
To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) including biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In th.....»»
Molecular knots, left and right: How molecules form knots
Helical molecules, similarly to a corkscrew, have a spiral shape that can be either left- or right-turning. Such "chiral molecules" can collectively organize (assemble) into large left- or right-handed twisted structures. These exhibit special optica.....»»
Google unveils stricter anti-spam rules for bulk email senders
To keep Gmail users’ inboxes “safer and more spam-free”, Google is introducing new requirements for bulk senders (of commercial email). “Last year we started requiring that emails sent to a Gmail address must have some form of.....»»
Electronic sensor the size of a single molecule a potential game-changer
Australian researchers have developed a molecular-sized, more efficient version of a widely used electronic sensor, in a breakthrough that could bring widespread benefits......»»
Simulations reveal the atomic-scale story of qubits
Researchers led by Giulia Galli at University of Chicago's Pritzker School of Molecular Engineering report a computational study that predicts the conditions to create specific spin defects in silicon carbide. Their findings, published online in Natu.....»»
Scientists observe interaction of components in tire rubber at the atomic scale
Scientists have observed the molecular motion of rubber components typically used in automobile tires—polybutadiene and carbon black—with the world's fastest time resolution......»»
Concave, umbrella-like metal complexes provide space for giant molecular rotors to operate in solid state
Solid materials are generally known to be rigid and unmoving, but scientists are turning this idea on its head by exploring ways to incorporate moving parts into solids. This can enable the development of exotic new materials such as amphidynamic cry.....»»
Intense lasers shine new light on the electron dynamics of liquids
An international team of researchers from the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) in Hamburg and ETH Zurich has now demonstrated that it is possible to probe electron dynamics in liquids using intense laser fields and.....»»
Elk hoof disease likely causes systemic changes
Elk treponeme-associated hoof disease, previously thought to be limited to deformations in elks' hooves, appears to create molecular changes throughout the animal's system, according to epigenetic research from Washington State University......»»

Examining the genesis of CRISPR"s molecular scissors
Genome engineering may be the future of medicine, but it relies on evolutionary advances made billions of years ago in primordial bacteria, the original masters of gene editing......»»
Study reveals how marine bacteria combat algae
Algae and bacteria are inseparable in ocean ecosystems, with bacteria playing a crucial role in regulating the growth and metabolism of algae. In addition to mutualism, bacteria have developed various molecular-based strategies to combat algae......»»
Chemists used machine learning and molecular modeling to identify potential anticancer drugs
RUDN University chemists and colleagues from China built several machine learning models and discovered a group of potential drugs that inhibit the enzyme responsible for uncontrolled cell division. The results were published in Biomedicines......»»
Successful optical biosensing using dual optical combs: High sensitivity and rapid detection of biomolecules
Bio-sensors are biomolecular sensors that leverage or mimic the sophisticated molecular recognition capabilities of living organisms. They find widespread applications in fields such as health care, food, and the environment......»»
The impact of solar eclipses on the structure and dynamics of Earth"s upper atmosphere
Solar eclipses can have a noticeable impact on the structure and dynamics of Earth's upper atmosphere—the ionosphere. This is primarily due to the sudden reduction in solar radiation reaching the Earth's atmosphere during the eclipse. Since the ion.....»»
Imaging the elusive skyrmion: Neutron tomography reveals their shapes and dynamics in bulk materials
Scientists at the National Institute of Standards and Technology (NIST) with colleagues elsewhere have employed neutron imaging and a reconstruction algorithm to reveal for the first time the 3D shapes and dynamics of very small tornado-like atomic m.....»»
Iron-based molecular switch improves reaction yield by modulating zeolite catalyst acidity
A molecular switch, or molecule that changes in response to varying environmental stimuli, has successfully modified the acidity of a zeolite catalyst to improve the yield of paraxylene from methanol in heterogeneous catalysis, or a reaction where th.....»»
