Collisions with electrons cool molecular ions
A lone molecule free in cold space will cool by slowing down its rotation—it will spontaneously lose its rotational energy in quantum transitions, typically only once in many seconds. This process can be accelerated, slowed down, or even inverted b.....»»
XREAL (formerly Nreal) Air AR glasses are so cool but need some serious work
The XREAL (formerly Nreal) AR glasses provide an immersive external monitor experience, but the augmented reality and 3D offerings are disappointing. When I was a kid, I was given a Virtual Boy — Nintendo’s very ‘90s predecess.....»»
Samsung’s First Galaxy S24 Update Addresses Display, Camera
Here’s a cool thing to know about the company that makes your phone – sometimes they listen. Samsung announced a first update for the Galaxy S24 Series today that was created quickly in response to user feedback. It touches on complaints.....»»
Case study: The evolution of a series of participant-centered workshops
Ludmila Tyler, senior lecturer in the biochemistry and molecular biology (BMB) department, is co-first author of a paper in the journal Biochemistry and Molecular Biology Education that reflects on the lessons learned from the first full year of Incl.....»»
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......»»
Watch SpaceX stack its Starship rocket in super-quick time
SpaceX has shared a cool video showing its robotic Mechazilla launch tower stacking its Starship rocket ahead of the vehicle's third test flight......»»
A century of reforestation helped keep the eastern US cool, study finds
Widespread 20th-century reforestation in the eastern United States helped counter rising temperatures due to climate change, according to new research. The authors highlight the potential of forests as regional climate adaptation tools, which are nee.....»»
Researchers solve a foundational problem in transmitting quantum information
Future quantum electronics will differ substantially from conventional electronics. Whereas memory in the latter is stored as binary digits, the former is stored as qubits, which can take many forms, such as entrapped electrons in nanostructures know.....»»
Overcoming fine process limits with linker ion affinity
A research team has employed linker ions to pioneer a three-dimensional microprinting technology applicable to inorganic substances and other various materials. The work is published in the journal Nature Communications......»»
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.....»»
How semiconductor defects could boost quantum technology
In diamonds (and other semiconducting materials), defects are a quantum sensor's best friend. That's because defects, essentially a jostled arrangement of atoms, sometimes contain electrons with an angular momentum, or spin, that can store and proces.....»»
Apple Maps offers an inside look at Allegiant Stadium ahead of Super Bowl LVIII
Ahead of Super Bowl LVIII kicking off in a few hours, you can head to the Apple Maps app and get a very cool inside look at Allegiant Stadium in Las Vegas, Nevada. Apple has overhauled the Apple Maps imagery ahead of today’s Chiefs vs 49ers game, w.....»»
Hubble detects celestial "string of pearls" star clusters in galaxy collisions
When spectacular cosmic events such as galaxy collisions occur, it sets off a reaction to form new stars, and possibly new planets that otherwise would not have formed. The gravitational pull that forces the collisions between these galaxies creates.....»»
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......»»
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.....»»
Quantum materials: A new state of matter with chiral properties
An international research group has discovered a new state of matter characterized by the existence of a quantum phenomenon called chiral current. These currents are generated on an atomic scale by a cooperative movement of electrons, unlike conventi.....»»
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......»»
