Chemists develop new sustainable reaction for creating unique molecular building blocks
Polymers can be thought of like trains: Just as a train is composed of multiple cars, polymers are made up of multiple monomers, and the couplings between the train cars are similar to the chemical bonds that link monomers together. While polymers ha.....»»
Ancient grains of dust from space can be found on Earth—and provide clues about the life cycle of stars
In space, there are clouds that contain gas and dust ejected from stars. Our solar system was formed 4.6 billion years ago from such a molecular cloud. Most of these dust grains were destroyed during solar system formation. However, a very small amou.....»»
Astronomers discover two new super-Earths orbiting nearby stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected two new super-Earth exoplanets orbiting nearby M-dwarf stars. The newfound exoplanets, designated TOI-6002 b and TOI-5713 b, are two times la.....»»
Breakthrough in molecular control: New bioinspired double helix with switchable chirality
The deoxyribonucleic acid or DNA, the molecular system that carries the genetic information of living organisms, can transcribe and amplify information using its two helical strands. Creating such artificial molecular systems that match or surpass DN.....»»
New technology protects crops by testing the air for the DNA of plant diseases
Plant infections can now be detected in our crops before they're even visible......»»
First full 2-D spectral image of aurora borealis from a hyperspectral camera
Auroras are natural luminous phenomena caused by the interaction of electrons falling from the sky and the upper atmosphere. Most of the observed light consists of emission lines of neutral or ionized nitrogen and oxygen atoms and molecular emission.....»»

New technique detects THC in saliva in minutes with minimal sample
With just a few drops of saliva and in a few minutes the presence of THC can be detected thanks to a technique developed by the universities of Cordoba and Valencia, making it possible to accelerate the analysis process and to use very small samples.....»»
New technique streamlines synthesis of heavy element compounds
Molecular compounds with heavy elements, like americium, curium and others can now be synthesized in a streamlined and efficient way thanks to a new technique developed by Lawrence Livermore National Laboratory (LLNL) researchers......»»
Sensing ultraviolet light with the help of molecular switches
The old saying "the dose makes the poison" also holds true for ultraviolet (UV) light. While UV light is essential for vitamin D production, it is also important in phototherapy, several industrial processes, and plant growth. It also has harmful eff.....»»
Early riser: The sun is already starting its next solar cycle—despite being halfway through its current one
The first rumblings of the sun's next 11-year solar cycle have been detected in sound waves inside our home star—even though it is only halfway through its current one......»»
Scientists uncover the molecular mechanism behind pineapple peel coloration
Pineapple peel coloration, especially the red hue, significantly enhances its commercial and aesthetic value. However, the genetic mechanisms driving this trait are not well understood, complicating breeding efforts for red-skinned varieties......»»
Observations detect a nearby hypervelocity stellar/substellar object
Using the Keck II telescope, astronomers have detected an object that may be a brown dwarf or a low-mass star, exhibiting a very high radial velocity. The object, designated CWISE J124909.08+362116.0 is located some 400 light years away. The finding.....»»
Material with molecular trapdoor holds promise for highly selective gas adsorption
