Ionic crystal generates molecular ions upon positron irradiation
The positron, the antiparticle of the electron, has the same mass and charge as that of an electron but with the sign flipped for the charge. It is an attractive particle for scientists because the use of positrons has led to important insights and d.....»»
Researchers develop tiny nanoSABERs to aid battle against cancer
When Jedi Knights need to vanquish an enemy, they whip out their trusty lightsabers. In the future, thanks to Johns Hopkins researchers, doctors seeking to crush cancer may wield minuscule molecular nanoSABERs that allow them to look at tumors in way.....»»
Uncovering the secrets of spin-orbit optical Rabi oscillations
The Rabi oscillation has been proven to be one of the cornerstones of quantum mechanics, triggering substantial investigations in different disciplines including atomic and molecular physics, acoustics, and optics. Various important applications have.....»»
Aurora records reveal shortened solar cycle during Maunder minimum
Sunspots change in number depending on how much magnetic activity the solar dynamo generates. But there's not total chaos: These changes occur in a cycle, which lasts about 11 years on average. The sun also experiences extended periods of low activit.....»»

Research team clarifies molecular mechanisms of fungal infections
Fungal infections pose a threat to humans, animals and plants, and can have serious consequences. Together with colleagues from Frankfurt/Main and Aachen, a research team from Heinrich Heine University Düsseldorf (HHU) has now clarified an important.....»»
Researchers develop nonlinear optical crystals by unusual cationic substitution strategy
An ideal infrared (IR) nonlinear optical (NLO) crystal must have the advantages of a wide transmittance range, impressive laser-induced damage threshold (LIDT), sufficient birefringence index, bulk single-crystal form, and physicochemical stability......»»
How male mosquitoes compensate for having only one X chromosome
The research group of Dr. Claudia Keller Valsecchi (Institute of Molecular Biology, Mainz, Germany) and their collaborators have discovered the master regulator responsible for balancing the expression of X chromosome genes between males and females.....»»
Chiro-optical force observed at the nanoscale
A research group at the Institute for Molecular Science has successfully observed the left and right handedness of material structures at the nanoscale, by illuminating chiral gold nanostructures with circularly polarized light and detecting the opti.....»»
Paleontologists find first molecular evidence of ginger pigment molecules in fossil frogs
Paleontologists at University College Cork (UCC) have found the first molecular evidence of pheomelanin, the pigment that produces ginger coloration, in the fossil record......»»
Chemists create sensors to track potassium and sodium in cell organelles
Two studies by scientists at the University of Chicago have demonstrated a new way to look into the inner workings of cells—in particular, to track the flow of ions inside the many tiny organelles inside the cell......»»
Novel organic-inorganic semiconductor generates circularly polarized light
A research team under the direction of Prof. Dr. Felix Deschler at Heidelberg University's Institute for Physical Chemistry has developed a semiconductor that efficiently generates light and simultaneously gives that light a certain spin. According t.....»»
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.....»»
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.....»»
Using DNA as glue to hold nanostructures together and build ultra-strong colloidal crystal metamaterials
A team of chemical and biological engineers working with a group of nanotechnologists at Northwestern University in Illinois has developed a type of super-strong colloidal crystal metamaterial by gluing together metal nanostructures using strands of.....»»
Every iPhone screen has a barcode to prevent a manufacturing scam
Apple spent millions to add a barcode to iPhone displays in order to save being charged hundreds of millions by manufacturers claiming faulty screens that may not have been.Chinese display firms Lens Technology and Biel Crystal have been controversia.....»»
