Quantum algorithm of the direct calculation of energy derivatives developed for molecular geometry optimization      (via sciencedaily.com) 

Researchers have successfully extended the quantum phase difference estimation algorithm, a general quantum algorithm for the direct calculations of energy gaps, to enable the direct calculation of energy differences between two different molecular geometries. This allows for the computation, based on the finite difference method, of energy derivatives with respect to nuclear coordinates in a single calculation.

How long can exotic nuclei survive at the edge of stability?      (via sciencedaily.com) 

A new study has measured how long it takes for several kinds of exotic nuclei to decay. The paper marks the first experimental result from the Facility for Rare Isotope Beams. It is just a small taste of what's to come at the facility, which will become 400 times more powerful over the coming years. Scientists used the facility to better understand nuclei, the collection of protons and neutrons found at the heart of atoms. Understanding these basic building blocks allows scientists to refine their best models and has applications in medicine, national security, and industry.

Material separates heavy water from ordinary water      (via sciencedaily.com) 

A research group has made a material that can effectively separate heavy water from normal water at room temperature. Until now, this process has been very difficult and energy intensive. The findings have implications for industrial -- and even biological -- processes that involve using different forms of the same molecule.

Unveiling the dimensionality of complex networks through hyperbolic geometry      (via sciencedaily.com)     Original source 

Reducing redundant information to find simplifying patterns in data sets and complex networks is a scientific challenge in many knowledge fields. Moreover, detecting the dimensionality of the data is still a hard-to-solve problem. A new article presents a method to infer the dimensionality of complex networks through the application of hyperbolic geometrics, which capture the complexity of relational structures of the real world in many diverse domains.

Music class in sync with higher math scores -- but only at higher-income schools      (via sciencedaily.com) 

Music and arts classes are often first on the chopping block when schools face tight budgets and pressure to achieve high scores on standardized tests. But it's precisely those classes that can increase student interest in school and even benefit their math achievement, according to a new study.

Physicists confirm hitch in proton structure      (via sciencedaily.com) 

A new precision measurement of the proton's electric polarizability has confirmed an unexplained bump in the data. The proton's electric polarizability shows how susceptible the proton is to deformation, or stretching, in an electric field. Like size or charge, the electric polarizability is a fundamental property of proton structure. The data bump was widely thought to be a fluke when seen in earlier measurements, so this new, more precise measurement confirms the presence of the anomaly and signals that an unknown facet of the strong force may be at work.

Our brains use quantum computation      (via sciencedaily.com) 

A team of scientists believe our brains could use quantum computation, after adapting an idea developed to prove the existence of quantum gravity to explore the human brain and its workings. The brain functions measured were also correlated to short-term memory performance and conscious awareness, suggesting quantum processes are also part of cognitive and conscious brain functions. Quantum brain processes could explain why we can still outperform supercomputers when it comes to unforeseen circumstances, decision making, or learning something new, while the discovery may also shed light on consciousness, the workings of which remain scientifically difficult to understand and explain.

Predicting risk of aneurysm rupture      (via sciencedaily.com) 

Predicting the rupture of aneurysms is crucial for medical prevention and treatment. As aspect ratio and size ratio increase and an aneurysm expands, the stress applied against the aneurysm walls and the time blood spends within it increase. This leads the probability of rupture to rise. Researchers develop a patient-specific mathematical model to examine what aneurysm parameters influence rupture risk prior to surgery. Computed tomography scans are fed into the model, which reconstructs the geometry and blood flow of the aneurysm. It then uses equations to describe the fluid flow, generating information about the blood vessel walls and blood flow patterns.

Study shows how math, science identity in students affects college, career outcomes      (via sciencedaily.com) 

Two researchers have published a study that asked students if they see themselves as a math or science person, then followed up with them several times in following years. Results showed those who said yes in ninth grade were much likelier to major in STEM subjects and work in related fields after college. The results show the importance of helping students have positive math and science experiences early and could be a way to help address equity gaps in STEM.
