Published Scientific advance leads to a new tool in the fight against hackers
(via sciencedaily.com) A new form of security identification could soon see the light of day and help us protect our data from hackers and cybercriminals. Quantum mathematicians have solved a mathematical riddle that allows for a person's geographical location to be used as a personal ID that is secure against even the most advanced cyber attacks.
Published Exposure assessment for Deepwater Horizon oil spill: Health outcomes
(via sciencedaily.com) Mathematicians have developed statistical methods that lay the framework for the crucial first step of determining whether there are any linkages between exposures and health outcomes from the 2010 Deepwater Horizon oil spill, which is considered the largest marine oil spill in the history of the U.S.
Published Machine learning model could better measure baseball players' performance
(via sciencedaily.com) Researchers have developed a machine learning model that could better measure baseball players' and teams' short- and long-term performance, compared to existing statistical analysis methods for the sport. Drawing on recent advances in natural language processing and computer vision, their approach would completely change, and could enhance, the way the state of a game and a player's impact on the game is measured.
Published New technique offers faster security for non-volatile memory tech
(via sciencedaily.com) Researchers have developed a technique that leverages hardware and software to improve file system security for next-generation memory technologies called non-volatile memories (NVMs). The new encryption technique also permits faster performance than existing software security technologies.
Published Technology has the potential to change the patient-provider relationship
(via sciencedaily.com) As personal health records (AKA patient portals) allowing patients to see test results, medications and other health information gain in popularity, scientists studied cancer patients' and doctors' differing perceptions of this tool. Patients cited potential for personal health records to deepen their relationship with their healthcare provider and to allow them to be more understood. Physicians were interested in having more clinical information sharing to facilitate better patient care.
Published Study shows gaps in how STEM organizations collect demographic information
(via sciencedaily.com) Professional organizations in science, technology, engineering and mathematics (STEM) fields could more effectively collect data on underrepresented groups in their fields, according to a new survey. With more robust information, STEM organizations could better target efforts to recruit and retain a more diverse membership.
Published Lottery luck in the light of physics: Researchers present theory on the dynamics of many-particle systems
(via sciencedaily.com) Power functional theory is a new approach that makes it possible to describe precisely the dynamics of many-particle systems over time.
Published Speaking from the heart: Could your voice reveal your heart health?
(via sciencedaily.com) An artificial intelligence (AI)-based computer algorithm accurately predicted a person's likelihood of suffering heart problems related to clogged arteries based on voice recordings alone.
Published Single-photon source paves the way for practical quantum encryption
(via sciencedaily.com) Researchers describe new high-purity single-photon source that can operate at room temperature. The source is an important step toward practical applications of quantum technology, such as highly secure communication based on quantum key distribution (QKD).
Published Tiny, cheap solution for quantum-secure encryption
(via sciencedaily.com) Engineers propose a new kind of encryption to protect data in the age of quantum computers.
Published Qubits: Developing long-distance quantum telecommunications networks
(via sciencedaily.com) Computers, smartphones, GPS: quantum physics has enabled many technological advances. It is now opening up new fields of research in cryptography (the art of coding messages) with the aim of developing ultra-secure telecommunications networks. There is one obstacle, however: after a few hundred kilometers within an optical fiber, the photons that carry the qubits or 'quantum bits' (the information) disappear. They therefore need 'repeaters', a kind of 'relay', which are partly based on a quantum memory. By managing to store a qubit in a crystal (a 'memory') for 20 milliseconds, a team has now taken a major step towards the development of long-distance quantum telecommunications networks.
Published Tiny magnets could hold the secret to new quantum computers
(via sciencedaily.com) Scientists have discovered a type of magnetic behavior that could help enable magnetically based quantum devices.
Published Toward a quantum computer that calculates molecular energy
(via sciencedaily.com) Researchers have developed an algorithm that uses the most quantum bits to date to calculate ground state energy, the lowest-energy state in a quantum mechanical system. The discovery could make it easier to design new materials.
Published A first step towards quantum algorithms: Minimizing the guesswork of a quantum ensemble
(via sciencedaily.com) A quantum ensemble -- a set of quantum states with their corresponding probabilities -- is essential to the encoding of classical information for transmission over quantum channels. But receivers must be able to 'guess' the transmitted quantum state, incurring a cost called 'guesswork.' Recently, researchers have derived analytical solutions of the guesswork problem for when the ensemble is subject to a finite set of conditions. The results constitute a first step towards future algorithms for quantum software.
Published New insight into machine-learning error estimation
(via sciencedaily.com) Scientists are evaluating machine-learning models using transfer learning principles.
Published Double locked: Polymer hydrogels secure confidential information
(via sciencedaily.com) The development of highly secure but simple and inexpensive encryption technology for the prevention of data leaks and forgeries is decidedly challenging. A research team has now introduced a 'double lock' based on thermoresponsive polymer hydrogels that encrypts information so that it can only be read at a specific window in temperature and time.
Published New data analysis tool uncovers important COVID-19 clues
(via sciencedaily.com) A new data analysis tool has revealed the specific immune cell types associated with increased risk of death from COVID-19.
Published Using artificial intelligence to find anomalies hiding in massive datasets
(via sciencedaily.com) Researchers have developed a computationally efficient method that could be used to identify anomalies in the U.S. power grid in real time. The novel technique augments a special type of machine-learning model with a powerful graph structure, and does not require any labeled data to train.

(via sciencedaily.com) Researchers developed a technique that effectively protects computer programs' secret information from memory-timing side channel attacks, while enabling faster computation than other security schemes.
Published Navigation tools could be pointing drivers to the shortest route — but not the safest
(via sciencedaily.com) Time for a road trip. You punch the destination into your GPS and choose the suggested route. But is this shortest route the safest? Not necessarily, according to new findings.
