Published Contact-tracing apps could improve vaccination strategies
(via sciencedaily.com) Mathematical modeling of disease spread suggests that herd immunity could be achieved with fewer vaccine doses by using Bluetooth-based contact-tracing apps to identify people who have more exposure to others -- and targeting them for vaccination.
Published A statistical fix for archaeology's dating problem
(via sciencedaily.com) Archaeologists have long had a dating problem. The radiocarbon analysis typically used to reconstruct past human demographic changes relies on a method easily skewed by radiocarbon calibration curves and measurement uncertainty. And there's never been a statistical fix that works -- until now.
Published Statistics say large pandemics are more likely than we thought
(via sciencedaily.com) The COVID-19 pandemic may be the deadliest viral outbreak the world has seen in more than a century. But statistically, such extreme events aren't as rare as we may think, asserts a new analysis of novel disease outbreaks over the past 400 years. A newly assembled record of past outbreaks was used to estimate the probability of a pandemic with similar impact to COVID-19 is about 2 percent in any year. And that probability is growing.
Published Protecting Earth from space storms
(via sciencedaily.com) A major space weather event could have a catastrophic impact on Earth, disabling communications and electrical systems. Researchers are using the Frontera supercomputer to develop new geomagnetic forecasting methods and improve the Geospace Model used by NOAA for operational purposes. They hope to increase the lead time for space weather events from 30 minutes to 1-3 days, localize space weather forecasts, and provide uncertainty estimates.
Published Solving solar puzzle could help save Earth from planet-wide blackouts
(via sciencedaily.com) Understanding the Sun's magnetic dynamo could help predict solar weather, such as potentially dangerous geothermal storms, solar flares and sunspots. Mathematicians have proposed a new model of the Sun that matches observed data.
Published Unravelling the knotty problem of the Sun's activity
(via sciencedaily.com) A new approach to analysing the development of magnetic tangles on the Sun has led to a breakthrough in a longstanding debate about how solar energy is injected into the solar atmosphere before being released into space, causing space weather events. The first direct evidence that field lines become knotted before they emerge at the visible surface of the Sun has implications for our ability to predict the behavior of active regions and the nature of the solar interior.
Published New framework applies machine learning to atomistic modeling
(via sciencedaily.com) A new method could lead to more accurate predictions of how new materials behave at the atomic scale.
Published Novel method predicts if COVID-19 clinical trials will fail or succeed
(via sciencedaily.com) Researchers have modeled COVID-19 completion versus cessation in clinical trials using machine learning algorithms and ensemble learning.
Published Cancer: Information theory to fight resistance to treatments
(via sciencedaily.com) A major challenge in cancer therapy is the adaptive response of cancer cells to targeted therapies. Although this adaptive response is theoretically reversible, such a reversal is hampered by numerous molecular mechanisms that allow the cancer cells to adapt to the treatment. A team has used information theory, in order to objectify in vivo the molecular regulations at play in the mechanisms of the adaptive response and their modulation by a therapeutic combination.
Published Lightning impacts edge of space in ways not previously observed
(via sciencedaily.com) A team of researchers working with data collected by an Incoherent Scatter Radar (ISR) have examined the simultaneous impacts of thunderstorms and solar flares on the ionospheric D-region (often referred to as the edge of space).
Published Boundary of heliosphere mapped
(via sciencedaily.com) For the first time, the boundary of the heliosphere has been mapped, giving scientists a better understanding of how solar and interstellar winds interact.
Published 'Surfing' particles: Physicists solve a mystery surrounding aurora borealis
(via sciencedaily.com) The spectacularly colorful aurora borealis -- or northern lights -- that fills the sky in high-latitude regions has fascinated people for thousands of years. Now, a team of scientists has resolved one of the final mysteries surrounding its origin.
Published Which way does the solar wind blow?
(via sciencedaily.com) High performance computers are central to the quest to understand the sun's behavior and its role in space weather events. Scientists are using the Frontera supercomputer to improve the state-of-the-art in space weather forecasting. Researchers described the role of backstreaming pickup ions in the acceleration of charged particles in the universe, which play an important role in space weather.
Published Researchers explore ways to detect 'deep fakes' in geography
(via sciencedaily.com) It may only be a matter of time until the growing problem of 'deep fakes' converges with geographical information science (GIS). A research team are doing what they can to get ahead of the problem.
Published Understanding of invisible but mighty particles in Earth's radiation belts
(via sciencedaily.com) Tiny charged electrons and protons which can damage satellites and alter the ozone have revealed some of their mysteries to scientists.
Published Scientific software - Quality not always good
(via sciencedaily.com) Computational tools are indispensable in almost all scientific disciplines. Especially in cases where large amounts of research data are generated and need to be quickly processed, reliable, carefully developed software is crucial for analyzing and correctly interpreting such data. Nevertheless, scientific software can have quality quality deficiencies. To evaluate software quality in an automated way, computer scientists have designed the SoftWipe tool.
Published Accurate evaluation of CRISPR genome editing
(via sciencedaily.com) Researchers have developed a new software tool to detect, evaluate and quantify off-target editing activity, including adverse translocation events that can cause cancer. The software is based on input taken from a standard measurement assay, involving multiplexed PCR amplification and Next-Generation Sequencing (NGS).
Published Smartphone breath alcohol testing devices vary widely in accuracy
(via sciencedaily.com) The latest generation of personal alcohol breath testing devices pair with smartphones. While some of these devices were found to be relatively accurate, others may mislead users into thinking that they are fit to drive, according to a new study.
Published Quantum drum duet measured
(via sciencedaily.com) Like conductors of a spooky symphony, researchers have 'entangled' two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks.
Published Airports could generate enough solar energy to power a city
(via sciencedaily.com) New research shows placing solar panels on the roofs of Australian airport buildings could be an efficient step towards net zero emissions.
