Can mammogram screening be more effective?
MIT economists have identified an important challenge in designing age-related guidelines for when to start breast cancer screenings: Women who start getting mammograms at age 40 may be healthier than the population of 40-year-old women as a whole, with a lower incidence of breast cancer at that age.
Support for the research was provided, in part, by the Laura and John Arnold Foundation, the National Institute on Aging, and the National Science Foundation.

Physicists quantum simulate a system in which fermions with multiple flavors behave like bosons
Quantum simulations show that boson-like behaviours, so-called bosonization, emerge from an ensemble of fermions in three-dimensional systems, despite that bosons and fermions are governed by distinct quantum statistics

University of Oregon researchers solve a Colorado River mystery
University of Oregon researchers have published two papers that provide new evidence that today's desert landscape of the Colorado River's lower valley was submerged roughly 5 million to 6 million years ago under shallow seas with strong, fluctuating tidal currents.

TGen identifies gene that could explain disparity in COVID-19 effects
TGen identified a genetic target that could help explain the tremendous variation in how sick those infected with COVID-19 become. Led by Nicholas Schork, Ph.D., Director of TGen's Quantitative Medicine and Systems Biology Division, researchers identified miR1307 by comparing the genetic elements of SARS-Cov-2 with seven other human coronaviruses, and the genomes of coronavirus strains known to infect bats, pigs, pangolins, ferrets, civets and chickens.

Astronomers detect possible radio emission from exoplanet
By monitoring the cosmos with a radio telescope array, a Cornell University-led international team of scientists has detected radio bursts emanating from the constellation Bo÷tes. The signal could be the first radio emission collected from a planet beyond our solar system.

Graduate student's BADASS code has astronomical benefits
An astro-statistics course UC Riverside graduate student Remington Sexton took three years ago taught him techniques that led him to develop free, open-source code benefiting astronomers everywhere. Called BADASS, the code is unique in that it provides a way for astronomers to fit the stellar motions of stars simultaneously with many other components, is written in a popular programming language, and is versatile enough to fit not just active galactic nuclei but also normal galaxies.

The DNA regions in our brain that contribute to make us human
With only 1% difference, the human and chimpanzee protein-coding genomes are remarkably similar. Understanding the biological features that make us human is part of a fascinating and intensely debated line of research. Researchers at the SIB Swiss Institute of Bioinformatics and the University of Lausanne have developed a new approach to pinpoint, for the first time, adaptive human-specific changes in the way genes are regulated in the brain.

RNA molecules are masters of their own destiny
A new paper suggests that RNA molecules are responsible for regulating their own formation through a feedback loop. Too few RNA molecules, and the cell initiates transcription to create more. Then, at a certain threshold, too many RNA molecules cause transcription to draw to a halt.

African American youth who receive positive messages about their racial group may perform better in school
Youth of color represent over half of the school-aged population (kindergarten through twelfth grade) in public schools in the United States. This creates a need for evidence-driven approaches that address the pervasive Black-White achievement gap. A new longitudinal study shows that African American youth who receive positive messages about their racial group in school achieved better school grades one to two years later.

Reversible superoxide-peroxide conversion drives high-capacity potassium-metal batte
Boosting the energy density is a universal topic for energy storage devices, especially for the low-price potassium-ion battery (KIB) technology, in which the limited specific capacities of cathode seriously hinder its development. Regarded as an attractive capacity-boosting strategy, triggering the O-related anionic redox activity has not been realized within sealed KIB system. Herein, the reversible superoxide/peroxide (KO2/K2O2) inter-conversion on a KOČ2-based cathode has been achieved in high-energy-density KIBs.

Urban land and aerosols amplify hazardous weather, steer storms toward cities

Accurate neural network computer vision without the 'black box'
New research by a team at Duke University offers clues to what goes on inside the minds of machines as they learn to see. Instead of attempting to account for a neural network's decision-making on a post hoc basis, their method shows how the network learns along the way, by revealing how much the network calls to mind different concepts to help decipher what it sees as the image travels through successive layers.

The phantom chorus: birdsong boosts human well-being in protected areas
Although many studies have found that humans benefit from spending time in nature, few studies have explored why. Researchers hid speakers that played recorded songs from a diverse group of birds on two sections of trails in Colorado. Hikers who heard the bird songs reported a greater sense of well-being than those who didn't. The survey results showed that both the sounds themselves and people's perception of biodiversity can increase humans' feelings of well-being.

Purdue researchers uncover blind spots at the intersection of AI and neuroscience
Is it possible to read a person's mind by analyzing the electric signals from the brain? The answer may be much more complex than most people think. Purdue University researchers - working at the intersection of artificial intelligence and neuroscience - say a prominent dataset used to try to answer this question is confounded, and therefore many eye-popping findings that were based on this dataset and received high-profile recognition are false after all.
