UMBC team reveals possibilities of new one-atom-thick materials
New 2D materials have the potential to transform technologies, but they're expensive and difficult to synthesize. Researchers at UMBC used computer modeling to predict the properties of 2D materials that haven't yet been made in real life. These highly-accurate predictions show the possibility of materials whose properties could be "tuned" to make them more efficient than existing materials in particular applications. A separate paper demonstrated a way to integrate these materials into real electronic devices.

Fractured bedrock in forests is overlooked source of natural CO2
According to a study led by The University of Texas at Austin, CO2 is being produced deep underground in bedrock fractures. This source could account for up to 29% of the daily average CO2 emitted by the land.

The farthest galaxy in the universe
A team of astronomers used the Keck I telescope to measure the distance to an ancient galaxy. They deduced the target galaxy GN-z11 is not only the oldest galaxy but also the most distant. It's so distant it defines the very boundary of the observable universe itself. The team hopes this study can shed light on a period of cosmological history when the universe was only a few hundred million years old.

Massive underground instrument finds final secret of our sun's fusion
The Borexino detector, a hyper-sensitive instrument deep underground in Italy, has finally succeeded at the nearly impossible task of detecting CNO neutrinos from our sun's core. These little-known particles reveal the last missing detail of the fusion cycle powering our sun and other stars, and could answer still-outstanding questions about the sun's composition.

'Magic' angle graphene and the creation of unexpected topological quantum states
Electrons inhabit a strange and topsy-turvy world. These infinitesimally small particles have never ceased to amaze and mystify despite the more than a century that scientists have studied them. Now, in an even more amazing twist, physicists have discovered that, under certain conditions, interacting electrons can create what are called "topological quantum states." This finding, recently published in the journal Nature, has implications for many technological fields of study, especially information technology.

Ancient DNA continues to rewrite corn's 9,000-year society-shaping history
In the Dec. 14 issue of the journal the Proceedings of the National Academy of Sciences, international team of scientists report the fully sequenced genomes of three roughly 2,000-year-old cobs from the El Gigante rock shelter in Honduras. Analysis of the three genomes reveals that these millennia-old varieties of Central American corn had South American ancestry and adds a new chapter in an emerging complex story of corn's domestication history.

How computer simulation will accelerate development of human-interactive "smart robots"
Lehigh University's Jeff Trinkle, along with colleagues at other institutions, has co-authored a "Perspective" paper called "On the use of simulation in robotics: Opportunities, challenges, and suggestions for moving forward" that appears in the latest issue of PNAS arguing that "...well-validated computer simulation can provide a virtual proving ground that in many cases is instrumental in understanding safely, faster, at lower costs, and more thoroughly how the robots of the future should be designed and controlled for safe operation and improved performance."

Mystery solved with math: cytoplasmic traffic jam disrupts sleep-wake cycles?
KAIST mathematicians and their collaborators at Florida State University have identified the principle of how aging and diseases like dementia and obesity cause sleep disorders. A combination of mathematical modelling and experiments demonstrated that the cytoplasmic congestion caused by aging, dementia, and/or obesity disrupts the circadian rhythms in the human body and leads to irregular sleep-wake cycles. This finding suggests new treatment strategies for addressing unstable sleep-wake cycles.

How AI could make therapeutic decision-making for breast cancer more accurate, affordable
Deep learning-enabled breast cancer technology could make breast cancer therapy decisions more accurate, affordable and accessible. For newly diagnosed breast cancer, estrogen receptor status (ERS) is a key molecular marker used for prognosis and treatment decisions. This is an expensive, time-consuming process. Here we show that machine learning can determine molecular marker status. Our approach could augment clinicians' capabilities in cancer prognosis and theragnosis by harnessing biological signals imperceptible to the human eye.

Restorative justice preferred among the Enga in Papua New Guinea
Most large-scale populations employ a punitive judicial system. Advocates have long called for a more restorative justice system that repairs harm to victims and reintegrates wrongdoers into society. A study analyzing 10 years of court cases of the Enga of Papua New Guinea show that they overwhelmingly emphasize restorative justice, allowing both sides and community members share their story, the community assists paying compensation to the victim, and supports reintegrating the offender back into society.

Exoplanet around distant star resembles reputed 'Planet Nine' in our solar system
Astronomers think planets can exist in orbits far from their star, and propose a two-step process: interactions with the star or inner planets kick it out of the inner system, and then a passing star stabilizes the orbit to keep it bound. Such a scenario could explain the hypothesized "Planet Nine" in our solar system. Astronomers has now confirmed that one binary star system, HD 106906, has a planet in a bound, highly eccentric orbit.

What caused the ice ages? Tiny ocean fossils offer key evidence
Since the discovery that atmospheric carbon dioxide (CO2) concentrations were lower during past ice ages, the cause has been a mystery. Now, fossils of ocean algae reveal that a weakening in upwelling in the Antarctic Ocean kept more CO2 in the deep ocean during the ice ages. This brings scientists closer to a complete explanation for the glacial cycle and suggests that upwelling will strengthen under anthropogenic global warming, altering global climate and ocean ecosystems.
