Cascading events led to 2018 Kīlauea volcanic eruption, providing clues for forecasting
The 2018 eruption of Kīlauea Volcano was one of the largest volcanic events in Hawai'i in 200 years. This eruption was triggered by a relatively small and rapid change at the volcano after a decade-long build-up of pressure in the upper parts of the volcano, according to a recent study published in Nature Communications by earth scientists from the University of Hawai'i at Mānoa and U.S. Geological Survey.

Ancient people relied on coastal environments to survive the Last Glacial Maximum
Excavations on the south coast of South Africa have uncovered evidence of human occupations from the end of the last ice age, approximately 35,000 years ago, through the complex transition to the modern time, known as the Holocene and adaptions that were key to our species ability to survive wide climate and environmental fluctuations.

Direct visualization of quantum dots reveals shape of quantum wave function
Trapping and controlling electrons in bilayer graphene quantum dots yields a promising platform for quantum information technologies. Researchers at UC Santa Cruz have now achieved the first direct visualization of quantum dots in bilayer graphene, revealing the shape of the quantum wave function of the trapped electrons.

UCF researcher zeroes in on critical point for improving superconductors
Developing a practical "room temperature" superconductor is a feat science has yet to achieve. However a UCF researcher and his colleagues are working to move this goal closer to realization by taking a closer look at what is happening in "strange" metals. The research was published recently in the journal Communications Physics - Nature.

CCNY researchers overcome barriers for bio-inspired solar energy harvesting materials
Inspired by nature, researchers at The City College of New York (CCNY) can demonstrate a synthetic strategy to stabilize bio-inspired solar energy harvesting materials. Their findings, published in the latest issue of Nature Chemistry, could be a significant breakthrough in functionalizing molecular assemblies for future solar energy conversion technologies.

Growing interest in Moon resources could cause tension, scientists find
An international team of scientists led by the Center for Astrophysics | Harvard & Smithsonian, has identified a problem with the growing interest in extractable resources on the moon: there aren't enough of them to go around. With no international policies or agreements to decide "who gets what from where," scientists believe tensions, overcrowding, and quick exhaustion of resources to be one possible future for moon mining projects. The paper published today in the Philosophical Transactions of the Royal Society A.

Understanding frustration could lead to better drugs
Atom-scale models of proteins that incorporate ligands, like drug molecules, shows a strong correlation between minimally frustrated binding sites and drug specificity. Such models could lead to better-designed drugs with fewer side effects.

Social bacteria build shelters using the physics of fingerprints
When starvation threatens, forest-dwelling Myxococcus xanthus bacteria work collectively to form fruiting bodies, spongy mushroom-like growths that promote survival. Princeton researchers have identified how these bacteria harness the same physical laws that lead to the whorls of a fingerprint to build the structures layer by layer.

A long distance connection: polar climate affects trade wind strength in tropics
The impact of sea surface temperature variations in the tropical Pacific on global climate has long been recognized. For instance, the episodic warming of the tropical Pacific during El Niņo events causes melt of sea ice in far-reaching parts of the Southern Ocean via its effect on the global atmospheric circulation. A new study, published this week in the journal Science Advances by an international team, demonstrates that the opposite pathway exists as well.

Gut-brain axis influences multiple sclerosis
A Basel-led international research team has discovered a connection between the intestinal flora and sites of inflammation in the central nervous system in multiple sclerosis. A specific class of immune cell plays a central role in this newly identified gut-brain axis. The discovery could pave the way for new treatments for MS that target the intestinal flora.

Predicting forces between oddly shaped nanoparticles
Materials scientists at Duke University have devised a simplified method for calculating the forces that cause nanoparticles to self-assemble. With this new model and graphical user interface, researchers will be able to make previously impossible predictions about how nanoparticles with a wide variety of shapes will interact with one another. The new method offers opportunities for rationally designing such particles for a wide range of applications from harnessing solar energy to driving catalytic reactions.

UCF researchers identify features that could make someone a virus super-spreader
In a study in Physics of Fluids, UCF researchers used computer-generated models to numerically simulate sneezes in different types of people and determine associations between people's physiological features and how far their sneeze droplets travel and linger in the air. They found that people's features, like a stopped-up nose or a full set of teeth, could increase their potential to spread viruses by affecting how far droplets travel when they sneeze.

Showing robots how to drive a just a few easy lessons
USC researchers have designed a system that lets robots autonomously learn complicated tasks from a very small number of demonstrations--even imperfect ones. While current state-of-art methods need at least 100 demonstrations to nail a specific task, this new method allows robots to learn from only a handful of demonstrations.

Researchers peer inside deadly pathogen's burglary kit
The bacterium that causes the tick-borne disease tularemia is a lean, mean infecting machine. It carries a relatively small genome, and a unique set of infectious tools, including a collection of chromosomal genes called 'the pathogenicity island.' Structural insights from Cryo-EM microscopy, appearing Nov. 19 in Molecular Cell, point to a way in which the bacterium's unique infectious machinery might be blocked.

Very hungry and angry, caterpillars head-butt to get what they want
When food is scarce, monarch butterfly caterpillars go from docile to domineering. The results look something like a combination of boxing and "bumper" cars. The less food, the more likely caterpillars were to try to head-butt each other out of the way to get their fill, lunging and knocking aside other caterpillars to ensure their own survival. And, they are most aggressive right before the final stages of their metamorphosis.

The very hungry, angry caterpillars
In the absence of milkweed--their favorite food--monarch butterfly caterpillars (Danaus plexippus) go from peaceful feeders to aggressive fighters. Researchers reporting in the journal iScience on November 19 observed that caterpillars with less access to food were more likely to lunge at others to knock them aside, and caterpillars were most aggressive during the final stages before metamorphosis.
