The extent to which Brazilian soy production and trade contribute to climate change depends largely on the location where soybeans are grown, according to a new study. In some municipalities, carbon dioxide emissions resulting from the export of soybean and derivatives are more than 200 times higher than in others.

High-temperature superconductors have the potential to revolutionize today's technologies. 'Higgs spectroscopy' could bring about a watershed as it reveals the dynamics of paired electrons in superconductors. Remarkably, the dynamics also reveal typical precursors of superconductivity even above the critical temperature at which the materials investigated attain superconductivity.

Researchers analyzed patient data from 10 countries. The team found a correlation between low vitamin D levels and hyperactive immune systems. Vitamin D strengths innate immunity and prevents overactive immune responses. The finding could explain several mysteries, including why children are unlikely to die from COVID-19.

The geologic record is exactly that: a record. The strata of rock tell scientists about past environments, much like pages in an encyclopedia. Except this reference book has more pages missing than it has remaining. So geologists are tasked not only with understanding what is there, but also with figuring out what's not, and where it went.

People with body integrity dysphoria (BID) often feel as though one of their healthy limbs isn't meant to be a part of their bodies. They may act as though the limb is missing or even seek its amputation 'to feel complete.' Now, researchers have found that these feelings that a limb doesn't belong are mirrored in the brains of people with this condition.

For the first time, researchers have succeeded in creating strong coupling between quantum systems over a greater distance. They accomplished this with a novel method in which a laser loop connects the systems, enabling nearly lossless exchange of information and strong interaction between them. The physicists reported that the new method opens up new possibilities in quantum networks and quantum sensor technology.

In physics, thermalization, or the trend of sub-systems within a whole to gain a common temperature, is typically the norm. There are situations, however, where thermalization is slowed down or virtually suppressed; examples are when considering the dynamics of electron and nuclear spins in solids. Understanding why this happens and how it can be controlled is presently at the center of a broad effort, particularly for applications in the emerging field of quantum information technologies.

NASA's Hubble Space Telescope and the ground-based Gemini Observatory in Hawaii have teamed up with the Juno spacecraft to probe the mightiest storms in the solar system, taking place more than 500 million miles away on the giant planet Jupiter.

Olanzapine, a generic drug used to treat nervous, emotional and mental conditions, also may help patients with advanced cancer successfully manage nausea and vomiting unrelated to chemotherapy.

Thinning the Sierra Nevada forest by removing trees by hand or using heavy machinery is one of the few tools available to manage forests. However, finding the best way to thin forests by removing select trees to maximize the forest's benefits for water quantity, water quality, wildfire risk and wildlife habitat remains a challenge for resource managers.

Treating hospitalized COVID-19 patients with anticoagulants -- blood thinners that slow down clotting -- may improve their chances of survival, researchers report. The study could provide new insight on how to treat and manage coronavirus patients once they are admitted to the hospital.

Scientists have developed a method that combines different resolution levels in a computer simulation of biological membranes. Their algorithm backmaps a large-scale model that includes features, such as membrane curvature, to its corresponding coarse-grained molecular model. This has allowed them to zoom in on toxin-induced membrane budding and to simulate a full-sized mitochondrial lipid membrane. Their approach opens the way to whole-cell simulations at a molecular level.

New machine learning methods bring insights into how lithium ion batteries degrade, and show it's more complicated than many thought.

Some plants, like soybean, are known to possess an innate defense machinery that helps them develop resistance against insects trying to feed on them. However, exactly how these plants recognize signals from insects has been unknown until now. Scientists have now uncovered the cellular pathway that helps these plants to sense danger signals and elicit a response, opening doors to a myriad of agricultural applications.

Millions of people around the world use acid suppressants called proton pump inhibitors for conditions like heartburn, gastritis and stomach ulcers. Researchers at Karolinska Institutet in Sweden now report that how the long-term use of these drugs could increase the risk of developing dementia. Their results are published in the journal Alzheimer's & Dementia.

Evidence continues to mount that the Neanderthals, who lived in Europe and Asia until about 40,000 years ago, were more sophisticated people than once thought. A new study shows that Neanderthals chose to use bones from specific animals to make a tool for specific purpose: working hides into leather.

In many fish species body size plays an important role in sexual selection. Large individuals are preferred mating partners because they can enhance offspring survival by providing better quality resources than small individuals. While large females and males are often favored by sexual selection, fishing targets and removes these reproductively superior individuals.

Biologists have now used high-speed cameras to record how geckos orient their toes with shifting weight, especially when encountering slippery or rough patches, and found a remarkable ability to adjust toe orientation to stick and peel while running full speed.

New research describes a new model for how the brain interprets patterns in complex networks. They found that the ability to detect patterns stems in part from the brain's desire to represent things in the simplest way possible and that the brain is constantly weighing the pressures of complexity and simplicity when making decisions.
