Scientists have analyzed data from Mexico's Ministry of Health to identify dengue fever hotspots. Working with epidemiologists at the University of North Texas and Universidad Autónoma de Nuevo León, the team calculated environmental and socioeconomic risk factors and mapped areas where severe outbreaks occur.

A research team examined what happens to mountain snowpacks when sunny, midwinter dry spells occur in forests impacted by severe wildfire.

Astronomers using data from the SMARTS 1.5-meter Telescope at the Cerro Tololo Inter-American Observatory (CTIO), have made the first confirmed detection of a star system that will one day form a kilonova -- the ultra-powerful, gold-producing explosion created by merging neutron stars. These systems are so phenomenally rare that only about 10 such systems are thought to exist in the entire Milky Way.

What happened shortly after the universe was born in the Big Bang and began to expand? Bubbles occurred and a previously unknown phase transition happened, according to particle physicists.

Sneaker waves are likely fueled by a specific type of wave condition generated by far-off storms and paired with just the right conditions closer to shore, a new study has found.

A group of scientists have released one of the most precise measurements ever made of how matter is distributed across the universe today.

A new conceptual framework for incorporating the way plants use carbon and water, or plant dynamics, into fine-scale computer models of wildland fire provides a critical first step toward improved global fire forecasting.

Data stored in ice cores dating back 55 years bring new insight into atmospheric levels of a molecule that can significantly affect weather and climate.

Honey bee colony loss across the United States over the last five years is primarily related to the presence of parasitic mites, nearby pesticides, and extreme weather events as well as challenges with overwintering, according to a new study. The study took advantage of novel statistical methods and is among the first to concurrently consider a variety of potential honey bee stressors at a national scale.

A giant diffuse tail of stars has been discovered emanating from a large, faint dwarf galaxy. The presence of a tail indicates that the galaxy has experienced recent interaction with another galaxy. This is an important clue for understanding how so called 'ultra-diffuse' galaxies are formed.

A handful of hyper-productive fisheries provide sustenance to a billion people and employ tens of millions. These fisheries occur on the eastern edges of the world's oceans -- off the West Coast of the U.S., the Canary Islands, Peru, Chile, and Benguela. There, a process called upwelling brings cold water and nutrients to the surface, which in turn supports large numbers of larger sea creatures that humans depend on for sustenance. A new project is seeking to understand how changes to the climate and oceans will impact fisheries in the U.S. and around the world.

Earth's potassium arrived by meteoritic delivery service finds new research led by Earth and planetary scientists. Their work shows that some primitive meteorites contain a different mix of potassium isotopes than those found in other, more-chemically processed meteorites. These results can help elucidate the processes that shaped our Solar System and determined the composition of its planets.

Scientists have discovered the first gamma-ray eclipses from a special type of binary star system using data from NASA's Fermi Gamma-ray Space Telescope. These so-called spider systems each contain a pulsar -- the superdense, rapidly rotating remains of a star that exploded in a supernova -- that slowly erodes its companion.

Europe lacks groundwater -- a lot of groundwater. The continent has already been suffering from a severe drought since 2018. This is confirmed by satellite data.

The most sensitive telescope now searching for radio signals from cosmic dawn, an era around 200 million years after the Big Bang when stars ignited, has doubled its sensitivity, a new paper reports. While not yet detecting this radiation -- the redshifted 21-centimeter line -- they have put new limits on the elemental composition of galaxies during the Epoch of Reionization. Early galaxies seem to be low in metals, fitting the most popular theory of cosmic evolution.

Space weather can interfere with spaceflight and the operation of satellites, but the phenomenon is very difficult to study on Earth because of the difference in gravity. Researchers effectively reproduced the type of gravity that exists on or near stars and other planets inside of a glass sphere measuring 3 centimeters in diameter, or about 1.2 inches. The achievement could help scientists overcome the limiting role of gravity in experiments that are intended to model conditions in stars and other planets.

Researchers recently announced that salt marshes, critical habitats threatened by rapid sea-level rise, may in fact thrive despite higher water levels. The key factor that determines whether salt marshes collapse or flourish involves not water, but sediment.

Astronomers used observations from the James Webb Space Telescope (JWST) to achieve the darkest ever view of a dense interstellar cloud. These observations have revealed the composition of a virtual treasure chest of ices from the early universe, providing new insights into the chemical processes of one of the coldest, darkest places in the universe as well as the origins of the molecules that make up planetary atmospheres.

A startling analysis from Globe at Night -- a citizen science program -- concludes that stars are disappearing from human sight at an astonishing rate. The study finds that, to human eyes, artificial lighting has dulled the night sky more rapidly than indicated by satellite measurements.

Research has revealed how supermassive black holes (SMBHs) are feeding off gas clouds which reach them by traveling hundreds of thousands of light years from one galaxy to another.
