Cheatgrass, an invasive annual grass that has invaded Nevada rangelands, is responsible for much of the increasing wildfire danger in the Intermountain West. However, scientists have discovered that fire danger can be reduced through the application of targeted cattle grazing in the dormant growing season by attracting the cattle with stations containing protein feed supplements.

Researchers have identified and reconstructed the first ancient genome of E. coli, using fragments extracted from the gallstone of a 16th century mummy.

A new study has unraveled the earliest evidence for domestication of a fruit tree, researchers report. The researchers analyzed remnants of charcoal from the Chalcolithic site of Tel Zaf in the Jordan Valley and determined that they came from olive trees. Since the olive did not grow naturally in the Jordan Valley, this means that the inhabitants planted the tree intentionally about 7,000 years ago.

Increasing frequency and size of wildfires in the United States over the past several decades affect everything from human life and health to air quality, biodiversity, and land use. The US dairy industry is not exempt from these effects. The Western states, where wildfires are especially prevalent, are home to more than two million dairy cows that produce more than 25% of the nation's milk. A new report examines how dairy cattle in the Western United States may be affected by unique air pollutants from wildfire smoke.

The violent death throes of a nearby star so thoroughly disrupted its planetary system that the dead star left behind -- known as a white dwarf -- is sucking in debris from both the system's inner and outer reaches, astronomers report.

Astronomers using data from the VLA Sky Survey have discovered one of the youngest known neutron stars -- possibly as young as only 14 years. The dense remnant of a supernova explosion was revealed when bright radio emission powered by the pulsar's powerful magnetic field emerged from behind a thick shell of debris from the explosion.

Space scientists have discovered a 'super Jupiter' orbiting a white dwarf, detected using direct observations with the European Space Agency (ESA)'s Gaia mission.

Archaeologists have located a unique Viking Age shipyard site at Birka on Björkö in Lake Mälaren. The discovery challenges previous theories about how the maritime activities of the Viking Age were organized.

NASA's Nancy Grace Roman Space Telescope will study wispy streams of stars that extend far beyond the apparent edges of many galaxies. Missions like the Hubble and James Webb space telescopes would have to patch together hundreds of small images to see these structures around nearby galaxies in full. Roman will do so in a single snapshot. Astronomers will use these observations to explore how galaxies grow and the nature of dark matter.

Astronomers have imaged the debris disk of the nearby star HD 53143 at millimeter wavelengths for the first time, and it looks nothing like they expected. Based on early coronagraphic data, scientists expected ALMA to confirm the debris disk as a face-on ring peppered with clumps of dust. Instead, the observations took a surprise turn, revealing the most complicated and eccentric debris disk observed to date.

Astronomers discovered a multiplanet system just 33 light-years from Earth, making it one of the closest known multiplanet systems. The system likely hosts at least two terrestrial, Earth-sized planets.

Astronomers have unveiled intricate details of the star-forming region 30 Doradus, also known as the Tarantula Nebula, using new observations from the Atacama Large Millimeter/submillimeter Array (ALMA). Now we can see the nebula in a new light, with wispy gas clouds that provide insight into how massive stars shape this region.

Finding forming planets is a tough but important job for astronomers: Only three planets have ever been discovered caught in the process of forming, and the most recent of these was found just weeks ago.

The Black Death, the biggest pandemic of our history, was caused by the bacterium Yersinia pestis and lasted in Europe between the years 1346 and 1353. Despite the pandemic's immense demographic and societal impacts, its origins have long been elusive. Now, scientists have obtained and studied ancient Y. pestis genomes that trace the pandemic's origins to Central Asia.

A new study in Ocean and Coastal Management shows that seagrass fisheries provide a reliable safety-net for poor, since fishermen perceive those habitats to maintain large fish catches over time. Surprisingly, even more so than coral reef fisheries, which people normally associate with small-scale fishery.

Researchers conducted an eight-year experiment that found that climate warming played a predominant role in shaping microbial biodiversity, with significant negative effect.
