In creating five new isotopes, scientists have brought the stars closer to Earth. The isotopes are known as thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190.

New research reveals the scale of inappropriate reforestation projects across Africa. A new study reveals that an area the size of France is threatened by forest restoration initiatives, such as the AFR100 initiative (African Forest Landscape Restoration Initiative), due to inappropriate restoration in the form of tree-planting.

A new model bridges the rules of life at the individual scale and the ecosystem level, which could open new avenues of exploration in ecology, global change biology, and ultimately ecosystem management.

Researchers have completed one of the most extensive river resilience studies, examining how river ecosystems recover following floods. They developed a novel modeling approach that used data from oxygen sensors placed in rivers to estimate daily growth in aquatic plants and algae. The researchers then modeled the algal and plant biomass in 143 rivers across the contiguous U.S. to quantify what magnitude of flooding disturbs the biomass and how long the rivers take to recover from floods. Increased understanding of rivers' resiliency is important to maintaining healthy rivers, as human actions can affect flood regimes and change the conditions in rivers for other aquatic life that may rely on algae and plants as a food source.

If gravitational condensate stars (or gravastars) actually existed, they would look similar to black holes to a distant observer. Two theoretical physicists have now found a new solution to Albert Einstein's theory of general relativity, according to which gravitational stars could be structured like a Russian matryoshka doll, with one gravastar located inside another.

Corals searching for food in the cold and dark waters of the deep sea are building higher and higher mountains to get closer to the source of their food. But in doing so, they may find themselves trapped when the climate changes.

Global warming may be interacting with regional rainfall and deforestation to accelerate forest loss in the Amazon, pushing it towards partial or total collapse. New research has identified the potential thresholds of these stressors, showing where their combined effects could produce a 'tipping point' -- in which the forest is so fragile that just a small disturbance could cause an abrupt shift in the state of the ecosystem.

The Joro spider was first spotted stateside around 2013 and has since been spotted across Georgia and the Southeast. New research has found more clues as to why the spider has been so successful in its spread. The study found the invasive orb-weaving spider is surprisingly tolerant of the vibrations and noise common in urban landscapes. In this new study, researchers examined how Joro spiders can live next to busy roads, which are notably stressful environments for many animals.

Researchers find deforestation accounts for about 10 percent of global human-made mercury emissions. While it cannot be the only solution, they suggest reforestation could increase global mercury uptake by about 5 percent.

Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.

For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of heat flow in superconductors and neutron stars.

Two astrophysicists have finally solved a 20-year-old astrophysical puzzle concerning the lower-than-expected amounts of the element sulphur found in Planetary Nebulae (PNe) in comparison to expectations and measurements of other elements and other types of astrophysical objects. The expected levels of sulphur have long appeared to be 'missing in action'. However, they have now finally reported for duty after hiding in plain sight, as a result of leveraging highly accurate and reliable data.

New research reveals that denser, and more sheltered, kelp forests can withstand serious stressors amid warming ocean temperatures.

Employing massive data sets collected through NASA's James Webb Space Telescope, astronomers are unearthing clues to conditions existing in the early universe. The team has catalogued the ages of stars in the Wolf--Lundmark--Melotte (WLM) galaxy, constructing the most detailed picture of it yet, according to the researchers. WLM, a neighbor of the Milky Way, is an active center of star formation that includes ancient stars formed 13 billion years ago.

Extreme events wipe out entire forests, dramatically eliminating complex ecosystems as well as local communities. Researchers have become quite familiar with such attention-grabbing events over the years. They know less, however, about the more common moderate-severity disturbances, such as relatively small fires, ice storms, and outbreaks of pests or pathogens.

A carbon monoxide (CO)-runaway gap identified in the atmospheres of Earth-like planets can help expand the search for habitable planets. This gap, identified through atmospheric modeling, is an indicator of a CO-rich atmosphere on Earth-like planets orbiting Sun-like stars. CO is an important compound for the formation of prebiotic organic compounds, which are building blocks for more complex molecules for the formation of life.

Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests.

An experiment spanning more than two decades has found that removal of apex predators from an ecosystem can create lasting changes that are not reversed after they return -- at least, not for a very long time. The study challenges the commonly held belief that the reintroduction of wolves to Yellowstone National Park restored an ecosystem degraded by their absence.

New research sheds light on tiny plankton, which measure less than 0.02mm in diameter but can make up more than 70% of the plankton biomass found in the ocean.
