Scientists have developed a quantum experiment that allows them to study the dynamics, or behavior, of a special kind of theoretical wormhole.

Reforestation projects should include a variety of tree species and ensure genetic diversity within each species to maximize new forests' health and productivity.

Researchers have been able to make some key determinations about the first galaxies to exist, in one of the first astrophysical studies of the period in the early Universe when the first stars and galaxies formed, known as the cosmic dawn.

By dispersing seeds, animals can rapidly reestablish plant diversity in degraded forests.

Pioneering a new technique, researchers have peered into the extremely faint light that exists between galaxies to describe the history and state of orphan stars.

About 600 seemingly disparate fungi that had resisted categorization have been shown to have a common ancestor, according to a a research team that used genome sequencing to give these peculiar creatures a new classification home.

The European robin's closest relatives are found in tropical Africa. The European robin is therefore not closely related to the Japanese robin, despite their close similarity in appearance. This is confirmed by a new study of the Old World flycatcher family, to which these birds belong. The study comprises 92 per cent of the more than 300 species in this family.

Differences among the collection of bacteria and other microorganisms that live within birds' digestive tracts -- their gut microbiomes -- are not primarily driven by diet diversity, contrary to a recently proposed hypothesis. Instead, a team of researchers found that evolution may play a larger role in explaining these differences, which could potentially have implications for how these species adapt to new habitats.

Astronomers have developed the most extensive inventory to date of the galaxies where short gamma-ray bursts (SGRBs) originate. Using several highly sensitive instruments and sophisticated galaxy modeling, the researchers pinpointed the galactic homes of 84 SGRBs and probed the characteristics of 69 of the identified host galaxies.

A research team has reconstructed the origin of an unusual gravitational wave signal. The signal GW190521 may result from the merger of two massive black holes that captured each other in their gravitational field and then collided while spinning around each other in a rapid, eccentric motion.

A few days after officially starting science operations, NASA's James Webb Space Telescope propelled astronomers into a realm of early galaxies, previously hidden beyond the grasp of all other telescopes until now.

A 30-year tree planting campaign in Portland, Oregon, allowed researchers to show that the number of trees planted in the street is associated with reductions in mortality, and that the association grows stronger as the trees age and grow.

On average, about half of trees planted in tropical and sub-tropical forest restoration efforts do not survive more than five years, but there is enormous variation in outcomes, new research has found.

The Subaru Telescope successfully demonstrated engineering first light with a new instrument that will use about 2400 fiberoptic cables to capture the light from heavenly objects. Full operation is scheduled to start around 2024. The ability to observe thousands of objects simultaneously will provide unprecedented amounts of data to fuel Big Data Astronomy in the coming decade.

Three different moments in a far-off supernova explosion were captured in a single snapshot by NASA's Hubble Space Telescope. The star exploded more than 11 billion years ago, when the universe was less than a fifth of its current age of 13.8 billion years.

A supernova is a stellar explosion, which occurs when the lives of some really massive stars come to an end. In this violent epilogue, the star expels the material from its outer layers by means of a shock wave, allowing us to see the various elements it was composed of.

An international research team has measured the size of a star dating back more than 11 billion years ago using images that show the evolution of the star exploding and cooling. The research could help scientists learn more about the early Universe.

A study has found evidence that the evolution of tree roots over 300 million years ago triggered mass extinction events through the same chemical processes created by pollution in modern oceans and lakes.

Woody climbing plants, known as lianas, are more likely to infest smaller trees in Malaysian forests and therefore stop them growing to their full potential, which may have implications for climate change.

Astronomers have identified the oldest star in our galaxy that is accreting debris from orbiting planetesimals, making it one of the oldest rocky and icy planetary systems discovered in the Milky Way.
