Could this copycat black hole be a new type of star?      (via sciencedaily.com)     Original source 

It looks like a black hole and bends light like a black hole, but it could actually be a new type of star. Though the mysterious object is a hypothetical mathematical construction, new simulations by Johns Hopkins researchers suggest there could be other celestial bodies in space hiding from even the best telescopes on Earth.

The diversity of present tree species is shaped by climate change in the last 21,000 years      (via sciencedaily.com)     Original source 

A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.

Biological invasions as costly as natural disasters      (via sciencedaily.com)     Original source 

Over the past 40 years, the financial losses caused by biological invasions have been equivalent to those caused by various types of natural disasters, such as earthquakes, floods or storms; however, according to scientists, they are now increasing at a faster pace.

Coastal species persist on high seas on floating plastic debris      (via sciencedaily.com)     Original source 

The high seas have been colonized by a surprising number of coastal marine invertebrate species, which can now survive and reproduce in the open ocean, contributing strongly to the floating community composition. Researchers found coastal species, representing diverse taxonomic groups and life history traits, in the eastern North Pacific Subtropical Gyre on over 70 percent of the plastic debris they examined. Further, the debris carried more coastal species than open ocean species.

New exoplanet discovered      (via sciencedaily.com)     Original source 

Astronomers report the first exoplanet jointly discovered through direct imaging and precision astrometry, a new indirect method that identifies a planet by measuring the position of the star it orbits. Data from the Subaru Telescope in Hawai`i and space telescopes from the European Space Agency (ESA) were integral to the team's discovery.

M87 in 3D: New view of galaxy helps pin down mass of the black hole at its core      (via sciencedaily.com)     Original source 

From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose central supermassive black hole has already been imaged by the Event Horizon Telescope. M87 turns out to be triaxial, like a potato. The revised view provides a more precise measure of the mass of the central black hole: 5.37 billion solar masses.

James Webb Space Telescope images challenge theories of how universe evolved      (via sciencedaily.com)     Original source 

Astronomers find that six of the earliest and most massive galaxy candidates observed by the James Webb Space Telescope so far appear to have converted nearly 100% of their available gas into stars, a finding at odds with the reigning model of cosmology.

Wildfires and animal biodiversity      (via sciencedaily.com)     Original source 

Wildfires. Many see them as purely destructive forces, disasters that blaze through a landscape, charring everything in their paths. But a new study reminds us that wildfires are also generative forces, spurring biodiversity in their wakes.

Researchers discover tiny galaxy with big star power using James Webb telescope      (via sciencedaily.com)     Original source 

Using new observations from the James Webb Space Telescope, astronomers looked more than 13 billion years into the past to discover a unique, minuscule galaxy that could help astronomers learn more about galaxies that were present shortly after the Big Bang.

Humans need Earth-like ecosystem for deep-space living      (via sciencedaily.com)     Original source 

Can humans endure long-term living in deep space? The answer is a lukewarm maybe, according to a new theory describing the complexity of maintaining gravity and oxygen, obtaining water, developing agriculture and handling waste far from Earth.

British flower study reveals surprise about plants' sex life      (via sciencedaily.com)     Original source 

A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces.  When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.

Lightning strike creates phosphorus material      (via sciencedaily.com)     Original source 

A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.

New findings that map the universe's cosmic growth support Einstein's theory of gravity      (via sciencedaily.com)     Original source 

Research by the Atacama Cosmology Telescope collaboration has culminated in a groundbreaking new image that reveals the most detailed map of dark matter distributed across a quarter of the entire sky, reaching deep into the cosmos. Findings provide further support to Einstein's theory of general relativity, which has been the foundation of the standard model of cosmology for more than a century, and offers new methods to demystify dark matter.

Trees in areas prone to hurricanes have strong ability to survive even after severe damage      (via sciencedaily.com)     Original source 

The island of Dominica took a direct hit from Category 5 Hurricane Maria. Nine months afterward, researchers found that while 89% percent of trees located in nine previously documented forest stands were damaged, but only 10 percent had immediately died. The most common damage was stem snapping and major branch damage. The damage with the highest rates of mortality were uprooting and being crushed by a neighboring tree. Large individual trees and species with lower wood density were susceptible to snapping, uprooting and mortality. Those on steeper slopes were more prone to being crushed by neighboring trees.

Rooting out how plants control nitrogen use      (via sciencedaily.com)     Original source 

Nitrogen is such a crucial nutrient for plants that vast quantities of nitrogen-containing fertilizers are spread on farmlands worldwide. However, excess nitrogen in the soil and in drainage run-off into lakes and rivers causes serious ecological imbalances. A recent study has uncovered the regulatory mechanisms at work when plants utilize nitrogenous fertilizers in their roots, a positive step in the quest to generate crops that require less fertilizer while still producing the yields needed to feed the world.

Webb reveals never-before-seen details in Cassiopeia A      (via sciencedaily.com)     Original source 

The explosion of a star is a dramatic event, but the remains the star leaves behind can be even more dramatic. A new mid-infrared image from NASA's James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion seen from Earth 340 years ago. Cas A is the youngest known remnant from an exploding, massive star in our galaxy, which makes it a unique opportunity to learn more about how such supernovae occur.
