Supermassive black hole appears to grow like a baby star      (via sciencedaily.com)     Original source 

Supermassive black holes pose unanswered questions for astronomers around the world, not least 'How do they grow so big?' Now, an international team of astronomers has discovered a powerful rotating, magnetic wind that they believe is helping a galaxy's central supermassive black hole to grow. The swirling wind, revealed with the help of the ALMA telescope in nearby galaxy ESO320-G030, suggests that similar processes are involved both in black hole growth and the birth of stars.

Non-native plants and animals expanding ranges 100 times faster than native species      (via sciencedaily.com)     Original source 

An international team of scientists has recently found that non-native species are expanding their ranges many orders of magnitude faster than native ones, in large part due to inadvertent human help. Even seemingly sedentary non-native plants are moving at three times the speed of their native counterparts in a race where, because of the rapid pace of climate change and its effect on habitat, speed matters. To survive, plants and animals need to be shifting their ranges by 3.25 kilometers per year just to keep up with the increasing temperatures and associated climactic shifts -- a speed that native species cannot manage without human help.

What happens when neutron stars collide?      (via sciencedaily.com)     Original source 

New simulations show that hot neutrinos created at the interface of merging binary neutron stars are briefy trapped and remain out of equilibrium with the cold cores of the stars for 2 to 3 milliseconds.

Natural hazards threaten over three thousand species      (via sciencedaily.com)     Original source 

Natural hazards can speed up the extinction process of land animals that have limited distribution and/or small populations. But there is hope to turn the negative development around, says researchers behind new study.

Restored rat-free islands could support hundreds of thousands more breeding seabirds      (via sciencedaily.com)     Original source 

Archipelago case-study shows that removing invasive rats and restoring native vegetation could help bring back hundreds of thousands of breeding pairs of seabirds lost to tropical islands. Calculating that there are enough fish to sustain restored seabird populations should be an important consideration for restoration projects, scientists say. Restored seabird populations also provide huge boost to the health of surrounding coral reef ecosystems through restored nutrient cycles.

Astronomers see a massive black hole awaken in real time      (via sciencedaily.com)     Original source 

In late 2019 the previously unremarkable galaxy SDSS1335+0728 suddenly started shining brighter than ever before. To understand why, astronomers have used data from several space and ground-based observatories, including the European Southern Observatory's Very Large Telescope (ESO's VLT), to track how the galaxy's brightness has varied. In a study out today, they conclude that they are witnessing changes never seen before in a galaxy -- likely the result of the sudden awakening of the massive black hole at its core.

Modified gravity theory: A million light years and still going      (via sciencedaily.com)     Original source 

In a breakthrough discovery that challenges the conventional understanding of cosmology, scientists have unearthed new evidence that could reshape our perception of the cosmos. New research shows that rotation curves of galaxies stay flat indefinitely far out, corroborating predictions of modified gravity theory as an alternative to dark matter.

Early Homo sapiens facilitated the establishment of the Bonelli's eagle in the Mediterranean 50,000 years ago      (via sciencedaily.com)     Original source 

Scientists have unraveled the ancestral history of one of the most iconic birds of prey in the current Iberian fauna: the Bonelli's eagle (Aquila fasciata). The study combines evidence from several disciplines, including palaeontology, genetics and ecology, to answer questions about when and why the Bonelli's eagle, a species primarily found in tropical and subtropical areas, colonized the Mediterranean Basin.

A conservation market could incentivize global ocean protection      (via sciencedaily.com)     Original source 

Thirty-by-thirty: protect 30% of the planet by 2030. While conservation is popular in principle, the costs of actually enacting it often stall even the most earnest efforts. Researchers have now proposed a market-based approach to achieving the 30x30 targets in the ocean.
