Smaller earthquakes "with ambition" produce the most ground shaking
An earthquake of magnitude 8.0 or larger will almost always cause strong shaking, but a new study suggests that smaller earthquakes--those around magnitude 5.5 or so--are the cause of most occurrences of strong shaking at a 60-kilometer (37-mile) distance. (2020-11-04)

Galaxies in the very early universe were surprisingly mature
Massive galaxies were already much more mature in the early universe than previously expected. This is the conclusion of an international team of astronomers who studied distant galaxies with the Atacama Large Millimeter/submillimeter Array (ALMA). The result is now published by the National Radio Astronomy Observatory. (2020-10-30)

Surprisingly mature galaxies in the early Universe
When the Universe was only a tenth of its current age its galaxies experienced a growth spurt. It was this period that the scientists in the ALPINE project focused on when they used ESO's ALMA telescope to carry out the first ever large survey of distant galaxies. To their surprise, these galaxies observed in the early stages of their life were far more mature than expected. (2020-10-27)

Anemic star cluster breaks metal-poor record
In a surprising discovery, astronomers using two Maunakea Observatories - W. M. Keck Observatory and Canada-France-Hawaii Telescope (CFHT) - have found a star cluster in the Andromeda Galaxy that contains a record-breaking low amount of metals, calling into question the so-called 'metallicity-floor' for massive globular star clusters. (2020-10-15)

Empathy prevents COVID-19 spreading
The more empathetic we are, the more likely it is that we will keep our distance and use face masks to prevent coronavirus spreading. This study demonstrates that it is possible to increase our empathy and willingness to follow advice on social distancing and face masks. (2020-10-13)

Scientists find neurochemicals have unexpectedly profound roles in the human brain
In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals -- dopamine and serotonin -- are at work at sub-second speeds to shape how people perceive the world and take action based on their perception. (2020-10-12)

Astronomers turn up the heavy metal to shed light on star formation
Astronomers from The University of Western Australia's node of the International Centre for Radio Astronomy Research (ICRAR) have developed a new way to study star formation in galaxies from the dawn of time to today. Using a new algorithm to model the energy and wavelengths of light coming from almost 7000 nearby galaxies, the researchers succeeded in reconstructing when most of the stars in the Universe formed--in agreement with telescope observations for the first time. (2020-10-06)

ESO telescope spots galaxies trapped in the web of a supermassive black hole
With the help of ESO's Very Large Telescope, astronomers have found six galaxies lying around a supermassive black hole when the Universe was less than a billion years old. This is the first time such a close grouping has been seen so soon after the Big Bang and the finding helps us better understand how supermassive black holes formed and grew so quickly. It supports the theory that black holes can grow rapidly within large structures which contain plenty of gas to fuel them. (2020-10-01)

Gravity causes homogeneity of the universe
Gravity can accelerate the homogenization of space-time as the universe evolves. This insight is based on theoretical studies of the physicist David Fajman of the University of Vienna. The results have been published in the journal 'Physical Review Letters'. (2020-09-24)

Scientists detect first-of-its-kind 'intermediate-mass' black hole
An international research collaboration including Northwestern University astronomers has witnessed the birth of an ''intermediate-mass'' black hole. This is the first conclusive discovery of an intermediate-mass black hole, an object which has long eluded astronomers. The cosmic event, its energy detected on Earth in the form of gravitational waves, is the most massive black hole merger yet observed in gravitational waves. Two black holes likely collided and merged to create a more massive black hole. (2020-09-02)

Housing First proves cost effective especially for the most-vulnerable homeless group
Canadians spend big money dealing with the consequences of homelessness, but the money spent could be far more effective. According to a new McGill-led analysis, housing homeless people with severe mental illness is even more cost-effective than housing homeless people with moderate needs. A Housing-First strategy aimed at helping these individuals regain and keep permanent housing generates savings equal to about two-thirds of its cost. (2020-08-25)

Shrinking Tasmanian tigers: Resizing an Australian icon
The thylacine, that famous extinct Australian icon colloquially known as the Tasmanian Tiger, is revealed to have been only about half as big as once thought - not a ''big'' bad wolf after all. (2020-08-18)

Small towns have highest risk of intimate partner violence
Despite common perceptions that big cities have more violence, women living in small towns are most at risk of violence from current or former partners. The study analyzed the responses of more than 570,000 women from the National Crime Victimization Survey from 1994-2015. Women from small towns were 27% more likely to be victims of intimate partner violence than women from the center of big cities and 42% more likely than suburban women. (2020-08-06)

A new interdisciplinary effort led by a Mainz research group has now shown a realistic path to demonstrating this phenomenon. The approach includes aspects of nuclear, elementary particle, atomic and molecular physics as well as nuclear magnetic resonance (NMR). 'Molecular parity nonconservation in nuclear spin couplings' is published in the current issue of the journal Physical Review Research. (2020-06-03)

Deep learning: A new engine for ecological resource research
Deep learning is driven by big data, which brings new opportunities for target classification, detection, semantic segmentation, instance segmentation, and regression in ecological resource research. However, there are still great challenges in the standardization and sharing of data, the universality and interpretability of algorithms, and the enrichment and intelligence of applications. A recent study clarified the aforementioned frontier issues, which was published in the 'Science China Terrae' journal. (2020-05-21)

ALMA discovers massive rotating disk in early universe
In our 13.8 billion-year-old universe, most galaxies like our Milky Way form gradually, reaching their large mass relatively late. But a new discovery made with the Atacama Large Millimeter/submillimeter Array (ALMA) of a massive rotating disk galaxy, seen when the universe was only ten percent of its current age, challenges the traditional models of galaxy formation. This research appears on May 20, 2020, in the journal Nature. (2020-05-20)
