Detailed Supercomputer Simulation of the Universe Creates Structures Very Similar to the Milky Way

Posted by in categories: cosmology, evolution, physics, supercomputing

In their pursuit of understanding cosmic evolution, scientists rely on a two-pronged approach. Using advanced instruments, astronomical surveys attempt to look farther and farther into space (and back in time) to study the earliest periods of the Universe. At the same time, scientists create simulations that attempt to model how the Universe has evolved based on our understanding of physics. When the two match, astrophysicists and cosmologists know they are on the right track!

In recent years, increasingly-detailed simulations have been made using increasingly sophisticated supercomputers, which have yielded increasingly accurate results. Recently, an international team of researchers led by the University of Helsinki conducted the most accurate simulations to date. Known as SIBELIUS-DARK, these simulations accurately predicted the evolution of our corner of the cosmos from the Big Bang to the present day.

In addition to the University of Helsinki, the team was comprised of researchers from the Institute for Computational Cosmology (ICC) and the Centre for Extragalactic Astronomy at Durham University, the Lorentz Institute for Theoretical Physics at Leiden University, the Institut d’Astrophysique de Paris, and The Oskar Klein Centre at Stockholm University. The team’s results are published in the Monthly Notices of the Royal Astronomical Society.

Social working memory abnormalities may be a neurocognitive mechanism underlying poorer social connection in PTSD

Posted by in category: neuroscience

Research published in the journal Depression & Anxiety provides evidence that neurocognitive abnormalities are related to difficulties in social connection among people with posttraumatic stress disorder. The findings suggest that those with PTSD are more likely to struggle with managing multiple pieces of social information.

Approximately 7% of the population will have PTSD at some point in their lives, according to the National Institute of Mental Health. The disorder is characterized by persistent and intrusive memories of traumatic events, disrupted sleep, and other symptoms. PTSD has also been tied to social isolation and feelings of loneliness.

The researchers behind the new study sought to better understand whether the link between PTSD and isolation was related to specific impairments in neurocognitive mechanisms that support social cognition. They were particularly interested in social working memory, which describes the ability to maintain and manipulate information about people’s mental states, personalities, and relationships.

Single test for over 50 genetic diseases will cut diagnosis from decades to days

Posted by in categories: biotech/medical, genetics

Further research shows that the test is accurate.

When it comes to genetic neurological and neuromuscular diseases, screening early is key to getting the right treatment. A new DNA test developed by researchers at the Garvan Institute of Medical Research in Sydney may help in this process, as reported by the institution in a press release published on Saturday.


Garvan researchers have shown how new genomic sequencing technology can reduce the ‘diagnostic odyssey’ experienced by people with rare neurological and neuromuscular diseases.

Seldom Has Politics Superseded the Pursuit of Scientific Discovery and Sharing

Posted by in category: space

Even when politicians and countries have sparred, pursuing scientific truths has been a shared experience across academia and political boundaries. But not now with Russia’s invasion of Ukraine.


In response to the invasion of Ukraine programs of cooperation between Europe, North Americas, and Russia in space and research are ending.

How the Webb Telescope will reveal invisible features of the universe

Posted by in category: space

Joseph DePasquale, the senior data imaging developer at Space Telescope Science Institute, did some minor stretching of the image to bring out more of the detail of the star in the constellation Ursa Major known as HD 84406.


NASA’s James Webb Telescope will capture images in infrared light, providing a new perspective on the cosmos.
