Record-Breaking Simulations of Large-Scale Structure Formation in the Universe

Researchers led by the University of Tsukuba present computer simulations that capture the complex dynamics of elusive neutrinos left over from the Big Bang

Current simulations of cosmic structure formation do not accurately reproduce the properties of ghost-like particles called neutrinos that have been present in the Universe since its beginning. But now, a research team from Japan has devised an approach that solves this problem.

In a study published this month in SC ’21: Proceedings of the International Conference for High Performance Computing, Networking, Storage and Analysis, researchers at the University of Tsukuba, Kyoto University, and the University of Tokyo report simulations that precisely follow the dynamics of such cosmic relic neutrinos...

A Daily Dose of Yoghurt could be the go-to food to Manage High Blood Pressure

Whether it’s a dollop on your morning cereal or a simple snack on the go, a daily dose of yoghurt could be the next go-to food for people with high blood pressure, according to new research from the University of South Australia.

Conducted in partnership with the University of Maine, the study examined the associations between yoghurt intake, blood pressure and cardiovascular risk factors, finding that yoghurt is associated with lower blood pressure for those with hypertension.

Globally, more than a billion people suffer from hypertension (high blood pressure), putting them at greater risk of cardiovascular diseases (CVDs) such as heart attack and stroke.

CVDs are the leading cause of death worldwide – in the United States, one person dies from CVD every 36 seconds; in Aust...

Liquid Crystals for Fast Switching Devices

Credit: CC0 Public Domain

An international team has investigated a newly synthesized liquid-crystalline material that promises applications in optoelectronics. Simple rod-shaped molecules with a single center of chirality self-assemble into helical structures at room temperature. Using soft X-ray resonant scattering at BESSY II, the scientists have now been able to determine the pitch of the helical structure with high precision. Their results indicate an extremely short pitch at only about 100 nanometres which would enable applications with particularly fast switching processes.

Liquid crystals are not solid, but some of their physical properties are directional — like in a crystal. This is because their molecules can arrange themselves into certain patterns...

Iron integral to the Development of Life on Earth – and the Possibility of Life on Other Planets

Early Earth on the left, had seas infused with life-enhancing iron, whereas Earth today, seen on the right, does not.

Researchers at the University of Oxford uncover the importance of iron for the development of complex life on Earth – which also may hint at the likelihood of complex life on other planets.

Iron is an essential nutrient that almost all life requires to grow and thrive. Iron’s importance goes all the way back to the formation of the planet Earth, where the amount of iron in the Earth’s rocky mantle was ‘set’ by the conditions under which the planet formed and went on to have major ramifications for how life developed...
