Dish-grown brain-like organoids offer window into autism

(Salt Lake City) – Whatever you do, don’t call them “mini-brains,” say scientists at the University of Utah Health. Either way, the seed-sized organoids — which are grown in the lab from human cells — provide insight into the brain and reveal differences that may contribute to autism in some people. “We used to think …

Porous carbon, better batteries and working small to save the planet

AIBN PhD student Minjun Kim revolutionizes the storage and conversion of energy. As a nanoarchitect, PhD student Minjun Kim used to working small. But like many of his peers at the Australian Institute of Bioengineering and Nanotechnology, the scope of his research is immense. Minjun used science that could fit on the head of a …

Some everyday materials have memories, and now they can be erased

Some solid materials have a memory of how they have been stretched before, which impacts how they react to these types of deformations in the future. A new study from Penn State provides insight into memory formation in foams and emulsions common in food and pharmaceutical products and provides a new method for erasing that …

NASA study finds climate extremes affect landslides in surprising ways

Credit: public domain CC0 Climate change is driving more volatile precipitation patterns around the world – very dry expanses punctuated by storms that drop large amounts of rain or snow in a short period of time. Although wetter and drier periods can have some predictable effects, such as on water levels in lakes and rivers, …

Using chemo-mechanical oscillations to mimic the behavior of protocells in fabricated microcapsules

matter (2022). DOI: 10.1016/j.matt.2022.06.063″ width=”800″ height=”530″/> Credit: Oleg E. Shklyaev et al, Question (2022). DOI: 10.1016/j.matt.2022.06.063 The complexity of life on Earth stemmed from simplicity: from the earliest protocells to the growth of any organism, individual cells aggregate into basic clusters and then form more complex structures. Early cells lacked complicated biochemical machinery; to evolve …

Dozens of newly discovered gravitational lenses could reveal ancient galaxies and the nature of dark matter

Cambridge, MA – Earlier this year, a machine learning algorithm identified up to 5,000 potential gravitational lenses that could transform our ability to trace the evolution of galaxies since the Big Bang. Today, astronomer Kim-Vy Tran and his colleagues evaluated 77 of the lenses using the Keck Observatory in Hawai’i and the Very Large Telescope …

Scientists are using machine learning to accelerate materials discovery

The end product of the machine learning algorithm: the metastable phase diagrams for carbon. Colored regions indicate the conditions under which carbon exists in certain metastable states that can yield useful material properties.

Dinosaur-killing asteroid splashed mile-high tsunamis that swept across the globe

Credit: NASA/Don Davis. The asteroid that hit Earth off Mexico’s Yucatan Peninsula quite simply devastated all life on Earth, not just dinosaurs. The cosmic impact unleashed the force of 10 billion Hiroshima A-bombs and ejected gigatons of sulfur and carbon dioxide into the atmosphere, which could have lowered air temperatures on the surface of a …

Old plants may have new tricks to improve crop results, researchers report

Nearly 2,000 genebanks around the world hold the genetic resources of plants, from seed to stem and more, taken from all crops, even those that have never been cultivated or have not grown. for a century. These time capsules have the potential to improve future crops with unknown or previously unwanted genes as plant diseases …
