Part 1 on the Race to Create a Permanent Human Presence in Low-Earth-Orbit

Posted by in category: space travel

A commercial space station called Orbital Reef may be deployed this decade, one of many planned for low-Earth orbit.


In Part 1 looking at LEO space station deployment we focus on two front runners: the Axiom Space Station and Blue Origin’s Orbital Reef.

The Most Beautiful Strongly Bound Dibaryon

Posted by in categories: cosmology, particle physics

Dibaryons are subatomic particles composed of two baryons. Their formation, which occurs through interactions between baryons, is fundamental in big-bang nucleosynthesis, nuclear reactions including those happening within stars, and bridges the gap between nuclear physics, cosmology, and astrophysics. Fascinatingly, the strong force, responsible for the formation and the majority of the mass of nuclei, facilitates the formation of a plethora of different dibaryons with diverse quark combinations.

Nevertheless, these dibaryons are not commonly observed — the deuteron is currently the only known stable dibaryon.

To resolve this apparent dichotomy, it is essential to investigate dibaryons and baryon-baryon interactions at the fundamental level of strong interactions. In a recent publication in Physical Review Letters.

Improving crystal engineering with DNA

Posted by in categories: biotech/medical, engineering, nanotechnology

Northwestern investigators have demonstrated that fine-tuning DNA interaction strength can improve colloidal crystal engineering to enhance their use in creating an array of functional nanomaterials, according to a recent study published in ACS Nano.

Chad Mirkin, Ph.D., professor of Medicine in the Division of Hematology and Oncology, the George B. Rathmann Professor of Chemistry at Northwestern’s Weinberg College of Arts and Sciences, and director of the International Institute for Nanotechnology, was senior author of the study.

Colloidal crystal engineering with DNA involves modifying nanoparticles into programmable atom equivalents, or “PAEs,” which are used to form that can then be used for designing programmable, synthetic DNA sequences.

He likes to be, under the sea: Florida man sets record for living underwater

Posted by in categories: biotech/medical, education, engineering

But Dituri isn’t just settling for the record and resurfacing: He plans to stay at the lodge until June 9, when he reaches 100 days and completes an underwater mission dubbed Project Neptune 100.

The mission combines medical and ocean research along with educational outreach and was organized by the Marine Resources Development Foundation, owner of the habitat.

“The record is a small bump and I really appreciate it,” said Dituri, a University of South Florida educator who holds a doctorate in biomedical engineering and is a retired U.S. Naval officer. “I’m honored to have it, but we still have more science to do.”
