Materials scientists at Duke University have uncovered an atomic mechanism that makes certain thermoelectric materials incredibly efficient near high-temperature phase transitions. The information will help fill critical knowledge gaps in the computational modeling of such materials, potentially allowing researchers to discover new and better options for technologies that rely on transforming heat into electricity.

The results appear online on September 4 in the journal Nature Communications.

Thermoelectric materials convert heat into electricity when electrons migrate from the hot side of the material to the cold side. Because providing a temperature difference between its two sides is required, researchers are interested in trying to use these materials to generate electricity from the heat of a car’s tailpipe or recovering energy lost as heat in power plants.

Researchers from China continue in the quest to improve methods for bone regeneration, publishing their findings in “Cryogenic 3D printing of dual-delivery scaffolds for improved bone regeneration with enhanced vascularization.”

A wide range of projects have emerged regarding new techniques for bone regeneration—especially in the last five years as 3D printing has become more entrenched in the mainstream and bioprinting has continued to evolve. Bone regeneration is consistently challenging, and while bioprinting is still relatively new as a field, much impressive progress has been made due to experimentation with new materials, nanotubes, and innovative structures.

Cell viability is usually the biggest problem. Tissue engineering, while becoming much more successful these days, is still an extremely delicate process as cells must not only be grown but sustained in the lab too. For this reason, scientists are always working to improve structures like scaffolds, as they are responsible in most cases for supporting the cells being printed. In this study, the authors emphasize the need for both “excellent osteogenesis and vascularization” in bone regeneration.

The National Science Foundation has awarded a highly competitive $5 million grant to Vanderbilt University that greatly expands a School of Engineering-led project for creating novel AI technology and tools and platforms that train and support individuals with Autism Spectrum Disorder in the workplace.

The significant federal investment follows a successful $1 million, nine-month pilot grant to the same team that forged partnerships with employers and other stakeholders and produced viable prototypes through immersive, human-centric design. The multi-university team includes Yale University, Cornell University, Georgia Institute of Technology and Vanderbilt University Medical Center as academic partners.

The grant, made through NSF’s Convergence Accelerator program, advances the School of Engineering’s focus on Inclusion Engineering,® which uses the disciplines within engineering to broaden meaningful participation for people who have been marginalized.

For college students studying science, doing labwork as part of their classes is a vital way to learn research skills and better understand concepts from lectures.

That presents a challenge for schools that are operating remotely during the coronavirus pandemic — so some biology programs are mailing brains, eyeballs, and even entire fetal pigs to their students so they can dissect them at home.

At Lafayette College, neuroscience students enrolled in a physiology course recently received packages in the mail that contained preserved sheep brains, which are commonly chosen by schools due to their close resemblance to human brains. Then, neuroscientist and psychologist Luis Schettino — who, in the interest of transparency, was one of my professors when I attended Lafayette — guided his students over a video call as they dissected the brains.

Special delivery!

With thousands of students using the internet to attend class remotely, cybersecurity experts are raising concerns about children becoming targets for hackers. Many Central New York school districts, like the Central Square Central School District, sent laptops home with students. Central Square uses a software called GoGuardian that flags unsafe or inappropriate online material. Superintendent Thomas Colabufo says parents are happy to know that the security feature is in place.

Recently, San Diego Zoo partnered up with the wildlife preservation group Revive and Restore and a pet cloning company ViaGen Equine to create an exact copy of Kuporovic. The embryo was planted in a surrogate mother, a common horse.

Shawn Walker, the chief science officer at ViaGen Equine reports “This new Przewalski’s colt was born fully healthy and reproductively normal. He is head butting and kicking when his space is challenged, and he is demanding milk supply from his surrogate mother.”

This whole deal is not only good news for Przewalski’s horses, because this project demonstrates that we can keep genetic material viable for many years. Thus principles we see in action see here can potentially be applied to other endangered, even extinct species. Yes, you’ve read that right, Revive and Restore hopes to revive a wooly mammoth one day.

The is truly unique; as a single seat (or single plus pillion), twin jet, HSA Motorcycle, it is a world’s first in many ways. At just 2.3m long and under 1m wide, it is the smallest of all Gibbs High speed amphibious platforms, and very probably the most technically advanced. It represents true freedom for the individual; serious fun.
