An en‘light’ening approach to cancer treatment: New GO-templated gold nanosheet shows promise for photothermal therapy

By Lisa McDonald / November 13, 2020

Traditional methods of surgery, chemotherapy, and radiotherapy for treating cancer can be extremely taxing on the body. Photothermal therapy is a minimally invasive and locally focused alternative, and a recent paper by researchers in China looks at the potential of a new graphene oxide-templated gold nanosheet for use in this treatment.

Wouldn’t ewe know it—titanium-reinforced bioceramic implant induces cranial regrowth in sheep

By Lisa McDonald / October 16, 2020

In recent years, calcium phosphate ceramics are playing a bigger role in research on materials for cranioplasty grafts. Researchers from Sweden now showed the potential of a titanium-reinforced bioceramic containing several calcium phosphate phases to stimulate regeneration of bone in large cranial defects in sheep.

Video: Vitrification of human tissue

By Lisa McDonald / July 22, 2020

Vitrification is the process through which a material turns into a glass or glasslike substance by undergoing rapid cooling. Though the discovery this year that a man’s brain vitrified during the Mount Vesuvius eruption surprised some people, vitrification of human tissue is actually a well-established practice in fertility treatment.

How effective is that mask? Depends on what materials it is made of

By April Gocha / July 21, 2020

There is no shortage of options available when shopping for nonmedical face masks, yet most provide little information about their filter efficiency and breathability—important considerations for a mask that is both efficient and comfortable. But a recent study offers more complete data on the performance of an array of common materials.

Say goodbye to nasal swabs—researchers use breathalyzers to detect COVID-19

By Lisa McDonald / June 30, 2020

Deep nasal swabs are currently the main testing method for COVID-19. Researchers at The Ohio State University are investigating using a specially designed breathalyzer instead, which has the potential to provide results faster and at less cost.
