soap bubble : a hollow iridescent globe formed by blowing a film of soapsuds (as from a pipe) — Webster
Soap bubble is an extremely thin film of soapy water enclosing air that forms a hollow sphere with an iridescent surface. Soap bubbles usually last for only a few seconds before bursting, either on their own or on contact with another object. They are often used for children’s enjoyment, but they are also used in artistic performances. Assembling several bubbles results in foam. When light shines onto a bubble it appears to change color. Unlike those seen in a rainbow, which arise from differential refraction, the colors seen in a soap bubble arise from interference of light reflecting off the front and back surfaces of the thin soap film. Depending on the thickness of the film, different colors interfere constructively and destructively. — Wikipedia

Thin-skinned solar panels printed with inkjet
on August 27, 2020 at 12:20 pm
Solar cells can now be made so thin, light and flexible that they can rest on a soap bubble. The new cells, which efficiently capture energy from light, could offer an alternative way to power novel electronic devices, such as medical skin patches, where conventional energy sources are unsuitable.
Ripple effects after slow-motion bubble collapse
on August 17, 2020 at 3:20 pm
A recent feature cover photo on Science portrayed a bubble in mid-collapse, based on a study conducted by Alexandros T. Oratis et al. The research team in mechanical engineering, mathematics and aerospace engineering at Boston University, MIT and Princeton University demonstrated the formation of intriguing wave-like patterns when bubbles underwent collapse. Using a complex lighting setup and fast shutter speed in the lab, perfectly aligned to capture a fleeting moment, within one second, they […]
Weightless action on the space station – power,...

European science progressed at a slower pace on the International Space Station in the past month. As a series of spacewalks to power up the space habitat came to an end and two of its passengers left for home Earth, intriguing bubbles puzzled researchers and left them wanting to know more.

Between March 21 and 28, as the country enacted quarantine measures, the United States experienced a 3,000% jump in joblessness claims. By the end of March, a stock market drop had wiped out all gains from the previous three years.

Soap bubbles facilitated the pollination of a pear orchard by delivering pollen grains to targeted flowers, demonstrating that this whimsical technique can successfully pollinate fruit-bearing plants. The study, from the Japan Advanced Institute of Science and Technology in Nomi, Japan, and published June 17 in the journal iScience, suggests that soap bubbles may present a low-tech complement to robotic pollination technology designed to supplement the work of vanishing bees.
Potential beginning of life simulated in lab
on June 12, 2020 at 12:36 pm
Did life originate underground? Scientists at the University of Duisburg-Essen (UDE) have substantiated their theory that life could have begun deep in the Earth's crust. In their experiments, structures that were inanimate developed survival strategies within a short time.

The iridescence of marble berries and the clever, light-bending perforations of microalgae are inspiring scientists to create biodegradable glitter and makeup pigments, and bionic algae to use in lasers or to clean pollutants.
CRISPR plants: new non-GMO method to edit plants
on May 13, 2020 at 5:10 pm
An NC State researcher has developed a new way to get CRISPR/Cas9 into plant cells without inserting foreign DNA. This allows for precise genetic deletions or replacements, without inserting foreign DNA. Therefore, the end product is not a genetically modified organism, or GMO.
