12-Year-Old Wins $25,000 Science Prize for Research on ‘Imaginary Colors’

A 12-year-old girl from Chappaqua, New York won $25,000 at the Broadcom MASTERS (Math, Applied Science, Technology and Engineering as Rising Stars), a Society for Science and the Public program, for her research into imaginary colors.

 

Ishana Kumar was one of 30 finalists recognized in the program, according to National Public Radio. She took home the Samueli Foundation Prize of $25,000 on Oct. 21.

The seventh-grader explored the possibility of how to change someone’s perception of imaginary colors using Benham’s top, a disk with white and black patterns that causes observers to see different colors when it spins to create retinal fatigue.

Due to the pandemic, she used a small testing sample of 10 friends and neighbors to run her experiment.

Kumar explained that if a person looked at a red object for a long time then stared at a sheet of white paper,

Migration and molt affect how birds change their colors — ScienceDaily

In late summer and autumn, millions of birds fly above our heads, often at night, winging their way toward their wintering grounds.

Before the journey, many birds molt their bright feathers, replacing them with a more subdued palette. Watching this molt led scientists to wonder how feather color changes relate to the migrations many birds undertake twice each year. Molt matters — not only because replacing worn feathers is necessary for flight, but because molt is the catalyst for plumage changes that affect whether birds find mates and reproduce.

“We’re really blessed here, as nature lovers and birdwatchers, that we have lots of species of warblers here, which come in blues, greens, red and yellows,” said Jared Wolfe, assistant professor in Michigan Technological University’s College of Forest Resources and Environmental Science and one of the founders of the Biodiversity Initiative. “These brightly colored birds migrate and nest here and then

New technology allows cameras to capture colors invisible to the human eye

New research from Tel Aviv University will allow cameras to recognize colors that the human eye and even ordinary cameras are unable to perceive.

The technology makes it possible to image gases and substances such as hydrogen, carbon and sodium, each of which has a unique color in the infrared spectrum, as well as biological compounds that are found in nature but are “invisible” to the naked eye or ordinary cameras. It has groundbreaking applications in a variety of fields from computer gaming and photography as well as the disciplines of security, medicine and astronomy.

The research was conducted by Dr. Michael Mrejen, Yoni Erlich, Dr. Assaf Levanon and Prof. Haim Suchowski of TAU’s Department of Physics of Condensed Material. The results of the study were published in the October 2020 issue of Laser & Photonics Reviews.

“The human eye picks up photons at wavelengths between 400 nanometers and

The Codex Cospi is one of the few Aztec ‘books’ in the world and it is kept at Bologna University Library. A new research project will investigate with unprecedented detail the painting techniques and tools with which it was made.


There are very few pre-Columbian manuscripts in the world; the Codex Cospi is one of them. These days, this manuscript is being analyzed at Bologna University Library in collaboration with Palazzo Poggi Museum (University Museum System). Using cutting-edge non-invasive techniques, researchers will try to figure out the composition of the bright colors with which the codex was embellished between the end of the 15th century and the beginning of the 16th.

Carisbo Foundation provided the funding (Art and Culture grant) to the Department of History, Cultures, and Civilization
