For students of color, online racism leads to real-world mental health challenges
For college students of color who encounter online racism, the effect of racialized aggressions and assaults reaches far beyond any single social media feed and can lead to real and significant mental health impacts - even more significant than in-person experiences of racial discrimination, according to a recently published study from researchers at UConn and Boston College.

White contours induce red hue
A color illusion that strongly induces color contrast effect has been found by a research team at the Toyohashi University of Technology. The powerful visual illusion clarified a century-old contradiction relating to simultaneous color contrast theory. The team demonstrated that the presence or absence of flanking contours formed from extremely thin white lines could be used to switch between contradictory visual phenomena. This solution is expected to contribute to industrial design and high-definition imaging. (2021-02-10)

Color is in the eye of the beholder
Researchers led by Harvard University develop a novel method to express long wavelength invertebrate opsin proteins in vitro and detail the molecular structure of long- and short-wavelengths in the opsins of the lycaenid butterfly, Eumaeus atala, discovering previously unknown opsins that result in red-shifted long wavelength sensitivity in their visual system. The new method pinpoints the specific base pair changes responsible for the spectral tuning of these visual proteins and reveal how vision genes evolved. (2021-02-09)

Human eye beats machine in archaeological color identification test
A ruler and scale can tell archaeologists the size and weight of a fragment of pottery - but identifying its precise color can depend on individual perception. So, when a handheld color-matching gadget came on the market, scientists hoped it offered a consistent way of determining color, free of human bias. (2021-02-09)

Sensor and detoxifier in one
Ozone is a problematic air pollutant that causes serious health problems. A newly developed material not only quickly and selectively indicates the presence of ozone, but also simultaneously renders the gas harmless. As reported by Chinese researchers in Angewandte Chemie, the porous '2-in-one systems' also function reliably in very humid air. (2021-02-05)

CCNY's David Lohman finds Asian butterfly mimics different species as defense mechanism
Many animal and insect species use Batesian mimicry - mimicking a poisonous species - as a defense against predators. The common palmfly, Elymnias hypermnestra (a species of satyrine butterfly), which is found throughout wide areas of tropical and subtropical Asia, adds a twist to this evolutionary strategy: the females evolved two distinct forms, either orange or dark brown, imitating two separate poisonous model species, Danaus or Euploea.

Asian butterfly mimics other species to defend against predators
Many animal and insect species use Batesian mimicry -- mimicking a poisonous species -- as a defense against predators. The common palmfly Elymnias hypermnestra -- a species of satyrine butterfly that is found throughout wide areas of tropical and subtropical Asia -- adds a twist to this evolutionary strategy.

Counseling clients of color affected by COVID-19
An article published in the Journal of Counseling & Development examines how pre-existing racial and ethnic disparities, exacerbated by COVID-19, have negatively affected communities of color that tend to be overrepresented in lower socioeconomic groups, have limited access to health care and education, have an undocumented status, and work in jobs considered ''essential.'' (2020-12-10)

Racial microaggressions contribute to disparities in STEM education
Careers in science, technology, engineering, and mathematics (STEM) are one of the fastest-growing areas of work in the United States, yet racial and gender disparities remain in STEM occupations. A recent study from University of Illinois researchers examining reasons for such disparities shows the overall racial climate on a college campus--informed by experiences of racial microaggressions--is a contributing factor in the lack of representation of students of color in STEM education programs. (2020-12-08)

Appearances can be deceiving: Display versus surface colors
The white of paper and the white of monitor can be precisely the same color values, yet they appear fundamentally different. That disparity may not lie in the mode of display, but rather how the colors are constructed, according to a research team at Yokohama National University in Japan. They published their findings on October 27 in Scientific Reports, a Nature Research journal. (2020-12-07)

Drones and AI detect soybean maturity with high accuracy
Walking rows of soybeans in the mid-summer heat is an exhausting but essential chore in breeding new cultivars. Researchers brave the heat daily during crucial parts of the growing season to find plants showing desirable traits, such as early pod maturity. But without a way to automate detection of these traits, breeders can't test as many plots as they'd like in a given year, elongating the time it takes to bring new cultivars to market. (2020-12-07)

A related article appears in Astronomy & Astrophysics. (2020-11-25)

Black, Hispanic adolescents significantly more likely to die by police intervention than whites
A recent study evaluating the use of force by police against children found that Black and Hispanic adolescents are significantly more likely to die from shootings related to police intervention compared to non-Hispanic white adolescents. The findings, led by Children's National Hospital researchers and reported online Nov. 24 in Pediatrics, mirror similar racial and ethnic disparities in adults and highlight the need for interventions and policies to mitigate these tragedies.

To evade humans, this medicinal plant has evolved to hide in plain sight
Researchers reporting November 20, 2020 in the journal Current Biology have found that, in places where the herb is harvested more, the plant has evolved to blend in better with the background, making them harder for people to find. As a result, the plant varies in color from brown or grey to green, depending on whether it lives in a place that is frequented by human collectors or not. (2020-11-23)

Science reveals secrets of a mummy's portrait
How much information can you get from a speck of purple pigment, no bigger than the diameter of a hair, plucked from an Egyptian portrait that's nearly 2,000 years old? Plenty, according to a new study. Analysis of that speck can teach us about how the pigment was made, what it's made of - and maybe even a little about the people who made it. (2020-11-20)
