PALO ALTO, Calif., April 7 (UPI) — While the modern human genome features some Neanderthal DNA, new research suggests the Neanderthal equivalent of the modern male Y chromosome is no more. —> Read More
Government researchers are getting to the bottom of the sexist microaggressions women get from men in the engineering world.
Sexist migroaggressions can include sexual harassment, mansplaining, objectification, and stereotyping. According to the Washington Free Beacon, The National Science Foundation is planning a study that will track the ways in which male students exercise sexist behavior against their female peers. The study, which will be conducted at the University of Michigan, will videotape the interactions between male and female engineering students over the course of three years.
“Because engineering is cast as a masculine field, women engineering students can experience subtle yet pervasive stereotypic messages in their learning environments that can negatively influence their experiences,” states the grant for the study.
The study will be conducted in several stages, with the goal of finding out how migroaggressions affect performance and overall teamwork among male and female students. In addition to videotaping male and female students’ interactions, the study will also include focus groups where the students will be tested by watching videos with and without microaggressions and then figuring out solutions to prevent them.
Of course, while the study focuses on the engineering space, its findings might shed some light on larger problems for women in male-dominated fields, especially in STEM, where women make up just 24% of workers in science, tech, engineering and math fields, according to a 2011 study.
Finally, sciencesplaining for the mansplainers.

Shout it from the rooftops — America’s rooftop solar capacity could be double what scientists previously thought.
If Americans slapped solar panels on every flat, sunny rooftop in the country, the U.S. could satisfy nearly 40 percent of its total electricity demand from solar alone, according to a new study from the National Renewable Energy Laboratory.
Experts say the numbers reflect newer, better methods for calculating total solar potential.
“For figuring out technical solar potential, I think this is a very good study,” Mike Jacobs, senior energy analyst at the Union of Concerned Scientists, told The Huffington Post.
Researchers used sophisticated LiDAR technology to map the topography of 128 cities in the U.S. down to the square meter. Combining that data with estimates of solar capacity researchers were able to gauge the total rooftop space available for solar power production in the U.S.
Their findings estimate the “technical potential” of rooftop solar production in the U.S. to be 1,118 gigawatts of capacity, which amount to 39 percent of national electricity sales and is nearly double what previous studies estimated. The study also found that small buildings hold the greatest solar potential, accounting for 65 percent of potential rooftop solar capacity.
That doesn’t mean the U.S. will start generating nearly half of its electricity from rooftop solar panels, however. “Technical potential” refers only to what the U.S. could produce if every inch of suitable rooftop space were used for solar production, said Robert Margolis, senior energy analyst at NREL and co-author of the study. “It’s not necessarily what you would do economically,” Margolis told HuffPost.
Researchers counted only rooftops that receive enough sunlight to power solar panels efficiently. Rooftops blocked from the sun by trees or other obstructions, as well as north-facing rooftops, were ruled out. The study also didn’t —> Read More

When I was trained at a prominent New York medical center in the 1960s, cancer was relegated to a minor place in the curriculum. Cancer patients were housed in a separate hospital, rarely visited by students or the medical house staff. If not amenable to surgery or radiotherapy, most cancers were regarded as hopeless. Research on cancer was not accorded the attention received by infectious, endocrine, autoimmune, cardiovascular, or neuropsychiatric disorders.
