This heat map shows what women experience when they walk home alone at night

February 15, 2024

In the United States, gender gaps remain firmly ingrained in the culture —whether it’s salary, time spent on household chores, or just feeling safe. Indeed, fully 85% of men report feeling safe when walking alone at night, compared to 64% of women, reveals Fast Company.

Now, a new study published in the journal, Violence and Gender suggests that this fear translates to significant behavioral differences between men and women.

Researchers at Brigham Young University, George Washington University, and University of Utah School of Medicine analyzed data from 571 college students at Brigham Young—56% female and 44% male. The students were asked to fill out a survey on walking home and safety.

The researchers gave the students 16 pictures of different locations at different points in the day and asked them to picture walking alone through the picture. The students were then asked to click the ar

eas of the picture that stood out most to them, creating a heat map.

The researchers found stark differences based on gender. Men tended to focus on walkways while women tended to focus on what surrounded the path, such as bushes or dark areas. This was particularly true at night. But even when there were lighted paths, women still focused on areas around the path.

“Despite attempts to improve environment, such as lighting; it is likely these findings represent a more systematic problem, rippling into other areas of women’s lives,” the researchers wrote.

“The results presented here can be a useful conversation starter for recognizing different lived experiences and to begin reclaiming everyday spaces for free mobility.”

Alzheimer’s blood test could hit the market early in 2024

December 7, 2023

Could a simple blood test detect Alzheimer’s disease years before symptoms appear? New research from Resonant—a Utah-based biotech company that develops diagnostic tests for neurodegenerative diseases—suggests it may be possible, reports the New York Post.

Researchers said its new test achieved 100% accuracy in identifying patients with Alzheimer’s disease and individuals with mild cognitive impairment (MCI) who went on to develop Alzheimer’s disease within five years.

In the study, a total of 50 blood plasma samples were tested. These included 25 older control individuals, 13 patients who had been diagnosed with Alzheimer’s, six patients with mild cognitive impairment who later developed Alzheimer’s, and six mild cognitive impairment patients who did not develop Alzheimer’s.

The findings were published in Frontiers in Neurology on October 31.

The blood test works by detecting the presence of DNA released from the brain’s neurons—or nerve cells when they die—according to lead researcher Chad Pollard, a doctorate student and research assistant at Brigham Young University.

“All cells, to some degree, release fragments of DNA called cell-free DNA (cfDNA) into their environment,” Pollard, who is also a co-founder of Resonant, told Fox News Digital in an email.

“Under normal, healthy conditions, cfDNA from neurons is undetectable in blood circulation, but during neurodegeneration, the amount of cfDNA that is released from these cells significantly increases and can be detected in the blood.”

The presence of neuron cfDNA in the blood indicates neurodegeneration, Pollard added.

Beyond Alzheimer’s disease, the researchers are also actively working to apply this technology to other neurodegenerative diseases, including Parkinson’s disease and amyotrophic lateral sclerosis (ALS, also called Lou Gehrig’s disease), noted Pollard.
