Nothing Kills the Mood More for Women than Seeing a Guy Vomit
For women, disgust dampens sexual arousal more than any other emotion, even more than fear.

Researchers from the University of Portsmouth have found that disgust can be a bigger passion-killer for women than fear. The team was led by evolutionary psychologist Diana Fleischman, who explained the reason behind the study:
“Sexual arousal motivates us toward closeness with others and their bodies while disgust motivates us away. Given these competing motivations, every one of our ancestors had to overcome disgust in order to have sexual contact and reproduce.”
So, the question for women is which desire is more powerful?
To find out, the researchers gathered 76 heterosexual women to participate in the study (ages ranging from 18 to 42). They were exposed to one of the four following conditions outlined in the paper:
“...rate disgust stimuli then watch a pornographic clip; watch a pornographic clip then rate disgust stimuli; rate fear stimuli then watch a pornographic clip; or watch a pornographic clip then rate fear stimuli.”
It should be noted that the erotic clips were filmed by women and intended to be appealing to women. The fear images were pictures of violent people, dangerous animals, weapons, heights, tornados, and fire, while the disgust images were ones of diseased or injured humans and human corpses, feces, and people vomiting.
In order to measure arousal, the researchers used self-reporting as well as a vaginal insert — kind of like a tampon — called a photoplethysmograph. The device was used to measure blood flow to the vagina, which would indicate arousal (or lack thereof).
The researchers write of their results:
“Women who were exposed to disgusting images before erotic content showed significantly less sexual arousal than women in the control condition or women exposed to fear-inducing images before erotic content.”
This shows that, for women, disease avoidance trumps our reproductive instincts.
Many scientists wonder why we evolved to have sex and why it continues to be the popular mode of reproduction for humans. Bill Nye explains that there are many other safer and more advantageous ways to reproduce.

Explore how alcohol affects your brain, from the first sip at the bar to life-long drinking habits.
- Alcohol is the world's most popular drug and has been a part of human culture for at least 9,000 years.
- Alcohol's effects on the brain range from temporarily limiting mental activity to sustained brain damage, depending on levels consumed and frequency of use.
- Understanding how alcohol affects your brain can help you determine what drinking habits are best for you.
If you want to know what makes a Canadian lynx a Canadian lynx a team of DNA sequencers has figured that out.
- A team at UMass Amherst recently sequenced the genome of the Canadian lynx.
- It's part of a project intending to sequence the genome of every vertebrate in the world.
- Conservationists interested in the Canadian lynx have a new tool to work with.
If you want to know what makes a Canadian lynx a Canadian lynx, I can now—as of this month—point you directly to the DNA of a Canadian lynx, and say, "That's what makes a lynx a lynx." The genome was sequenced by a team at UMass Amherst, and it's one of 15 animals whose genomes have been sequenced by the Vertebrate Genomes Project, whose stated goal is to sequence the genome of all 66,000 vertebrate species in the world.
Sequencing the genome of a particular species of an animal is important in terms of preserving genetic diversity. Future generations don't necessarily have to worry about our memory of the Canadian Lynx warping the way hearsay warped perception a long time ago.

It is easy to see how one can look at 66,000 genomic sequences stored away as being the analogous equivalent of the Svalbard Global Seed Vault. It is a potential tool for future conservationists.
But what are the practicalities of sequencing the genome of a lynx beyond engaging with broad bioethical questions? As the animal's habitat shrinks and Earth warms, the Canadian lynx is demonstrating less genetic diversity. Cross-breeding with bobcats in some portions of the lynx's habitat also represents a challenge to the lynx's genetic makeup. The two themselves are also linked: warming climates could drive Canadian lynxes to cross-breed with bobcats.
John Organ, chief of the U.S. Geological Survey's Cooperative Fish and Wildlife units, said to MassLive that the results of the sequencing "can help us look at land conservation strategies to help maintain lynx on the landscape."
What does DNA have to do with land conservation strategies? Consider the fact that the food found in a landscape, the toxins found in a landscape, or the exposure to drugs can have an impact on genetic activity. That potential change can be transmitted down the generative line. If you know exactly how a lynx's DNA is impacted by something, then the environment they occupy can be fine-tuned to meet the needs of the lynx and any other creature that happens to inhabit that particular portion of the earth.
Given that the Trump administration is considering withdrawing protection for the Canadian lynx, a move that caught scientists by surprise, it is worth having as much information on hand as possible for those who have an interest in preserving the health of this creature—all the way down to the building blocks of a lynx's life.
The exploding popularity of the keto diet puts a less used veggie into the spotlight.
- The cauliflower is a vegetable of choice if you're on the keto diet.
- The plant is low in carbs and can replace potatoes, rice and pasta.
- It can be eaten both raw and cooked for different benefits.
