Cows go through puberty, and they're full of emotions, according to new study

Prior studies have shown that cows use different moos to express different feelings. And it turns out, they go through a lot of different feelings when they're going through puberty.


A new study published in the journal Royal Society Open Science sought to improve cattle farming practices by uncovering more information on the personalities of dairy cows at different points in their lives. "Our study identified a period of inconsistency in personality traits over puberty," Nina Von Keyserlingk, a professor of animal welfare at the University of British Columbia in Canada, told the Guardian. Cows experience mood swings from changing hormones, just like human teenagers.

Researchers corralled cows at the ages of one month, three months, one year, and two-and-a-half years, and observed their behaviors in a test area. Researchers looked at how cows changed their behavior when introduced to new people and things. They found that cows have pretty stable personalities in childhood and adulthood, which is consistent with prior studies. The teenage years are a different story.

At around 12 months, the cows became teenagers and behaved like it. Some days, hormonal cows feel shy and just want to be left alone. On other days, they'll nuzzle up to humans as if they weren't just a hormonal monster. Some cows became attention-seeking, and others grew solitary. Researchers believe that the changes in personality were caused by puberty hormones.

Once the cows started lactating, they chilled out and grew out of whatever phase they were going through.

Prior studies have found how the feelings of cows affect milk production. Stressed cows tend to eat less, grow slower, and produce less milk. They also have weaker immune systems. By learning how the personalities of cows shift in puberty, scientists hope they will have more insight into how to improve animal health and farming practices.

"Our overall goal is to improve the lives of animals on farms," Heather Neave, who worked on the study, told the Guardian. "Ideally, in the future, management practices would be tailored to the individual rather than the herd, so that all calves and cows have an opportunity to thrive on the farm and reach their full productive potential."

So if you visit a farm and see one cow standing in the corner, writing in its journal and blasting angsty music, just know that it's going through a phase.

Who would have thought that giving the world access to all human knowledge via the internet, the ability to follow and hear from experts on any subject via social media, and the ability to see what's happening anywhere in the world via smartphones with cameras would result in a terrifying percentage of the population believing and spouting nothing but falsehoods day in and day out?

Those of us who value facts, reason, and rational thought have found ourselves at some of our fellow citizens and thinking, "Really? THIS is how you choose to use the greatest tool humanity has ever created? To spew unfounded conspiracy theories?"

It's a marvel, truly.

Between Coronavirus/Bill Gates/5G conspiracies and QAnon/Evil Cabal/Pedophile conspiracies, I thought we were pretty much full up on kooky for 2020. But apparently not. The massive fires up and down the West Coast have ignited even more conspiracy theories, some of which local law enforcement and even the FBI have had to debunk.

In 1945, the world had just endured the bloodiest war in history. World leaders were determined to not repeat the mistakes of the past. They wanted to build a better future, one free from the "scourge of war" so they signed the UN Charter — creating a global organization of nations that could deter and repel aggressors, mediate conflicts and broker armistices, and ensure collective progress.

Over the following 75 years, the UN played an essential role in preventing, mitigating or resolving conflicts all over the world. It faced new challenges and new threats — including the spread of nuclear weapons and other weapons of mass destruction, a Cold War and brutal civil wars, transnational terrorism and genocides. Today, the UN faces new tensions: shifting and more hostile geopolitics, digital weaponization, a global pandemic, and more.

This slideshow shows how the UN has worked to build peace and security around the world:

It sounds like a ridiculous, sensationalist headline, but it's real. In Cheshire County, New Hampshire, a transsexual, anarchist Satanist has won the GOP nomination for county sheriff. Aria DiMezzo, who refers to herself as a "She-Male" and whose campaign motto was "F*** the Police," ran as a Republican in the primary. Though she ran unopposed on the ballot, according to Fox News, she anticipated that she would lose to a write-in candidate. Instead, 4,211 voters filled in the bubble next to her name, making her the official Republican candidate for county sheriff.

DiMezzo is clear about why she ran—to show how "clueless the average voter is" and to prove that "the system is utterly and hopelessly broken"—stances that her win only serves to reinforce.

In a blog post published on Friday, DiMezzo explained how she had never tried to hide who she was and that anyone could have looked her up to see what she was about, in addition to pointing out that those who are angry with her have no one to blame but themselves:

Dear JK Rowling,

I am writing this letter to say a big thank you to you. You may think it strange that a gobby trans woman such as me would wish to thank you after all your recent transphobic outpourings, but let me explain…

I certainly don't thank you for your lengthy essay last month where you describe the abuse you have suffered (for which you have my sympathy) and in which you stated that you do not hate trans people, while at the same time peddling even more anti-trans mis-information. Sadly, your diatribe directly caused some trans children to self-harm and other to attempt suicide.
