A new study has found that a man’s likelihood of being gay is determined by biological factors that occurr in the womb, CNN reports.

Researchers from Brock University, the University of Toronto, and Harvard Medical School published their results in the journal PNAS on Monday. Their findings indicate that when a woman gets pregnant with her first boy she builds an antibody against a Y-protein, NLGN4Y, which women do not have and that is part of male brain development. The mother builds a supply of the antibody, which can enter her bloodstream, and can cross the placental barrier into the brain of the next male fetus she carries.

“That may alter the functions in the brain, changing the direction of how the male fetus may later develop their sense of attraction,” lead study author Anthony Bogaert from Brock University says.

For every older brother a man has his chance of being gay goes up a third, even if the brothers are raised in separate households, according to the research. 

“This explanation posits that some mothers develop antibodies against a Y-linked protein important in male brain development, and that this effect becomes increasingly likely with each male gestation, altering brain structures underlying sexual orientation in their later-born sons,” the study authors write.

The study, which was started in 1996, tested the blood of 142 women and 12 men ages 18 to 80. Researchers found a high concentration of antibodies to the protein NLGN4Y, and the highest concentration of antibodies to the protein in women with gay younger sons and older brothers compared to women who only gave birth to heterosexual boys or no boys.

Bogaert emphasizes that the study isn’t suggesting gay men have a brain defect but is suggesting that humans are born with attractions from birth.

“The vast majority of men with older brothers are still heterosexual, but it says something very broad about sex and gender development,” Bogaert says.

Colombians protest against Trump after he threatened country’s president

Tens of thousands protested the US president in Bogotá

BOGOTÁ, Colombia — Tens of thousands of people on Wednesday gathered in the Colombian capital to protest against President Donald Trump after he threatened Colombian President Gustavo Petro.

The protesters who gathered in Plaza Bolívar in Bogotá held signs that read, among other things, “Yankees go home” and “Petro is not alone.” Petro is among those who spoke.

The Bogotá protest took place four days after American forces seized now former Venezuelan President Nicolás Maduro and his wife, Cilia Flores, at their home in Caracas, the Venezuelan capital, during an overnight operation.

The Venezuelan National Assembly on Sunday swore in Delcy Rodríguez, who was Maduro’s vice president, as the country’s acting president. Maduro and Flores on Monday pleaded not guilty to federal drug charges in New York.

Trump on Sunday suggested the U.S. will target Petro, a former Bogotá mayor and senator who was once a member of the M-19 guerrilla movement that disbanded in the 1990s. Claudia López, a former senator who would become the country’s first female and first lesbian president if she wins Colombia’s presidential election that will take place later this year, is among those who criticized Trump’s comments.

The Bogotá protest is among hundreds against Trump that took place across Colombia on Wednesday.

Petro on Wednesday night said he and Trump spoke on the phone. Trump in a Truth Social post confirmed he and his Colombian counterpart had spoken.

“It was a great honor to speak with the president of Colombia, Gustavo Petro, who called to explain the situation of drugs and other disagreements that we have had,” wrote Trump. “I appreciated his call and tone, and look forward to meeting him in the near future. Arrangements are being made between Secretary of State Marco Rubio and the foreign minister of Colombia. The meeting will take place in the White House in Washington, D.C.”

Kennedy Center renaming triggers backlash

Artists who cancel shows threatened; calls for funding boycott grow

Efforts to rename the Kennedy Center to add President Trump’s name to the D.C. arts institution continue to spark backlash.

A new petition from Qommittee , a national network of drag artists and allies led by survivors of hate crimes, calls on Kennedy Center donors to suspend funding to the center until “artistic independence is restored, and to redirect support to banned or censored artists.”

“While Trump won’t back down, the donors who contribute nearly $100 million annually to the Kennedy Center can afford to take a stand,” the petition reads. “Money talks. When donors fund censorship, they don’t just harm one institution – they tell marginalized communities their stories don’t deserve to be told.”

The petition can be found here.

Meanwhile, a decision by several prominent musicians and jazz performers to cancel their shows at the recently renamed Trump-Kennedy Center in D.C. planned for Christmas Eve and New Year’s Eve has drawn the ire of the Center’s president, Richard Grenell.

Grenell, a gay supporter of President Donald Trump who served as U.S. ambassador to Germany during Trump’s first term as president, was named Kennedy Center president last year by its board of directors that had been appointed by Trump.    

Last month the board voted to change the official name of the center from the John F. Kennedy Memorial Center For The Performing Arts to the Donald J. Trump And The John F. Kennedy Memorial Center For The Performing Arts. The revised name has been installed on the outside wall of the center’s building but is not official because any name change would require congressional action. 

According to a report by the New York Times, Grenell informed jazz musician Chuck Redd, who cancelled a 2025 Christmas Eve concert that he has hosted at the Kennedy Center for nearly 20 years in response to the name change, that Grenell planned to arrange for the center to file a lawsuit against him for the cancellation.

“Your decision to withdraw at the last moment — explicitly in response to the Center’s recent renaming, which honors President Trump’s extraordinary efforts to save this national treasure — is classic intolerance and very costly to a non-profit arts institution,” the Times quoted Grenell as saying in a letter to Redd.

“This is your official notice that we will seek $1 million in damages from you for this political stunt,” the Times quoted Grenell’s letter as saying.

A spokesperson for the Trump-Kennedy Center did not immediately respond to an inquiry from the Washington Blade asking if the center still planned to file that lawsuit and whether it planned to file suits against some of the other musicians who recently cancelled their performances following the name change. 

In a follow-up story published on Dec. 29, the New York Times reported that a prominent jazz ensemble and a New York dance company had canceled performances scheduled to take place on New Year’s Eve at the Kennedy Center.

The Times reported the jazz ensemble called The Cookers did not give a reason for the cancellation in a statement it released, but its drummer, Billy Hart, told the Times the center’s name change “evidently” played a role in the decision to cancel the performance.

Grenell released a statement on Dec. 29 calling these and other performers who cancelled their shows “far left political activists” who he said had been booked by the Kennedy Center’s previous leadership.

“Boycotting the arts to show you support the arts is a form of derangement syndrome,” the Times quoted him as saying in his statement.
