New study shows ‘genetic underpinnings’ of bisexuality
University of Michigan findings show link to risk-taking
A new study conducted by University of Michigan researchers and published Jan. 3 in the journal Science Advances identifies genetic variations linked to human bisexual behavior and found that genetic characteristics associated with bisexuality are also linked to risk-taking behavior in males.
A statement released by the University of Michigan announcing the study says its findings may answer at least in part the longstanding question by evolutionary biologists of how the genes associated with same-sex behavior have persisted in humans because “same-sex sexual behavior does not result in offspring.”
The study was conducted by University of Michigan Professor and evolutionary biologist Jianzhi Zhang and co-author and U.M. graduate student Siliang Song.
“The U.M. researchers analyzed data from more than 450,000 participants of European ancestry in the United Kingdom’s Biobank database of genetic and health information,” the university’s statement says. “Participants responded to a questionnaire that included the question, ‘Would you describe yourself as someone who takes risks?’”
According to the university statement, “The U.M. analysis revealed that male heterosexuals who carry the genetic variants associated with bisexual behavior, which are known as BSB-associated alleles, father more children than average. Furthermore, men who describe themselves as risk-takers tend to have more children and are more likely to carry BSB-associated alleles.”
Alleles are said to be matching genes, one from a person’s biological mother and the other from the biological father.
The statement says the two researchers also analyzed and compared the genetic makeup of both bisexual behavior and exclusive same-sex behavior, which they list as eSSB.
“When they compared the genetic basis of bisexual behavior to the genetic basis of eSSB, they found them to be significantly different,” the statement continues. “They found that eSSB-associated genetic variants are correlated with fewer children, which is expected to lead to a gradual decline in their frequency over time,” it says.
“However, the authors stress that their study looks at the genetic underpinnings of same-sex sexual behavior and not the behaviors themselves, which are affected by both genetic and environmental factors,” says the statement. It says the authors point out that the proportion of UK Biobank study participants reporting same-sex sexual behavior has risen in recent decades, mostly likely due to societal acceptance toward same-sex behavior.
In their study, the authors estimate a person’s bisexual behavior is influenced by genetics at about 40 percent and by environmental factors by about 60 percent.
“In addition, the authors say their new results ‘predominantly contribute to the diversity, richness, and better understanding of human sexuality. They are not in any way intended to suggest or endorse discrimination on the basis of sexual behavior,’ they wrote,” the University of Michigan statement says.
But an article about the study in Science Magazine says scientists and experts in the field of genetics have had mixed reactions to the study, with some questioning its reliance on the data from the UK Biobank surveys and others expressing concern that its claim that bisexuality is linked to risk-taking could perpetuate longstanding bias against bisexuals and gay men.
The Science Magazine article reports that psychologist Michael Bailey of Northwestern University, who has studied factors that influence sexual orientation, believes the study is “based only on self-reported past sexual behavior of the UK Biobank participants, and not on other aspects of sexuality, such as sexual orientation or feelings.”
Other experts in the field of genetics and human behavior, however, believe the study sheds valuable light on the issue of bisexual and exclusive same-sex behavior.

Markwayne Mullin confirmed as next DHS secretary
Okla. senator to succeed Kristi Noem
The U.S. Senate confirmed Markwayne Mullin as the next secretary of Homeland Security on Monday, as the agency continues to grapple with what lawmakers have described as a “never-ending” funding standoff, with Democrats attempting to withhold funding from one of the nation’s largest and most costly agencies.
Mullin — a Republican senator from Oklahoma, former mixed martial arts fighter, and plumbing business owner — was confirmed in a 54–45 vote. Two Democrats — U.S. Sens. John Fetterman (D-Pa.) and Martin Heinrich (D-N.M.) — sided with Republicans in supporting his confirmation.
The new agency head is expected to follow the policy direction set by President Donald Trump, emphasizing stricter immigration enforcement. This includes proposals to support immigration agents at polling sites and to cut funding to so-called “sanctuary cities.”
Mullin replaces Kristi Noem, who was fired earlier this month following a widely scrutinized 2-day congressional hearing on Capitol Hill.
During the hearing, Noem faced intense questioning over her response to several crises, including the fatal shooting of two American citizens in Minneapolis by U.S. Immigration and Customs Enforcement agents, a $220 million border security advertising campaign that featured her on horseback near Mount Rushmore amid one of the largest federal workforce reductions in U.S. history, and the federal response to major natural disasters such as the July 2025 Texas floods and Hurricane Helene in 2024.
Noem had previously drawn criticism for a series of policy decisions in South Dakota that broadly focused on restricting the rights of LGBTQ individuals. In 2023, she signed House Bill 1080, banning gender-affirming medical care for transgender minors. She also signed legislation and executive orders restricting trans athletes’ participation in women’s sports, as well as the state’s “Religious Freedom Restoration Act,” which critics argued enabled discrimination against LGBTQ individuals. Additionally, the state canceled contracts related to LGBTQ support services — including suicide prevention and health care navigation programs‚ and later agreed to a $300,000 settlement with trans advocacy group, The Transformation Project.
Despite her removal from DHS, Noem will remain in the Trump-Vance administration as a special envoy for the “Shield of the Americas,” an initiative aimed at promoting U.S. influence in the Western Hemisphere, including efforts to counter cartel networks, reduce Chinese influence, and manage migration.
The new head of DHS has served in Congress since 2013, in both houses of the federal legislature. While in the Senate and a member of the Health, Education, Labor, and Pensions (HELP) Committee, Mullin has been a vocal critic of policies aimed at expanding LGBTQ inclusion. He led a group of lawmakers in urging the Administration for Community Living to reverse a rule requiring states to prioritize Older Americans Act services based on sexual orientation and gender identity, arguing the policy could have unintended consequences.
Mullin also makes history as the first Native American — and a citizen of the Cherokee Nation — to lead the Department of Homeland Security. He was also among the 147 Republicans who voted to overturn the 2020 presidential election results despite no evidence of widespread fraud, and was present in the U.S. House of Representatives chamber on Jan. 6.

Protesters say SAVE Act targets voters, transgender youth
Bill described as ‘Jim Crow 2.0’
Members of Congress, advocates, and people from across the country gathered outside the U.S. Capitol on Tuesday to protest proposed federal legislation that voting rights activists have deemed “Jim Crow 2.0.”
The Safeguard American Voter Eligibility (SAVE) Act would amend the National Voter Registration Act of 1993 to require in-person proof of citizenship for anyone seeking to vote in U.S. elections.
President Donald Trump has also pushed for the proposed legislation to include a section that would ban gender-affirming medical care for transgender minors, even with parental consent, and prohibit trans people from participating in school or professional sports consistent with their gender identity rather than their sex assigned at birth.
In addition to changing voter registration requirements, the bill would limit acceptable forms of identification to documents such as a birth certificate or passport — records that the Brennan Center for Justice estimates more than 21 million Americans do not have — effectively restricting access to the ballot. It would also ban online voter registration, DMV voter registration efforts, and mail-in voter registration.
A 2021 investigation by the Associated Press found that fewer than 475 people voted illegally or improperly, a tiny fraction of the estimated 160 million Americans who voted in the 2020 election.
Senate Minority Leader Chuck Schumer (D-N.Y.) spoke at the event.
“It will kick millions of American citizens off the rolls. And they don’t even require you to be told,” the highest-ranking Democrat in the Senate told protesters and reporters outside the Capitol. “If this law passes — and it won’t — you’re gonna show up in November … and they’ll say… sorry, you’re no longer on the voting rolls.”

He, like many other speakers, emphasized the bill in the context of American history, pointing to what he described as its racist roots and its impact on Black and brown Americans.
“I have called this act, over and over again, Jim Crow 2.0 … because they know it’s the truth.”
U.S. Sen. Alex Padilla (D-Calif.) was one of the lawmakers leading opposition to the legislation and spoke at the rally.
“It’s not just voting rights that are on the line — our democracy is on the line,” the California lawmaker said. “It’s not a voter I.D. bill. It’s a bait and switch bill.”
He added historical context, noting the significance of voting rights legislation passed more than 60 years ago. In 1965, Alabama civil rights activists marched to protest barriers to voter registration. Alabama state troopers violently attacked peaceful demonstrators at the Edmund Pettus Bridge in Selma, using tear gas, clubs, and whips against more than 500 — mostly Black — protesters.

“61 years ago — not to the day — but this week, President Lyndon Johnson came to the Capitol and addressed a joint session of Congress in the wake of Bloody Sunday and pushed Congress to pass the Voting Rights Act,” Padilla said. “61 years later, Donald Trump and this Republican majority wants to take us backwards. We’re not gonna let that happen.”
U.S. Sen. Ben Ray Luján (D-N.M.) also spoke, emphasizing that he views the effort as a Republican-led and Trump-backed attempt to restrict voting access, particularly among Black, brown, and predominantly Democratic communities.
“President Trump told Republicans when they were meeting behind closed doors that ‘The SAVE Act will guarantee Republicans win the midterms and ensure they do not lose an election for 50 years,’” Luján said. “The first time I think Donald Trump’s been honest … This voter suppression bill is only that. Taking away vote by mail? I hope my Republican colleagues from states that voted for Donald Trump or where vote by mail is popular have the courage and the backbone to stand up and say no to this nonsense, because their constituents are going to push back.”
U.S. Sen. Lisa Blunt Rochester (D-Del.) also spoke.
“Our Republican colleagues have already cut Medicaid, Medicare, people don’t know how they’re gonna be able to afford energy,” she said, providing context for the broader political moment. “We’re in the middle of a war that they can’t even get straight while we’re in it and don’t have a way to get out of it. And we are now faced with defending our democracy?”
She then showed the crowd something that she said has been with her throughout her political journey in Washington.
“I brought with me something that I carried on the day that I was sworn into the House of Representatives when I was elected in 2016, and I carried it with me on the day that I was sworn in as United States senator. And I also carried it with me when I was trapped up in the gallery on Jan. 6 and all I could think to do was pray … This document allowed my great great great grandfather, who had been enslaved in Georgia, to have the right to vote. We took this and turned it into a scarf. It is the returns of qualified voters and reconstruction code from 1867. This is my proof of what we’ve been through. This is also our inspiration.”

“I got to travel between the Edmund Pettus Bridge two times. And even as I thought about this moment, I recognized that while we wish we weren’t in it, while we don’t know why we’re in it, I do know we were made for it … So I came today to tell you that, um, just like the leader said, that he calls it Jim Crow 2.0. I call it Jim Crow 2.NO.”
Kelley Robinson, president of the Human Rights Campaign, the largest LGBTQ advocacy organization in the U.S., also spoke, highlighting the impact of the bill’s proposed provisions affecting trans people.
“This bill is not about saving America. This bill is about stealing an election. This bill is about suppressing voters,” Robinson said. “This bill not only tries to disenfranchise voters that deserve their right to vote, it also tries to criminalize trans kids and their families … It tries to criminalize doctors providing medically necessary care for our trans youth.”

The SAVE Act passed the U.S. House of Representatives on Feb. 11 but has not yet been considered in the U.S. Senate.

Idaho advances bill to restrict bathroom access for transgender residents
HB 752 passed in state House of Representatives on Monday
The Idaho House of Representatives passed House Bill 752 on Monday, a measure that would make it a crime for a person to use a bathroom other than the one designated for their “biological sex.”
The story was first reported by the Idaho Capitol Sun after the bill cleared the House.
House Bill 752 would make it a criminal offense — either a misdemeanor or a felony, depending on the number of prior offenses — for individuals who “knowingly and willfully” enter a bathroom or changing room designated for the opposite sex.
The bill would apply to public buildings, including government-owned spaces, and places of “public accommodation,” a category that includes private businesses.
According to the bill’s text, it would “prohibit a person from entering a restroom or changing room designated for the opposite sex; provide a penalty; provide exceptions; define terms; and declare an emergency and provide an effective date.”
A first offense would be a misdemeanor, punishable by up to one year in prison. A second or subsequent offense within five years would be a felony, punishable by up to five years in prison.
The bill passed in a 54–15 vote on Monday. Six Republicans broke with their party’s majority to join nine Democrats in opposing the measure.
The bill’s sponsor, state Rep. Cornel Rasor, a Republican from Sagle near the Washington-Idaho border, told House lawmakers that the legislation is intended to protect women and girls.
“It prevents discomfort and voyeurism escalation and assaults, while preserving single-user options and narrow exceptions so no one is denied access for emergency aid,” Rasor said.
State Rep. Chris Mathias, a Democrat from Boise, disagreed, arguing that the legislation would unfairly target transgender Idahoans.
“The truth of the matter is — and I know a lot of people don’t want to say it — but forcing people who don’t look like the sex they were assigned at birth, or transgender folks, to use other people’s bathrooms is going to put a lot of people in danger,” Mathias said.
The Idaho American Civil Liberties Union made a statement about the bill following its passage.
“Idaho lawmakers continue pushing these harmful, invasive bathroom laws, yet cannot present credible evidence that transgender people using gender-aligned bathrooms threaten public safety,” the Idaho ACLU said. “The bill does nothing to address real criminal acts, such as sexual assault or voyeurism, and disregards concerns from law enforcement about the burden enforcement would place on local resources.”
In addition to human rights advocates, who have spoken out against similar bills advancing in state legislatures across the country, Idaho law enforcement groups have also opposed the measure. They argue that the way the legislation is written would “pose significant practical enforcement challenges,” noting that officers are tasked with maintaining public safety — not conducting gender checks or policing bathroom access.
During a committee hearing last week, law enforcement representatives and several trans Idahoans testified that the bill would make many residents less safe.
“Officers responding to a complaint would be placed in the difficult position of determining an individual’s biological sex in order to enforce the statute,” Idaho Fraternal Order of Police President Bryan Lovell wrote. “In many circumstances, there is no clear or reasonable way for officers to make that determination without engaging in questioning or investigative actions that could be viewed as invasive and inappropriate.”
The Idaho Sheriffs’ Association requested that lawmakers amend the bill to require that individuals be given an opportunity to leave a bathroom immediately before facing potential prosecution.
The bill now heads to the Idaho Senate for consideration. To become law, it must pass both chambers and avoid a veto from the governor.
A separate bathroom bill, House Bill 607, which would be enforced through civil lawsuits, passed the House last month but has not yet received a committee hearing in the Senate.
