If you're in your mid-40s and haven't had your colon checked, it might be time.The American Cancer Society's newly updated guidelines for colon and rectal cancer screening recommend that adults at average risk get screened starting at age 45 instead of 50, as previously advised.The updated guidelines come on the heels of what seems to be a rise in colorectal cancer among younger adults.Those at higher risk include African Americans, Alaska Natives, and people with a family history or a personal history of colon or rectal polyps; risk factors such as these could require screening earlier.Published in CA: A Cancer Journal for Clinicians on Wednesday, the updated guidelines also indicate that there are six screening test options for adults, ranging from noninvasive stool tests to visual exams like colonoscopy, depending on the preference of the patient and availability of the test.Other health organizations in the United States -- such as the US Preventive Services Task Force -- still recommend routine screening for colon and rectal cancers starting at age 50. 1081

If you're interested in fish who are scary-looking, poisonous and chock-full of elaborate defense mechanisms, look no further than the stonefish, a genus of fish that populate coastal waters of the Indo-Pacific region.As if their deadly venom and spiny exteriors weren't enough, scientists at the University of Kansas have found that stonefish also have a hidden switchblade on their face that they can flick out whenever they feel like they're in danger.Scientists call the bony, blade-like protrusion a "lachrymal saber," because it is located on a bone under the fish's eyes. Also, "lachrymal saber" is just a really metal-sounding name.William Leo Smith, associate curator and associate professor of ecology & evolutionary biology at KU, first started to understand how the lachrymal saber worked 15 years ago, when he was dissecting a stonefish he kept as a pet.This is a game-changerHe tells CNN the mechanism isn't just a cool new discovery (although it's that, too). It also changes the scientific understandings and classifications of this particular type of fish."It opens up these ideas of ecological questions. Muscular systems, bone systems, nervous systems all came together to form this. What led to its evolution or use?In other words, he says, "Why do we see this accumulation of so many horrible things on one fish?"The lachrymal saber is housed inside the fish's head, and they use their cheek muscles to deploy it. Though some stonefish are venomous, the saber is not.It could be a sex thing, tooSmith says he and his fellow researchers have reason to believe the saber isn't just for warding off predators: It could be a sex thing, too."There is evidence pushing towards that," he says. "They may use this in battles with other members of their species, like ram horns. It may also be involved in courtship behaviors."Oh, and the sabers glow."It's fluorescent green," Smith says. Since stonefish rely on camouflage for both protection and hunting prey, Smith doesn't think the fluorescence has a defensive purpose like, say, warning off predators.There are 134 described species of stonefish, and by Smith's observation, all of them have some form of lachrymal saber.  2202

HOUSTON (AP) — A federal judge has extended the deadline for the release of migrant children from detention, as advocates for detained families feared the government would create what they called a new form of family separation. U.S. District Judge Dolly Gee in Los Angeles on Thursday granted a request for a 10-day extension to release children held in family detention centers longer than 20 days. In her ruling last month setting the Friday deadline, Gee said the family detention centers "are 'on fire' and there is no more time for half measures."According to NBC News, Gee stated back in June that COVID-19 had made detention centers unsafe.Gee's recent ruling did not extend to parents detained with their children, the Associated Press reported. 762

In a pair of 2015 speeches, President Donald Trump's nominee for a federal judgeship in Texas described transgender children as evidence of "Satan's plan," lamented that states were banning conversion therapy and argued that sanctioning same-sex marriage would lead to polygamy and bestiality.Jeff Mateer, the current first assistant attorney general of Texas, was serving at the time as general counsel of the First Liberty Institute, a religious liberty advocacy group known before 2016 as the Liberty Institute. He faced criticism from LGBT rights groups for his work with the organization, such as opposing the expansion of nondiscrimination protections to LGBT people in the city of Plano. If confirmed by the US Senate, he will serve on the US District Court for the Eastern District of Texas.In a May 2015 speech, titled "The Church and Homosexuality," Mateer discussed a Colorado lawsuit in which the parents of a transgender girl sued her school for preventing her from using the bathroom of her choice."In Colorado, a public school has been sued because a first grader and I forget the sex, she's a girl who thinks she's a boy or a boy who thinks she's a girl, it's probably that, a boy who thinks she's a girl," Mateer said in a video posted on Vimeo in 2015 and reviewed by CNN's KFile. "And the school said, 'Well, she's not using the girl's restroom.' And so she has now sued to have a right to go in. Now, I submit to you, a parent of three children who are now young adults, a first grader really knows what their sexual identity? I mean it just really shows you how Satan's plan is working and the destruction that's going on."Mateer's nomination comes as the Trump administration has unveiled a series of actions aimed at rolling back advancements for gay and transgender rights. Trump vowed to fight for the LGBT community during his presidential campaign and said last April that people should "use the bathroom they feel is appropriate." Since taking office, however, Trump has withdrawn an Obama administration directive that allowed transgender students in public schools to use the bathroom of their choice and issued a directive banning transgender military recruits.In that same May 2015 speech, Mateer said that the Supreme Court decision allowing same-sex marriage could lead to what he called "disgusting" new forms of matrimony."I submit to you that there'll be no line there," he said. "And actually in the arguments Chief Justice Roberts, who's in the center there said, I mean, what is the limiting? Why couldn't four 4 people wanna get married? Why not one man and three women? Or three women and one man? And we're gonna spare you some of those slides. We actually have a presentation that we get into it. And I'll tell you, we say it's PG-13, it may be R, or what do they call the next one? NC-17 or whatever?"He continued, "I mean, it's disgusting. I've learned words I didn't know. I mean, other than...my assistants here, have you ever heard the word 'throuple'?'Throuple' so that's three people coming together of different sexes, maybe mixed sexes. Them coming together. There are people who marry themselves. Somebody wanted to marry a tree. People marrying their pets. It's just like -- you know, you read the New Testament and you read about all the things and you think, 'Oh, that's not going on in our community.' Oh yes it is. We're back to that time where debauchery rules."Later that year in November 2015, Mateer lamented that states were banning gay conversion therapy at a conference hosted by controversial pastor Kevin Swanson, who preaches that the Biblical punishment for homosexuality is death."Biblical counselors and therapists, we've seen cases in New Jersey and in California where folks have gotten in trouble because they gave biblical counseling and, you know, the issue is always, it's same sex," Mateer says in audio obtained by CNN's KFile. "And if you're giving conversion therapy, that's been outlawed in at least two states and then in some local areas. So they're invading that area."Groups like the American Psychiatric Association and the American Pediatric Association have condemned the practice as having no scientific basis and the potential to do mental harm.Mateer did not respond to a request for comment. A Department of Justice spokesperson declined to comment on Mateer's remarks. 4371
