Bighorn sheep are disappearing in Texas. Wildlife biologists are stepping in.
About 50% of the state's bighorn sheep population was decimated in the last five years due to disease, said Froylán Hernández of the Texas Parks and Wildlife Department. Hernández is the program leader for the department's Desert Bighorn Sheep Program.
The disease spread to the bighorn sheep from other animals, which people brought to the region. Bighorn sheep are native to the western mountains and were once revered by Native Americans.
Last fall, wildlife biologists planned a rescue. They captured dozens of bighorn sheep, some pregnant, from the only disease-free Texas herd left.
The biologists airlifted the sheep to veterinarians to ensure they were healthy, and then moved the sheep more than 200 miles to an isolated mountain range, free of disease-carrying species.
Biologists returned to the herd this month in the Franklin Mountains in West Texas to see if the sheep survived, and maybe if the herd grew. They found a line of nine sheep, including lambs that were just days old.
The Texas herd is growing again, and biologists hope it won't butt heads with humans or disease.
"I am extremely, extremely happy, very, very satisfied," Hernández said. "It's monumental."

Psychologist warns of withdrawal effects of cellphone ban in Texas schools
Move over, baseball. Like it or not, "scrolling" has become the nation's pre-eminent pastime. "Yeah, it's super tough," said Carly Decker in Dallas. "I'm personally glued to my phone because of various jobs, and all require I be on call at all hours. So, it is tough to find a balance." Texas lawmakers aim to reduce classroom distractions with a new law banning cellphones, tablets, and smartwatches during the school day. "I'm in agreeance with it," said Stephanie Paresky. "I think that they should not be in the classroom. They need to be focused on learning and not all the distractions." Paresky says her elementary school-aged child is still too young for a cellphone, and they are holding the devices at bay for as long as they can. Limited screen time is the norm for her family, but a glance around most public spaces shows that attitude is rare. "Four people can be having dinner... like out at a nice restaurant," said Josh Briley, Ph.D., a team lead psychologist at Parkland Health, "and all of them are on their phones. None of them are mindful, none of them are present in the moment." The anxiety associated with being without those devices has its name: nomophobia. Briley says it's not an official medical diagnosis, but he's warning parents and educators of the school day consequences of the ban. "There's going to be short-term implications with anxiety, depression, irritability, anger," said Briley, Ph.D., CCTP, FAIS. "Due to technological advances, we have become, as a society, very dependent upon our devices." Briley says parents will have a big impact on how well their students adjust to the change. "If the parents do nothing but complain about it and talk about the downside, then the student is going to be more resistant." He urges parents to lead by example—putting down their own devices. Begin to schedule "technology-free" time at home and during short car rides. And he says, don't forget to acknowledge the positives. "They will be less distracted in class, so they will be paying more attention," Briley said. "Their social skills will improve. They'll learn to talk to each other face to face, and have conversations that don't involve texting each other." Briley also reminds parents to acknowledge their own anxiety about not being able to reach students during the school day. He suggests reaching out to school administrators beforehand to learn about emergency contact protocols. "We miss so much in our children's lives when our noses are buried in our phones," shares Briley. "I'm not saying, 'don't ever use your phone'... but this is a good time for families to evaluate."

A massive US measles outbreak has slowed but the start of the school year brings renewed risk of spread
Texas hasn't reported a new outbreak-related measles case in nearly a month — a hopeful sign that one of the largest outbreaks the United States has seen in decades is starting to slow. But the measles threat hasn't faded as new outbreaks and growing case counts in other states add to the national tally. There have been more measles cases reported in the US in the past month – at least 89 confirmed cases since the start of July – than in most years since the disease was declared eliminated a quarter century ago, according to data from the US Centers for Disease Control and Prevention. And this year's total – 1,356 confirmed cases since January – is higher than it's been in more than 30 years. There have been 32 outbreaks this year, accounting for nearly 90% of all cases since January. Only 10 states remain at zero cases reported this year. The start of the school year in the US poses new threats for the spread of measles amid a record-breaking year for cases and lagging vaccination rates. Experts say that declining childhood vaccination rates across the US coupled with ongoing spread of measles in the US – and large outbreaks in neighboring Canada and Mexico – have raised concerns as children start to gather for the new school year. 'Nobody has a crystal ball, but the conditions are there to see an increased number of cases,' said Dr. Catherine Troisi, an infectious disease epidemiologist at UTHealth Houston. On Saturday, Wisconsin reported nine new cases – all linked to the same exposure during travel to another US state. The state health department isn't releasing more details about the cases – including the vaccination status of the individuals or the specific state they traveled to – in order to 'balance individual privacy for what the public needs to know' and because the risk of community spread is considered to be low, Dr. Ryan Westergaard, chief medical officer in the Wisconsin Department of Health Services Bureau of Communicable Diseases, said at a news briefing on Monday. But new data published by the CDC last week shows that kindergartners in Wisconsin had one of the lowest rates of coverage with the measles-mumps-rubella (MMR) vaccine. Only 84.8% of kindergartners had gotten the two recommended doses of the MMR vaccine last school year, well below the 95% threshold necessary to prevent an outbreak. Only Alaska and Idaho had lower MMR vaccination rates, the CDC data shows. 'Back-to-school brings a lot of kids together and measles is very, very infectious,' Troisi said. 'So if you bring kids together and one of them happens to have measles, that's just a great way to spread the virus.' Declining vaccination rates also leave more kids vulnerable, she said, including those who are not vaccinated, those who are vaccinated but immunocompromised and those who are too young to be vaccinated. 'If you have more kids at risk, then the chance of measles spreading increases,' she said. Wisconsin is one of just 15 states that allow parents to exempt their schoolchildren from required vaccines for 'personal conviction reasons,' in addition to religious beliefs or for medical reasons. There was a record rate of exemptions in the US last school year, CDC data shows, with about 3.6% of incoming kindergartners allowed to miss at least one required vaccine – and the exemption rate in Wisconsin was more than double that, at 7.6%. The American Academy of Pediatrics says that non-medical exemptions to school immunization requirements should be eliminated, a longstanding position that the organization recently reaffirmed. 'Exempting children for nonmedical reasons from immunizations is problematic for medical, public health, and ethical reasons and creates unnecessary risk to both individuals and communities,' AAP leaders wrote in a policy statement last month. 'Although there are certainly families who would value having the option to decline vaccines and also send their children to school, nonmedical exemptions threaten the safety of the entire school community and shift the burden of protecting their children to the parents of children who are medically fragile, immunocompromised, or unable to receive immunizations for medical reasons.' A new measles outbreak was announced in Michigan's Osceola County last week, with the original case resulting from an individual who was exposed to measles while traveling out of state. It's the third outbreak in the state, which has now reported at least 27 cases this year. Wyoming also reported a batch of new measles cases on Saturday: four new cases in Carbon County were exposed to an individual with a confirmed measles infection, bringing the state's total up to seven. Data from the Wyoming health department shows that Carbon County had some of the lowest vaccination rates among children in the state in 2023, ranking 21st out of 23 counties with just 66% of toddlers having gotten at least one dose of the MMR vaccine. 'County-level vaccination coverage estimates are important because public health issues often begin in small geographic areas and certain public health actions are most effective at the local level,' according to the Wyoming health department. Unvaccinated individuals tend to be geographically clustered within certain communities, experts say, as families with similar sociocultural beliefs often live near each other. 'This phenomenon results in a greater likelihood of disease outbreaks when a vaccine-preventable illness is introduced into these communities,' AAP leaders wrote in the policy statement. 'Outbreaks that start in communities with low vaccination coverage have the potential to spread beyond those communities into other communities with low vaccination coverage or into the broader population, particularly for diseases like measles, varicella, and pertussis.' While the start of the school year poses new risks, it also creates opportunities for trusted community leaders to encourage and promote vaccination, experts say. 'We do know that if vaccine clinics are held at schools, that will increase (coverage) just by making it easier for parents to get their kids vaccinated,' Troisi said. 'School nurses are respected, so having them talk about how important vaccines are is another strategy.'
