30-somethings nudge U.S. birth rate off record low
With more people delaying parenthood thanks to increased access to reliable birth control and fertility treatments, older moms are having more babies.
Why it matters: Although it's become more common, getting pregnant at " advanced maternal age" isn't always easy.
By the numbers: The birth rate for teenagers and women in their early 20s dropped to record lows in 2024, as the birth rate for women over 30 rose, according to provisional CDC data released Wednesday.
Women aged 30-34 had a higher birth rate (95.4 per 1,000 women) than those in their late 20s (91.4).
Reality check: Although the number of overall births rose 1% from 2023 to 2024, that's an increase from the nation's lowest fertility rate in nearly a century.
The big picture: Since the first IVF baby was born nearly 50 years ago, we've made big breakthroughs in understanding and treating infertility — and giving people options if they choose to delay parenthood.
Egg freezing, in-vitro fertilization (IVF), intrauterine insemination (IUI) and even uterine transplants have become more common.
Plus, we have a better understanding of how lifestyle affects fertility in both men and women.
Today, many hopeful parents, especially those over 35, can have babies through medical advancements that seemed like science fiction a generation ago.
"Fertility declines with age, but 35 is not a cliff by any stretch," Emily Oster, an economist and bestselling author of pregnancy and parenting books, tells Axios.
"Plenty of people have kids in their late 30s, but it might take a little more work and you might want to be thoughtful about your timing," says Oster, who recently launched a "trying to conceive" (TTC) section on her ParentData website.
Knowing about fertility barriers ahead of TTC could encourage hopeful older parents to address a medical issue and/or freeze eggs for IVF early on — giving them a better shot at pregnancy.
Yes, but: Even with new fertility technology and planning ahead, infertility can't always be overcome.
Tips to getting pregnant
Here's what prospective older parents can do to learn whether they have fertility roadblocks — and get pregnant more easily when they're ready:
Track their cycle.
If women knew earlier whether they had a normal menstrual cycle, it could save them from finding out too late that they have a condition, such as endometriosis or PCOS, that can interfere with getting pregnant.
And being educated on when they ovulate could prevent hopeful moms from reaching a point where "they're now 34½ and realize, 'Oh, I was having sex at the wrong time for the last five months, and now I've lost five months of good fertility," Oster says.
Boost sperm health.

The Aging Brain: 6 Things You Should Be Doing to Slow Cognitive Decline
When it comes to healthy aging, we tend to focus a lot on body health by exercising and eating well. One thing you might not be thinking about is brain health. But you should be. Your brain runs the rest of your body, and as we age, it changes, too. Cognition declines over time due to several factors, including age-related structure changes, brain injuries or excess stress hormones. According to the Centers for Disease Control and Prevention, one in nine American adults over 65 report cognitive decline. "The parts of our brain that help with learning information and remembering can become smaller, and the brain can weigh less as we age," said Colleen Marshall, chief clinical officer for Two Chairs. Aging doesn't happen at the same rate for everyone, but we all experience it in one way or another. Focusing on brain fitness now may help you slow the change and ensure your brain stays sharp through the years. How to start nourishing your brain for healthy aging 1) Solve puzzles We'll start with the easiest strategy to integrate into your daily life: puzzles. Solving puzzles can benefit the brain in several ways, from improving memory to boosting problem-solving skills. "They may slow the rate of cognitive decline and how quickly the brain decreases in size as we age," Marshall said. A study published in the journal Neurology reported that playing games like checkers or completing jigsaw puzzles can delay the onset of Alzheimer's by about five years. Different research supports the idea that solving crossword puzzles or journaling can lower the risk of dementia. Experts suggest that puzzles help curb cognitive decline because they expand the brain's cognitive reserve, or the ability to solve and cope with problems. Activities to try include putting together jigsaw puzzles or solving other types of puzzles, such as Sudoku, crosswords, memory games and math problems. 2) Learn a new skill Like stimulating the brain by playing games or solving puzzles, learning a new skill has short-term and long-term advantages. By learning a new skill, you're strategically activating several parts of your brain simultaneously. You're also promoting neuroplasticity by creating new pathways and strengthening those connections as you continue honing the skill. It could be learning a new language, painting or trying out a new sport. Just make sure it's challenging or complex, and continue to practice for the best brain results.3) Prioritize sleep Sleep is one of the most important things you can do for your body. While I'm not saying there's a right or wrong way to sleep, research suggests that how much sleep you get and the quality of your sleep influence your risk for dementia. According to a study published in the Journal of Neuroscience, a single night of sleep deprivation can age your brain. A lot goes on in the brain while we sleep, including clearing out toxins and creating new neural pathways. If you don't get enough sleep, your brain doesn't have time to carry out these functions and cognition suffers. Establishing a bedtime routine can have a big impact on your sleep quality. From reading a book to practicing yoga before bed, integrating relaxation into your night can help boost your sleep. 4) Focus on your nutrition What you eat also will influence the rate of cognitive decline you experience as you age. Studies have found that people who follow the Mediterranean and MIND (Mediterranean Dash Intervention for Neurodegenerative Delay) diets tend to have fewer cognitive impairments and dementias compared to those following other diets. More research is needed to conclude why this is true. However, it might have something to do with the way those diets prioritize foods that protect the brain with anti-inflammatory and antioxidant properties. Read more: Master the Mediterranean Diet With the Help of These Tips and Recipes No matter if you choose to follow a strict diet or just improve your current meal rotation, you'll want to focus on improving your blood sugar and dropping high levels of LDL cholesterol to reduce your risk of dementia. Foods to incorporate into your diet for better brain health: Leafy greens like spinach, kale and lettuce Salmon Dark berries Nuts Greek yogurt Dark chocolate Green tea Vegetables like broccoli and carrots 5) Exercise Studies have found that following an active lifestyle is associated with lower cognitive decline over time. Your heart rate increases when you exercise, which increases blood flow to the brain. This can help spark new development of nerve cells, a process called neurogenesis. Exercise also promotes increased connections between cells, making the brain more adaptive. Generally, any exercise that's good for the body will also help the mind. It doesn't have to be lifting weights; walking, swimming and dancing also achieve the same results. Read more: How Exercise Helps Boost Your Memory-Brain Health as You Age6) Make connections with others Marshall pointed out that prioritizing high-quality relationships with others can benefit the brain. According to a meta-analysis of longitudinal cohort studies, limited or poor relationships were associated with cognitive decline. Prioritizing social contact is an essential part of aging well. Whether spending time with your family or putting yourself out there at your local community center, staying connected is an integral part of aging gracefully. Too long; didn't read? Our brains change as we age; there is no way around it. However, integrating any of these easy habits into your routine can help nourish and safeguard your brain for the future. There are also a few things you should avoid to keep your brain in top shape. Heavy cigarette smoking has been associated with cognitive decline in middle age. Marshall added that heavy drinking, poor diet and unmanaged high blood pressure can also negatively impact the brain as we age. Don't worry; there's still time to turn it around. Even if you smoke now, quitting has the potential to return your risk of cognitive decline to a level that's comparable to those who never smoked.

The reasons aren't fully clear, but overdose deaths are down in Kern, US
Overdose deaths, specifically from opioids, are on the decline across the nation and data from the Kern County Coroner's Office shows local deaths are down as well. According to KCSO, there were 189 fentanyl-related overdose deaths in Kern County in 2024, down from 297 in 2023, a roughly 36% decline. The decline is part of a broader trend nationally. Opioid overdose deaths declined sharply from 2023-2024, according to provisional data from the Centers for Disease Control and Prevention. According to the CDC, 48 states and the District of Columbia all saw decreases in overdose deaths from December 2023 to 2024, a 26% decrease nationwide. California's reported overdose deaths dropped by 24%, the most of any West Coast state. Only Nevada and South Dakota saw an increase in overdose deaths, both by less than 4%. It's not entirely clear what's driving the decline, and experts are pointing to a range of factors. "Over the past, I'd say this calendar year, we have seen an increase in the people who are coming into our treatment system," said Ana Olvera, an administrator with Kern Behavioral Health and Recovery Services. "More people have accessed our treatment system than in years past, even coming out of COVID, which is a good sign for us," Olvera said. The increased availability of treatment programs and the overdose reversal drug naloxone were likely contributors to the decrease, she said, as well as reduced stigma about seeking treatment. Olvera also pointed to the passage of Proposition 36, which increased penalties for certain crimes. "Just from that — working with the courts and people who are eligible for this program that have a treatment-mandated felony — we have seen an increase of folks who are eligible and who come into our system of care," Olvera said. BHRS and other health care providers have increased their treatment options, Olvera said. The county's 24-hour substances-use-disorder hotline, which helps connect people with treatment, has seen higher call volume over the years, she said. "The call center is how most people access treatment in our substance use system," Olvera said. The average number of calls has increased from 908 in the 2018-2019 fiscal year to 1,272 in 2023-2024. From July 2024 to April of this year, there were 1,061 calls. There's no doubt overdose deaths are dropping, but exactly why is still a matter of conjecture. The Opioid Data Lab at the University of North Carolina at Chapel Hill tracks information related to opioids and its researchers have said there's no single explanation for such a steep, nationwide decline in overdose deaths. "Ascribing a single national explanation for the drop in overdoses is not grounded in data," the lab said in a February analysis. Even with the large decline in deaths, the mortality rate from drug overdoses remains high, with most states still recording death rates higher than before the COVID-19 pandemic. Data from the CDC and the California Department of Public Health shows overdose deaths peaking in 2023 before dropping sharply in 2024. According to CDPH, Kern County's opioid-related overdose deaths reached an all-time high of 321 in 2023. That was up from 308 in 2022 and 274 in 2021. As of April 30, Kern had seen 50 fentanyl-related deaths so far this year, according to KCSO.

Why RFK Jr.'s Purge Of Vaccine Advisors May Increase Your Health Costs
U.S. Health and Human Services Secretary Robert F. Kennedy Jr. speaks alongside President Donald ... More Trump during a press conference in the Roosevelt Room of the White House on May 12, 2025, in Washington, DC. (Photo by) News that U.S. Health and Human Services Secretary Robert F. Kennedy Jr. is making changes to how vaccines are approved could mean higher costs for what Americans pay for seasonal flu shots, childhood vaccinations and other vaccines to prevent illness. Kennedy, who has a history of hostility toward vaccines and has promoted conspiracy theories, earlier this week took the unprecedented step of removing all 17 members of the influential Advisory Committee on Immunization Practices, or ACIP. ACIP's recommendations are critical in deciding whether millions of Americans receive vaccines at no cost to them as part of their private insurance, Medicare or Medicaid coverage. The panel's recommendations are taken into consideration by the U.S. Centers for Disease Control and Prevention Director, or HHS Secretary, who 'can choose not to adopt an ACIP recommendation, to modify it, or to make their own recommendations and, in most, but not all cases, the HHS decision ultimately determines whether coverage is required,' KFF said in an analysis released Friday. 'Almost all payers are required to cover recommended vaccines at no-cost,' Jennifer Kates, KFF's senior vice president and director of global health & HIV policy wrote in the analysis. 'If ACIP or CDC vaccine recommendations were to be narrowed or removed, as was recently done in the case of COVID-19, most payers would no longer be required to provide no-cost coverage.' Kennedy has begun to appoint replacements for the 17 members he removed, but public health experts and physicians are concerned. The American Medical Association, for example, issued a rare rebuke of a sitting HHS Secretary regarding Kennedy's actions toward ACIP during the AMA's annual House of Delegates meeting earlier this week in Chicago. Kennedy began appointing new ACIP members, including some who have "criticized vaccines and spread misinformation," the Associated Press reported. These new members drew even more criticism. 'The AMA is deeply concerned to learn that new members have already been selected for the Advisory Committee on Immunization Practices (ACIP) without transparency and proper vetting to ensure they have the expertise necessary to make vaccine recommendations to protect the health of Americans,' AMA president Dr. Bobby Mukkamala said. 'We urge the (Trump) administration to reconsider the removal of the 17 ACIP members who have deep expertise in vaccines so physicians can continue to have confidence in ACIP's recommendations, which have for decades helped them make recommendations to patients about vaccination. We will closely monitor the developments of ACIP and encourage the Administration to recommit to maintaining vaccine access for all Americans.'
