Chest pain could be a symptom of angina or a heart attack. Moyo Studio/E+ via Getty ImagesKeith Diaz, Columbia University For patients hospitalized with chest pain, the amount of time they spend sedentary afterward is linked to a greater risk for more heart problems and death within a year. That’s the key finding of a new peer-reviewed study my colleagues and I published in the journal Circulation: Cardiovascular Quality and Outcomes. We asked 609 emergency room patients experiencing chest pain — average age of 62 — to wear a physical activity monitor for 30 days after leaving the hospital. The monitor measured movements, sitting time and sleep throughout the day. We then followed patients for one year to track whether they had additional heart problems or died. We found that patients who averaged more than 15 hours of sedentary behavior daily — which does not include sleep — were more than twice as likely to experience more heart problems or die in the year after discharge than patients who accrued a daily average of 12 hours of sedentary time. But our goal wasn’t just to document that sitting is harmful. It was also to figure out what patients should do instead to lower their risk. We found that replacing 30 minutes of sedentary time with moderate or vigorous movement, like brisk walking or running, was most beneficial. It was associated with a 62% lower risk of experiencing more heart problems or dying in the year after discharge. But we also found that replacing 30 minutes of sedentary time with just light movement, such as slow walking or housework, lowered the risk of heart problems and death by 50%. Sleep was also a healthier option. Replacing 30 minutes of sedentary time with sleep lowered the risk of heart problems and death by 14%.Clogged arteries could lead to a heart attack.Veronica Zakharova/Science Photo Library via Getty Images
Why it matters
Over 8 million people in the U.S. are admitted to the hospital with chest pain suggestive of acute coronary syndrome. annually. This covers a range of conditions involving reduced blood flow to the heart, including angina and heart attack. Patients with acute coronary syndrome remain at high risk of having another heart problem even with optimal medical treatment. The risk also remains high for patients with chest pain who are discharged without a diagnosis of acute coronary syndrome, as their unexplained chest pain may be a precursor to more serious heart problems. Given this risk, there is a need to identify risk factors that can be modified to improve a patient’s prognosis after hospitalization for chest pain. In previous research, we found that patients with acute coronary syndrome had a fear of exercise and were sedentary, spending over 13 hours a day sitting. Given that sedentary behavior has been linked to poor heart health in the general population, we were concerned that patients were unknowingly increasing their risk of having another heart problem. Our latest findings confirm that sedentary time is a harmful behavior for these patients. But beyond telling patients to stop sitting so much, our work provides important guidance: Any movement, regardless of how intense, can be beneficial after hospitalization. This is especially relevant for people recovering from heart problems who may find exercise difficult or scary. While exercise provides the best “bang for your buck” in terms of health benefits, our findings are good news for patients who may not have the time, ability or desire to exercise. And for those unable to fit in more movement, just getting an extra half hour of sleep is a small, doable step that can make a meaningful difference for your health after hospitalization.
What still isn’t known
Researchers don’t fully understand why sedentary time is harmful. Muscles help regulate blood sugar and lipid levels. It is thought that when muscles aren’t used, such as when patients sit for hours, this can lead to harmful elevations in blood sugar and lipids. In turn, this can cause inflammation, plaque buildup in the arteries and organ damage. More research is needed to understand the biological mechanisms so that we can determine just how much movement is needed in a day.
What’s next
While our study highlights the potential risks of sedentary behavior after being hospitalized for chest pain, it was an observational study. Clinical trials are needed to confirm that replacing sedentary time with activity or sleep can improve prognosis.

Southwest Airlines is about to make the “airplane WiFi” experience feel a lot more like home.MAX Interior // Ashlee D. Smith
In a new announcement, Southwest Airlines Co. says it will begin rolling out Starlink ultra-fast inflight WiFi this summer. Starlink—engineered by SpaceX—will deliver next-generation connectivity across Southwest’s network of 11 countries, giving customers the ability to stream, scroll, share, and stay productive from takeoff to landing.
First Starlink-equipped aircraft launches this summer
Southwest says the first Starlink-equipped aircraft will enter service this summer, with a rapid integration plan behind it. By the end of 2026, Starlink WiFi is expected to be available on more than 300 aircraft.
The airline frames the rollout as a major step toward upgrading its fleet with high-speed, low-Earth-orbit satellite technology.
“An at-home experience in the air”
Southwest points to rising expectations around inflight connectivity—especially as travelers juggle work, entertainment, and messaging across multiple devices.
“Free WiFi has been a huge hit with our Rapid Rewards Members, and we know our Customers expect seamless connectivity across all their devices when they travel,” said Tony Roach, Executive Vice President, Chief Customer & Brand Officer at Southwest Airlines. “Starlink delivers that at-home experience in the air, giving Customers the ability to stream their favorite shows from any platform, watch live sports, download music, play games, work, and connect with loved ones from takeoff to landing.”
What Starlink brings to inflight internet
Starlink is described as a constellation of more than 9,000 satellites in low-Earth orbit. Southwest says the technology supports:
High-definition streaming and live gaming
Real-time messaging
Productivity tools, including the ability to collaborate and upload large files quickly
SpaceX also emphasized the goal of making inflight connectivity feel comparable to (or better than) home internet.
“We’re thrilled to deliver a connectivity experience to Southwest Airlines and its Customers that really is similar, if not better, than what you can experience in your own home,” said Jason Fritch, Vice President of Starlink Enterprise Sales at SpaceX. “Starlink is the future of connected travel, making every journey faster, smoother, and infinitely more enjoyable.”
Part of a broader cabin upgrade plan
Southwest notes it is currently the largest U.S. airline offering access to free WiFi fleetwide to loyalty members, thanks to T-Mobile (where available on WiFi-enabled aircraft). The Starlink rollout is positioned as one piece of a larger cabin refresh that includes:
Assigned and premium seating options
New aircraft seats made by RECARO
In-seat power at every seat, larger overhead bins, and seatbacks with a personal device holder
An Extra Legroom experience (Southwest says up to five additional inches compared to Standard and Preferred seats; seat pitch varies by aircraft)
Boarding process updates, including earlier boarding for Extra Legroom customers and select loyalty and credit card groups
Rapid Rewards tie-in
Southwest encourages travelers to join Rapid Rewards to unlock free WiFi and other benefits. The airline also notes members can purchase points to earn rewards and book destinations.

Early risers in Arizona are in for a celestial show.
On Tuesday, March 3, 2026, a total lunar eclipse will be visible across much of North America — including Phoenixand the Valley. During this event, the Moon will pass completely into Earth’s shadow, turning a deep copper-red color often called a “Blood Moon.”
Here’s what you need to know.
A schematic diagram of the shadow cast by Earth. Within the umbra, the central region, the planet totally shields direct sunlight. In contrast, within the penumbra, the outer portion, the sunlight is only partially blocked. Sun, Moon, and Earth sizes and distances between them not to scale.
🌍 What Is a Total Lunar Eclipse?
A total lunar eclipse happens when the Sun, Earth, and Moon align perfectly, with Earth positioned directly between the Sun and the Moon. As the Moon moves into Earth’s darkest shadow (the umbra), it doesn’t disappear — instead, it glows red.
That reddish color comes from sunlight filtering through Earth’s atmosphere — essentially, we’re seeing all the world’s sunrises and sunsets projected onto the Moon at once.
🕒 Phoenix Viewing Times (MST)
Arizona does not observe Daylight Saving Time in March, so these times are in Mountain Standard Time (MST).
The most dramatic portion — totality — lasts nearly one hour.
🌅 Where to Look in Phoenix
The eclipse happens in the pre-dawn hours, so the Moon will be low in the western sky as it sets.
For the best view:
Find a location with a clear western horizon
Avoid city light glare if possible
Consider desert viewpoints, parks, or elevated areas around the Valley
Because the Moon will be setting as the Sun begins to rise, the backdrop of early morning twilight could make for stunning photography.
🔭 Do You Need Special Equipment?
No.
Unlike a solar eclipse, lunar eclipses are completely safe to view with the naked eye. However:
Binoculars enhance color detail
A small telescope reveals subtle shadow gradients
A tripod and DSLR or smartphone with night mode can capture impressive images
🌎 Why This Eclipse Matters
This will be one of the most accessible celestial events of 2026 for Arizona residents. Total lunar eclipses don’t happen every year in the same location, and the timing — just before sunrise — adds dramatic visual contrast.
If skies are clear, Phoenix could have a spectacular view.
📌 Quick Viewing Reminder for Phoenix
Set your alarm for around 3:45 a.m.

Step outside by 4:00 a.m.
Look west
Watch the Moon turn red
No tickets. No crowds. Just the sky putting on a show.

Preparing Students: Automation, AI and societal economic changes are affecting the workforce and making a significant impact on the employment prospects of future generations. Consider this guidance to put students on the path toward greater earning potential and economic mobility in a rapidly changing economy.
(Family Features) Automation, AI and societal economic changes are affecting the workforce and making a significant impact on the employment prospects of future generations. More than one-third of today’s college graduates are “underemployed,” meaning they work jobs that don’t require a college degree and may pay less than a living wage, according to data from the Federal Reserve Bank of New York. At the same time, a World Economic Forum report explored how advances in AI are threatening to negatively impact access to entry-level and even mid-level jobs for millions of Americans. Looking ahead, research by Georgetown University indicates that by 2031, 70% of jobs will require education or training beyond high school. However, data from the National Center for Education Statistics indicate only one-third of high school graduates go on to complete a college degree with many of those being in fields that are not in high-earning, high-growth professions. These challenges are not lost on today’s students. In a survey by Junior Achievement and Citizens, 57% of teens reported AI has negatively impacted their career outlook, raising concerns about job replacement and the need for new skills. What’s more, a strong majority (87%) expect to earn extra income through side hustles, gig work or social media content creation. “To put students on the path toward greater earning potential and economic mobility in a rapidly changing economy, students need proactive education and exposure to transferable skills and competencies, such as creative and critical thinking, financial literacy, problem-solving, collaboration and career planning,” said Jack Harris, CEO, Junior Achievement. This assertion is consistent with findings from the Camber Collective. This social impact consulting group identified four key life experiences students can consider and explore that positively affect lifetime earnings, including:
Completing secondary education
Graduating with a degree in a high-paying field of study
Receiving mentorship during adolescence
Obtaining a first full-time job with opportunity for advancement
Students aiming to equip themselves with the skills and experience necessary for the future workforce can seek:
Learning opportunities that are designed with the future in mind. For example, learning experiences offered through Junior Achievement reflect the skills and competencies needed to promote economic mobility.
Internships or apprenticeships that provide hands-on experience and exposure to a career field that can’t be found in a textbook.
Volunteer or extracurricular roles that develop communication and leadership skills. Virtually every career field requires these soft skills for growth and greater earning potential.
Relationships that provide insight and connection. Networking with individuals who are already excelling in a chosen field, as well as peers who share similar aspirations, offers perspective from those who are where you wish to be and potentially opens future doors for employment.
Courses that offer introductory insight into a chosen career path. Local trade or technical schools and other training organizations may even offer certifications that align with a student’s area of interest.
