Thank you, 89.1 WEMU for the great conversation around increasing wildfires and our #lunghealth!

Canadian wildfires are impacting air quality in the U.S. Canada is having its second worst wildfire season yet. Two scientists explain what a red air alert means and how anyone living in impacted areas can protect themselves.

It was wonderful joining @npr.org 'Morning Edition' yesterday to talk about how the Canadian wildfires are impacting the air quality across American cities.

How Heat Waves Can Worsen Air Quality Scientists are increasingly concerned about the ways extreme heat and air pollution are linked.

Our planet's ever-increasing temperatures causes extreme weather – in all seasons! But these current heat waves not only feel unbearable, they also worsen our #airquality impacting those with respiratory conditions. nyti.ms/3TIh3rA

Musk’s AI ‘Colossus’ in Memphis Is Everyone’s Problem The tech CEO is skirting environmental protections in a predominantly Black community. But its residents aren't the only ones who will suffer.

🚩 Loopholes other manufacturers will use. The @selc.bsky.social took satellite images of the xAI facility. Photos revealed that instead of 15 turbines, xAI had quietly moved in at least 35 portable methane gas turbines, none of which had air quality permits.

It's not helpful to shame people with #autism or their families.

Comments such as “autism destroys families” have been received in sharply divisive ways.

It was never gone. We just stopped paying attention: The Resurgence of TB Tuberculosis helped to shape the field of pulmonary medicine. Why TB is reemerging in the US now and public health infrastructure is more important than ever.

In my latest AirWaves Substack, I explore why TB is resurging now, how the pandemic weakened global surveillance, and why underinvestment in public health puts us all at risk.

Research findings lead to future research that may save your or a loved one's life. I'm proud of our online medical community for continuing to advocate for continued research.

The more we know, the more we can do. 🥼

As a female leader in medicine, mentorship and trying to expand inclusivity within the medical field has always been rooted in a personal mission. Now, I'm reflecting what we should expect next.

Personal choice has been weaponized to undermine public health “Public health isn’t the sum of individual choices. It’s our collective agreement to protect the most vulnerable among us,” writes MeiLan Han.

We’re in a responsibility recession—not of personal responsibility, but of our shared responsibility to each other. My latest in STAT on what we’re losing when public health becomes personal choice. www.statnews.com/2025/04/08/m... via @statnews.com

Judge halts HHS plan to kill $11B in public health grants It's the latest move by a court to block recent actions by the Trump administration to abruptly cut off grant funding for public health.

NEW: A federal judge in Rhode Island froze a Trump administration plan to cut more than $11 billion in public health grants to state and local health departments that Congress allocated during the pandemic.

How Vaccine Backlash Gave Measles a Second Life Post-COVID vaccine backlash is reframing how we see preventable diseases—giving measles new ground and bringing with it a new threat: immune amnesia that leaves people vulnerable to new infections.

After COVID, many people have assumed herd immunity was out of reach for any virus. But measles isn’t COVID.

Do You Know the Warning Signs of Pulmonary Embolism? Symptoms can vary from subtle to severe, and knowing them could be lifesaving

A pulmonary embolism is not a joke.

Blood clots are linked to about 100,000 deaths annually, and pulmonary embolism, which restricts blood flow to the lungs, accounts for approximately half of them.

Thank you to @AARP for featuring this, bit.ly/3RujtsN.

HHS plans to shutter or downsize several health agencies, including at CDC Health and Human Services is planning to cut 10,000 jobs across the sprawling department.

#HHS announced today it plans to cut 10,000 full-time jobs across several agencies, as part of a broader effort by the Trump administration to restructure many parts of the federal government.

I will continue to pray that research can continue on.

It's #WorldTBDay and with the resurgence of #tuberculosis, I believe it is important to educate the public on: what it is, how it spreads, and treatment.

We Need More "Apple Watch Moments" Despite our current challenges, innovation remains a powerful tool for change. The Apple Watch is quietly transforming the detection of atrial fibrillation. How do we get more breakthroughs like this?

More and more of my patients have had their Apple Watch diagnose atrial fibrillation. It's not hype. It’s a quiet revolution in digital health. Why don’t we have more tech like this?

Hantavirus killed Gene Hackman’s wife, Betsy Arakawa. What is it? Betsy Arakawa died of hantavirus pulmonary syndrome at the age of 65, New Mexico health authorities said. Here’s what to know about the rare but deadly disease.

No one really talked about hantavirus until this past week...

In my book, Breathing Lessons: A Doctor's Guide to Lung Health, I discuss why reducing indoor pollution and airborne contaminates are important.

Some of the biggest breakthroughs in medical science came from women unafraid to enter #STEM spaces. I'm proud of the women who came before me, so I can be who I am professionally, and I look forward to seeing what the next generation can achieve. Happy #InternationalWomensDay.

They Worked to Prevent Death. The Trump Administration Fired Them. Now, the future of their public health missions is in question

- 750 workers at the CDC, which has a critical role responding to pandemics
- 1,000 at the NIH, which funds and conducts life-saving research
- Dozens at the Centers for Medicare & Medicaid Services
- Employees at the FDA, which oversees the safety of food, drugs, and med devices
