"‘It breaks my heart.’ Trump cuts to Harvard leave Boston’s vulnerable sweltering without AC." Read the Boston Globe story featuring Dr. Adamkiewicz and Dr. Rice discussing impacts to their research aimed at helping Boston communities cope with heat and pollution. www.bostonglobe.com/2025/07/30/m...

#ClimateChange both worsens wildfires and increases negative health impacts caused by wildfire smoke. “Normally, immune cells are highly regulated, but after smoke exposure, some of those cells began to behave abnormally — to be hyperactivated," - Dr. Abhinav Kaushik, told the Harvard Gazette.

High risk patients in Black/Latinx communities have lower cancer screening rates but a new AI tool may be able to make screening more accessible. Dr. David Christiani explains for @fastcompany.com that these advances could help reduce cancer's impact on mortality. buff.ly/d7eqy37

New research from Dr. Marc Weisskopf shows how waste from the Manhattan Project may have led to higher cancer rates in a St. Louis community. “The closer the childhood residence got to Coldwater Creek, the risk of cancer went up, and pretty dramatically," Dr. Weisskopf told @wsj.com. buff.ly/BbiY90I

New Research from Dr. Kari Nadeau and @lafirehealth.bsky.social has shown that urban wildfires increase lead exposures for first responders. An @LATimes.com reporter decided to test his blood to see what type of impact the fires posed to residents.

The Nurses Health Study has pioneered women's health advancements for nearly 50 years, but this landmark study is threatened by federal funding cuts. @CNN.com spoke with study participants who are concerned that their scientific contributions will be lost. buff.ly/Vn0eQ4e

Funding cuts pose risks to over 50 years worth of biobank data in the Nurses' Health Study, investigated by Drs. Francine Laden, Jaime Hart, Peter James, and Marc Weisskopf. The Harvard Gazette explains that this groundbreaking study needs long-term funding solutions.

This morning on Good Morning America, Dr. Kari Nadeau discussed results from her new study in @natmed.nature.com‬ looking at how wildfire smoke affects firefighters. She found that toxins from smoke can penetrate into cellular DNA. See more on ABC News tonight at 7p. abcnews.go.com/GMA/News/vid...

Extreme heat worsens air quality. “Air pollution is very harmful for respiratory and cardiovascular admissions and also stroke. Those together can further enhance cardiovascular and respiratory risk.” says Dr. Mary Rice for @nytimes.com.

🏫 Pollutants are prevalent in our schools. They can enter through outside air or contaminants present inside building materials. The polluted air can be particularly harmful to children. The good news is polluted air in schools is fixable, says ‪@joeallenjoe.bsky.social‬. shorturl.at/As4MB

A new study co-authored by Dr. Peggy Lai and @joeallenjoe.bsky.social‬ revealed that improvements in one's gut microbiome can protect from harms of air pollution. "Our study shows that air pollution changes the tiny microbes in our gut,” said Dr. Lai‬. buff.ly/KMlW5DE

🍼🩺 Dr. Kari Nadeau shared with ‪@cnn.com‬ about her research funding being cut. "800 infants who had a high risk for a chronic disease...now have had a clinical trial pulled because of the lack of NIH funding...When that happens you put patients' lives at risk." Watch here: shorturl.at/MngVu

💨Scientists from the LA Fire HEALTH Study are committed to studying the impacts after the wildfires and giving residents the data in real time. Dr. Parham Azimi, a researcher at Harvard, is on site collecting air quality data from residents' homes. More in ‪@insideclimatenews.org‬ shorturl.at/u21KR

A new paper in Epidemiology shows that exposure to lingering pollution from wildfires can increase cardiovascular health risks, even months after the fires have been put out. The study was co-authored by Drs. Joel Schwartz, Edgar Castro and others at Harvard Chan. Read more: shorturl.at/2PPVE

How big of a threat to public health are the recent federal funding cuts? Dr. Marc Weisskopf, who conducts research on ALS in veterans explains on @cnn.com how the recent grant terminations are a big set back for public health. Watch: app.frame.io/presentation...

“Mitigating climate change would have huge benefits for reducing deaths and economic burdens from wildfire smoke,” stated Dr. Nick Nassikas for @thehill.com. Dr. Nassikas' new study found that climate change causes thousands of wildfire deaths each year.

Cuts in the NIOSH budget will cause a surge in silicosis, stated Dr. Gregory Wagner in a @theatlantic.com article. Cases will increase since NIOSH does not have the capacity to carry out research for implementing new prevention focused policy. www.theatlantic.com/ideas/archiv...

“Pregnant women and their fetuses are more vulnerable to climate-related changes, especially around heat and extreme heat,” stated @smahalingaiahmd.bsky.social‬ in a new TIME article about how climate change is impacting people’s ability to have healthy pregnancies: time.com/7285515/clim...

New research finds that eating an unhealthy diet in childhood may lead to earlier onset of periods in adolescence, explained @zifanwang.bsky.social in a new @CNN.com article. Early periods are on the rise, and have been connected to chronic health conditions. www.cnn.com/2025/05/06/h...
