New in EHP: Ubiquitous plastic additive DEHP alters sexual behavior in mice

Though you may have never heard of DEHP, it's the most common phthalate on the planet, used to make plastics in consumer products, packaging, and medical devices more flexible or durable. DEHP represents more than a third of the global plasticizer market and has been detected in more than 75% of analyzed individuals in industrial countries. It's also a known endocrine disruptor. The combination points to a potentially significant impact on public health that researchers are just beginning to understand. One area that has received particular interest is reproductive health. A new study in EHP offers intriguing evidence of a link with altered courtship behavior in otherwise healthy adult male mice via a reduction in the number of androgen receptors in the brain. I wrote a news story on the new research for EHP, which you can find here.

FOUR articles in the latest Chinese edition of Environmental Health Perspectives

The latest issue of EHP's Chinese edition, published this month, includes among its ten features and news articles no fewer than four by me, including this piece on mitigating the health effects of hot days, this one on what we know (but mostly don't know) about the human health effects of neonicotinoid pesticides, this feature on the ethics and efficacy of different approaches to protecting populations from environmental pollutants, and this feature on NIEHS-led research into environmental factors in breast cancer. It's great to know that the science I've covered in these various articles for EHP will become accessible to a vast new readership through the Chinese edition.

THREE articles in the December issue of Estuary News: aging stormwater pumps, post-fire watershed management, and intermittent-stream research

Proud to have three articles in the great new issue of Estuary News, ranging in length from short and sweet (a piece on the aging, often overwhelmed pump stations that keep Bay Area streets dry -- or at least try -- all winter long, and in some cases during dry weather, too) to a bit more in-depth (an article describing differing approaches toward erosion control and runoff management on undeveloped upper-watershed lands after a fire) and even meatier (a short feature on some interesting research along a 2.5-mile stretch of Coyote Creek in Morgan Hill's Henry W. Coe State Park -- which so happens to be my favorite Bay Area state park).

New in EHP: Health effects of manure irrigation

Farmers in Wisconsin and in many other states are increasingly embracing the practice of manure irrigation to fertilize their fields. Spraying liquid manure on fields offers multiple environmental benefits, but it may also pose a threat to the health and well-being of people nearby. In a new study in Environmental Health Perspectives, a team of Wisconsin researchers estimated the risk of acute gastrointestinal infection associated with this emerging exposure pathway to potentially harmful pathogens. ... Read the rest of my article here.

Architects of Metabolism: New in CNR's Breakthroughs mag

In the current (Fall 2017) issue of Breakthroughs magazine, I have a story on recent and ongoing research by College of Natural Resources professor Andreas Stahl and UC Berkeley colleagues into human metabolism. They're interested in how medical science may be able to harness it in the fight against the obesity epidemic. I won't go into too much more here, but the science is pretty fascinating  -- and if I did my job, you'll think so too. Read the 1,500-word story here.

New article in EHP: Developing the Science of Nature as a Public Health Resource

Two years ago I wrote a full-length feature for Environmental Health Perspectives on the connection between parks, nature, and human health. As the story showed, we know there's a link, but we can't say much conclusively about why or how, exactly, parks, nature, and other outdoor experiences (or their analogues) benefit health.

My latest Science Selection for EHP takes on the topic again, reporting on a new multidisciplinary commentary out of the University of Washington (led by accomplished environmental-health expert Howard Frumkin) assessing what we know and what we don't while proposing an exhaustive research agenda to guide the field as it matures.

Unwell: The Public Health Implications of Unregulated Drinking Water

Roughly one in seven U.S. residents relies on a private well for drinking water. Unlike the rest of the population served by the nation’s many public water systems, these 44.5 million Americans are not protected by the federal Safe Drinking Water Act, which regulates 87 biological and chemical contaminants. This has significant implications for public health, according to the authors of a new review in Environmental Health Perspectives, and although solutions exist for ensuring that well water is safe to drink, it is unclear how and whether they can be implemented.

Announcing AcclimateWest and my story on sea-level rise and the flood-prone, low-income San Rafael Canal district

Proud to announce the official launch (albeit still in pilot form) of a new multimedia journalism initiative I'm involved in along with some colleagues from Estuary News magazine, called AcclimateWest. This is a storytelling hub for sea-level rise adaptation around San Francisco Bay that will develop a series of iterative place-based profiles of waterways and creek mouths ringing the bay. 
In particular it has a strong environmental justice component and seeks to highlight impacts on vulnerable populations while using simple language designed to reach these very communities, rather than simply the usual audience of planners, politicians, scientists, and environmentalists. We built this simple, friendly, independent site to help local readers and residents connect with and understand how they may be affected by a rising bay and increased flooding, and what many local agencies and nonprofits are doing to prepare for it. Our stories revolve around specific places and assume our readers know little about the advancing ocean. 
The project is seeking additional funding to expand to other waterways, but my initial story on looming flooding impacts throughout the San Rafael Canal district, home to Latino immigrants and one of Marin's poorest and densest neighborhoods, is available now. Read "Canal Communities, Rich and Poor, Prep for Wetter Feet" here
My San Rafael story is a "baseline anchor story” for the Canal district. We need additional help to spread the word, create similar anchor stories for other waterways (including finding $3,000 in funding for each), and develop local advisory committees to ground our stories in local views and priorities. See the AcclimateWest website for more.

New in Estuary News: Choice Mountain Parcels Help Preserve the Bay

How is the bay connected with the hills and the mountains that surround it? Through creeks and streams, most of which begin as rainfall in the upper watershed. While these flows are heavily managed today, with reservoirs, weirs, flood-control channels, and other elements of modern infrastructure intervening, in some key ways they still perform much as they always have, delivering freshwater to the bay's estuaries while providing valuable aquatic and riparian habitat along the way. as they twist and tumble downstream.
All of which is to day that upper-watershed lands ringing the bay are valuable not only in and of themselves, but also because of their broader function in regional ecosystems -- which explains why they represent a key target for conservation groups throughout the greater Bay Area.

Who was Georg Steller and why are that jay and sea lion named after him?

In the Oct-Dec issue of Bay Nature: 
That crested camp-robber eyeing your pretzels, all squawk and blue feathers, is known as a Steller’s jay. And the Steller sea lion, quite vocal in its own right, is a larger, rarer cousin of Pier 39’s infamous California sea lion. Both the bird and the sea lion are native to the West Coast and named for Georg Wilhelm Steller, an 18th-century German botanist, zoologist, physician, and explorer.
