Cousins’s work, she says, “is really the tip of the iceberg.” Faust has found newer types of PFAS—ones that are not routinely monitored by the EPA—in US rainwater at higher concentrations than these legacy compounds (Environ. Sci.: Processes Impacts 2022, DOI: 10.1039/d2em00349j). The more scientists look, the more PFAS they seem to find.

“I think [Venclexta] is just the tip of the iceberg,” he says. AstraZeneca/Bristol Myers Squibb: Farxiga Hyperglycemia, or high blood glucose, is a manifestation of type 2 diabetes and over time can lead to serious health problems. The drug Farxiga (dapagliflozin) can help treat type 2 diabetes by inhibiting excess glucose from being reabsorbed from the kidneys into the blood, instead causing the glucose to be excreted into the urine.

But I’m sure this is the tip of the iceberg. Where did the Twitter hashtag #vidalized come from? #Vidalized came from Fraser Stoddart, actually. I did a postdoc with him, and he taught me that accuracy in figures is important; the publication stays forever. More recently, he told me about a retired professor at Emory University, Fredric Menger, who similarly pointed out errors in published data a few decades ago.

In ammonia and corn ethanol plants, for example, the gas exiting exhaust pipes is 80% or more CO2 and just needs to be dried and compressed for transport. As the CO2 in emissions gets more dilute, the energy required to extract it rises. The emissions coming from steel plants and many chemical processes tend to be between 15 and 80% CO2.

Whether this project succeeds or fails, Whitehead says she hopes to get across that this is the tip of the iceberg when it comes to unanswered questions about female biology. She also hopes to encourage more women to let personal experiences shape our pursuit of science. This diversity in thinking will lead to broader questions, more discovery, and, of course, more innovation.

Researchers have also designed tests that search for proteins in blood that are unique to the viruses scientists use to transport genes across a cell membrane and then into a genome (Drug Test. Analysis 2012, DOI: 10.1002/dta.1347). Other techniques rely on looking at the sugars decorating the protein that’s been produced from the contraband: For example, EPO is normally produced in the kidney, where it is glycosylated in four different places.

But the odors are just the tip of the iceberg: The compounds are also eye, skin, and lung irritants and potential carcinogens. Even so, the chemicals are critical to the production of polyurethane paints, coatings, adhesives, and foam insulation—some of the most useful materials ever invented. Nanotech Industries (NTI), based in Daly City, Calif., and its commercial arm, Hybrid Coating Technologies (HCT), received the Designing Greener Chemicals Award for creating the first polyurethanes that don’t need isocyanates in the production process.

Besides all the obvious issues surrounding the provision of transport for such a large population and keeping them employed, healthy, and fed, pollution problems are only likely to become exacerbated. Despite some commitment toward moving pollution-creating businesses out of the urban center, it is concerning that air and water quality do not appear to be high in the agenda for planners.

State Departments of Transportation (DOTs) have turned to cured-in-place pipe, or CIPP, as a fast and low-cost way to rehabilitate the aging systems. The technology repairs concrete or corrugated metal culverts by lining them with plastic pipe, a patch job that’s not without risks: When the liner is installed, it can unleash an initial flood of chemical contaminants into waterways that slows but continues to leach for weeks afterward.
