Uranium in mine dust could dissolve in human lungs
New Mexico contains hundreds of historic uranium mines. Although active uranium mining in the state has ceased, rates of cardiovascular and metabolic disease remain high in the population residing close to mines within the Navajo Nation. According to a new study in ACS’ journal Environmental Science & Technology Letters, inhaled uranium in dusts from the mines could be a factor.


Paving the way for more efficient hydrogen cars

Dec 7, 2018 — American Chemical Society


Hydrogen-powered vehicles emit only water vapor from their tailpipes, offering a cleaner alternative to fossil-fuel-based transportation. But for hydrogen cars to become mainstream, scientists need to develop more efficient hydrogen-storage systems. Now, researchers reporting in ACS’ Chemistry of Materials have used metal–organic frameworks (MOFs) to set a new record for hydrogen storage capacity under normal operating conditions.

  Write with heat, cool and then repeat with rewritable paper  
The image on this cell phone case can change because it was made with rewritable paper.

Even in this digital age, paper is still everywhere. Often, printed materials get used once and are then discarded, creating waste and potentially pollution. Now, scientists report in ACS Applied Materials & Interfaces the development of an easy-to-make “rewritable” paper that can be drawn or printed on over and over again. The messages can last more than half a year, compared to other rewritable papers whose messages fade after a few days or a few months.


Why Antarctic fish don’t freeze to death (VIDEO)

Dec 6, 2018 — American Chemical Society

WASHINGTON—The notothenioid fishes that inhabit the Antarctic Ocean have evolved an unusual adaptation to living in icy waters.

Checking water quality at the tap
When consumers turn on a faucet, they expect the drinking water that gushes out to be safe. A new report in ACS’ journal Environmental Science & Technology found that U.S. public-supply tap water generally meets all enforceable standards. However, routine testing for most prospective contaminants is carried out before water is distributed, not where it’s used, and the report indicates some consumers are exposed to contaminant mixtures that aren’t commonly monitored.


What’s the difference between relative humidity and dew point?

Nov 30, 2018 — American Chemical Society

WASHINGTON—Meteorologists often report the amount of moisture in the air as relative humidity or dew point. These measures can be confusing to people who are just trying to determine if the weather outside will feel comfortable.
