We summarize the week's scientific breakthroughs every Thursday.

Superheavy element 117 makes debut
An international team of researchers fill a gap in the periodic table, and lay another stepping stone along the path to the “island of stability.”

Study reports hints of phthalate threat to boys’ IQs
You may have a hard time spelling phthalates, but there’s no avoiding them. They’re in the air you breathe, water you drink and foods you eat. And this ubiquity may carry a price, particularly for young boys, emerging data suggest. Including a drop in their IQ.
- Life
Researchers figure out how flies taste water
A study identifies the cell membrane protein that flies use to detect water’s flavor.
- Chemistry
Skin as a source of drug pollution
Traces of over-the-counter and prescription meds taint the environment. The presumption Ì and it's a good one Ì has been that most of these residues come from the urine and solid wastes excreted by treated patients. But in some instances, a leading source of a drug may be skin Ì either because the medicine was applied there or because people sweat it out.

Putting African sleeping sickness to bed
Experiments in mice find a protein that could lead to a safer and more effective treatment for parasitic disease.
- Chemistry
Mothballs deserve respect
I don’t use mothballs — except sometimes to sprinkle down the burrows of animals excavating tunnels beneath the deck floor of my pergola. It’s the most effective stop-work order for wildlife that I’ve found. But I won’t use these stinky crystals inside my home because they scare me. And those fears appear justified, according to Linda Hall of the California Environmental Protection Agency.
- Health & Medicine
Cap or cork, it’s the wine that matters most
Comparative study finds that screw tops can perform just as well in regulating the aging process.
- Health & Medicine
Walnuts slow prostate cancer growth
A new study suggests that mice with prostate tumors should say “nuts to cancer.” Paul Davis of the University of California, Davis, hopes follow-up data by his team and others will one day justify men saying the same.

Smokin’ entrees: Charcoal grilling tops the list
At the American Chemical Society meeting, earlier this week, I stayed at a hotel that fronted onto the kitchen door of a Burger King. This explained the source of the beefy scent that perfumed the air from mid-morning on – the restaurant’s exhaust of smoke and meat-derived aerosols. A study presented at the meeting confirmed what my nose observed: that commercial grilling can release relatively huge amounts of pollutants.
- Earth
Alternative flame retardants leach into the environment
Supposedly safer chemicals are spotted in peregrine falcon eggs in California.
- Chemistry
Building a cheaper catalyst
Using perovskite instead of platinum in catalytic converters could shave many hundreds of dollars off the cost of a diesel car.

The skinny on indoor ozone
Indoor concentrations of ozone tend to be far lower than those outside, largely because much gets destroyed as molecules of the respiratory irritant collide with surfaces and undergo transformative chemical reactions. New research identifies a hitherto ignored surface that apparently plays a major role in quashing indoor ozone: It’s human skin. And while removing ozone from indoor air should be good, what takes its place may not be, data indicate.
