The San Francisco-based Breast Cancer Fund has just released some provocative data on the presence of bisphenol A — a hormone-mimicking pollutant — in every brand-name canned food it tested.

A major pollution-mapping program that ends September 9 has turned up startling trends in climate-warming gases and soot.

My daughter is always shopping for 4-inch heels or other elevating footwear to make her appear taller. But a new study suggests that diminutive stature has at least one major perk: a lower risk of cancer.

On April 2, for the fifth time in less than three years, the International Space Station fired its engines to dodge a piece of orbital debris that appeared on a collision path. Other spacecraft also regularly scoot out of the way of rocket and satellite debris. Such evasive action will be needed increasingly frequently, a new study finds.

“Sack” lunches often pose a ticking bacterial bomb, a new study indicates. And including an ice pack or two — ostensibly to keep perishables at safe temperatures — won’t necessarily eliminate the risk.

In June, scientists predicted that the Gulf of Mexico’s annual dead zone — a subsea region where the water contains too little oxygen to support life — might develop into the biggest ever. In fact, that didn’t happen. Owing to the fortuitous arrival of stormy weather, this year’s dead zone peaked at about 6,800 square miles, scientists reported on Aug. 1 — big but far from the record behemoth of 9,500 square miles that had been mentioned as distinctly possible.

The Environmental Protection Agency solicited public comment, July 26, about whether to require new toxicity testing and environmental sampling of bisphenol A, an ingredient in many plastics and food-contact resins.
