Pollen can become bee ‘junk food’ as CO2 rises
Increasing levels of the greenhouse gas are changing diminishing the food value of pollen, bees’ only source of protein.

This microbe thinks plastic is dinner
The bacterium Ideonella sakaiensis chows down on one type of polluting plastics. That means it could become helpful in cleaning up environmental waste.

Cool Jobs: Mapping the unknown
Scientists find different ways of exploring places humans will never visit — and drawing maps to help us better understand such mysterious places.

Carbon dioxide could explain how geysers spout
A new study overturns 150 years of thinking about Yellowstone’s geysers. Carbon dioxide, not just hot water, may be driving those spectacular eruptions.

Particles in air help fatten clouds’ water droplets
Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

Quake risk in some central states rivals California’s
Risks of tremors in some central U.S. states are as high as those in quake-prone California. The reason: waste fluids from oil and gas drilling.

Smash hit: Making ‘diamond’ that’s harder than diamonds
Scientists had suspected extreme meteorite impacts might turn graphite into an unusual type of diamond. Now they’ve seen it happen — in under a nanosecond.

Breathing very dirty air may boost obesity risk
Breathing dirty Beijing air made rats heavier and less healthy than rats breathing clean air. Scientists now worry such polluted air may do the same thing to people.

Microbes mine treasure from waste
Like miniature factories, bioreactors house microbes recruited to chew through wastes to clean dirty water, make chemicals or generate electricity.

Not so sweet: Fake sugar found at sea
Sucralose — sold in stores as Splenda — has begun turning up in seawater. This raises concern about the fake sweetener’s impacts on the environment.

Eggshells help hatch a new idea for packaging
Why just crack an egg? Make the shell into itty bitty bits and use them to build a more biodegradable plastic. New research shows how.

Enormous natural-gas leak polluted L.A. air
A massive methane release from a single leaky underground well spewed as much of the greenhouse gas into the air as a mid-sized European country does in an entire year.
