Molecules/Matter & Energy
Marijuana loses its high, plus soy tape, gritty bubbles and more in this week’s news.
- Chemistry
Pesticides tied to lower IQ in children
Chemicals once sprayed in homes — and still used on farms — were found to have significant effects in three studies.
- Chemistry
Molecules/Matter & Energy
A quantum state is teleported, plus twisty light and foamy graphene in this week's news.
- Chemistry
Plants and predators pick same poison
Zygaena caterpillars and their herbaceous hosts independently evolved an identical recipe for cyanide.
- Chemistry
Molecules/Matter & Energy
3-D effects without the glasses, plus portable X-rays and linking qubits in this week’s news.

Fishy fat from soy is headed for U.S. dinner tables
Most people have heard about omega-3 fatty acids, the primary constituents of fish oil. Stearidonic acid, one of those omega-3s, is hardly a household term. But it should become one, researchers argued this week at the 2011 Experimental Biology meeting.
- Math
Cells take on traveling salesman problem
With neither minds nor maps- chemical-sensing immune players do well with decades-old mathematical problem, a computer simulation reveals.
- Humans
Record ‘Arctic’ ozone minimum expands beyond Arctic
In mid-March, our online story about the thinning of stratospheric ozone over the Arctic noted that conditions appeared primed for regional ozone losses to post an all-time record. On April 5, World Meteorological Organization Secretary-General Michel Jarraud announced that Arctic ozone had indeed suffered an unprecedented thinning. And these air masses are on the move to mid-latitudes.

A new way to fold a paper bag, plus good apples and designer silk in this week’s news.
- Humans
Hidden dalliance revealed by X-rays
A high-tech analysis uncovers a 19th century painter’s do-over.
- Humans
Just breathing in Iraq can be hazardous
Poor air quality is an added danger for troops, testing indicates.
