From Molecules to Organisms: Structures and Processes
- Tech
How to make window ‘glass’ from wood
Scientists have come up with a way to make wood transparent. The new material could be used in everything from windows to packaging.
- Chemistry
Gotcha! New test stalks diseases early
Chemists screen blood for disease markers by adapting a common DNA test. The test can find disease earlier, when it also may be easier to treat.
- Fossils
How to tell if a T. rex is expecting
A chemical test of tyrannosaur bone can determine whether the dino was pregnant — and therefore a female.
- Genetics
Pacific islanders got a double dose of Stone Age DNA
Unlike other people, certain Pacific Islanders inherited DNA from two ancient human ‘cousins.’
- Genetics
Genes: How few needed for life?
Scientists rebuilt a microbe using its old genes. But not all of them. They used as few building-blocks as they could get away with and still have the life-form survive.
- Health & Medicine
Eating breakfast — even twice — is truly the healthier choice
Some experts argue that breakfast is the most important meal of the day — especially for keeping school-age kids at a healthy weight.
- Life
Fattier yeast live long and prosper
Scientists were hoping to build better biofuels. Instead they discovered that fatter yeast cells live longer than lean ones.
- Microbes
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.
- Animals
Spiders eat insects — and sometimes veggies
Plant-eating spiders have been found on every continent except Antarctica, a new study notes.
- Physics
Scrubbing bubbles: Secret to ouch-free dental cleanings?
People with sensitive teeth can find routine dental cleanings painful. But bubbles might pave way to no-touch — and pain-free — cleaning for these people.
- Animals
Cool Jobs: Pet science
Pets make great subjects for research. These scientists work to make our animals — and us — healthier and happier.
- Plants
Explainer: Some supplements may not have what it takes
Dietary supplements made from plants may not contain all of the chemicals that usually make a particular plant healthy for humans.
