From Molecules to Organisms: Structures and Processes
- Chemistry
Light could make some hospital surfaces deadly to germs
A new surfacing material can disinfect itself. Room lighting turns on this germ-killing property, which could make the material attractive to hospitals.
- Animals
Cool Jobs: Diving for new medicines
Scientists mix research with underwater adventure as they search the oceans for new chemicals to treat infections, cancer and more.
- Life
This power source is shockingly eel-like
The electric eel’s powerful electric charge inspired this new squishy, water-based new approach to generating power.
- Health & Medicine
Obesity makes taste buds disappear — in mice, anyway
Mice that gained excessive weight on a high-fat diet also lost one in four taste buds.
- Climate
Analyze This: Climate change could make food less healthy
Levels of important nutrients are lower in crops exposed to high levels of carbon dioxide, a greenhouse gas. How high? Try levels expected to be typical 30 years from now.
- Animals
Explainer: DNA hunters
Snippets of DNA can be left behind by a passing organism. Some researchers now act as wildlife detectives to identify the sources of such cast-off DNA.
- Health & Medicine
Explainer: What is a concussion?
A concussion is a severe type of head injury that can damage a brain for weeks to years — perhaps even a lifetime.
- Agriculture
Explainer: The fertilizing power of N and P
Two elements — nitrogen and phosphorus — help plants grow. When the soil doesn’t have them, farmers might add them in the form of fertilizer.
- Genetics
Explainer: Why scientists sometimes ‘knock out’ genes
How do we learn what a particular molecule does in the body? To find out, scientists often 'knock out' the gene that makes it. Here’s how.
- Health & Medicine
Explainer: What is a hormone?
Various tissues secrete special chemicals, known as hormones. They travel, usually in blood, to a particular distant site where they tell certain cells it’s time to go to work.
- Physics
Disabilities don’t stop these experts in science and tech
People with disabilities are as varied as the careers some of them pursue in science, technology, engineering and math.
- Genetics
Explainer: How CRISPR works
Scientists are using a tool called CRISPR to edit DNA in all types of cells.
