Mosquitoes see red, which may be why they find us so appealing
Mosquitoes not only see colors, but also prefer certain ones, such as the hues of human skin.
- Environment
Bees and butterflies struggle to find flowers in polluted air
Emissions from cars and trucks make it harder for insects to find flowers. That in turn reduces flower visits and pollination, a new study finds.
- Genetics
DNA in air can help ID unseen animals nearby
Analyzing these genetic residues in air offers a new way to study animals. It could give scientists a chance to monitor rare or hard to find animals.
- Environment
Leaky sewer pipes pollute urban streams and bays with drugs
Scientists find that leaking sewer pipes around Baltimore, Md., spew thousands of doses of medicines into the Chesapeake Bay and other waterways.
- Microbes
