Birds' voiceboxes are odd ducks

Science News - Mon, 09/24/2018 - 5:45pm
Birds' voiceboxes are in their chests instead of their throats like mammals and reptiles. Scientists aren't sure how or why birds evolved these unique voiceboxes, but a new study sheds some light on how they came about. Similarities in the windpipes of birds, crocodiles, cats, mice, and salamanders suggest that birds' weird voiceboxes might have arisen from a windpipe reinforcement. From this, scientists can learn about the sounds bird ancestors -- dinosaurs -- made.

Common weed killer linked to bee deaths

Science News - Mon, 09/24/2018 - 5:45pm
Honey bees exposed to glyphosate, the active ingredient in Roundup, lose some of the beneficial bacteria in their guts and are more susceptible to infection and death from harmful bacteria. Scientists believe this is evidence that glyphosate might be contributing to the decline of honey bees and native bees around the world.

Wigner crystal -- not Mott insulator -- in 'magic-angle' graphene

Science News - Mon, 09/24/2018 - 5:44pm
Recently, scientists created a stir in the field of condensed matter physics when they showed that two sheets of graphene twisted at specific angles display two emergent phases of matter. After a careful review of the experimental data researchers say that the insulating behavior of the ''magic-angle'' graphene is not Mott insulation, but something even more profound -- a Wigner crystal.

How fruits got their eye-catching colors

Science News - Mon, 09/24/2018 - 5:44pm
New evidence supports the idea that plants owe their rainbow of fruit colors to the different animals that eat them. Researchers first had to get past the fact that most animals don't see colors quite the way humans do.

Doubts and dialogue may alter public perceptions of science

Science News - Mon, 09/24/2018 - 5:44pm
Science projects within controversial fields such as synthetic biology could benefit from experimenting with communication settings in which experts share their thoughts and feelings with each other and the public. This allows for a more open and constructive dialogue with the public about research - and may even generate new research ideas, new research suggests.

Sex in plants requires thrust

Science News - Mon, 09/24/2018 - 4:09pm
In plants, to fertilize the egg, the pollen tube (which is between 1/20 and 1/5 of the width of a human hair) has to navigate through a maze of tissue, no matter what obstacles it encounters. Thanks to the lab-on-a chip technology scientists were able to actually see and measure exactly what was going on within the pollen tube as it grew.
