Moths wired two ways to take advantage of floral potluck | UW Today

Moths wired two ways to take advantage of floral potluck | UW Today | Science&Nature | Scoop.it

Moths are able to enjoy a pollinator’s buffet of flowers – in spite of being among the insect world’s picky eaters – because of two distinct “channels” in their brains, scientists at the University of Washington and University of Arizona have discovered.
One olfactory channel governs innate preferences of the palm-sized hawk moths that were studied – insects capable of traveling miles in a single night in search of favored blossoms. The other allows them to learn about alternate sources of nectar when their first choices are not available.

Why do we forget names?

Why do we forget names? | Science&Nature | Scoop.it

A reader, Dan, asks “Why do we forget people’s names when we first meet them? I can remember all kinds of other details about a person but completely forget their name. Even after a lengthy, in-depth conversation. It’s really embarrassing.”

Fortunately the answer involves learning something fundamental about the nature of memory. It also provides a solution that can help you to avoid the embarrassing social situation of having spoken to someone for an hour, only to have forgotten their name.

To know why this happens you have to recognise that our memories aren’t a simple filing system, with separate folders for each kind of information and a really brightly coloured folder labelled “Names”.

Artificial Skin Sends Touching Signals to Nerve Cells

Artificial Skin Sends Touching Signals to Nerve Cells | Science&Nature | Scoop.it
Prosthetic limbs can restore an amputee’s ability to walk or grip objects, but they haven’t yet been able to restore a person’s sense of touch. Researchers at Stanford University have taken a step closer to this type of prosthetic by creating an electronic skin that responds to pressure changes and transmits signals via nerve cells, much as human skin does.

Zhenan Bao and coworkers made the artificial skin by connecting three components: microstructured resistive pressure sensors, flexible printed organic electronic circuits, and nerve cells containing light-activated ion channels

The shape of a pipe dramatically affects how pollutants will spread | EurekAlert! Science News | Science&Nature | Scoop.it
The shape of a pipe has a large effect on the spreading of particles suspended in the fluid flowing through the pipe. Calculations show that round pipes produce symmetrical spreading along the flow direction, whereas rectangular pipes give an asymmetry.

Hubble Observes One-of-a-Kind Star Nicknamed ‘Nasty’

Hubble Observes One-of-a-Kind Star Nicknamed ‘Nasty’ | Science&Nature | Scoop.it
Astronomers using NASA’s Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy. In fact, the star is so weird that astronomers have nicknamed it “Nasty 1,” a play on its catalog name of NaSt1. The star may represent a brief transitory stage in the evolution of extremely massive stars. First discovered several decades ago, Nasty 1 was identified as a Wolf-Rayet star, a rapidly evolving star t
