"This finding runs counter to the backlash effect typically found in impression management research in business settings," write the researchers. "Female job evaluations typically suffer after engaging in the same self-promoting impression management strategies that benefit their male counterparts."

Researchers sorting through muddy sediment in lakes of the Pacific Northwest find droughts match regional warming periods over the past 2,000 years. READ MORE…

Whiteners contain fluorescent materials that glow under violet and ultraviolet light. Sunlight, fluorescent light, and incandescent light all produce some light in the violet and ultraviolet range. The whiteners used in consumer products work under those conditions, resulting in a bright white perception. However, most current LED bulbs use blue LEDs to excite a phosphor that then glows white, but produces no violet or ultraviolet light. (Credit: huisman/Flickr)

For shades of white, LED bulbs need added violet

While some LED bulbs make colors pop, many may not showcase or differentiate the appearance of white products because all white light is not the same. READ MORE…

"This research is important because it confirms the resilience of African bees despite the heavy presence of recently introduced Varroa mites, and it suggests that the approach to manage these pests should not follow the application of pesticides as has been done in the western world," says Elliud Muli.

Brains don’t recover during football’s off-season

The off-season may not be long enough for the brains of football players to completely heal, resulting in a greater risk of head injury the next season. READ MORE…

Beyond learning more about the fly's wind-sensing capabilities, Sawyer Fuller says that this information will also help engineers design small flying robots—creating a sort of synthetic fly. "Our results suggest that little flying vehicles would also do well to have fast wind sensors to compensate for this delay." (Credit: John Tann/Flickr)

Fruit fly antennae kick in for ‘cruise control’

Scientists have discovered that fruit flies regulate their flight speed by using both vision and wind-sensing information from their antennae. READ MORE…

"The application of stretchable electronics to medicine has a lot of potential," says Yonggang Huang. "If we can continuously monitor our health with a comfortable, small device that attaches to our skin, it could be possible to catch health conditions before experiencing pain, discomfort, and illness."
