This image, taken with a powerful microscope,
shows tiny, individual crystals of bismuth telluride. A new structure
made from this material lets light travel easily and without
interruption along its surface.
Artists and scientists worked together to
create this sculpture that shows what Jane, a colonial American, might
have looked like. A study of the teen’s remains indicates she was
cannibalized after she died.
Adebola Duro-Aina (left), Oluwatoyin Faleke
(center) and Zainab Bello (right) designed a system that uses urine to
produce a fuel. Generators that run on this fuel, rather than gasoline,
would avoid spewing carbon monoxide, a toxic pollutant.
This map, from the United States Geological Survey, shows the age of
bedrock in different regions of North America. Scientists found ancient
water in bedrock north of Lake Superior. This region, colored red, was
formed more than 2.5 billion years ago.
Scientists recently used a computer program
to decode patterns of brain activity displayed during a dream. They
found that a certain object was linked with a particular pattern, and
that pattern was similar whether the object was seen while awake or
asleep.
A rat kidney was stripped of its cells and
repopulated with human and rat cells. Researchers transplanted the organ
into a rat, where it functioned to produce urine and filter impurities
from blood.
