|
|

|
|
|
Built-in brain “templates” may clue tots to threats
Do babies know something about spiders before ever seeing one?
|
|
|
Sunless but livable planets may be detectable
They drift through deep space alone, studies suggest—lightless, but perhaps not lifeless.
|
|
|
What? Where? When? Some animals may know
New findings may bear on debates over whether animals are conscious.
|
|
|
How Roman farmers left their mark on nature
Recently unearthed, ancient settlements are found to have had surprising
effects on the landscape above.
|
|
|
Cops
racist in shooting? Not as much as many of us
A study has found little evidence that police shoot black people particularly
readily. But it did turn up a surprise.
|
|
|
Humiliation takes harsh health toll, report says
Past studies have looked at the health effects of social exclusion or
prejudice, but not those of outright debasement.
|
|
|
The
perks and pitfalls of pride
What is the origin and purpose of this complex emotion?
|
|
|
Dump the “ethnic cleansing” jargon, group implores
A team of scholars wants doctors and scientists to lead the world in consigning
the phrase “ethnic cleansing” to history.
|
|
|
Dolphin
braininess due to social life, studies suggest
Dolphins and their kin are widely thought to be among the cleverest creatures.
But what might have made them so?
|
|
|
What
is consciousness? Study aims to settle debate
Researchers also propose to subject claims of “out-of-body experiences”
to a strict test.
|
|
|
The
galaxy next door—our destined home?
New simulations predict what could happen when our galaxy, as expected,
runs into a neighboring one.
|
|
|
Ape facial expressions foster group harmony, study finds
Facial expressions may have evolved as a sort of social glue in our
ape-like ancestors, researchers say.
|
|
|
Human
evolution, radically reappraised
Our evolution has been speeding
up tremendously, a study contends.

Beyond a Galaxy's
Borders Normally, only the
bluish-pink central region of this spiral galaxy is visible. But this image, mapping radio emissions (shown as red)
and others alongside visible light, reveals the less apparent outlying
zones. The central pinwheel is known as the galaxy's main stellar disk, while the
reddish, ribbon-like structures are called its extended arms. Astronomers have been excited to find that clusters of baby stars match with the extended arms, because this helps them better understand how stars
form in a galaxy's "backwoods." The young stars are believed to extend
up to 140,000 light-years from the center. This composite image of the Southern Pinwheel galaxy, or M83,
was released April 16 by NASA's Galaxy Evolution Explorer mission
and the U.S. National Science Foundation's Very Large Array in New Mexico. (Credit: NASA/JPL-Caltech/VLA/MPIA).
