Entire galaxies feel the heat from newborn stars: Bursts of star birth can curtail future galaxy growth
(Phys.org) —Astronomers using the NASA/ESA Hubble Space Telescope have shown for the first time that bursts of star formation have a major impact far beyond the boundaries of their host galaxy. These energetic ...
Computer simulations show evolution of birds' crouch likely due to increase in forelimb size (w/ video)
Researchers use Moore's Law to calculate that life began before Earth existed

Early birds had four wings, not two, study reports
Some primitive birds boasted four wings, before evolution led them to ditch their hind feathers in favor of webbed or scaly feet, scientists in China said on Thursday.
Digging yields clues: Biologists connect burrowing behavior in mice to genes
Nature vs. nurture has long been one of the great debates in science—is behavior hard-wired into the brain, or determined by environment? In at least some cases, Harvard researchers are showing, how animals ...
Fluctuating environment may have driven human evolution
A series of rapid environmental changes in East Africa roughly 2 million years ago may be responsible for driving human evolution, according to researchers at Penn State and Rutgers University.
Magnesium oxide: From Earth to super-Earth
The mantles of Earth and other rocky planets are rich in magnesium and oxygen. Due to its simplicity, the mineral magnesium oxide is a good model for studying the nature of planetary interiors. New work from ...
Small lethal tools have big implications for early modern human complexity
On the south coast of South Africa, scientists have found evidence for an advanced stone age technology dated to 71,000 years ago at Pinnacle Point near Mossel Bay. This technology, allowing projectiles to ...
Dark matter filament studied in 3-D for the first time
(Phys.org)—Astronomers using the NASA/ESA Hubble Space Telescope have studied a giant filament of dark matter in 3D for the first time. Extending 60 million light-years from one of the most massive galaxy ...
Developmental biologist proposes new theory of early animal evolution, challenges basic assumptions
A New York Medical College developmental biologist whose life's work has supported the theory of evolution has developed a concept that dramatically alters one of its basic assumptions—that survival is based on a change's ...
