Opposite effect: Protein widely known to fight tumors also boosts cancer growth

Researchers studying p53, the heralded cancer-fighting 'guardian of the genome,' found that the human protein also plays a role in promoting tumors, in addition to suppressing them. They found that the PUMA protein works inside the cell's mitochondria to switch energy production processes and stimulate cancer growth.

Hubble fortuitously discovers a new galaxy in the cosmic neighborhood

Astronomers using the NASA/ESA Hubble Space Telescope to study some of the oldest and faintest stars in the globular cluster NGC 6752 have made an unexpected finding. They discovered a dwarf galaxy in our cosmic backyard, only 30 million light-years away.

European waters drive ocean overturning, key for regulating climate

An international study reveals the Atlantic meridional overturning circulation, which helps regulate Earth's climate, is highly variable and primarily driven by the conversion of warm, salty, shallow waters into colder, fresher, deep waters moving south through the Irminger and Iceland basins. This upends prevailing ideas and may help scientists better predict Arctic ice melt and future changes in the ocean's ability to mitigate climate change by storing excess atmospheric carbon.

New 3D printer shapes objects with rays of light

A new 3D printer uses light to transform gooey liquids into complex solid objects in only a matter of minutes. The printer can create objects that are smoother, more flexible and more complex than what is possible with traditional 3D-printers. It can also encase an already existing object with new materials, which current printers struggle to do.

To sleep, perchance to heal: Newly discovered gene governs need for slumber when sick

Humans spend nearly one-third of their lives in slumber, yet sleep is still one of biology's most enduring mysteries. Little is known about what genetic or molecular forces drive the need to sleep -- until now. In a study of over 12,000 lines of fruit flies, researchers have found a single gene, called nemuri, that increases the need for sleep.

Earth's largest extinction event likely took plants first

New evidence from the cliffsides of Australia suggests that Earth's largest extinction event -- a volcanic cataclysm occurring roughly 252 million years ago -- extinguished plant life long before many animal counterparts.

Learning new vocabulary during deep sleep

Researchers showed that we can acquire the vocabulary of a new language during distinct phases of slow-wave sleep and that the sleep-learned vocabulary could be retrieved unconsciously following waking. Memory formation appeared to be mediated by the same brain structures that also mediate wake vocabulary learning.
