We summarize the week's scientific breakthroughs every Thursday.
- Animals
For some salamanders, finding a mate is a marathon
Small-mouthed salamanders will travel close to nine kilometers on average to mate, a new study finds.
- Earth
‘Waterworld’ Earth preceded late rise of continents, scientist proposes
Cooling mantle temperatures may have lifted Earth’s continents above sea level, helping spur the Cambrian explosion.
- Neuroscience
Pregnancy linked to long-term changes in mom’s brain
Pregnancy can sculpt a mother’s brain in a way that may help her tune in to her baby.
- Tech
Cells snack on nanowires
Human cells eat silicon nanowires in a process called phagocytosis. Nanowire-infused cells could be a step towards biological electronic devices.
- Animals
Chimps look at behinds the way we look at faces
Humans demonstrate something called the inversion effect when gazing at faces. Chimpanzees do this too — when looking at other chimps’ butts.
- Genetics
50 years ago, alcohol use was linked to several gene variants
50 years later, scientists are still searching for genes that influence drinking.
- Genetics
Proteins that reprogram cells can turn back mice’s aging clock
Proteins that reprogram adult cells to an embryonic-like state can rejuvenate prematurely aging mice.
- Animals
Genome clues help explain the strange life of seahorses
Researchers have decoded the genetic instruction manual of a seahorse (Hippocampus comes) and found clues to its nearly 104-million-year evolutionary history.
- Climate
Arctic kelp forests may create summer refuges from ocean acidification
Long summer daylight revs up carbon capture in Arctic kelp forests, offering a little relief from acidifying ocean water.
- Genetics
Year in review: ‘Three-parent baby’ technique raises hope and concern
Safety and ethical concerns surround controversial mitochondrial replacement therapy.
- Climate
Year in review: Sea ice loss will shake up ecosystems
Researchers are studying the complex biological consequences of polar melting and opening Arctic passageways.
- Genetics
Year in review: How humans populated the globe
DNA studies put new twists on timing of ancient human migrations – but genetics alone are not enough to tell the full story.
