We summarize the week's scientific breakthroughs every Thursday.
- 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.
- Life
Year in review: ‘Minimal genome’ makes its debut
A synthetic cell reported this year jettisons unnecessary genes and embraces human design principles.
- Neuroscience
Year in review: Alzheimer’s drug may clarify disease’s origins
Researchers will now test whether a treatment that swept away amyloid brain plaques also improves cognitive performance.
- Oceans
Readers contemplate corals and more
Coral engineering, ancient almanacs and more in reader feedback.
- Health & Medicine
The fight against infectious diseases is still an uphill battle
The fight against infectious diseases is far from over. The last several decades have seen many outbreaks and global pandemic scares.
- Ecosystems
Oyster deaths linked to ‘atmospheric rivers’
Atmospheric rivers bring strong storms that could have been behind a 2011 California oyster die-off.
- Earth
Fossil microbes show how some life bounced back after dino-killing impact
Pioneering microbes colonized the waters above the Chicxulub crater within hundreds of years following the impact, new research shows.
