We summarize the week's scientific breakthroughs every Thursday.
- Life
Donor mitochondria could influence metabolism, aging
Mitochondrial DNA donation could have unexpected long-term health consequences for “three-parent babies.”
- Animals
To zip through water, swordfish reduce drag
A newly discovered oil-producing organ inside the swordfish’s head gives the animal slick skin to swim faster.

Lionfish invasion comes to the Mediterranean
Scientists had thought that the Mediterranean was too cold for lionfish to permanently settle there. But now they’ve found a population of the fish off Cyprus.
- Neuroscience
Rewarding stimulation boosts immune system
Activating feel-good nerve cells boosts mice’s immunity, a new study suggests.
- Life
Letting parasites fight could help battle drug resistance, too
Helping one strain of malaria trounce another in lab mice demonstrates a way of avoiding the evolution of drug resistance.
- Climate
Warming alters mountain plant’s sex ratios
Global warming has different effects on male and female plants. Tracking sex ratio shifts could be a fast signal of climate change, researchers say.
- Animals
Frigate birds fly nonstop for months
The great frigate bird can fly for up to two months without landing, thanks to a boost from wind and clouds.
- Animals
Sneaky male fiddler crabs entrap their mates
Some male banana fiddler crabs get a female to mate with them by trapping her in their burrow, a new study finds.
- Science & Society
Empathy for animals is all about us
We extend our feelings to what we think animals are feeling. Often, we’re wrong. But anthropomorphizing isn’t about them. It’s about us.
- Health & Medicine
This week in Zika: vaccine progress, infection insights
Vaccine candidates for Zika virus take a step forward, birth defects span spectrum of problems and doubts about Zika’s link to microcephaly may be extinguished by new reports from Colombia.
- Health & Medicine
Vaccines could counter addictive opioids
Scientists turn to vaccines to curb the growing opioid epidemic.
- Paleontology
Parasites wormed way into dino’s gut
Tiny slimed tunnels in the guts of a 77-million-year-old duck-billed dinosaur fossil offer the first hard evidence that dinosaurs may have been infected by parasitic worms, paleontologists say.
