We summarize the week's scientific breakthroughs every Thursday.
- Animals
Parasitic worm populations are skyrocketing in some fish species used in sushi
Fishes worldwide harbor 283 times the number of Anisakis worms as fishes in the 1970s. Whether that’s a sign of environmental decline or recovery is unclear.
- Health & Medicine
There’s no evidence the coronavirus jumped from pangolins to people
Pangolins captured in anti-smuggling activities in southern China were found to harbor viruses related to the new coronavirus.
- Paleontology
Fossils of a new dromaeosaur date to the end of the Age of Dinosaurs
Fossils from a new dromaeosaur recovered from New Mexico suggest these fierce predators were diversifying up to the end of the Age of Dinosaurs.
- Genetics
No, the coronavirus wasn’t made in a lab. A genetic analysis shows it’s from nature
Scientists took conspiracy theories seriously and analyzed the coronavirus to reveal its natural origins.
- Genetics
Squid edit their genetic material in a uniquely weird place
Some squids’ seeming ability to edit RNA on the fly could help scientists develop a technique much like the DNA-editing tool CRISPR, but for RNA.
- Life
A new book captures how genetics fills in the story of life’s evolution
In Some Assembly Required, paleontologist Neil Shubin explores how genetic analyses complement paleontological research.
- Paleontology
‘Wonderchicken’ is the earliest known modern bird at nearly 67 million years old
A new fossil find, dubbed the Wonderchicken, is a common ancestor of modern ducks and chickens.
- Climate
How Hurricane Maria’s heavy rains devastated Puerto Rico’s forests
Hurricane Maria wreaked havoc on Puerto Rican forests in some unexpected ways.
- Physics
How slime mold helped scientists map out the cosmic web
Tapping a similarity between a slime mold’s lacy web and the vast threads of matter that connect galaxies, astronomers visualized the cosmic web.
- Artificial Intelligence
An AI that mimics how mammals smell recognizes scents better than other AI
An artificial intelligence modeled after the neural circuitry in mammalian brains can keep learning new aromas without forgetting others.
- Genetics
‘Human Nature’ offers CRISPR novices a basic introduction
A film that introduces people to CRISPR aims to spark debate about how to use the gene editor.
- Paleontology
This ancient dinosaur was no bigger than a hummingbird
The skull of one of these Mesozoic Era birds — the tiniest yet known — was discovered encased in a chunk of amber originally found in Myanmar.
