Some fish have legs that can taste prey underfoot
Taste buds on those legs may explain why northern sea robins are so good at finding food that is buried in the sandy seafloor.

Can this ‘woolly mouse’ help bring back extinct mammoths?
Scientists created mice with woolly mammoth–like traits. But that doesn’t mean we’re close to bringing back woolly mammoths.
- Animals
Dire wolves or not, these pups could help counter extinction
Some question if these are just gene-tweaked gray wolves. Still, the tech behind the new "dire wolves" might help some living at-risk species avoid extinction.
- Genetics
This young biologist looked for links between diet and dyslexia
Thermo Fisher JIC finalist Giselle Drewett wanted to know how lifestyle might influence a gene related to dyslexia.
- Plants
Microbes give plants a way to make ‘meaty’ nutrients
Enzymes from animals helped a test plant make two nutrients essential for a balanced diet. Normally, those nutrients would only be found in meat.

Scientists Say: Chimera
What does it mean to be an individual? The genetic mashups called chimeras might challenge your assumptions.
- Microbes
Under the microscope, this biologist sees a tiny jungle
Sally Warring has long been captivated by the beauty of mostly single-celled life forms called protists.
- Genetics
The discovery of microRNA wins the 2024 Nobel Prize in physiology
Victor Ambros and Gary Ruvkun discovered tiny snippets of genetic material, called microRNAs, that play a big role in making sure cells work as they should.

The last woolly mammoths offer new clues to why this species died out
The last woolly mammoth herd experienced a drop in genetic variation. But this is likely not what doomed these majestic beasts to extinction, new data suggest.
- Genetics
Scientists Say: Telomere
These protective caps at the ends of chromosomes play a key role in cell replication.
- Animals
Freeze-drying turned a woolly mammoth’s DNA into ‘chromoglass’
The 3-D structure of this now-glassy DNA revealed similarities — and differences — between woolly mammoths and elephants.
- Plants
Gene editing may help rice better withstand climate change
Three genes may limit the ability of rice to handle dry or salty conditions. A Regeneron ISEF finalist shows that CRISPR could target and change them.
