Here’s how magnetic fields shape desert ants’ brains
Exposure to a tweaked magnetic field scrambled desert ants’ efforts to learn where home is — and affected neuron connections in a key part of the brain.

Big monarch caterpillars don’t avoid toxic milkweed goo. They binge on it
Instead of nipping milkweed to drain the plants’ defensive sap, older monarch caterpillars may seek the toxic sap. Lab larvae guzzled it from a pipette.

Messed-up metabolism during development may lead guts to coil the wrong way
Tadpoles exposed to a metabolism-disrupting herbicide had malformed intestines, providing clues to a human condition called intestinal malrotation.

A new DNA leaf swab technique could revolutionize how we monitor biodiversity
Simple swabs of just 24 leaves in Uganda’s Kibale National Park provided a genetic snapshot of 52 animals in the tropical forest.

The development of quantum dots wins the 2023 Nobel prize in chemistry
Moungi Bawendi, Louis Brus and Alexei Ekimov split the prize for their work in creating nanoparticles whose properties depend on their size.

Social media harms teens’ mental health, mounting evidence shows. What now?
Recent studies suggest a causal link between teen social media use and reduced well-being. Now, some researchers are looking into possible mechanisms.

Bacteria that can make humans sick could survive on Mars
Experiments suggest that common illness-causing microbes could not only survive on the Red Planet but also might be able to thrive.

These bats are the only mammals known to mate more like birds
Male serotine bats have penises too large for penetration. To mate, the animals rub their genitals against each other, somewhat like birds’ cloacal kiss.

Gene editing can make chickens resistant to bird flu
Chickens genetically modified to be impervious to avian influenza may one day prevent the spread of the disease on farms, a study suggests.

Invasive yellow crazy ants create male ‘chimeras’ to reproduce
Yellow crazy ants are first known species where chimerism is required in males: Each of their cells holds DNA from just one of two genetic lineages.
- Paleontology
A rare 3-D tree fossil may be the earliest glimpse at a forest understory
The 350-million-year-old tree, which was wider than it was tall thanks to a mop-top crown of 3-meter-long leaves, would look at home in a Dr. Seuss book.

Deblina Sarkar is building microscopic machines to enter our brains
The ultratiny devices can communicate wirelessly from inside living cells and may one day help cure brain diseases.
