UV-Stimulated Fluorescence Reveals Nearly 50 Hidden Pterodactylus Specimens
These relatives of Pterodactylus will allow paleontologists to reconstruct this flying reptile’s life history from hatchling to adulthood. Holotype specimen of Pterodactylus antiquus.

Some People Can’t Imagine Sounds: Anauralia
Some people can’t imagine a dog barking or a police siren; songs can’t get stuck in their heads; they have no inner voices. Anauralia was proposed in 2021 University of Auckland scientists to describe the little-known condition of a silent mind. Now, the University of Auckland will host a global conference on sounds imagined in
Physicists Find Evidence for Matter-Antimatter Asymmetry in Decays of Baryons and Beauty Hadrons
The Standard Model of particle physics predicts an asymmetry between matter and antimatter known as charge-parity (CP) violation. But the size of this asymmetry in the Standard Model is not large enough to account for the imbalance and the asymmetry has so far been observed only in certain decays of particles called mesons. In two
Genetic Testing Is a Gift. But It Shouldn’t be a Present
A few years ago, a patient of mine—let's call her Pandora—purchased four DNA testing kits as holiday gifts for herself and her siblings. She had seen the TV ads promising that a few ounces of spit would uncover otherwise unattainable details about her family’s origins, and she thought it would be fun to share this
