Known to Wiimpatja Aboriginal Owners as kungaka—"the hidden one"—we have now scientifically described it as a new species: Liopholis mutawintji. For decades, this little lizard was thought to be an isolated population of a widespread skink.

Dark matter can accumulate inside a compact star and form a tiny endoparasitic black hole (EBH) at its core. In a highly magnetized star, the growing EBH compresses and twists the magnetic field, which pushes back against infalling matter and slows its growth. This can prevent the star from being destroyed—a process known as magnetically arrested transmutation. Credit: H. A. Adarsha The center of our galaxy is an extreme place.

They were first described more than 150 years ago, based on fossils from South Africa. Since then, many more fossils have been discovered.

But for people in Nigeria, this message is immediate and clear: the flooding is severe and worsening. Moments like this happen all the time on digital platforms. People don't write in perfect, standard English sentences.

Data compiled by the Convention on International Trade in Endangered Species (CITES), the global agreement that regulates trade in threatened animals and plants, indicate that in the 1990s and early 2000s Africa was a leading supplier of live birds to global markets.

Currently, we emit roughly 42 billion metric tons of carbon dioxide from fossil fuel use and land use changes every year. To achieve the targets of the Paris Agreement, which included a long-term commitment to limit global warming to 1.5°C, it will also be necessary to do more than cut emissions.

The tuft of leaves on this goldenrod plant is caused by tiny fly that uses the plant as a nursery. Credit: Steven Bodzin Climate change may reduce yields of crops like corn and soybeans, but it can also give some plants an edge. That's one of the takeaways of a recent study of tall goldenrod, a common wildflower that runs rampant in fields across its native range in North America and other parts of the world where it has been introduced.

The doctoral thesis of Sophia Hollick, Ph.D. '25, a recent graduate of Yale's Wright Lab in professor Reina Maruyama's group, has significantly contributed to answering a decades-long question in her field about whether or not a signal observed in an experiment that has taken data since 1997 was indicative of a direct detection of dark matter.
