The story of human evolution is not a simple ladder from early forms to more advanced ones. For decades, fossils shaped a picture of steady, linear progress – one form giving rise to another in a neat sequence.

Tea (Camellia sinensis) leaves are used for drinking for their flavor. It is the same plant that is used for making black tea (e.g., Assam, Darjeeling, etc.), oolong green tea (Chinese tea), and Japanese green teas (Hojicha, Sencha, Gyokuru, & Matcha). In black tea, oxidation is used in processing the leaves, which are exposed to air, giving them a dark color and smoky flavor. Oolong green tea uses partial oxidation, in which leaves are withered for only a short period.  In Japanese teas, oxidation is prevented, leaving them rich in antioxidants and thus making them more beneficial from a health perspective.

Ancient, fossilized teeth, uncovered during a decades-long archaeology project in northeastern Ethiopia, indicate that two different kinds of hominins, or human ancestors, lived in the same place between 2.6 million and 2.8 million years ago — and one of them may be a previously unknown species.

Temperatures in the Mojave Desert are scorching hot nowadays, as they are every summer, but summer 2025 doesn’t look as hot for Las Vegas as in previous years in terms of visitor numbers.

The airport connector is a key road to get around Harry Reid International Airport, but some are concerned the lights around the tunnel can impact drivers and passengers alike.

Machine learning and deep learning technologies for enhancing the ability to predict bleeding risks is just one of many dramatic changes occurring in the management of hemophilia. Recent advances in artificial intelligence (AI) applications are opening new avenues for the management of hereditary hemophilia (A and B) and acquired hemophilia. AI holds the promise for optimizing treatment regimens and monitoring disease progression with greater precision, according to a review published in the International Journal of Molecular Sciences.

The Silver State and the Lone Star State may swing different ways politically, but they have at least one thing in common: an “F” rating for partisan gerrymandering. Nevada’s 2021 rejiggering of the state’s congressional districts received the failing grade from Princeton University’s nonpartisan Gerrymandering Project Redistricting Report Card for giving Democrats a significant electoral advantage in the U.S. House of Representatives.

Here in Nevada, no mid-decade redistricting has ever been attempted. But that doesn't mean the state hasn't seen its share of redistricting drama on both sides of the aisle. And while repeated attempts to turn redistricting over to an independent commission here have failed, one proponent of the idea says she'll try again this year.
