To be sure, newer lithium-ion batteries are developing rapidly, lasting far longer between charges. The amount of energy they put out relative to their volume—their “energy density”—has improved by a striking 9 percent annually between 2015 and 2023, says Simon Mui, an expert in battery technology who works for the Natural Resources Defense Council based…
On Wednesday, New York Governor Kathy Hochul shocked the state and the country when she announced she would indefinitely shelve New York City’s long-in-development congestion pricing scheme.

Gill did not face charges then, but this time could be different. The securities regulator for the state of Massachusetts has confirmed it is looking into Gill’s recent conduct, without providing specifics.

To ensure the best sun protection, it’s important to know exactly what you’re getting when you pick up a bottle of sunscreen. “Much of what you see on the label is marketing, which can make it difficult to decode what’s truly meaningful,” says Joshua Zeichner, MD, director of cosmetic and clinical research in dermatology at…
To find out, our experts blind-tasted seven store-brand vanilla ice creams as well as two famous brand-name ones: Breyers and Häagen-Dazs. Some of the ice creams we tested are billed as “premium,” like the Häagen-Dazs, Aldi, and Trader Joe’s products shown below. This means they usually contain less air and have a richer, denser texture…
ChatGPT developer OpenAI’s approach to building artificial intelligence came under fire this week from former employees who accuse the company of taking unnecessary risks with technology that could become harmful. Today OpenAI released a new research paper apparently aimed at showing it is serious about tackling AI risk by making its models more explainable. In…
SpaceX has completed a mostly successful fourth test of its revolutionary new Starship rocket, a key step toward returning humans to the Moon and, maybe one day, landing on Mars. The flight, integrated flight test 4 (IFT-4), lifted off today from SpaceX’s Boca Chica test site in Texas at 7:50 am Central time. Standing 233…
The Crown moniker dates back almost 70 years, making it the automaker’s longest-running model name. While absent from the U.S. market for about half a century, it has been applied to a series of regal sedans overseas for decades. Now the automaker is redefining “Crown” by applying it to a growing line of models that…
In CR’s sunscreen tests, we use the Food and Drug Administration’s sunscreen testing protocol as a model. But as with all products, we do our own scientific, laboratory-based testing to identify differences in performance and give consumers a comparative evaluation. We buy sunscreens at retailers, the way consumers do, and test three samples of each…
