If you believe your electric car is not using the 80 percent of electricity generated by conventional fuels, you may also believe the high cost is worth it to save the environment. But there is no running from the environmental problems created by the cars themselves. 

There can be no sustainable value chain when we haven't had new batteries in 30 years. Unfortunately, as long as mandates and subsidies are in effect, there is no incentive to create better technology, which means the only hope is to reuse old, inefficient batteries in order to mitigate the high social and environmental toll electric cars extract now.

To adult audiences in 1977, "Star Wars" was the most realistic special effects they had ever witnessed while to younger people of today, the defects are obvious.

Imidazole dipeptides have been been linked to beneficial effects such as relieving fatigue and, with far less credibility, preventing dementia, and a new study has found that 2-oxo-imidazole-containing dipeptides (2-oxo-IDPs), which have one more oxygen atom than normal imidazole dipeptides, are the most common variety of imidazole dipeptides derivatives in the body.

With ChatGPT a huge fad, students may be excited that their next paper will be easy, because if it is truly AI it will start from the unique seed you give it. Yet it does not work that way. Language models that generate text in response to user prompts use a lot of the same training materials, which means they can plagiarize content in multiple ways.

COVID-19 has done little to boost vaccination rates against other viruses, according to a new analysis.

In a recent survey, just over 50 percent said they had received a flu vaccine, unchanged in a representative national panel from the comparable period last year and within the usual range of years prior to the pandemic. Before people thought COVID-19 was just a bad cold (coronavirus is in the same family and was only declared distinct in the 1960s) they thought the flu was a bad cold. Or believed they were more likely to get the flu if they had a vaccine.

We have a body clock that changes with exposure to sun and a new study finds that while humans don't hibernate, we do sleep longer in the winter.
