Can you overdose on weed?

Back in May of 2019, a coroner in Louisiana claimed to have recorded the first death exclusively caused by weed.

Toxicology results for a woman who died suggested she was killed by an excess amount of THC, the primary psychoactive component of weed, the coroner, Christy Montegut, told the New Orleans Advocate. Montegut failed to find anything else—drugs, alcohol, disease—that could have attributed to her death.

How Do Animals Perceive Time?

I’m writing this on a Tuesday, at 2:26 p.m. Minutes ago, it was 9 a.m., or so it feels; back then, I was enjoying the delusion, refreshed each morning, that I’d accomplish what I needed to do today. I still might—there are hours left in the workday—but I’m wiser than I was when I woke up five hours ago: it’ll be 7pm soon, the day definitively in tatters. Another of Time’s routine beatdowns.

One advantage of being a cat, or a stingray, is not having to think about time this way (and, by extension, death). But are they entirely free from the temporal plane? Do they perceive it in any way? Do some species perceive it more acutely than others? For this week’s Giz Asks, we reached out to a number of experts to find out.

Oldest DNA Sequenced Yet Comes From Million-Year-Old Mammoths

Woolly mammoths were icons of the Ice Age. Starting 700,000 years ago to just 4,000 years ago, they trundled across the chilly steppe of Eurasia and North America. As ancient glaciers expanded across the Northern Hemisphere, these beasts survived the rapidly cooling temperatures with cold-resistant traits, a characteristic they came by not through evolution, as earlier thought. Woolly mammoths, a new Nature study finds, inherited the traits that made them so successful from a mammoth species closer to a million years old.

Apple, Spotify, More Streaming Services Pay $424 Million in Unmatched Royalties for Songwriters and Publishers

On Wednesday, the Mechanical Licensing Collective announced it had received $424.38 million in unmatched royalties from Apple Music, Amazon Music, and Spotify among other streaming services. Variety reports that these streaming services paid the accrued historical unmatched royalties, often called “black box money,” to the MLC in order to get these royalties to copyright holders, songwriters, and publishers who have applied to be MLC members.
