Harvard Has Almost Half a Billion Dollars in Crypto

1 month 1 week ago
An anonymous reader shares a report: Harvard is ramping up its holdings in cryptocurrency. The nation's oldest university reported a $443 million investment in BlackRock's iShares Bitcoin Trust in the third quarter. The school now holds 6.8 million shares of the exchange-traded fund, up from 1.9 million in the second quarter. The digital currency amounts to a little less than 1% of the school's $57 billion endowment. Other schools are bullish on crypto as well. Brown University reported holding $13 million of the BlackRock bitcoin ETF in the second quarter and Emory University reported holding $20 million of Grayscale's Bitcoin Mini Trust ETF as of March.

Is Video Watching Bad for Kids? The Effect of Video Watching on Children's Skills

1 month 1 week ago
Abstract of a paper on NBER: This paper documents video consumption among school-aged children in the U.S. and explores its impact on human capital development. Video watching is common across all segments of society, yet surprisingly little is known about its developmental consequences. With a bunching identification strategy, we find that an additional hour of daily video consumption has a negative impact on children's noncognitive skills, with harmful effects on both internalizing behaviors (e.g., depression) and externalizing behaviors (e.g., social difficulties). We find a positive effect on math skills, though the effect on an aggregate measure of cognitive skills is smaller and not statistically significant. These findings are robust and largely stable across most demographics and different ways of measuring skills and video watching. We find evidence that for Hispanic children, video watching has positive effects on both cognitive and noncognitive skills -- potentially reflecting its role in supporting cultural assimilation. Interestingly, the marginal effects of video watching remain relatively stable regardless of how much time children spend on the activity, with similar incremental impacts observed among those who watch very little and those who watch for many hours.

Iran Begins Cloud Seeding To Induce Rain Amid Historic Drought

1 month 1 week ago
Authorities in Iran have sprayed clouds with chemicals to induce rain, in an attempt to combat the country's worst drought in decades. From a report: Known as cloud-seeding, the process was conducted over the Urmia lake basin on Saturday, Iran's official news agency Irna reported. Urmia is Iran's largest lake, but has largely dried out leaving a vast salt bed. Further operations will be carried out in east and west Azerbaijan, the agency said. Rainfall is at record lows and reservoirs are nearly empty. Last week President Masoud Pezeshkian warned that if there is not enough rainfall soon, Tehran's water supply could be rationed and people may be evacuated from the capital. Cloud seeding involves injecting chemical salts including silver or potassium iodide into clouds via aircraft or through generators on the ground. Water vapour can then condense more easily and turn into rain. The technique has been around for decades, and the UAE has used it in recent years to help address water shortages. Iran's meteorological organisation said rainfall had decreased by about 89% this year compared with the long-term average, Irna reported.
