Meg Duff: For Science, Quickly, I’m Meg Duff. [CLIP: Show music] Meg Duff: Last week, if you missed it, I was up in Harvard Forest, learning about a hidden economy: underneath our feet, plants and fungi are constantly trading carbon and nutrients. Duff: Trees use carbon as currency to trade with fungi. Scientists have figured… Continue reading The Fungi Economy, Part 3: Can Climate Modeling from Space Save Our Forests?
These Technologies Could Defeat China’s Missile Barrage and Defend Taiwan
Earlier this year, a group of experts from RAND and the Special Competitive Studies Project launched a new wargame effort around China’s invasion of Taiwan—but unlike most D.C.-based wargames, this effort heavily involved members of the commercial technology sector, in order to understand what near-term capabilities might be brought to bear on a Taiwan scenario.… Continue reading These Technologies Could Defeat China’s Missile Barrage and Defend Taiwan
The Biggest Smallest Triangle Just Got Smaller
Consider a square with a bunch of points inside. Take three of those points, and you can make a triangle. Four points define four different triangles. Ten points define 120 triangles. The numbers grow quickly from there — 100 points define 161,700 different triangles. Each of those triangles, of course, has a particular area. Hans… Continue reading The Biggest Smallest Triangle Just Got Smaller
The War in Ukraine, Income Share Agreements, the Tech ‘Cold War’: RAND Weekly Recap
This week, we discuss why comparing the war in Ukraine to World War I is misleading; income share agreements as an alternative to student loans; how India is edging out China in South Asia; how to plan ethical influence operations; parental involvement in schools; and the U.S.-China race for technological supremacy. Photo by Stringer/Reuters Many… Continue reading The War in Ukraine, Income Share Agreements, the Tech ‘Cold War’: RAND Weekly Recap
Physicists Observe ‘Unobservable’ Quantum Phase Transition
In 2019, Noel and her colleagues began collaborating with two theorists who had come up with an easier way of doing the experiment. They had worked out a way of setting aside one qubit that, like a canary in a coal mine, could serve as a bellwether for the state of the entire chain. The… Continue reading Physicists Observe ‘Unobservable’ Quantum Phase Transition
ECOWAS: In Need of Help in Niger?
News reports indicate that Nigerian President Bola Tinubu sought the national legislature’s backing for a possible military intervention by the Economic Community of West African States (ECOWAS) to turn back a coup that toppled the government of Nigerien President Mohamed Bazoum. An ECOWAS intervention would have a better chance of succeeding if other nations joined… Continue reading ECOWAS: In Need of Help in Niger?
The Usefulness of a Memory Guides Where the Brain Saves It
Scientists have recognized that memory formation is a multistage process since at least the early 1950s, in part from their studies of a patient named Henry Molaison — known for decades in the scientific literature only as H.M. Because he suffered from uncontrollable seizures that originated in his hippocampus, surgeons treated him by removing most… Continue reading The Usefulness of a Memory Guides Where the Brain Saves It
Five Charts That Tell Us About the State of Public Education Right Now
A lot happens every year in U.S. public schools, and it can be hard to keep track of it all. To monitor trends in public education, the RAND Corporation fields over a dozen surveys annually to teachers, principals, and superintendents who are members of the American Educator Panels. These five charts taught us the most… Continue reading Five Charts That Tell Us About the State of Public Education Right Now
Why Mathematical Proof Is a Social Compact
Now, with the use of not just computers but even AI, how is the notion of proof changing? We’ve moved to a different place, where computers can do some wild things. Now people say, oh, we’ve got this computer, it can do things people can’t. But can it? Can it actually do things people can’t?… Continue reading Why Mathematical Proof Is a Social Compact
Pandemics Don’t Really End—They Echo
The public health emergency related to the COVID-19 pandemic officially ended on May 11, 2023. It was a purely administrative step. Viruses do not answer to government decrees. Reported numbers were declining, but then started coming up again during the summer. By August, hospital admissions climbed to more than 10,000 a week. This was nowhere… Continue reading Pandemics Don’t Really End—They Echo
