“On March 13, the Institute celebrated the publication of The Usefulness of Useless Knowledge (Princeton University Press), which features IAS Founding Director Abraham Flexner’s classic essay of the same title, first published in Harper’s magazine in 1939.”
DNA protects itself from damage naturally, and scientists are hoping to gain insight into how the process works. When DNA is bathed in ultraviolet light, it can eject a single proton from a hydrogen atom to rid itself of excess energy, ensuring other chemical bonds remain intact. This protective mechanism is called an excited state proton transfer, and it is the focus of new research by a team of scientists.
The researchers used the Linac Coherent Light Source (LCLS) at the SLAC National Accelerator Laboratory to generate X-ray laser pulses capable of probing the nitrogen molecule — in the simple molecule 2-thiopyridone — for quadrillionths of a second. The short period of time matters because when molecules are exposed to this kind of light they react incredibly quickly. The brightness of the light is equally important, because only very brilliant illumination renders these ultrafast changes visible to the researchers.
“The effective altruism movement could be more effective if it encouraged adoption of its principles within causes and geographies, not just across them.”
NASA has announced the recipients of its most recent round of highly experimental projects it deems promising enough to fund. These NASA Innovative Advanced Concepts aren’t guaranteed to go all the way, but are rather sort of low-risk, high potential reward moonshots — science fiction they hope will be more the former than the latter.
The awards are a regular occurrence and divided into Phase I and Phase II: Phase I projects are more or less in the concept stage and will get around $125,000 over 9 months to see if they’re at all viable, essentially from “might work” to “should work.” Phase II projects get a more flexible amount, but as much as half a million dollars over 2 years, to see about going from “should work” to “works.”
The full list of awards can be found here, but I’ve selected a few I think are especially promising.
Science-fiction author William Gibson famously said, “The future is already here; it’s just not evenly distributed yet.”
Nowhere is that more true than in the tech world, where it’s easy to think that innovations, products and services available to us are ubiquitous, even when their distribution is, in fact, very limited.
Many of the innovations that we take for granted are simply not available elsewhere.
Scientists are proposing new methods of stabilizing the design of the first of its kind tiny and lightweight space probe.

Ever since Alpha Centauri was discovered, scientists have been trying to devise new ways of studying it. The Alpha Centauri star is around 4.37 light-years away from Earth, and it is expected that it will take a minimum of 20 years to reach near it.
Every minute in the United States, 30 people require a blood transfusion. That equates to a lot of blood, and the problem is that not enough people donate. This bottleneck has long been an issue for medicine, and so many have been trying to find a way to artificially create large volumes to meet this demand.
A team of researchers from the University of Bristol and NHS Blood and Transplant may have finally cracked it. They’ve made a major breakthrough in the process of mass producing red blood cells, in what could technically be an unlimited supply of the stuff. While they now have a biological way of achieving this, they now need the manufacturing technology on a large enough scale in order to mass produce it.
Scientists have been able to create artificial blood before, but these earlier methods have been incredibly inefficient. They worked by taking stem cells, and then directly inducing them to form red blood cells. By doing this, they could create maybe 50,000 cells in one go, far short of the trillions typically needed for a blood transfusion.
