A new biosensor can detect bird flu in five minutes
Over the winter, eggs suddenly became all but impossible to buy. As a bird flu outbreak rippled through dairy and poultry farms, grocery stores struggled to keep them on shelves.
The shortages and record-high prices in February raised costs dramatically for restaurants and bakeries and led some shoppers to skip the breakfast staple entirely. But a team based at Washington University in St. Louis has developed a device that could help slow future outbreaks by detecting bird flu in air samples in just five minutes. Read the full story.

This Texas chemical plant could get its own nuclear reactors
Nuclear reactors could someday power a chemical plant in Texas, making it the first with such a facility onsite. The factory, which makes plastics and other materials, could become a model for power-hungry data centers and other industrial operations going forward.
The plans are the work of Dow Chemical and X-energy, which last week applied for a construction permit with the Nuclear Regulatory Commission, the agency in the US that governs nuclear energy.
While it’ll be years before nuclear reactors will actually turn on, this application marks a major milestone for the project, and for the potential of advanced nuclear technology to power industrial processes. Read the full story.

The big story
Inside effective altruism, where the far future counts a lot more than the present
Since its birth in the late 2000s, effective altruism has aimed to answer the question “How can those with means have the most impact on the world in a quantifiable way?”—and supplied methods for calculating the answer.
It’s no surprise that effective altruisms’ ideas have long faced criticism for reflecting white Western saviorism, alongside an avoidance of structural problems in favor of abstract math. And as believers pour even greater amounts of money into the movement’s increasingly sci-fi ideals, such charges are only intensifying. Read the full story.
