Under President Trump, the Food and Drug Administration may no longer approve seasonal COVID-19 vaccines updated for the virus variants circulating that year, according to recent statements by Trump administration officials.

Since the acute phase of the pandemic, vaccine manufacturers have been subtly updating COVID-19 shots annually to precisely target the molecular signatures of the newest virus variants, which continually evolve to evade our immune responses. So far, the FDA has treated these tweaked vaccines the same way it treats seasonal flu shots, which have long been updated annually to match currently circulating strains of flu viruses.

The FDA does not consider seasonal flu shots brand-new vaccines. Rather, they're just slightly altered versions of the approved vaccines. As such, the regulator does not require companies to conduct lengthy, expensive vaccine trials to prove that each slightly changed version is safe and effective. If they did, generating annual vaccines would be virtually impossible. Each year, from late February to early March, the FDA, the Centers for Disease Control and Prevention, and the World Health Organization direct flu shot makers on what tweaks they should make to shots for the upcoming flu season. That gives manufacturers just enough time to develop tweaks and start manufacturing massive supplies of doses in time for the start of the flu season.

Since the Iberian Peninsula lost power in a massive blackout, grid operators are in the process of trying to restore power to millions of customers and businesses. As you might imagine, the process—termed a "black start"—is quite a bit more challenging than flicking on a switch. However, the challenge is made considerably more difficult because nearly everything about the system—from the management hardware that remotely controls the performance of the grid to the power plants themselves—needs power to operate.

Restarting the grid

You might think that a power plant could easily start generating power, but in reality, only a limited number of facilities have everything they need to handle a black start. That's because it takes power to make power. Facilities that boil water have lots of powered pumps and valves, coal plants need to pulverize the fuel and move it to where it's burned, etc. In most cases, black-start-rated plants have a diesel generator present to supply enough power to get the plant operating. These tend to be smaller plants, since they require proportionally smaller diesel generators.

The initial output of these black start facilities is then used to provide power to all the plants that need an external power source to operate. This has to be managed in a way that ensures that only other power plants get the first electrons to start moving on the grid, otherwise the normal demand would immediately overwhelm the limited number of small plants that are operating. Again, this has to be handled by facilities that need power in order to control the flow of energy across the grid. This is why managing the grid will never be as simple as "put the hardware on the Internet and control it remotely," given that the Internet also needs power to operate.

On Thursday, OpenAI announced the addition of shopping features to ChatGPT Search. The new feature allows users to search for products and purchase them through merchant websites after being redirected from the ChatGPT interface. Product placement is not sponsored, and the update affects all users, regardless of whether they've signed in to an account.

Adam Fry, ChatGPT search product lead at OpenAI, showed Ars Technica's sister site Wired how the new shopping system works during a demonstration. Users researching products like espresso machines or office chairs receive recommendations based on their stated preferences, stored memories, and product reviews from around the web.

According to Wired, the shopping experience in ChatGPT resembles Google Shopping. When users click on a product image, the interface displays multiple retailers like Amazon and Walmart on the right side of the screen, with buttons to complete purchases. OpenAI is currently experimenting with categories that include electronics, fashion, home goods, and beauty products.

Backblaze is dismissing allegations from a short seller that it engaged in “sham accounting” that could put the cloud storage and backup solution provider and its customers' backups in jeopardy.

On April 24, Morpheus Research posted a lengthy report accusing the San Mateo, California-based firm of practicing “sham accounting and brazen insider dumping.” The claims largely stem from a pair of lawsuits filed against Backblaze by former employees Huey Hall [PDF] and James Kisner [PDF] in October. Per LinkedIn profiles, Hall was Backblaze’s head of finance from March 2020 to February 2024, and Kisner was Backblaze’s VP of investor relations and financial planning from May 2021 to November 2023.

As Morpheus wrote, the lawsuits accuse Backblaze’s founders of participating in “an aggressive trading plan to sell 10,000 shares a day, along with other potential sales from early employee holders, against ‘all external capital markets advice.’” The plan allegedly started in April 2022, after the IPO lockup period expired and despite advisor warnings, including one from a capital markets consultant that such a trading plan likely breached Backblaze’s fiduciary duties.
