Thin on the left so far

None of the 7 outlets with a published leaning rating that ran this story are rated left.

This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.

The U.S. Food and Drug Administration (FDA) is updating its regulations to remove language that could suggest animal testing is the only acceptable method for generating safety information for regulatory decisions. The agency's new rule replaces terms such as 'animal tests' and 'animal studies' with the broader terms 'nonclinical tests' and 'nonclinical studies'. This change aligns the regulations with the FDA Modernization Act 2.0, which was enacted in 2022.

The FDA's action is part of a broader initiative announced by the Department of Health and Human Services (HHS) to accelerate human-based research and reduce reliance on animal testing across its agencies. HHS stated that its agencies, including the FDA, National Institutes of Health (NIH), Centers for Disease Control and Prevention (CDC), and the Advanced Research Projects Agency for Health (ARPA-H), have launched more than 20 initiatives. These efforts aim to modernize how the federal government conducts, funds, and evaluates biomedical research. HHS indicated that some of these changes are expected to spare hundreds of non-human primates and more than one million horseshoe crabs annually.

The National Institutes of Health (NIH) announced more than $88 million in biomedical infrastructure investments to support human-based research. The NIH also plans to establish a new laboratory at the NIH Clinical Center that will combine human organoids, robotics, artificial intelligence, and advanced data capabilities. Additionally, the NIH is seeking to add scientists with human-based research expertise to its grant-review process and is assessing the feasibility of annually reporting the number of live vertebrate animals used at NIH-funded institutions.

Disagreement on timing of initiatives

The Epoch Times digest states that HHS has launched more than 20 initiatives toward these goals during President Donald Trump's administration. In contrast, Florida's Voice digest states the department said the moves expand more than 20 initiatives launched since Health and Human Services Secretary Robert F. Kennedy Jr. took office.

What the coverage left out

No left- or centre-rated outlet reported on this story. The unrated reports from Animal Wellness Action and The Center for a Humane Economy mention that the FDA's rule and the bipartisan FDA Modernization Act 3.0 are not identical, with the latter containing a statutory technical correction that the FDA cannot make through regulation. This detail was not mentioned in any of the right-rated reports.

Questions about this coverage

How did the left and right cover FDA updates rules to reduce animal testing in research?
Of the 7 outlets on this story carrying a published leaning rating, 0% are rated left, 0% are rated centre, 100% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 9. The sections above set out what each side emphasised, in its own terms.

Too few of the outlets on this story carry a published leaning rating to say. 7 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
Is the coverage of FDA updates rules to reduce animal testing in research biased?
FDA updates rules to reduce animal testing in research is one event reported by 9 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
Which side is not reporting FDA updates rules to reduce animal testing in research?

What is the broader goal of these changes?
The changes are part of a department-wide effort by HHS to accelerate human-based research and reduce reliance on animal testing. This aims to modernize how the federal government conducts, funds, and evaluates biomedical research, putting human biology at the center of science.
How many animals might be spared annually?
HHS stated that these changes are expected to spare hundreds of non-human primates and more than one million horseshoe crabs annually. This is a projected impact of the new regulations and broader initiatives.
