Space travel has known effects on human health and biology. Some, such as loss of bone density, are well understood, while others, like inflammation, are not. Now, organ-on-a-chip maker Emulate Inc. is conducting experiments on the International Space Station U.S. National Laboratory (ISS-NL) aimed at revealing clues to how the brain functions in microgravity.

University of California San Diego engineers have developed tiny 2D sensors that pop up to become a 3D assemblage of microscopic sensors for directly measuring the movement and speed of electrical signals inside the heart. According to nanoengineering professor Sheng Xu, the nanotechnology has enormous implications for heart doctors anxious to better diagnose and treat arrhythmia, heart attack and other diseases.

Cancer trials that stratify patients using biomarkers increase their likelihood of proceeding to the next phase more than 500% compared to trials run without biomarkers, Canadian researchers recently determined, and biotech companies have invested heavily in identifying new biomarkers for a wide range of applications. Genialis Inc. has tackled the problem of huge investment in biomarkers with little return by developing a platform that combines artificial intelligence and machine learning.

The epic rise and fall of Elizabeth Holmes, founder of Theranos Inc., will preoccupy the world of business for decades to come, but this story has also left a large footprint in the world of clinical diagnostics. David Stein, CEO of Babson Diagnostics Inc., of Austin, Texas, told BioWorld that investors are a bit more wary than usual because of the Theranos saga, forcing test developers to be more rigorous in test development and more transparent with investors about a test.

Investors including SOSV, Cultivate(MD), Wavemaker360 Health, Blu Venture Investors and Broad Street Angels are backing Strados Labs LLC with $4.5 million. The pre-series A funding will be used to accelerate development of the company’s smart sensor platform Resp. The funding comes after Strados received FDA clearance for the product in December 2021 and brings its total raised to $7 million.

Over the course of the past two years, two presidential administrations and the U.S. Congress have set considerable sums of money aside for testing for the COVID-19 pandemic, but reports of shortages of tests have prompted a response from Capitol Hill.

PARIS – Milvue SAS completed a series A round, raising more than $9 million towards deployment of its artificial intelligence-based software solution used for diagnosis and full triage of osteoarticular pathologies in emergency departments.

In the season of college bowl games, two long-time rivals are vying for another title, the right to claim being the first to install Siemens Healthineers AG’s Magnetom Free.Max magnetic resonance imaging (MRI) system. Both the Ohio State University and the University of Michigan said they were first in the U.S. to put in the recently approved system.

The run on at-home COVID-19 tests may be for naught. The FDA warned that the popular rapid antigen tests recommended to keep New Year’s Eve revelers, relatives visiting elderly grandparents and workers exposed to the coronavirus from spreading COVID-19 are less likely to detect the Omicron variant than earlier strains of the virus. “Early data suggest that antigen tests do detect the Omicron variant but may have reduced sensitivity,” the agency said in an update on Dec. 29. Despite the higher rate of false negatives, the FDA said individuals should continue to use the tests. Those experiencing symptoms or with a high likelihood of infection based on exposure should follow-up with a molecular test if their antigen test returns a negative result.

The Verifying Accurate Leading-edge IVCT Development (VALID) Act seems poised for passage in 2022, a bit of welcome relief for those stuck in the regulatory twilight world of the lab-developed test (LDT). However, Carly McWilliams, director of regulatory policy for North America for Roche Inc., said recently at the recent Food and Drug Law Institute enforcement meeting that the VALID Act is likely to leave the question of a user fee schedule for a future Congress, given that the associated rulemaking, guidance development and compliance activities are likely to consume the better part of, if not the entirety of, the next five years.
