Why is Staphylococcus aureus golden-colored?

Staph aureus excels at evading the human immune system, and its innocuous-seeming color is just one more of its tricks. The characteristic golden color was noted when it was first isolated from infected surgical wounds in 1881[1] From Microbiology in Pictures The pigment is a carotenoid, a cousin to the anti-oxidant vitamin A found in carrots Read More …

What are the pros and cons of diagnostics vs therapeutics?

The short answer is that diagnostics are low-risk low-reward and therapeutics are high-risk high-reward. These risk terms are relative – in either field, most startups fail. The cost of bringing a diagnostic device to market is $25–50M. Novel or highly instrumented technologies are on the high side of that range. The cost of bringing a Read More …

The Game Changers

It’s not often you see a movie that is both information-dense and highly entertaining. “The Game Changers“, which I saw last night at the Boulder International Film Festival, scores highly on both counts. I hadn’t heard of the movie. Its opening montage – which features Ultimate Fighting, powerlifters, biochemical diagrams and rhinoceroses – provides few Read More …

When starting a biotech, does the founder have to be an expert in the thing that the company focuses on?

Well, yes. But the thing that a startup must focus on is not science. It’s raising money so that you can do science.

How do you prevent development of antibiotic resistance when suffering from tuberculosis?

Slow growth tends to make bacteria intrinsically less susceptible to antibiotics, and being inside a host cell makes it more difficult to achieve a high, therapeutically-effective dose of an antibiotic. To add to the challenge, resistance to some of the most effective anti-TB antibiotics (like rifampin) Read More …

How do you find an investor for a biotech company that reverses damages of aging at a cellular level (requires 100 million)?

The first thing you need is a story. The story has many chapters – about technology, about your team, about clinical utility, about intellectual property, about risks – but it has to have a certain ending. That ending is one in which investors make a 10X return on their investment. At least. Few early-stage investors Read More …

Is it true that drug price regulation would be as bad as Mao’s Great Leap Forward?

Published on Apple News “True” is far too strong a word. But the estimate is neither ridiculous nor a troll, despite the use of such an inflammatory comparator. The argument is simple – a cited RAND study estimates the disincentivization to pharma R&D of drug price regulation would cost the average North American or European of ages 55–65 about Read More …

How does CancerSEEK compare to other liquid biopsies?

This work[1] blows away previous efforts. The word “breakthrough” is used far too often to describe results that are incremental, or that are promising but not well-supported. CancerSEEK is a genuine breakthrough. The gold standard for cancer diagnosis is the biopsy – a bit of suspect tissue is excised and studied, and determined to be benign Read More …
