Three Horror Movies That Even a Scientist Could Love

As a scientist I have mixed feelings about SF-oriented horror, which tends to show my lab coat-wearing brethren as myopic, obsessive, morally challenged individuals or as humorless skeptics. When Fringe needed a scientist for its team of white hats, the best they could come up with was a former, vaguely repentant mad scientist. Kind of unfair, considering how many plot ideas they've stolen from our journals. But there are a few bio-inspired scary movies out there that I would recommend. More »

Where Are My Medical Nanobots?

Reader Wendy asks: When will nanobots clean out my arteries? While medical molecular machines are not likely to appear in the clinic soon, there's a decent amount of research going into the development of nanoscale robotics, and not only for therapeutic use. One could easily imagine these widgets appearing in diagnostic assays and nano-scale manufacturing. Before we can hope to command tiny robots to crawl or swim to a damaged or stenotic artery to effect repairs, we first need to build tiny robots capable of crawling or swimming. More »

What's the Future of Cancer Diagnosis?

I talked about the importance of early cancer diagnosis in a previous post, and reader Ian wrote back to ask for more detail. Early detection can be life-saving, but accuracy in these tests is also a serious problem - a test that misses existing cancers is obviously bad, but one that detects cancers that aren't there or suggests a future cancer that will never develop can expose patients to unnecessary procedures, some of them invasive. I'm not knocking cancer screening — just noting that, for a given test, the potential for early detection is not the whole story. Early unambiguous detection is the goal. Let's take a look at a few of the methods we can apply to improve cancer diagnosis. More »

Will I Evolve Into a Being of Pure Energy?

Welcome back to Ask a Biogeek, a column where biology researcher Terry Johnson answers questions about biology — no matter how weird. Back when I discussed our unlikeliest futures as a species, one commenter added to the list of improbabilities our eventual transcendence into a non-corporeal form. That's hardly the only evolutionary myth propagated by science fiction. Misunderstandings of basic evolutionary theory are often so egregious they make "hearing explosions in space" seem mild in comparison. Warning: In discussing a few of the worst and most common offenses against evolutionary common sense, I'm going to spoil the hell out of a lot of old science fiction. More »

Son Of "Where Are My Cybernetic Implants?"

Welcome to Ask a Biogeek, a column where you ask UC Berkeley researcher Terry Johnson any question you want — no matter how weird. There seems to be a strong correlation between my posting an article on a subject, and my RSS feeds filling up with exciting new research, which I then wish I'd been able to include. The usual post-article deluge of goodness, combined with the poster for a Neuromancer movie practically forced me to revisit the burning question: Where are my cybernetic implants? More »

Where Are My Cybernetic Implants?

A reader who would like to remain anonymous asks:

As a disabled person whose body is basically falling apart (details too gross to go into), I've been wondering for a long time when I can get my cyborg transformation underway. What's the status of materials that are compatible with being implanted in the body?

First of all, Anonymous, my best wishes. I hope that the next advance coming 'round the bend is a comfort to you. There are two fundamental approaches to organ-level repair: the biological approach, which includes transplants and tissue engineered organs, or what we'll call the cybernetic approach, which creates replacements out of artificial materials capable of appropriately interacting with the body. Keeping this in mind, let's take a look at the cutting edge of human-machine interfaces. More »

Where Is My Uterine Replicator (AKA Artificial Womb)?

Reader Karen asks:

One of my favourite sci-fi conceits in the Vorkosigan works of Lois McMaster Bujold is the uterine replicator. Sticking a fetus in a regulated jar until it's come full term and I can get my new baby boy, girl or hermaphrodite without all the vomiting, constant peeing, strenuous pushing, pooping on the operating table, and possible endangerment to life, reproductive organs and blood sugar levels sounds like fucking bliss. When can you get that to me?

Given the risk - and many months of what can charitably be termed "inconvenience" - what are the alternatives to signing up for nine months of incubator duty? Let's find out. More »

Where Is My Medical Tricorder?

Reader Juan asks:

If not the medical tricorder from Star Trek, when could we possibly see diagnostic equipment capable of scanning for infections, viruses or impending heart attacks, attached to wrist watches or other portable devices?

Nothing against the phaser, but for many of us the most coveted piece of away team equipment is the tricorder, the medical version of which can perform a complex examination in a single whistling pass over a patient. If you've ever tried to lie perfectly still in a thumping MRI machine or sat in a doctor's office waiting for lab results, you've longed for faster, more portable diagnostic devices. More »

Forget the Jetpack - Where Are My Replacement Organs?

Welcome to Ask a Biogeek, a column about cutting-edge biology by UC Berkeley researcher Terry Johnson. Knowing which organs you can live without is all well and good, but wouldn't you rather have replacement organs? Tissue engineers already have some pretty good ones if you happen to lose your skin or severely damage your bones. And there are some other organs we're cooking up for you too, as long as you can hold out for a few more years. More »
