The
International Genetically Engineered Machine competition brings undergraduates from around the world to MIT's campus to share the results of a summer's worth of synthetic biology research. Each team tries to create the best synthetic organism. Here you can see the iGEM participants (photo courtesy of David Appleyard and iGEM). I'm one of the folks in black up in front. (No, the other one.) Find out what these students cooked up over the summer, and who won.

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.

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.

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.

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.

Welcome back to Ask a Biogeek, a column where you ask biology researcher Terry Johnson any question you want — no matter how weird. Reader Charlie writes:
How about an article on the current cutting edge cancer research/treatments? Is there anything out there that is promising? Will there be a cure in our lifetimes?

Welcome to Ask a Biogeek, a column where you ask UC Berkeley researcher Terry Johnson any question you want — no matter how weird. Reader Matthew asks:
This is an odd question, but is there anything we're certain isn't coming? Most of my friends are all starry-eyed optimistic sci-fi readers, and they continually bombard me with what will be the "future of the human species" . . . from "meat vats" for growing cruelty free meat to clone armies. Anyway, is there anything that is solidly stymied at this point? Any futurist direction we know is blocked?

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?

Welcome to Ask a Biogeek, a column where you ask UC Berkeley researcher Terry Johnson any question you want — no matter how weird. Reader Mairi proxies the following question:
My mom wants to know when we're going to get needle-less, painless injections. While I personally covet the
medical tricorder, I would almost prefer that my doctor have a
hypospray - Starfleet's painless, needle-free injection system. The concept of a high-pressure alternative to a syringe dates back to
The Shadow's radio show, and medical devices that function accordingly exist today. These, however, are not the only potential alternatives to a painful jab.

Welcome back to Ask a Biogeek, a biweekly column where UC Berkeley biology researcher Terry Johnson answers your questions, no matter how weird. Reader Mike asks:
Can you speculate on what a silicon based lifeform might look like? What would an "organic chemistry" look like for silicon, instead of carbon?

Spore
Last week Electronic Arts was kind enough to invite me to a demonstration of
Spore's
creature creator. A few days ago,
we told you about Spore, a video game that challenges you to guide a single cell on the bottom of the evolutionary ladder out of the ocean and into civilization. (Here you can see my creature,
Chlorophyta complexus chainsawus - AKA the Chlororaptor.) It's not easy for a video game to teach the principles of evolution. Evolutionary games would necessarily be limited to pressing start and watching what happens as mutation and selection occur, without intervention from the player. Spore strikes a good balance between scientific fact and playability.

It's another installment of Ask a Biogeek, a column where UC Berkeley biology researcher Terry Johnson answers all your questions — especially the weird ones. Reader Daniel wonders:
As a biologist who studies whole organisms and populations, I find that more and more of biology (in terms of funding, positions and emphasis) is going to the sub-organismal level. We now have lots of cell biologists, geneticists, neurologists, biochemists, biomechanics, bioengineers and so on, but not a lot of behaviorists, population ecologists, biodemographers and others who study the emergent properties that arise at the higher levels of organization. What role, if any, do you foresee for understanding of these higher level biological phenomena in the future sci-fi-ish stuff?
I believe we're rapidly reaching the point where scientists will be both ready and able to consider artificially-induced emergent biological properties — in other words, terraforming. Let me take you on a tour of today's state-of-the-art in this emerging field.

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.

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.

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.

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.
