Coming soon: More than one data point on the transgender experience in the military

Part of the problem with the Chelsea Manning situation is that it's spawned a lot of not-terribly-well-informed discussion about the roles and experiences of transgendered people in the military. There's a risk of this one big anecdote coming to represent the whole. Enter the Kinsey Institute — America's favorite source of sexuality science — which just got a grant to do actual research on the lives of transgender service members.

Scientists host 3-day snail rave

As part of an effort to understand the spread of a potentially deadly canine parasite, researchers at the University of Exeter put LEDs and glow-in-the-dark paint on 450 garden snails and proceeded to film them over the course of 72 hours.

The result is kind of gorgeous and mesmerizing, as tiny points of colored light meander in time lapse through the snails' natural habitat.

Besides the trippy display of gastropod activity, the researchers also learned interesting things: Like the fact that snails can cover as much as 82 feet in a day, and some snails save energy while traveling by using the slime trails left by others.

How to: Read a scientific research paper and come away smarter

Anthropologist Jennifer Raff offers this great guide, aimed at laypersons, that will help you learn more from reading the scientific research papers you find online and prevent you from succumbing to common mistakes that often show up in Internet flame wars. Step 1: Don't rely on the abstract to tell you what's going on — read the introduction first, instead.

Neurosurgeons at UC Davis censured after trying out probiotic treatments on brain cancer patients

The Sacramento Bee is reporting on a complicated story about last-ditch treatments and the ethics of human experimentation.

Glioblastomas are incredibly deadly brain cancers that usually kill the people diagnosed with them within 15 months. Two neurosurgeons at UC Davis ran across anecdotal evidence suggesting that glioblastoma patients who accidentally picked up infections after surgery sometimes lived much longer — one of the surgeons claims that a patient he knew of survived another 20 years.

Things that correlate with autism

"Things that correlate with autism" is basically an entire genre of scientific research, in and of itself, and nobody does a better job of breaking those studies down than Emily Willingham. Her latest piece is about a recent study that correlates induced labor at birth with autism diagnosis later in life.

What causes an ice cream headache?

It would take a simple experiment to prove, once and for all, what causes "brain freeze". Unfortunately/fortunately the condition isn't particularly serious, so nobody has ever gotten a grant to perform that simple study.

A big win for consent, privacy, and genome data

The family of Henrietta Lacks — a woman whose cervical cancer cells were harvested and used in scientific research for decades without her knowledge or consent — will now play a role in deciding who has access to the Lacks' cell genome data, and for what purposes. There are loopholes in the new system. For instance, the agreement only applies to scientists who receive National Institutes of Health funding. And the genome of the cells has been sequenced so many times, at this point, that anybody who wasn't NIH funded and didn't want to voluntarily abide by the agreement essentially wouldn't have to.

But it is a big step forward, both for the Lacks family (whose own genetic information is contained in those genome sequences) and for the idea that human genetic information belongs to the people it comes from — not to whoever happens to sequence it.

The happy selfie posted here features NIH director Francis Collins posing with some of Henrietta Lacks' descendants after the agreement was announced.

Help ocean scientists build open-source research tools

CTD units are incredibly important to ocean research, measuring three basic factors of sea water — conductivity, temperature, and depth. Almost every major research vessel has one. But the units are part of what ensures that it's expensive to get started doing ocean science. Each one can cost between $5000-$25,000. Now, a group of ocean scientists are trying to finance the design of an open-source CTD that could be built by anyone for less than $200. You can help fund their efforts at Rockethub.

More thoughts on lab meat

Yesterday, Rob told you about the first public tasting of a burger that was grown in a laboratory, from strips of flesh built up from muscle stem cells. I found a couple of great links today that build on that news. First: The secret ingredient in lab-grown meat is fetal cow blood. (It's both a significant part of the high price of lab meat, and a reason why your vegan friend won't be eating lab meat anytime soon.) Also be sure to check out synthetic biologist Christina Agapakis' perspective — she tones down some of the hype while making it clear why lab meat is still pretty impressive.

Why new cloned mice can help scientists treat lab animals more humanely

This week, scientists cloned a mouse from cells found in a drop of mouse blood. That's different from other cloned mice, whose creation relied on more invasive sampling from the liver, bone marrow, and lymph nodes (read: the original animal was euthanized). Cloning mice is valuable for scientific research — it's handy to have your subjects be as alike one another as possible. Now, scientists have a way to do that without having to kill the original mouse.

Independently funded studies on the safety of GM food

The Genera Project was started last summer to create an easily-searchable catalog of peer-reviewed scientific studies dealing with the risk, benefits, and safety analysis of genetically modified plants. The project isn't done yet — for instance, the "easily searchable" part isn't yet active and they aren't done cataloging the 600+ studies in the database. I thought it was worth pointing this resource out to you folks, though, especially because at least 126 of the studies currently in the database are free from questionable funding — either from big corporations or blatantly anti-GMO activist groups. Definitely a project to keep an eye on.

What happens when a drug works — but only for one person?

Really, really intriguing piece at Nature News by Heidi Ledford. It's all about a class of patients called "exceptional responders" — aka, the people who got a benefit (sometimes a big one) from a medication or treatment that otherwise failed the clinical trial process. When we do clinical trials, we're looking at group averages. We want to know whether a drug performed better than placebo when administered to lots of people. Sometimes, though, drugs that can't do that do seem to have a positive effect for a few lucky individuals. Now, scientists are trying to figure out why that is. What makes those people special? And how should this change the way we do research?

Two months aboard an Antarctic ice breaker, condensed to 5 minutes

Here's an incredibly cool video showing the prow of a massive ice breaking ship as it plows through Antarctica's Ross Sea. The footage is sped up, to pack two months of travel into five minutes. But, unlike a lot of time-lapse videos, this one also has a really informative audio track, in which marine scientist Cassandra Brooks waxes poetic about the many different kinds of ice and explains why she and her team were out there, breaking through the stuff, to begin with.

Bonus: At the end, you get to see the absolute adorableness that is penguins on high-speed fast forward.

A spaceship that tastes like Grape-Nuts

This morning, Marketplace Tech Report had a story on a new cellulose-based building material that could be made by genetically engineered bacteria — altered versions of the bacteria that naturally make stuff like kombucha. This tech sounds like it's got a long way to go from laboratory to the real world, but if they can perfect the process and make it large enough quantities, what you'd end up with a strong, inexpensive goop that could be used to build everything from medical dressings, to digital paper, to spaceships. Yes, you could theoretically use this stuff to make rocket casings, according to R. Malcolm Brown, Jr., a professor of cell biology at UT Austin. And if you can build a rocket from this stuff, you could also break the same material back down into an edible, high-fiber foodstuff.

A resurgence in LSD research

It's drug week at Popular Science and Shaunacy Ferro would like you to know why doctors can't give you LSD — and why they maybe ought to be.

Honoring death by donating your body to science

i09's Annalee Newitz is donating her body to science when she dies. In a moving and fascinating article, she tells the story of her mother's death, how it led her to make this choice for herself, and what happens to bodies once they find their way into the hands of medical schools and scientists.

Some like it cold

In a study of 6,455 semen samples (yup), scientists at Israel's Ben-Gurion University of the Negev found that human sperm were most atheletic — and were found in the highest concentrations — in winter. There was a marked decrease in sperm motility and numbers in spring, summer, and fall. It's an interesting and logical addendum to the fact that sperm counts and motility decrease in men who subject their testicles to warm conditions; in hot tubs, say, or a pair of overly tight underpants.
