"Chemotherapy is brutal. The goal is pretty much to kill everything in your body without killing you."
That's what Rashida Jones said in Oprah Magazine back in 2009 while discussing her mother's cancer.

And it's true. While chemotherapy has been one of our greatest weapons in fighting cancer, it can be merciless to the person who has to go through it. Side effects include hair loss, pain, fatigue, trouble concentrating, and stomach issues. It can even sometimes cause long-term damage to your heart, lungs, or other organs.
That's why researchers have devoted a ton of time to trying to create better, more precise, less-like-dropping-a-bomb-into-your-veins treatments.
And researchers in Canada, led by professor Sylvain Martell of the Polytechnique Montréal Nanorobotics Laboratory, might have just created something amazing – a kind of remote-controlled anti-cancer nanorobot. They published their findings in a paper titled "Magneto-gerotactic Bacteria Deliver Drug-containing Nanoliposomes to Tumour Hypoxic Regions."
Yeah, it's a mouthful, but the science behind it is pretty cool and not actually that hard to understand. Here's how it works:
Imagine your body's blood vessels like a gigantic hamster maze.

I know, kind of a weird metaphor, but stick with me here. Now, there are over 60,000 miles of blood vessels in our body all stitched together, so this is a pretty big maze. And somewhere in there, connected to the system, is our target – the tumor. But how do we get to it?
Standard chemotherapy is kind of like taking a big old bottle of chemicals and trying to just flood everything.
If the tube maze is full up to the top with chemicals, that tumor's definitely going to get treated, but so will, you know, everything else connected to that maze.
So as most chemo is trying to stop cancer's runaway growth, there tends to be a good amount of noncancer collateral damage to other growing cells (that's why chemo patients tend to lose their hair).
That's the (very simplified) standard chemo scenario.
This new technique, however, is like dropping the hamster into that maze, then leading it directly to the tumor with a carrot.
Only in this case, the hamster is actually tiny ocean-going bacteria called magnetococcus. Magnetococcus is special because it has a kind of built-in compass that it uses to orient itself in the big, wide ocean. If it ever gets lost, it can use that compass to wiggle its way back home.
What the researchers figured out they can do is take some of those bacteria, load them up with special, cancer-fighting chemicals, then inject them into the patient. Then, by using computer-controlled magnets outside the patient's body, they can tweak all those mini-compasses and lead the cancer-fighting bacteria straight to the tumor, like a hamster following its nose.

It's worth noting that a few other places have experimented with other kinds of nano-delivery schemes, but they weren't as precise partly because they didn't use things that could move on their own like these bacteria can.
There's some other cool things about this particular technique as well, like how the bacteria can naturally seek out hard-to-reach areas of the tumor that don't get a lot of oxygen and how they might be able to penetrate the brain's security-system-esque blood-brain barrier.
It's still in testing, but if this works, it could make chemotherapy far less brutal.

So far they've tested it in mice, and the researchers have obtained funding to try to put together a fully-equipped, human-sized setup. The government of Quebec even kicked in $1.85 million.
Chemotherapy is a life-saving invention, and it'd be hard for me to overstate how much it's changed cancer treatment. But anyone who's taken it or anyone who's watched a loved one go through it can tell you it's rough. Thanks to researchers like these, treating cancer one day might be a heck of a lot easier.

An Irish woman went to the doctor for a routine eye exam. She left with bright neon green eyes.
It's not easy seeing green.
Did she get superpowers?
Going to the eye doctor can be a hassle and a pain. It's not just the routine issues and inconveniences that come along when making a doctor appointment, but sometimes the various devices being used to check your eyes' health feel invasive and uncomfortable. But at least at the end of the appointment, most of us don't look like we're turning into The Incredible Hulk. That wasn't the case for one Irish woman.
Photographer Margerita B. Wargola was just going in for a routine eye exam at the hospital but ended up leaving with her eyes a shocking, bright neon green.
At the doctor's office, the nurse practitioner was prepping Wargola for a test with a machine that Wargola had experienced before. Before the test started, Wargola presumed the nurse had dropped some saline into her eyes, as they were feeling dry. After she blinked, everything went yellow.
Wargola and the nurse initially panicked. Neither knew what was going on as Wargola suddenly had yellow vision and radioactive-looking green eyes. After the initial shock, both realized the issue: the nurse forgot to ask Wargola to remove her contact lenses before putting contrast drops in her eyes for the exam. Wargola and the nurse quickly removed the lenses from her eyes and washed them thoroughly with saline. Fortunately, Wargola's eyes were unharmed. Unfortunately, her contacts were permanently stained and she didn't bring a spare pair.

Since she has poor vision, Wargola was forced to drive herself home after the eye exam wearing the neon-green contact lenses that make her look like a member of the Green Lantern Corps. She couldn't help but laugh at her predicament and recorded a video explaining it all on social media. Since then, her video has sparked a couple Reddit threads and collected a bunch of comments on Instagram:
“But the REAL question is: do you now have X-Ray vision?”
“You can just say you're a superhero.”
“I would make a few stops on the way home just to freak some people out!”
“I would have lived it up! Grab a coffee, do grocery shopping, walk around a shopping center.”
“This one would pair well with that girl who ate something with turmeric with her invisalign on and walked around Paris smiling at people with seemingly BRIGHT YELLOW TEETH.”
“I would save those for fancy special occasions! WOW!”
“Every time I'd stop I'd turn slowly and stare at the person in the car next to me.”
“Keep them. Tell people what to do. They’ll do your bidding.”
In a follow-up Instagram video, Wargola showed her followers that she was safe at home with normal eyes, showing that the damaged contact lenses were so stained that they turned the saline solution in her contacts case into a bright Gatorade yellow. She wasn't mad at the nurse and, in fact, plans on keeping the lenses to wear on St. Patrick's Day or some other special occasion.
While no harm was done and a good laugh was had, it's still best for doctors, nurses, and patients alike to double-check and ask or tell if contact lenses are being worn before each eye test. If not, there might be more than ultra-green eyes to worry about.
