The Zika virus is kind of scary.
The disease hides in mosquitoes and can be spread by a bite. And for most people, Zika's symptoms are pretty mild — a little joint pain and maybe a fever.
But for some folks, the symptoms might be more severe. Some victims may develop the potentially fatal Guillain-Barré syndrome. And most perniciously, if a pregnant woman is infected, the virus can cause a serious birth defect known as microcephaly in her unborn child.

Althought the disease has been around since the 1940s, it's been gaining attention lately after being newly introduced in South America.
The World Health Organization declared a public health emergency in February 2016 because of Zika's quick spread.

And the pope even suggested contraceptives could be used to slow its spread — a big gesture from the leader of the Catholic Church.
But we just had a major breakthrough in fighting off this disease: a vaccine.

On June 20, 2016, Inovio Pharmaceuticals and GeneOne Life Science announced that the U.S. Centers for Disease Control and Prevention have given them permission to test an experimental vaccine on human subjects.
This would be the first Zika virus vaccine.
This is just the first step in fighting Zika, but it's an exciting one.
The companies will start the process by giving the vaccine to a small group of 40 people to see if the drug is safe and tolerable for patients to take. This test will also be their first chance to see how effective it is for humans. (Previous animal studies showed promise, but that doesn't always translate to humans.)
Granted, there's still a ways to go. Depending on the test results, it could be a few years before we see widespread use of a vaccine like this.
And if this vaccine works, it could help a lot of people.

As of June 2016, Zika is live and spreading in more than 60 countries, and the World Health Organization estimates that Zika could infect as many as 4 million people in North and South America by the end of 2016.
It's not being transmitted in the continental United States (although there have been about 750 travel-related infections reported), but it has been found in Puerto Rico.
On Feb. 22, 2016, President Obama requested $1.9 billion in emergency spending to help combat the virus. And Rep. Vern Buchanan, a Republican from Florida, recently announced his support of the request.
"People's lives are at stake," said Buchanan, "the time for inaction is over."
The Zika virus is kind of scary. But thanks to research like this, we may be able to beat it in the next few years.
That will be an incredible win.

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.
