Meet the man behind a new HIV vaccine that could help end the virus for good.

Dr. Robert Gallo has spent decades aiming to end AIDS.

If there ever were a pioneer in the war on AIDS, Dr. Robert Gallo would certainly fit the bill.

That may seem like common knowledge today. But back in the 1980s — when the AIDS crisis was ravaging communities across the U.S. and very little was known about the virus — it was nothing short of groundbreaking.

He then spearheaded a blood test that can detect the virus in humans.

The blood test has had big ramifications in curbing HIV infections, as health care workers became equipped to rapidly diagnose infected patients.

And on Oct. 8, 2015, Gallo was at it again, announcing yet another big step in the fight against HIV: His potentially game-changing vaccine is going to human trial.

Sure, there are other HIV-fighting vaccines in human trial (about 30, in fact). But Gallo's vaccine, which has taken his team at the University of Maryland's Institute of Human Virology nearly two decades to produce, stands out ... in a good way.

There are many strains of HIV that can affect the immune system. And that makes creating a universal vaccine that stops all of them a bit tricky. If proven successful, however, Gallo's vaccine would protect patients' immune systems from the variations of the virus classified under "HIV-1," which constitutes the vast majority of infections worldwide.

"Our HIV/AIDS vaccine candidate is designed to bind to the virus at the moment of infection, when many different strains of HIV found around the world can be neutralized. We believe this mechanism is a major prerequisite for an effective HIV preventive vaccine." — Dr. Gallo

Enrollment in the trial opened this month, and the institute is looking for 60 people to participate in its year-long phase 1, according to The Baltimore Sun.

It's a promising step forward in the fight against a virus that's had a massive impact on global health.

There are about 35 million people living with HIV/AIDS around the world, according to the World Health Organization. About 1.5 million people died from the virus in 2013 alone. Sub-Saharan Africa — where nearly 71% of people living with HIV globally reside — has been affected far more than other regions of the world.

Although new medicines have helped HIV patients live longer, healthier lives, there is still no cure for the virus. And even for those fortunate enough to be living in regions with access to such medicines, drugs can be expensive (although that doesn't stop some greedy pharmaceutical company CEOs from inflating prices even further ... yeah, I'm talking about you, Martin Shkreli).

Gallo's vaccine could be huge. But even if it turns out to be, there are plenty of hurdles before patients can benefit.

Gallo's announcement is exciting! But let's not put the cart before the horse. Before the vaccine gets clearance from the FDA and becomes a welcomed reality for patients, it has to successfully pass a range of human trials. And that will take several years to complete.

But Gallo is confident the long road ahead will bring promising results.

"Can I promise absolute success? No," Gallo said of the vaccine's potential, according to The Baltimore Sun. "Do I hope it leads to a series of advances in the fields? Yes. And I think it will lead to some advances."

I'm staring at my screen watching the President of the United States speak before a stadium full of people in North Carolina. He launches into a lie-laced attack on Congresswoman Ilhan Omar, and the crowd boos. Soon they start chanting, "Send her back! Send her back! Send her back!"

The President does nothing. Says nothing. He just stands there and waits for the crowd to finish their outburst.

My mind flashes to another President of the United States speaking to a stadium full of people in North Carolina in 2016. A heckler in the crowd—an old man in uniform holding up a TRUMP sign—starts shouting, disrupting the speech. The crowd boos. Soon they start chanting, "Hillary! Hillary! Hillary!"

What will future generations never believe that we tolerated in 2019?

Dolphin and orca captivity, for sure. They'll probably shake their heads at how people died because they couldn't afford healthcare. And, they'll be completely mystified at the amount of food some people waste while others go starving.

According to Biological Diversity, "An estimated 40 percent of the food produced in the United States is wasted every year, costing households, businesses and farms about $218 billion annually."

There are so many things wrong with this.

First of all it's a waste of money for the households who throw out good food. Second, it's a waste of all of the resources that went into growing the food, including the animals who gave their lives for the meal. Third, there's something very wrong with throwing out food when one in eight Americans struggle with hunger.

Supermarkets are just as guilty of this unnecessary waste as consumers. About 10% of all food waste are supermarket products thrown out before they've reached their expiration date.

Three years ago, France took big steps to combat food waste by making a law that bans grocery stores from throwing away edible food.According to the new ordinance, stores can be fined for up to $4,500 for each infraction.

Previously, the French threw out 7.1 million tons of food. Sixty-seven percent of which was tossed by consumers, 15% by restaurants, and 11% by grocery stores.

This has created a network of over 5,000 charities that accept the food from supermarkets and donate them to charity. The law also struck down agreements between supermarkets and manufacturers that prohibited the stores from donating food to charities.

"There was one food manufacturer that was not authorized to donate the sandwiches it made for a particular supermarket brand. But now, we get 30,000 sandwiches a month from them — sandwiches that used to be thrown away," Jacques Bailet, head of the French network of food banks known as Banques Alimentaires, told NPR.

It's expected that similar laws may spread through Europe, but people are a lot less confident at it happening in the United States. The USDA believes that the biggest barrier to such a program would be cost to the charities and or supermarkets.

"The logistics of getting safe, wholesome, edible food from anywhere to people that can use it is really difficult," the organization said according to Gizmodo. "If you're having to set up a really expensive system to recover marginal amounts of food, that's not good for anybody."

Plus, the idea may seem a little too "socialist" for the average American's appetite.

"The French version is quite socialist, but I would say in a great way because you're providing a way where they [supermarkets] have to do the beneficial things not only for the environment, but from an ethical standpoint of getting healthy food to those who need it and minimizing some of the harmful greenhouse gas emissions that come when food ends up in a landfill," Jonathan Bloom, the author of American Wasteland, told NPR.

However, just because something may be socialist doesn't mean it's wrong. The greater wrong is the insane waste of money, damage to the environment, and devastation caused by hunger that can easily be avoided.

Policing women's bodies — and by consequence their clothes — is nothing new to women across the globe. But this mother's "legging problem" is particularly ridiculous.

What someone wears, regardless of gender, is a personal choice. Sadly, many folks like Maryann White, mother of four sons, think women's attire — particularly women's leggings are a threat to men.

While sitting in mass at the University of Notre Dame, White was aghast by the spandex attire the young women in front of her were sporting.

Men are sharing examples of how they step up and step in when they see problematic behaviors in their peers, and people are here for it.

Twitter user "feminist next door" posed an inquiry to her followers, asking "good guys" to share times they saw misogyny or predatory behavior and did something about it. "What did you say," she asked. "What are your suggestions for the other other men in this situation?" She added a perfectly fitting hashtag: #NotCoolMan.

Not only did the good guys show up for the thread, but their stories show how men can interrupt situations when they see women being mistreated and help put a stop to it.
