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."

Pedro Pascal and Bowen Yang can't keep a straight face as Ego Nwodim tries to cut her steak.

Most episodes of “Saturday Night Live” are scheduled so the funnier bits go first and the riskier, oddball sketches appear towards the end, in case they have to be cut for time. But on the February 4 episode featuring host Pedro Pascal (“The Mandalorian,” “The Last of Us”), the final sketch, “Lisa from Temecula,” was probably the most memorable of the night.

That’s high praise because it was a strong episode, with a funny “Last of Us” parody featuring the Super Mario Brothers and a sketch where Pascal played a protective mother.

The instructors were ruthless.

If you’re not familiar with James Corden’s popular "Toddlerography" segment, you’re in for a treat.

As the name suggests, celebrity guests on “The Late Late Show with James Corden” take a dance class taught by kiddy instructors. Sure, the “students” are usually pretty seasoned performers, like Jennifer Lopez, Justin Bieber, and Jason Derulo, but their experience doesn’t make learning the moves any less intense. Anyone who’s tried to keep pace with a toddler knows it’s a helluva workout.

Billy Porter was the latest guest invited to participate in this wholesome fitness trend, and he did not disappoint.

Keanu Reeves shocks a small-town pub by stopping in for a pint and taking photos with the staff

“So today we had a surprise visitor for lunch. What a lovely man he was, too."

Keanu Reeves in São Paulo, Brazil, 2019.

Keanu Reeves has a reputation as one of Hollywood’s nicest celebrities. Recently, he cheered up an 80-year-old fan who had a crush on him by calling her on the phone. He’s also bought an ice cream cone for a fan to give an autograph on the receipt and crashed a wedding to take photos with the bride and groom.

He’s also an incredible humanitarian who gave up a big chunk of his money from "The Matrix" to a cancer charity.

The “John Wick” star was his usual gracious self over the weekend when on Saturday, February 4, he and a friend walked into The Robin Hood pub in Tring, Hertfordshire, about 30 miles outside of London.

A new mother struggling with postpartum depression.

We may be just months away from having the first-ever pill to help treat postpartum depression (PPD). The drug, called Zuranolone, was developed by Sage Therapeutics and Biogen, two companies out of Cambridge, Massachusetts. The FDA has given the drug’s application priority review and the period ends on August 5, 2023.

Currently, there is only one FDA-approved medication for PPD, Zulresso, which is only available through a 60-hour, one-time infusion and can cost up to $35,000 per treatment.

If the medication is approved, it can also be used to treat major depressive disorder (MDD).

North Carolina boy helps local bakery by selling them fresh eggs.

You don't have to be a market analyst to know that the price of eggs has skyrocketed. If you're just an average person buying eggs for breakfast, it may seem ridiculous that egg prices are so high when it appears that the local Tractor supply always has baby chicks for sale.

But with an outbreak of avian flu infecting nearly 58 million birds while people move away from meat protein and consume more eggs, the price increase makes sense. It's painful to people's budgets, but it's how the market works, and families aren't the only ones feeling the pinch.

Small businesses that rely on eggs are also experiencing their budgets busting due to egg prices. Sweet Anna's Bakery in Dallas, North Carolina, already had to raise prices due to the cost of eggs and other ingredients, but owner Courtney Johnson discovered she had a connection. Fifth grader Rylen Robbins has 21 chickens that were producing too many eggs for his family to eat. (You see where this is going, right?)

AMC announced that it would be implementing a new three-tier ticketing system.

AMC Theaters, America’s largest movie theater chain, announced on Feb 6 that it will be adopting different ticket prices based on seat location.

Moviegoers will have three tiers to choose from based on sightline of the movie screen—Preferred Sightline, set in the middle at the highest price point, Value Sightline, set in the front of the auditorium at the lowest price, and Standard Sightline, which is basically everything else (including the back seats, which are perhaps the most commonly picked) set at the traditional cost of a ticket.

In other words…heartbreak will feel more expensive in a place like this…or less, depending on where you sit



The company’s announcement was met with both criticism and approval. While some feel the move follows a well-established business model, others have found it to be taking away a valued aspect of the moviegoing experience.
