Have you ever sucked back a huge glob of cough syrup and then waited in bed, still hacking, and thought to yourself, “Is it working yet?” According to a video created by the American Chemistry Society’s Reactions YouTube channel, you’re not alone. According to Reactions, there is no conclusive scientific evidence that over-the-counter cough syrup works at all.

Reactions came to this conclusion by analyzing systematic reviews which compared data from multiple studies. This meta-analysis found there’s very little evidence that cough syrup is effective at treating coughs. Clinical trials also show that these medications generally do no better than a placebo. In one systematic review, 15 out of 19 studies showed there was no benefit to using cough syrup or the results were conflicting. Also, popular remedies echinacea, vitamin C or zinc haven’t been found to reduce coughing either.

Reactions did provide three tried-and-true methods to reduce coughing:

1.) Drinking plenty of fluids will help thin out excess mucous and reduce your cough reflex

2.) A humidifier or steamy shower can help reduce congestion

3.) Cough drops will increase saliva production to soothe your irritated throat

As with any medical advice, consult your doctor before putting it to practice.

There's new hope for people with liver disease.

Scientists are developing breakthrough bioprinted liver tissue that could buy patients life-saving time

There are more than 100 types of liver disease, according to the American Liver Foundation. And per the Gift of Life Donor Program, patients who need a liver transplant face a national average wait time of about 11 months. Now, however, new hope is emerging from the scientific community at Carnegie Mellon University.

In early January 2026, researchers at CMU received an award of up to $28.5 million from the Advanced Research Projects Agency for Health (ARPA-H) to develop a functional, 3D-bioprinted liver transplant for patients with acute liver failure. That investment already appears to be paying off, as researchers are closer than ever to developing living liver tissue made from human biological material.

There are no ‘good’ or ‘bad’ foods when thinking holistically about health.

A dietitian explains how flexibility can be healthier than only dieting

Eat this, not that. This one food will cure everything. That food is poison. Cut this food out. Try this diet. Don’t eat at these times. Eat this food and you’ll lose weight. With society’s obsession with food, health and weight, statements like these are all over social media, gyms and even health care offices.

But do you need to follow rules like these to be healthy? Most often the answer is no, because health and nutrition is much more complex and nuanced than a simple list of what to eat and what to avoid. Despite this, rules about health and nutrition are so common because of diet culture – a morality imposed by society that sees falling outside the arbitrary ideal of thinness as a personal failure. Diet culture and the people promoting it expect you to pursue or maintain thinness at all times.

Mel Robbins reveals the 6 'magic words' she says will stop anxiety in its tracks

Anxiety is a natural biological response and a very normal part of being human. With breaking news, an evolving economy, pressures for job performance, and basic family dynamics, anxiety has become a more common challenge.

That's why simple tools that reframe racing thoughts have gained in popularity. Motivational expert, author, and host of one of the world's biggest podcasts Mel Robbins revealed six "magic words" that can help stop anxiety in its tracks: "What if it all works out?"

Two in five Americans have fought with a family member about politics, according to a 2024 study by the American Psychiatric Association. One in five have become estranged over controversial issues, and the same percentage has “blocked a family member on social media or skipped a family event” due to disagreements.

Difficulty working through conflict with those close to us can cause irreparable harm to families and relationships. What’s more, inability to heal these relationships can be detrimental to physical and emotional well-being, and even longevity.

Malaria researchers are getting closer to outsmarting the world’s deadliest parasite

Every year, malaria kills more than 600,000 people worldwide. Most of them are children under 5 in sub-Saharan Africa. But the disease isn’t confined to poor, rural areas – it’s a global threat that travels with people across borders.

For decades, the fight against malaria has felt like running in place. Bed nets and drugs save lives, but the family of parasites that cause malaria, called Plasmodium, keeps evolving new ways to survive. These parasites transmitted to humans through the bites of infected mosquitoes.

Psychologist offers imaginative tip on how to tolerate insufferable people with grace

It can be hard to get through the day, especially if you’re in a good mood and someone else is bringing you down with anger and negativity. It’s not just annoying to hear, but it can really bring down your mood or get you involved in their drama. Fortunately, one way to help yourself in such situations is to just be a tree.

Psychologist Kimberly Moffit went on TikTok to offer some imaginative advice for the next time someone tries to rage-bait you in real life. She advises that you picture yourself as a tall, calm tree and the angry person as a small gremlin trying to light you on fire with their angry “sparks.” Instead of getting lit up in flames, just let the sparks bounce off you and land back on the ground. The idea is that the “gremlin” will eventually move on after seeing that their “sparks” didn’t faze you.

New study suggests compassion, patience, and self-control are great 'selfish' choices for your own happiness

Virtues such as compassion, patience and self-control may be beneficial not only for others but also for oneself, according to new research my team and I published in the Journal of Personality in December 2025.

Philosophers from Aristotle to al-Fārābī, a 10th-century scholar in what is now Iraq, have argued that virtue is vital for well-being. Yet others, such as Thomas Hobbes and Friedrich Nietzsche, have argued the opposite: Virtue offers no benefit to oneself and is good only for others. This second theory has inspired lots of research in contemporary psychology, which often sees morality and self-interest as fundamentally opposed.

Neurologist explains why 'novelty' is a brilliant workout for your brain's health

If you have ever lifted a weight, you know the routine: challenge the muscle, give it rest, feed it and repeat. Over time, it grows stronger.

Of course, muscles only grow when the challenge increases over time. Continually lifting the same weight the same way stops working.
