Childbirth used to be a terrifying ordeal. But women were surrounded by others – mothers, aunts, sisters – who brought love and experience. But midway through the 19th century, this changed.
Sulfur pollution causes respiratory health problems.

Sulfur contaminates gasoline and coal, and when these fuels are burned, sulfur dioxide is emitted, causing pollution and respiratory issues. Now there may be a new, cheaper way to remove it.
Suicide is a growing health problem.

Suicide is the second leading cause of death for teens in America. But there may be ways to study the stress response and figure out who is most at risk.
Alfred Nobel made his fortune through the invention of dynamite.

Oxygen is vital for life, so much so that cells can sense when there isn’t enough and adapt almost instantly. So how do they do it? The winners of the 2019 Nobel Prize for Physiology figured it out.
Low blood pressure may cause problems for many older people.

Researchers are looking for ways to determine who’s most at risk for dementia and also ways to detect it early. A scientist who has studied low blood pressure makes a case for a link between the two.
Drinking alcohol isn’t the only cause of high blood alcohol levels.

When people get sick, they often suspect bacteria and viruses as the cause. But now the CDC is asking physicians and patients to consider another culprit: fungi.
Are eggshells the next supermaterial for tissue engineers?

Bioengineers who are trying to grow replacement human tissues and organs are at the forefront of biomedicine. But you may be surprised by some of the materials they are using for this endeavor.
Bill Maher suggests that fat-shaming may help people lose weight.

Fat-shaming is as ineffective as it is cruel. The bullying tactic also ignores the biological factors underlying obesity, which are not always under a person’s control.
New research suggests that a newborn is exposed to bacteria and fungi in the womb.

Nearly half of patients with congestive heart failure who are hospitalized and then discharged end up back in the hospital within 90 days. Could a toilet seat help prevent this from occurring?
Apothecaries of the 17th and 18th centuries diagnosed illness, mixed up medicine and dispensed it, a far cry from the current turf war between doctors and pharmacists.

The ‘turf war’ between doctors and pharmacists we see in current debates has a long history.
Currently, stem cell based treatments are still mostly experimental, and while some results are encouraging, several clinical trials have failed.

Stem cells show much promise, both for testing drugs and for treating disease. But the hype around them has been dangerous, as most treatments are in very experimental stages and can cause harm.
Csilla Ari D`Agostino and her teammate carry out experiments outside their undersea habitat.

How is NASA preparing astronauts for high-stress living on the Moon? Turns out the answer is by living in undersea bases just off the coast of Florida in a lab known as Aquarius Reef Base.
Scientists are working with artificial intelligence in hopes of being able to better detect cancer.

Are more technologically advanced prosthetics and orthotics actually better for improving health? Or do we just think they are better? And most importantly, how do we figure it out?
Lab-grown organs may not be so easy to transplant into a patient.

The idea behind regenerative medicine is that the patient is both the donor and recipient of healthy tissue grown from stem cells. But sometimes the transplanted cells are rejected. Now we know why.
Inhaling mist contaminated with Legionella pneumophila can lead to Legionnaires’ disease.

A woman recently died from Legionnaires’ disease at an Atlanta hotel. Why? The cause is known and the disease is largely preventable. Yet the number of cases in the US continue to rise.
Obesity is one of the risk factors for non-alcoholic fatty liver disease.

Almost all drugs are tested in living animals before human clinical trials. But most of the time what works in mice doesn’t work in humans. That’s why lab-grown human livers may be so valuable.
