Researchers developed a tiny fart-measuring device that snaps into underwear. 

How Often Do You Fart? This ‘Smart Underwear’ Can Keep Track, Because Figuring Out a Baseline Is Important for Science

Researchers have launched a study to find a typical range for flatulence, which has been harder to measure than you might expect

This Scientist Brewed and Drank His Own ‘Vaccine Beer’ to Combat a Dangerous Virus. It Seems to Have Worked

Blood tests revealed that the beverage elicited an immune response, according to preliminary research. But far more safety and efficacy testing would be needed before this vaccine could become available

HPV testing is crucial for cervical cancer prevention, but many people miss their exams. 

Testing Menstrual Blood for HPV Might Provide a Less Invasive Way to Screen for Cervical Cancer, a New Study Suggests

While the method shows promise, some experts say that other self-collection devices are more readily available

Tobacco smoking and alcohol consumption were responsible for 15 percent and 3 percent of all cancer cases diagnosed in 2022, a new study suggests.

Nearly Four in Ten New Cancer Cases Might Be Preventable, According to the World Health Organization

A landmark global study suggests that tobacco smoking, infection and alcohol consumption are the leading causes of preventable cancers

Though still in early stages, some experts say that A.I.-supported screenings could help save patients' health, time and money.

A.I. Could Help Doctors Spot Hard-to-Detect Signs of Breast Cancer During Routine Screenings, a Clinical Trial Suggests

Standard testing can miss some tumors, which are later diagnosed and called interval cancers. They’re often more aggressive than screening-detected disease

Surgeons removed the patient's failing lungs and temporarily replaced them with an artificial version, saving his life.

Artificial Lungs Kept a Dying Man Alive For 48 Hours—Until He Was Well Enough to Receive an Organ Transplant

The patient is faring well nearly three years later, thanks to the life-saving device

The human genome is made up of about three billion pairs of DNA units called nucleotides.

Google Researchers Say Their New A.I. Tool AlphaGenome Can Help Decode the Human Genetic Instruction Book

The computer model might help scientists better understand the biological impacts of typos in DNA

Researchers traced a pathway between the heart and the brain.

After a Heart Attack, the Brain’s Response Might Make Recovery Harder. Cutting Some Communication Between the Organs Could Help

The new study in mice could lead to innovative treatments for heart attacks

Researchers studied data from nearly 125,000 pre- and post-menopausal women.

How Do Menopause and a Treatment to Manage Its Symptoms Affect the Brain and Mental Health?

New research suggests an association between menopause and anxiety, depression and shrinkage in certain brain regions—which hormone replacement therapy might not mitigate

The findings point to a mental strategy that could help bolster typical medical treatments.

Positive Thinking Might Boost Your Immune System’s Responses to Vaccines, New Research Suggests

Researchers found an association between increased activity in a reward region of the brain—primarily stimulated by hopeful thinking—and heightened levels of protective antibodies after receiving a vaccine

Through gene-editing, researchers in the field of synthetic biology hope to make endangered species more resilient against disease or climate change and protect human health, among other goals.

Three Stunning Ways Biologists Aim to Edit Animal and Plant Genes to Fight Diseases and Extinction

The strategy, known as synthetic biology, is gaining momentum globally as a conservation tool and human health solution, despite attracting some critics

Ötzi the Iceman is housed at the South Tyrol Museum of Archaeology, where conservationists periodically humidify his remains.

Ötzi the Iceman May Have Carried a Cancer-Causing Strain of HPV, a Common Virus Still Plaguing Humans Today

A new study, which also found evidence of the high-risk strain in 45,000-year-old remains, suggests HPV has evolved alongside humans for many millennia

Spaceflight Temporarily Changes the Position and Shape of Astronauts’ Brains, MRI Data Suggests

The biggest changes happen in brain regions involved with processing sensory information and coordinating movement, according to a new study

A neural circuit that processes motivation and reward seems to act as a "brake" when faced with an unpleasant task, a study suggests.

Can’t Get Started on a Daunting Task? This Brain Circuit That Slams the Brakes on Motivation Might Be to Blame

Monkey experiments hint at a “motivation brake” pathway between two brain regions. Manipulating it may lead to new treatments for depression and other psychiatric conditions

Naked mole-rats are unusual for their long lives and resistance to cancer. Now, researchers suggest the rodents not only tolerate but prefer to be in low-oxygen air.

Naked Mole-Rats Prefer Low-Oxygen Air That Would Kill Most Mammals, Adding to Their List of Death-Defying Superpowers

These underground rodents are the first mammals found to actively choose air with lower-than-normal oxygen levels. Their remarkable ability to survive these conditions could offer a key model for researchers studying new treatments for stroke or lung diseases in humans

Though the study describes only a correlational relationship, the findings reinforce the idea that sleep is important for human health. 

Not Getting Enough Sleep? You Might Be Shortening Your Life Span

In the United States, insufficient sleep strongly correlates with life expectancy, even more than diet, exercise or social connections do, a new study suggests

Researchers investigated the associations between preservatives and the risk of developing cancer and type 2 diabetes.

Eating Large Amounts of Certain Preservatives Might Increase Your Risk of Developing Cancer and Type 2 Diabetes

Two studies tracked more than 100,000 participants over 14 years to reveal the trends. But they can’t confirm a direct link between eating these preservatives and developing disease, especially because some of the additives were eaten in foods that contain known carcinogens

ChatGPT Health is a new function designed to provide users with personalized medical insights based on medical records and health data uploaded by users. 

OpenAI Says ChatGPT Health Can Understand Users’ Medical Data and Provide Personalized Answers to Their Questions

The new feature can give tailored responses based on medical records and wellness app data, according to ChatGPT’s maker. But some experts are concerned about privacy and worry that people may over-trust the chatbot

Humans have continuously lived and worked aboard the International Space Station (ISS) since November 2000.

NASA to Bring ISS Crew Home Early Because of an Astronaut’s Health Issue, Marking the First Medical Evacuation of the Spacecraft

The unnamed crew member is in stable condition after an undisclosed incident on Wednesday, but the agency is bringing them back to Earth for medical testing
