Branching isn't just for trees. This biological process occurs in animal development, enabling organs to perform complex functions. Branch-like structures form in the lungs, kidneys, and breasts, among other places. Importantly, only in female mammary glands does most branching occur years after birth. It happens during puberty and again during pregnancy as milk ducts branch out in preparation for breastfeeding. Disturbances here have been linked to breast cancer. However, studying branching can be difficult and time-consuming.
Older adults with HIV are prescribed opioids at a higher rate and are more likely to have indicators of opioid use disorder than those without HIV, according to Rutgers Health researchers.
Researchers from the University of Copenhagen have developed a method that allows for the analysis of thousands of proteins in heart tissue. This provides entirely new insights into the characteristics of heart diseases and could pave the way for more targeted treatments.
Continuing angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers before non-cardiac surgery is linked to a reduced risk of postoperative mortality and functional decline, according to researchers from Science Tokyo. Using a Japanese nationwide registry of 2.6 million patients over 50 years old, the researchers compared outcomes between those who continued antihypertensive therapy and those who did not. Their findings highlight potential benefits of specific classes of antihypertensive drugs depending on the type of surgery needed.
The air we breathe might be something you don't spend a lot of time thinking about—until it impacts your day.
Students who change schools between eighth and ninth grade are more likely to drink alcohol, according to new research.
Doctors nationwide are issuing urgent warnings about a viral food trend inspired by the hit Netflix movie "KPop Demon Hunters" that is causing serious scalding injuries in children and teens.
Researchers at London Health Sciences Center Research Institute (LHSCRI) have launched a Phase II clinical trial that aims to treat renal cell carcinoma (kidney cancer) by inserting microscopic beads filled with radiation directly into blood vessels surrounding cancerous tumors. The goal is to improve patient outcomes through a new treatment option.
Researchers have found the first direct evidence that tiny particles of air pollution stick to red blood cells, meaning they can travel freely around the body.
During one of my visits to schools in Delhi, I asked the students: "When something doesn't go the way you expected, or when you fail at something, it feels bad, right? What do you say to yourself in those moments?"
The Trump administration announced on Sept. 20, 2025, that it plans to stop releasing food insecurity data. The federal government has tracked and analyzed this data for the past three decades, but it plans to stop after publishing statistics pertaining to 2024 data. The Conversation U.S. asked Tracy Roof, a political scientist who has researched the history of government nutrition programs, to explain the significance of the U.S. Household Food Security Survey and what might happen if the government discontinues it.
As a pediatrician, I thought my medical background and pediatric training meant I would be well prepared to breastfeed my newborn. I knew all about the research on how an infant's diet can affect both their short- and long-term health. Compared to formula, breastfeeding is linked to a lower risk of sudden infant death syndrome, lower rates of infections and hospitalizations and a lower risk of developing diabetes later in life. Breastfeeding can also provide health benefits to the parent.
Digestive discomfort—whether it's bloating after a heavy meal or the occasional bout of indigestion—can make anyone miserable.
A University of Alberta-led research team has identified an association between asthma in pregnant women and adverse outcomes for their newborns, including preterm birth, low birth weight and cesarean section delivery.
Adolescence is a period of social reorientation: a shift from a world centered on parents and family to one shaped by peers, schools, and broader networks. This expansion is critical for healthy development, but it also heightens susceptibility to social stressors. When those stressors lead young people to withdraw—choosing solitude more often than connection—the brain itself may be altered.
Mobile health apps could help improve health among older adults with diabetes, according to a study by researchers at the University of Georgia and University of Illinois Urbana-Champaign.
Near-death experiences can have lasting, life-changing effects, and new University of Virginia School of Medicine research sheds light on the types of counseling and support that can best help people cope.
Imagine being able to compose an email or steer a wheelchair directly with your thoughts. For millions of people living with neurological disorders such as ALS, this possibility could be life-changing. Their ability to think and feel remains intact, but the connection to the outside world is often disrupted.
Feeling good doesn't just lift our mood—it also helps us stay flexible and resilient. A new study by an international team of neuroscientists shows that natural brain opioids released after rewards play a key role in broadening attention, offering fresh insights into stress, cognition, and well-being.
