'Nightmare bacteria' cases are increasing in the US

Pharmaceutical innovation saves lives. But not every "new" drug is truly new.

In two recent studies, University of Texas at Dallas researchers demonstrated how artificial intelligence (AI) and machine learning can be used to address a variety of issues from a social science policy perspective.

About 19 million American adults consume dietary fish oil supplements. These supplements, which primarily consist of the omega-3 fatty acids eicosapentaenoic acid and docosahexaenoic acid, are widely used as a remedy for chronic diseases. However, the effects of EPA and DHA supplementation on cancer risk have been inconsistent.

Neither the painkiller Tylenol nor vaccines have been shown to cause autism, the World Health Organization said on Tuesday, following comments from the US president and his administration to the contrary.

Hospitals worldwide, including Germany, face a growing problem with fungal infections, with an estimated 6 million cases and 3.8 million deaths each year. According to the World Health Organization (WHO), Candida—a common fungus most people encounter at least once in life—is a top concern. While many know it from mild, superficial infections such as thrush, Candida (especially C. auris and C. albicans) can also reach the bloodstream and cause life-threatening disease.

Mayo Clinic researchers have developed artificial intelligence (AI) tools that help identify which children with asthma face the highest risk of serious asthma exacerbation and acute respiratory infections. The study, published in the Journal of Allergy and Clinical Immunology, found the tools can detect those risks as early as age 3.

In the United States, age-related macular degeneration is a leading cause of irreversible vision loss in people who are 60 and older.

There is no scientific evidence showing that pregnant women taking the painkiller paracetamol causes autism in their children, medical experts and drug regulators have emphasized after Donald Trump claimed the two were linked.

The brain never rests: even during deep sleep or under anesthesia, it maintains rhythmic electrical activity known as slow oscillations. A team from the Sensory-motor Processing by Subcortical Areas laboratory, led by Ramón Reig at the Institute for Neurosciences, a joint center of the Spanish National Research Council (CSIC) and the Miguel Hernández University (UMH) of Elche, has discovered what determines the direction of these waves. The study, published in iScience, reveals that the key lies not in anatomical structure, as previously thought, but in the degree of neuronal excitability.

Dexterity, coordination and balance are all extremely important throughout our lives, but these skills change between early childhood and old age. At which stage of our lives do we have the best balance? Do fine and gross motor skills continue to decline with age?

Humans use lots of different types of information to make sure we don't get lost. We can look out for familiar landmarks and use our sense of direction, but we can also estimate how far we have walked.

Dental fear is an intense emotional reaction that can be characterized by anxiety, palpitations, sweating, dizziness, a feeling of unreality or nausea. It may cause some people to avoid going to the dentist, while others feel an intense urge to flee once they are there.

Maintaining balance while walking may seem automatic—until suddenly it isn't. Gait impairment, or difficulty with walking, is a major liability for stroke and Parkinson's patients. Not only do gait issues slow a person down, but they are also one of the top causes of falls. And solutions are often limited to time-intensive and costly physical therapy.

A cognitive behavioral therapy (CBT) program developed for parents whose child was born prematurely reduced harmful perceptions that their child remained medically fragile, according to a new study led by UT Southwestern Medical Center. Published in Pediatric Research, the study is the first to show that an intervention could lower parental perceptions of child vulnerability (PPCV), a critical factor in a child's development.

On Thursday 18 September 2025, a committee of the US Centers for Disease Control and Prevention (CDC) voted to recommend that children should receive multiple separate vaccines to protect against measles, mumps, rubella and chickenpox.

Mosquito-borne viruses can cause more than fevers and joint pain. In severe cases, they invade the brain, leading to seizures, encephalitis, lasting memory loss and sometimes death. But thanks to a new UCLA study, researchers have uncovered how some of these viruses breach the brain's defenses—and point toward ways of keeping them out.

The number of reported cholera cases is increasing in Darfur and more than 3,000 people across all of Sudan have died from the illness over the last 14 months of civil war, the U.N. health agency said Tuesday.

In behavioral research, it is largely assumed that people adapt their personal behavior to match the behavior of a reference group. A distinction is made between descriptive norms—the assumption that others behave in a certain way—and injunctive norms, where people believe that others expect them to behave in a certain way.
