Microbiota poised for diagnostic and therapeutic roles in clinics within 5–10 years, says expert

Earned sick leave—short-term, paid time off for employees who are sick or injured or must care for sick or injured family members—has been found to reduce the spread of infectious diseases in the workplace and increase employee access to preventive care.

There are more than 100,000 people on organ transplant lists in the U.S., some of whom will wait years to receive one—and some may not survive the wait. Even with a good match, there is a chance that a person's body will reject the organ. To shorten waiting periods and reduce the possibility of rejection, researchers in regenerative medicine are developing methods to use a patient's own cells to fabricate personalized hearts, kidneys, livers, and other organs on demand.

A study conducted at the Botucatu School of Medicine at São Paulo State University (FMB-UNESP) in Brazil has shown that low-dose vitamin D supplementation can increase the effectiveness of chemotherapy treatment in women with breast cancer. The results suggest that the substance could be an alternative to hard-to-access drugs that also aim to increase the response to chemotherapy.

The Korea Research Institute of Standards and Science has developed a detachable acoustic lens that allows for easy adjustment of the focal length in ultrasonic inspection equipment. Much like swapping lenses on a DSLR camera to improve image quality, this technology enables users to optimize the resolution of ultrasonic imaging systems for specific inspection tasks. The innovation is expected to significantly enhance accuracy in both medical diagnostics and industrial safety inspections.

Although psychosomatic medicine is regarded as a branch of psychiatry in many countries, some of its diagnostic concepts are not fully encompassed by mainstream psychiatric diagnostic systems. When these two systems are integrated, the interrelationships among various diagnoses and their associations with psychopathologies remain to be elucidated.

Scientists say they have new experimental evidence of a novel role for bilirubin, a natural yellow pigment found in the body, in protecting humans from the worst effects of malaria and potentially other infectious diseases. The findings could advance the search for drugs that mimic the pigment bilirubin, or deliver it to the body to help protect people from severe forms of some infections.

The human body is naturally equipped with defenses to fight off viral infections. For a virus to successfully infect it, it must first overcome these defenses. To do so, viruses have evolved specialized tools—proteins known as "virulence factors"—that help them shut down or dodge the immune system and cause disease.

The architecture and processes underlying visual word recognition represent some of the most intricate systems in human cognition. The seemingly simple act of reading a word involves not only a complex interplay between cognitive layers but also relationships between the word's spelling, phonology, and meaning.

It is well known that both scarcity of resources and expectations of efficacy influence preferences and decisions in health care. But how do these two factors (scarcity and expectations) affect when both are combined? Why, for example, were specific groups of patients (mainly elderly and disabled) so obviously discriminated against during the COVID-19 pandemic, when medical resources were particularly scarce?

Regulatory authorities issued precautionary recommendations following the ORAL Surveillance trial, which demonstrated an elevated risk of cancer with tofacitinib, compared to TNF inhibitors (TNFi).

Social determinants of health (SDH), such as socioeconomic status and educational background are factors that are increasingly recognized as critical contributors to health outcomes in chronic diseases. Understanding how certain factors impact different rheumatic and musculoskeletal diseases (RMDs) is important, and new research into this for both systemic lupus erythematosus (SLE) and inflammatory arthritis was presented at the EULAR 2025 congress in Barcelona.

New research from SUNY Polytechnic Institute introduces an innovative, eco-friendly method to enhance the performance and longevity of titanium-based dental implants, focusing on improving the biocompatibility and mechanical resilience of Ti-6Al-4V alloy implants using hydroxyapatite (HA) coatings derived from biowaste.

Two RIKEN researchers have used a scheme for simplifying data to mimic how the brain of a fruit fly reduces the complexity of information about smells it perceives. This could also help enhance our understanding of how the human brain processes sensory data.

A combination therapy that adds a recently approved drug to the current standard of care for newly diagnosed acute myeloid leukemia (AML) showed high rates of complete remission in an early-phase clinical trial conducted at UNC Lineberger Comprehensive Cancer Center and 11 other sites nationwide.

Festival season can be surprisingly physically demanding. Hours spent standing, walking or dancing can put extra strain on the heart, especially for those with preexisting conditions such as heart disease, high blood pressure or diabetes, explains Gosia Wamil, M.D., Ph.D., a cardiologist at Mayo Clinic Healthcare in London.

A new study reveals striking international differences in how doctors approach the sensitive issue of tracheostomy invasive ventilation (TIV) for patients with amyotrophic lateral sclerosis (ALS). Cultural norms and health care systems appear to significantly influence physician attitudes and, consequently, patient choices regarding this life-sustaining treatment.

An international study published today in the New England Journal of Medicine sheds light on acute normovolemic hemodilution, also known as ANH, a blood conservation technique.

A study led by the Sant Pau Research Institute (IR Sant Pau) has succeeded in describing, for the first time in detail, the structural evolution of the medial temporal lobe (MTL) regions across the clinical stages of Alzheimer's disease in people with Down syndrome. The results, published in the journal Brain, reveal that volume and cortical thickness loss in these regions can begin 13 to 15 years before the onset of symptoms, marking a significant advance in early diagnosis and the design of preventive clinical trials.
