Humans trust dogs to help find missing people and bees to pollinate their crops. But scientists still don't fully understand how these animals use their extraordinary sense of smell to locate the source of an odor.

An international study finds that older adults who have strong beliefs about how other seniors should behave also report having more memory problems themselves.

Researchers at the University of Colorado Anschutz Cancer Center have identified a previously unknown metabolic weakness in the stem cells that drive high-risk myelodysplastic syndromes (MDS), a discovery that could lead to more targeted treatments for this aggressive blood cancer.

Researchers at McMaster University have discovered that a naturally occurring hormone best known for suppressing appetite and promoting weight loss also helps protect the liver from inflammation through a previously unknown signalling pathway, opening new possibilities for treating advanced fatty liver disease.

Baylor College of Medicine today announced that a new research agreement with United Therapeutics Corporation, a public benefit corporation, will provide up to $5 million a year for five years to establish the Baylor College of Medicine Center for Xenoliver Transplantation and Immunomodulation (XTI), dedicated to advancing scientific understanding of xenoliver transplantation.

Researchers at Weill Cornell Medicine have uncovered how a key Parkinson's protein called LRRK2 shifts between inactive and active forms, revealing the structural changes that enable certain mutations to push the protein into an overactive state.

A team led by researchers from the German Cancer Research Center (DKFZ), the HI-STEM Stem Cell Institute, and Medical Clinic V at Heidelberg University Hospital (UKHD) has characterized T cells in the bone marrow in cases of multiple myeloma and acute myeloid leukemia: A specific group of tumor-reactive T cells can recognize and, in principle, fight cancer cells, but is often not sufficiently activated.

A new nationwide study finds antiviral treatment is linked to fewer intensive care unit (ICU) admissions and shorter hospital stays for children hospitalized with influenza.

A new study led by researchers at the University of Pittsburgh found that women living in socially vulnerable communities face a 20% higher risk of death after an ovarian cancer diagnosis compared with women living in less vulnerable communities.

The brain evidently can regenerate itself better than previously assumed after injuries or certain autoimmune diseases.

A joint research team led by Professor Sungsu Park of Sungkyunkwan University and Professor Sun-Ha Paek of Seoul National University College of Medicine has demonstrated for the first time that the sequence in which immune cells interact with cancer cells can critically influence the therapeutic response in glioblastoma.

Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases.

Spinal cord injury begins with immediate mechanical damage, but much of the lasting neurological loss develops during the secondary phase, when inflammation, oxidative stress and disrupted metabolism continue to injure surviving tissue.

LUAD is the most common histological subtype of lung cancer. Although surgery can be curative for patients diagnosed at an early stage, approximately 30%-50% develop recurrence or aggressive metastasis within five years.

After treatment for metastatic prostate cancer, a drop in prostate-specific antigen (PSA) levels in the blood is an indicator that the treatment is working.

A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.

Every year, more than 120,000 newborns worldwide contract HIV, a global health burden that requires lifelong treatment for millions of people - assuming they have access and can afford it.

The world-first trial of a fridge-free tetanus-diphtheria vaccine at University Hospital Southampton (UHS) has produced encouraging results that could improve access worldwide to crucial treatments.

Doctors may think they're saying "Don't panic." But many patients hear "Don't bother" instead.

In a US cohort of 52,971 adults with type 2 diabetes and established atherosclerotic cardiovascular disease, tirzepatide initiation was associated with a lower one-year risk of major adverse cardiovascular events than sitagliptin. The benefit was driven mainly by lower myocardial infarction and all-cause mortality hazards, although the authors cautioned that mortality findings may be influenced by residual confounding.
