How our minds trick us into thinking we are being greener than we really are

A new method to keep human lymph node tissue alive and functioning outside the body for several days could give researchers a much clearer view of how our immune system responds to infections, vaccines and cancer, without the need for preclinical modeling or over-simplified laboratory models.

Two-thirds of clinical trial participants treated with psilocybin-assisted therapy for major depressive disorder were in complete remission from their depression five years later, a new study has found.

Patients have more confidence in autonomous robotic ultrasound systems when an avatar guides them through the process. This is reported in a new study by Prof. Nassir Navab from the Technical University of Munich (TUM). The virtual agent explains what it is doing, answers questions and can speak any language. Such systems are intended especially for use in regions where there is a shortage of doctors.

More women than ever are carrying babies conceived with someone else's egg—but few are told that this might carry greater health risks.

Standard blood tests can help physicians predict the risk of mortality in patients with drug reaction with eosinophilia and systemic symptoms (DRESS), a rare but potentially life-threatening reaction to certain medications. Due to its severity, early recognition and risk assessment are critical.

CenteringPregnancy is a prenatal care model combining education and individual health assessments in group settings for women at similar stages of pregnancy. A new evaluation by the Rutgers School of Public Health demonstrates that Centering fosters important social ties among expectant parents and provides opportunities for developing greater trust between health care providers and patients.

When the lungs are attacked by a virus, the damage doesn't stop there. The body's natural defenses cause inflammation while fighting the virus, often leaving lasting problems. The cells that make up the lungs' mucosal lining are exposed to the environment with every breath—both highlighting the risk of infection and emphasizing the need for a robust response.

Antiphospholipid syndrome is an autoimmune disease that impacts about one in every 2,000 individuals.

Bipolar disorder, also known as "manic-depressive illness," a brain disorder known to have afflicted the famous painter Vincent van Gogh, is characterized by recurrent episodes of mania and depression.

Doctors' offices were once private. But increasingly, artificial intelligence (AI) scribes (also known as digital scribes) are listening in.

A new study from MIT neuroscientists reveals how rare variants of a gene called ABCA7 may contribute to the development of Alzheimer's in some of the people who carry it.

Small cell lung cancer cells that metastasize to the brain cozy up to neurons and form working electrical connections, called synapses, according to a study led by Stanford Medicine researchers. The pulse of electrical signals to the cancer cells strongly promotes tumor growth, the researchers found.

Researchers have found that the presence of certain bacteria in the maternal gut microbiome during early pregnancy is linked to a higher risk of preterm birth. Published in the journal Cell Host & Microbe on September 10, the study reports that one particular species, Clostridium innocuum (C. innocuum), contains a gene that can degrade estradiol—an important pregnancy hormone.

It's natural to crave sugar when you feel tired and want a boost of energy. Now scientists at Columbia University's Zuckerman Institute have linked a brain area in mice to the drive to consume not just sweets, but fats, salt and food. The findings show this area serves as a kind of dial that can amplify or repress consumption.

A quicker, cheaper MRI scan was just as accurate at diagnosing prostate cancer as the current 30–40 minute scan and should be rolled out to make MRI scans more accessible to men who need one, according to clinical trial results led by UCL, UCLH and the University of Birmingham.

Lung tumors don't just evade the immune system. They reshape it at its source. Researchers from the Icahn School of Medicine at Mount Sinai and collaborators report in the September 10 online issue of Nature that tumors rewire immune cells in the bone marrow before they even reach the cancer, suggesting a new target to enhance the durability of current immunotherapy.

Men, black communities and the poorly educated are experiencing significant disparities in accessing game-changing digital health care for type 2 diabetes, data scientists from The University of Manchester show.

When a critically ill baby with dextro-transposition of the great arteries (D-TGA) was transferred to Children's Hospital Los Angeles last year—just hours after birth—the Heart Institute team saw right away that the case was anything but routine.
