Dopamine, a brain chemical long associated with pleasure, motivation and reward-seeking, also appears to play an important role in why exercise and other physical efforts feel “easy” to some people and exhausting to others, according to results of a study of people with Parkinson’s disease led by Johns Hopkins Medicine researchers.

Researchers have completed the most advanced brain map to date, that of an insect, a landmark achievement in neuroscience that brings scientists closer to true understanding of the mechanism of thought.

Johns Hopkins Medicine researchers are collaborating with NASA to send human heart “tissue-on-a-chip” specimens into space as early as March. The project is designed to monitor the tissue for changes in heart muscle cells’ mitochondria (their power supply) and ability to contract in low-gravity conditions.

From Alexa to a robot running amok in the movie 'M3GAN', artificial intelligence is part of everyday life and is capturing our imagination. Johns Hopkins AI expert Rama Chellappa helps us sort out fact from fiction, and whether we should embrace the 'AI spring'.

Researchers from Johns Hopkins have created and preliminarily tested what they believe may be one of the first models for predicting who has the highest probability of being resistant to COVID-19 in spite of exposure to SARS-CoV-2, the virus that causes it.

There is a certain class of pediatric brain cancers that is “universally deadly,” with a median survival of 15 months and few, if any, viable treatment options. The key to combating these cancers might be in analyzing how the cells within tumor tissue—cancer cells, immune cells, and others—express genes and organize themselves spatially.

An intensivist at Johns Hopkins Medicine, in collaboration with Johns Hopkins University engineering students, report they have developed artificial intelligence (AI) algorithms that can detect the early warning signs of delirium and can predict — at any time during an ICU stay — a high risk of delirium for a significant number of patients.

Johns Hopkins Medicine researchers say they found that old mice were less capable than young mice of “turning off” certain actively firing brain cells in the midst of ambient noise.

Scientists at Johns Hopkins Medicine say they have developed a computer model — dubbed quantitative fate mapping — that looks back in the developmental timeline to trace the origin of cells in a fully grown organism.

Two new models could solve a problem that’s long frustrated millions of people with epilepsy and the doctors who treat them: how to find precisely where seizures originate to treat exactly that part of the brain.

Johns Hopkins computational biologist Steven Salzberg says controversial Boston University study that created a potentially deadly form of the omicron coronavirus variant should never have happened.

Researchers design a protein that can activate and increase the number of specialized cells that can prevent the onset of autoimmune disorders.

Researchers from Johns Hopkins Medicine have discovered that the organization of different types of immune cells within pancreatic tumors is associated with how well patients with pancreatic cancer respond to treatment and how long they survive.

Fat inside the heart, a possible after effect of heart attacks, is a large player in the development of heart rhythm disturbances.

Johns Hopkins University and Howard University are teaming up to develop medical devices to diagnosis, treat, and manage neurological disorders.

The pulse oximeter is now a staple in hospital rooms and personal medicine cabinets. But a major flaw in its design could prevent people of color from receiving the care they need.

An algorithm built to assess scar patterns in patient heart tissue can predict potentially life-threatening arrhythmias more accurately than doctors can.

The new JHU + Amazon Initiative for Interactive AI will advance machine learning, computer vision, natural language understanding, and speech processing while increasing access to these technologies.

A group of Johns Hopkins University scientists has collaborated with more than 100 researchers around the world to assemble and analyze the first complete sequence of a human genome, two decades after the Human Genome Project produced the first draft.

Digital, personalized replicas of patients' hearts can help health care providers to better predict who will need implanted defibrillators over time.

Through advances in biomaterials, stem cell science, and more, researchers are moving tantalizingly close to regenerating damaged body parts, creating new organs, and equipping our existing tissues to fight off debilitating diseases.

Johns Hopkins Medicine researchers have developed a color-coded test that quickly signals whether newly developed nanoparticles deliver their cargo into target cells.

Johns Hopkins Medicine scientists have used glowing chemicals and other techniques to create a 3D map of the blood vessels and self-renewing “stem” cells that line and penetrate a mouse skull.

Sridevi Sarma, associate professor in the Department of Biomedical engineering, and Khalil Husari, associate professor in the Department of Neurology, have received a technology development grant through the Louis B. Thalheimer Fund for Translational Research.

AbMeta Therapeutics, launched by biologist and Provost Denis Wirtz, bioengineer Jamie Spangler, and clinician Elizabeth Jaffee, will combine years of pioneering research to target metastasis.

Johns Hopkins University scientists have developed a new tool for predicting which patients suffering from a complex inflammatory heart disease are at risk of sudden cardiac arrest.
