AI-based evaluation of medical imaging data usually requires a specially developed algorithm for each task. Scientists have now presented a new method for configuring self-learning algorithms for a large number of different imaging datasets – without the need for specialist knowledge or very significant computing power.

A new approach to cancer therapy shows potential to transform the commonly used chemotherapy drug gemcitabine into a drug that kills cancer cells in a specialized way, activating immune cells to fight the cancer, according to a study. The findings were made in human and mouse cancer cells and laboratory mice.

Teens who are unhappy with their physical appearance are at significantly heightened risk of depression by the time they reach early adulthood, reveals the first UK study of its kind. The size of the increased risk ranges from 50% to 285%, the findings show, with boys more likely to experience severe depression than girls.

The Pfizer and BioNTech COVID-19 vaccine is safe, effective, and starts working within about two weeks of the first dose, according to documents published by the Food and Drug Administration. The FDA’s briefing document shows that the vaccine is 95 percent effective at protecting against symptomatic COVID-19, and there are no serious safety concerns with the shot.

Approximately 200,000 cancer patients are diagnosed with brain metastases each year, yet few treatment options exist because the mechanisms that allow cancer to spread to the brain remain unclear. However, a study offers hope for the development of future therapies by showing how a poorly understood gene known as YTHDF3 plays a significant role in the process.

Neuroscientists have taken a decisive step in the quest to understand the biology of long-term memory and find ways to intervene when memory deficits occur with age or disease. They describe a newly identified mechanism that neurons in the adult mouse hippocampus use to regulate signals they receive from other neurons, in a process that appears critical for memory consolidation and recall.

Depression is a mental disorder that affects more than 264 million people of all ages worldwide. Understanding its mechanisms is vital for the development of effective therapeutic strategies. Scientists recently conducted a study showing that an imbalance in the gut bacterial community can cause a reduction in some metabolites, resulting in depressive-like behaviors.

High-intensity interval training strengthens the heart even more than moderate exercise does. Now researchers have found several answers to what makes hard workouts so effective. Research on rats with heart failure shows that exercise reduces the severity of the disease, improves heart function and increases work capacity.

Researchers have rebuilt a human thymus, an essential organ in the immune system, using human stem cells and a bioengineered scaffold. Their work is an important step towards being able to build artificial thymi which could be used as transplants. The scientists rebuilt thymi using stem cells taken from patients who had to have the organ removed during surgery.

Climbing four flights of stairs in less than a minute indicates good heart health. This study was conducted to examine the relationship between a daily activity – i.e., climbing stairs – and the results obtained from exercise testing in a laboratory. The study included 165 symptomatic patients referred for exercise testing because of known or suspected coronary artery disease.
