Sweden's Karolinska Institute says a leading stem cell scientist accused of unethical behavior has been cleared of scientific misconduct though he sometimes acted without due care.

Researchers have for the first time created and used a nanoscale vehicle made of DNA to deliver...
One more reason to watch the waistline: New research says people's weight in middle age may influence not just whether they go on to develop Alzheimer's disease, but when.
Researchers have reported the first evidence that obstructive sleep apnea contributes to a breakdown of the blood–brain barrier, which plays an important role in protecting brain tissue.
A new study says that the reward center in brains of obese people may react to cravings stimuli similar to an addiction, unlike the brains of healthy weight adults.
A genetic test that helps predict whether some women’s breast cancer will recur might influence how chemotherapy is used, according to a new study.
Tumors are notoriously difficult to study in their natural habitat – body tissues – but a new synthetic tissue environment may give cancer researchers the next-best look at tumor growth and behavior. Researchers have developed a new technique to create a cell habitat of squishy fluids, called hydrogels, which can realistically and quickly recreate microenvironments found across biology.
Degenerating neurons in patients with Alzheimer’s disease (AD) measurably responded to an experimental gene therapy in which nerve growth factor (NGF) was injected into their brains.
For first time, model captures both shape and speed of tumor growth.
A tiny, wireless pacemaker could offer some heart patients a surgery-free alternative to the traditional devices, a new study says. Some doctors, however, say there are lingering safety questions and warned patients not to rush to get the new technology.
The study, led by researchers from the University of Texas Medical Branch at Galveston (UTMB), was recently published in the journal Laboratory Investigation.

A large group of researchers set out to repeat 100 experiments published by leading psychology journals to see how often they would get the same results. The answer: Less than half the time.
A defect in how proteins are transported inside cells may be at least partially responsible for some symptoms of amyotrophic lateral sclerosis, according to a new study.
Young adults diagnosed with attention deficit/hyperactivity disorder (ADHD) in adolescence show differences in brain structure and perform poorly in memory tests compared to their peers, according to new research.
Inside a tumor, immune cells and cancer cells battle for survival. The advantage may go to the cells that metabolize the most glucose, say researchers who have identified a new way to boost immune response by metabolically “rewiring” immune cells.
