Sometimes cells spit out things we don’t want them to — like medications. Researchers have determined the three-dimensional structure of a tiny pump that expels, among other things, chemotherapy agents. This new knowledge could lead to the design of more effective drugs.
New software allows for ‘decoding digital brain data’ to reveal how neural activity gives rise to learning, memory and other cognitive functions. The software can be used in real time during an fMRI brain scan.
Successful results have utilized nanotechnology to improve drug therapies for HIV patients.
Researchers have found that self-guided positive imagery training can successfully combat negative emotions in our daily lives. This tool is so powerful that it also changes the way our brain functions.
Several newly discovered variants of a gene increase the risk of developing anxiety disorders. A research team aims to derive new therapies from this finding which are better tailored to the individual patients.
Just like real doctors and nurses, online health tools with good — but controlled — communication skills can promote healthier lifestyles, according to researchers. However, if their tone is conversational, these tools may lull users into a false sense of comfort, they add. In a study, people who experienced a back-and-forth interaction with an online health risk assessment website were more likely to follow the health behaviors suggested by the tool.
Regular aerobic exercise may protect the collateral circulation and lessen the severity of strokes later in life.
The results of a large study do not support the notion that prenatal and postpartum maternal depression is particularly detrimental to children’s psychological development. Instead, the most robust effects were found for maternal depression occurring during children’s preschool years.
Sex differences in heat loss responses are dependent on body size and not sex, meaning that larger individuals sweat more than smaller ones during cycle exercise in warm and tolerable conditions.
It may be difficult to remember now, but when SARS was first recognized in February 2003, people were scared. This heretofore unknown disease was killing people—nearly 10 percent of those infected with what came to be recognized as the SARS-associated coronavirus. Before the end of the year, cases were reported in 29 countries.
