You have a bigger brain than your ancestors – and that’s good news.
A new study published in Jama Neurology shows that human brain size has been steadily increasing in people born after 1930. The average volume is more than six percent greater, and the brains surface area has increased by nearly 15 percent. The researchers think that these larger brains may reduce the cases of age-related brain conditions like dementia, since it has more capacity to adapt to any changes. (UC Davis)
New research unveils another mystery of Alzheimer’s disease.
A study published in Lancet Neurology reveals that the condition starts earlier and progresses much faster in people with down syndrome. In fact, almost all adults with down syndrome will show signs of Alzheimer’s by late middle age. Despite this, there are no current treatments specifically for people with down syndrome and they’re often excluded from clinical trials. (Washington University in St. Louis)
Can we reverse antibiotic resistance?
Scientists are trying to find out how to use our current medications more efficiently and effectively, instead of developing new drugs to fight the resistance. As part of this mission, new research in Nature Communications has discovered how resistant genes spread so fast. They duplicate and jump from strain to strain, helping each one form a resistance to new drugs. (Duke University)
