Hypnosis can be an effective means for treating phobias, managing stress and anxiety, and even for managing pain, but all people are not hypnotized equally. New research from Stanford suggests that about one quarter of people cannot be hypnotized, and using functional and structural MRI scientists there think they’ve figured out why.
The U.S. Army tallied 38 confirmed or suspected suicides among its ranks last month--that’s among both active- and non-active-duty members including the Army National Guard and Army Reserve--the highest rate of suicide within the branch yet observed, further underscoring a mental health crisis that the services have yet to get a handle on. But help may be coming in an unlikely form: nasal spray.
DNA extracted from canned human brains could help researchers studying mental health disorders, if scientists can figure out how to mine it. Preserved brains taken from autopsied patients — some dating to the 1890s — could serve as a new archive of old data related to mental health.
Super-entities are not just limited to dominance of the globe. Just as the economy is intertwined and largely controlled by a small and powerful core network, so too is your brain. Researchers have long known that some areas of the brain are deeply connected to other regions — but now a team from Indiana University and the Netherlands says these connected brain regions form strong connections to each other, creating a cerebral “rich club.”
Studying mental illnesses involves complex brain-monitoring technology to watch how neurons and large-scale brain components are functioning or malfunctioning. But researchers are increasingly getting out of their patients’ heads, monitoring brain cells in petri dishes instead. This is possible with stem cells, and it could yield plenty of new avenues for psychiatric research.
The brain is a difficult place to wander around without a map. But while the human brain, with its billions of neurons, is far too vast a frontier for us to map using current means, researchers have been building a cell-by-cell detailed map of the neural pathways in the brains of fruit flies, shedding light on how the neurons in our own brains connect and function.
There's a lot of misinformation blowing around out there concerning the medical benefits, and detriments, of smoking marijuana, but two UK researchers are making an argument for why you should perhaps pass on the puff-puff -- as well as why recreational use should not be outlawed in the future.
With nearly 1.8 million U.S. soldiers having rotated through Iraq and Afghanistan and another troop escalation expected in coming weeks, researchers are doing double-time to define the causes of Post Traumatic Stress Disorder (PTSD) to better serve troops returning from war. With two wars going and no end in sight, scientists have quite an abundance of subjects on which to carry out their research.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
