Explaining consciousness is one of the hardest problems in science and philosophy. Recent neuroscientific discoveries suggest that a solution could be within reach – but grasping it will mean rethinking some familiar ideas. Consciousness, I argue in a new paper, may be caused by the way the brain generates loops of energetic feedback, similar to the video feedback that "blossoms" when a video camera is pointed at its own output.

Trauma may rank alongside tobacco use, binge drinking, and overeating as a potential risk factor for cardiovascular disease (CVD) in lesbian and bisexual women, new research suggests. Among more than 500 sexual-minority women, childhood trauma, including abuse and parental neglect, was as an independent risk factor for diabetes, increasing the odds by 58%.
Yelp reviews reveal that emergency departments are viewed as being higher quality but lacking in service as compared to urgent care centers, which patients rate the opposite, according to a new study from researchers in the Perelman School of Medicine at the University of Pennsylvania.
In late 2012, 60 people died in two cities in Pakistan after drinking cough syrup to get high. Syrups from two separate manufacturers were involved. It was found that both were using an active ingredient dextromethorphan, a synthetic morphine-like compound imported from the same manufacturer in India. Indian drug authorities put a halt to production while they investigated.
Researchers have devised a way to help blood cells regenerate faster, by stimulating a particular type of stem cell to secrete growth factors that help blood cell precursor cells differentiate into mature blood cells. This could help repopulate blood cells in cancer patients who receive bone marrow irradiation.
Women who take part in breast screening have a significantly greater benefit from treatments than those who are not screened, according to a study of more than 50,000 women, led in the UK by the Queen Mary University of London.
A widely anticipated study has concluded that neither vitamin D nor fish oil supplements prevent cancer or serious heart-related problems in healthy older people, according to research presented Saturday at the American Heart Association Scientific Sessions.
The multigene classifier test ThyroSeq Version 3 (University of Pittsburg/CBLPath) shows high accuracy in diagnosing indeterminate thyroid nodules, allowing for more than 60% of patients with such nodules to avoid diagnostic surgery, according to the final results of a multicenter, double-blinded study.
Pediatric researchers studying the life-threatening blood disorder Fanconi anemia have devised a method to block the abnormal biological signals that drive the disease. This proof-of-concept finding in animals and stem cells from human cord blood may lay the foundation for better treatments for children with the rare, frequently fatal disease.
The taboo around menstrual health is still as prevalent in the society of Bangladesh as it was for many years — despite the issue concerning half of the population. These taboos emerge from an absence of proper awareness and management of menstrual hygiene, causing more complications to the already sensitive and painful occurrence.
A pioneering technique designed to spot differences between immune cells in tumors could speed the development of cancer treatments, research suggests. Scientists say the approach could be used to help doctors choose the best treatments for individual patients and predict which tumors are likely to respond to a particular therapy.
