Big improvement to brain-computer interface

Fri, 17/02/2017 - 2:59pm
Researchers have developed an improved type of electrode that is more durable, lasts longer in the body and transmits a clearer, more robust signal than electrodes made from current state-of-the-art materials. This could allow for improved restoration of mobility after spinal cord accidents, as well as improved powered prosthetic limbs.

New research examines gun use, injury and fear in domestic violence

Fri, 17/02/2017 - 2:59pm
About 2 percent of domestic-violence incidents involve guns, according to new research. Victims of these crimes typically have fewer injuries but more fear. These findings come as part of her latest work, which looks at how frequently guns and other weapon types appear in domestic-violence incidents.

Tumor suppressor promotes some acute myeloid leukemias, study reveals

Fri, 17/02/2017 - 2:59pm
A tumor suppressor protein thought to prevent acute myeloid leukemia (AML) can actually promote a particularly deadly form of the disease, researchers have discovered. The study suggests that targeting this protein could be an effective treatment for certain AML patients.

ICU care for COPD, heart failure and heart attack may not be better

Fri, 17/02/2017 - 2:59pm
Does a stay in the intensive care unit give patients a better chance of surviving a chronic obstructive pulmonary disease (COPD) or heart failure flare-up or even a heart attack, compared with care in another type of hospital unit? Unless a patient is clearly critically ill, the answer may be no, according to researchers who analyzed more than 1.5 million Medicare records.

DNA computer brings 'intelligent drugs' a step closer

Fri, 17/02/2017 - 2:59pm
Researchers present a new method that should enable controlled drug delivery into the bloodstream using DNA computers. The team developed the first DNA computer capable of detecting several antibodies in the blood and performing subsequent calculations based on this input. This is an important step towards the development of smart, 'intelligent' drugs that may allow better control of medication with fewer side-effects and at lower cost.

Peer milk-sharing participants generally keep it clean

Fri, 17/02/2017 - 2:59pm
Mothers who want the benefits of breast milk for their babies but can't produce the substance often turn to milk-sharing networks. A new study has found that although not a recommended practice, those who participate in milk-sharing networks generally follow good hygiene, which is critical for keeping milk free from bacterial contamination.

Right-handed or left-handed: Why?

Fri, 17/02/2017 - 2:59pm
It is not the brain that determines if people are right or left-handed, but the spinal cord, new research indicates. The biopsychologists have demonstrated that gene activity in the spinal cord is asymmetrical already in the womb.

Is the human brain hardwired to appreciate poetry?

Fri, 17/02/2017 - 2:58pm
In 1932 T.S. Eliot famously argued, 'Genuine poetry can communicate before it is understood.' But can we really appreciate the musical sound of poetry independent of its literary meaning? Apparently yes. A recent study has shown that the brain displays a positive electrophysiological response when presented with sentences that conform to certain poetic construction rules. It is the first demonstration of unconscious processing of poetic constructs by the brain.
