Certain Secrets Found To Repair Our Bones

A study found that genes could be activated in human stem cells that initiate biomineralization, a key step in bone formation. The study was appeared in the journal Advanced Functional Materials and has been the result of the combined effort from three institutions.The supercomputers Stampede1helped scientists model how the cell membrane protein receptor called integrin folds and activates the intracellular pathways that lead to bone formation. The research will help larger efforts to cure bone growth diseases.

TBI: Heavy drinkers with this history do not have worse drinking behavior

Head injury, which often damages brain regions overlapping with those involved in addictive behaviors, does not worsen drinking behavior in people with heavy alcohol use, according to a new study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. The study, led by Dr. Andrew Mayer et al. found that combining head injury with heavy alcohol use did not further alter the structure or function of the brain.

Nematocytes of Jellyfish Pack a Powerful Pressure

The stinging cells of jellyfish, called nematocytes, have evolved to be one of the world's most efficient predation tools. The nematocysts consist of a capsule and folded tubule, and use high pressure and acceleration for defence and locomotion and, more importantly, to capture prey. Inconsistencies in a previous conceptual explanation of the stinging cell mechanism were identified using a microfluidic system and mathematical models.

Newly Developed Ultra-thin Diamond Membrane Could be a Radiobiologist's Best Friend

The researchers from the Université de Bordeaux, Center National de la Recherche Scientifique, and CEA-LIST has developed an ultra-thin diamond membrane that can measure the number of protons in a radiation dose with almost perfect accuracy. The detector attaches to a charged-particle microbeam and enables the delivery of radiation to an area less than 2 micrometers wide. The study, published in Applied Physics Letters, represents a valuable technological advance for radiation biology.

Laughter: The Best Medicine for Cancer Patients

The analysis led by Lancaster University suggests that spontaneous humor is used and appreciated by people with cancer and can be a helpful way of dealing with distressing, taboo or embarrassing circumstances. People can use humorous metaphors (figures of speech) to empower themselves by undermining the illness, mocking it and distancing themselves from it.
