Analysis Of Trabecular Bone In The Femur Of Hominoids

A study that examines trabecular structure throughout the distal femur of extant hominoids and test for differences due to locomotor loading regime. In addition to external bone shape and cortical bone thickness and distribution, the distribution and orientation of internal trabecular bone across individuals and species has yielded important functional information on how bone adapts in response to load.

In particular, trabecular bone analysis has played a key role in studies of human and nonhuman primate locomotion and has shown that species with different locomotor repertoires display distinct trabecular architecture in various regions of the skeleton.

Astronauts Health Risk Of Living On The Moon

A new study showed that Astronauts returned from the Moon, they experienced a number of physiological effects such as sore throats and watering eyes; symptoms that soon earned the title of “lunar hay fever.” With a renewed interest in setting up a lunar base for mining purposes and as a platform for launching interplanetary missions to Mars and beyond, the Moon is back in fashion again. 

Electron Microscopy Reveals A Brain's Structure

Researchers describe a method based on artificial neural networks that is able to reconstruct entire nerve cells with all their elements and connections almost error-free from image stacks. This milestone in the field of automatic data analysis could bring us much closer to mapping and in the long term also understanding brains in their entirety.

The function of the brain is based on the connections between nerve cells. In order to map these connections and to create the connectome, the "wiring diagram" of a brain, neurobiologists capture images of the brain with the help of three-dimensional electron microscopy

Patient's Family Hesitant To Tell About Safety In ICU

Prior studies that when all clinical care team members are empowered to speak-up their performance improves. With the growing importance of patient- and family-centered care, patients and their families are a crucial component of the modern care team, as they can provide unique insight and knowledge into the discussion. More than half of patients and families expressed discomfort about raising patient safety concerns to the healthcare team. The study was published in BMJ Quality and Safety.

Mathematics Help For Sleepless Nights

Researchers concerned about disruptions in the body’s day/night cycle, often called its circadian rhythm, are increasingly turning from the sleep lab to mathematics to work out thorny problems in how best to handle jetlag, shift work, and weekend lifestyle patterns.

The research draws on known factors influencing circadian rhythms and sleep, such as the effect of light, caffeine, napping, and even an increasingly sophisticated understanding of the body’s circadian pacemaker, a group of about 20,000 nerve cells in the hypothalamus, a tiny region of the brain that controls a number of important metabolic processes.
