New optogenetics process could lead to neurological enhancements and treatments | KurzweilAI | Science | Scoop.it
An advanced process for precision control of cellular calcium ion (Ca2+) channels in living organisms has been engineered by a research team at the Korea Advanced Institute of Science and Technology (KAIST) and the IBS Center for Cognition and Sociality.

Calcium ions are a crucial part of diverse cellular functions such as contraction, excitation, growth, differentiation and death. Severe Ca2+ deficiency is linked to cardiac arrhythmia, cognitive impairment, and ataxia.

Do social networks make us lazy thinkers? - Futurity

Do social networks make us lazy thinkers? - Futurity | Science | Scoop.it
Our social networks help us solve problems, but that reliance can get in the way of independent analytical thinking.
Katja Bier's insight:

It is a good thing that we can solve problems by working together - problems that took a long time to solve. Yet...what will happen if new problems/issues arise - who will start the tinking process? I guess it is of immense importance to learn how to be critical with the solutions given by social interactions/networks but also to understand how the problem was solved in order to apply it to new problems.

3D-printing may revolutionize medical education

3D-printing may revolutionize medical education | Science | Scoop.it

A kit of 3D-printed anatomical body parts could revolutionize medical education and training, according to its developers at Monash University.

Professor Paul McMenamin, Director of the University’s Centre for Human Anatomy Education, said the simple and cost-effective anatomical kit would dramatically improve trainee doctors’ and other health professionals’ knowledge and could even contribute to the development of new surgical treatments.

 

“Many medical schools report either a shortage of cadavers, or find their handling and storage too expensive as a result of strict regulations governing where cadavers can be dissected,” he said.

 

“Without the ability to look inside the body and see the muscles, tendons, ligaments, and blood vessels, it’s incredibly hard for students to understand human anatomy. We believe our version, which looks just like the real thing, will make a huge difference.”

 

The 3D Printed Anatomy Series kit, to go on sale later this year, could have particular impact in developing countries where cadavers aren’t readily available, or are prohibited for cultural or religious reasons.

 

After scanning real anatomical specimens with either a CT or surface laser scanner, the body parts are 3D printed either in a plaster-like powder or in plastic, resulting in high resolution, accurate color reproductions.

 

Further details have been published online in the journal Anatomical Sciences Education.

Take a look at several domesticated mammal species and you might spot a number of similarities between them, including those cute floppy ears.
