A double amputee managed to gain full control of two robotic arms with his thoughts. Leslie Baugh had to have both of his arms amputated at shoulder level because he was involved in an electrical accident. Forty years later, he decided to participate in a trial run by scientists at Johns Hopkins University. The University’s Applied Physics Laboratory have been working on making Modular Prosthetic Limbs for 10 years.
An infection of the small intestine by the bacterium Vibrio Cholerae, causes a diarrheal disease called Cholera. This can be deadly if it is untreated within hours. Scientists have discovered that Vibrio Cholerae implants toxins into the cells around by using a tiny spear and then takes their DNA. Bacteria generally take the DNA from other cells in order to make it into their own genomes. This process is called horizontal gene transfer. The cholera bacteria brutal way of doing this.
A new study has discovered that camping can reset a person’s body clock. Our bodies sleep patterns can be disrupted because use of electrical light and less of the natural light. A study took place in a midsummer light-dark cycle in Colorado. 14 hours and 40 minutes of light, 9 hours and 20 minutes of darkness in a 24 hour period. We rely on electrical light after sunset, which contributes to our sleeping patterns. Dr.
A paper written by Kenneth Kendler of Virginia Commonwealth University shows how higher IQ is linked to a low risk to schizophrenia. Schizophrenia is a mental disorder that is severe. It involves symptoms like abnormal social behavior, paranoid delusions, and auditory hallucinations. Emotional trauma, drug use, and mainly genetic factors cause schizophrenia.
For decades, technology has progressed dramatically for the visually impaired. New ways are being thought up in order have different opportunities for those who do not have the ability to see. An example is a surgical option. Electrode arrays are placed in the retina of the eye and electrically stimulate the living retinal cells to activate a basic visual sense.
