Segway inventor creates a Artificial Arm.

I’ve seen this one in blog.TED.com. Dean Kamen’s received a visit of a very senior government officer requesting him to invent an artificial arm according to few very simple specifications: he wanted the returing troopers of war, which had losen their arms, be able to pick a berry, and feel it size, weight and texture.

As a consequence of a SuperTech behaviour, and its ability to enhance human body, I check it both as SuperTech and HumanTech technology.

Human Tech – Caffeine may trigger Panic crisis.

Study carried on by the UFRJ, Rio de Janeiro Federal University, demonstrates that caffeine may trigger Panic crisis.

They used 480mg of caffeine, as much as 5 cups of coffee, ingested in 15 minutes. The group was composed of 40 patients either healthy or whom suffered of Panic Syndrome, depression and few other psychiatric.

Those who suffered of Panic Syndrome or depression associated to Panic Syndrome display more crisis after ingesting this ammount of caffeine than the other groups.

According to the psychiatrist Antonio Egídio Nardi, professor of UFRJ medicine school, this discovery may be used in future treatments for Panic Syndrome, he says: “With a controlled dose, it might be possible to produce a light version of crisis and help the patient to deal with them”.

Human & Nature Tech – Skin ageing ‘reversed’ in mice

Californian researchers had found a protein – NF-kappa-B – acknowledged to play a role in numerous aspects of ageing.

They managed to rejuvanate the skin of two-year old mice.

According to the leader scientist of the research, Dr. Chang from Stanford School of Medicine, these findings support the theory that ageing process is result of genetic change, therefore they could be reversed later in life.
