Hidden Sensory System Under the Skin

The human sensory system is more complex than previously thought, according to a new study and published in he journal, "Pain". The sensory network is located throughout the human blood vessels and sweat glands. The skin has many different nerve endings that distinguish between different temperatures, types of mechanical contact (vibrations, movement and etc). The new research indicates that these nerve endings appear on blood vessels and sweat glands as well. Yet there is another type of mental sensory feedback which remains as a mystery.

New Wound Dressing helps Infections from Burns

Statistically, 70% of all people die from infections after severe burns, but a new wound dressing developed at Tel Aviv University could cut that value dramatically. The dressing has fibres that is loaded with drugs like antibiotics to speed up the healing process and dissolve when complete, while eradicating infection causing bacteria. The technology is complex, even though the concept is simple. The wound dressing must maintain a certain level of moisture while acting as a shield and it must allow fluids to leave the wound at a specific rate.
