3D-printed 'bionic skin' could give robots the sense of touch

Engineering researchers have developed a revolutionary process for 3D printing stretchable electronic sensory devices that could give robots the ability to feel their environment. The discovery is also a major step forward in printing electronics on real human skin.

Adolescence is thought to be the time when children go off exercise - but a study in The British Journal of Sports Medicine suggests it happens much earlier, around the age of seven.

Sitting is replacing physical activity from the time children start school, the research suggests.

Children should get at least an hour of exercise a day.

An Ovarian Cyst is defined as any collection of fluid surrounded by thin wall within o***y, which is larger than about 2 cm. Ovarian Cysts occur in women of all ages and more frequently in females of childbearing age.

Ovarian Cysts are of two types :

Functional Ovarian Cysts : These are part of normal menstrual cycle and can arise from any part playing a role in the cycle. For example Ovarian Follicles are a normal part of the ovaries playing major role in menstrual cycle. However an Follicle larger than 2 cm is termed as an Ovarian Cyst. Other examples are Thecal Cysts and Corpus Luteum Cysts.
Non-Functional Ovarian Cysts : These cysts do not arise from the female menstrual cycle. They can arise due to several other reasons, for example, Ovarian Cysts arising in Polycystic O***y Syndrome.


Cause of Ovarian Cyst

Ovarian Cysts can arise from a number of reasons. Most common reason however is as follows :

As the Ovarian Follicle matures inside the o***y during a normal menstrual cycle, it grows in size. On the day of ovulation it ruptures and releases the egg outside to be carried to the Uterus via Fallopian tubes. However if it fails to rupture it forms a fluid filled structure with a thin wall covering and hence a Follicular Ovarian Cyst is formed.

Other reasons for formation of Ovarian Cysts are :

Corpus Luteum is formed from ruptured follicle. If its size is more than 3 cm it is classified as Ovarian Cyst.
Hormone abnormality may lead to formation of Thecal Cysts and Polycystic O***y Syndrome.
Endometriosis is proliferation of Uterine wall outside Uterus and it may result in formation of Ovarian Cysts.

Signs and Symptoms of Ovarian Cyst

Ovarian Cysts are mostly functional and harmless. Signs and Symptoms associated with the Ovarian Cysts are :

Abdominal Pain
Uterine Bleeding
Rupture of Ovarian Cyst can cause sudden sharp pain on one side of the lower abdomen.
Nausea and Vomiting
Fatigue and Headaches are common
Heaviness, Pressure or Bloating etc in the abdomen
Difficulty in Urination
