Amazing Ice Cubes in Lake

In the winter, for about five months or from January to May, the (Lake Baikal Russia) freezes over but the water is so clear that, from the surface, you can see an astounding 130 feet below you.
Wind, temperature differences, frost and sun in the ice crust cause cracks and ice hummocks to form. Transparent and shining in a turquoise color, these masses of broken ice look like shards of glass rising into the sky.

New Born Baby

Greek Dr. Aris Tsigris, Obstetrician – Gynaecologist Surgeon, posted in his Facebook profile this shocking photo of a newborn baby.

Dr. Aris Tsigris comment : “A rare picture … very rarely will say …. birth after caesarean, with the bag intact, the baby still has not understood that he was born ….. it is like it is still in the womb,the phenomenon is known as ”birth veil” and birth is more common but equally rare in premature births, total occlusion of the newborn in the bag, do not leave the baby drowned in the amniotic fluid, because it begins to breathe immediately after removing the” veil”, as the placenta continues to feed the baby with blood, the nature overcomes itself, leaving breathless even obstetricians … “.

Magic Mushrooms ~ Cookeina Speciosa

Cookeina is a genus of cup fungi in the family Sarcoscyphaceae, members of which may be found in tropical and subtropical regions of the world. Species may be found on fallen branches of angiosperms, trunks, and sometimes on fruits. The Temuans of Peninsular Malaysia are reported to use certain species from this genus as food,
and also as a bait for fishing, where it is rubbed against the hook.

When mature apothecia become filled with water, the asci absorb some of that water and develop a Turgor pressure, a hydrostatic pressure within the ascus which put pressure on the tip of the ascus, held in place by the rigid ascus wall. As the water level in the cup reduces due to evaporation, the asci tips dry out, resulting in a negative vapor pressure that ultimately results in the thin tissue at the wall of the apex (the operculum) breaking outward, releasing the spores

Protective Cases of Caddisfly Larvae

Caddisflies are an order (Trichoptera) of insects with approximately 12,000 described species. They can be described as small moth-like insects with two pairs of hairs membranous wings. One of the most interesting characteristics of the caddisfly is the ornate and highly intricate protective cases they build as larvae.
The caddisfly larvae is aquatic and can be found in a variety of habitats such as streams, rivers, lakes, ponds, springs and even temporary waters. The larvae collects whatever material it can to form its protective case, bonding the various materials together with silk that it excretes from its salivary glands near its mouth. [Source]
Different species of caddisfly tend to use different materials for their protective cases making for a diverse array of cases. Artists have even taken it a step further, cultivating their own cadisfly and providing them with unique building materials like gold and pearls to create ornate protective cases that are preserved for their artistic merit after the cadisfly has undergone metamorphosis.
