Its called Doxycycline-induced esophageal ulcer. Its not common. I have been taking Doxy for many years for acne without any complication. Then one night I took a single pill, drank half a glass of water, and went to bed. I woke up with mild heartburn. A few days later, I was in immense pain. I felt burning up and down my whole chest. I was bloated, gassy, and couldnt burp. The pain was so severe, it caused me have a migrane. The pill dissolved in my esophagus, and caused an ulcer. It was my fault for not drinking a full glass of water, and going straight to bed. Im in treatment now, and am scheduled for an esophagogastroduodenoscopy. Im feeling a little better already after the first day of treatment, but ulcers take 4-8 weeks to heal.

In the seas, kelp forests made their first appearance and soon became one of Earth's most productive ecosystems. Water from the Atlantic Ocean poured in through the Strait of Gibraltar to deluge the Mediterranean Basin. The event is called the Zanclean flood. Parts of of southern Norway and southern Sweden that had been near sea level rose to form the Hardangervidda plateau and the South Swedish highlands.

Shorty after, the glaciations, uplift of the Rocky mountains and Panama seaway closure began to reshape the Earth.

Changing the sequence of nucleotides in the DNA molecule can change the amino acids in the final protein, leading to protein malfunction. If insulin does not function correctly, it might be unable to bind to another protein (insulin receptor).

Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. ... When energy is needed by the cell, it is converted from storage molecules into ATP.
