MRI is very good at finding and pinpointing some cancers. An MRI with contrast dye is the best way to see brain tumors. Using MRI, doctors can sometimes tell if a tumor is benign (not cancer) or malignant (cancer).

Special MRI machines, now available in some hospitals, are designed just for looking inside the breast.

Cadmium Exposure and Human Health - 0 views
-
Humans normally absorb cadmium into the body either by ingestion or inhalation Dermal exposure (uptake through the skin) is generally not regarded to be of significance
-
2% to 6% of the cadmium ingested is actually taken up into the body. Factors influencing cadmium absorption are the form in which cadmium is present in the food, and the iron status of the exposed individual. In contrast, from 30% to 64% of inhaled cadmium is absorbed by the body, with some variation as a function of chemical form, solubility and particle size of the material inhaled.
-
a greater proportion of inhaled cadmium is retained by the body than when cadmium is taken in by ingestion.

Nuclear fusion hits energy milestone - Technology & Science - CBC News - 0 views
-
For the first time, fuel for a nuclear fusion reaction has generated more energy than put into it – a scientific milestone.
-
Deuterium and tritium were coated inside the capsule at the centre of this photo
-
However, he was quick to point out that because the fuel absorbed only a small amount of the energy from the lasers, there is still far more energy put into the entire process than comes out.

The adult human brain is estimated to contain from 1014 to 5 × 1014 (100–500 trillion) synapses. Every cubic millimeter of cerebral cortex contains roughly a billion of them.

Neurotransmitters are formed in a presynaptic neuron and stored in small membrane-bound sacks, called vesicles , inside this neuron. When this neuron is activated, these intracellular vesicles fuse with the cell membrane and release their contents into the synapse, a process called exocytosis.
