The functioning of the human brain goes far beyond a bunch of cells packed together; each of them is able to produce, receive, and transform electrical signals into a concrete response that affects the neighboring cells, counted by hundreds. This […]

Disruption of normal blood flow to vital organs such as the heart, lung, and brain is the main cause of death in adults in the Western world. Current therapies require hospital facilities, since clot-lysing drugs are administered systemically or through […]

It is common to think that sci-fi writers are extremely creative and smart when they depict alien creatures with weird (and usually disgusting) ways of reproducing, generally using for this purpose the bodies of incautious and often naïve human characters. […]

The organism that causes flu is the influenza virus. It belongs to the family Orthomyxoviridae and they are included in Group V of the Baltimore classification, consisting in negative sense, single-stranded RNA viruses. Within this family there are […]

Proteins are sophisticated machines that perform most of our cellular activities. Proteins are codified in the cellular DNA and synthesized as linear chains that need to get properly folded in a 3D structure to become functional. This state is […]

Diabetes is a metabolic disorder characterized by an inefficiency to respond to the glucose requirements of the body, a process largely regulated by the popular hormone known as insulin. Insulin is produced and secreted in a specific type of […]
