...he flagella. They named the process intraflagellar transport (IFT). These initial observations led to biochemical and genetic studies showing that molecular motors controlled movement of the IFT particles. When the motors were stopped, flagella would not form, and already-formed flagella became shorter. The...

Vaccine-producing 'plant-factories'

...entficas (CSIC) has discovered a new route for the transport of proteins in plant cells, a discovery that will enable the biotechnological design of plant factories. Amongst other applications, these can be used to produce oral vaccines which, upon being ingested, will be able to immunise against diseases. Mor...

Researchers show that veins stiffen as we age

... connect the arteries to the veins. The veins then transport the blood back to the heart. The veins are equipped with valves to prevent any backflow of blood caused by gravity as blood is returned to the heart from the lower extremities. The walls of the veins are made of collagen and elastin, two proteins th...

It is interesting to note that the results with HSP25 were similar to those observed with amifostine, an FDA-approved radioprotective drug. However, differences did exist: only amifostine protected all components of salivary fl...

Giant insects might reign if only there was more oxygen in the air

...ts don't breathe like we do and don't use blood to transport oxygen. They take in oxygen and expel carbon dioxide through holes in their bodies called spiracles. These holes connect to branching and interconnecting tubes, called tracheae, Kaiser explained. Whereas humans have one trachea, insects have a whol...
