The human immune system is very complex. A large number of different cells with various functions ensure that invading microorganisms such as viruses...
The centuries-long search for the fountain of youth has yielded only a few promising leads, one of which entails an extreme, emaciating diet. A new...
Biologists at UC San Diego have found the "missing link" in the chemical system that enables animal cells to produce ribosomes -- the thousands of...
Think of the human body as an intricate machine whose working parts are proteins: molecules that change shape to enable our organs and tissues to...
A UNSW-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum...
Humans tend to think of the flow of time in the context of evolution and biology as a fairly consistent thing [1]. We are used to the conceptual...
How does a stem cell decide what path to take? In a way, it’s up to the wisdom of the crowd. The DNA in a pluripotent stem cell is bombarded with...
Nanopores may one day lead a revolution in DNA sequencing. By sliding DNA molecules one at a time through tiny holes in a thin membrane, it may be...
It's broadly assumed that cells degrade and recycle their own old or damaged organelles, but researchers at University of California, San Diego...
