Newly Discovered War Machines in the Immune System
A newly discovered defense against pathogens involves armor and bullets that render an attacker immobile and self-destructing.
If Nanomotors Are Designed, Why Not Biomotors?
Physical chemists are justifiably proud of their tiny motors that do little more than spin. How can they say that much more complex motors in life evolved?
Membrane Channels Show Astonishing Specificity
The “selectivity filters” in membrane channels of living cells are able to discriminate between very similar molecules or atoms using complex mechanisms.
Protein Folds Violate Evolutionary Expectations
Protein folds show more flexibility than previously thought, but the flexibility appears designed. If it’s hard to get one fold to work, how about two in the same protein?
