Werner Heisenberg's 'Uncertainty Principle'(1927) is a fundamental concept in quantum physics, basically saying you can be increasingly accurate in position or momentum (mass X velocity), but not both(1).  

This can be an important feature rather than a defect in something like quantum cryptography, where information is transmitted in the form of quantum states such as the polarization of particles of light.

A group of scientists from LMU and the ETH in Zurich say they have shown that position and momentum can be predicted more precisely than Heisenberg's Uncertainty Principle states - if the recipient makes use of a quantum memory that employs ions or atoms.

Chaos is the disorder of a dynamical system but it is not completely unpredictable.   Researchers are convinced that locating the origin of chaos and watching it develop might allow science to predict, and perhaps counteract, outcomes.

Like having a heart attack. 

Writing in in the journal CHAOS, researchers say chaos models may someday help model cardiac arrhythmias (abnormal electrical rhythms of the heart) and help to understand the behavior of ventricular fibrillation, a severely abnormal heart rhythm that is often life-threatening, in order to mitigate it.
Benguela-goby, or bearded goby, is a fish species that has adapted to a hostile environment poisonous to most other organisms.  

This little goby-fish (Sufflogobius bibarbatus) reaches a maximum length of 13 cm and is only found in the Benguela ecosystem, the anoxic continental shelf outside Namibia and South-Africa,  and one of the world’s most productive fisheries areas.   Since the collapse of the sardine fisheries, this goby has become the new predominant prey species for larger fish, birds and mammals in the region.
Genes specific to sex change rapidly but there is one sex-specific gene so vital its function has remained unaltered throughout evolution and is found in almost all animals, according to new research from Northwestern University Feinberg School of Medicine.

The gene, called Boule, is responsible for sperm production and they say that Boule appears to be the only gene known to be exclusively required for sperm production from an insect to a mammal. 
Superstition may work if you think it works.   If only voodoo were so easy, we'd love to have an army of zombies at our command.

But people, and certainly athletes, maintain any number of superstitious rituals, so Lysann Damisch, Barbara Stoberock and Thomas Mussweiler of the University of Cologne designed a set of experiments to see if activating  people's superstitious beliefs would improve their performance on a task.  Their research says that having some kind of lucky token can actually improve performance – but by increasing self-confidence and not any magical mojo.
A new study says it is the first to identify a life-or-death "cell competition" process in mammalian tissue that suppresses cancer by causing cancerous cells to kill themselves. 

Central to their discovery was the researchers' identification of 'Mahjong,  a gene that can determine the winners of the competition through its close relationship with another powerful protein player.
