High protein foods boost cardiovascular health, as much as quitting smoking or getting exercise
Eating foods rich in amino acids could be as good for your heart as stopping smoking or getting more exercise -- according to new research.

Methanotrophs: Could bacteria help protect our environment?
New insight into methanotrophs, bacteria that can oxidise methane, may help us develop an array of biotechnological applications that exploit methane and protect our environment from this potent greenhouse gas.

Embryonic stem cells controlled with light
Researchers have for the first time developed a method to precisely control embryonic stem cell differentiation with beams of light, enabling them to be transformed into neurons in response to a precise external cue.

Fertilization discovery: Do sperm wield tiny harpoons?
Could the sperm harpoon the egg to facilitate fertilization? That’s the intriguing possibility raised by the discovery that a protein within the head of the sperm forms spiky filaments, suggesting that these tiny filaments may lash together the sperm and its target.

Algorithm helps identify elusive genes that express like clockwork
An algorithm is giving scientists a new way to identify the dynamics of oscillatory genes, which play an essential role in development functions like cell division, circadian rhythms and limb formation.

Batting practice in the genome
In the biochemical game of genetics, it was thought that the proteins controlling gene regulation in animals were either spectators or players. But scientists have now found that spectator proteins are actually practicing up for the big game.

Adaptive mutation mechanism may explain some forms of antibiotic resistance
Evolutionary theory says mutations are blind and occur randomly. But in the phenomenon of adaptive mutation, cells can peek under the blindfold, increasing their mutation rate in response to stress. Scientists have observed that an apparent 'back channel' for genetic information called retromutagenesis can encourage adaptive mutation to take place in bacteria.
