Warning labels on medications about the dangers of driving don't stop people from getting behind the wheel, according to Dr Tanya Smyth, from the Queensland University of Technology   Centre for Accident Research&Road Safety.

Driving while affected by prescription and over-the-counter medications had the potential to be as dangerous as driving under the influence of illegal drugs. Medication warning labels and accompanying pharmacist advice were the primary method to control drug driving but required the user to self-assess their impairment.

Evolution had a few more drinks once again, according to a new paper in Proceedings of the National Academy of Sciences which wants to prompts a rethink of what it means to be an animal.

Jellyfish, those commonplace sea pests with stinging tentacles, have actually evolved over time into "really weird" microscopic organisms, made of only a few cells, that live inside other animals.

Genome sequencing confirms that myxozoans, a diverse group of microscopic parasites that infect invertebrate and vertebrate hosts, are actually are "highly reduced" cnidarians -- the phylum that includes jellyfish, corals and sea anemones.

If you're a man, how much you eat may have more to do with the gender of your dining companions than your appetite, according to a paper published in Evolutionary Psychological Science which claims that men will eat significantly more food in the company of women than they will with other men. 

If a tumor is like a seed, the soil around it plays a significant role in its growth, according to a study which finds that the microenvironment of a tumor cell has significant impact on cancer metastasis. This discovery by Siyuan Zhang at the University of Notre Dame and a team at the University of Texas MD Anderson Cancer Center has focused attention on fighting cancer in the tumor cell's microenvironment.

As the 20th-century novelist Joseph Conrad famously wrote, "It's only those who do nothing that make no mistakes, I suppose," and Nature is very busy, so she makes lots of them. But as a genius, she can use them to advantage. Take for example whole genome duplication -- an error in DNA replication, or mating between different species, that doubles the number of chromosomes, leading to a duplication of the vast majority of genes. Such grand mistakes turn out to be among the major forces accelerating evolution.

Human brains exhibit more plasticity, the tendency to be modeled by the environment, than chimpanzee brains, which may account for part of human evolution, according to a study which may provide insight into why humans are capable of adapting to various environments and cultures. The stud examined the inherited genetic factors of brain organization in humans compared to their closest living relatives.

The research team studied 218 human brains and 206 chimpanzee brains to compare two things: brain size and organization as related to genetic similarity. The study found that human and chimpanzee brain size were both greatly influenced by genetics.
