One of the most important molecules relating to cancer is called p53. This Click and Learn explains the structure and function of the p53 protein as well as how the protein's activity is regulated. Learn why p53 is called the guardian of the genome and how interfering with its function can lead to cancer.

"Thus far, the lineages of wolves that likely gave rise to dogs have not yet been discovered and it's possible that these puppies could be on that lineage, which would be very exciting," said evolutionary biologist Greger Larson, of the University of Oxford, one of the scientists behind a collaborative project aimed at finding out when and where dogs became the first domesticated animals.

The UK's leading cancer charity yesterday welcomed work by British scientists who created a breed of genetically modified hens that can produce cancer-fighting medicines in their eggs. The research could slash the cost of producing drugs and potentially save the NHS millions of pounds.

There are few areas of science more fiercely contested than the issue of what makes us who we are. Are we products of our environments or the embodiment of our genes? Is nature the governing force behind our behaviour or is it nurture? While almost everyone agrees that it's a mixture of both, there has been no end of disagreement about which is the dominant influence.

The research suggests that in mice with Alzheimer's disease certain immune cells that normally protect the brain begin abnormally to consume an important nutrient called arginine. By blocking this process using the drug difluoromethylornithine (DFMO), memory loss and a buildup of sticky proteins known as brain plaques were prevented.

The laboratory-based animal study found a link between greater susceptibility to obesity and diabetes, and whether one's ancestors have been undernourished for several generations, and was published on Friday in the journal Cell Metabolism.

The US Food and Drug Administration has approved a first-of-a-kind drug that uses the herpes virus to infiltrate deadly skin cancer tumours, reducing their size in some cases.

Scientists don't fit a mold - the stories we tell about them shouldn't either. We've created scientist-of-the-month toolkits for teachers, parents/guardians, and informal educators to easily share these stories with their students.

The heavy impact on the environment of meat production was known but the research shows a new scale and scope of damage, particularly for beef. The popular red meat requires 28 times more land to produce than pork or chicken, 11 times more water and results in five times more climate-warming emissions. When compared to staples like potatoes, wheat, and rice, the impact of beef per calorie is even more extreme, requiring 160 times more land and producing 11 times more greenhouse gases.
