Is Saliva the Next Frontier in Cancer Detection?
In the late 1950s, dentist and U.S. Navy Captain Kirk C. Hoerman, then a young man in his 30s, attempted to answer a bold question: Might the saliva of prostate cancer patients have different characteristics from that of healthy people? Could it contain traces of a disease that’s so far away from the mouth?

The Cause of Depression Is Probably Not What You Think
People often think they know what causes chronic depression. Surveys indicate that more than 80% of the public blames a “chemical imbalance” in the brain. That idea is widespread in pop psychology and cited in research papers and medical textbooks. Listening to Prozac, a book that describes the life-changing value of treating depression with medications that aim to correct this imbalance, spent months on the New York Times bestseller list.

People don't mate randomly – but the flawed assumption that they do is an essential part of many studies linking genes to diseases and traits
People don’t randomly select who they have children with. And that means an underlying assumption in research that tries to link particular genes to certain diseases or traits is wrong.

The Viruses That Fight Disease - Weizmann Wonder Wander
The myriads of microbes in our gut, collectively termed the microbiome, are considered important to our health, but they can also harbor bacteria that contribute to inflammatory bowel disease or other disorders. Currently, however, it is impossible to target such disease-contributing bacteria without harming the surrounding beneficial microbes.

Huge plan to map the DNA of all life in British Isles
Seventy thousand species. That’s the best guess for the tally of life, including plants, animals and fungi, found in Britain and Ireland. And it’s the target of one of biology's most ambitious projects - scientists want to map the DNA of every single one of these organisms.

New CRISPR-based map ties every human gene to its function
A new CRISPR-based map ties every human gene to its function using a tool called Perturb-seq. The work was led by Jonathan Weissman and colleagues at MIT and the Whitehead Institute, and is free for other scientists to use.

How 'frozen zoos' could save vanishing animals from extinction
When Kurt Benirschke started collecting skin samples from rare and endangered animals in 1972, he didn't have a firm plan on what to do with them. As a researcher at the University of California San Diego, he believed that one day the tools would be developed to use them to save those animals. A few years later, he moved his collection to San Diego Zoo, and called it the Frozen Zoo.

Thousands of intestinal viruses have now been mapped. And they can be used to fight antibiotic resistance
A new method developed at the University of Copenhagen has been used to identify more than 1,000 bactericidal viruses in the human intestines. The researchers believe the discovery may help fight antibiotic resistance.
