Red wine. Coffee. Dark chocolate. Epidemiologists, doctors, and nutrition scientists are constantly analyzing the good and bad consequences of different food and beverage components of our diets and reporting correlative data.

Cancer is not just one disease. Were it, we could imagine a single cure. Instead, we find that cancer is a mix of clinically separable diseases.

The past few years have seen an increase in robotics inspired by the natural world. These robots are designed to look and move like animals, from flying like a bird to running and jumping like a cheetah. Aside from being intriguing engineering challenges, these types of robotics could also be used as a substitute for humans in dangerous or difficult situations.

Mitochondria are the powerhouses of the cell. These organelles support cellular functions through ATP production and have been implicated in diseases ranging from cancer to Parkinson’s. Additionally, their function extends beyond energy.

Increases in body size and lifespan should theoretically make an animal more prone to DNA replication errors that can produce cancer-causing mutations. African elephants, weighing up to 12,000 pounds and living up to 70 years, should be riddled with tumors, yet somehow they live long, cancer-free lives.

Consider brains and computers. How are they similar? Both can perform complex, rational tasks. Both take inputs and make decisions. More generally, both occupy physical space, although computers increasingly less so. As part of their physical nature, both can be subdivided into parts, the organization and connectivity of which creates their function.

Tauopathies are a spectrum of neurodegenerative diseases defined by their cellular pathology. Their name refers to the protein tau which aggregates pathologically in clumps known as fibrils.

Water on Mars! And this time, it’s liquid! Salty water flows on Mars slopes – during “warm seasons” of above 10 degrees Fahrenheit – producing streaks of hydrated minerals that NASA spotted from their Mars Reconnaissance Orbiter. The findings were announced in a news conference on Monday, September 28, and published the same day in Nature Geoscience by Lujendra Ojha et al.
In 2015, evolution is considered an older discovery, and perhaps seems dusty to a generation piqued by CRISPR gene editing, pluripotent stem cells, and the still opaque mysteries of the microbiome.
The breast, or mammary gland, is a unique organ: it’s the only one that develops predominantly after birth – during puberty – in an organism with a fully-developed immune system. Early development trains the immune system to distinguish between “self” and “non-self” in an effort to prepare for all sorts of infectious attacks throughout life.
