Pictures of Living Things

By Maxwell Coyle

So much of science and medicine comes down to taking pictures. Biology, especially, has long been considered an observational enterprise.

The Most Lethal Part of Cancer

By Lauren Shields

The most lethal part of cancer is that it spreads.

Stopping the spread of cancer, known as metastasis, would be a leap forward in treatment. However, first, we must better understand why and how metastasis happens.

The Science of Dietary Risks

By Hanna Starobinets

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.

Unraveling Metastasis, the Lethal Agent of Cancer

By Maxwell Coyle

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.

Biologically-Inspired Engineering

By Hanna Starobinets
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.

mtDNA Recombination: O'Farrell Lab

By Lauren Shields

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.

This month in DNA repair: the elephant and the prize

By Hanna Starobinets
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.

The Parts of the Brain

By Maxwell Coyle
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: A Neurodegenerative Disease

By Lauren Shields

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.

Up and Down: Mars and DNA

By Hanna Starobinets
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.
