Ernst Haeckel’s Pedigree of Man, 1874

After completing his studies in medicine and biology, a restless Ernst Haeckel set off for Italy in 1859 to study art and marine biology. The diversity of life fascinated the 26-year-old Prussian, and in addition to painting landscapes, he spent the

Cell-In-Cell Action

The mechanism by which tumor cells end up harboring other living cells remains elusive, and the sparse evidence acquired thus far has led researchers to propose different hypotheses. 

Helpful Bacterial Metabolites

While gut microbiota appear to have both positive and negative impacts on our  health, in the guts of healthy, lean individuals, the good outweighs the bad.  

Harmful Bacterial Metabolites

Gut bacteria that feed on healthy food appear to amplify the nutritional benefits of those foods. However, they also appear to amplify the undesirable effects of unhealthy food.

From the Ground Up

As the planet warms plant growth will likely increase—locking up some of that extra carbon dioxide by converting it into vegetative biomass—but that’s not the whole story.

Powering Clinical Trials

To ensure high-quality clinical trials of a malaria vaccine, organizers in rural Africa must first upgrade electrical and research infrastructures.

Personalized Athletics

Motivated by a career-ending ligament tear, a former NFL player starts a company to test athletes' genetic predispositions to common sports injuries.

An Unlichenly Pair

A young botanist pays tribute to his mentor by naming a newly discovered, rare species in his honor.

String Theory

New types of biological filaments are turning up in yeast, fly, bacterial cells and in rat neurons, and they may yield clues to how the cytoskeleton evolved from metabolically active enzymes.

Profile

3-D Seer

Dissatisfied with the uncertainty of crystallography, Ned Seeman invented a new way of assembling the molecules that encompass the logic of life.

Reading Frames

Faculty Fallout

Administrators have taken over US universities, and they’re steering institutions of higher learning away from the goal of serving as beacons of knowledge.

Battling Malaria in Africa

When general practitioner John Lusingu returned to his native Tanzania to do research on malaria, he was met with a total lack of science infrastructure. 

Haeckel’s Radiolarians

After completing his studies in medicine and biology, Prussian naturalist Ernst Haeckel set off for Italy in 1859, where, in addition to painting landscapes, he spent the climactic months of his stay glued to his microscope observing and sketching.
