Medical research

This miniature drug factory fits on a few lab benches

Automated system takes only 80 hours to turn out hundreds of doses of a medical product made by living organisms.

An all-in-one bench-top system can churn out hundreds or thousands of doses of a medically useful protein in a few days — and can easily switch to manufacturing other proteins.

Biologic drugs, or biologics, are medical products such as vaccines that are produced by living organisms. Biologics could potentially serve as personalized treatments, but today’s large-scale drug production facilities cannot efficiently manufacture personalized biologics.

To address this, Christopher Love at the Massachusetts Institute of Technology in Cambridge and his colleagues designed a compact, automated system that, unlike other designs, links all the steps of biologic assembly. In the new system, yeast rapidly produces a protein in bulk. A purification system then separates the molecule from its biological source without chemically altering the protein. Finally, the protein is combined with other ingredients into the final product.

The researchers produced medically functional amounts of three protein biologics, including human growth hormone for treatment of growth deficiencies. The system can also be expanded to make biologics, such as insulin, that are more difficult to manufacture than those the system has already made.

Climate change

Antarctic rocks on the rebound could raise sea level much more than expected

When the ice covering the west of the continent disappears, the bedrock could rise up and shove extra water into the ocean.

Forests that float in the clouds are drifting away

Tropical cloud forests are safe havens for a vast range of creatures and plants, but they are under siege around the globe.

Dim stars that have failed at fusion are masters of spin

Three brown dwarfs whirl on their axes at a dizzying rate that might be close to the celestial speed limit for these bodies.

Meat lovers worldwide pay climate little heed

People are eating more poultry and fish — but they’re not giving up their hamburgers.

A century of US data documents obesity’s racially skewed rise

An analysis also finds that obesity is common at a much younger age among people born in the early 1980s than those born in the late 1950s.
