Ancient DNA supports Gothic origin story from Scandinavia

New Capabilities

Co-led the Nature study with Leiden and Gothenburg

In 551 C.E., a Gothic historian named Jordanes wrote that his people sailed from a frozen island called Scandza and swept south to the Black Sea. More than 4,700 ancient genomes now show a large migration from Scandinavia into northern Poland around the time Gothic artifacts first appear there.

Bacterial antiviral enzyme builds DNA repeats like telomerase

New Capabilities

Contributed phylogenetic analyses to the DRT10 study

Bacteria fight viruses with an enzyme that writes repetitive DNA from an RNA template. The system, called DRT10, works much like telomerase, the enzyme that protects chromosome ends in humans and most other eukaryotes.

Needle-thin brain implant packs recording, stimulation, and drug delivery into one fiber

New Capabilities

As of September 2026: Collaborating institution

The microfluidic Axialtrode (mAxialtrode) is thinner than a sewing needle. Through a single soft fiber, it can record neural signals, inject drugs, and stimulate brain tissue with light at multiple depths at once.

New proof of four-color theorem runs in near-linear time

New Capabilities

As of September 2026: Host institution for Mikkel Thorup

The four-color theorem says any map can be colored with four colors so no neighboring regions match. A team of six mathematicians posted a new proof in March 2026 that colors any planar graph in near-linear time, down from quadratic in the previous accepted proof.
