This issue’s insight: If AI Can Solve It, What Do You Sell? →

Topic states at issuance

Memory resilience

Compare sleep, representational drift and selective synaptic perturbation to investigate changes compatible with memory.

Next evidence
Matched perturbations with different targets, fixed versus adaptive readout, and retention with or without relearning.
See the current topic separately ↗

Shield: screening adoption

Guardant announced Shield’s inclusion in EviCore guidelines, effective January 1, 2027. This is not an update to detection performance.

Next evidence
Track implementation, tests and payments, participation by previously unscreened people, and completed follow-up colonoscopies separately.

Therapy & companion diagnostics

Linked approval; uptake and payment open

Next evidence
Confirmatory evidence, payer policies covering the new use, and clinical adoption.

Compute for science

A collaboration route exists from Japan. Check funding, compute allocation, disclosure and IP conditions.

Next evidence
Check eligibility, collaborators, compute allocations, publication and IP terms. Deadline: December 1 at noon ET; decisions scheduled for March 1, 2027.

AI–scientist collaboration

Institutional report; independent verification open

Next evidence
Independent replication, public evaluation methods, and records of successes and failures from hypothesis to experiment.

What Scientific AI Companies Sell Next: Experimental Data, Labs, and Drug Discovery Assets

Ginkgo announced experimental-services and in-house laboratory partnerships. Schrödinger contributed two drug programs to Tectora.

Next evidence
Repeat orders, laboratory operation and recurring revenue, asset rights and development costs.

Who Will Build the Systems to Oversee Clinical AI?

ARPA-H announced ADVOCATE development plans covering patient-facing AI, supervision, implementation and independent evaluation.

Next evidence
Missed errors, false alarms, appropriate clinical handoffs and evaluation in routine care.
See the current topic separately ↗

How Far Can Human Neural Tissue Compensate for Lost Function?

A study examined human cortical organoid growth, connections, activity and behavior in mice with major developmental depletion of cortical and hippocampal excitatory neurons.

Next evidence
Manipulate graft activity during specific tasks to distinguish modulation of host circuits from information processing.

Can measuring brain function help us choose an antidepressant?

In SMART-D’s main analysis of 47 participants over eight weeks, selecting a marker-consistent drug did not demonstrate better outcomes.

Next evidence
Drug comparisons at the same treatment stage, and separate validation of early changes to inform subsequent decisions.

What Do New Cells Contribute to a Brain That Preserves Memories?

A human postmortem study suggested stalled neurogenesis associated with depression. A separate mouse study found that greater survival of new neurons improved discrimination of similar contexts.

Next evidence
Relate cell stage and circuit integration to memory retention, context discrimination and relearning.
