Using MRI, engineers have f=
ound a way to detect light deep in the brain (6 minute read)
Scientists often label cells with prote=
ins that glow to measure changes in gene expression, but this technique is =
difficult to apply to structures deep within the brain as light scatters to=
o much before it can be detected. MIT engineers have engineered blood vesse=
ls to express a protein that causes them to dilate in the presence of light=
.. This dilation can be observed with magnetic resonance imaging, allowing r=
esearchers to pinpoint the source of light. The new technique allows resear=
chers to explore the inner workings of the brain in more detail than previo=
usly possible.

/strong>
pg_lakehouse is an extension that trans=
forms Postgres into an analytical query engine over object stores. Querying=
non-operational data by moving it into a cloud data warehouse or operating=
a new query engine is expensive and time-consuming. pg_lakehouse allows th=
is data to be queried directly from Postgres, eliminating the need for new =
infrastructure, loss of data freshness, data movement, and non-Postgres dia=
lects of other query engines.

The Alternative Implementat=
ion Problem (8 minute read)
Positioning a project as an alternative=
implementation of something is a losing proposition. Building an alternati=
ve implementation means reacting to the whims of the canonical implementati=
on - they have control over the direction of the project and you can only k=
eep up. It's better in most cases to make an original system rather than be=
ing chained by expectations to match another implementation.
