Misadventures at a scientific meeting in Nevada, and ponderings on the idea that physical objects exist only as perceptual phenomena, in our weekly dip into Nature’s archive.

Mercury is shrinking with age — faster than thought

Marine bacteria cooperate to break down complex algal carbohydrates

Marine algae produce sulfated carbohydrates called fucoidans that are chemically too complex for any bacteria to digest alone. Instead, marine bacteria split the task between them in a modular fashion: some strains degrade the molecular backbone, whereas others remove the side branches.

Molecular computation that rolls energetically downhill

A DNA-based computer that operates by relaxing to thermodynamic equilibrium has been demonstrated on ten molecular programs, which completed computations in as little as one minute. Some programs were rerun using distinct inputs up to 25 times and others were scaled up to 100-bit computations — although this slowed them down substantially.

Turning scientific research papers into interactive AI agents

Scientific knowledge is mostly stored in static papers. An automated framework called Paper2Agent can now transform each paper into an active artificial intelligence agent — a virtual corresponding author that answers questions, applies the paper’s methods to new data, and collaborates with other paper agents. This makes research easier to reproduce, reuse and extend.

Tumour cells shape their environment to protect them from the immune system

A subset of pancreatic cancer cells express the genes SERPINE1 or SERPINB2, which form a molecular mesh around them. This sticky matrix helps to retain immunosuppressive cells and exclude the immune cells that kill cancer cells. Disrupting this process in mice improves immune control of pancreatic tumours and sensitizes them to immunotherapy.
