Euclid finds a new comet in images of distant galaxies
C/2026 S1 lies roughly 1.3 billion kilometres from Earth. A recurring trail in the telescope’s images started a sequence of observations and checks.

New possibilities that change what scientists can observe, measure, discover or experimentally test.
Light activates a thirteen-atom copper cluster to transform alcohols and aromatic compounds
Scientists synthesized a tiny copper-hydride cluster that catalyzes selected light-driven oxidations to ketones. The chemistry works on real molecules in the lab, while the hydride arrangement and industrial practicality remain uncertain.

A microscope measured how living cells respond when squeezed
The CFM platform changes how tightly cells are confined while recording images and measuring traction forces. Experiments reveal an initial passive stress response followed by active contraction, not an immediate clinical application.

Engineered mammalian cells can make essential amino acids they normally need supplied
A genetic engineering method screened millions of combinations and enabled cultured cells to grow without added valine or isoleucine. This is a synthetic-biology demonstration, not a patient-tested therapy.

An AI workflow checked 4,452 economics papers and flagged differences in 3,460
An NBER working paper reports an LLM workflow that reruns published calculations and proposes further tests at scale. Flags do not automatically mean the scientific findings are wrong.

Living cells can turn a fleeting RNA signal into a DNA trace that remains readable
Detectron sensors recognize selected RNA sequences and convert them into DNA barcodes. In bacteria, they recorded phage infections that could be read later by sequencing.

A flash of light mapped proteins on both sides of cell membranes in the living brain
The tmPhoxID method uses a light-triggered reaction that crosses the cell membrane. In mice it reconstructed protein neighbourhoods around several receptors without studying inside and outside separately.

Why some “zombie” cells linger with age: mice reveal a failure in immune cleanup
A peer-reviewed study links decline of a cellular recycling pathway to failed senescent-cell clearance; restoring it reduced cell burden and fibrosis in mouse models, not in patients.

Nanoparticles designed for longer RNA delivered gene editors to three mouse organs
LC-1 was selected using an mRNA as large as those needed for gene editors. In mice it improved editing in liver, brain and lung; this is not yet a human therapy.

A radio signal has been localized directly to an exoplanet for the first time
MeerKAT traced radio bursts to β Pictoris b, separating them from the host star. The preprint interprets them as aurorae and infers at least a 1.25 kG field at the emission site.
