Closing in on the causes of chronic neuropathic pain

Wed, 18 Mar 2026 00:00:00 +0000

Replacing the immune system of the brain

Wed, 11 Mar 2026 00:00:00 +0000

A new method enables engineered immune progenitor cells to replace microglia in mice and reveals how a genetic mutation can lead to inflammation in the brain.

Ancient photoreceptor shapes behavioural responses

Wed, 04 Mar 2026 00:00:00 +0000

Experiments on Drosophila show that an evolutionarily conserved photoreceptor that senses light outside of the retina can regulate responses to direct visual cues.

A sense of direction

Mon, 02 Mar 2026 00:00:00 +0000

Migratory moths use both magnetic and visual cues for navigation when travelling long distances in the dark.

Scaling up efforts to target evolving viruses

The discovery of the mammalian fusome

Wed, 18 Feb 2026 00:00:00 +0000

The presence of an organelle called the fusome in species as diverse as Drosophila and mammals indicates an ancient, conserved programme of germ cell development.

Synaptic footprints of time in working memory

Mon, 16 Feb 2026 00:00:00 +0000

Temporary changes in synapses may allow working memory to keep track of both events and their timing.

Redefining borders in the sensorimotor cortex

Mon, 09 Feb 2026 00:00:00 +0000

Experiments mapping individual neurons in the sensorimotor cortex of mice show that sharp transitions in functional properties can define cortical regions.

Lipids challenge ligands to control receptors

Wed, 04 Feb 2026 00:00:00 +0000

MRI sets its sights on collagen

Mon, 02 Feb 2026 00:00:00 +0000

Reducing the echo time of a whole-body MRI scanner makes it possible to image collagen, an important structural protein found in bones and tendons.

The cellular logic of limb regeneration

Thu, 22 Jan 2026 00:00:00 +0000

Hierarchical communication between cells with distinct positional memories orchestrates the regeneration of missing limb structures in axolotls.

Linking neuron-glia interactions and longevity

Mon, 19 Jan 2026 00:00:00 +0000

Proteomics experiments on Drosophila reveal sex-specific effects in aging, and an important role for a protein called DIP-β.

Finding a role for non-coding DNA in trypanosomes

Tue, 13 Jan 2026 00:00:00 +0000

Non-coding DNA is essential for both humans and trypanosomes, despite the large evolutionary divergence between these two species.

Lipid balance and chemoresistance in cancer cells

Mon, 12 Jan 2026 00:00:00 +0000

A shift in the balance between two lipids – cholesterol and sphingomyelin – makes hybrid epithelial-mesenchymal cancer cells less responsive to certain chemotherapy drugs.

Probing the proteome

Wed, 07 Jan 2026 00:00:00 +0000

Raman spectroscopy can be used to predict cellular physiology and proteome composition in E. coli.

Identifying new targets in the fight against opioids

Mon, 05 Jan 2026 00:00:00 +0000

Experiments reveal that a time-dependent epistatic interaction influences how mice respond to opioids, and that intracellular fibroblast growth factors also influence opioid sensitivity.

Slowing the growth of drug-resistant tumors

Thu, 18 Dec 2025 00:00:00 +0000

Using drugs that inhibit enzymes called CDK4/6 and CDK2 extends the G1 phase of the cell cycle and helps to slow the growth of drug-resistant breast cancer.

The little brain supervises learning in the big brain

Thu, 11 Dec 2025 00:00:00 +0000
