Castration extends male life span across many mammalian species, including humans, and neutering older male mice adds over 30% to lifespan. The preprint reports the effect occurs even when the procedure is done later in life.
Key points
Removing the testicles extends male life span across many mammalian species, including humans.
Neutering older male mice lengthens their lives by more than 30%.

Imaging exoplanets below the telescope stability limit – 2–15× sensitivity gain
Imaging exoplanets below the telescope stability limit introduces a physics-based starlight subtraction method that achieves 2–15 times better sensitivity than standard techniques. The approach uses automatic differentiation to optimize millions of model parameters on JWST NIRCam coronagraph data and enables the first detection of 51 Eridani b at 4.3 µm.
Key points
Sensitivity 2–15 times superior to standard techniques.
First detection of 51 Eridani b at 4.3 µm.
Automatic differentiation optimizes millions of model parameters.

MayoClinic study finds crafting cuts risk 42% of mild cognitive impairment
MayoClinic study reports adults 70+ who did crafts in late life had a 42% lower risk of mild cognitive impairment. A large survey found a strong association between frequent knitting and feeling “calm and happy.”
Key points
42% lower risk of mild cognitive impairment for adults 70+ who did crafts.
Survey shows frequent knitting strongly linked to feeling calm and happy.

NeuroCellPress paper finds hippocampal neurons use distinct codes
NeuroCellPress paper reports hippocampal neurons use related but distinct neural codes to represent self, others, and gaze. The structure may help the brain distinguish perspectives and generalize across them.
Key points
Hippocampal neurons use related, but distinct, neural codes for self, others, and gaze.
This structure may help the brain both distinguish perspectives and generalize across them.
