Blue Eye Pulsar, AI CRISPR, and Hawking Recoil Lead Today's Science Breakthroughs

Astronomers solved a 50-year-old mystery by detecting the first radio pulses from a compact central object, nicknamed the 'Blue Eye Pulsar'. AI-designed synthetic 'molecular scissors' outperformed natural CRISPR proteins in human cells, while a tabletop experiment observed the long-sought recoil from Hawking radiation for the first time. In medicine, an Australian CAR T-cell therapy showed a 100% cure rate for solid tumors in preclinical models. China successfully launched and recovered its first orbital reusable rocket using an innovative net system, and a fusion startup directly extracted electricity from plasma.

First radio pulses from a 'silent' dead star solve 50-year mystery Using the highly sensitive MeerKAT radio telescope, Chinese astronomers detected faint radio pulses from the central compact object 1E 1207.4−5209, nicknamed the 'Blue Eye Pulsar'. Published in Nature Astronomy, the discovery proves these enigmatic neutron stars are not truly radio-silent but simply too faint for previous technology, directly linking them to ordinary radio pulsars and offering fresh insights into stellar evolution. 1

AI-designed synthetic CRISPR scissors outperform natural gene-editing proteins Researchers used Meta's ESM Inverse Folding model to create SynTnpB nucleases, synthetic gene editors with as little as 72% sequence identity to natural counterparts. Reported in Science, these AI-designed tools achieved up to 50% editing efficiency in human cells, nearly four times better than the natural enzyme, establishing a new class of CRISPR-compatible molecular tools. 2

Optical fiber experiment observes Hawking radiation and its source recoil An international team created an artificial event horizon inside a photonic crystal fiber, measuring both Hawking-like radiation and the long-predicted back-reaction on the source pulse. The study in Nature provides a powerful tabletop method to explore the intersection of quantum physics and general relativity where real black hole observations are impossible. 3

Australian precision CAR T-cell therapy cures 100% of solid tumours in lab Researchers at Melbourne's Peter MacCallum Cancer Centre engineered T-cells with an extra 'armour' gene that releases inflammatory proteins directly inside the tumour. Supported by a $17.7 million government grant, the therapy eradicated breast, colon, and ovarian cancer models in mice with no toxic side-effects, paving the way for human clinical trials. 4

China launches and catches first orbital reusable rocket with sea-net The Long March 10B rocket successfully flew and was recovered by a 'well'-shaped flexible net on a sea platform, a global first that bypasses the heavy landing legs used by SpaceX. This milestone breaks the US monopoly on commercial reusable rocket technology, reshaping the global launch market and accelerating China's low-Earth orbit satellite deployment. 5

Fusion startup Realta directly extracts electricity from plasma in landmark test Realta Fusion installed an electrostatic direct energy converter on the WHAM magnetic mirror device at the University of Wisconsin–Madison, harvesting hundreds of watts of power from charged plasma particles to light a bulb. The proof-of-concept, a first for a private fusion company, demonstrates a potentially more efficient path to fusion power by bypassing the standard thermal conversion cycle. 6
