4

All-optical chip LightGen and Chinese photonic AI advances

Researchers presented LightGen, an all-optical chip with two million photonic ‘neurons’ claiming much higher speed and energy efficiency than electronic chips, signaling major progress in photonic AI hardwareSource 1.

5

Tiny autonomous robots demonstrate programmable microrobotics

Teams at University of Pennsylvania and University of Michigan reported the world’s smallest fully programmable autonomous robots (≈200×300×50 ”m), opening paths for microscale manufacturing and medical applicationsSource 1.

6

First full chemical synthesis of verticillin A completed

MIT chemists reported the first complete synthesis of verticillin A, a fungal natural product long seen as a promising anticancer agent, enabling deeper study and drug development effortsSource 1.

7

CRISPR gene therapy shows large LDL and triglyceride reductions in humans

A Phase 1 first-in-human CRISPR therapy targeting ANGPTL3 was reported safe and able to reduce LDL cholesterol by nearly 50% and triglycerides by 55%, indicating potential for durable lipid-lowering treatmentsSource 1.

8

Antimatter production boosted at CERN’s ALPHA experiment

CERN’s ALPHA group reported an eightfold increase in antimatter production by sympathetically cooling positrons with laser-cooled beryllium ions, enabling creation of >15,000 antihydrogen atoms in under seven hoursSource 1.

9

Tryptophan confirmed on asteroid Bennu from OSIRIS‑REx samples

Analysis of OSIRIS‑REx samples from Bennu confirmed presence of tryptophan, an amino acid used in protein biosynthesis, supporting theories that asteroids delivered prebiotic material to early EarthSource 1.

10

Global glacier timeline and 'Peak Glacier Extinction' concept released

An international team produced the first global timeline for glacier disappearance and introduced ‘Peak Glacier Extinction,’ projecting dramatic glacier losses (e.g., most Alpine glaciers gone under current warming trends) and highlighting urgent climate impactsSource 1.

11

Virus-view dual confocal and AFM (ViViD‑AFM) microscopy reveals influenza entry

ETH Zurich researchers demonstrated ViViD‑AFM—combining atomic force microscopy with fluorescence imaging—to visualize influenza virus invasion of human cells at unprecedented resolution, improving understanding of infection mechanismsSource 1.

12

Small photonic AI chip on optical-fibre tip decodes images at light speed

Researchers reported an AI chip smaller than a grain of salt that mounts on an optical-fibre tip using a diffractive neural network to decode images at optical speeds with very low energy, promising compact, energy‑efficient imaging and sensingSource 1.

13

New blood test detects early-stage pancreatic cancer with high accuracy

Oregon Health & Science University researchers developed a blood test able to detect early-stage pancreatic cancer with reported ~85% accuracy, potentially enabling earlier intervention for a typically late-detected cancerSource 1.

14

mRNA delivery into HIV‑hiding white blood cells demonstrated

Researchers reported the first delivery of mRNA into white blood cells that hide HIV using specially formulated nanoparticles (LNP X), instructing those cells to reveal hidden virus and offering a path to eradicate reservoirsSource 1.

15

AI systems’ environmental footprint assessed as comparable to major cities

A new study suggested AI systems may have a carbon footprint equivalent to that of New York City (2025) and a water footprint comparable to global bottled water consumption, raising sustainability concerns for large-scale AI deploymentsSource 1.
