KAIST team develops power-free eyedrop patch; space use remains unverified

KAIST and Seoul National University Bundang Hospital researchers developed a wearable eyedrop patch. Pressing it triggers a chemical reaction that produces carbon dioxide to propel medication, without electricity or an external pump. Ground experiments showed relatively stable delivery, and human tests found results similar to conventional eyedrops. Testing in space or simulated microgravity has not yet taken place.

What to know

  • 01

    The thumbnail-sized patch is made mainly from a flexible biocompatible polymer and is worn beside the eye.

  • 02

    Three chambers linked by microchannels hold pre-moistened fabric, a foaming mixture of vitamin C and baking soda, and about 20 microliters of eyedrops.

Why it matters

The research addresses astronauts’ need to self-administer eyedrops, but the patch’s suitability for space use still requires further testing.

His conversation drew Interpol’s attention. He was charged with using a communications service to harass, intimidate or offend and will undergo a mental health assessment. How Interpol obtained the chats, and whether Anthropic proactively supplied them, remains unclear.

Amazon’s Jassy says broader enterprise AI adoption needs inference costs cut to a tenth

Amazon CEO Andy Jassy says AI inference costs must fall to roughly one-tenth of current levels for broad adoption in enterprise software. He described everyday business software as an underdeveloped market, with costs limiting adoption. Amazon hopes its Trainium chips can provide a lower-cost alternative, and Jassy said its chip business is helping reduce inference expenses.
