A flexible lens controlled by light-activated artificial muscles promises to let soft machines see

Inspired by the human eye, our biomedical engineering lab at Georgia Tech has designed an adaptive lens made of soft, light-responsive, tissuelike materials. Our study is published in the journal Science Robotics.

Adjustable camera systems usually require a set of bulky, moving, solid lenses and a pupil in front of a camera chip to adjust focus and intensity. In contrast, human eyes perform these same functions using soft, flexible tissues in a highly compact form.

Our lens, called the photo-responsive hydrogel soft lens, or PHySL, replaces rigid components with soft polymers acting as artificial muscles. The polymers are composed of a hydrogel —a water-based polymer material. This hydrogel muscle changes the shape of a soft lens to alter the lens’s focal length, a mechanism analogous to the ciliary muscles in the human eye.

AI-guided drones use 3D printing to build structures in hard-to-reach places

Disaster has just struck, roads are inaccessible, and people need shelter now. Rather than wait days for a rescue team, a fleet of AI-guided drones takes flight carrying materials and the ability to build shelters, reinforce infrastructure, and construct bridges to reconnect people with safety.

It sounds like , but new research from Carnegie Mellon University’s College of Engineering combines drones, additive manufacturing, and to rethink the future of aerial construction.

Aerial (AM)—think flying 3D printers, has been fascinating researchers for years, but the natural instability of a drone in flight makes traditional layer-by-layer fabrication nearly impossible. To overcome this, Amir Barati Farimani, associate professor of mechanical engineering, has equipped drones with magnetic blocks to allow for precise pick-and-place assembly and a large language model (LLM) that can translate high-level design goals like “build a bridge” into executable plans.

Rocket maker Firefly Aerospace files to go public under ticker FLY

Rocket maker Firefly Aerospace filed for an initial public offering on Friday, with plans to trade under the ticker symbol “FLY” on the Nasdaq.

Firefly’s planned offering comes during a resurgence period for IPOs after the market collapsed in 2022 as rising interest rates and skyrocketing inflation deterred investors from betting on riskier assets.

Some companies, including Klarna and ticket reseller StubHub, delayed public offerings earlier this year as President Donald Trump’s tariff plans rattled global markets. But venture capitalists are becoming more optimistic after a strong June for deal activity that included a surge in crypto company Circle and a major Meta Platforms deal with Scale AI. Figma also filed its prospectus earlier this month.

Meta launches new anti-scam tools for WhatsApp and Messenger

Meta has announced new tools to help WhatsApp and Messenger users protect themselves from potential scams and secure their accounts.

On Messenger, the company has started testing more advanced scam-detection for suspicious chats that will warn users when a new contact sends a potentially scammy message, giving them the option to send recent messages for AI scam review to check for signs of a scam.

When a potential scam is spotted, users will be alerted and provided a set of suggested actions, such as blocking or reporting the sender.

Microscopic DNA ‘Flowers’ Could Transform Targeted Drug Delivery

Researchers at the University of North Carolina (UNC) have developed microscopic flower-shaped soft robots made from DNA and inorganic materials that can fold, bend, and react to their environment. Detailed in a paper published in Nature Nanotechnology, these microscopic DNA “flowers” are a potential new method for targeted drug delivery and other biomedical applications.

“People would love to have smart capsules that would automatically activate medication when it detects disease and stops when it is healed. In principle, this could be possible with our shapeshifting materials,” said senior author Ronit Freeman, PhD, and associate professor at USC and leader of a research group that is seeking to develop novel designer materials using self-assembling biological components.

The DNA flowers are assembled from hybrid DNA, inorganic crystals that respond to environmental stimuli such as changes in acidity (pH), enabling reversible changes in shape—shrinking, bending, and folding—within seconds. The petals can open or close in response to local environmental conditions, motion that can be used to trigger a chemical reaction, release molecules, or interact with tissues.
