Slime-like artificial muscle reshapes on command, heals after damage and turns one robot into many

Breaking away from conventional robots that perform only predefined functions once fabricated, researchers have developed a next-generation artificial muscle that can change its shape in real time, recover from damage, and even be reused. The study is published in Science Advances.

The researchers developed a new type of dielectric elastomer actuator (DEA) using a phase-transitional ferrofluid (PTF) that behaves as a solid at room temperature but becomes fluid-like and highly flexible when exposed to external stimuli such as heat or magnetic fields.

Dielectric elastomer actuators (DEAs) are soft transducers that convert electrical energy into mechanical motion and are often referred to as artificial muscles because of their ability to move rapidly and precisely like human muscles.

Ocean bottom seismometers could improve earthquake warning times in Pacific Northwest

If there is a magnitude 8 or 9 megathrust earthquake off the coast of the Pacific Northwest, data from ocean bottom seismometers (OBS) could improve earthquake detection times calculated by the ShakeAlert system.

At the 2026 SSA Annual Meeting, Zoe Krauss said ShakeAlert’s earthquake detection time could be improved by 5 to 9 seconds by incorporating data from six cabled OBS deployed offshore Oregon as part of the Ocean Observatories Initiative (OOI) Regional Cabled Network and five cabled OBSs deployed offshore Vancouver Island on Ocean Networks Canada’s (ONC) NEPTUNE cable.

There are currently only two cabled OBSs offshore Oregon, but the Cascadia Offshore Subduction Zone Observatory (COSZO) project will add four new OBS to the OOI network this summer, bringing these potential added detection times closer to reality.

Google Blocks 8.3B Policy-Violating Ads in 2025, Launches Android 17 Privacy Overhaul

Google this week announced a new set of Play policy updates to strengthen user privacy and protect businesses against fraud, even as it revealed it blocked or removed over 8.3 billion ads globally and suspended 24.9 million accounts in 2025.

The new policy updates relate to contact and location permissions in Android, allowing third-party apps to access the contact lists and a user’s location in a more privacy-friendly manner. This includes a new Contact Picker, which offers a standardized, secure, and searchable interface for contact selection.

“This feature allows users to grant apps access only to the specific contacts they choose, aligning with Android’s commitment to data transparency and minimized permission footprints,” Google said.

New Hydrogel Helps Bone Grow Without Transplant or Implants

A new hydrogel may offer a way to regenerate bone—without transplants or implants.

Early research shows the material can support bone growth by creating a scaffold that encourages the body’s own repair processes. It’s designed to integrate with tissue and break down as new bone forms.

While still in early stages, the approach could represent a shift toward less invasive, regenerative options for bone repair.

Researchers have developed a soft laser-printed scaffold made almost entirely of water that bone cells readily colonize.

Reddit Analysis Uncovers Unreported GLP-1 Side Effects

A large-scale analysis of Reddit data identifies symptoms—including fatigue and menstrual changes—frequently missed in clinical trials. These real-world patient insights highlight a broader spectrum of physiological responses to semaglutide and tirzepatide. More on the analysis.

Reproductive symptoms, temperature-related complaints, and psychiatric symptoms were among the side effects of GLP-1 drugs reported in an analysis of Reddit posts.

“Clinical trials tell us a lot, but they’re conducted under very controlled conditions with carefully selected participants,” Neil Sehgal, a doctoral student at the University of Pennsylvania School of Engineering and Applied Science, Philadelphia, told Medscape Medical News. “At the same time, millions of patients are using Reddit every day and sharing very detailed accounts of their experiences with these medications.”

To investigate signals that the medical community “might be missing or underappreciating,” Sehgal and colleagues developed an AI-based system to automatically extract and categorize symptoms from Reddit posts at scale.
