Robotic artificial muscles based on novel material combinations reduce energy consumption: Study

California [US], November 10 (ANI): Actuators, which transform electrical energy into motion or force, serve an important role in everyday life that is often overlooked.

Soft material-based actuators, in particular, have gotten a lot of attention in the scientific community in recent years because of their lightweight, quiet operation, and biodegradability.

A simple method for developing soft actuators is to use multi-material structures, such as “pockets” formed of flexible plastic films filled with oils and covered with conductive plastics. When electrically activated, the film displaces the fluid and contracts the pocket, much like a biological muscle.

This technique can be used to create robot muscles, changeable optics, and tactile surfaces. However, until today, continual electrical stimulation only allowed for short-term muscular contractions, posing a considerable practical barrier.

The study was published research in Nature Electronics.

Researcher Ion-Dan Sirbu from Scuola Superiore Sant’Anna, formerly a doctoral student at the University of Trento under the supervision of Giacomo Moretti and Marco Fontana, began investigating this phenomenon during a research period at Johannes Kepler University in Linz.

Together with the Austrian research group, Ion-Dan Sirbu developed a system that enables accurate force measurement in these actuators.

“During my research on common material combinations,” Ion-Dan Sirbu explained, “I also experimented with a plastic film that a fellow doctoral student, David Preninger, used for his work on biodegradable artificial muscles. As soon as we noticed that this material can sustain a constant force for arbitrarily long periods, we realized we had made a significant discovery.”Since then, the team has worked on a theoretical model and conducted in-depth material characterizations. It became apparent that the key experimental results could be accurately described using simple models.

“The beauty of our model is its simplicity and that it is not limited to existing actuators. We believe our results will provide the scientific community with a simple yet powerful tool for designing and investigating new systems,” said David Preninger, co-first author of the paper and PhD-student at the Soft Matter Physics department at Johannes Kepler University.

“What’s interesting is that not only have we made this technology more functional, but our study enables the identification of material combinations that bring up to thousandfold energy consumption reductions” adds Prof Kaltenbrunner.

Utilizing the identified material combinations, scientists have successfully developed and operated various types of artificial muscles, variable gradient optics, and tactile displays.

Prof Fontana emphasized, “Understanding the fundamental mechanisms underlying soft actuators as established by this study has the potential to make a significant leap in the field of assistive devices, automatic machines, and mobile robots for terrestrial, marine, and space exploration. All these sectors are in search of low-cost, high-performance solutions, which shall also be capable of ensuring low consumption and environmental impacts for sustainability.” (ANI)

Veteran actress, politician and beloved superstar Nora Aunor has passed away at the age of 71.

Her son, Ian De Leon, confirmed the sad news in a Facebook post on Tuesday, 16 April 2025. Sharing a photo of his late mother, he wrote:

“With deep sorrow and heavy hearts, we share the passing of our beloved mother, Nora C. Villamayor ‘Nora Aunor’ who left us today at the age of 71. She was the heart of our family,  a source of unconditional love, strength, and warmth. Her kindness, wisdom, and beautiful spirit touched everyone who knew her. She will be missed beyond words and remembered forever.”

The late star’s wake will be held at The Chapels, Heritage Park in Taguig, according to her daughter and fellow actress Lotlot de Leon.

A National Treasure

In 2022, Nora Aunor was officially recognised as a National Artist for Film and Broadcast Arts by the Philippine government, the highest honour given to individuals who have made a lasting impact on the country’s arts and culture. She was honoured alongside screenwriter Ricky Lee and the late director Marilou Diaz-Abaya.

Cause of Death

Neither the 71-year-old’s family nor authorities have confirmed a cause of death yet. However, according to the media outlet Inquirer.com, she was at a Pasig hospital for an undisclosed procedure.

Career Highlights

Nora Aunor rose to fame as a singer and actress, later becoming one of the most respected names in Philippine cinema. She is best known for her award-winning performance in the critically acclaimed film Himala.

Her most recent film appearance was in Mananambal, alongside actress Bianca Umali. On television, her final role was in the GMA Afternoon Prime series Lilet Matias: Attorney-at-Law.

A true icon, Nora Aunor leaves behind a rich legacy and a nation in mourning.

Tributes Pour In

“Every tear she shed onscreen felt like a collective heartbreak. Every line she delivered became etched in the memory of Philippine cinema… Nora, salamat sa sining. Salamat sa puso,” wrote Charo Santos-Concio said in her post.

“Despite her legendary status, she carried herself with such modesty — confident in her craft, yet never boastful,” Actress Lovi Poe said in her post.

“The FDCP mourns the passing of National Artist Nora Aunor — an icon, a legend, and a voice that captured the soul of a nation. Her performances were never just roles; they were reflections of truth, hope, and resilience,’ wrote The national film council of the Philippines.

“We extend our deepest condolences to the family, friends, fans, and every Filipino soul mourning the loss of our beloved Superstar and National Artist,” said noted social activist Persida Rueda-Acosta.

OSCAR SHOCKS AND SURPRISES: WHO IS LIKELY TO WIN BIG ON HOLLYWOOD’S BIGGEST NIGHT

Published

on

On the big screen, Deadpool clashed with Wolverine in a spectacle that set social media abuzz, while animated darling Inside Out 2 stormed the box office — leaving Joker’s sequel in its shadow. Off-camera, there was more drama as Blake Lively and Justin Baldoni found themselves locked in a bitter legal feud.

The off-screen action, however, didn’t stop there. There were debates over The Brutalist’s daring use of AI and Anora’s controversial decision to forgo an intimacy coordinator sparked plenty of heated exchanges on social media.

As the Academy Awards draw near on Sunday, March 2,  2025, the anticipation is palpable. We look at some of the possible winners on Hollywood’s biggest night.

Best Picture: Anora leads, but there others 

Anora is just barely ahead—but only by a hair. Why? A string of major wins, including the Critics Choice, Producers Guild, and Directors Guild Awards, put it in prime position. But rivals like Conclave and The Brutalist are lurking. We could see a historic upset here.

Best Director: Close fight between Sean Baker and Brady Corbet

Two directors, one golden statuette. Sean Baker (Anora) and Brady Corbet (The Brutalist) are neck and neck. But history favours Baker, thanks to the Directors Guild Awards’ near-flawless Oscar track record. Still, nothing is certain.

Best Actor: Both Adrien Brody and Timothée Chalamet are in the race

Adrien Brody (The Brutalist) was cruising toward his second Oscar—until Timothée Chalamet (A Complete Unknown) crashed the party with a major SAG win! Brody is still the favourite, but don’t be shocked if Chalamet pulls off a dramatic last-minute upset.

Best Actress: Demi Moore has a fair chance 

Demi Moore (The Substance) has swept the Golden Globes, Critics Choice, and SAG Awards. But with Anora’s Mikey Madison taking the BAFTA and I’m Still Here’s Fernanda Torres still in play, Moore’s victory lap could be premature.

Best Supporting Actor: Could Kieran Culkin lose?

Kieran Culkin (A Real Pain) has dominated awards season. Could someone else steal the statue? Sure. But at 87.7% likelihood, this one looks locked in.

Best Supporting Actress: This could be a clean sweep for Zoe Saldana 

Despite chatter that controversy around Emilia Pérez could hurt her chances, Zoe Saldaña is sweeping through the competition. The numbers say she’s almost certain to take home gold.

Best Animated flick: The Wild Robot could go for gold

Chris Sanders has been nominated four times — but never won. At 55 per cent, The Wild Robot is the favourite. But Flow and Wallace & Gromit: Vengeance Most Fowl are still in the game.

Best International movie: A twist in the tale

Emilia Pérez was expected to dominate — but controversy, critic-audience divides, and I’m Still Here gaining ground could mean a shocking upset.

Final Thoughts: Who will win, who’ll lose

There’s no such thing as a sure thing at the Oscars — but if the data is right, expect major moments, potential heartbreaks, and perhaps a few historic wins.
