NYU Abu Dhabi researchers develop sensing system for 'laparoscopic surgeries'
The new "off-the-jaw" system integrates force and angle sensors into the handle of laparoscopic tools, providing surgeons with real-time measurements of grasping forces and insights into tissue stiffness and thickness.
Minimally invasive surgery (MIS) involves small incisions, reducing pain, shortening recovery times, and lowering infection risks. However, traditional MIS tools eliminate the surgeon's sense of touch, making it difficult to determine the appropriate force to apply or distinguish between different types of tissue. This lack of tactile sensation can lead to errors, such as over- or under-grasping delicate tissues.
The researchers' unique "off-the-jaw" design, detailed in IEEE Access, marks a significant departure from previous approaches, which typically placed sensors at the jaws of surgical tools.
Beyond improving surgical precision and safety, this new technology could also shorten the learning curve for new surgeons by providing objective tactile feedback, accelerating their mastery of MIS techniques. Its scalability means it could be adapted for robotic-assisted surgery, endoscopy, telemedicine, and other medical applications.
"Minimally invasive surgery has revolutionised the field, but the lack of tactile feedback remains a challenge," said NYU Abu Dhabi Associate Professor of Mechanical Engineering and Bioengineering Mohammad A. Qasaimeh.
"Early trials have demonstrated a 30 percent improvement in surgical task efficiency, highlighting the practical impact of this technology on surgical performance," added Wael Othman, Ph.D., Postdoctoral Researcher at the AMMLab.

NYUAD researchers find link between brain growth and mental health disorders
Abu Dhabi, UAE: A team of researchers at NYU Abu Dhabi has uncovered a key mechanism that helps shape how our brains are wired, and what can happen when that process is disrupted. In a new study published in Cell Reports, the RNA-MIND Lab at NYU Abu Dhabi, led by Professor of Biology Dan Ohtan Wang, with Research Associate Belal Shohayeb, reveals how a small molecular mark on messenger RNA, called m6A methylation, regulates the production of essential proteins inside growing neurons. This process plays a critical role in the development of axons, the long extensions that neurons use to connect and communicate with each other. The study shows that this molecular mark controls the production of a protein called Adenomatous Polyposis Coli (APC), which helps organize the internal structure of nerve cells and is needed to locally produce β-actin, a key building block of cytoskeleton to support axon growth. Importantly, the team also found that genetic mutations linked to autism and schizophrenia can interfere with this process, potentially affecting how the brain develops. 'This research connects a global process, how proteins are made across the cell, with highly local effects in neurons that guide brain development,' said Ohtan Wang. 'We're learning that when these finely tuned systems break down, the impact can be seen in conditions like autism and schizophrenia. Understanding these molecular details could open the door to new ways of thinking about treatment and early intervention.' As the brain forms, neurons must grow, connect, and communicate in precise ways. This research sheds light on the inner workings of that process and deepens our understanding of how even the smallest molecular changes can have far-reaching effects. The paper, "m6A RNA methylation-mediated control of global APC expression is required for local translation of β-actin and axon development," is now available online in Cell Reports.

Saudi IT Group MIS fully divests investment in US AI firm Anthropic
Saudi Arabia-listed Al Moammar Information Systems (MIS) has divested 100% of its investment in American artificial intelligence (AI) firm Anthropic for $9.33 million. The transaction generated $4.26 million in profit for MIS that will be reflected in the second-quarter 2025 financial results, the company confirmed on Tuesday. MIS earlier said it would establish an investment portfolio in global AI companies, as part of its strategy to enhance revenue streams. It initially allocated SAR 40 million for the purpose through self-financing. Last year, MIS invested $5 million in Anthropic as part of a Series D funding round.

Dubai drive to become international education powerhouse
Juwai IQI, a leading global real estate and proptech group, has highlighted that 2025 will mark big gains in Dubai's ambitions to become an international education powerhouse. Kashif Ansari, Co-Founder and Group CEO of Juwai IQI, pointed out that Dubai's has a strategy called 'Education 33' that aims to make the emirate one of the world's top-10 education destinations by 2033. That would require 10X growth in student numbers by 2033. These goals might have seemed ambitious when they were announced, but now global events have turned in Dubai's favour. Ansari believes Dubai is exceptionally well prepared to absorb the shift. The bold move to offer every Dubai resident a complimentary subscription to ChatGPT Plus is an example of its forward-looking leadership. At regular prices, that would cost the emirate nearly $80 million. 'Dubai is incredibly well placed for this moment. While other top education destinations like the UK, Canada, and Australia are limiting international student numbers, the number enrolled in Dubai's private higher education sector grew by 25% last year. 'Today, the UAE is home to more than 237,000 international students and 57 international branch campuses. Many are located in Dubai Knowledge Park and Dubai International Academic City. Abu Dhabi and Sharjah also host institutions such as NYU Abu Dhabi and the American University of Sharjah. Ansairi said Dubai will reap many benefits when it succeeds in this quest. 'Perhaps most importantly,' he said, 'it would create a thriving educational system that would provide the best opportunities to Dubai's own young people. 'It would also add another powerful export sector to the emirate's economy and boost spending in other areas such as housing, retail, and services. Every international student boosts the US economy by an average of about $44,000.'
