NYUAD researchers develop affordable sensing system to restore sense of touch in minimally invasive surgery
Abu Dhabi, UAE: Researchers from NYU Abu Dhabi's Advanced Microfluidics and Microdevices Laboratory (AMMLab) have developed an innovative sensing system that restores the missing tactile feedback in minimally invasive surgery (MIS), enhancing precision, ease of use, and safety. 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 NYU Abu Dhabi 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. It is the first solution to separate the sensing mechanism from the surgical site itself. This solution offers a simplified, cost-effective alternative that seamlessly integrates with any commercially available laparoscopic tool, addressing challenges related to sensor integration, wiring complexity, contamination, and sterilization requirements.
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 revolutionized 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. "Our new system restores this missing sense of touch, giving surgeons real-time data on tissue stiffness and thickness. This 'off-the-jaw' approach not only eliminates contamination risks but also makes the technology easier to integrate without requiring complex modifications to existing surgical tools."
"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. "Looking ahead, we plan to refine this system for robotic-assisted surgeries and explore even more sensitive microfluidic-based sensors for enhanced tissue differentiation."

Arizona's water is vanishing before AI gets a crack at it
Mark Gongloff, Tribune News Service While we worry about the growing threat of robots guzzling up America's groundwater, we can't ignore the risk that cows will consume it all first. A new study by researchers at Arizona State University put the depth of our water problem in perspective. It found that groundwater in the lower Colorado River basin — a region filling up with both data centres for artificial intelligence and alfalfa farms to feed cows — is being depleted far more quickly than surface water from reservoirs such as Lake Mead and Lake Powell, which are also vanishing rapidly. Nearly 28 million acre-feet of water has disappeared from aquifers since 2003, satellite measurements suggest, compared with about 14 million acre-feet from surface reservoirs. The vast majority of this water was underneath Arizona, 60% of which is suffering from extreme drought after its hottest, driest stretch in recorded history. One acre-foot of water is enough to flood an acre of land, or one American football field, with a foot of water. Twenty-eight million acre-feet is roughly the entire capacity of Lake Mead, the biggest reservoir in the US, which provides water for 20 million Americans. The actual Lake Mead receives a lot more attention. The white 'bathtub ring' showing how far its water line has fallen — it's at just 32% of capacity as of this writing — has long demonstrated that a notoriously dry region is getting even thirstier as the planet heats up and droughts become more frequent and intense. But quietly, below the ground, one entire Lake Mead has already disappeared. It will take millennia to replenish. 'People used to say the Colorado River was the lifeblood of the Southwest US,' Arizona State professor Jay Famiglietti, the study's senior author, told me. 'Now it's the groundwater. We need to make sure we take precautions to sustain that groundwater for multiple generations in the future.' The report comes at a time of growing alarm about the water and power demands of the AI boom. Every time you ask a robot to write your Ethics 101 term paper or generate one of those brainrot videos all the kids are watching these days, a data center somewhere takes a drink (essentially). Water is used to cool the servers cooking up this slop, and it's also used in generating the electricity that powers those massive computers. A study last year by the University of California, Riverside, for the Washington Post estimated that one 100-word email written by ChatGPT consumes more than a 16-ounce bottle of water. By 2028, US data centers could swallow 74 billion gallons of water per year, up from less than 6 billion in 2014, according to a December study by the Lawrence Berkeley National Laboratory. And those servers are thirstier depending on where they're situated. In Arizona, that same 100-word email would consume about two bottles of water, according to the Post/UC Riverside study. Unfortunately, Arizona and other desert locales are prime real estate for data centers. The Grand Canyon State is home to 26 new server farms built or planned since 2022, according to Bloomberg News, joining hundreds of others cropping up in areas of the U.S. under high water stress, as defined by the nonprofit World Resources Institute. Friendly regulation, abundant empty land, low humidity and a relative lack of natural disasters (unless you count flesh-searing heat) help explain Arizona's allure to server farmers. They also help explain its allure to farmer farmers — whose runaway water use makes AI look as water-stingy as a Dune Fremen in comparison. Arizona farms used about 4 billion gallons of water every day, on average, between 2010 and 2020, according to a U.S. Geological Survey report, or nearly 1.5 trillion gallons a year, accounting for 72% of the state's total water use. Those 74 billion gallons that US data centers might drink in 2028 wouldn't keep Arizona farms in business for a month. (Heck, golf-course irrigation in Maricopa County alone used nearly 31 billion gallons in 2015, according to that USGS report.) And most of this water is used to grow food for cows. A study last year in the journal Communications Earth & Environment found nearly a third of all Colorado River water use — about 6.24 million acre-feet per year, on average, or nearly a quarter of one whole Lake Mead — irrigated alfalfa and grass hay between 2000 and 2019. All other crops used just 3.85 million acre-feet, roughly matching the water used by cities. All that hay is used to feed beef and dairy cows. And about a fifth of it grown in seven Western states is exported to China, Japan, Saudi Arabia and other countries, according to a 2023 study by University of Arizona researchers. In other words, we are literally exporting our dwindling water supply. Pumping groundwater makes the land above it sink. A study earlier this month in the journal Nature found that the 28 most populous U.S. cities were sinking to some degree or another, mostly because of groundwater depletion. They have nothing on Arizona, parts of which have fallen as much as 18 feet over several decades as the water disappeared beneath them. Wells have gone dry, and giant fissures have opened in the land, wrecking homes and infrastructure. Despite all the damage their pumping wreaks, farmers and the politicians supporting them fight furiously for their right to keep doing it. Though Arizona has some sound water-management practices, including designated water-management areas that have helped stop the bleeding in Phoenix, Tucson and other places, most of the state's groundwater is still unregulated. When Governor Katie Hobbs proposed creating a new management area in the Willcox Basin in the southeast corner of the state, where the land is sinking by 3 ½ inches a year, the farmers protested. To Hobbs' credit, she created the management area anyway. Now the locals are fighting a proposal to cut their groundwater use by 50% in 50 years. President Donald Trump has made matters worse by freezing $4 billion in Inflation Reduction Act funding earmarked for protecting the Colorado River. Securing the water supply of millions of Americans in one the fastest-growing regions in the country deserves more research and funding, not less. Other possible solutions include encouraging farmers to fallow their land, transition to less-thirsty crops or sell their water rights to urban developers. And of course, Americans could always stand to eat much less beef. As for those robots, they might have an easier time using less water. Microsoft Corp. already has plans for data centers that consume none at all. Competitors will probably want to follow suit, if only to calm a growing backlash. And if we must live with AI, then maybe we can at least get it to figure out how to spend less water on cows.

Discovery of wartime bombs prompts large-scale evacuation in Cologne
Thousands of people were evacuated from central Cologne in western Germany on Wednesday following the discovery of three wartime bombs, in what the city authority called the largest such operation since the end of World War II. An evacuation zone with a radius of 1,000 metres was cleared from 8:00 am (0600 GMT), impacting around 20,500 residents along with many workers and hotel guests in the city's old town and Deutz district. Three American bombs, each with impact fuses, were found during construction work on Monday in Deutz, a bustling area on the bank of the River Rhine. Bomb disposal experts plan to disarm the ordnance later on Wednesday. Unexploded bombs are often found in Germany, where many major cities sustained heavy damage during the war. The evacuation area includes one hospital, two retirement homes, nine schools, and many hotels and museums. "Everyone involved hopes that the defusing can be completed in the course of Wednesday. This is only possible if all those affected leave their homes or workplaces early and stay outside the evacuation area from the outset on that day," the city authority said in a statement. The measures caused major transport disruptions in the city of over a million people, with Germany's national rail operator warning that many trains would be diverted or cancelled. A stretch of the Rhine will be blocked off before the bomb disposal operation begins. The Rhine, which runs from the Swiss Alps to the North Sea via Cologne, is one of Europe's key waterways for the transportation of commodities such as grain and coal. Private television station RTL, whose main office is located in the evacuation zone, interrupted its morning news programme.

Israeli strike kills dozens near US aid centre in Rafah
Al-Aqsa TV has cited Gaza's Emergency and Ambulance Service as saying that at least 23 bodies have been retrieved and more than 200 people wounded following Israeli shelling and gunfire near a US aid distribution centre west of Rafah. The attack reportedly targeted Palestinians making their way to receive food aid. The Euro-Mediterranean Human Rights Monitor condemned the strike, accusing Israel of weaponising humanitarian relief and using it as "an additional tool within the system of genocide" against Palestinians. According to the group, the aid distribution site was under its supervision and managed in cooperation with an American company. The strike on the aid point west of Rafah left dozens dead and injured, deepening already dire concerns over the targeting of civilians seeking life-saving assistance.
