Growing up, we learn to push just hard enough to move a box and to avoid touching a hot pan with our bare hands. Now, a robot hand has been developed that also has these instincts.

The MOTIF Hand, developed by a student team in collaboration with Daniel Seita, a USC Viterbi assistant professor of computer science, is built on the idea of being multimodal—that is, having several sensory abilities. The most prominent of these abilities relate to temperature and force, with built-in sensors for depth, force and temperature allowing the hand to sense and react to these factors.

These capabilities create potential not only for better research involving robotic hands, but they also allow these hands to last longer by avoiding temperature-related damage. Force-related capabilities could also have a surprisingly practical real-world use.

“In factories and other domains, a robot would have to push to get objects into their targets, and that requires measuring some amount of force,” Seita said. “That type of force sensor can help in those cases, just to check that the robot is exerting the right amount of force.

“We haven’t seen people build this type of hand before,” he added.

Hot stuff

The MOTIF Hand builds on the foundation of the LEAP Hand, which was built by a research team at Carnegie Mellon in 2023. MOTIF’s key advancement is the addition of human-like sensory capabilities. This MOTIF Hand, which contains far more accurate human-like features and abilities, could have myriad applications, including in factory work and even cooking or welding, Seita said.

The robot’s ability to sense temperature comes from a thermal camera built into the palm of the hand. Seita and his team of USC Viterbi graduate students aimed to create a hand that would simulate a human understanding of temperature.

“If we’re cooking, we have a pot that’s very hot. We might put our hand near it to check if it’s safe to touch before we actually touch it, to avoid burns and damage,” Seita said. “We wanted that same intuition conveyed into a robot system.”

It’s an intuitive system that requires the hand to be close to the material whose temperature it’s detecting, said Hanyang Zhou, a co-author of the research paper, “The MOTIF Hand: A Robotic Hand for Multimodal Observations with Thermal, Inertial, and Force Sensors,” who recently graduated from the Viterbi School with a master’s in computer science. The paper is published on the arXiv preprint server.

“We were thinking, is it possible in some certain way to get a signal but not touch anything? So, we put an infrared-based camera right in the palm,” he added.

In other words, the MOTIF Hand can detect temperature through this thermal camera without even touching an object—just placing the hand close enough for the camera to examine it does the job.

‘You have to feel it’

The work done by Seita, Zhou and their team was designed to make the process of testing temperature and force feel more natural—in other words, true to human experiences with these things. For example, force is something that humans can’t see, just feel. The MOTIF Hand is designed around the same sensations we use to understand force-related properties, such as an object’s weight, allowing for more life-like robotic reactions to force.

“We as humans cannot distinguish [force] as a vision you have to feel it. But how is that possible for a ?” Zhou asked. “If I don’t know whether a is full of water, I just flick it. I’ll shake it, right?”

The IMU sensors built into the MOTIF Hand bring this simple test to robotics. The hand, like our own, merely needs to flick or shake an object to determine its weight.

The MOTIF Hand was based on Carnegie Mellon’s LEAP Hand, which was open source. To further advance this sensory technology, Seita and his team have promised to make the MOTIF Hand as well.

“Open-sourcing research advancement is really important to advance the community,” Seita said. “The more people that use our hand, the better it is for research.”

Zhou described the MOTIF Hand’s sensory advancements as a “platform” that he hopes the entire robotics community will build on for the future.

“We should make it easy [and] accessible for more and more research teams, as long as they are interested in such a platform,” Zhou said.

Netflix Says if the HBO Merger Makes It Too Expensive, You Can Always Cancel

Netflix Says if the HBO Merger Makes It Too Expensive, You Can Always Cancel


There is concern that subscribers might be negatively affected if Netflix acquires Warner Bros. Discovery’s streaming and movie studios businesses. One of the biggest fears is that the merger would lead to higher prices due to less competition for Netflix.

During a US Senate hearing Tuesday, Netflix co-CEO Ted Sarandos suggested that the merger would have an opposite effect.

Sarandos was speaking at a hearing held by the US Senate Judiciary Committee’s Subcommittee on Antitrust, Competition Policy, and Consumer Rights, “Examining the Competitive Impact of the Proposed Netflix-Warner Brothers Transaction.”

Sarandos aimed to convince the subcommittee that Netflix wouldn’t become a monopoly in streaming or in movie and TV production if regulators allowed its acquisition to close. Netflix is the largest subscription video-on-demand provider by subscribers (301.63 million as of January 2025), and Warner Bros. Discovery is the third (128 million streaming subscribers, including users of HBO Max and, to a smaller degree, Discovery+).

Speaking at the hearing, Sarandos said: “Netflix and Warner Bros. both have streaming services, but they are very complementary. In fact, 80 percent of HBO Max subscribers also subscribe to Netflix. We will give consumers more content for less.”

During the hearing, Democratic senator Amy Klobuchar of Minnesota asked Sarandos how Netflix can ensure that streaming remains “affordable” after a merger, especially after Netflix issued a price hike in January 2025 despite adding more subscribers.

Sarandos said the streaming industry is still competitive. The executive claimed that previous Netflix price hikes have come with “a lot more value” for subscribers.

“We are a one-click cancel, so if the consumer says, ‘That’s too much for what I’m getting,’ they can cancel with one click,” Sarandos said.

When pressed further on pricing, the executive argued that the merger doesn’t pose “any concentration risk” and that Netflix is working with the US Department of Justice on potential guardrails against more price hikes.

Sarandos claimed that the merger would “create more value for consumers.” However, his idea of value isn’t just about how much subscribers pay to stream but about content quality. By his calculations, which he provided without further details, Netflix subscribers spend an average of 35 cents per hour of content watched, compared to 90 cents for Paramount+.

The Netflix stat is similar to one provided by MoffettNathanson in January 2025, finding that in the prior quarter, on average, Netflix generated 34 cents in subscription fees per hour of content viewed per subscriber. At the time, the research firm said Paramount+ made an average of 76 cents per hour of content viewed per subscriber.

Downplaying Monopoly Concerns

Netflix views Warner as “both a competitor and a supplier,” Sarandos said when subcommittee chair Republican senator Mike Lee of Utah asked why Netflix wants to buy WB’s film studios, per Variety. The streaming executive claimed that Netflix’s “history is about adding more and more” content and choice.

During the hearing, Sarandos argued that streaming is a competitive business and pointed to Google, Apple, and Amazon as “deep-pocketed tech companies trying to run away with the TV business.” He tried to downplay concerns that Netflix could become a monopoly by emphasizing YouTube’s high TV viewership. Nielsen’s The Gauge tracker shows which platforms Americans use most when using their TVs (as opposed to laptops, tablets, or other devices). In December, it said that YouTube, not including YouTube TV, had more TV viewership (12.7 percent) than any other streaming video-on-demand service, including second-place Netflix (9 percent). Sarandos claimed that Netflix would have 21 percent of the streaming market if it merged with HBO Max.

Measles Is Causing Brain Swelling in Children in South Carolina

Measles Is Causing Brain Swelling in Children in South Carolina


Some children affected by measles in the ongoing South Carolina outbreak have developed a serious complication of the disease called encephalitis, or swelling of the brain, state epidemiologist Linda Bell said on Wednesday.

The South Carolina measles outbreak began in October with a handful of infections. As of February 3, cases have climbed to 876, with 700 of those being reported since the beginning of the year. The surge could mean another bad year of measles for the United States, which had more than 2,267 cases—the highest in 30 years—in 2025. Declining vaccination rates across the country are driving the resurgence.

Encephalitis is a rare but severe complication of measles that can lead to convulsions and cause deafness or intellectual disability in children. It usually occurs within 30 days of an initial measles infection and can happen if the brain becomes infected with the virus or if an immune reaction to the virus causes inflammation in the brain. Among children who get measles encephalitis, 10 to 15 percent die.

It’s not known how many children in South Carolina have developed this serious complication. Under state law, measles cases must be reported to the South Carolina Department of Public Health, but measles hospitalizations and complications do not need to be disclosed.

“We don’t comment on the outcomes of individuals, but we do know that inflammation of the brain, or encephalitis, is a known complication of measles,” Bell told reporters during a media briefing on Wednesday. “Anytime you have inflammation of the brain, there can be long-term consequences, things like developmental delay and impacts on the neurologic system that can be irreversible.”

The department is aware of 19 measles-related hospitalizations in the state, including some due to pneumonia, which occurs in about one in 20 children with measles and is the leading cause of death for children who get measles.

Bell also said that several pregnant women who were exposed to the virus required administration of immune globulin, a concentrated solution of antibodies. It provides temporary protection against measles for unvaccinated individuals. Measles exposure during pregnancy can cause preterm birth or miscarriage.

A rarer type of brain swelling called subacute sclerosing panencephalitis, or SSPE, can occur years after a measles infection. In September, the Los Angeles County Department of Public Health reported the death of a school-age child due to SSPE. The child was originally infected with measles as an infant before they were old enough to receive the measles vaccine, the first dose of which is recommended for children between 12 and 15 months old.

After recovering from the initial measles illness, the child developed SSPE, in which the virus remains dormant in the brain before triggering an inflammatory response that destroys brain tissue over time. The condition usually appears seven to 10 years after a person appears to recover from the initial measles infection. An estimated two in 10,000 people who get measles eventually develop SSPE.

The measles, mumps, and rubella (MMR) vaccine is the best way to prevent measles and serious complications associated with it.

Over 7,000 more doses of the MMR vaccine were given statewide in South Carolina this January compared to January 2025, a 72 percent increase. In Spartanburg County, the center of the outbreak, over 1,000 more doses were given this January compared to January 2025, a 162 percent increase. So far, January was the best month for measles vaccination during the outbreak, Bell said.
