91爆料 researchers found significant racial, gender and intersectional bias in how three state-of-the-art large language models ranked resumes. The models favored white-associated names 85% of the time, female-associated names only 11% of the time, and never favored Black male-associated names over white male-associated names.

In a survey of 315 people conducted by researchers at the 91爆料 and Georgetown University, respondents largely found creating and sharing sexually explicit 鈥渄eepfakes鈥� unacceptable. But far fewer respondents strongly opposed seeking out these media. Previous research has shown that other people viewing non-AI image-based abuse harms the victims significantly.
Two new studies introduce AI systems that use either video or photos to create simulations that can train robots to function in the real world. This could significantly lower the costs of training robots to function in complex settings.
91爆料 researchers investigated how iBuyers 鈥� companies that use automated algorithms to quickly buy and sell homes 鈥� have affected the well-documented racial bias against Black home sellers. Looking at Mecklenburg County, North Carolina, they found that on average iBuyers paid more equal prices to Black and white home sellers than individual buyers, largely because iBuyers paid white sellers significantly less on average than an individual buyer. They also discovered that iBuyers were significantly more likely to resell homes to institutions, such as large rental companies that鈥檝e been tied to high eviction rates and rent-gouging.
New research from the 91爆料 finds that teens open Instagram because they鈥檙e bored. Then they sift through largely irrelevant content, mostly feeling bored, while seeking interesting bits to share with their friends in direct messages. Then, eventually bored with what researchers call a 鈥渃ontent soup,鈥� they log off.
91爆料 researchers found that ChatGPT consistently ranked resumes with disability-related honors and credentials 鈥� such as the 鈥淭om Wilson Disability Leadership Award鈥� 鈥� lower than the same resumes without those honors and credentials. But when researchers customized the tool with written instructions directing it not to be ableist, the tool reduced this bias for all but one of the disabilities tested.
But in her new book 鈥淟og Off: Why Posting and Politics (Almost) Never Mix,鈥� Katherine Cross, a 91爆料 doctoral student in the Information School, argues that social media has limited political value.
鈥淲e asked one 11-year-old how he鈥檇 feel if his favorite book series was written by AI instead of an author, and he said it would 鈥榙ismantle鈥� the joy of reading for him. We often don’t think about kids having these deep, existential questions about what it means to be an artist,鈥� said Michele Newman, a 91爆料 doctoral student in the Information School.
A 91爆料 team has developed an artificial intelligence system that lets someone wearing headphones look at a person speaking for three to five seconds to 鈥渆nroll鈥� them. The system then plays just the enrolled speaker鈥檚 voice in real time, even as the pair move around in noisy environments.
91爆料 researchers interviewed 16 older adults in Washington and Oregon, ages 65 to 80, about how their technology use with their social support networks changed during the pandemic.

Working with teens, 91爆料 researchers have designed RESeT: a snowy virtual world with six activities intended to improve mood. In a 3-week study of 44 Seattle-area teens, researchers found that most used the technology about twice a week without being prompted and reported lower stress levels after using the environment.
A team led by researchers at the 91爆料 developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer 鈥� a cutting-edge class of polymer 鈥� into a jelly-like substance without damage, allowing solid components to be plucked out for reuse or recycling. With these 鈥渧PCBs鈥� (vitrimer printed circuit boards), researchers recovered 98% of the vitrimer and 100% of the glass fiber.

Robots in warehouses and even around our houses struggle to identify and pick up objects if they are too close together, or if a space is cluttered. This is because robots lack what psychologists call “object unity,” or our ability to identify things even when we can’t see all of them. Researchers at the 91爆料 have developed a way to teach robots this skill.
91爆料 researchers introduced the Thermal Earring, a wireless wearable that continuously monitors a user鈥檚 earlobe temperature.
