A simple firmware update completely hides a device’s Bluetooth fingerprint
A smartphone’s unique Bluetooth fingerprint could be used to track the device’s user–until now. A team of researchers have developed a simple firmware update that can completely hide the Bluetooth fingerprint, eliminating the vulnerability. The method was developed by a team of researchers at the University of California San Diego.
Metal-loving microbes could replace chemical processing of rare earths
Cornell University scientists have characterized the genome of a metal-loving bacteria with an affinity for rare earth elements. The research paves the way towards replacing the harsh chemical processing of these elements with a benign practice called biosorption.
Smartphone Use Goes Up in City Parks, But Down in Forests
New research shows that smartphone activity actually increases during visits outdoors to city parks—a finding that contradicts popular notions. Thanks to two years of unparalleled access to 700 study participants’ smartphone data, the study is the first to show that young adults now spend far more time on their smartphone screens than in nature. The study finds that people who visit forests or nature preserves experience significant declines in screen time, compared to visits to urban locations for the same duration.
Hey Siri, Can You Hear Me? #ASA184
At the 184th ASA Meeting, Georgia Zellou and Michelle Cohn of the University of California, Davis will describe experiments to investigate how speech and comprehension change when humans communicate with AI. They examined how people adjust their voice when communicating with an AI system compared to talking with another human and, on the listening side, how what a device sounds like impacts how well listeners will understand it.
Prototype taps into the sensing capabilities of any smartphone to screen for prediabetes
Researchers at the University of Washington have developed GlucoScreen, a system that could enable people to self-screen for prediabetes.
New Technology Turns Smartphones into RFID Readers, Saving Costs and Reducing Waste
Imagine you can open your fridge, open an app on your phone and immediately know which items are expiring within a few days. This is one of the applications that a new technology developed by engineers at the University of California San Diego would enable.
FAU-developed Video Compression Technology Receives Industry Recognition
Video compression technology enables streaming video applications from YouTube to Netflix to transmit high quality video. As video accounts for about 80 percent of all Internet traffic, better video compression is a prominent issue worldwide. Technology developed by FAU researchers, in partnership with research sponsor OP Solutions, LLC, promises to improve the process of streaming media. FAU and OP Solutions have announced that industry groups within the field have accepted university-developed intellectual property as part of the next generation video codec Versatile Video Coding (VVC).
Voice-activated system for hands-free, safer DNA handling
Smart voice assistants could make the laboratory safer for scientists and technicians who handle infectious samples. Researchers in ACS Sensors now report a small, voice-activated device that can extract and pretreat bacterial DNA, helping protect those on the front lines of disease outbreaks.
Assessment of mental health services available through smartphone apps
In this study of 578 mental health apps, findings indicate that the current app marketplaces primarily offered basic features such as psychoeducation, goal tracking, and mindfulness but fewer innovative features such as biofeedback or specialized therapies.

Lithium-ion batteries that last longer in extreme cold
To improve lithium-ion batteries’ performance in extreme cold, researchers reporting in ACS Central Science replaced the traditional graphite anode with a bumpy carbon-based material, which maintains its rechargeable storage capacity down to -31 F.
Einstein Aging Study Receives $32 Million Grant to Study Alzheimer’s Disease
To help address the rising tide of Alzheimer’s disease nationwide, researchers at Albert Einstein College of Medicine in collaboration with faculty at Pennsylvania State University and other institutions, have received a five-year, $32 million grant from the National Institutes of Health (NIH) to support the ongoing Einstein Aging Study (EAS), which focuses on both normal aging and the special challenges of Alzheimer’s disease, and other dementias. EAS was established at Einstein in 1980 and has been continuously funded by the NIH.

Leveraging technology to track recovery and relapse in individuals with alcohol use disorders
Alcohol researchers have long known that excessive drinking can cause detrimental changes in cardiovascular functioning. Recent advances in technologies can facilitate data collection that identifies altered cardiovascular functioning even before a diagnosis of cardiovascular disease. These results and others will be shared at the 44th annual scientific meeting of the Research Society on Alcoholism (RSA), which will be held virtually this year from the 19th – 23rd of June 2021 due to the COVID-19 pandemic.
Taking photos can impair your memory of events
It is a common practice to photograph events that we most want to remember, such as birthdays, graduations and vacations. But taking photos can actually impair your memory for the experience, according to new research from Binghamton University, State University of New York.
Poor Grasp of Dating Violence in College Perpetuates ‘Boys Will be Boys’ Views
A study to understand the dating violence experience and perpetration of college-age women, as well as how they conceptualize violence in dating relationships, reveals normalization of unhealthy violent behaviors where sexual pressure or sexualized verbal harassment are viewed as an innate part of men, supporting the idea that “boys will be boys.” Study participants demonstrated a lack of knowledge of the forms of dating violence and its consequences. They accepted, rationalized and provided excuses for these acts of violence.
