Brainiacs at Northeastern University, MIT, and IBM Research in the US teamed up to create the 1980s-esque fashion statement, according to a paper quietly emitted via arXiv in mid-October.This means the wearer could slip past visitor or intruder detection systems, and so on.That means the pattern on the shirt has been carefully designed to manipulate just the right parts of a detection system's neural network to make it misidentify the wearer.“We highlight that the proposed adversarial T-shirt is not just a T-shirt with printed adversarial patch for clothing fashion, it is a physical adversarial wearable designed for evading person detectors in a real world,” the paper said.In this case, the adversarial T-shirt helped a person evade detection.The two convolutional neural networks tested, YOLOv2 and Faster R-CNN, have been trained to identify objects.
That’s to say the models can be deceived by specially crafted patches attached to real-world targets.Most research in adversarial attacks involves rigid objects like glass frames, stop signs, or cardboard.In a preprint paper, they claim it manages to achieve up to 79% and 63% success rates in digital and physical worlds, respectively, against the popular YOLOv2 model.Incidentally, the university team speculated that their technique could be combined with a clothing simulation to design such a T-shirt.The researchers from today’s study note that a number of adversarial transformations are commonly used to fool classifiers, including scaling, translation, rotation, brightness, noise, and saturation adjustment.But they say these are largely insufficient to model the deforming cloth caused by a moving person’s pose changes.
The University of Cincinnati will lead a new National Science Foundation research center to protect electronics and networked systems from sabotage, hacking or spying.The Center for Hardware and Embedded Systems Security and Trust will be UC's latest industry-university Cooperative Research Center."Building consumer trust in technology is central to our work," said Emmert, who will serve as director of the new center and principal investigator of the project.The National Science Foundation will fund the center with an initial $4.5 million grant for UC and its academic partners: the University of Virginia, the University of Connecticut, Northeastern University, the University of Texas at Dallas and the University of California, Davis.The center will work with private companies, government agencies and nonprofits that will contribute annual membership fees of as much as $50,000 to investigate their unique vulnerabilities.The private members include companies such as Adaptive Computing, financial consultants Booz Allen Hamilton and educational publisher Wiley.

Scientists at Northeastern University have created a wearable device that claims to be able to predict aggressive outbursts from autistic people a minute before the outburst happens.The wearable device is designed to alert caretakers when stress levels are nearing the point where an aggressive episode could happen.The device was created by a behavioral scientist called Matthew Goodwin.Goodwin’s device is meant to be worn on the wrist.He notes that autistic people have higher levels of stress at resting levels than people who don’t have autism.Goodwin says that their stress levels are already at the ceiling and it takes very little to push them over the edge to an aggressive event.
The Big Four US wireless carriers are reportedly throttling mobile video content regardless of whether their networks are being overloaded, according to a study conducted by researchers from Northeastern University and the University of Massachusetts Amherst.Throttling is when telecoms lower video quality and speeds for mobile subscribers to stem bandwidth demands placed on their networks.The study, which collected data from 650,000 tests in the US between January 2018 and January 2019, observed throttling rates around the clock and not just during peak times of use.US carriers were also found to throttle certain video streaming apps more often than others: AT for instance, throttled YouTube 74% of the time and Netflix 70% of the time, but wasn't found to slow down speeds for Amazon Prime Video.The practice of throttling has become more prevalent and necessary for carriers since the revival of unlimited plans in the past few years.These plans eliminated the overage fees that subscribers were once charged for exceeding their data limits, meaning US consumers have less reason to curb their mobile video consumption habits.
For people with autism, aggressive outbursts may be the only external signs of stress that’s been building up inside — seemingly unpredictable moments that can startle even their trusted caretakers.But there are more subtle signs of distress that wearables can detect and communicate in advance, a Northeastern University research team has discovered, offering caregivers a precious minute of advance awareness to prepare for and possibly mitigate the issue.The fundamental challenge is in helping people with autism to communicate their distress to caregivers before it reaches the boiling point of an outburst, an issue due to the high resting levels of stress and verbal communication challenges some people face.To an outside observer, the outburst might appear to come from nowhere, even though an unspoken stressor was quietly ratcheting up the tension.To measure the stress leading to episodes, Northeastern professor Matthew Goodwin developed a wearable that monitors a person’s heart rate, sweat production, skin temperature, and arm movements, all synchronized to a clock so that changes can be mapped to specific times when outbursts occurred.After 87-hour initial tracking periods, Goodwin’s data was able to predict future aggressive outbursts one minute in advance with 84% accuracy.
Your suspicions that your carrier is throttling your streaming service of choice are very likely true.A new study by researchers from Northeastern University and University of Massachusetts Amherst has found that throttling of online video is pervasive and happens in multiple regions across the globe, including the U.S.The research was conducted with the help of an app called Wehe, which analyzes internet speeds.More than 126,000 users from around the globe, using 2735 different providers in 183 countries downloaded the app.The findings show that throttling regularly takes place on both mobile data and Wi-Fi in seven countries.In the U.S., researchers claim AT throttled Netflix traffic 70% of the time, YouTube 74% of the time, while Amazon Prime Video was not affected.
A new report by researchers at Northeastern University confirms that the nation’s four major wireless carriers throttle at least some video content on their networks, and suggests a few workarounds for those who want the best possible video quality on their mobile devices.AT, Sprint, T-Mobile, and Verizon all note on their websites that their cheapest "unlimited" plans only allow DVD-quality video.If you want high-definition streaming, you'll need to pay an extra $8 a month for the "AT Unlimited & More Premium" service.The Northeastern report comes a little more than a year Obama-era Federal Communications Commission rules that prohibited telecom companies from throttling, blocking, or otherwise discriminating against lawful content lapsed, after the Trump-appointed FCC voted to repeal them.YouTube and some other video providers will serve 480p or lower resolution video instead of high-definition video if they detect that a user has a slow connection.Carriers that limit the quality of video often do that by scanning data in the transmission identifying it as a video.
Wireless carriers have long said they may throttle, or slow down, data when mobile networks are congested, but a new study suggests your video viewing might be getting slowed down even when networks aren't overcrowded.Researchers at Northeastern University and University of Massachusetts Amherst found that carriers throttle online video whether their mobile networks are congested or not.Location and time of day also appeared to have little impact, the researchers said.All four main carriers -- AT, Sprint, T-Mobile and Verizon -- were found to be throttling, according to the study, released Monday.The researchers collected data from more than 600,000 tests in the US using the Wehe app, which measures if provider is throttling speeds, between January 2018 and January 2019.Globally, they collected data from more than 1 million tests.
As artificial intelligence is used to make more decisions about our lives, engineers have sought out ways to make it more emotionally intelligent.To achieve this, tech companies like Microsoft, IBM, and Amazon all sell what they call “emotion recognition” algorithms, which infer how people feel based on facial analysis.For example, if someone has a furrowed brow and pursed lips, it means they’re angry.But the belief that we can easily infer how people feel based on how they look is controversial, and a significant new review of the research suggests there’s no firm scientific justification for it.“Companies can say whatever they want, but the data are clear,” Lisa Feldman Barrett, a professor of psychology at Northeastern University and one of the review’s five authors, tells The Verge.“Would you want that in a court of law, or a hiring situation, or a medical diagnosis, or at the airport ... where an algorithm is accurate only 30 percent of the time?”
Software that purportedly reads emotions in faces is being deployed or tested for a variety of purposes, including surveillance, hiring, clinical diagnosis, and market research.But a new scientific report finds that facial movements are an inexact gauge of a person's feelings, behaviors or intentions."It is not possible to confidently infer happiness from a smile, anger from a scowl or sadness from a frown, as much of current technology tries to do when applying what are mistakenly believed to be the scientific facts," a group of leading experts in psychological science, neuroscience and computer science write in their comprehensive research review.The report appears in Psychological Science in the Public Interest, a journal of the Association for Psychological Science, and is authored by Lisa Feldman Barrett of Northeastern University, Ralph Adolphs of the California Institute of Technology, Stacy Marsella of Northeastern University and the University of Glasgow, Aleix M. Martinez of The Ohio State University and Seth D. Pollak of the University of Wisconsin-Madison.The authors note that the general public and some scientists believe that there are unique facial expressions that reliably indicate six emotion categories: anger, sadness, happiness, disgust, fear, and surprise.A scowl or a smile can express more than one emotion depending on the situation, the individual or the culture, they say.
A new study demonstrates, for the first time, that "social robots" used in support sessions held in pediatric units at hospitals can lead to more positive emotions in sick children.Traditional interventions include therapeutic medical play and normalizing the environment through activities such as arts and crafts, games, and celebrations.But results also indicated that children playing with Huggable experienced more positive emotions overall.Although it is a small study, it is the first to explore social robotics in a real-world inpatient pediatric setting with ill children, the researchers say."It's a companion," says co-author Cynthia Breazeal, an associate professor of media arts and sciences and founding director of the Personal Robots group."Our group designs technologies with the mindset that they're teammates.
A newly identified genus and species of worm-like, freshwater clam, commonly known as a shipworm, eats rock and expels sand as scat while it burrows like an ecosystem engineer in the Abatan River in the Philippines.Local residents of Bohol Island tipped off an international group of scientists, including University of Amherst post-doctoral researcher Reuben Shipway, to the watery location of the bivalve, which the scientists named Lithoredo abatanica, using the Latin words for rock (litho) and the last two syllables of shipworm (teredo).Locals call the shipworm "antingaw," and new mothers are said to eat them in an effort to enhance lactation, Shipway says."These animals are among the most important in the river and in this ecosystem," says Shipway, a marine biologist working in the microbiology lab of professor Barry Goodell and lead author of the paper that describes L. abatanica, published in the Proceedings of the Royal Society B."As they bore elaborate tunnels in the limestone bedrock, these animals change the course of the river and provide a really rich environment for other aquatic species to live in.Co-authors include Marvin Altamia and Daniel Distel of Ocean Genome Legacy Center at Northeastern University, where Shipway previously worked; Gary Rosenberg of Drexel University; Gisela Concepcion of the University of the Philippines; and Margo Haygood of the University of Utah.
It also skews the results of animal research, as a new paper out this week describes.Animals used in experiments are still overwhelmingly male, thanks to outdated stereotypes that hormones like estrogen can distort an experiment’s findings.In her paper, published Thursday in Science, she outlines the long history of relying on male lab animals, particularly mice, for studies looking into the latest experimental drug or better understanding neurological illness.Historically, male mice are thought to be less of a hassle to use in experiments since they don’t go through estrus, or a menstrual period.The hormonal changes female mice go through while on their period, it’s been assumed, could affect how they respond to a drug or their brain scan results.In some cases, for certain behavioral traits, there were actually more differences among male mice than between females.
DoS cyber-attacks are not just for websites, they may also be for aircraft ILSVideo Aircraft instrument landing systems (ILS) are susceptible to radio signal spoofing using off-the-shelf equipment, boffins have found, calling into question the adequacy of aviation cybersecurity.In a research paper titled "Wireless Attacks on Aircraft Instrument Landing Systems," scheduled to be presented at the 28th USENIX Security Symposium in August, computer scientists Harshad Sathaye, Domien Schepers, Aanjhan Ranganathan, and Guevara Noubir demonstrate that it's possible to interfere with ILS data in real-time, potentially causing aircraft to discontinue a landing approach ("go around") or miss the landing area entirely in a low-visibility situation.The researchers, based at Northeastern University in Boston, USA, are also scheduled to demonstrate some of their findings today at ACM WiSec 2019."If a human is completely out of the loop, then this is possible," he told us today, adding that could become more of an issue in the years to come if fully automated landings become common.But the more immediate concern is that malicious individuals may use this technique to disrupt airport operations by tricking pilots into aborting landing attempts.
Less than two weeks ago, a Twitter account highlighting one of the cardinal sins of bad science journalism popped up online, catching the eye of scientists, reporters, and the public: @justsaysinmice.Helmed by James Heathers, an Australian native and early career data scientist at Northeastern University in the US city of Boston, the account has “fixed” articles concerning everything from potential cancer and dementia treatments to nutritional advice.Since its first tweet on 12 April—correcting an article warning about the possible hazards of a keto diet (in mice)—Heathers’ account has amassed over 44,000 thousand followers and counting, all with only around two dozen tweets so far.We caught up with Heathers and talked about his “pre-coffee” idea to start @justsaysinmice, the newfound attention it’s brought him, and whether any of his targets have issued mea culpas.The following conversation has been edited and condensed for clarity.James Heathers: Because if you conflate research in cells, yeasts, mice, or rats with human research—especially if it’s about drugs or health, which is a lot of science news—you get a very overheated, skewed idea of where that research is.
Civil rights groups, lawmakers, and journalists have long warned Facebook about discrimination on its advertising platform.But their concerns, as well as Facebook’s responses, have focused primarily on ad targeting, the way businesses choose what kinds of people they want to see their ads.A new study from researchers at Northeastern University, University of Southern California, and the nonprofit Upturn finds ad delivery—the Facebook algorithms that decide exactly which users see those ads—may be just as important.Last month, the social network settled five lawsuits from civil rights organizations that alleged companies could hide ads for jobs, housing, and credit from groups like women and older people.As part of the settlement, Facebook said it will no longer allow advertisers to target these ads based on age, gender, or zip code.But those fixes don’t address the issues the researchers of this new study found.
In a collaboration between the U.S. Department of Energy's Ames Laboratory and Northeastern University, scientists have developed a model for predicting the shape of metal nanocrystals or "islands" sandwiched between or below two-dimensional (2D) materials such as graphene.Ames Laboratory scientist are experts in 2D materials, and recently discovered a first-of-its-kind copper and graphite combination, produced by depositing copper on ion-bombarded graphite at high temperature and in an ultra-high vacuum environment.This produced a distribution of copper islands, embedded under an ultra-thin "blanket" consisting of a few layers of graphene."Because these metal islands can potentially serve as electrical contacts or heat sinks in electronic applications, their shape and how they reach that shape are important pieces of information in controlling the design and synthesis of these materials," said Pat Thiel, an Ames Laboratory scientist and Distinguished Professor of Chemistry and Materials Science and Engineering at Iowa State University.Ames Laboratory scientists used scanning tunneling microscopy to painstakingly measure the shapes of more than a hundred nanometer-scale copper islands.The model served to explain the data extremely well.
Bigots, racists and haters rejoice!You are going to get bias out of the boxFacebook has been taking a lot of stick over discrimination on its platform but a new paper suggests that the problems with the platform could go deeper.After three years of criticism that its ad system allows advertisers to unlawfully discriminate, Facebook last month announced changes to its ad platform intended to prevent advertisers from deploying unfair credit, employment and housing ads.In a paper titled, "Discrimination through optimization: How Facebook’s ad delivery can lead to skewed outcomes," co-authors Muhammad Ali, Piotr Sapiezynski, Miranda Bogen, Aleksandra Korolova, Alan Mislove, and Aaron Rieke find that advertiser budgets and ad content affect ad delivery, skewing it along gender and racial lines even when neutral ad targeting settings are used.Such segregation may be appropriate and desirable for certain types of marketing pitches, but when applied to credit, employment and housing ads, the consequences can be problematic.
A new study says that Facebook’s ad delivery algorithm discriminates based on race and gender, even when advertisers are trying to reach a broad audience.Even if an ad is targeted broadly, Facebook will serve it to the audiences most likely to click on it, generalizing from information from their profile and previous behavior.Its authors tested whether job listings or housing ads with certain keywords or images would be automatically delivered more often to certain groups, exposing what they call “previously unknown mechanisms” that could violate anti-discrimination rules.The researchers spent over $8,500 on ads that they say reached millions of people, linking to actual job-hunting or real estate sites, among other categories.Spending rates also seemingly affected who saw the ad.The researchers stress that they still don’t really know why Facebook’s algorithm is making any of these decisions.
Facebook’s ad targeting systems automatically skew the delivery of ads based on gender, race and other characteristics, even when advertisers specify that they’d like their ads to run in front of a broad audience, a new study concluded.Researchers from Northeastern University, the University of California and the digital rights nonprofit Upturn spent more than $8,500 on Facebook ads to see how ads were delivered through Facebook’s systems even when they controlled for factors like their targeting parameters, bidding strategies and the ads’ runtimes.In a study, released Wednesday, they concluded that in their experiments, Facebook’s automated ad placements “can lead to potentially discriminatory ad delivery, even when advertisers set their targeting parameters to be highly inclusive.”While they can’t conclude whether Facebook’s entire ad platform is affected, the results nonetheless “paint a distressing picture of heretofore unmeasured and unaddressed skew that can occur in online advertising systems,” the researchers wrote.Tech platforms like Facebook generally say in their terms of service that they do not allow for advertisers to place discriminatory ads on their platforms.For this study, though, researchers set out not to see how advertisers might be able to misuse the targeting options, but rather looked at “to what degree and by what means advertising platforms themselves play a role in creating discriminatory outcomes.”
A newly published research paper suggests that Facebook's ad delivery system discriminates along racial and gender lines, even when advertisers target their content to a wide audience.Researchers spent $8,500 on ads, and found that housing and job ads were shown to different demographics even though they were set to be targeted at identical audiences.This comes on the heels of US housing officials' recent charge that Facebook enables housing discrimination.The paper was put together by six researchers from Boston's Northeastern University, the University of Southern California, and policy group Upturn.The researchers spent $8,500 running dozens of ads on the platform to determine whether Facebook's ad targeting was skewing certain ads towards or away from certain groups.Read more: Facebook is facing new housing discrimination charges from the US Department of Housing and Urban Development
McGlashan is among 49 others involved in a bribery ring involving parents, admissions counselors, and athletic coaches at Yale, Wake Forest, and the University of Southern California (USC), among other institutions as they shelled out big bucks to secure spots for their children at the schools.“As a result of the charges of personal misconduct” against McGlashan, said the firm just now, Jim Coulter, Co-CEO of TPG, will be “interim managing partner” of the parts of TPG that McGlashan oversees, including TPG Growth and The Rise Fund.Coulter will, in partnership with the organization’s executive team, lead all investment work for both going forward,” according to a statement sent us just now by the firm.Others include actresses Felicity Huffman and Lori Loughlin.For McGlashan especially, whose job, is ostensibly to make a measurable, beneficial social or environmental impact, the charges are particularly damning, highlighting as they do how wealthy families sometimes use their financial muscle in socially unjust ways — in this case, paying to secure spots at colleges and depriving deserving students of admission in the process.Indeed, TPG seemingly had little choice but separating from McGlashan, at least for now.
- In the blink of an eye, the squid's "smart skin" switches color and pattern for the purpose of camouflage or sexual signaling, a virtuosic display that has long fascinated scientists.Now, collaborators from Northeastern University and the Marine Biological Laboratory (MBL) report a paradigm-shifting discovery in how specialized organs in squid skin, called chromatophores, contribute to the feat via an elegant interplay of pigmentary action and structural coloration.Their study, which brings bio-inspired engineers ever closer to building smart skin, is published in Nature Communications.Deravi and MBL Senior Scientist Roger Hanlon, a leading expert on camouflage in cephalopods (squid, octopuses, and cuttlefish), led an interdisciplinary team of researchers to investigate squid dynamic coloration on a molecular level.Squid skin contains two types of structures that manipulate light to produce various colors.When light strikes the pigment granules, they absorb the majority of the wavelengths and reflect back only a narrow band of color.
