When an individual has cancer, or any number of other diseases, early detection can make a huge difference in the outcome.A research team led by the University of Notre Dame is working to cut the test time for disease biomarkers.The new timeline -- 30 minutes instead of 13 hours -- uses even smaller sample sizes to offer a new liquid biopsy option.The difference is an integrated microfluidics platform developed at Notre Dame that uses extracellular vesicles (EVs) containing microRNAs (miRNAs) as biomarkers for early-stage disease diagnosis."Extracellular vesicles contribute to intercellular communication, especially during specific cellular processes such as coagulation or immune responses," said Hsueh-Chia Chang, co-lead of the study and Bayer Professor of Chemical and Biomolecular Engineering at Notre Dame."More importantly, we are just now learning that EVs and the microRNA they carry also play a role in disease proliferation.
Photoshop played an outsize role in the odious college admissions scandal that broke earlier this year.Rick Singer, the concierge to the stars who pleaded guilty in March to money laundering and racketeering in a scheme to get rich children into luxury-brand colleges, used the software to graft the heads of teens onto the muscled bodies of elite athletes.But then there she was: my own partial profile awkwardly under a deadly serious swimming cap, atop a muscular neck, broad shoulders, thick biceps and triceps, a performance one-piece—my splendid physique waist-deep in sky-blue pool water, at keen presence to a polo ball.Water polo is widely praised as the most horrifying Olympic sport—vicious handball, but with the exciting lung sensations of waterboarding.She—me, in the picture—was like one of the aboveground real people in Jordan Peele’s Us; I was her deformed and indolent Tethered, and our reunion made me whole.The message to their children, as Eileen Kennedy-Moore, a clinical psychologist, told MarketWatch, was “I don’t have faith that you are capable of succeeding based on your own skills and hard work, and I don’t believe you’re strong enough to cope with disappointment.” An ego-stroking deepfake, to the extent that it’s supposed to look real, sends the same demoralizing message.

That's because they typically must set up an account with a third party, say a credit card company, to protect against fraud while simultaneously increasing the comfort level of potential buyers.That can result in lower profits for artists and other online sellers and higher prices for buyers.Bhaskar Krishnamachari, a professor at the USC Viterbi School of Engineering, and Aditya Asgaonkar - a recent undergraduate computer science alum at BITS Pilani, India who visited and worked with Krishnamachari at USC Viterbi over several months in 2018 - believe they have found a way to make the buying and selling of digital goods less costly, more efficient, and less vulnerable to fraud.Their proposed solution involves blockchain, "smart contracts," and game theory."Our scheme offers potentially a big improvement over the state-of-the-art in electronic commerce because it allows buyers and sellers to interact directly with each other without the need for third-party mediators of any kind," said Krishnamachari, a Ming Hsieh Faculty Fellow in Electrical and Computer Engineering and director of the Viterbi Center for Cyber-Physical Systems and the Internet of Things."It uses a dual-deposit method, escrowing a safety deposit from both buyer and seller that is returned to them only when they behave honestly.

A federal appeals court ruled this week that the practice of marking a car tires unconstitutional, a violation of your Fourth Amendment rights against unwarranted searches and seizures.For years traffic enforcement officers have marked car tires with chalk to see when they check back if a car has moved.Parking violations often serve as a key source of revenue for local municipalities.That struck a nerve with one local resident of Saginaw, Michigan.Local resident Alison Taylor took the city to court after receiving more than a dozen citations in a year, alleging a local parking enforcement officer, Tabitha Hoskins, named defendant alongside the city in the case, was violating her constitutional rights.The city initially won but the U.S. Sixth Circuit Appeals Court reversed the decision, said that chalking is a form of trespass that requires a warrant, similar to attaching a tracker to a car to monitor its real-time location, according to the court’s ruling.

Today with the advancement in the modern dentistry, the patients suffering from dental problems are able to choose from a variety of innovative dental procedures, from dental implants that may improve their ability to eat and speak and improve their perfect smile, to adult braces and Invisalign aligners made from clear, almost invisible materials.It is a crucial and very important distinction that could affect the overall outcome of your dental procedure.When selecting a dental professional for specialty related treatments such as dental implants, wisdom teeth removal, Invisalign aligners, root canals or orthodontics, it is important to make sure that you select a dental specialist like San Diego CA Dentist.Dr Qadeer at Mesa Dental Family & Cosmetic Dentistry attended the University of Southern California School of Dentistry (USC) where he graduated with deans honors and have extensive training in all dental specialty procedures.Dr Qadeer is a perfectionist and has many years of experience performing different types of procedures than a general dentist who specializes in a particular practice area.In addition, our dental specialist Dr Qadeer at Mesa Dental is highly trained to recognize and address unexpected problems or emergencies and effectively correct them and will make sure to deliver the highest level of care to all of his patients.Many dental patients avoid dental surgeries such as dental implants, Invisalign clear aligners because of fear and pain.At Mesa Dental, our team of highly trained dental specialist and staff will eliminate the fear with one rule love, and provide the best painless dental services using best anesthesia in San Diego.
From “blitzscaling” to “move fast and break things,” startups are focused on growth and speed – that’s change at scale.I see that focus in the startups in my accelerators and students in my classes at USC.But something related that we rarely talk seriously about is what happens when that growth, speed, and change affects other parts of an existing system.Humans have dealt with this disease for centuries.Even in the US, malaria was only eradicated in 1951.While in 2015 there were 212 million malaria cases and 429,000 deaths, just 20 years earlier the numbers were much higher, with estimates of 300 – 500 million cases with 3 million deaths.
Scientists have discovered a new species of ancient sea cucumber after creating a 3D computer reconstruction of the creature from a 430-million-year-old fossil.The discovery was made by a team of international palaeontologists, led by the Oxford University Museum of Natural History, using a fossil discovered in a site in Herefordshire, UK.After reconstructing the image of the tentacled creature from the fossil, the team dubbed the species Sollasina cthulhu, after the terrifying monster Cthulhu from H.P.The team at Oxford recreated the 3D by grinding away thin layers of the fossil, taking individual photographs at each stage to create a "virtual fossil."The creature had multiple "tube feet" tentacles that it used to crawl over the seafloor and capture food, according to the research team.The 3D render also revealed an internal ring -- a first-time discovery for this group of extinct creatures -- that most likely formed part of a vascular system of "fluid filled canals" the creature used to move and feed.

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.

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.

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

Scientists from the Moscow Institute of Physics and Technology (MIPT), the Skolkovo Institute of Science and Technology (Skoltech), and the University of Southern California (USC) have developed a new computational method for the design of thermally stable G protein-coupled receptors (GPCR) that are of great help in creating new drugs.The method has already proved useful in obtaining the structures of several principal human receptors.An overview of the new method was published in the prestigious science journal Current Opinion on Structural Biology.Receptors are molecules that capture and transmit signals and play a key role in the human body regulation.GPCRs are among the best-known human protein families involved in vision, olfaction, immune response, and brain processes, making them an important drug target.For a receptor to serve as a target, the researchers need to understand its structure in great detail, just as a locksmith needs to know the lock's inner structure to make a key that fits.

After all these political shenanigans, a one-way trip to the Red Planet doesn't sound so badWhile Mars looks like a sterile, bleak, and dry wasteland, pockets of salty water may lie deep beneath that rust-colored dust, according to a paper published Thursday in Nature Geoscience.There is mounting evidence that, once upon a time, the Red Planet may have been covered by a large ocean, though where it all went is still a bit of a mystery.We know water in the form of ice and vapor is present on Mars, and there are signs it also exists in liquid form: it's believed these dark streaks were created by minerals binding to water running over the alien world's surface during summertime.That surface water theory was offered by NASA in 2015.Now, stateside scientists at the University of Southern California (USC) have studied the streaks, and drawn a very different conclusion – that the dark marks were formed from underground water rising up, rather than streams of surface liquid.

But following a series of high-profile accidents in the United States, safety issues could bring the autonomous dream to a screeching halt.At USC, researchers have published a new study that tackles a long-standing problem for autonomous vehicle developers: testing the system's perception algorithms, which allow the car to "understand" what it "sees."Working with researchers from Arizona State University, the team's new mathematical method is able to identify anomalies or bugs in the system before the car hits the road.Perception algorithms are based on convolutional neural networks, powered by machine learning, a type of deep learning."Making perception algorithms robust is one of the foremost challenges for autonomous systems," said the study's lead author Anand Balakrishnan, a USC computer science PhD student.The same way cars have to go through crash tests to ensure safety, this method offers a pre-emptive test to catch errors in autonomous systems."

Now a new study points to an active groundwater system that may be lurking deep below the planet's equatorial regions, feeding a mysterious phenomenon on the Martian surface.Two researchers at the University of Southern California, Abotalib Z. Abotalib and Essam Heggy, posit that "recurring slope lineae" (RSL), dark streaks that periodically appear on the side of Martian craters, are being created by an active, deep reservoir of salty water.The study, published Thursday in Nature Geoscience, used images provided by HiRISE, a high-resolution camera aboard the NASA's Mars Reconnaissance Orbiter circling the red planet, to analyze distinct surface features.They discovered that RSL most commonly emanate from fractures and cracks in Palikir's surface.In the past scientists, have hypothesized a number of reasons the RSL appear on the side of Martian craters, including the idea that they may just be sand flows rather than a phenomenon caused by water.Other groups have suggested they're caused by seeping salt water that originates from just below the surface.
Music is an ever-present companion for many of us, and its impact is undeniable.You know music makes you move and triggers emotional responses, but how and why?In the latest episode of Tech Effects, we tried to find out.Our first stop was USC's Brain & Creativity Institute, where I headed into the fMRI to see how my brain responded to musical cues—and how my body did, too.(If you're someone who experiences frisson, that spine-tingling, hair-raising reaction to music, you know what I'm talking about.)We also talked to researchers who have studied how learning to play music can help kids become better problem-solvers, and to author Dan Levitin, who helped break down how the entire brain gets involved when you hear music.

Even the most advanced of their kind, like those developed by engineers at Boston Dynamics, have taken years to evolve beyond the sure-footedness of a toddler stumbling on an ice rink.How might they find their footing?Researchers at the University of Southern California have developed a robotic leg capable of walking without preprogrammed knowledge of how to do it.It’s an impressive feat that could help future robots navigate the world independently.Inspired by animals like impala and wildebeest, whose young become skilled runners within minutes of birth, the USC limb uses a bio-inspired artificial intelligence algorithm to learn about its environment and refine its mobility.“Biological systems continue to be the inspiration and envy of roboticist — even now that we have so much computational power,” Francisco Valero-Cuevas, USC engineer and lead research on the project, told Digital Trends.

In the future, personalized AI assistants will use knowledge of our behaviors to inform us of goings-on and do chores, and as we grow older, they’ll provide companionship and assistance when caregivers aren’t around.These assistants will not only chart our calendars and supply answers to questions, but will help administer medical treatments, assist us in making difficult decisions, and connect us with the people we care deeply about.That’s the vision the Computing Community Consortium (CCC), an organization representing over 220 North American academic departments, industrial research labs, and professional societies, articulated in a draft of its 20-year roadmap for AI research in the U.S., which was published this month.Its organizers — who include University of Southern California director of knowledge technologies Yolanda Gil and Dr. Fei-Fei Li, a Stanford professor and formerly Google’s chief AI scientist — picture personal assistants that will fundamentally transform human lives around the world for the better.“[AI] will enable an elderly population to live longer independently, AI health coaches will provide advice for lifestyle choices, [and] customized AI tutors will broaden education opportunities,” according to the report.“[A]nd AI scientific assistants will dramatically accelerate the pace of discovery.”
Made after consultation with researchers and tech companies, the roadmap calls for sustained support from the federal government and prescribes a number of steps to ensure the U.S. retains its position as a nation with some of the most advanced AI resources on the planet.Create an Open AI platform that includes a collection of data sets, knowledge repositories, and libraries available to and made in part by researchers in academia, government, and business.Launch national AI competitions that challenge researchers to solve big problems and push the community to achieve state-of-the-art results.Open national research centers and AI laboratories to support the Open AI platform, competitions, and research fellows.According to the roadmap: “… lifelong personal assistants will enable an elderly population to live longer independently, AI health coaches will provide advice for lifestyle choices, customized AI tutors will broaden education opportunities, and AI scientific assistants will dramatically accelerate the pace of discovery.”Organizers believe such efforts could promote universal personalized education, accelerate scientific discovery, and drive business innovation.
