Outsmarting deep fakes: AI-driven imaging system protects authenticity

To thwart sophisticated methods of altering photos and video, researchers at the NYU Tandon School of Engineering have demonstrated an experimental technique to authenticate images throughout the entire pipeline, from acquisition to delivery, using artificial intelligence (AI).

Sensor-packed glove learns signatures of the human grasp

Wearing a sensor-packed glove while handling a variety of objects, MIT researchers have compiled a massive dataset that enables an AI system to recognize objects through touch alone. The information could be leveraged to help robots identify and manipulate objects, and may aid in prosthetics design.

Community impacts from extreme weather shape climate beliefs

Recent studies have suggested that people who experience the impacts of hurricanes, catastrophic flooding or other severe weather events are more likely to believe in, and be concerned about, climate change in the wake of the disaster.

Maestro: a new attack that orchestrates malicious flows with BGP

Researchers at the University of Tennessee have recently identified the Maestro attack, a new link flooding attack (LFA) that leverages plane traffic control engineering techniques to concentrate botnet-sourced distributed denial of service (DDos) flows on transit links. In their paper, recently published on arXiv, the researchers outlined this type attack, tried to understand its scope and presented effective mitigations for network operators who wish to insulate themselves from it.

Finally, a tool to predict response to chemotherapy before bladder cancer surgery

University of Colorado Cancer Center led clinical trial data show that a predictive tool called COXEN may show which bladder cancer patients will respond to pre-surgical chemotherapy, a step towards allowing doctors to offer such chemotherapy to patients likely to respond, while moving more efficiently to other treatment options with patients unlikely to benefit. Results will be presented Monday, June 3 at 8:00am as oral abstract at the 2019 American Society for Clinical Oncology (ASCO) Annual Meeting (ASCO abstract #4506).

Stanford Doggo: a highly agile quadruped robot

Researchers at Stanford University have recently created an open-source quadruped robot called Stanford Doggo. Their robot, presented in a paper pre-published on arXiv and set to be published by IEEE Explore, exceeds the performance of many state-of-the-art legged robots in vertical jumping agility.

Children who nap are happier, excel academically, and have fewer behavioral problems: study

Ask just about any parent whether napping has benefits and you'll likely hear a resounding "yes," particularly for the child's mood, energy levels, and school performance. New research from the University of Pennsylvania and the University of California, Irvine, published in the journal Sleep backs up that parental insight.

Researchers add 'time-travel' feature to drives to fight ransomware attacks

One of the latest cyber threats involves hackers encrypting user files and then charging "ransom" to get them back. In the paper, "Project Almanac: A Time-Traveling Solid State Drive," University of Illinois students Chance Coats and Xiaohao Wang and Assistant Professor Jian Huang from the Coordinated Science Laboratory look at how they can use the commodity storage devices already in a computer, to save the files without having to pay the ransom.

A new molecular mechanism could explain the origins of the depressive symptoms in Huntington's disease

About 40 percent of the affected patients with Huntington's disease—a neurodegenerative pathology- show depression symptoms, even in early stages before the apparition of the typical motor symptoms of the disease. An altered function of Cdk5 kinase—an essential enzyme in several cell signalling pathways- could explain the physiopathology of the depressive-like behaviour in Huntington's disease, according to a pre-clinical study in which the UB experts Sílvia Ginés, Verónica Brito, Albert Giralt and Jordi Alberch, from the Faculty of Medicine and Health Sciences and the Institute of Neurosciences of the University of Barcelona (UBNeuro) have taken part.

Shared control allows a robot to use two hands working together to complete tasks

A team of researchers from the University of Wisconsin and the Naval Research Laboratory has designed and built a robotic system that allows for bimanual robot manipulation through shared control. In their paper published in the journal Science Robotics, the group explains the ideas behind their work and how well they worked in practice.

Pre-surgical immunotherapy shows promise in trial for patients with early stage lung cancer

For patients with operable non-small cell lung cancer (NSCLC), pre-surgical "neoadjuvant" treatment with an immune checkpoint inhibitor was well tolerated and, in many cases, caused significant tumor cell death in a large, multicenter clinical trial involving investigators at Dana-Farber Cancer Institute, Brigham and Women's Hospital, and nine other research centers. Interim results of the trial will be presented at the American Society of Clinical Oncology (ASCO) Annual Meeting.

REPLAB: A low-cost benchmark platform for robotic learning

Researchers at UC Berkeley have developed a reproducible, low-cost and compact benchmark platform to evaluate robotic learning approaches, which they called REPLAB. Their recent study, presented in a paper pre-published on arXiv, was supported by Berkeley DeepDrive, the Office of Naval Research (ONR), Google, NVIDIA and Amazon.

How the immune system keeps the Epstein-Barr virus in check

A protein called PD-1, which is found on immune cells called CD8+ T cells, plays a key role in controlling infection with the Epstein-Barr virus, according to a study published May 30 in the open-access journal PLOS Pathogens by Christian Münz of the University of Zurich, and colleagues. The results from this study indicate that monitoring PD-1 signaling during future vaccination and immunotherapy studies may inform patient outcomes.
