An international team of researchers has developed a scanning tool to make websites less vulnerable to hacking and cyberattacks.
The black box security assessment prototype, tested by engineers in Australia, Pakistan and the UAE, is more effective than existing web scanners which collectively fail to detect the top 10 weaknesses in web applications.
UniSA mechanical and systems engineer Dr. Yousef Amer is one of the co-authors of a new international paper that describes the development of the tool in the wake of escalating global cyberattacks.
An autonomous vehicle is able to navigate city streets and other less-busy environments by recognizing pedestrians, other vehicles and potential obstacles through artificial intelligence. This is achieved with the help of artificial neural networks, which are trained to “see” the car’s surroundings, mimicking the human visual perception system.
But unlike humans, cars using artificial neural networks have no memory of the past and are in a constant state of seeing the world for the first time—no matter how many times they’ve driven down a particular road before. This is particularly problematic in adverse weather conditions, when the car cannot safely rely on its sensors.
Researchers at the Cornell Ann S. Bowers College of Computing and Information Science and the College of Engineering have produced three concurrent research papers with the goal of overcoming this limitation by providing the car with the ability to create “memories” of previous experiences and use them in future navigation.
Neuro-Protection & Neuro-Regeneration R&D For Optic Pathologies — Dr. Thomas V. Johnson, MD, PhD, Johns Hopkins Medicine
Dr. Thomas V. Johnson III, M.D., Ph.D. (https://www.hopkinsmedicine.org/profiles/details/thomas-johnson) is a glaucoma specialist and the Allan and Shelley Holt Rising Professor in Ophthalmology at Wilmer Eye Institute, at Johns Hopkins University. He is also a member of the Retinal ganglion cell (RGC) Repopulation, Stem cell Transplantation, and Optic nerve Regeneration (RReSTORe) consortium (https://www.hopkinsmedicine.org/wilmer/research/storm/rrestore/index.html), an initiative focused on advancing translational development of vision restoration therapies for glaucoma and other primary optic neuropathies by assembling an international group of more than 100 leading and emerging investigators from related fields.
Dr. Johnson received his BA (summa cum laude) in Biological Sciences from Northwestern University in 2005. As a Gates-Cambridge Scholar and an NIH-OxCam Scholar, he earned his PhD in Clinical Neuroscience from the University of Cambridge (UK) in 2010. He completed his medical training (AOA) at the Johns Hopkins School of Medicine in 2014 and served as an intern on the Johns Hopkins Osler Medical Service prior to completing his ophthalmology residency and glaucoma fellowship at the Wilmer Eye Institute.
Dr. Johnson’s research interests are focused on understanding the pathophysiology of retinal and optic nerve neurodegenerative disorders, and on the development of neuroprotective and neuroregenerative therapies for these conditions. His doctoral thesis work evaluated intraocular stem and progenitor cell transplantation as a possible neuroprotective therapy for glaucoma. His research contributions have been recognized with a World Glaucoma Association Award nomination, the National Eye Institute’s Scientific Director’s Award, and the Association for Research in Vision and Ophthalmology’s Merck Innovative Ophthalmology Research Award. He also founded and served as director of the Student Sight Savers Program, a program that provides vision screening services to low-income residents of Baltimore, and helps them obtain access to clinical ophthalmological care.
Presently, Dr. Johnson is interested in the neurobiological processes that lead to retinal ganglion cell death and dysfunction in glaucoma and other optic neuropathies. In particular, he seeks to better understand the molecular mechanisms underlying axonal degeneration, dendrite retraction and afferent synapse loss, and cell body death in glaucoma. His goal is to utilize knowledge of these processes to develop targeted neuroprotective strategies to slow or halt RGC death and preserve vision for patients with glaucoma. He is also leading new investigations into the use of stem cell transplantation to achieve retinal ganglion cell placement, as a potential regenerative treatment for optic nerve disease, with a focus on anatomic incorporation of cell grafts, neurite growth and synapse formation, and electrophysiological retinal circuit integration.
Artificial intelligence; it’s everywhere! Our homes, our cars, our schools and work. So where, if ever, does it stop? And how close to ourselves can our devices reasonably get? For this video, Unveiled uncovers plans to use human brain implants to improve the performance of our brains! What do you think? Are neural implants a good thing, or a bad thing?
This is Unveiled, giving you incredible answers to extraordinary questions!
A new theory suggests that mutations have few straightforward ways to establish themselves in cells and cause tumors.
For many researchers, the road to cancer prevention is long and difficult, but a recent study by Rice University scientists suggests that there may be shortcuts.
A theoretical framework is being developed by Rice scientist Anatoly Kolomeisky, postdoctoral researcher Hamid Teimouri, and research assistant Cade Spaulding that will explain how cancers brought on by several genetic mutations might be more readily recognized and perhaps prevented.
Amazon showed off a “fully autonomous mobile robot” called Proteus that can move carts around its warehouses, and even interact with humans, all on its own. The company also has other robots it’s working on.
Swedish truck manufacturer Volvo Trucks has unveiled a hydrogen fuel cell truck which the company claims will have a range of up to 1,000 kilometres and a refuelling time of less than 15 minutes.
The hydrogen fuel cell truck will join other zero-emission truck options already on offer, battery-electric trucks and trucks that run on renewable fuels such as biogas.
“We have been developing this technology for some years now, and it feels great to see the first trucks successfully running on the test track,” said Roger Alm, president of Volvo Trucks.
