What Does Your Gaze Reveal About You? On the Privacy Implications of Eye Tracking. With reference to published research, filed patents, and existing commercial products, this section presents and categorizes personal information that can be inferred from eye tracking data.
As a basis for potential inferences, eye tracking devices can record a large variety of gaze parameters. Some of the most commonly measured eye movements are fixations, saccades, and smooth pursuit eye movements . During a fixation, the eyes are relatively stable and focused on a specific position, allowing for information to be acquired and processed. Saccades are rapid eye movements from one fixation point to another, lasting 30 to 80 ms . Smooth pursuit movements are performed when eyes are closely following a moving visual target. 2.1 Biometric Identification Due to differences in physical oculomotor structure and brain functioning, certain gaze characteristics are unique for every individual, similar to fingerprints, and can thus be exploited for biometric identification [9, 74, 76]. Covid Tip Sheet: Scientists Use Ultraviolet Light to Disinfect CT Scanners.
The COVID-19 pandemic has sparked heightened awareness of cleaning and disinfecting procedures in many industries.
Health care facilities have long been familiar with protocols for disinfecting tools and equipment, and now, scientists are studying methods to improve these procedures, making them safer and more efficient for patients and health care workers. At Johns Hopkins, biomedical engineer Jeff Siewerdsen and medical physicist Mahadevappa Mahesh are investigating the use of UV light to disinfect the inner bore of CT scanning machines, a cramped space that is exposed to exhaled particles from patients and is difficult to reach by manually wiping it down. The UV light being studied is not the typical beam of sunshine that falls to the earth. Those rays are mostly UVA rays, which tend to cause skin cancer and other problems.

No eyes? No problem. Worms still avoid the blues. Worms don’t like the blues.
At least not the blue-tinged toxic bacteria that are common in the environments where they live. But how does a bacteria-foraging worm — without eyes, photoreceptors, or the opsin genes that help animals perceive color — know to avoid the toxic, blue-reflecting bacterium known as Pseudomonas aeruginosa? Until recently, Yale’s Michael Nitabach thought worms must recognize distinct chemosensory odors emitted by this bacterium. Four causes for ‘Zoom fatigue’ and their solutions. Even as more people are logging onto popular video chat platforms to connect with colleagues, family and friends during the COVID-19 pandemic, Stanford researchers have a warning for you: Those video calls are likely tiring you out.
Professor Jeremy Bailenson examined the psychological consequences of spending hours per day on Zoom and other popular video chat platforms. (Image credit: Getty Images) Prompted by the recent boom in videoconferencing, communication Professor Jeremy Bailenson, founding director of the Stanford Virtual Human Interaction Lab (VHIL), examined the psychological consequences of spending hours per day on these platforms. Edible holograms could someday decorate foods. “Direct Printing of Nanostructured Holograms on Consumable Substrates”ACS Nano Holograms are everywhere, from driver’s licenses to credit cards to product packaging.
And now, edible holograms could someday enhance foods. Researchers reporting in ACS Nano have developed a laser-based method to print nanostructured holograms on dried corn syrup films. The edible holograms could also be used to ensure food safety, label a product or indicate sugar content, the researchers say. Most holograms are imprinted with lasers onto metal surfaces, such as aluminum, but the materials aren’t edible. To develop their method, the researchers made a solution of corn syrup, vanilla and water and dried it into a thin film.

A ‘FROC’ can both transmit and reflect the same color simultaneously, a breakthrough in optical coating.
For more than a century, optical coatings have been used to better reflect certain wavelengths of light from lenses and other devices or, conversely, to better transmit certain wavelengths through them. For example, the coatings on tinted eyeglasses reflect, or “block out,” harmful blue light and ultraviolet rays. But until now, no optical coating had ever been developed that could simultaneously reflect and transmit the same wavelength, or color. In a paper in Nature Nanotechnology, researchers at the University of Rochester and Case Western Reserve University describe a new class of optical coatings, so-called Fano Resonance Optical Coatings (FROCs), that can be used on filters to reflect and transmit colors of remarkable purity.
In addition, the coating can be made to fully reflect only a very narrow wavelength range. Remyelinating drug could improve vision in patients with multiple sclerosis. A team led by a biomedical scientist at the University of California, Riverside, reports a drug — an estrogen receptor ligand called indazole chloride (IndCl) — has the potential to improve vision in patients with multiple sclerosis, or MS.
The study, performed on mice induced with a model of MS and the first to investigate IndCl’s effect on the pathology and function of the complete afferent visual pathway, is published in Brain Pathology. The afferent visual pathway includes the eyes, optic nerve, and all brain structures responsible for receiving, transmitting, and processing visual information. In MS, a disease in which the immune system “demyelinates” or eats away at the protective covering of nerves, the initial period of inflammation and demyelination often damages the optic nerve and other parts of the visual system first. Investigadores buscan identificar problemas de miopía mediante el uso de algoritmos de inteligencia artificial. A Rift in the Retina May Help Repair the Optic Nerve.
“The idea of restoring vision to someone who has lost it from optic nerve disease has been considered science fiction for decades.
But in the last five years, stem cell biology has reached a point where it’s feasible,” says Thomas Johnson, M.D., Ph.D., assistant professor of ophthalmology at the Wilmer Eye Institute at the Johns Hopkins University School of Medicine. The research was published Jan. 12 in the journal Stem Cell Reports. A human eye has more than 1 million small nerve cells, called retinal ganglion cells, that transmit signals from light-collecting cells called photoreceptors in the back of the eye to the brain.
Retinal ganglion cells send out long arms, or axons, that bundle together with other retinal ganglion cell projections, forming the optic nerve that leads to the brain. When the eye is subjected to high pressure, as occurs in glaucoma, it damages and eventually kills retinal ganglion cells. Development of the first biohybrid artificial retina built with silk fibroin and retinal cells. "The biohybrid retina is a cell therapy for the reconstruction of the damaged retina by implanting healthy cells in the patient's eye," says Fivos Panetsos, director of the Neuro-computation and Neuro-robotics Group of the UCM and member of the Institute of Health Research of the Hospital Clínico San Carlos de Madrid (IdISSC).
The cells of the artificial retina adhere to very thin silk fibroin biofilms - a biomaterial 100% biocompatible with human tissue - and covered by a gel which protects them during eye surgery and allows them to survive during the time they need to get integrated with thesurrounding tissue after transplantation. "The transplanted retina also contains mesenchymal cells that function as producers of neuroprotective and neuroreparative molecules and facilitate functional integration between implanted and patient cells", adds UCM's researcher and director of the study, published in the Journal of Neural Engineering . Gene therapy injection in one eye surprises scientists by improving vision in both.
In a landmark phase 3 clinical trial, the international team, coordinated by Dr Patrick Yu-Wai-Man from the University of Cambridge and Dr José-Alain Sahel from the University of Pittsburgh and Institut de la Vision, Paris, successfully treated 37 patients suffering from Leber hereditary optic neuropathy (LHON). Subject to further trials, the treatment could help thousands of people across the world to regain and retain some of their sight. The study, published today in the journal Science Translational Medicine, indicates that 78% of treated patients experienced significant visual improvement in both eyes. It suggests that the improvement in vision in untreated eyes could be due to the transfer of viral vector DNA from the injected eye. LHON affects a specific type of retinal cells, known as retinal ganglion cells, causing optic nerve degeneration and rapidly worsening vision in both eyes.
Dr Yu-Wai-Man said: “Saving sight with gene therapy is now a reality. Notes Funding Reference. Introducing EyeQue VisionCheck 2 – the World’s Most Powerful Do-It-Yourself Smartphone Vision Test.

As we move away from fossil fuels and shift to renewable energy to tackle climate change, the need for new ways to capture and store energy becomes increasingly important.
Lancaster University researchers studying a crystalline material have discovered it has properties that allow it to capture energy from the sun. The energy can be stored for several months at room temperature, and it can be released on demand in the form of heat. With further development, these kinds of materials could offer exciting potential as a way of capturing solar energy during the summer months, and storing it for use in winter - where less solar energy is available. Scientists develop new gene therapy for eye disease - Trinity News and Events. Scientists from Trinity have developed a new gene therapy approach that offers promise for one day treating an eye disease that leads to a progressive loss of vision and affects thousands of people across the globe. The study, which involved a collaboration with clinical teams in the Royal Victoria Eye and Ear Hospital and the Mater Hospital, also has implications for a much wider suite of neurological disorders associated with ageing.
The scientists publish their results today in leading journal, Frontiers in Neuroscience. Institute - Contact Lenses For Diagnostic and Therapeutic Use. (LOS ANGELES) – Human bodily fluids and secretions contain molecules known as biomarkers that contain a wealth of information about the body’s health and the presence of disease. Among secretions such as tears, sweat and saliva, tears are considered the best source of biomarkers, with concentrations similar to those found in blood. Tears are also sterile, readily available and less susceptible to the damaging effects of temperature change, evaporation and secretion rate. Useful and measurable biomarkers found in tears include sodium ions, which are useful indicators of dry-eye disease, and glucose molecules, an early diagnostic tool for diabetes.

Scientists Use Nanoparticle-Delivered Gene Therapy to Inhibit Blinding Eye Disease in Rodents. The research, described July 3 in Science Advances, provides evidence of the potential value of nanoparticle-delivered gene therapy to treat wet age-related macular degeneration — an eye disease characterized by abnormal blood vessel growth that damages the light-sensitive tissue in the back of the eye — as well as more rare, inherited blinding diseases of the retina. Many gene therapy approaches depend on viral vectors, which use a virus’s natural ability to carry genetic material into cells.
However, viruses create an immune response, which prevents repeat dosing, and the most commonly used one for ocular gene therapy cannot carry large genes. “Some of the most prevalent inherited retinal degenerations are due to mutations in large genes that simply cannot fit into the most commonly used viral vector,” says Peter Campochiaro, M.D., the Eccles Professor of Ophthalmology at the Johns Hopkins University School of Medicine, and a member of the Johns Hopkins Medicine Wilmer Eye Institute.
