How different text display patterns affect cybersickness in augmented reality

Cybersickness significantly impacts AR user experience, especially in reading tasks. Research with 40 participants revealed that text speed, movement, and color contribute to cybersickness, which impairs search ability. Gender affects cybersickness onset at lower levels, while past AR experience influences its intensity.

Handheld ultrasensitive fentanyl sensor can distinguish between opioids

A handheld electrochemical sensor using carbon nanotubes and gold nanoparticles detects fentanyl at femtomolar levels and distinguishes between opioids. Developed by University of Pittsburgh researchers, it addresses the need for rapid, accurate fentanyl detection in adulterated drugs.

The tunable coupling of two distant superconducting spin qubits

Quantum computers use qubits, which can simultaneously be 0 and 1, to potentially surpass classical computing in complex tasks. Researchers at Delft University of Technology demonstrated strong, tunable coupling between distant Andreev spin qubits, advancing the realization of two-qubit gates.

Mysterious element promethium finally reveals its chemical properties

A new water-formed compound of the rare element promethium reveals its properties for the first time. Despite promethium's extreme radioactivity and instability, researchers at Oak Ridge National Laboratory successfully studied its chemistry by mitigating radioactive damage and avoiding crystal structure interference.

Second human case of bird flu linked to cows found—via text messages

A Michigan dairy farm worker tested positive for H5 bird flu, the second human case linked to the H5N1 outbreak among US dairy cows. The worker had a mild eye infection and recovered. The infection was detected through an active CDC surveillance system.

Adhesive coatings can prevent scarring around medical implants

MIT engineers developed a hydrogel adhesive that prevents fibrosis by coating medical implants, such as pacemakers. This coating binds devices to tissue, preventing immune responses and scar tissue buildup that can interfere with device function and necessitate removal.

Micro-tornadoes help transport nutrients within egg cells

US scientists simulated nutrient transport in maturing egg cells, using microtubules, motors, and fluid. They discovered tornado-like vortex flows enable rapid mixing and transport of critical components for egg cell development, enhancing our understanding of cellular nourishment in organism growth and development.

Higher intake of ultra-processed foods linked to increased risk of stroke and cognitive decline

A study in Neurology® found that consuming more ultra-processed foods, such as soft drinks, chips, and cookies, is associated with a higher risk of memory and thinking problems and stroke. The study shows an association, not causation.

SpaceX launches 23 Starlink satellites on 2nd leg of spaceflight doubleheader

SpaceX launched another batch of its Starlink internet satellites from Florida on Wednesday night (May 22), the second mission in less than 24 hours for the company.

NASA’s Compact Infrared Cameras Enable New Science

A new high-resolution infrared camera with lightweight filters can analyze sunlight reflected off Earth’s atmosphere, enhance forest fire warnings, and identify other planets' molecular composition. Developed at NASA's Goddard Space Flight Center, it features compact, adaptable strained-layer superlattice sensors.
