With the help of extensive data from intensive care units of various hospitals, an artificial intelligence was developed that provides suggestions for the treatment of people who require intensive care due to sepsis. Analyses show that artificial intelligence already surpasses the quality of human decisions. However, it is now important to also discuss the legal aspects of such methods.

Researchers have developed a robot, called ReMotion, that occupies physical space on a remote user's behalf, automatically mirroring the user's movements in real time and conveying key body language that is lost in standard virtual environments.

Listening to music could reduce the dizziness, nausea and headaches virtual reality users might experience after using digital devices, research suggests. Cybersickness -- a type of motion sickness from virtual reality experiences such as computer games -- significantly reduces when joyful music is part of the immersive experience, the study found. The intensity of the nausea-related symptoms of cybersickness was also found to substantially decrease with both joyful and calming music.

The first statistically realistic roadway simulation has now been developed. While it currently represents a particularly perilous roundabout, future work will expand it to include other driving situations for testing autonomous vehicle software.

The way our senses adjust while playing high-intensity virtual reality games plays a critical role in understanding why some people experience severe cybersickness and others don't.

Researchers develop an early warning system that combines acoustic technology with AI to immediately classify earthquakes and determine potential tsunami risk. They propose using underwater microphones, called hydrophones, to measure the acoustic radiation produced by the earthquake, which carries information about the tectonic event and travels significantly faster than tsunami waves. The computational model triangulates the source of the earthquake and AI algorithms classify its slip type and magnitude. It then calculates important properties like effective length and width, uplift speed, and duration, which dictate the size of the tsunami.

A new smart material is activated by both heat and electricity, making it the first ever to respond to two different stimuli.

Faults in the Ridgecrest, California area were very sensitive to solid earth tidal stresses in the year and a half before the July 2019 Ridgecrest earthquake sequence.

Tsunami deposits identified in a coastal mangrove pond in Northwest Puerto Rico could have come from a megathrust earthquake at the Puerto Rico Trench that occurred between 1470 and 1530, according to new research.

Using remote sensing, geophysicists have documented the massive Feb. 6 quake that killed more than 50,000 people in Eastern Turkey and toppled more than 100,000 buildings. Alarmingly, researchers found that a section of the fault remains unbroken and locked -- a sign that the plates there may, when friction intensifies, generate another magnitude 6.8 earthquake when it finally gives way.

Even though most of the economic losses are concentrated in California and along the West Coast due to that region's high seismic hazard levels, significant population, and building exposure, earthquake risk is spread throughout the country. For example, there is a combined $3.1 billion per year in projected losses across the central U.S., Rocky Mountain region, Alaska, Hawaii, Puerto Rico and the Virgin Islands.

5G signals known as millimeter-wave carry enormous amounts of information but are very easy to block. A new device helps these signals get around obstacles posed by walls, furniture and people.

Earthquakes and volcanism occur as a result of plate tectonics. The movement of tectonic plates themselves is largely driven by the process known as subduction. The question of how new active subduction zones come into being, however, is still under debate. An example of this is the volcanic Lesser Antilles arc in the Caribbean. A research team recently developed models that simulated the occurrences in the Caribbean region during the Cretaceous, when a subduction event in the Eastern Pacific led to the formation of a new subduction zone in the Atlantic. The computer simulations show how the collision of the old Caribbean plateau with the Greater Antilles arc contributed to the creation of this new Atlantic subduction zone. Some 86 million years ago, the triggered processes subsequently resulted in a major mantle flow and thus to the development of the Caribbean large igneous province.

Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.

Researchers have developed a new way to create dynamic ultrahigh-density 3D holographic projections. They now describe their new approach, called three-dimensional scattering-assisted dynamic holography (3D-SDH). They show that it can achieve a depth resolution more than three orders of magnitude greater than state-of-the-art methods for multiplane holographic projection.

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet. This finding could prove beneficial in the search for life on other planets.

The push toward truly autonomous vehicles has been hindered by the cost and time associated with safety testing, but a new system shows that artificial intelligence can reduce the testing miles required by 99.99%.

Research using a quantum computer as the physical platform for quantum experiments has found a way to design and characterize tailor-made magnetic objects using quantum bits, or qubits. That opens up a new approach to develop new materials and robust quantum computing.
