The coordinated activity of neural populations underlies myriad brain functions. Manipulating this activity using brain stimulation techniques has great potential for scientific and clinical applications, as they causally influence the nervous system. To improve the accuracy by which one can manipulate neural activity, it is important to (1) take into account the pre-stimulation brain state, which can influence the brain's response to stimulation, and (2) adaptively update stimulation parameters over time to compensate for changes in the brain's response to stimulation. In this work, we propose Online MicroStimulation Optimization (OMiSO), a brain stimulation framework that leverages brain state information to find stimulation parameters that can drive neural population activity toward specified states. OMiSO includes two key advances: i) training a stimulation-response model that leverages the pre-stimulation brain state, and inverting this model to choose the stimulation parameters, and ii) updating this inverse model online using newly-observed responses to stimulation. We tested OMiSO using intracortical microstimulation with a "Utah" array and found that it outperformed competing methods that do not incorporate these advances. Taken together, OMiSO provides greater accuracy in achieving specified activity states, thereby advancing neuromodulation technologies for understanding the brain and for treating brain disorders.

A.1 Behavioral Task A male nonhuman primate (NHP, Macaca mulatta), Monkey N (age 7 at the beginning of the dataset, age 11 at the end), was trained to perform a trial-based, two degree-of-freedom (DOF) dexterous finger movement task, shown in Figure 1. During all sessions, Monkey N sat in a primate chair (Crist Instruments, Hagerstown, MA) in a shielded chamber, with his arms fixed at his sides and flexed 90 degrees at the elbow, resting on a table. The left hand was positioned securely in a manipulandum, which used bend sensors (FS-L-0073-103-ST, Spectra Symbol, Salt Lake City, UT) to measure the flexion of two finger groups, index (IDX) and middle-ring-small (MRS). At the beginning of each experimental session (and as needed throughout a session), these flexion sensors were calibrated such that a reading of 1 indicated full flexion of a finger group and a reading of 0 indicated full extension. These readings were used to update the positions of the corresponding finger groups of a virtual hand presented on a screen in front of Monkey N. Bend sensor values were sampled at 1000 Hz. Updates to the virtual hand were limited to the refresh rate of the monitor (120 Hz). The task itself involved trial-based target acquisitions. At the beginning of each trial, two color-coded spherical targets, one for each DOF, were placed on the screen, covering 15% of the full arc of motion (see Figure 1A). Monkey N then acquired the targets by moving his fingers to the correct positions and holding his position for 750 ms.

Data center investors point to competition with China as reason to speed up U.S. AI infrastructure production amid cancellations and regulatory scrutiny across the country.

To enhance surface property analysis for irrigation mapping, we compute a suite of spectral indices capturing vegetation health, water presence, and soil conditions12. Common vegetation indices such as NDVI, GNDVI, and CIgreen quantify canopy vigor and chlorophyll content, while EVI, SAVI, and MSAVI account for atmospheric and soil background effects [44, 68, 28].

The world's largest data centre (62sq miles) has been approved in Utah, but there is growing opposition towards the project. At twice the size of Manhattan with promises to create thousands of jobs, we look at the bi partisan opposition against it. In this episode, Justin and Anthony discuss the enormous buildings being built across rural America, to house the huge amounts of data that A.I companies work with. Tech bosses say the centres are essential to the growth of Artificial Intelligence.

With a competitive price, winning design, and better performance than the R1, Rivian could be set to break into the big leagues. Just make sure you get the right model with the right tech. For years, Rivian made one argument: Serious all-electric adventure vehicles had to cost serious money. The R1S, still one of the more capable off-roaders on any surface, starts at $75,900. The R2 is Rivian's answer to its own problem.

Drones disrupted firefighting flights over Utah wildfires and probed military bases, highlighting urgent need for unified national drone defense and clearer airspace rules.

Petitioners react as the Box Elder county commission announces approval of a large datacenter on 4 May 2026 in Tremonton, Utah. Petitioners react as the Box Elder county commission announces approval of a large datacenter on 4 May 2026 in Tremonton, Utah. 'Irresponsible': backlash as Utah approves datacenter twice the size of Manhattan A plan to create one of the world's largest datacenters, a gargantuan project spanning an area more than twice the size of Manhattan, has provoked a furious public backlash in Utah amid concerns over its vast energy use and impact upon the state's stressed water supplies. The Stratos artificial intelligence datacenter footprint will cover more than 40,000 acres (62 sq miles) over three sites in Box Elder county in north-western Utah. The facility will require about 9GW of power, which is more than the entire state of Utah currently consumes, and suck up a significant amount of water in an area that has been hit by severe drought in recent years.
