Induce lucid dreams on demand to unravel the mystery of consciousness.
The combination of ultrasound and machine learning models (created using EEG & fMRI data) allows us to detect when dreamers are in REM to induce and stabilize lucid dreams.
A team of George Mason University scientists has received a federal grant of more than $13 million to work with the Department of the Navy to study and better understand increased solar activity that could potentially cause an “internet apocalypse” disrupting all electronic communications on Earth, including satellite communications.
Research from the grant, which will total $13.6 million in expenditures over five years, will be done in collaboration with the Naval Research Laboratory (NRL), and will include state-of-the-art data mining, analysis, and scientific modeling, among other endeavors, led by Mason faculty, students and staff. Under the terms of the contract, Mason provides scientific support for a broad range of astronomy-related activities that are of interest to the U.S. Navy and the nation at large.
“The main focus is on solar activity and the way it can impact systems on Earth,” said principal investigator Peter A. Becker, a professor in the Department of Physics and Astronomy within the College of Science. “This is especially important to the Navy—and more broadly the Department of Defense—because high-energy outbursts from the sun can have a strong negative impact on earthly radio and internet communications. And they can also have a detrimental effect on navigation systems and energy grids on Earth.”
Scientists using NASA’s James Webb Space Telescope just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, Webb confirmed a physical process involving the drifting of ice-coated solids from the outer regions of the disk into the rocky-planet zone.
Theories have long proposed that icy pebbles forming in the cold, outer regions of protoplanetary disks — the same area where comets originate in our solar system — should be the fundamental seeds of planet formation. The main requirement of these theories is that pebbles should drift inward toward the star due to friction in the gaseous disk, delivering both solids and water to planets.
A fundamental prediction of this theory is that as icy pebbles enter into the warmer region within the “snowline” — where ice transitions to vapor — they should release large amounts of cold water vapor. This is exactly what Webb observed.
Optimal culture conditions for cynomolgus monkey naive embryonic stem cells and improved procedures for chimeric embryo culture were developed to allow for high (20%–90%) donor cell contribution to chimeric monkeys.
Alaskans and visitors may be able to see an artificial airglow in the sky created by the High-frequency Active Auroral Research Program during a four-day research campaign that starts Saturday.
Scientists from the University of Alaska Fairbanks, Cornell University, University of Colorado Denver, University of Florida and Georgia Institute of Technology will conduct a variety of experiments at the UAF-operated research site.
The experiments will focus on the ionosphere, the region of the atmosphere between about 30 and 350 miles above the Earth’s surface.
Adoptive cell therapy has emerged as a promising alternative treatment for hematological and solid cancers, with CAR-T therapy standing out as a prominent avenue. In this approach, T cells are genetically engineered with chimeric antigen receptors (CARs) to enhance their targeting capabilities1–2. The outcome of CAR-T cell therapy hinges on a complex interplay of phenotype, activation, and functional profiling of these engineered cells. Immunophenotypic characterization of CAR-T cells assumes a pivotal role in ensuring treatment quality and facilitating continuous monitoring of treatment response1. In the process of immunophenotyping, engineered T cells are separated based on their markers to characterize the composition of the cell population within the sample. The strategic identification and isolation of specific CAR-T cell subsets is essential in augmenting therapy responses2.
Deciphering Cellular Composition, Defining CAR-T Therapy Efficacy
Immunophenotyping is a pivotal technique that combines specific antibodies with fluorescent compounds to reveal specific protein expression in cell populations to identify categorize the tagged cells. Immunophenotyping leverages the differences in surface markers among T cells, reflecting their differentiation, activation, and memory status2. These markers provide insights into immune cell development, function, proliferation potential, and long-term viability. The distinct surface marker profiles closely correlate with the efficacy of CAR-T cell therapy3. Essential markers for immunophenotypic analysis, including CD3, CD4, CD8, CD45RA, CD34R0, CCR7, CD27, and CD95, are presented in Table 1.
“Dinkinesh really did live up to its name; this is marvelous,” said Hal Levison, referring to the meaning of Dinkinesh in the Amharic language, “marvelous.” Levison is principal investigator for Lucy from the Boulder, Colorado, branch of the San-Antonio-based Southwest Research Institute. “When Lucy was originally selected for flight, we planned to fly by seven asteroids. With the addition of Dinkinesh, two Trojan moons, and now this satellite, we’ve turned it up to 11.”
In the weeks prior to the spacecraft’s encounter with Dinkinesh, the Lucy team had wondered if Dinkinesh might be a binary system, given how Lucy’s instruments were seeing the asteroid’s brightness changing with time. The first images from the encounter removed all doubt. Dinkinesh is a close binary. From a preliminary analysis of the first available images, the team estimates that the larger body is approximately 0.5 miles (790 m) at its widest, while the smaller is about 0.15 miles (220 m) in size.
This encounter primarily served as an in-flight test of the spacecraft, specifically focusing on testing the system that allows Lucy to autonomously track an asteroid as it flies past at 10,000 mph, referred to as the terminal tracking system.
NASA’s Lucy Spacecraft took images of asteroid Dinkinesh, discovering that the asteroid has the first-ever contact binary pair orbiting the asteroid.
The resolution of a major discrepancy between theory and experiment for strontium atomic clocks could help improve the precision of these timekeepers.
