MIT researchers have uncovered two additional pathways in the brain’s striatum that modulate traditional movement control pathways by influencing dopamine production.

These pathways, connected to the brain’s striosomes, may play a crucial role in decisions with strong emotional components, potentially altering our understanding of how motivation and movement are interconnected.

In the human brain, movement is coordinated by a region called the striatum, which sends signals to motor neurons. These signals travel along two main pathways: one initiates movement (“go”), and the other inhibits it (“no-go”).

A researcher has released a tool to bypass Google’s new App-Bound encryption cookie-theft defenses and extract saved credentials from the Chrome web browser.

The tool, named ‘Chrome-App-Bound-Encryption-Decryption,’ was released by cybersecurity researcher Alexander Hagenah after he noticed that others were already figuring out similar bypasses.

Although the tool achieves what multiple infostealer operations have already added to their malware, its public availability raises the risk for Chrome users who continue to store sensitive data in their browsers.

SAN FRANCISCO – Austrian space domain awareness startup iSEE Global established a U.S. subsidiary in Arlington, Virginia, led by former Kleos Space CEO Andy Bowyer.

The U.S. subsidiary of iSEE, which stands for Impact Space Expedition & Exploration Global Corp., seeks “proximity to key government and defense customers, like the U.S. Space Force, and major commercial clients,” Bowyer told SpaceNews by email. “The U.S. is the biggest and most influential SDA [space domain awareness] market.”

Having a U.S. subsidiary will help iSEE “navigate the complex regulatory requirements,” Bowyer said.

WASHINGTON — The Defense Department should step up support of commercial space companies to take advantage of capabilities that might otherwise be lost, a new report concludes.

That recommendation is among several in a study called Space Agenda 2025 released Oct. 24 by The Aerospace Corporation and its Center for Space Policy and Strategy (CSPS). The report is intended to provide advice to the next administration on key topics in civil, commercial and national security space.

In a briefing held in advance of the report’s release, Sam Wilson, systems director at CSPS, said the Defense Department is benefitting from growing commercial capabilities in areas like commercial remote sensing, much of which was fueled by a boom in private investment in space companies several years ago. Private investment has dropped significantly since a peak in 2021, though, and investors say access to capital remains difficult for space companies today, especially those trying to raise larger, later rounds.

During the time you read this article, something will happen in the sky that many scientists didn’t believe would happen until recently. NASA says that a magnetic doorway will open that will connect the Earth and the Sun, which are 150 million kilometers apart.

Hundreds of thousands of high-energy particles will pass through this gap until it closes, which will happen about the time you reach the bottom of the page.

Throughout their childhood, Earth and Theia lived in harmony but everything changed when gravitational disturbances attacked.

Scientists have proposed that two massive rock formations deep within Earth’s mantle, known as large low-shear velocity provinces (LLSVPs), might be the remnants of the protoplanet Theia, which collided with Earth 4.5 billion years ago to form the Moon. These formations, located beneath West Africa and the Pacific Ocean, are denser and chemically distinct from the surrounding mantle. Researchers are using new seismic and isotopic data to investigate whether Theia’s dense mantle survived and sank into Earth’s core. If true, this discovery could change our understanding of Earth’s structure and early history.

After reading the article, Marcus gained more than 529 upvotes with this comment: “I wonder where on Earth Theia hit. Is there even a way to determine this, or does the constant tectonic activity of Earth just erase that over time?” Don’t forget to share your thoughts about Theia and Earth’s mantle in the comment section below! For a long time, scientists have agreed that the Moon was formed after a protoplanet called Theia collided with the early Earth about 4.5 billion years ago. Now, a team of researchers has a new bold idea: The remains of Theia may be hidden in two massive layers of rock located deep within Earth’s mantle.

In a new study in Physical Review Letters, scientists have demonstrated a method to control artificial microswimmers using electric fields and fluid flow. These microscopic droplets could pave the way for targeted drug delivery and microrobotics.
