DoD must modernize infrastructure to support cutting-edge technology research

Posted by in category: military

The road to the next great scientific or technological advance starts with basic science and research. Basic research is central to the DoD’s long-term competitive strategy to create and maintain military superiority for the nation. The DoD has a long history of conducting and sponsoring basic research, focusing on understanding how and why things work at a fundamental scientific level.

Pentagon AI center shifts focus to joint warfighting operations

Posted by in categories: military, robotics/AI

The Pentagon’s artificial intelligence hub is shifting its focus to enabling joint warfighting operations, developing artificial intelligence tools that will be integrated into the Department of Defense’s Joint All-Domain Command and Control efforts.

“As we have matured, we are now devoting special focus on our joint warfighting operation and its mission initiative, which is focused on the priorities of the National Defense Strategy and its goal of preserving America’s military and technological advantages over our strategic competitors,” Nand Mulchandani, acting director of the Joint Artificial Intelligence Center, told reporters July 8. “The AI capabilities JAIC is developing as part of the joint warfighting operations mission initiative will use mature AI technology to create a decisive advantage for the American war fighter.”

Countdown to Mars: three daring missions take aim at the red planet

Posted by in categories: alien life, robotics/AI

Three times in the coming month or so, rockets will light their engines and set course for Mars. A trio of nations — the United States, China and the United Arab Emirates (UAE) — will be sending robotic emissaries to the red planet, hoping to start new chapters of exploration there.

Each mission is a pioneer in its own right. The United States is sending its fifth rover, NASA’s most capable ever, in the hope of finding evidence of past life on Mars and collecting a set of rocks that will one day be the first samples flown back to Earth. China aims to build on its lunar-exploration successes by taking one of its rovers to Mars for the first time. And the UAE will be launching an orbiter — the first interplanetary mission by any Arab nation — as a test of its young but ambitious space agency.

It is far from a given that all these missions will make it; Mars is notorious as a graveyard for failed spacecraft. But if they do, they will substantially rewrite scientific understanding of the planet. The two rovers are heading for parts of Mars that have never been explored(see ‘Landing sites’), and the UAE’s orbiter will track the changing Martian atmosphere.

Research advances understanding of how the brain focuses while ignoring distractions

Posted by in category: neuroscience

When trying to complete a task we are constantly bombarded by distracting stimuli. How does the brain filter out these distractions and enable us to focus on the task at hand? Psychologists at the University of California, Riverside, have made a discovery that could lead to an answer.

Experimenting on mice, they located the precise spot in the brain where distracting stimuli are blocked. The blocking disables the brain from processing these stimuli, which allows concentration on a particular task to proceed.

Edward Zagha, an assistant professor of psychology, and his team trained mice in a sensory detection task with target and distractor stimuli. The mice learned to respond to rapid stimuli in the target field and ignore identical stimuli in the opposite distractor field. The team used a novel imaging technique, which allows for high spatiotemporal resolution with a cortex-wide field of view, to find where in the brain the distractor stimuli are blocked, resulting in no further signal transmission within the cortex and, therefore, no triggering of a motor response.

Drugs, money and misleading evidence

Posted by in categories: biotech/medical, economics

Child psychiatrist Jon Jureidini and philosopher Leemon McHenry dispute the assumption that all approved drugs and medical devices are safe and effective. They warn that when clinical science is hitched to the pharmaceutical industry’s dash for profits, the scientific method is undermined by marketing spin and cherry-picking of data. They propose a solution inspired by philosopher of science Karl Popper: take drug testing out of the hands of manufacturers.”


It’s time to take trials out of the hands of pharmaceutical makers, argues the latest in a long line of books on corruption and the pharmaceutical industry.
