After a successfull simulated launch countdown on January 24, only a few tests remain for NASA’s big Moon rocket.

‘A watershed in furthering our understanding of these structures,’ researcher says.
An unprecedented new telescope image of the Milky Way galaxy’s turbulent center has revealed nearly 1,000 mysterious strands, inexplicably dangling in space.
Stretching up to 150 light years long, the one-dimensional strands (or filaments) are found in pairs and clusters, often stacked equally spaced, side by side like strings on a harp. Using observations at radio wavelengths, Northwestern University ’s Farhad Yusef-Zadeh discovered the highly organized, magnetic filaments in the early 1980s. The mystifying filaments, he found, comprise cosmic ray electrons gyrating the magnetic field at close to the speed of light. But their origin has remained an unsolved mystery ever since.
From creating a Zen garden on Mars to conducting sound experiments in the massive wind tunnel at NASA Ames, artist-adventurer Charles Lindsay’s work questions our understanding of time and consciousness. Lindsay is the founder of the SETI Institute’s Artist in Residence program and is now a visiting professor at Kyoto University of Arts. His sculptures, sound installations, and immersive environments, built from salvaged aerospace and bio-tech equipment, invite us to ponder ideas about technology, eco-systems, and semiotics.

“Somehow it’s converting magnetic energy to radio waves much more effectively than anything we’ve seen before,” team leader Dr. Hurley-Walker said.
Astronomers observed a mysterious object in the Milky Way that periodically releases a giant burst of energy. The object could be a magnetar, a type of neutron star.
Researchers have developed a new technique, called MonoCon, that improves the ability of artificial intelligence (AI) programs to identify three-dimensional (3D) objects, and how those objects relate to each other in space, using two-dimensional (2D) images. For example, the work would help the AI used in autonomous vehicles navigate in relation to other vehicles using the 2D images it receives from an onboard camera.
“We live in a 3D world, but when you take a picture, it records that world in a 2D image,” says Tianfu Wu, corresponding author of a paper on the work and an assistant professor of electrical and computer engineering at North Carolina State University.
“AI programs receive visual input from cameras. So if we want AI to interact with the world, we need to ensure that it is able to interpret what 2D images can tell it about 3D space. In this research, we are focused on one part of that challenge: how we can get AI to accurately recognize 3D objects—such as people or cars—in 2D images, and place those objects in space.”
New study discovers that a group of genes that play an essential role in building components of our cells can also impact human lifespan.
SOUTH BEND — The city council gave a unanimously positive recommendation Monday night for two tax abatements that could put South Bend at the epicenter of the hydroponic produce market in Indiana, and possibly the Midwest, for years to come.
JEM Farms South Bend plans to spend as much as $178 million on greenhouses and logistical equipment to grow tomatoes and strawberries throughout the year on land at Calvert Street and Renewable Drive, adjacent to the South Bend Ethanol Plant.
That facility would be located on land owned by Ceres Partners, the agricultural investment group located just south of the University of Notre Dame campus and the original investors in Pure Green Farms.
A team of researchers from the University of Arizona has proposed a “Lunar Ark” for preserving samples of 6.7 million Earth species in the event of a global crisis.
