CAPE CANAVERAL, Fla — An unmanned U.S. military space plane landed early Saturday after spending a record 908 days in orbit for its sixth mission and conducting science experiments.
The solar-powered vehicle, which looks like a miniature space shuttle, landed at NASA’s Kennedy Space Center. Its previous mission lasted 780 days.
“Since the X-37B’s first launch in 2010, it has shattered records and provided our nation with an unrivaled capability to rapidly test and integrate new space technologies,” said Jim Chilton, a senior vice president for Boeing, its developer.
A Tohoku University researcher has increased the performance of a high-power electrodeless plasma thruster, moving us one step closer to deeper explorations into space.
Innovations in terrestrial transportation technologies, such as cars, trains, and aircraft, have driven historical technologies and industries so far; now, a similar breakthrough is occurring in space thanks to electric propulsion technology.
Electric propulsion is a technique utilizing electromagnetic fields to accelerate a propellant and to generate thrust that propels a spacecraft. Space agencies have pioneered electric propulsion technology as the future of space exploration.
Today we return to the Fermi Paradox to contemplate the notion of civilizations which neither expand outwards to colonize the galaxy nor go extinct, but exist as long-term, high-tech civilizations just on their own planet or solar system. To discuss the possible motives and reasoning we will look at the many arguments raised for and against space exploration.
First insights into engineering crystal growth by atomically precise metal nanoclusters have been achieved in a study performed by researchers in Singapore, Saudi Arabia and Finland. The work was published in Nature Chemistry.
Ordinary solid matter consists of atoms organized in a crystal lattice. The chemical character of the atoms and lattice symmetry define the properties of the matter, for instance, whether it is a metal, a semiconductor or and electric insulator. The lattice symmetry may be changed by ambient conditions such as temperature or high pressure, which can induce structural transitions and transform even an electric insulator to an electric conductor, that is, a metal.
Larger identical entities such as nanoparticles or atomically precise metal nanoclusters can also organize into a crystal lattice, to form so called meta-materials. However, information on how to engineer the growth of such materials from their building blocks has been scarce since the crystal growth is a typical self-assembling process.
In a multi-year research program coordinated by the two directors of. NeuroRestore—Grégoire Courtine, a neuroscience professor at EPFL, and Jocelyne Bloch, a neurosurgeon at Lausanne University Hospital (CHUV)—patients who had been paralyzed by a spinal cord injury and who underwent targeted epidural electrical stimulation of the area that controls leg movement were able to regain some motor function.
In the new study by. NeuroRestore scientists, appearing today in Nature, not only was the efficacy of this therapy demonstrated in nine patients, but the improved motor function was shown to last in patients after the neurorehabilitation process was completed and when the electrical stimulation was turned off. This suggested that the nerve fibers used for walking had reorganized. The scientists believe it was crucial to understand exactly how this neuronal reorganization occurs in order to develop more effective treatments and improve the lives of as many patients as possible.
Climate TRACE is a global non-profit coalition created to make meaningful climate action faster and easier by independently tracking greenhouse gas (GHG) emissions with unprecedented detail and speed.
They harness satellite imagery and other forms of remote sensing, artificial intelligence, and collective data science expertise to track human-caused GHG emissions with unprecedented detail and speed.
Climate TRACE’s emissions inventory is the world’s first comprehensive accounting of GHG emissions based primarily on direct, independent observation. Our innovative, open, and accessible approach relies on advances in technology to fill critical knowledge gaps for all decision makers that rely on the patchwork system of self-reporting that serves as the basis for most existing emissions inventories.
Google has removed two new malicious dropper apps that have been detected on the Play Store for Android, one of which posed as a lifestyle app and was caught distributing the Xenomorph banking malware.
“Xenomorph is a trojan that steals credentials from banking applications on users’ devices,” Zscaler ThreatLabz researchers Himanshu Sharma and Viral Gandhi said in an analysis published Thursday.
“It is also capable of intercepting users’ SMS messages and notifications, enabling it to steal one-time passwords and multi-factor authentication requests.”
