You might call it a giant leap for 3D bioprinting: Human heart cells have been 3D printed on the International Space Station (ISS) and are making their way back to Earth this week inside a SpaceX capsule. The 3D BioFabrication Facility (BFF) was developed by Techshot Inc., a commercial operator of microgravity research and manufacturing equipment, in partnership with nScrypt, a manufacturer of industrial 3D bioprinters and electronics printers.

“Our BFF has the potential to transform human healthcare in ways not previously possible,” said Techshot President and CEO John Vellinger.” We’re laying the foundation for an entire industry in space.”

If you’re wondering why they don’t just print the cells here on Earth, the answer is gravity. When attempting to print with soft, easily flowing biomaterials on Earth, the tissues collapse under their own weight, resulting in little more than a puddle, explained Techshot in a press release. “But when these same materials are used in the microgravity environment of space, the 3D-printed structures maintain their shapes.” The bio-ink used in the space station, consequently, did not contain the scaffolding materials or thickening agents normally required to resist the Earth’s gravitational pull.

The information-processing capabilities of the brain are often reported to reside in the trillions of connections that wire its neurons together. But over the past few decades, mounting research has quietly shifted some of the attention to individual neurons, which seem to shoulder much more computational responsibility than once seemed imaginable.

The latest in a long line of evidence comes from scientists’ discovery of a new type of electrical signal in the upper layers of the human cortex. Laboratory and modeling studies have already shown that tiny compartments in the dendritic arms of cortical neurons can each perform complicated operations in mathematical logic. But now it seems that individual dendritic compartments can also perform a particular computation — “exclusive OR” — that mathematical theorists had previously categorized as unsolvable by single-neuron systems.

“I believe that we’re just scratching the surface of what these neurons are really doing,” said Albert Gidon, a postdoctoral fellow at Humboldt University of Berlin and the first author of the paper that presented these findings in Science earlier this month.

Thousands of Australians appear to believe lasers and exploding smart meters are being used to start our bushfires to make way for a new train network.

A Storyful investigation with news.com.au has found the conspiracy theory has spread far and wide on social media — with “directed-energy weapons” (DEWs) posts being shared tens of thousands of times in the past few weeks.

Those who believe the theory say the bushfires in this unprecedented season are being started using weapons which harness the focused power of technology such as lasers or microwaves.

FSJs (Ferroelectric Semiconductor Junction) in neuromorphic chips.

Engineers at Purdue University and at Georgia Tech have constructed the first devices from a new kind of two-dimensional material that combines memory-retaining properties and semiconductor properties. The engineers used a newly discovered ferroelectric semiconductor, alpha indium selenide, in two applications: as the basis of a type of transistor that stores memory as the amount of amplification it produces; and in a two-terminal device that could act as a component in future brain-inspired computers. The latter device was unveiled last month at the IEEE International Electron Devices Meeting in San Francisco.

Ferroelectric materials become polarized in an electric field and retain that polarization even after the field has been removed. Ferroelectric RAM cells in commercial memory chips use the former ability to store data in a capacitor-like structure. Recently, researchers have been trying to coax more tricks from these ferroelectric materials by bringing them into the transistor structure itself or by building other types of devices from them.

Maintaining five healthy habits—eating a healthy diet, exercising regularly, keeping a healthy body weight, not drinking too much alcohol, and not smoking—at middle-age may increase years lived free of type 2 diabetes, cardiovascular disease, and cancer, according to a new study led by Harvard T.H. Chan School of Public Health.

People who practice healthy habits at age 50 lived more years free of chronic diseases compared to those who did not practice any of these habits. Women who practiced all five habits gained about ten years of disease-free life, and men who did so gained about eight years. A healthy lifestyle not only improves lifespan (overall life expectancy) but also healthspan (healthy or disease-free life expectancy).

The National Bio and Agro-Defense Facility (NBAF) will be a state-of-the-art biocontainment laboratory for the study of diseases that threaten both America’s animal agricultural industry and public health. DHS S&T is building the facility to standards that fulfill the mission needs of the U.S. Department of Agriculture (USDA) which will own, manage and operate (PDF, 16 pgs., 165 KB) the NBAF once construction and commissioning activities are complete. The NBAF will strengthen our nation’s ability to conduct research, develop vaccines, diagnose emerging diseases, and train veterinarians. DHS S&T will leverage the facility as a national asset to fulfill homeland security mission needs.

TOPEKA, Kan. (KSNT) – All committee meetings were canceled Tuesday afternoon and all Kansas House members were called to the Kansas Air National Guard for a meeting with the U.S. Department of Homeland Security.

Kansas Deputy Attorney General Jay Scott Emler sent a letter to Speaker Ron Ryckman Tuesday saying that the DHS briefing should be given in a closed caucus.
