“Our findings represent a dramatic divergence from the current dogma, which works primarily on the premise that neurotransmitters like serotonin and dopamine act solely through the activation of their membrane receptors in the brain to regulate brain cell activity,” says Ian Maze, PhD, Assistant Professor of Neuroscience, and Pharmacological Sciences, at the Icahn School of Medicine at Mount Sinai, and senior author of the paper. “We found actions of these brain chemicals that are independent of neurotransmission but critically important to their overall signaling, suggesting that our current understanding of these molecules is incomplete and requires further investigation.”

Findings could fundamentally change how scientists interpret the biological activities of serotonin.

The Made In Space Archinaut program has accomplished another exciting milestone. During recent testing at Northrop Grumman’s Space Park facilities in Redondo Beach, California, we successfully operated Archinaut’s core additive manufacturing and robotic assembly technology suite in a space-like environment. These operations took place in a thermal vacuum (TVAC) chamber, simulating the extreme temperature and vacuum pressure of what a satellite in Low Earth Orbit (LEO) would be exposed to. The completion of this ground-based testing raises the technology readiness level (TRL) of the Archinaut platform and demonstrates that core Archinaut technologies are now prepared to operate in space.

The Archinaut platform looks to provide mission critical, space-optimized structures on orbit that would otherwise be too large to launch, using on-demand, adaptable manufacturing. With the marriage of additive manufacturing and robotic assembly, Archinaut enabled structures can range from:

Meet the UDrone: a clever quadcopter that you can control with your thoughts or simple hand gestures. You can activate its camera by blinking or making the “V” hand gesture. The drone has subject & facial tracking, 3 adjustable speed settings, and an auto-flight control system.

The UDrone is easy to use: simply imagine it taking off and once you are concentrated enough, the drone will take off. It has mobile app control too.

Sports car maker Bugatti (Molsheim, France) used SLM Solutions’ (Lübeck, Germany) metal additive manufacturing technology to produce automotive components. The components were manufactured in the aerospace alloy Ti₆Al₄V in cooperation with the Fraunhofer Research Institution for Additive Manufacturing Technologies (Fraunhofer IAPT; Hamburg, Germany) and Bionic Production (Lüneburg, Germany) on a SLM 500 selective laser melting system featuring four 400 W lasers.

A caliper test showed that additively produced metal components can cope with extreme strength, stiffness, and temperature requirements at speeds of over 375 km/h with a braking force of 1.35 g and brake disc temperatures up to 1100°C, says Frank Götzke, Head of New Technologies at Bugatti. The test also showed that a tensile strength of 1250 N/mm and a material density over 99.7% was achieved.

A team of researchers from the University of St Andrews (St Andrews, Scotland) has achieved a breakthrough in the measurement of lasers that they say could revolutionize the future of fiber-optic communications. They also say the wavelength meter (or wavemeter) will boost optical and quantum sensing technology, enhance the performance of next-generation sensors, and expand the information-carrying capacity of fiber-optic networks.

A team of researchers from the University of St Andrews has achieved a breakthrough in the measurement of lasers which could revolutionise the future of fiber-optic communications.

The new research, published in Optics Letters (Wednesday 6 March), reveals the team of scientists has developed a low-cost and highly-sensitive device capable of measuring the wavelength of light with unprecedented accuracy.
