3D printers emit microparticles that can embed in your lungs


If you have a 3D printer, you need to make sure it’s in a well-ventilated area–and maybe keep it out of a child’s room–because across the board, 3D printers release tiny, undetectable materials that could be toxic and embed themselves into your body permanently.

This advice comes courtesy of Georgia Tech professor Dr. Rodney Weber, who recently oversaw a landmark study on the emissions of 3D printers that was published in Aerosol Science and Technology.

Capacity Media | Infinera enhances optical networking capabilities


Infinera has announced a number of significant enhancements to the open line system (OLS) capabilities of its Groove G30 Network Disaggregation Platform.

The Groove G30 solution uses a modular sled-based architecture that allows network planners to configure optical transport functionality in a performance and cost-efficient way within a one-rack unit (1RU) platform.

A Solution to the Aluminum Air Battery Issue | Design News


Metal air batteries are among the lightest and most energy-dense electrochemical storage devices.

They use an anode made from a pure metal and a cathode that uses oxygen from the air. Metal air batteries are typically primary (non-rechargeable) single-use batteries.

Aluminum air batteries are particularly interesting for several reasons. The energy density (watt-hours per kilogram) is as much as five to ten times that of current production lithium ion cells.

Aluminum metal for the anode is extremely light and, as the cathode is air, the overall package can be much lighter than most other battery types. Aluminum is also cheap—especially when compared to the rising costs of lithium.

Where Smaller Metros Are Driving Manufacturing’s Revival

Manufacturing continues to boom within the surging U.S. economy and, over the eight years since the Great Recession ended, businesses operating in smaller metropolitan areas are driving the revival. As larger traditional hubs tend to remain stagnant, conditions in places you might not expect—including Grand Rapids, Mi.; Raleigh, N.C.; and Pittsburgh—promote manufacturing growth while offering optimism that the newfound prosperity can last.

There’s a battle for talent, and instead of manufacturers recruiting individuals to big cities—a difficulty within the current dynamics of the economy—companies are going where a growing diversity of potential employees already live.

Ecological Traps Could Effectively Control Mosquitoes


Researchers from the University of Maine have found that ecological traps could be potentially effective in controlling pest species and inhibiting the spread of infectious diseases.

In recent decades, mosquito management strategies have relied almost exclusively on insecticides in aquatic larval habitats. However, due to the evolution of insecticide resistance in mosquitoes, impacts on other species and perceived and actual risks to the environmental and public health this method has become ineffective.

Ecological traps occur when organisms show preference for low-quality habitats over other available high-quality sites. The mechanisms generating ecological traps could provide the tools needed to create traps on demand to control pest species.

The Present Phase of Stagnation in the Foundations of Physics Is Not Normal


Nothing is moving in the foundations of physics.

One experiment after the other is returning null results: No new particles, no new dimensions, no new symmetries.

Sure, there are some anomalies in the data here and there, and maybe one of them will turn out to be real news. But experimentalists are just poking in the dark. They have no clue where new physics may be to find. And their colleagues in theory development are of no help.

Some have called it a crisis.

But I don’t think “crisis” describes the current situation well: Crisis is so optimistic.

In Space, No One Can Hear You Scream | Via Satellite


Complexity is the enemy of cybersecurity. Complexity introduces risk in ways that are hard to predict. The more complex a system is, the easier it becomes for adversaries to attack, and the harder it becomes for defenders to defend.

If you are in the business, you know the complexity first hand. Satellites, planetary probes, and manned platforms all require precision engineering and embedded computer and communications systems that must function with extreme reliability. Communications to and from space objects require well engineered ground stations with specialized communications equipment and extreme security to make sure only authorized commands are processed by the space object. Depending on the mission of the space object, communications down may also need these extreme levels of security.

Adding to this complexity is the fact that no space object stays within the airspace of any particular nation. Space is a domain where no nation has ownership and all nations may operate.

Imec, CEA-Leti Form AI and Quantum Computing Hub | EE Times

Edge AI is considered now to hold the promise of solving many societal challenges — from treating diseases that cannot yet be cured today, to minimizing the environmental impact of farming. Decentralization from the cloud to the edge is a key challenge of AI technologies applied to large heterogeneous systems. This requires innovation in the components industry with powerful, energy-guzzling processors.

This is where imec and CEA-Leti hope to develop a European center of excellence.

There’s More to The RISC-V China Story | EE Times

.. as important as are these details, the gist of what I pointed out in my original blog prevails. RISC-V activities in China are complex, and they are getting fragmented.

The United States right now has one RISC-V Foundation, which seems like enough.

China has yet to explain why it needs more than one industry group to promote RISC-V. Even more mysterious is that there appears to be no direct communication or coordination between two apparently competitive industry groups.

Denso Takes Equity Stake in Infineon | EE Times

Japanese automotive components supplier Denso Corp. grabbed a stake in German chipmaker Infineon Technologies, investing an undisclosed amount described as “the mid-double-digit million-euro amount.”

Denso and Infineon aim to accelerate development of new and emerging automotive technologies — including automated driving, vehicle electrification and electro-mobility — using Infineon’s intelligent sensors, microcontrollers and power semiconductors.
