JW Winco has developed a new type of indexing plunger -- GN 824 -- that can independently latch into edges and grooves. This is made possible by a chamfered plunger pin. When the chamfered pin encounters a raised latching geometry, it retracts and then springs back out again once it reaches the latching point. This new indexing plunger can be ordered with axial thread for fastening and a black plastic knob for operating the indexing plunger. In a clever design, the plunger pin can be adjusted by 360 degrees to ensure that it encounters the mating surface perpendicularly. This hardware is well suited for transport frames, mechanisms, or covers that need to be locked in place quickly and securely, especially without the need for manual intervention.

SPIROL is pleased to introduce a range of 2024 aluminum Press-In Inserts. Available in symmetrical (Series INS 50) and headed (INS 51) versions, the new aluminum Press-In Inserts line complements the existing brass line. Threaded Inserts are essential for reinforcing plastic components and provide a reusable thread within a bolted assembly. This ensures a proper seating torque and prevents the potential for plastic creep over time. These inserts are designed to be Pressed-In without heat and provide the lowest cost to install with acceptable joint performance for many applications.

Complex designs are still possible when grinding and polishing Fused Silica or Sapphire. Ceramic properties such as wear, abrasion resistance, and strength of these optical materials can be a designer's dream solution when high temperatures or severe environments rule out standard optical glass or plastic. INSACO is a machine shop specializing in ultra-hard and extreme materials.

Miki Pulley Magnetic Couplings are shaft couplings that transmit torque from one shaft to another using a magnetic field instead of a physical or mechanical connection. These Magnetic Couplings are non-contact and rely on the attraction and repulsion of magnetic poles to generate rotational power. The full product range can withstand significant misalignments and are silent, vibration-free, and do not generate thermal conduction. Design advantages include configurations that are versatile for use in various engagement angles and installations. Max transmittable torque is adjustable.

Parts that are light and strong are crucial to nearly every industry. To achieve better performance without risking part failure, parts must maintain a specific wall-height-to-thickness ratio and wall-height-to-length ratio. Additionally, some geometries and supports can support thin walls to achieve a lighter component weight. Dive deeper into the cost drivers behind CNC-machined thin walls in this Xometry design-for-manufacturing article.

Researchers have developed a new therapy that can be injected intravenously right after a heart attack to promote healing and prevent heart failure.
The therapy both prompts the immune system to encourage tissue repair and promotes survival of heart muscle cells after a heart attack. Researchers tested the therapy in rats and showed that it is effective up to five weeks after injection.
The research team, led by bioengineers at the University of California - San Diego and chemists at Northwestern University, published their findings in the April 25 issue of the journal Advanced Materials.
"Preventing heart failure after a heart attack is still a major unmet clinical need," said Karen Christman, one of the study's corresponding authors and a professor in the Shu Chien-Gene Lay Department of Bioengineering at the UC San Diego Jacobs School of Engineering. "The goal of this therapy is to intervene very soon after someone suffers a heart attack to keep them from ultimately going into heart failure."

The therapy could have broader applications, said Nathan Gianneschi, the paper's other corresponding author and a professor in the Department of Chemistry at Northwestern.
"This therapeutic platform has tremendous potential for several diseases, including everything from macular degeneration to multiple sclerosis and kidney disease," Gianneschi said.
The platform aims to block the interaction of two key proteins that intervene in the body's response to stress and inflammation. When the protein Nrf2 is activated, cells resist the degradation brought on by inflammation. But KEAP1 binds with Nrf2 to degrade it in turn. After a heart attack, this process of degradation has to be stopped so that tissues can heal better.
The protein-like polymer, or PLP, platform is made from a polymer that mimics Nrf2. Once injected intravenously, it finds KEAP1 and binds to it, preventing it from binding to the actual Nrf2 protein and degrading it.
Researchers injected rat models after a heart attack with either the PLP platform or a saline solution. The team was blinded to which animals received the polymer or saline. After five weeks, the rodents underwent MRIs while sedated. The animals injected with the polymer showed better cardiac function and significantly more healing in their heart muscle tissue. Other tests also showed that genes that promote healing of tissues were expressed more.
Researchers describe the study as a proof of concept. Before moving on to tests in larger mammals, they want to optimize the design and dosage, and conduct further analysis.
"Proteins are the molecular machines that drive all essential cellular function, and dysregulated intracellular protein-protein interactions are the cause of many human diseases," Gianneschi said. "Existing drug modalities are either unable to penetrate cells or cannot effectively engage these large disease target domains. We are looking at these challenges through a new lens."
The therapy method was developed by Gianneschi while he was a faculty member at UC San Diego, where he is now an adjunct faculty. He continued working on the technology at Northwestern.
This work was made possible by research grants from the National Institutes of Health National Heart, Lung, and Blood Institute.
