Imagine a smoke detector that, instead of warning residents of smoke before a fire engulfs their home, is placed in mass-transit locations to alert travelers and first responders to hazardous chemicals in the air.

The Interplay between KSHV Infection and DNA-Sensing Pathways
During viral infection, the innate immune system utilizes a variety of specific intracellular sensors to detect virus-derived nucleic acids and activate a series of cellular signaling cascades that produce type I IFNs and proinflammatory cytokines and chemokines. Kaposi’s sarcoma-associated herpesvirus (KSHV) is an oncogenic double-stranded DNA virus that has been associated with a variety of human malignancies, including Kaposi’s sarcoma, primary effusion lymphoma, and multicentric Castleman disease. Infection with KSHV activates various DNA sensors, including cGAS, STING, IFI16, and DExD/H-box helicases. Activation of these DNA sensors induces the innate immune response to antagonize the virus. To counteract this, KSHV has developed countless strategies to evade or inhibit DNA sensing and facilitate its own infection. This review summarizes the major DNA-triggered sensing signaling pathways and details the current knowledge of DNA-sensing mechanisms involved in KSHV infection, as well as how KSHV evades antiviral signaling pathways to successfully establish latent infection and undergo lytic reactivation.
New 3D Form of Graphene May Lead to Flexible Electronics
Graphene can support 50,000 times its own weight and can spring back into shape after being compressed by up to 80%. Graphene also has a much lower density than comparable metal-based materials. A new super-elastic, three-dimensional form of graphene can conduct electricity, and will probably pave t
Kimsuky Exploits BlueKeep RDP Vulnerability to Breach Systems in South Korea and Japan
Cybersecurity researchers have flagged a new malicious campaign related to the North Korean state-sponsored threat actor known as Kimsuky that exploits a now-patched vulnerability impacting Microsoft Remote Desktop Services to gain initial access.
The activity has been named Larva-24005 by the AhnLab Security Intelligence Center (ASEC).
“In some systems, initial access was gained through exploiting the RDP vulnerability (BlueKeep, CVE-2019–0708),” the South Korean cybersecurity company said. “While an RDP vulnerability scanner was found in the compromised system, there is no evidence of its actual use.”
Scientists Discover New “Hall Effect” That Could Revolutionize Electronics
Scientists discovered a new Hall effect driven by spin currents in noncollinear antiferromagnets, offering a path to more efficient and resilient spintronic devices.
A research team led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has identified a previously unknown type of Hall effect that could lead to more energy-efficient electronic devices.

A cool fix for hot chips: Advanced thermal management technology for electronic devices
The exponential miniaturization of electronic chips over time, described by Moore’s law, has played a key role in our digital age. However, the operating power of small electronic devices is significantly limited by the lack of advanced cooling technologies available.
Aiming to tackle this problem, a study published in Cell Reports Physical Science, led by researchers from the Institute of Industrial Science, The University of Tokyo, describes a significant increase in performance for the cooling of electronic chips.
The most promising modern methods for chip cooling involve using microchannels embedded directly into the chip itself. These channels allow water to flow through, efficiently absorbing and transferring heat away from the source.
