Eavesdroppers can hack 6G frequency with DIY metasurface

Researchers from Rice University and Brown University demonstrate a DIY method to hack 6G frequency using office paper, inkjet printer, metallic foil transfer, and laminator. The 'metasurface-in-the-middle' attack can redirect part of a high-frequency transmission between two users, threatening the security of next-gen wireless networks.

Vaccinia virus MacGyvers a makeshift tool to repair its DNA, exposing a vulnerability that could be targeted

Researchers at Medical University of South Carolina found that blocking the enzyme polymerase reduces the virus's ability to multiply. This discovery exposes an Achilles' heel that could be targeted with a therapeutic. Polymerase is a key tool for DNA replication and repair, making the virus vulnerable to disruption.

Early days of COVID-19 pandemic brought increased anxiety for some cancer survivors

A recent study found that previous therapy interventions, including ACT, did not spare cancer survivors from increased anxiety during the COVID-19 pandemic. Researchers found that anxiety symptoms worsened over time, with participants who received ACT intervention performing worse than those who received usual care.

Highway links benefit businesses – unless they are based outside cities

A new study published in China Economic Quarterly International found that the construction of China's national trunk highway system did not benefit all regions or enterprises along the route. County-level enterprises remained at the low end of the regional industrial value chain, despite improved connectivity and efficiency improvements.

Circuit model may explain how deep brain stimulation treats Parkinson’s disease symptoms

A new circuit model provides an explanation for how deep brain stimulation (DBS) relieves Parkinson's disease motor symptoms by interrupting a vicious cycle between the subthalamic nucleus and the striatum. The model suggests that DBS restores a balance with other rhythm frequencies, enabling better movement control.

Rare genetic variants not the major contributing factors to common diseases

Researchers at Uppsala University found that rare genetic variants contribute less to common diseases than previously thought. Common genetic variants with small effects play a major role in disease risk. High-throughput sequencing technologies are crucial for identifying individuals with pronounced genetic risks, suitable for precisio...

WHO Foundation should not accept donations from the alcohol industry

The WHO Foundation's Gift Acceptance Policy does not specifically preclude donations from the alcohol industry, allowing for case-by-case acceptance. However, critics argue that this lack of transparency and safeguards against corporate influence poses a risk to the agency's integrity and public health goals.

How faulty mRNA is detected and destroyed

Researchers at the University of Cologne investigated UPF3A and UPF3B proteins involved in nonsense-mediated mRNA decay (NMD), a quality control mechanism preventing defective mRNA from being processed into harmful proteins. The study shows that both proteins have partially overlapping functions, enabling fault-tolerant activation of NMD.
