Nonreciprocal interactions go nonlinear

A University of Vienna team observed nonlinear and Non-Hermitian dynamics in a tabletop experiment using two glass nanoparticles. The researchers created a positive feedback loop resembling a chase-runaway dynamic, where one particle forces the other into motion, resulting in amplified amplitude and nonlinear dynamics.

Little trust in Dr. ChatGPT

A new study published in Nature Medicine found that people rate medical advice as less reliable and empathetic when an AI is believed to be involved. Despite this, respondents were still less willing to follow AI-supported recommendations compared to advice from human doctors.

65 million Americans now own firearms for protection, suggests survey

The study found that 79% of gun owners cited protection as the primary reason for owning a firearm, with increasing numbers of women and minority ethnic backgrounds citing this reason. Gun ownership has become predominantly motivated by protection, appealing to demographics beyond traditional firearm owners.

Artificial blood vessels could improve heart bypass outcomes

Researchers at the University of Edinburgh have developed strong, flexible gel-like tubes that mimic the properties of human veins. These artificial blood vessels could transform the treatment of cardiovascular diseases by replacing the current human and synthetic veins used in heart bypass surgeries.

Bilateral mastectomy and breast cancer mortality

Women with bilateral mastectomy have a greatly diminished risk of contralateral breast cancer, yet experience similar mortality rates as patients treated with lumpectomy or unilateral mastectomy. The study highlights the importance of considering long-term risks and benefits in breast cancer treatment decisions.

Fresh light on the path to net zero

Researchers from UNSW used magnetic fields to study singlet fission, a process that breaks light particles into smaller chunks, increasing efficiency. The study could lead to improved silicon solar cell technologies, potentially achieving over 30% efficiency and reducing energy costs.
