A completely solid-state, single-chip, microwave-frequency surface acoustic wave phonon laser can generate coherent phonons from thermal noise or resonantly amplify injected phonons using only a direct current bias field.

AI-designed universal coronavirus vaccine passes first human trial
Because the method does not require a needle, it could offer an alternative for people who are uncomfortable with injections. Researchers also believe it may make large scale vaccination campaigns easier and faster, particularly in settings where traditional injections are more difficult to administer.
Before human testing began, animal studies showed the vaccine could generate strong immune responses against multiple coronaviruses.
Inflammation-Induced Tumorigenesis and Metastasis
Inflammation, especially chronic inflammation, plays a pivotal role in tumorigenesis and metastasis through various mechanisms and is now recognized as a hallmark of cancer and an attractive therapeutic target in cancer. In this review, we discuss recent advances in molecular mechanisms of how inflammation promotes tumorigenesis and metastasis and suppresses anti-tumor immunity in various types of solid tumors, including esophageal, gastric, colorectal, liver, and pancreatic cancer as well as hematopoietic malignancies.
Chemists have demonstrated for the first time how RNA may have copied itself on early Earth — solving a bottleneck that had blocked the origin-of-life field for decades
A paper published in Nature Chemistry in May 2025 describes what its authors call the first demonstration of exponential RNA replication by a polymerase ribozyme under conditions that could plausibly have occurred on the early Earth. The work comes from Dr James Attwater and Dr Philipp Holliger at the MRC Laboratory of Molecular Biology in Cambridge, with co-authors at UCL Chemistry.
