Researchers found a “frozen” construction site from 79 AD in the house Domus IX 10, 1 in Pompeii, with piles of dry mixtures, tools, and walls in various phases. Analyses confirm hot mixing with quicklime, lime clasts, and reaction rims that explain the self-healing of Roman mortars.
New analysis by MIT and the PETAL consortium shows that relapse within 12 months (TTR12) in nodal mature T-cell lymphomas strongly predicts poorer five-year outcomes. The signal guides early selection of targeted therapy and enrollment in clinical trials, instead of classic second-line chemotherapy.
Thirdhand smoke consists of persistent residues of nicotine and other chemicals on surfaces and in dust that are re-released into the air. It particularly endangers infants and asthmatics. From January 1, 2026, California requires mandatory disclosure of exposure in real estate transactions, and experts recommend a total ban on smoking indoors and thorough remediation of contaminated spaces.
A new series of papers in The Lancet journal summarizes evidence on the impact of ultra-processed food on health, from obesity to diabetes, and highlights the urgency of protecting children from marketing. We analyze what UPF is according to the NOVA system, which policies the WHO and states propose, examples from Brazil and the USA, and practical steps to reduce the share of UPF in the diet.
In China, a genetically modified pig liver was successfully transplanted into a living patient for the first time. The auxiliary xenograft took over key organ functions for almost six months and opened a new possibility for treating patients with severe liver damage and a lack of human donors. This pioneering procedure is considered an important step in the development of transplant medicine.
A new theoretical model by Japanese physicists suggests that cosmic knots, formed immediately after the Big Bang, could have created the crucial matter-antimatter excess and left a recognizable signature in the background of gravitational waves, making them one of the most intriguing hypotheses about the origin of the universe as we know it.
