Everyday chemicals are quietly damaging beneficial gut bacteria

Scientists have completed a large laboratory analysis of widely used human-made chemicals and found that 168 of them are harmful to bacteria that normally live in a healthy human gut. These substances slow or stop the growth of microbes that play an important role in supporting overall health. Many of…

Crolla un pino di 20 metri ai Fori Imperiali a Roma – Notizie – Ansa.it

Dopo l’ondata di maltempo che ha colpito Roma nelle ultime ore, un pino di oltre 20 metri è crollato nella serata di oggi a via dei Fori Imperiali, nella zona del Colosseo. L’albero è caduto all’altezza del punto informativo turistico, vicino agli ingressi della stazione della metro C, a un…

This CRISPR breakthrough turns genes on without cutting DNA

Scientists at UNSW Sydney have developed a new form of CRISPR technology that could make gene therapy safer while also resolving a decades-long debate about how genes are switched off. The research shows that small chemical markers attached to DNA actively silence genes, rather than simply appearing as harmless byproducts…

Plants can’t absorb as much CO2 as climate models predicted

High levels of carbon dioxide in the atmosphere are a major driver of climate change. At the same time, increased CO2 can encourage plants to grow faster, allowing them to absorb more carbon and potentially slow warming. That benefit, however, depends on whether plants have access to enough nitrogen, a…

Scientists find a safer way to make cells burn more calories

Scientists have developed experimental compounds that prompt the mitochondria inside cells to use more energy and burn additional calories. This early research suggests a possible new path toward treating obesity while also supporting better metabolic health. Obesity affects people worldwide and raises the risk of serious conditions such as diabetes…

A legendary fossil is forcing scientists to rethink human origins

An international research team led by scientists from La Trobe University in Australia and the University of Cambridge is questioning how one of the most complete early human fossils has been classified. Their findings suggest the specimen may not belong to any known human ancestor species and could represent an…

Assalto a portavalori lungo la A14 con chiodi e fumogeni – Notizie – Ansa.it

Un portavalori è stato assaltato questa mattina intorno alle 6.30 lungo l’autostrada A14, in direzione nord, all’altezza di Ortona, nel Chietino. Sul posto sono intervenute pattuglie del Coa della Polizia di Pescara, vigili del fuoco e 118. Al momento non si conosce l’entità del bottino. Sulla sede stradale i malviventi…

A missing flash of light revealed a molecular secret

Liquids and solutions may seem simple, but at the molecular level they are constantly in motion. When sugar dissolves in water, for example, each sugar molecule is quickly surrounded by shifting clusters of water molecules. Inside living cells, the situation becomes even more intricate. Tiny liquid droplets ferry proteins or…
