Researchers at the Francis Crick Institute have found a vital mechanism, previously thought to have disappeared as mammals evolved, that helps protect mammalian stem cells from RNA viruses such as SARS-CoV-2 and Zika virus. The scientists suggest this could one day be exploited in the development of new antiviral treatments.

On infecting a host, a virus enters cells in order to replicate. For most cells in mammals the first line of protection are proteins, called interferons. Stem cells, however, lack the ability to trigger an interferon response and there has been uncertainty about how they protect themselves.

Changing climate patterns have left millions of people vulnerable to weather extremes. As temperature fluctuations become more commonplace around the world, conventional power-guzzling cooling and heating systems need a more innovative, energy-efficient alternative, and in turn, lessen the burden on already struggling power grids.

In a new study, researchers at Texas A&M University have created novel 3D printable phase-change material (PCM) composites that can regulate ambient temperatures inside buildings using a simpler and cost-effective manufacturing process...

Seismic activity could give scientists a read on the thickness of the ice encasing the moon and the oceans believed to lie beneath. Tidal stresses may be causing constant icequakes on Saturn’s sixth largest moon Enceladus, a world of interest in the search for life beyond Earth, according to a new study. A better understanding of seismic activity could reveal what’s under the moon’s icy crust and provide clues to the habitability of its ocean.

Scientists from Trinity College Dublin are homing in on a recipe that would enable the future production of entirely renewable, clean energy from which water would be the only waste product.

Using their expertise in chemistry, theoretical physics and AI, the team is now fine-tuning the recipe with the genuine belief that the seemingly impossible will one day be reality.

Initial work in this area, reported just under two years ago, yielded promise. That promise has now been amplified significantly in the exciting work just published in leading journal, Cell Reports Physical Science.
