Zika virus uses cells' 'self-care' system to turn against host

A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the host proteins that the virus has employed to get into those cells in the first place. Read more ›

Nordic studies show the significance of old-growth forests for biodiversity

Researchers conducted a systematic review of 99 scientific publications that compared the flora or fauna of old-growth forests, managed forests and clearcut sites in boreal Europe. The reviewed studies showed large differences in the species communities inhabiting these forest types. The species richness of full-canopy forests increases as the forest gets older. Clearcut sites are also species-rich, but they are inhabited by a distinct set of species in comparison to... Read more ›

Location matters: Belly fat compared to overall body fat more strongly linked to psoriasis risk

Researchers have found that central body fat, especially around the abdomen, is more strongly linked to psoriasis risk than total body fat, particularly in women. This link between central fat and psoriasis remained consistent regardless of genetic predisposition, indicating that abdominal fat is an independent risk factor. The study provides insights that could help improve early risk prediction and guide personalized prevention strategies. Read more ›

Home water-use app improves water conservation

A new study has found that a smartphone app that tracks household water use and alerts users to leaks or excessive consumption offers a promising tool for helping California water agencies meet state-mandated conservation goals. The study found that use of the app -- called Dropcountr -- reduced average household water use by 6%, with even greater savings among the highest water users. Read more ›

Without public trust, effective climate policy is impossible

When formulating climate policy, too little attention is paid to social factors and too much to technological breakthroughs and economic reasons. Because citizens are hardly heard in this process, European governments risk losing public support at a crucial moment in the climate debate. Read more ›

'Raindrops in the Sun's corona': New adaptive optics shows stunning details of our star's atmosphere

Scientists have produced the finest images of the Sun's corona to date. To make these high-resolution images and movies, the team developed a new 'coronal adaptive optics' system that removes blur from images caused by the Earth's atmosphere. Their ground-breaking results pave the way for deeper insight into coronal heating, solar eruptions, and space weather, and open an opportunity for new discoveries in the Sun's atmosphere.

A chip with natural blood vessels

Miniature organs on a chip could allow us to do scientific studies with great precision, without having to resort to animal testing. The main problem, however, is that artificial tissue needs blood vessels, and they are very hard to create. Now, new technology has been developed to create reproducible blood vessels using high-precision laser pulses. Tissue has been created that acts like natural tissue. Read more ›
