Venus' strange rotation was likely triggered by a high-velocity, moon-sized impactor‎

Venus' bizarre and extraordinarily slow retrograde rotation on its axis has long puzzled planetary scientists. But in a new paper presented at the recent European Geosciences Union General Assembly in Vienna, the authors argue that their models indicate a high-angle, moon-sized, high-velocity impactor likely triggered Venus' strange 248-day rotation. And it probably happened within the first 50 million years of Venus' formation.

Electron beam curing could unlock tougher, faster coatings for packaging and cars‎

Coatings are everywhere. A thin protective layer, often barely visible. They keep out moisture, sunlight and rust, helping products last longer. Think of laminate on kitchen cabinets, automotive body coatings or the outer layer of a soda can or chip bag.

Traditional legal systems are ill-equipped for the fast-moving realities of climate change, study warns‎

Traditional legal systems around the world are increasingly ill-equipped to cope with the fast-moving impact of climate change on communities, new research warns. Courts and authorities that control planning and local services must follow rigid rules that are based on people's rights and environmental protection. However, changes to make laws more dynamic and responsive could help those who enforce them move beyond reacting to events and become more proactive as they manage urban spaces.

Fungal highways are vast, yet hidden underground—new study‎

Beneath our feet lie some of the largest living organisms on Earth. Fungi are mostly invisible and largely overlooked, but they help sustain the ecosystems and food systems that we depend on every day.

Children learn life lessons from movies like Moana‎

Children not only enjoy watching movies like Moana, but also learn lessons from them and apply those lessons to their own lives. That is the conclusion reached by communication scientists at Radboud University. For example, a movie can inspire children not to give up, to work together and to develop their own identity. In addition, movies can encourage children to think about social issues such as climate change and beauty standards.

Brazil catchment models reveal opposite climate impacts on Amazon and Cerrado soils‎

A comparative modeling study of two Brazilian rain catchments suggests that climate change will have contrasting effects on future soil erosion in the Amazon and Cerrado. The findings have implications for land management in both biomes in the coming decades.

How plants rush energy to injured tissues to help them heal‎

A new study finds that plants respond to injury by actively redirecting sugars to damaged tissues, helping fuel the regeneration process. Using a fluorescent sensor to track sugar movement in living plants, researchers have discovered that wounds trigger a localized shift in energy transport, concentrating glucose around the injury site. The findings published in PNAS offer new insight into how plants coordinate repair and recovery and could help scientists better understand the mechanisms that support resilience in crops facing physical damage or environmental stress.

Bacteria reveal 'glue' protein that fastens antibiotic-resistant outer membrane to cell wall‎

Researchers at the University of Notre Dame and collaborators have discovered a key process in how the outer membrane of gram-negative bacteria attaches to the cell wall, advancing the understanding of how these bacteria frequently develop resistance to antibiotics.

Climate compensation isn't always enough for landowners‎

At first glance, it looks like a simple calculation. The state offers compensation. The climate demands action. Low-lying soils must be restored as wetlands. Yet landowners hesitate. According to anthropologist and Ph.D. student Kasper Krabbe from the Department of Agroecology at Aarhus University, that is exactly where the misunderstanding begins.
