The secret to a long life? For worms, a cellular recycling protein is key

Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that worms live longer lives if they produce excess levels of a protein, p62, which recognizes toxic cell proteins that are tagged for destruction. The discovery, published in Nature Communications, could help uncover treatments for age-related conditions, such as Alzheimer’s disease, which are often caused […]

Large atmospheric waves in the jet stream present risk to global food production

In a new study published today in Nature Climate Change, scientists show how specific wave patterns in the jet stream strongly increase the chance of co-occurring heatwaves in major food producing regions of Northern America, Western Europe and Asia. Their research finds that these simultaneous heatwaves significantly reduce crop production across those regions, creating the […]

Post-menopausal killer whale grandmothers improve the chances of survival for their grand-calves

Post-menopausal killer whale grandmothers improve the chances of survival for their grand-calves, new research has found. The study found that grandmothers who were no longer able to reproduce had the biggest beneficial impact on the survival chances of their grand-offspring. This may be because grandmothers without calves of their own are free to focus time […]

Some stress in early life extends lifespan, research in roundworms shows

Some stress at a young age could actually lead to a longer life, new research shows. University of Michigan researchers have discovered that oxidative stress experienced early in life increases subsequent stress resistance later in life. Oxidative stress happens when cells produce more oxidants and free radicals than they can deal with. It’s part of […]

How does language emerge? New study provides insights into the first steps

How did the almost 6000 languages of the world come into being? Researchers from the Leipzig Research Centre for Early Childhood Development at Leipzig University and the Max Planck Institute for Evolutionary Anthropology have tried to simulate the process of developing a new communication system in an experiment — with surprising results: even preschool children […]

Global levels of biodiversity could be lower than we think, new study warns

Biodiversity across the globe could be in a worse state than previously thought as current biodiversity assessments fail to take into account the long-lasting impact of abrupt land changes, a new study has warned. The study by PhD graduate Dr Martin Jung, Senior Lecturer in Geography Dr Pedram Rowhani and Professor of Conservation Science Jörn […]

First recording of a blue whale’s heart rate

Encased in a neon orange plastic shell, a collection of electronic sensors bobbed along the surface of the Monterey Bay, waiting to be retrieved by Stanford University researchers. A lunchbox-sized speck in the vast waters, it held cargo of outsized importance: the first-ever recording of a blue whale’s heart rate. This device was fresh off […]

Using fungi to search for medical drugs

An enormous library of products derived from more than ten thousand fungi could help us find new drugs. Researchers from the group of Jeroen den Hertog at the Hubrecht Institute, in collaboration with researchers from the Westerdijk Institute and Utrecht University, have set up this library and screened it for biologically active compounds. They tested […]

What keeps cells in shape? New research points to two types of motion

The health of cells is maintained, in part, by two types of movement of their nucleoli, a team of scientists has found. This dual motion within surrounding fluid, it reports, adds to our understanding of what contributes to healthy cellular function and points to how its disruption could affect human health. “Nucleolar malfunction can lead […]

Estimating the environmental impact of Bitcoin mining

As an alternative to government-issued money, the cryptocurrency Bitcoin offers relative anonymity, no sales tax and freedom from bank and government interference. But some people argue that these benefits have an enormous environmental impact, particularly with regard to Bitcoin mining — the process used to secure the cryptocurrency. Now, researchers reporting in ACS’ Environmental Science […]
