The life of a 166-million-year-old reptile has been turned upside down. While Marmoretta oxoniensis was believed to have swum in ancient lagoons, new research reveals it spent its time climbing trees instead.

Scientists at the University of California, Riverside, have discovered how adult stem cells retain their regenerative power. The researchers demonstrate in a paper published in the journal Genes & Development that these cells rely on a group of helper

Lipids in cell membranes regulate the activity of a cancer-linked protein, cell biologists at RIKEN have discovered. This finding, published in the journal eLife, could pave the way for novel approaches to treating cancer.

A new discovery could pave the way for more effective cancer treatment by helping certain drugs work better inside the body. Scientists at Duke University School of Medicine, University of Texas Health Science Center at San Antonio, and University of Arka

A study has constructed an unprecedented pangenome map of wild and cultivated rice, and decoded the genetic architecture and diversity of rice. This study, published online in Nature on April 16, provides a powerful resource for breeding and agricultural

Researchers from the Cluster of Excellence Collective Behavior at the University of Konstanz have discovered that honey bees from the same colony have different preferences in terms of defensive behavior. While some are still hesitating, others are alread

Honeybees are essential pollinators for agriculture and natural ecosystems. Stressors like climate change, habitat loss and pesticide exposure threaten their ability to forage for pollen, a critical resource for colony survival. Researchers in Environment

Giant freshwater crayfish, longer and bulkier than today's species, roamed New Zealand 20 million years ago. They would have made a perfect snack for the crocodiles and trout-sized whitebait that cruised the waters of ancient New Zealand.

In plants, the space between cells is a key battleground during infection. To avoid recognition in this space, a strain of the bacterial tomato disease Pseudomonas syringae manipulates plants by producing a substance called glycosyrin. This substance supp

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of Darwin. One focus of current debates is whether adaptive evolution relies on many mutations with small and roughly equal effects,

UC Davis Professor Hugh Safford was hiking for pleasure in California's High Sierra when he stumbled upon a new elevation record for the Jeffrey pine, which may now be the state's highest-altitude tree. His serendipitous finding is published in the jour

Researchers from the International Institute of Molecular and Cell Biology in Warsaw (IIMCB) have described a new mechanism that improves the efficiency of mRNA-based therapies. The research findings could facilitate the development of novel therapeutics
