Though we barely notice it most of the time, the steady beating of a human heart is an amazingly complex performance. Like an orchestra, thousands of cells have to master their individual performances as well as work together. Now a team of scientists has created the first atlas of humanRead More →
UCLA biologists reveal interplay between estrogen and key gene Can women in menopause get the benefits of hormone replacement therapy without the risks? A new UCLA study conducted with mice points in that direction, but additional research is necessary. Women commonly experience hot flashes and weight gain, among other changes,Read More →
The radioactive legacy of the arms race solves a mystery about the world’s largest fish Atomic bomb tests conducted during the Cold War have helped scientists for the first time correctly determine the age of whale sharks. The discovery, published in the journal Frontiers in Marine Science, will help ensure theRead More →
Cells have a big decision: Should they replicate or sleep? Healthy cells can go either way. Cancer cells’ replication switches are stuck in the ‘on’ position. Now a study by University of Colorado Cancer Center researchers working at CU Boulder’s BioFrontiers Institute and published today in the journal Science overturns the conventionalRead More →
Researchers have found unexpected fossil traces of a temperate rainforest near the South Pole 90 million years ago, suggesting the continent had an exceptionally warm climate in prehistoric times Researchers have found unexpected fossil traces of a temperate rainforest near the South Pole 90 million years ago, suggesting the continentRead More →
UC San Diego researchers discover the enzyme SPRK1’s role in reorganizing the paternal genome during the first moments of fertilization — a finding that might help explain infertility cases of unknown cause A sperm enters an egg, an embryo develops and eventually a baby is born. But back up aRead More →
Environmental light shown to affect retention of traumatic long-term memory in flies Tokyo, Japan – Scientists from Tokyo Metropolitan University have discovered that Drosophila flies lose long-term memory (LTM) of a traumatic event when kept in the dark, the first confirmation of environmental light playing a role in LTM maintenance. The teamRead More →
A study published in the prestigious journal Nature Ecology and Evolution and led by researchers from the Laboratory of Biodiversity and Ecosystem Functioning at Universidad Pablo de Olavide (UPO) provides novel evidence that multiple elements of soil biodiversity are fundamental for maintaining the functioning of terrestrial ecosystems across global biomes A gramRead More →
What can be reused and what can be disposed of? Cells also face this tricky task. Researchers from the Biozentrum of the University of Basel have now discovered a cellular machine, called FERARI, that sorts out usable proteins for recycling. In Nature Cell Biology, they explain how FERARI works andRead More →
JGI-led team significantly expands the global diversity of large and giant viruses While the microbes in a single drop of water could outnumber a small city’s population, the number of viruses in the same drop–the vast majority not harmful to humans–could be even larger. Viruses infect bacteria, archaea and eukaryotes,Read More →
