Massive clusters of galaxies, some with more mass than a hundred Milky Way galaxies, have been detected from cosmic epochs as early as about three billion years after the big bang. Their ongoing star formation makes them bright enough to be detected at these distances. These kind … | Continue reading

Should we talk openly about the crisis and encourage children to change their daily practices? Or is there a risk that in doing … | Continue reading
Sean McWilliams, an assistant professor at West Virginia University, has developed a mathematical method for calculating black hole properties from gravitational wave data. He has written a paper describing his method and posted it on the arXiv preprint server. The paper has been … | Continue reading
EPFL researchers have discovered that cancer cells use exosomes to communicate with each other and send information through the bloodstream. This breakthrough opens up new possibilities for the use of cancer immunotherapy techniques. | Continue reading
The same technology that alerts a self-driving car that there's a pedestrian in the crosswalk could also warn a dairy farmer that a calf is getting sick—even if that calf is mingled among dozens of healthy ones. | Continue reading
Tunisian authorities said Friday they had seized 671 kilogrammes of illegally harvested red coral worth two million euros and arrested 10 people on suspicion of trafficking. | Continue reading
Majorana particles are very peculiar members of the family of elementary particles. First predicted in 1937 by the Italian physicist Ettore Majorana, these particles belong to the group of so-called fermions, a group that also includes electrons, neutrons and protons. Majorana fe … | Continue reading
Researchers are using zombie-like cells that behave normally on the outside, but are filled with magnetic particles inside, to screen potential drugs from natural products. | Continue reading
Proteins are the workhorses of the cell. Their activity is often controlled by adding or removing chemicals called phosphates, like switching an electrical current on or off. Measuring how many proteins are phosphorylated, or turned on, has been a roadblock for research. Because … | Continue reading
Buildings of the future may be lit by collections of glowing plants and designed around an infrastructure of sunlight harvesting, water transport, and soil collecting and composting systems.
