‘Einstein’s Biggest Blunder’ May Have Finally Been Fixed

An illustration of galaxies bending the fabric of space-time (green), and the smooth effect of dark energy (purple), which dominates the effects of gravity. (Image: © NASA/JPL-Caltech) There is a fundamental problem in physics. A single number, called the cosmological constant, bridges the microscopic world of quantum mechanics and the macroscopic world of Einstein’s theory of…

A molecular ‘atlas’ of animal development

Each cell of a developing nematode worm embryo is catalogued at the molecular level in a new paper out in Science. In this visualization of the dataset, each dot represents a single cell, its color represents the age of the embryo it came from (orange=early, green=mid, blue/red=late), and the dots are arranged so that cells with similar…

Newly Discovered Japanese Duck-Billed Dinosaur Was a Cretaceous Beach Bum

The location of its fossilized remains suggests these majestic herbivores browsed ancient shorelines, expanding our knowledge of this wildly successful group of dinosaurs.New research published today in Scientific Reports describes Kamuysaurus japonicus, a…

Hawaii’s Kilauea Volcano Unexpectedly Triggered a Gigantic Phytoplankton Bloom

The clearly visible green phytoplankton bloom during the 2018 Kilauea eruption. Image: USGS CoastguardVolcanic eruptions are typically associated with death and destruction, but the recent eruptions on Hawaii’s Big Island resulted in an unexpected biological boom—a gigantic plume of algae extending for hundreds of miles into the Pacific Ocean.From May to August 2018, an ongoing…
