New research using fossils of whale ancestors reveals their path to becoming Earth's largest mammals

Modern cetaceans—whales and dolphins—have one of the largest size ranges of any living animal group, ranging from as small as 1.5 meters long to as much as 30. However, a new study reveals this diversity came much later ...

Pulsating blood vessels wash your brain while you sleep

The word "brainwashing" usually triggers negative associations. But our brain health for sure depends on it. Scientists at the University of Oslo have recently made new and important discoveries about how and why this happens ...

New circuit model offers insights into brain function

The thalamus and thalamic reticular nucleus are situated at the heart of the mammalian brain and are known to play a key role in a wide range of functions, including the transmission of sensory information to the cortex and ...

Across the divide: Manufacturing better batteries

Next generation lithium-based batteries provide a key component of the global strategy to meet decarbonization goals in transportation and beyond. We know lithium-based batteries provide high energy density. But there's an ...

Genome analysis just got personal

Life on Earth comes in a beautiful assortment of different shapes, sizes and colors, thanks to genetic mutations. Some mutations are beneficial, some are perilous, and some don't do much of anything. Every person has around ...
