NuSTAR finds clumpy doughnut around black hole

The most massive black holes in the universe are often encircled by thick doughnut-shaped disks of material. This doughnut material ultimately feeds and nourishes the growing black holes tucked inside. Until recently, some ...

Blue-green algae efficient in 'harvesting' light

Cyanobacteria, also known as blue-green algae, have an ingenious system to prepare themselves for the coming daylight when it is dark by setting up a large 'antenna'. This antenna helps them capture light energy in an efficient ...

Tracing paths through a bottleneck

Automatic tracing of filamentary structures in medical images could improve drug screening and clinical diagnosis, and might also be useful for image analysis in other fields. Software to perform this complex task has been ...

How computers help biologists crack life's secrets

Once the three-billion-letter-long human genome was sequenced, we rushed into a new "omics" era of biological research. Scientists are now racing to sequence the genomes (all the genes) or proteomes (all the proteins) of ...

Controlling the thermodynamics of light

The concept of temperature is critical in describing many physical phenomena, such as the transition from one phase of matter to another. Turn the temperature knob and interesting things can happen. But other knobs might ...
