Birdsong and the human voice built from the same genetic blueprint

Birdsong and the human voice built from the same genetic blueprint

Recent research has revealed a common genetic link between the larynx vocal organ of mammals, reptiles and amphibians and the syrinx vocal organ of birds. This figure illustrates the evolution of the larynx and syrinx in different animal lineages. Although birds are direct descendants of dinosaurs and have a larynx and a syrinx, it is … Read more

From combustion to the wave nature of heat via the telegraphic equation

From combustion to the wave nature of heat via the telegraphic equation

The Doppler effect can be heard especially clearly when a train passes. The presence of the same effect in the generalized telegraphic equation indicates the wave nature of heat transport over small distances. Credit: IFJ PAN When a train approaches or an ambulance approaches us with its siren blaring, we hear the sound at an … Read more

Using key gene-regulated molecular pathways to increase wheat yields

Using key gene-regulated molecular pathways to increase wheat yields

A study from the University of Adelaide has revealed that the molecular pathways regulated by a gene traditionally used to control the flowering behavior of wheat can be altered to achieve greater yields. The gene is called Photoperiod-1 (PDP-1) and is regularly used by breeders to ensure that wheat crops flower and set grain earlier … Read more

New method can create water levitation at much lower temperature, has implications for cooling nuclear reactors

New method can create water levitation at much lower temperature, has implications for cooling nuclear reactors

Wenge Huang inspects material samples in Jiangtao Cheng’s lab. Credit: Alex Parrish for Virginia Tech. Sprinkle a few drops of water on a hot pan and if the pan is hot enough, the water will sizzle and the water droplets will appear to swirl and float, hovering above the surface. The temperature at which this … Read more

There are wounds that still haven’t fully healed five years after the Memorial Day tornadoes

There are wounds that still haven't fully healed five years after the Memorial Day tornadoes

After the tornadoes, our neighborhood rallied with resilience I would like to focus on the good that came from this terrible event. Immediately after the storm, the whole neighborhood came together. Within days, neighborhood leaders had coordinated with city officials to orchestrate a massive trash cleanup. This brought many new partners into our network who … Read more
