Manmade noise a 'major global pollutant': study

It is well known that human hubbub can have a negative impact on some animals, but a new study Wednesday says the noise we make should be treated as a "major global pollutant".

How gene expression noise shapes cell fate

Essential genes are often expressed with high variability during the development of cells. Scientists call this phenomenon "biological noise" and suspect that it is also decisive for the fate of cells, i.e. the developmental ...

Frogs' mating calls also attract predators

Frogs have been struggling a bit in recent years. Their populations around the world have been declining for decades, and the reasons for their loss come from many fronts. Like many other animals, frogs are losing their homes ...

Are humans preventing flies from eavesdropping?

Today's world is filled with background noise, whether it be from a roaring river or a well-trafficked highway. Elevated noise levels from both human-made and natural sources may interfere with animals' listening ability ...

Using correlated photons to enhance x-ray imaging

A team of researchers at Bar-Ilan University has found a way to use correlated photons to make sharper X-ray images. In their paper published in the journal Physical Review Letters, the group describes their process and suggest ...
