Claw-like nanowires filter bacteria from blood

A team of researchers from institutions across China has developed a new type of dialyser —one capable of capturing up to 97 percent of bacteria present in a blood sample. In their paper published in the journal Nature ...

Hairy tongues help bats drink up

Animals have evolved all manner of adaptations to get the nutrients they need. For nectar-feeding bats, long snouts and tongues let them dip in and out of flowers while hovering in mid-air. To help the cause, their tongues ...

Nobel: Big hopes rest on tiny machines

Molecular machines, which earned their inventors the Nobel Chemistry Prize on Wednesday, are a fraction of the width of a human hair but strong enough to move things 10,000 times their size.

Dancing hairs alert bees to floral electric fields

Tiny, vibrating hairs may explain how bumblebees sense and interpret the signals transmitted by flowers, according to a study by researchers at the University of Bristol.

Gecko grippers moving on up

A piece of tape can only be used a few times before the adhesion wears off and it can no longer hold two surfaces together. But researchers at NASA's Jet Propulsion Laboratory in Pasadena, California, are working on the ultimate ...

How can we find tiny particles in exoplanet atmospheres?

It may seem like magic, but astronomers have worked out a scheme that will allow them to detect and measure particles ten times smaller than the width of a human hair, even at many light-years distance.  They can do this ...
