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 ...

How stick insects honed friction to grip without sticking

When they're not hanging upside down, stick insects don't need to stick. In fact, when moving upright, sticking would be a hindrance: so much extra effort required to 'unstick' again with every step.

Nanosuits help small creatures survive a vacuum

(Phys.org) —Scientists use scanning electron microscopes (SEMs) to study tiny structures in small organisms. SEMs can only work in a high vacuum, and exposure to such a vacuum normally causes living things to die very ...

Engineers create ultra-sensitive artificial skin

(Phys.org) -- Engineers from South Korea and the United States working together have developed a new type of artificial skin that is less complex, cheaper to make and more sensitive than other electronic sensors designed ...

How mouse embryos determine left from right

RIKEN biologists have discovered how tiny hairs in embryos detect flowing fluid, which ultimately leads to the left and right sides of the embryo developing differences. As well as resolving a long-standing debate, this finding ...

Self-assembling molecules could help in cancer therapy

Treatment of cancer is a long-term process because remnants of living cancer cells often evolve into aggressive forms and become untreatable. Hence, treatment plans often involve multiple drug combinations and/or radiation ...

New method simultaneously measures flow and oxygen

An international research team headed by the Max Planck Institute for Marine Microbiology in Bremen, Aarhus University and the Science for Life Lab in Uppsala has developed tiny particles that measure the oxygen concentration ...

Flexible device could treat hearing loss without batteries

Some people are born with hearing loss, while others acquire it with age, infections or long-term noise exposures. In many instances, the tiny hairs in the inner ear's cochlea that allow the brain to recognize electrical ...
