Shark's sixth sense aid attacks from below

Wobbegong (Orectolobus maculatus) and angel sharks (Squatina australis) have evolved unique electrosensory pores that aid attacks on unsuspecting prey from beneath, according to a recent study.

The aesthetic appearance of concrete is controversial

Is a perfect concrete wall concrete without big pores? The aesthetic appearance of concrete is a controversial subject among developers, architects and building contractors. What does look like anyway? What is it that makes ...

Biochemist sheds light on structure of key cellular 'gatekeeper'

Facing a challenge akin to solving a 1,000-piece jigsaw puzzle while blindfolded—and without touching the pieces—many structural biochemists thought it would be impossible to determine the atomic structure of a massive ...

Hierarchically porous polymers with fast absorption

A research team at KAIST has developed a method to form micropores of less than 2 nanometers within porous polymers where 10 nanometers long mesopores connect like a net. The advantage of the porous polymers is fast absorption ...

'Swiss cheese' membrane with adjustable holes

A new membrane, developed by University of Twente scientists, can be made more or less porous 'on demand'. In this way, smart switching between 'open' and 'closed' is possible, which opens the way to innovative applications ...

New technique reveals a role for histones in cell division

(Phys.org) —Proteins known as histones give structure to DNA, which coils around them like string on spools. But as is so often the case in biology, it turns out there is more to these structures than meets the eye. Scientists ...

Microtomography of multiphase flows in porous media

Multiphase flow in porous media occurs in many practical situations including carbon dioxide capture and storage, enhanced oil recovery, remediation of polluted ground, and soil science.

Research hones pore-scale models

The physical and chemical processes that occur at the scale of individual soil particles dictate the way fluids flow underground over much larger scales. To more accurately predict how plumes of subsurface fluids, such as ...
