Gauging the forces between cells

Cell-cell junctions are important for communication, transport, signalling, waste evacuation and water homeostasis. An European project has investigated how biophysical forces can influence the fulfilment of this vast range ...

Making microscopic machines using metallic glass

Researchers in Ireland have developed a new technology using materials called bulk metallic glasses to produce high-precision molds for making tiny plastic components. The components, with detailed microscopically patterned ...

'Magnetic tongue' ready to help produce tastier processed foods

The "electronic nose," which detects odors, has a companion among emerging futuristic "e-sensing" devices intended to replace abilities that once were strictly human-and-animal-only. It is a "magnetic tongue" -- a method ...

Authenticating ancient artifacts

Resolving water's electrical properties

An old confusion about the electrical properties of water's surface has ended, thanks to scientists at Pacific Northwest and Lawrence Livermore National Laboratories. The conflict arose because two types of measurements gave ...

New 'nano-drug' hits brain-tumor target found in 2001

Nine years ago, scientists at Cedars-Sinai's Maxine Dunitz Neurosurgical Institute detected a subtle shift occurring in the molecular makeup of the most aggressive type of brain tumors, glioblastoma multiforme. With further ...

Hormonal birth control alters scent communication in primates

Hormonal contraceptives change the ways captive ring-tailed lemurs relate to one another both socially and sexually, according to a Duke University study that combined analyses of hormones, genes, scent chemicals and behavior.
