Bacterial adhesive is 2-3 times stronger than common commercial glues
The glue one species of water-loving bacteria uses to grip its surroundings may be the strongest natural adhesive known to science. If engineers can find a way to mass-produce the material, it could have uses in medicine, marine technology and a range of other applications.
Researchers at Indiana University in Bloomington and Brown University in Providence, R.I., studied how much force they needed to tug the tiny, stalked Caulobacter crescentus off a glass plate. As the researchers reported in the Apr. 11, 2006, Proceedings of the National Academy of Sciences, the bacteria grip with a force of 70 newtons per square millimeter--roughly 5 tons per square inch--or equivalent to the downward force exerted by three cars balancing on a spot the size of a quarter. While the researchers do not yet know if the substance is the strongest glue on Earth, it is stronger than cyanoacrylate superglues found on store shelves and may be rivaled only by a few synthetics.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
