A young Picasso or Beethoven could be the next Edison

Good news for parents: Those piano lessons or random toy parts littering your floors may one day lead to the next scientific breakthrough.

That’s according to new Michigan State University research linking childhood participation in arts and crafts activities to patents generated and businesses launched as adults. (more…)

Secrets to Winterizing Your Boat

When fall comes around, it’s a sign that it’s time to start thinking about winterizing your boat.  You might get to use it for another month or so, depending on where you live, but those in colder climates should winterize their boat sooner rather than later.  Winterizing it will keep your boat protected from the ice and snow until next spring.  You don’t want to have to look for a new boat for sale because yours has been damaged, so be sure to prepare it for the cold.  Here are some of the basic steps to take to keep your boat safe.

Bald laufen wir mit «Google-Brillen» herum

Parallel zur staatlichen breitet sich eine private Überwachung grossen Stils aus. Widerstand scheint aussichtslos. (Teil 2)

Red. In einem ersten Teil befasste sich der Autor mit staatlichen Überwachungsdiensten und den möglichen Folgen für demokratische Gesellschaften. Der zweite Teil zeigt auf, welche Rolle dabei die digitale Technologie und das Internet spielen.

Zur neuen Entwicklung gehört, dass es neben der staatlichen Tätigkeit immer mehr auch Private sind (Einzelpersonen, Agenturen, Detektivbüros, Sicherheitsfirmen, privatwirtschaftlichen Unternehmen), die andere überwachen oder überwachen lassen, so dass man sagen kann, dass nach dem englischen Staatstheoretiker Thomas Hobbes (1588-1679) der Mensch nicht nur des Menschen Wolf, sondern auch dessen Grosser Bruder und Datenspeicher ist.

Stretchable energy sources

UD researchers develop stretchable wire-shaped supercapacitor

Advances in flexible and stretchable electronics have prompted researchers to explore ways to create stretchable supercapacitors — robust energy storage devices — to power these and other devices. 

Supercapacitors offer significant advantages over common batteries, including the ability to recharge in seconds, exceptionally long life span and high reliability, leading to their incorporation in portable consumer electronics, memory backup devices, hybrid vehicles and even large industrial scale power and energy management systems.

Crashing rockets could lead to novel sample-return technology

During spring break the last five years, a University of Washington class has headed to the Nevada desert to launch rockets and learn more about the science and engineering involved. Sometimes, the launch would fail and a rocket smacked hard into the ground.

This year, the session included launches from a balloon that were deliberately directed into a dry lakebed. Far from being failures, these were early tests of a concept that in the future could be used to collect and return samples from forbidding environments – an erupting volcano, a melting nuclear reactor or even an asteroid in space.

Global warming led to dwarfism in mammals — twice

ANN ARBOR — Mammal body size decreased significantly during at least two ancient global warming events. A new finding that suggests a similar outcome is possible in response to human-caused climate change, according to a University of Michigan paleontologist and his colleagues.

Researchers have known for years that mammals such as primates and the groups that include horses and deer became much smaller during a period of warming, called the Paleocene-Eocene Thermal Maximum (PETM), about 55 million years ago. (more…)

Überwachung kann Richtung Totalitarismus abgleiten

(Teil 1) Um Terroranschläge zu verhindern, kommen Instrumente zur Anwendung, die jederzeit den Wandel zu einem Polizeistaat erlauben. (1)

Das Monitoring der Menschen, ob privat oder staatlich, folgt einer eigenen Logik. Wo ausgespäht und ausgehorcht wird, sind alle verdächtig. Niemand ist ausgenommen und der Generalverdacht zur Norm geworden, wie die neueste Episode in der Geschichte der amerikanischen National Security Agency (NSA) zeigt: Sogar das Handy der deutschen Bundeskanzlerin Angela Merkel wurde von den US-Staatsschützern «abgegriffen», wie der Ausdruck lautet.
